Answer:
15 cm²
Step-by-step explanation:
To find the volume of a prism you multiply the area of the end face (pentagon in this example) by the length (9 cm). Here you would reverse that and divide the volume by the length to find the area. 135/9 is 15 so the area of the pentagon is 15 cm².
In equation form would be:
V=A×L [V=volume A=area L=length]
So if you do inverse operations you would divide the volume by the length to get the area.
V/L=A

Answer:
For a = -5 and b = -1, the expression has a value of 5
Step-by-step explanation:
You just substitue a with -5 and b with -1 in the equation:
[tex]\sqrt[ 3 ]{ \dfrac{ - { 5 }^{ 3 } }{ -1 } \phantom{\tiny{!}}}[/tex]
Calculate -5 to the power of 3 and get -125
[tex]\sqrt[ 3 ]{ \dfrac{ -125 }{ -1 } \phantom{\tiny{!}}}[/tex]
Fraction [tex]\dfrac{ -125 }{ -1 }[/tex] can be simplified to 125 by dividing -125 by -1

Blake and his brother are participating in their school’s food drive. Blake has collected 6 1/3 pounds of food and his brother has collected 5 3/4 pounds of food. Their goal is to collect 14 1/2 pounds of food by the end of the month. How many more pounds of food do they still need to collect to reach their goal? Answers shown below. (Ignore the one I chose, I randomly guessed)
Answers
They will need 2 5/12 more pounds to reach their goal.
Sum and difference of fractionsGiven the following information as shown:
Amount Blake collected = 6 1/3 poundsAmount his brother collected = 5 3/4 poundsIf their goal is to collect 14 1/2 pounds of food by the end of the month, the remaining food they need to collect will be expressed as:
y =14 1/2 - (6 1/3 + 5 3/4)
y = 14 1/2 - (19/3 + 23/4)
y = 29/2 - (76+69/12)
y = 29/2 - (145/12)
y = 174-145/12
y = 29/12
y = 2 5/12
Hence they will need 2 5/12 more pounds to reach their goal.

An item is regularly priced at $75 It is now priced at a discount of 60% off the regular price. What is the price now?
Answers
Answer:
Price is $ 30
Step-by-step explanation:
Regular price = $75
Discount = 60%
First we find the 60% of 75
( 75 × 60 ) ÷ 100 = 45
Now this answer with regular price
75 - 45 = 30
MARK BRAINLIEST IF YOU UNDERSTAND
Answer:
$ 30
Step-by-step explanation:
Regular price ⇒ $ 75
Discount ⇒ 60% off the regular price
First let us find the discount that they will give.
Let us solve now.
75 × 60% = $45
And now let us find the new price of the item.
For that you have to subtract the discount by the regular price.
New price = Regular price - Discount
= $ 75 - $ 45
= $ 30

A network administrator uses the function

How long will it take for the virus to spread to 50,000 computers ?
Answers
Functions are used to represent equations and graphs
It will take the virus 10000 hours to spread to 50000 computers
How to determine the number of hoursThe equation of the function is represented as:
f(x) = 5x
When the virus spreads to 50000 computers, the function becomes
50000 = 5x
Rewrite the function as:
5x = 50000
Divide both sides by 5
x = 10000
Hence, it will take the virus 10000 hours to spread to 50000 computers

What are similar triangles?
Similar triangles are two triangles that, while not sharing the same size, have the same proportions and angles measurements. Their corresponding angles are equal and the corresponding sides are in the same ratio.
Triangle PQR is similar to triangle STU because their angles are the same, and they share the same proportions in regards to their side lengths.
To find the unknown side of a similar triangle, set up two ratios equal to each other that represent the ratios of each triangle.
n is the hypothenuse of triangle PQR, so in your ratio, n should be in a fraction with 13, the hypothenuse length of triangle STU.
The fraction that n and 13 will be set equal to should also be the same side of the different triangle. (so either both of them are the shortest legs or both of them are the longest legs of their triangles)
Let's check each answer:
n is in the denominator and 13 is in the numerator. Great! 36 is the longest leg of triangle PQR and 12 is the longest leg in triangle STU, great! This choice is wrong, however. This is because both denominators and numerators should be set equal to their respective triangles. n is in triangle PQR, while 12 is in triangle STU, so they can not be set equal to each other.15 and 5 are both the shortest legs in their triangles, great! Unfortunately, 12 and n are both not hypothenuses, so this answer is incorrect. 15 and 5 are both the shortest legs in their respective triangles, but, again, n and 12 are not both hypothenuses.n is in the denominator and 13 is in the numerator. Great! 36 is the longest leg of triangle PQR and 12 is the longest leg in triangle STU, great! And, n is set equal to 36 (they are in the same triangle) and 13 is set equal to 12 (they are in the same triangle). This is the correct answer.*To check if your answer is correct, solve for n by cross multiplication and plug in your answer into the fraction. Both sides should simplify to the same fraction*

Answer:
X = 12 / Y = 49
Step-by-step explanation:
X = 12
This is because one of those angles is a 90 degree angle, and the other is 78; After subtracting them both from 180, you're left with 12
Y= 49
I did the same procedure as above. The two far left lines are equal, which means 41 is also an angle on the other side. 180 - 90 - 41 = 49

Answers
Interval, 1 a.m. to 12 noon has the greater rate of snowfall, in inches per hour.
What is interval?First step
1am - 12 noon will gives us 11 hours
6am - 3pm will gives us 9 hours
Second step
Inches per hour for 11 hours
=33-1/11

=2.91 inches per hour
Inches per hour for 9 hours
=36-11/9
=25/11

help me find x and y please
Answers
Answer:
Step-by-step explanation:
4 angles in a quadrilateral (sorry if i spelled that wrong) add up to 360
So we have : 11x+4 + 5y +5 +5x + 13y - 5 = 360
Then, we simplify as 16x + 4 + 18y = 360
=> 16x + 18y = 356
Divide both side by 2
8x + 9y = 178
So, x is a multiple of 8 and y is a multiple of 9
Then if we keep replacing, you will eventually come to an answer of y = 10 and x = 11
