Answer:

bc= 6

Step-by-step explanation:

since the triangles are similar, the sides are in a ratio

xz/ac = 20/4 (5:1)

yx/ba = 15/3 (5:1)

yz/bc = 5:1 = 30/6

The answer would be ?=6 because 15/3=5 20/4=5 so 30/5=6

Hope this helps

Have a great day/night

Which of these is an example of a literal equation?

RSB [31]

ANSWER

$ax-by=k$ is an example of literal equation.

EXPLANATION

A literal equation is an equation in which letters or variables are used to represent real values.

A literal equation consists of at least two letters or variables.

The first option consists of two variables but it is not an equation. It is just an expression.

The second option is not a literal equation because it consists of only one variable. This is just a linear equation in one variable. But a literal equation should have at least two variables or letters.

As for the third option, it does not even contain a variable or letter.

What is the area of the regular hexagon ABCEF? Explain your reasoning.

Reil [10]

Answer:

1350 $\sqrt{3}$ units²

Step-by-step explanation:

The regular hexagon consists of 6 equiangular triangles

The area (A) of a equilateral triangle is calculated as

A = $\frac{s^2\sqrt{3} }{4}$ ( s is the side length )

Here s = 30 , then

A = $\frac{30^2\sqrt{3} }{4}$ = $\frac{900\sqrt{3} }{4}$ = 225 $\sqrt{3}$ units²

Thus the area of the regular hexagon is

area = 6 × 225 $\sqrt{3}$

= 1350 $\sqrt{3}$ units² ← exact value

≈ 2338.3 units² ( to 1 dec. place )

Kim and jay leave at the same time to travel 25 miles to the beach. Kim drives 9 miles in 12 minutes. Jay drives 10 miles in 15

Katen [24]

23. Kim and Jay leave at the same time to travel 25 miles going to the beach. Kim drives 9 miles in 12 minutes Jay drives 10 miles in 15 minutes. Question: who will arrive first? Unit rate of Kim => 9 miles in 12 minutes => 0.75 miles / minutes => 25 / 0.75 It will take 33.33 minutes for Kim to arrive Unit rate of Jay 10 miles in 15 minutes. => 10 miles /15 minutes => 0.67 miles /minute => 25 / 0.67 It will take Jay 37.31 minutes to arrive at the beach. SO Kim will arrive first

A baker buys 19 apples of two different varieties to make pies. The total cost of the apples is $5.10. Granny Smith apples cost

Natasha2012 [34]

The baker bought 7 gala apples, and 12 granny smiths apples

Solution:

Let "x" be the number of gala apples bought

Let "y" be the number of granny smith apples bought

Cost of 1 gala apple = $ 0.30

Cost of 1 granny smith apple = $ 0.25

A baker buys 19 apples of two different varieties to make pies

Therefore,

number of gala apples bought + number of granny smith apples bought = 19

x + y = 19 --------- eqn 1

The total cost of the apples is $5.10

Therefore, we can frame a equation as:

number of gala apples bought x Cost of 1 gala apple + number of granny smith apples bought x Cost of 1 granny smith apple = 5.10

$x \times 0.30 + y \times 0.25 = 5.10$

0.3x + 0.25y = 5.1 -------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

x = 19 - y ---------- eqn 3

Substitute eqn 3 in eqn 2

0.3(19 - y) + 0.25y = 5.1

5.7 - 0.3y + 0.25y = 5.1

5.7 - 0.05y = 5.1

0.05y = 5.7 - 5.1

0.05y = 0.6

y = 12

Substitute y = 12 in eqn 3

x = 19 - 12

x = 7

Thus the baker bought 7 gala apples, and 12 granny smiths apples
