Answer:
C. 17
Step-by-step explanation:
I'm assuming you need the hypotenuse so to get that you do
The square root of a^2 + b^2
a squared + b squared
So it becomes square root of 8^2 + 15^2
= square root of 64 + 225
= square root of 289
= 17

helpp whats the answer
5x=15
Answer:
[tex]\boxed{\tt x=3}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]5x=15[/tex]
and asked to solve for [tex]x[/tex]. Therefore, we must isolate the variable on one side of the equation.
[tex]x[/tex] is being multiplied by 5. The inverse of multiplication is division. Divide both sides of the equation by 5.
[tex]\frac{5x}{5}=\frac{15}{5}[/tex]
[tex]x=\frac{15}{5}[/tex]
[tex]x=3[/tex]
Let's check our solution. Plug 3 in for x and solve.
[tex]5x=15[/tex]
[tex]5(3)=15[/tex]
[tex]15=15[/tex]
This checks out, so we know our solution is correct.
The solution to 5x=15 is x=3.
QUESTION 8 A motorboat leaves a harbor and travels at an average speed of 6 mph towards a small island. Two hours later, a cabin cruiser leaves the same harbor at an average speed of 12 mph toward the same island In how many hours after the cabin cruiser leaves the harbor will it be alongside the motorboat?
Answer:
2 hours
Step-by-step explanation:
Distance = rate × time
That is,
d=rt
Let
t = time (hours) cabin cruiser traveled
t + 2 = time (hours) motorboat traveled
motorboat = 6 mph
Cabin cruiser =12 mph
Motorboat distance
d=rt
d = 6(t + 2)
Cabin cruiser distance
d=rt
d = 12(t)
Equates the two distance
6(t + 2) = 12t
Open bracket
6t + 12 = 12t
12 = 12t - 6t
12 = 6t
Divide both sides by 6
t = 12 / 6
= 2
t = 2 hours
The cabin cruiser will be alongside the motorboat in 2 hours

Faith lost 2 1/2 pounds in 10 days. If
Faith lost the same amount of pounds each
day, how much weight did Faith lose per
day?
Please help me
Answer:
1/4 pound
Step-by-step explanation:
2 1/2 divided by 10
=
1/4
or
5/2 divided by 10
=
1/4
Answer: 1/4 lbs
Step-by-step explanation:
To find weight lost each day, you have to divide total weight lost 2 1/2 lbs by total number of days 10.
(2 1/2) / 10 = 5/2 * 1/0 = 1/4 lbs lost each day

Using a portion of her savings as a down payment, Sarah bought a new car in order to commute to her new job, reducing her savings account to only $2220. From her expendible income of $2440, essential expenses (fixed) are $1010 per month, essential expenses (flexible) are $500 per month, and nonessential expenses are $430 per month. Sarah has decided to reduce her nonessential expenses for 9 months to only $230 per month, in order to build her savings back up to $5820. Then she will return her nonessential expense budget to the original $430 per month. Choose the reason or reasons why Sarah would spend less money every month temporarily in order to have this fund. I. She realizes the importance of having an emergency fund. II. She wants to build up her retirement account. III.She understands that reducing expenses can increase savings. a. I b. II and III c.

Review the following equation. Redo the work for the equation. What is the
value of x?
2(x + 1) = x - 4(x-2)
2x 2 = x-4(x-2)
2x2 = x - 4x - 8
2x - 2 =-3x - 8
-6 = -5x
-6/5 = x
What is the answer?:
x= 6/5
x= 5/7
x= 7/5
x= -3/5
Explain what mistake is made in the following false statement: 3(x+4)(x+7)=(3x+12)(3x+21)
Answer: The 3x+21
Step-by-step explanation:
3(x=4) = (3x+12) The (3x+12) is being multiplied by (x+7) and the 3 should only be distributed to (x+4) which meant the the equation when simplified should have become (3x=12)(x+7).
-(x + 4) – 3x + 8 = 4(x – 3)

Answer: x=-7
Step-by-step explanation:
1) The angles of a triangle are equal to 180
2) Add your angles together and set them equal to 180 like this:
x+59+x+51+84=180
3) Combine like terms:
2x+ 194 =180
4) Subtract 195 from both sides:
2x+ 194 =180
- 194 -194
2x = -14
5) Divide by 2 on both sides
2x= -14

Ally's hair grew from 10 10 \frac{3}{4} 4 3 inches to 13 13 \frac{1}{4} 4 1 inches over 5 months. At what rate did Ally's hair grow per month?
0.5 inches a month.
I believe you subtract 13 1/4 by 10 3/4 = 2 1/2.

С
0.585
O d
0.681
Answer: The answer is B i just did this test
Step-by-step explanation:
The only number on the list that matches the rounding requirement is 0.579. Hence, the correct option is B.
What is rounding a number to some specific place?Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.
We can consider what the offered numbers are when they are rounded to hundredths:
0.574 ⇒ 0.57
0.579 ⇒ 0.58 . . . matches the requirement
0.585 ⇒ 0.59
0.681 ⇒ 0.68
The only number on the list that matches the rounding requirement is 0.579.
Hence, the correct option is B.

can someone help me with this please
Answer:
I think the answer is E.
Step-by-step explanation:
-3 -4= -7 and that's less than nine.
if x was 3 it would be -7 + 3 = -4 which is still less than nine
if x was -11 it would be -7 -11 = -18 which is also lower than nine
if x was -3 it would be -7 -3 = -10 that's less than nine as well
Answer:
I only
Step-by-step explanation:
I) 3
9 > -3 - 4(3)
9 > -3 - 12
9 > -15
9 is great than -15 so the value of 3 works.
II). -11
9 > -3 - 4(-11)
9 > -3 +44
9 > 41
9 is actually less than 41 so the value of -11 does not work
III). -3
9 > -3 - 4(-3)
9 > -3 + 12
9 > 9
9 is equal to 9, not greater than so the value of 3 does not work
What is 180(n-2)=s when solving for N
Answer:
n = s/180 +2
Step-by-step explanation:
180(n-2)=s
Distribute
180n - 360 =s
Add 360 to each side
180n -360+360 = s+360
180n = s+360
Divide each side by 180
180n/180 = s/180 + 360/180
n = s/180 +2
