Answer:

12 inches

Step-by-step explanation:

We are using the Pythagorean theorem

a^2 +b^2 = c^2

The diagonal is c, or the hypotenuse

16^2 + b^2 = 20^2

256 + b^2 = 400

Subtract 256 from each side

256+b^2 -256 = 400-256

b^2 =144

Take the square root of each side

sqrt(b^2) = sqrt(144)

b = 12

Answer:

Step-by-step explanation:

Let the tall of the TV = x

Phythagorean Theorem

x² + 16² = 20²

x² + 256 = 400

x² = 400-256

x² = 144

x = √144 = √12*12

x = 12 inches

What is the solution to the equation 6m = 60<br><br> A. m=10<br> B. m=50<br> C. m=66<br> D. m=360
Semmy [17]
Just simplify by isolating the variable.
To do this, you need to get rid of the coefficient.
This means dividing both sides by 6.
6m / 6 = m
60 / 6 = 10
m = 10 is the answer.

Answer:

A. The number of boxes that can be packed by Ryan and Daniel each increases over time. Daniel's function has a greater rate of

change than Ryan's function indicating that Daniel can pack more boxes per hour.

Step-by-step explanation:

Given

Ryan: 3 boxes per hour

Daniel: y = 4h

Required

True statement about their functions

First, we calculate Ryan's function.

In 1 hour, he can pack 3 boxes.

In hours, he can pack 3h boxes.

So, the equation is:

y = 3h

So, we have:

y = 3h ---- Ryan

y = 4h --- Daniel

Both functions represent direct proportional functions.

So, when h increases y also increases.

<em>However, Daniel's function has a greater rate of change because</em>y = 4h<em> implies that he can pack 4 boxes per hour while Ryan can pack 3.</em>

Make u the subject- <br> 1) a=1/u + 1/2
Vlad [161]

Answer:

u=2/2a-1

Step-by-step explanation:

a=1/u +1/2

you find the LCM first which is 2u

a=2+u/2u

cross multiply

2au=2+u

subtract u from both sides

2au-u=2

u is common to the right hand side

u(2a-1)=2

divide through by 2a-1

u=2/2a-1
