Angel decides to exceed the walking challenge goal. Describe two ways you might adjust the equation or inequality in Part A to represent Angel’s decision to exceed the goal. Give an example and explain.

Answers

Answer:

Step-by-step explanation:

The original distance that Angel wanted to walk will be represented as A

Since we don't know the additional distance Angel walked it'll be represented as B

A= the amount of distance Angel wanted to walk

B= the amount of distance Angel wanted to walk past his/her challenge goal

C= the amount of distance Angel walked originally from to past her/his challenge goal

A+B=C

Example:

I decide to work for A hours today as a challenge. Within this time I'm working I decided to extend my goal another B hours.

Answer:

2x - 10 = 10 - 3x

Simplifying

2x + -10 = 10 + -3x

Reorder the terms:

-10 + 2x = 10 + -3x

Solving

-10 + 2x = 10 + -3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3x' to each side of the equation.

-10 + 2x + 3x = 10 + -3x + 3x

Combine like terms: 2x + 3x = 5x

-10 + 5x = 10 + -3x + 3x

Combine like terms: -3x + 3x = 0

-10 + 5x = 10 + 0

-10 + 5x = 10

Add '10' to each side of the equation.

-10 + 10 + 5x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + 5x = 10 + 10

5x = 10 + 10

Combine like terms: 10 + 10 = 20

5x = 20

Divide each side by '5'.

x = 4

x = 4

Each day, a bakery makes 50 loaves of
wheat bread. If that amount is 20%
of all the bread that they bake, how
many loaves do they bake each day?

Answers

If 20% is 50 loaves, we would first write it like this: 20/100 = 50/x. We would then use the butterfly method to get 20x = 5,000. To isolate the variable, we would divide both sides by 20. This gets our answer of 250 loaves a day.
Each day, a bakery makes 50 loaves ofwheat bread. If that amount is 20%of all the bread that they bake,

The answer is 8 so its a direct proportion

I think...

The constant of Proportionality is 8.

What is constant of Proportionality?

If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.

Given:

Total Baseball Caps= 30

Total amount of Cap= $240

let the number of caps sold be c.

Then, the equation is

30 c= 240

and, c= 240/30

c= 8

Hence, the constant of Proportionality is 8.

When astronauts Neil Armstrong and Buzz Aldrin first walked on
the moon in 1969, they were able to bounce from step to step!
This is because the gravitational force of the moon is about
16.5% of that of the Earth. If you visited the moon,
weighing 100 pounds on Earth, what would your weight be?

Answers

Answer:

16.5 pounds

Step-by-step explanation:

16.5% as a decimal is 0.165

0.165 x 100 = 16.5

So in conclusion you will weigh about 16.5 pounds on the moon.

About 16 if we are counting the fact that the moons gravity is about 16.5 of the earth you will weight 16.5 pounds and will be able to float!

PLEASE HELP ME!!What is the surface area of the figure?

Answers

Answer:

  B.  24 cm²

Step-by-step explanation:

The formula for the area of a triangle is ...

  A = 1/2bh

Here, you have a base of 4 cm and a height of 3 cm, so the area is ...

  A = (1/2)(4 cm)(3 cm) = 6 cm²

__

The rectangle on the right is 3+1.5 = 4.5 cm high, and 8 -4 = 4 cm wide. Its area is ...

  A = WH

  A = (4 cm)(4.5 cm) = 18 cm²

The total area is the sum of the areas of the parts:

  total area = triangle area + rectangle area

  total area = 6 cm² + 18 cm² = 24 cm²

Find the surface area of a top open cylinder

12 in radius
2 in height

Find the surface area of a top open cylinder 12 in radius 2 in height

Answers

The surface area of the top open cylinder is 6810.149 sq.cm.

A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.

Surface area of a cylinder = Base area + Lateral area

Base area of a cylinder = 2 × π × r²

Lateral area of a cylinder = (2 × π × r) × h

Therefore, here base area of a cylinder = 2× π × 12²

                                                                  = 5837.27 sq.cm.

And, lateral area of a cylinder = (2 × π × 12) × 2

                                                  = 972.8784 sq.cm.

Therefore, total surface area of a cylinder = 5837.27 + 972.8784

                                                                      = 6810.149 sq.cm.
