Answers

Use the pythagorean theorem: a^2 + b^2 = c^2
24^2 + 7^2 = x^2
576 + 49 = x^2
x^2 = 625
√x^2 = √625
x = 25
Your answer would be X=25

plz hury i am on a test

Answers

Answer:

72

Step-by-step explanation:

18*4

12*6

8*9

Answer: LCD = 72

Step-by-step explanation:

Rewriting input as fractions if necessary:

1/8, 1/12, 7/18

For the denominators (8, 12, 18) the least common multiple (LCM) is 72.

LCM(8, 12, 18)

Therefore, the least common denominator (LCD) is 72.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1/8 = 1/8 × 9/9 = 9/72

1/12 = 1/12 × 6/6 = 6/72

7/18 = 7/18 × 4/4 = 28/72

Please help I’m confused math is hard!

Answers

Answer:

Step-by-step explanation:

basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.

first, you need to factor out the equation.

start with the original equation.

V=4x^3+10x^2+4x

factored form:

V= 2x(2x^2+5x+2)

next, you're going to want to plug in the values.

the answer asks for x=4, but you should do both.

v=2(3)(2(3)^2+5(3)+2)

do not forget to do the exponents before!

v=6(18+15+2)

v=6(35)

v=210 ft^2

that's the answer for if x was equal to 3.

V= 2x(2x^2+5x+2)

don't forget to write the original equation first.

V=2(4)(2(4)^2+5(4)+2)

V=8(36+20+2)

V=464 ft^2  

⬆is your answer! hope this helped!!

A furniture store offers free setup and delivery services to all points within a 25-mile radius of its warehouse distribution center. If you live 20 miles east and 14 miles south of the warehouse, will you incur a delivery charge? JUSTIFY YOUR ANSWER!

I am confused. I don't know what to dooo

Answers

Answer:

No

Step-by-step explanation:

you can make a right triangle with 20 and 14. To find the hypotenuse, you add

20² + 14² = h²

400+196 = h²

596<25²

596<625

which is true.

Yes , the person will get free delivery as the person lives in the 25 mile radius.

What is a Right Angled Triangle ?

A right triangle is a triangle with one of its side as 90  degree.

It is given that the person lives 20 miles east and 14 miles south of the warehouse.

The warehouse gives free delivery for people in 25-mile radius

The distance between the warehouse and the house ≤ 25 mile

To determine the distance a right angled triangle is considered

The base is 20 and height is 14 , hypotenuse = ?

Hypotenuse ≤ 25

[tex]\rm \sqrt { 20^2 + 14^2}[/tex] ≤ 25

24.43 ≤ 25

So , Yes the person will get free delivery as the person lives in the 25 mile radius.

How much will Jason earn, if he invests $8,000 at 7.5% interest rate for 18 months? How much will be in the account at the end of the 18 months?

Answers

Answer:

$8,900

Step-by-step explanation:

You don't say anything about compounding. If this problem involves only simple interest, then the interest will be i = p*r*t and the account balance will be i + p.

Here i = $8,000*0.075*1.5 (representing 18 months)

         i + $900

At the end of 18 months there will be $8,000 + $900, or $8,900, in the account.

$8,900
