Answer 1

Answer:

27 cm squared

Step-by-step explanation:

r = half of the diameter = 8 cm

area of circle = pi(r)^2 = 3.14 x (8 cm)^2 = 200.96 cm squared

area of rectangle = 16 cm x 8 cm = 128 cm squared

area of shaded region = area of the rectangle - (half of the area of the circle)

half of the area of the circle = 100.48 cm squared

therefore, area of shaded region = 128 cm squared - 100.48 cm squared

= 27.52 cm squared

The answer is 8(2x+7y) because the common factor is 8

Answer: 8(2x+7y)

Step-by-step explanation:

Factorisation here, in equation basically means, to put it into brackets.

Step 1 :

First we have to look for if anything is common, and there is! We can do the GCF of both numbers, the answer we will get will be out of the brackets.

GCF of 16 and 56 is 8

Step 2 =

No we do this =

8 x what is 16x? 2x

8 x what is 56y? 7y

so we got this = 8( 2x+7y)

So the final answer is 8(2x+7y)

Jonathan measured 2 cups of flour into a bowl on the counter. Than he spilled part of it, now there is 3/8 left. how much did he spill?

Answers

Answer:2 cups was our starting point and we were left with 3/8 cups left after he spilled it, we are looking to find how much he spilled.

We could start by making 2 into a fraction so we could minus 3/8 easily.

2 = 16/8 (Two wholes is 16 eights.)

Now solve like a regular subtraction equation.

16/8 - 3/8 = 13/8

Our answer is 13/8 which simplified as a mixed fraction is 1 5/8

According to the information in the image, it can be inferred that the length of these would be 6, 8, 6, 8.

How to identify the length of the sides of this figure?

To identify the length of the sides of this figure we must take into account the lengths shown in the model on the left. In this case we know that this figure is 6 high, 2 long and 8 wide.

Then the lengths that have an intermediate size would be 6, the longest lengths would be 8 and the shortest would be 2. From the above we can infer that the squares on the right side of the figure would be filled as follows: up: 6, 8, 6, 8.

Identify the constant of proportionality.

Answers

Answer: 10

Step-by-step explanation:

The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. 

So,

Let's take every point of the graph, than apply the equation.

When y is 10:

k = 10/1

When y is 20:

k = 20/2

When y is 30:

k = 30/3

When y is 40:

k = 40/4

When y is 50

k= 50/5

EVERY TIME, the answer is 10, take any point when this line graph is enlarged, the point on the line, are always going to be 10.

When y is (10) , then, x is 1 (as the point is in the x axis = 1

When y is (20), then, x is 2 (as the point is in the x axis = 2

The system of linear equations −3x + 2y = −6 and y equals negative one half times x plus 4 is graphed on a coordinate plane. Approximate the solution to the system.

Answers

Answer: the solution to the system of equations is approximately (3.5, 2.25)

Step-by-step explanation:

The first equation can be rewritten in the form y = mx + b, where m is the slope and b is the y-intercept, by solving for y:

-3x + 2y = -6

2y = 3x + 6

y = (3/2)x + 3

The second equation already has the form y = mx + b:

y = -1/2 x + 4

Now that both equations are in the form y = mx + b, we can graph them on a coordinate plane and find the point at which they intersect, which is the solution to the system. The x and y coordinates of the intersection point are the values that satisfy both equations simultaneously.

The x and y values of the intersection point can be found either by solving for x and y or by using the method of substitution.

By using substitution, we can substitute the value of y from the second equation into the first equation to solve for x:

-3x + 2(-1/2 x + 4) = -6

-3x + (-x + 8) = -6

-4x + 8 = -6

-4x = -14

x = 3.5

Now that we have found x, we can substitute it into either equation to find y:

y = -1/2 x + 4

y = -1/2 * 3.5 + 4

y = 2.25

So, the solution to the system of equations is approximately (3.5, 2.25).

Determine if each equation is linear or nonlinear.

Answers

Answer: Linear, Linear, Nonlinear, Linear

Step-by-step explanation:

Any equation for y where x is lacking an exponent is a LINEAR function.

Choice 3, when distributing 4x with x, produces 4x^2.

Thus, that is the only one not linear here (it is quadratic instead)

Your teacher wants to put a wallpaper border around the classroom where the ceiling meets the walls. How many feet of border should be purchased? (reminder class size 36x 42) (*Hint: Perimeter)

Answers

Answer:

156

Step-by-step explanation:

You would want to know the perimeter of the classroom. To get the perimeter, you need to know the width and the length of the classroom. Since the classroom area is 36*42, that means all you need to do is add 36 and 42 together, then time it by 2. 36+42=78 78*2=156

156 is your answer
If your teacher wants to put a wallpaper border around the classroom where the ceiling meets the walls. And the class size is 36 x 42 it’s PERIMETER so the answer is 156
