What’s the surface area need help ASAP
Answer:
144 m^2
Step-by-step explanation:
the front side is 9 m tall and 6 m long. The formula for the surface are of triangles is W*L/2, so 9*6=54, 54/2=27. Four sides are the same, so multiply 4 to get 108m. the the faced down part is 6m by 6m, so multiply 6*6 is 36, then add up 36 + 108 = 144m.

Simplify x^1/3(x^1/2+2x^2)
Answer:
The first choice: x^5/6 + 2x^7/3
Step-by-step explanation:
= x^1/3 * x^1/2 + x^1/3 * 2x^2
= x^(1/2+1/3) + 2x(1/3 + 2)
= x^5/6 + 2x^7/3
Answer:
x^5/6 + 2x^7/3

Chris wants to ride on the Colossal Coaster at the amusement park. Admission to the park
costs $6 and each ride on the roller coaster costs an additional $0.50. Chris wants to spend less
than $12.50 in all. Find the number of times that Chris can ride on the roller coaster.
Solve using inequalities
Answer:
He can ride it 4 times
Step-by-step explanation:
Answer:
12 times
Step-by-step explanation:
$6 + $0.50 (x) < $12.50
x is the amount of times he can ride. Since he wants to spend less then 12.50 then he can't go more then 13 times but 13 is spending all his money so 12 times is $0.50 less then his specified amount he wants to spend.

i need your help please !!!
Answer:
exponent
Step-by-step explanation:
How do you show your work on this question -x/3+2=-5
Hello!
[tex]\large\boxed{x = 21}[/tex]
[tex]\frac{-x}{3} + 2 = -5[/tex]
Begin isolating for x by subtracting 2 from both sides:
[tex]\frac{-x}{3} + 2 - 2 = -5 - 2\\\\\frac{-x}{3} = -7[/tex]
Further simplify by multiplying both sides by 3:
[tex]\frac{-x}{3} * 3= -7 * 3\\\\-x= -21[/tex]
Multiply both sides by -1 to cancel out the -x:
[tex]-x(-1) = -21(-1)\\\\x = 21[/tex]
1. John’s age is three times that of his sister. When you add John’s age to his sister's age, you get 36. How old are John and his sister?
(a) Write an equation that represents the situation. (1 point)
(b) Solve the equation from Part (a). Show your work. (3 points)
Answer:
Part A: Write an equation.
If the present age is y, then n times the present age = ny.
If the present age is x, then age n years later/hence = x + n.
If the present age is x, then age n years ago = x – n.
The ages in a ratio a: b will be ax and bx.
Part B: Solve the equation.
John’s age =
John’s sister’s age =
Answer:
sister = 6 years
John=18 years
Step-by-step explanation:
A(S) + 12 = 3 * A(S), subtracting A(S) from both sides one gets 12 = 2 * A(S). Now dividing both sides by 2 we get A(S) = 12/2 = 6 . Therefore, the age of the sister is 6 years when her brother John is three times as old, that is 18 years.
Answer:
36-x=y
y*3=x
x+y=36
Step-by-step explanation:
I wasnt really sure how to write the equation the way you're supposesd to?
John is 27 and his sister is 9. 9*3=27

Step-by-step explanation:
| - 4 | < | -6 | true or false
| - 1 | > | 7 | true or false
| -8 | < - 2 true or false
Answer:
false
false
true
Step-by-step explanation:
if it has brackets just take them away and the negative symbol
Answer:
1) | - 4 | < | -6 | is true
2) | - 1 | > | 7 | is false
3) | -8 | < - 2 is false
Step-by-step explanation:
We need to find if the statements are true or false.
1) | - 4 | < | -6 | true or false
We know that:
|-4| = 4
|-6| = 6
Now, 4 < 6 is true
So, | - 4 | < | -6 | is True
2) | - 1 | > | 7 | true or false
We know that:
|-1| = 1
Now, 1 > 7 is false, because 1 is less than 7 and not gr eater than 7.
So, | - 1 | > | 7 | is false
3) | -8 | < - 2 true or false
We know that
|-8|= 8
Now, 8 < 2 is false, because 8 is not less than 2, it is greater than 2.
So, | -8 | < - 2 is false
A greyhound dog can run with a top speed of 17.6 m/s. At this rate, how long will it take to run 100 meters?
Answer:
It will take 5.68 seconds to cover a distance of 100 meters.
Step-by-step explanation:
Given that:
A greyhound dog runs with a top speed of 17.6 m/s
Distance to cover = 100 meters
We know that:
Distance = Speed * Time
Putting the values in formula
100 = 17.6 * Time
Time = [tex]\frac{100}{17.6}[/tex]
Time = 5.68 seconds
Hence,
It will take 5.68 seconds to cover a distance of 100 meters.

Answer:
1. 0.6 and 3/5
2. 9/20
3. 44%
4. 6/8, 80%, 17/20, 0.92
5. 1/2
Step-by-step explanation:
1. 0.6 is equal to 60% because it is both 60 out of 100.
3/5 times 20 is also equal to 60 out of 100.
2. 45% as a fraction is 9/20
3. 22/50 times 2 is 44/100, which is also 44%
4. 6/8 as a percent is 75%, and then 80%, 17/20 as a percent is 85%, and 0.92 as a percent is 92%.
5. 600 out of 1320 is roughly one half.

15% of 95? and 3 1/2% of 100?
Answer:
15% of 95-14.25
3 1/2% of 100-3.5
Step-by-step explanation:
Answer:
15% of 95= 14.25
3 1/2% of 100= 3.5
Step-by-step explanation:
3 1/2% of 100= 3.5, because 1% of 100=1
15% of 95=14.25 because 10% = 9.5 and 5% of 95=4.75
4.75+9.5= 14.25

Step-by-step explanation:
Solving
[tex]\frac{x}{-6}[/tex] ≥ 12
Multiply both sides by - 6 to clear the fraction, reversing the symbol as a result of multiplying by a negative quantity.
x ≤ - 72
Since x can equal 72 then there is a closed circle at x = - 72
Since x is less than 72 then the line points to the left.
