At a carnival booth, customers had to guess how many jelly beans were in a jar. Samantha guessed there were 295 jelly beans. There were actually 250 jelly beans in the jar. What is Samantha’s percent error?

Answers

Answer 1
Samantha’s percent error was 18%
Answer 2

Samantha's percent error is 15.24%.

What is Percent Error?

The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.

Given:

Samantha guessed there were 295 jelly beans.

There were actually 250 jelly beans in the jar.

So, the percent error

= (295- 250) / 295 x 100

= 45 / 295 x 100

= 0.15254 x 100

= 15.24 %

Answer:

a) Area

b) 3,848 in. cubed

Step-by-step explanation:

Since we need to find the area of a circle, we have to insert the value of the radius (diameter ÷ 2) into the equation:

\(A = \pi r^{2}\\A = \pi (70/2)^{2} \\A = 35^{2} \pi \\A = 3,848.451\\A = 3,848\)

When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

Given:

The scale factor is 1/6.

A rectangular flag is 60 centimeters by 96 centimeters.

To find the dimension of new flag:

60 x 1/6 = 10 centimeters

96 x 1`/6 = 16 centimeters.

The dimensions of a scale drawing of the flag are 10 centimeters and 16 centimeters.

Complementary angles are two angles whose sum is 90 degrees. In this problem, we're given that the angles are 2x + 20 and 3x + 40, and we know that their sum is 90 degrees. So we can set up an equation:

2x + 20 + 3x + 40 = 90

Simplifying the left side of the equation by combining like terms, we get:

5x + 60 = 90

Subtracting 60 from both sides of the equation, we get:

5x = 30

Finally, dividing both sides of the equation by 5, we get:

x = 6

Therefore, the value of x is 6.

Answer:

Step-by-step explanation:

COMPLEMENTARY ANGLES ARE THE ANGLES THAT SUM EQUALS TO 90°.

∴ 5X+60°=90°

This figure is the pre-image of a prism that has undergone a dilation with a scale factor of 3/4.What

Answers

Answer:

194.625 m

Step-by-step explanation:

First, you would have to find the sides of the dilated prism.

12 * 3/4 = 9

13 * 3/4 = 9.75

5 * 3/4 = 3.75

11 * 3/4 = 8.25

Then, you would need to calculate to find the surface area.

2(9.75 * 8.25) = 160.875

9 * 3.75 = 33.75

Finally, add both the surface area of the rectangles are triangles together.

33.75 + 160.875 = 194.625

Because we’re given 4 Ws and told that they add to 20, we can simply divide 20 by 4 to find that each W value is equal to 5 (5+5+5+5=20).
We can then use our new found information for w+w+x+x = 24. We know that W = 5, so: 5+5+x+x = 24, and then 10+2x (because there were two Xs (if it was x+x+x, it would be 3x)) so, 10+2x=24, we can subtract 10 from both sides to get 2x by itself:
2x=24-10,
2x=14,
Then to get X by itself, we can divide by 2 on both sides:
2x/2 = 14/2
x=7
So now we know X’s value, X=7
