Answer:

Equation: y = $\frac{7}{4}$ x

21/2 cups of water

Step-by-step explanation:

Plug in 7 as y and 4 as x

7 = 4k

Find k

k = 7/4

Then plug k into th equation

y = 7/4 x

For the second part of the question:

Plug in x which is 6 into the bolded equation.

y = (7/4)(6) = 42/4 = 21/2 (simplified form)

Answer:
1. Y=7/4x
2. 21/2 cups of water

Explanation:
1. 7/4 would be put in for K as the amount of loaves of bread will x.

2. Y = (7/4) (6) = 42/4 = 21/2

Y=3x-8 using function notation

maria [59]

To write it in function notation you'll convert it into a function, substituting y by f(x):

y = 3x - 8 = f(x) = 3x - 8

Hope it helped,

Solve for k: A=5k/7y

Mashutka [201]

Answer:

7/5 * A *y =k

Step-by-step explanation:

A=5k/7y

Multiply each side by 7y

A* 7y = 5k/7y * 7y

7Ay = 5k

Divide by 5

7Ay/5 = 5k/5

7/5 * A *y =k

A six-foot-tall person is standing next to a flagpole. The person is casting a shadow 1 1/2 feet in length, while the flagpole i

Answer: 20 ft

This problem can be solved by the Thales’s theorem, which states:

Two triangles are similar when they have equal angles and proportional sides

It should be noted that to apply Thales' Theorem, it is necessary to establish the two triangles are similar, that is, that they have the corresponding angles equal or that their sides are proportional to each other.

Now, if we measure the shadow of the flagpole and the shadow of the person, at the same moment, we can use the first Thales' Theorem to calculate the height of the flagpole, knowing the height of the person.

In this case we have two similar triangles (Figure attached) where $H$ is the height of the flagpole, $h=6 ft$ is the height of the person, $A=5 ft$ is the length of the shadow of the flagpole and $a=1\frac{1}{2}=1.5 ft$ is the length of the shadow of the person.
