5. Alea is 5 times 3 less than Leo's age. Alea is 40 years old. How old is Leo
kvv77 [185]

Answer:

Leo is 11 years old

Step-by-step explanation:

* Lets explain how to solve the problem

- Alea is 5 times 3 less than leo's age

- Alea is 40 years old

- Assume that leo's age is x

* Lets change the words to equation

∵ Leo is x years old

∵ Alea is 5 times 3 less than Leo's age

- That means when we subtract 3 from Leo's age and multiply the

 difference by 5 the result is Alea's age

∴ Alea's age = 5(x - 3)

- Multiply the two terms of the bracket by 5

∴ Alea's age = 5x - 15

∵ Alea is 40 years old

- Equate the expression of Alea's age by her age

∴ 5x - 15 = 40 ⇒ the equation to find Leo's age

- Add 15 to both sides

∴ 5x = 55

- Divide both sides by 5

∴ x = 11 ⇒ the solution of the equation

∵ x represents the Leo's age

∵ x = 11

∴ Leo is 11 years old

⦁ Leo designs a stand for the new statue on display at the local library. The stand is in the shape of a right trapezoidal prism
vlabodo [156]

If the surface area of the stand to be 35 ft². The number of ropes purchase is 45.3125ft and  Percent of stand area is 83%.

<h3> Number of ropes  and Percent of stand area</h3>

Given:

Base area=3ft²

Height=3.2 feet

Surface area=35ft²

a. Number of ropes

Surface area=2×Base area×Base perimeter×Height

Base perimeter(BP):

35=2×3+BP×3.2

35=6+3.2BP

Collect like term

3.2BP=35-6

3.2BP=9

Divide both side by 3.2BP

BP=29/3.2

BP=9.0625ft

Number of ropes=5×9.0625ft

Nimber of ropes=45.3125ft

b. Percent of stand area:

Percent of stand area=(9.0625ft×3.2)÷35ft²

Percent of stand area=29ft²÷35ft²×100

Percent of stand area=82.857ft×100

Percent of stand area=83% (Approximately)

Therefore the number of ropes purchase is 45.3125ft and  Percent of stand area is 83%.

The table shows ordered pairs of the function y = 16 0. 5x. A 2-column table with 6 rows. The first column is labeled x with ent
zvonat [6]

Option 3 is the correct answer. The missing values of (x, y) is (8, 20).

<h3>How do you find out the values?</h3>

Given that the function is,

y = 16 + 0.5x

The function is a linear equation that can be solved graphically. The values of both variables x and y can be found on different points along with the straight-line graph.

Also, for every value of x, there is a corresponding value of y.

For the given options, we put the values of x to find the corresponding value of y.

For option 1, put x = 0 in the given function,

y = 16 + 0.5\times 0\\y = 16

But for x=0, y= 18, hence option 1 is not correct.

For option 2, put x = 5 in the given function,

y = 16 + 0.5\times 5\\y = 18.5

But for x=5, y= 19.5, hence option 2 is not correct.

For option 3, put x = 8 in the given function,

y = 16 + 0.5\times 8\\y = 20

But for x=8, y= 20, hence option 3 is the correct answer.

Hence we can conclude that option 3 is the correct answer. The missing values of (x, y) is (8, 20).

To know more about the function, follow the link given below.
