Yes, Briggs will have enough to complete a job requiring 1900 bricks. Since he has 1910 bricks remaining and he needs only 1900 bricks to complete the work.
Given that On the basis of past experience, a contractor expects to find 4.5% Broken Brickson every truckload.
He orders 2000.
We need to see whether Briggs will have enough to complete a job requiring 1900 bricks.
How to find a percentage of a number?Example:
- 20% of M
= 20/100 x M
= 1/5 x M
- 25% of M
= 25/100 x M
= 1/4 x M
Find 4.5% of 2000.
= 4.5% x 2000
= 4.5 / 100 x 2000
= 4.5 x 20
= 45 x 2
= 90
The remaining bricks are:
= 2000 - 90
= 1910
We see that Briggs will have enough to complete a job requiring 1900 bricks.
1910 > 1900.
Thus, Briggs will have enough to complete a job requiring 1900 bricks.
Since he has 1910 bricks remaining and he needs only 1900 bricks to complete the work.

The grid above shows the graph of the parent function

and a translated functions graph.
Write the equation for the translated graph.
Ps: please only answer if you can explain it/help me understand it.
The parent function, f(x) = |x|, and the graph of the parent and translated function, gives the equation of the translated graph as; f(x) = |x + 3|
Which equations can be used to represent the given graphs?The given parent function is; f(x) = |x|
From the parent function, we have;
When x = 0, f(0) = 0
The graph of the parent function is therefore the red graph.
The location of the vertex of the translated graph is at (x - 2, y + 1)
Given that the slope of the image of the graph of the parent function is the same as the slope of the graph of the parent function, we have;

An astronaut on the moon throws a baseball upward. The astronaut is 6 ft, 6 in. tall, and the initial velocity of the ball is 40 ft per sec. The height s of the ball in feet is given by the equation s equals negative 2.7 t squared plus 40 t plus 6.5s=−2.7t2+40t+6.5, where t is the number of seconds after the ball was thrown. Complete parts a and b. a. After how many seconds is the ball 10 ft above the moon's surface?
The ball when thrown at initial velocity of 40ft/sec is 10 ft above the moon's surface after approximately 0.09 seconds and 14.73 seconds .
When an item is moving, its velocity is the rate at which its direction is changing as seen from a certain point of view and as measured by a specific unit of time.
The given equation for the height of the ball from the surface after t seconds is given by :
s=-2.7t²+40t+6.5
The initial velocity is 40ft/second.
the height of the ball is 10 ft from the surface.
therefore: s=10
Substituting the value in the equation we get:
10=-2.7t²+40t+6.5
or, -2.7t²+40t-3.5=0
This is a quadratic equation in t . Solving by the quadratic formula we get:
We know that for a equation: ax²+bx+c=0
[tex]{\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}}[/tex]
So using the above equation we get:
[tex]{\displaystyle x={\frac {-40\pm {\sqrt {40^{2}-4(-2.7)(-3.5)}}}{2(-2.7)}}}[/tex]
either x=14.726... or x= 0.088...
Therefore x≈14.73 and x≈ 0.09
So the ball will be 10 ft above the moon's surface after approximately 0.09 seconds or 14.73 seconds .

If you could exactly afford either 2 units of x and 7 units of y, or 4 units of x and 3 units of y, then if you spent all of your income on y, how many units of y could you buy?
Answer:
11 units of y
Step-by-step explanation:
Let total income be I
We have the two equations
2x + 7y = I (1) (exactly afford 2 units of x and 7 units of y)
4x + 3y = I (2) (exactly afford 42 units of x and 3 units of y)
Multiply (1) by 2
==> 2(2x + 7y) = 2 x I
==> 4x + 14y = 2I (3)
Subtract (2) from (3)
(3) - (2)
==> 4x + 14y - (4x + 3y) = 2I - I
==> 4x + 14y - 4x - 3y = 2I
==> 14y - 3y = I (x terms cancel)
==> 11y = I
This represents an equation where if you buy 11 units of y, it will be your whole income

Type an equation for the following pattern.
Answer:
Slope(green box) = -3
Intercept(grey box) = 8
Step-by-step explanation:
To determine the best equation to represent the given pattern, we need to find two things.
First: we need to figure out the slope of the function, or in other words, how much the y value changes by each time the x value changes.
Second: we need to find the y-intercept, which is the value of y when x = 0. This value will be the constant of the function which is added to the equation each time.
To start, let's analyze the pattern to find the slope of the function...
As the x -values go up by 1 each time, the y-values are as follows:
5 --> 2 --> -1 --> -4 --> -7
It looks like the numbers decrease by 3 each time, so we can safely assume our slope is -3.
Now, let's find our intercept. We can do this by going to our lowest x value, and adding 3 (opposite direction of our slope) from its y-value to find the y-value of x = 0.
So...
When x = 1, y = 5
5 + 3 = 8
So when x = 0, y = 8, our intercept!

A) The association has a linear form.
B) The association must be positive.
C) The slope must be negative.
D) The association is weakened by outliers.
Answer:
C) The slope must be negative.
Step-by-step explanation:
Correlation coefficient between the explanatory variable x and the response variable y shows whether increases in x will result in an increase or decrease in y
Here correlation coefficient is r = -0.81
Since it is negative, that means the slope of least-squares regression line will be negative
Answer:
C. The slope must be negative.

Find the probability, correct to four decimal places, that the length of a selected Fruity
Chew is
i.
between 0.8 and 1.5 centimetres
The probability that a selected fruity chew length is between 0.8 and 1.5 cm is 0.00578.
A fruity chew's length is normally distributed with random variable X with an average width of 1.2 cm.
The standard deviation is 0.12 cm.
Therefore, mean μ = 1.2 cm and;
Standard deviation, σ = 0.12 cm
Now, the probability is given as:
z = ( x - μ ) / σ
The probability that the length of a selected fruity chew is between 0.8 and 1.5 cm.
P( 0.8 < x < 1.5 )
For, P( X > 0.8)
z = ( x - μ ) / σ
z = ( 0.8 - 1.2 ) / 0.12
z = - 0.4 / 0.12
z = - 3.33
Using the z score table,
P( X > 0.8 ) = 0.99957
For P( x < 1.5),
z = ( x - μ ) / σ
z = ( 1.5 - 1.2 ) / 0.12
z = 2.5
Using the z score table,
P( X < 1.5) = 0.99379
Therefore, the probability is between 0.8 and 1.5 cm will be:

The value of x is 7
The value of RS is 6
The value of RT is 17
Solving linear equationsFrom the question, we are to write and solve an equation for x
From the given information,
RS = 2x - 8
ST = 11
RT = x + 10
From above, we can write that
RS + ST = RT
Thus,
2x - 8 + 11 = x + 10
Solve the equation for x
2x - 8 + 11 = x + 10
2x - x = 10 - 11 + 8
x = 7
∴ The value of x is 7
Now,
For the values of RS and RT
RS = 2x - 8
∴ RS = 2(7) - 8
RS = 14 - 8
RS = 6
and
RT = x + 10
RT = 7 + 10
RT = 17

PerimeterYou will notice that the sum of vertical lengths on the right side of the figure has the same total as the vertical length on the left side:
2 + 1 + 1 = 4 . . . . units high
Likewise, the horizontal lengths at the top of the figure have the same total as the horizontal length at the bottom:
4 + 1 + 4 = 9 . . . . units wide
The perimeter is the sum of all side lengths, so is ...
P = 2(L+W) = 2(9 +4) = 26
The perimeter of the polygon is 26 units.
CompositionThe blue lines in the attachment show the area can be divided into rectangles whose area is easily computed. The top rectangle has a width of 4 units and a height of 2 units, so its area is ...
A = WH = (4)(2) = 8 . . . . square units
The middle rectangle has a width of 5 units and a height of 1 unit, so its area is ...
A = WH = (5)(1) = 5 . . . . square units
The bottom rectangle has a width of 9 units and a height of 1 unit, so its area is ...
A = WH = (9)(1) = 9 . . . . square units
AreaThe total area of the polygon is the sum of the areas of its parts:
area = top rectangle + middle rectangle + bottom rectangle
= (8 + 5 + 9) square units = 22 square units
The area of the polygon is 22 square units.
