If 1500 g can be divided evenly into batches of bread that are 70 g each, then the baker should choose the 1500 g package.

To check this, we can divide 1500 g by 70 g to see how many batches of bread can be made:

1500 g / 70 g = 21.428571428571427

Since this is a non-whole number, it means that some of the dough would be wasted if the baker chooses a package of 1500 g. The baker should choose the 1500 g package, as it can be divided evenly into batches of bread that are 70 g each.

The value of x is 4

Given that the median of the list 2x, 3x, 5x, and 8x is 12, we can arrange the list in order to find the value of x:

2x, 3x, 5x, 8x

To find the median, we need to find the middle value of the list. Since the list has an odd number of values, the median is the middle value.

2x < 3x < 5x < 8x

The median is 3x = 12, so x = 12/3 = 4

Therefore, the value of x is 4.

Negative numbers don't actually have square roots because a square can only be either positive or zero. No, we cannot find the square root of the negative value.

When two numbers of the same sign are added, the result is always positive.

Theorem: Negative Numbers' Square Roots Using the number as if it were a positive integer and adding an I in front of it as a coefficient is one way to simplify an expression that involves the square root of a negative number. Or, to put it another way, for any x, where x is a positive integer or if x is a negative number, x=ix x = I x.

The worth of root 4 is equivalent to precisely 2. In any case, the roots could be positive or negative or we can say there are dependably two roots for some random number. Subsequently, root 4 is equivalent to ±2 or +2 and - 2 (positive 2 and negative 2).

The probability that a student passed the test given that they completed the homework is 0.8 (or 80%).

To calculate this probability, we can use the formula:

P(A|B) = P(A and B) / P(B)

Where A is the event of passing the test and B is the event of completing the homework.P(A and B) is the probability that a student both passed the test and completed the homework, which is the number of students who did both divided by the total number of students in the class.

16 students passed the test and completed the homework of 28 students in total, so:

P(A and B) = 16/28 = 0.57

P(B) is the probability that a student completed the homework, which is the number of students who completed the homework divided by the total number of students in the class.

19 students completed the homework out of 28 students in total, so:

P(B) = 19/28 = 0.68

Now we can use these values to find the probability that a student passed the test given that they completed the homework:

P(A|B) = P(A and B) / P(B) = 0.57 / 0.68 = 0.8 or 80%

So, a 49-mile taxi ride would cost $19.60.

To find the cost of a 49-mile taxi ride, you first need to determine the unit price, which is the cost per mile of the taxi ride. To calculate the unit price, you can divide the total cost of the 18-mile ride by the distance traveled. In this case, the total cost of the 18-mile ride is $7.20, and the distance traveled is 18 miles.

$7.20 ÷ 18 miles = $0.40 per mile

This means that the unit price, or the cost per mile, is $0.40. To find the cost of a 49-mile taxi ride, you can then multiply the unit price by the distance of the desired ride.

$0.40 per mile x 49 miles = $19.60

Step-by-step explanation:

Go to point A and draw a line straight down, perpendicular to HT.  Let's label the point where your drawn line hits AT as B.  Now you have the line segments HB, BT.  

HB + BT = 100

Solve for the height of the triangle, BA.

BA = sin35(80) = 45.9

HB = cos35(80) = 65.5

BT = 100 - 65.5 = 34.5

Now you can solve for AT, which is the hypotenuse of ΔBAT:

(AT)² = 45.9² + 34.5² = 3295

The formula for the area of a triangle is A = 1/2 * b * h, where b is the length of the base and h is the height of the triangle. To solve for h, rearrange the formula to 2*A/bh = 2*28/10h = 5.6 yards.

Height is a measure of vertical distance, often measured from the ground up. Its most typical application is to express the size of a person, object, or other item. Height is often measured in inches, feet, and millimetres. It is also used to determine the elevation of a piece of land or a building.

To calculate the height of a triangle, use the area of a triangle formula, A = 1/2 * b * h, where b is the length of the base and h is the height of the triangle. Because we know the triangle's area is 28 square yards and its base length is 10 yards, we can rearrange the formula to find h:

h = 2*A/b

h = 2*28/10

h = 5.6 yards

As a result, the triangle's height is 5.6 yards.

Step-by-step explanation:

Divide 28 by 4,  gives you 7. So the parenthesis has to equal 7, i.e 6+1 equals 7.

The height of the cone is sin 210° × 12 cm = 10.39 cm.

Height is the measure of vertical distance, either how "tall" something or someone is, or how "high" the point is. It is typically measured in either centimeters or feet and inches, and is most commonly used to describe the stature of a person. Height is an important physical characteristic, as it affects a person's overall body proportions and can influence their physical appearance.

The curved surface area of the cone can be calculated using the formula: 2πrh. Where π is the constant pi, r is the radius of the circle, and h is the height of the cone. The height of the cone can be determined by using the trigonometric function sine, where 210° is one of the angles of the triangle. Therefore, the height of the cone is sin 210° × 12 cm = 10.39 cm.

Using the formula 2πrh, the curved surface area of the cone is 2 × π × 12 cm × 10.39 cm = 75.52 cm². As the volume of a cone is one-third the product of its curved surface area and its height, the volume of the cone is 25.17 cm³ (rounded to three significant figures).

the system of linear equations by graphing - y=-x+7,  y=x+1; values for y is (6,6).

A linear equation is an equation in which the highest power of the variable is 1. The general form of a linear equation is "ax + b = 0", where "a" and "b" are constants and "x" is the variable. For example, "2x + 3 = 0" is a linear equation. The solution to a linear equation is the value(s) of the variable that make the equation true. Linear equations can be solved using various methods such as algebraic manipulation, substitution and elimination. Linear equations can be represented graphically as a straight line, and the solution of the equation is the point where the line crosses the x-axis (or y-axis if the equation is in terms of y). Linear equations have a wide range of applications in many fields, including physics, engineering, economics, and many others.

To solve the system of linear equations by graphing, we can first graph each equation on the coordinate plane.

y = -x + 7 represents a line with a slope of -1 and y-intercept of (0,7) y = x + 1 represents a line with a slope of 1 and y-intercept of (0,1)

If we graph these two lines, we can see that they intersect at a single point, which represents the solution to the system of equations.

The x-coordinate of the point of intersection can be found by setting y equal to each other and solving for x. x = y

And the y-coordinate of the point of intersection can be found by setting x equal to each other and solving for y. y = x

Therefore the solution of the system is (x,y) = (x,x) = (6,6)

So the solution of the system is (6,6)

We can check this point by substitute x=6 and y=6 in each equation of the system and see if it makes both equations true.

y = -6 +7 = 1 y = 6 + 1 = 7

So the point (6,6) is a solution for the system of equations.

The value of x = -1 and y = 3.

To solve the system of equations using substitution, we can start by isolating one of the variables in one of the equations. For example, in the first equation, 7x - y = -10, you can add y to both sides to get y = 7x + 10.

Then we can substitute this expression for y into the second equation, 3y - x = 10, to get:

3(7x + 10) - x = 10

This simplifies to:

21x + 30 - x = 10

20x = -20

x = -1

Now we know that x = -1, we can substitute that back into the first equation or the expression we found for y to find the value of y

y = 7x + 10

y = 7(-1) + 10

y = -7 + 10
