What is the length of the hypotenuse?

erma4kov [3.2K]

Answer:

The answer is c = 17 feet

Step-by-step explanation:

The formula to find the hypotenuse is a^2 + b^2 = c^2 (a squared plus b squared equals c squared).

a = 8 feet

b = 15 feet

a^2 = 8 * 8 = 64

b^2 = 15 * 15 = 225

The next step is to add: 64 + 225 = 289

But we need to remember to square root 289 because we squared a and b.

The square root of 289 equals 17

c = 17 feet

Solve for x <img src="https://tex.z-dn.net/?f=6x%20-%202%20%3D%204x%20%2B%2013" id="TexFormula1" title="6x - 2 = 4x + 13" alt

solniwko [45]

x = $\frac{15}{2}$

subtract 4x from both sides of the equation

6x - 4x - 2 = 13

2x - 2 = 13

add 2 to both sides

2x = 13 + 2 = 15

divide both sides by 2

x = $\frac{15}{2}$

Can someone please help me with this (thank you)

pickupchik [31]

Answer:

D. ( 3.6 , 2.2)

Step-by-step explanation:

Given

x + y = 5.8....equation 1

y = 2x - 5 ......equation 2

Putting equation 2 in equation 1

x + 2x - 5 = 5.8

3x = 5.8 + 5

3x = 10.8

Therefore x = 3.6

Now

y = 2 * 3.6 - 5

= 7.2 - 5

= 2.2

Hope it will help you.

During a day a student spends 7 hours sleeping, ¹/4 of the day studying and of the time travelling. What fraction of the day is

Fiesta28 [93]

Answer:

$\dfrac{5}{24}$

Step-by-step explanation:

Time Spent Sleeping=7 hours
Time Spent Studying= $\frac{1}{4}$ of the day
Time Spent Travelling= $\frac{1}{4}$ of the day

There are 24 hours in a day, therefore:

Time Spent Studying= $\frac{1}{4}$ X 24 =6 Hours
Time Spent Travelling= $\frac{1}{4}$ X 24 =6 Hours

The total hour used for sleeping, studying and travelling=7+6+6=19 hours

Hours used for other things=24-19=5 hours

Therefore, the fraction of the day used for other things= $\dfrac{5}{24}$
