Ram and Shyam laid 80 and 170 bricks respectively.
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, Two workers laid 250 bricks. If Ram had laid twice as many as he did and Shyam had laid half as many as Ram did, there would have been 50 bricks left over.
Let each of them initially laid x and y bricks,
Therefore, establishing the equations,
x + y = 250....(i)
According to later condition,
2x + x/2 = 200
4x + x = 400
5x = 400
x = 80
Put x = 80, in equation (i)
80 + y = 250
y = 170

So, the coordinates of the images S', R', T' under the translation are (11,9), (-4,-6) and T'(h+4,k-5) respectively.
a) For the point S(7,14), we are given the translation defined by (x,y) -> (x+4, y-5). This means that for any point (x,y), we add 4 to the x-coordinate and subtract 5 from the y-coordinate to find the image of that point. Applying this transformation to the point S(7,14) gives us the image point S'(7+4, 14-5) = S'(11,9). So the coordinates of the image S' is (11,9)
b) For the point R(-8,-1), we are given the same translation defined by (x,y) -> (x+4, y-5). Applying this transformation to the point R(-8,-1) gives us the image point R'(-8+4,-1-5) = R'(-4,-6). So the coordinates of the image R' is (-4,-6)
c) For the point T(h,k), we are given the same translation defined by (x,y) -> (x+4, y-5). Applying this transformation to the point T(h,k) gives us the image point T'(h+4,k-5).
Here h and k are variables and we can't say the coordinates of image point T' without specific values of h and k. But we can say the transformation of point T as T'(h+4,k-5)
So, we have found the coordinates of the images S', R', T' under the translation defined by (x,y) -> (x+4, y-5) as (11,9), (-4,-6) and T'(h+4,k-5) respectively.

It is plausible to assume that the die is fair because there is a 3% possibility that a loaded die might randomly yield the outcomes that we saw.
The appropriate conclusion is that there is a 3% chance that a loaded die could randomly produce the results we observed. We tested this hypothesis by rolling the die 200 times and our p-value turned out to be 0.03. This means that there is only a 3% chance that the results we observed could have been produced randomly by a loaded die, so it is reasonable to conclude that the die is fair. This is because a p-value of 0.03 is considered to be statistically significant, which indicates that the results we observed are unlikely to have been due to chance. Therefore, we can conclude that the seller's claim that the die will favor the outcome 6 is likely false.

Carolyn makes and sells necklaces. The material to make each necklace costs$3. 20 Last week she made 12 necklaces and wants to make a total profit of $54Using the equation 12(X-3. 20) = 54 Carolyn determined that she will make a profit of$7. 70 on each necklace. Which error did Carolyn make?
Carolyn made an error in her calculation. She failed to take into account the cost of labor and overhead in her equation.
Her equation only accounted for the cost of materials, not the cost of labor and overhead. The equation should have been: 12(X-3.20) + Cost of Labour and Overhead = 54. This would have given her a more accurate calculation of the profit per necklace.
In addition, Carolyn did not account for other factors such as marketing, shipping, and taxes, which could also affect the total profit. If she had taken into account these other costs, she would have been able to better calculate her profit margin on each necklace. By not accounting for these costs, Carolyn could have underestimated her profit margin, leading to an inaccurate calculation.

there are 260 plants in a garden. 2/20 are flowers. how many plants are not flowers?
Answer:
To find out how many plants are not flowers, we need to subtract the number of flowers from the total number of plants.
We know that 2/20 of the plants are flowers, and we can use this information to find out how many plants are flowers. To do this, we can multiply the total number of plants (260) by the fraction of plants that are flowers (2/20).
260 x (2/20) = 260 x 0.1 = 26
So there are 26 plants that are flowers.
To find the number of plants that are not flowers, we subtract the number of flower plants from the total number of plants:
260 - 26 = 234
So there are 234 plants that are not flowers.

An astronaut on the moon throws a baseball upward. The astronaut is 6 ft, 6 in. talk and the initial velocity of the ball is 40 ft per sec. The height s of the hall in feet is given by the equation s=-2.7t^2 + 40t+6.5 , where the number of seconds after the ball was thrown. After how many seconds in the ball 22ft above the moons surface?
Answer:
Step-by-step explanation:
Using the given equation, we can solve for t when s is equal to 22.
22 = -2.7t^2 + 40t + 6.5
Subtracting 6.5 from both sides, we get:
15.5 = -2.7t^2 + 40t
Adding 2.7t^2 to both sides, we get:
18.2t^2 = 15.5 + 40t
Subtracting 40t from both sides, we get:
18.2t^2 - 40t = 15.5
Dividing both sides by 18.2, we get:
t^2 - 2.2t = 0.855
Factoring, we get:
(t - 1)(t - 0.855) = 0
Setting each factor equal to 0 and solving, we get:
t = 1 and t = 0.855
Therefore, the ball will reach a height of 22ft after 1 second and 0.855 seconds.

What are the consecutive numbers?
Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers. For example 1, 2, 3, 4, 5, 6, and so on are consecutive numbers.
consecutive numbers are defined as numbers that follow each other in the natural sequence of numbers either from largest to smallest or from smallest to largest.
Let x be the smaller odd number and y be the larger odd number. Since y is larger than x, we know that y = x + 2.
The problem states that:
2y - 2x = 21
We can substitute in the value of y:
2(x + 2) - 2x = 21
Solving for x:
2x + 4 - 2x = 21

The vertex and range of y = |x + 2| - 6 are: A. (-2, -6); -6 ≤ y < ∞.
What is an absolute value function?Generally speaking, the vertex points of an absolute value function occurs when the absolute values are equal to zeros. Therefore, we would equate the x-values of this absolute value function to zero as follows;
y = |x + 2| - 6
|x + 2| = 0
x + 2 = 0
x = -2
When x = -2, the value of y for this absolute value function is given by;
y = |x + 2| - 6
y = |-2 + 2| - 6
y = 0 - 6
y = -6
Therefore, the vertex is (-2, -6).
Since |x + 2| ≥ 0, we would add -6 to both sides of the inequality in order determine the range as follows;
|x + 2| - 6 ≥ -6

The solution is Option C.
The equation of line is given by y = -2x + 58
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 2 , 54 )
Let the second point be Q ( 5 , 48 )
The slope of the line between the points m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 54 - 48 ) / ( 2 - 5 )
On simplifying the equation , we get
Slope m = 6 / -3
Slope m = -2
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 54 = -2 ( x - 2 )
On simplifying the equation , we get
y - 54 = 2x + 4
Adding 54 on both sides of the equation , we get
y = -2x + 58
Therefore , the graph is plotted through the points ( 0 , 58 ) , ( 1 , 56 )
Hence , the equation of line is y = -2x + 58

in a jar containing dry beans, the ratio of white beans to kidney beans is 5:4. if 30 white beans were replaced with 30 kidney beans, the ratio would be 1:1. how many more white beans are there than kidney beans?
As per the unitary method, the amount of white beans are there than kidney beans are 30.
The term unitary method is known as a technique for solving a problem by first finding the value of a single unit and then finding the necessary value by multiplying the single unit value.
Here we have given that in a jar containing dry beans, the ratio of white beans to kidney beans is 5:4.
And we also know that if 30 white beans were replaced with 30 kidney beans, the ratio would be 1:1.
Here we have consider that let the number of pinto beans be x and that is the number of white beans will be x + 30
In which means the total number of beans in the jar will be written as,
=> x + x + 30 = 2x + 30
Here we know that the Total ratio is calculated as,
=> 5 + 4 = 9
In order to find the number of pinto beans then it can be calculated as,
=> ratio of pinto beans / Total ratio X Total number of beans
Which can be written as.
=> (2x + 30) = x
When we simplify this one then we get the value of x as,
=> x = 30.

The ratio of boys to girls in Ms. Cano's class is 7 to 21, there are 49 girls in the class. The total number of students in Mr. Cano's class is 196
Ratio:
In mathematics, ratios indicate the number of times one number contains another number. For example, if you have 8 oranges and 6 lemons in your fruit bowl, the ratio of oranges to lemons is 8 to 6 (that is, a ratio of 8:6, or 4:3). Similarly, the ratio of lemons to oranges is 6:8 (or 3:4) and the ratio of oranges to whole fruit is 8:14 (or 4:7). Ratios can be given by giving both constituent numbers written "a to b" or "a : b", or by giving only the value of their quotient a/b.
When comparing one data point (A) to another data point (B), the formula is A/B. That is, divide information A by information B. For example, if A is 5 and B is 10, the ratio is 5/10. Solve the equation. Divide data A by data B to get the ratio.
According to the Question:
Given:
The ratio of boys to girls is 7: 21,
and there are 49 boys,
Let number of boys be x and number of girls be y.
49/7 × 11 = 77 girls

which angles must be less than 146 degrees? please list both angles and support your answer by stating the theorem that will support your conclusion.
Any two angles whose sum is 146 degrees must both be less than 146 degrees. This can be supported by the Triangle Sum Theorem, which states that the sum of the measure of the interior angles of a triangle is 180 degrees.
The Triangle Sum TheoremThe Triangle Sum Theorem states that the sum of the measure of the interior angles of a triangle is always 180 degrees. Therefore, if two angles add up to 146 degrees, then both of those angles must be less than 146 degrees. This is because the remaining angle must make up the difference to reach the total of 180 degrees.
For example, if two angles measure 80 degrees and 66 degrees, then the third angle must measure 34 degrees in order to sum up to 180 degrees.Therefore, any two angles whose sum is 146 degrees must both be less than 146 degrees.
