No

Step-by-step explanation:

In a triangle, the sum of each 2 sides must be greater than the third side.

17 + 32 ≠ >49

17 + 32 isn't greater than 49.

I hope this helps.

Answer:

I believe the answer is the first one. definitely not the third or fourth. and it should only be exponented by t not 2t because then it'd be double what you should have.

Step-by-step explanation:

Principal=1500

Time=18months = 18×12=216

Interest=6%

now

SI=P×T×R÷100

SI=1500×216×6÷100

SI=1944000÷100

SI=19440 is the answer

Answer:

12.566

12.6 (simplified to the tenths)

12.57(simplified to the hundredths)

Step-by-step explanation:

The diameter of a circle is always double of the radius

π is always ≈ 3.14

π * 2^2 = π * 4  ≈ 12.566

Answer:

$212.50

Step-by-step explanation:

So you have to multiply 8.5 by 25 because for every hour she gets $25. And if she works for 8.5 hours then you multiply both numbers to get your answer.

Hope this helps!

Answer:

20

Step-by-step explanation:

8% × 250 =

(8 ÷ 100) × 250 =

(8 × 250) ÷ 100 =

2,000 ÷ 100 =

20;

Answer:

3.8%×250=

9.5

so the answer is 9.5

Answer:

it is the second one

Step-by-step explanation:

Answer:

A function

Step-by-step explanation:

The ONLY rule needed for a relationship to be a function is there is only ONE output for every input.

It is a function because there is only one output for every input.

Hope this helps :)

Let me know if there are any mistakes!!

Answer:

The value of 2n - 2 is 4.

Step-by-step explanation:

Given the equation

[tex]n + 7 = 10[/tex]

Subtract  7 from both sides of the equation

[tex]n+7-7=10-7[/tex]

Simplify

[tex]n=3[/tex]

Now substituting n = 3 in the equation

2n - 2 = 2(3) - 2

          = 6 - 2

          = 4

Therefore, the value of 2n - 2 is 4.

Answer:

I'm about 99.9% sure you need to know what theta is (x) so you can solve this

Step-by-step explanation:

Either that or the answer would be 0.7

Answer:

x2+5x-3x-15=x2+2x-15

Step-by-step explanation:

(x)(x)=x2,(x)(5)=5x

(-3)(x)=-3x,(-3)(5)=-15

Answer: X^2 + 8x -15

Step-by-step explanation:

Use the foil method.

First, outer, inner, last

Multiply the first numbers inside each parenthesis. X*X = x^2

Next multiply the outer number in each parenthesis. X*5 = 5x

Then multiply the inner numbers of the parenthesis. -3*x= 3x

Finally multiply the last numbers in the parenthesis. -3*5 = -15

Now add all of these together

X^2 + 5x + 3x + -15

Combine like terms

X^2 + 8x -15

X can be solved from here, however it does not seem that you are asked to solve for x

Answer:

x=0.7x+24

We move all terms to the left:

x-(0.7x+24)=0

We get rid of parentheses

x-0.7x-24=0

We add all the numbers together, and all the variables

0.3x-24=0

We move all terms containing x to the left, all other terms to the right

0.3x=24

x=24/0.3

x=80

And that's how you get 80

Step-by-step explanation:

i hope this helps.    :)

Answer: x = 80

Step-by-step explanation:

80 - 24 = 56

56 divided by 0.7 = 80

Answer:

I dont know why the answers are the same thats how i got the answer solving them

Step-by-step explanation:

answer for 9x+3y=-15  

is

x=-5/3 -y/3

y= -5 - 3x

answer for -18x-6y=30

is

x=-5/3 - y/3

y= -5-3x

Answer:

D

Step-by-step explanation:

the answer is D: Both 3 and 4

Answer:

The formula for surface area of a right triangle is A = b∙h2 where b is base and h is height.

Answer:

A = B * h2 ( [tex]A = 1/2 * base * height[/tex])

Answer:

v = 99

Step-by-step explanation:

Given v varies directly as g then the equation relating them is

v = kg ← k is the constant of variation

To find k use the condition v = 36 when g = 4 , then

36 = 4k ( divide both sides by 4 )

9 = k

v = 9g ← equation of variation

When g = 11 , then

v = 9 × 11 = 99
