The formula for surface area for a cube is 6 times the side to the power of 2
6*4^2 = 96 cm^2
What is the sum of the degrees from a diagram with 5 vertices?
Answer:
540 degrees
Step-by-step explanation:
The sum of the degrees from a diagram with 5 vertices = 540°
Hope this helps:)
Answer:
total interior degrees = 540°
Step-by-step explanation:
total interior degrees = (number of vertices x 180°) - 360°
total interior degrees = (5 x 180°) - 360° = 540°
Use elimination to solve the system of equations. Enter your answers in the boxes.
3x - 2y = 24
x + 2y = 48
X =
Hy=
v
Answer:
x = 18 , y = 15
Step-by-step explanation:
Given the 2 equations
3x - 2y = 24 → (1)
x + 2y = 48 → (2)
Adding the 2 equations term by term will eliminate the y- term
4x + 0 = 72
4x = 72 ( divide both sides by 4 )
x = 18
Substitute x = 18 into either of the 2 equations and solve for y
Substituting into (2)
18 + 2y = 48 ( subtract 18 from both sides )
2y = 30 ( divide both sides by 2 )
y = 15

Winona leaves her home at 4:15 and arrives at the theatre one fourth hour later. What time does she arrive at the theatre?
Answer:
4:30
Step-by-step explanation: if she arrives one fourth hour later its......
When Winona leaves her home at 4:15 and arrives at the theatre after one-fourth hour i.e. 15 minutes so the time when she arrived is 4:30.
Calculation of the time;Since at the time when Winona leaves her home at 4:15 and arrives at the theatre after 15 minutes
So, she arrived at the time
= 4: 15 + 15 minutes
= 4:30
Hence, When Winona leaves her home at 4:15 and arrives at the theatre after one-fourth hour i.e. 15 minutes so the time when she arrived is 4:30.

Vlad spent 20 minutes on his history homework and then completely solved x math problems that each took 2 minutes to complete. What is the equation that can be used to find the value of y, the total time that Vlad spent on his homework, and what are the constraints on the values of x and y?
y=2x+20; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20.
y=2x+20; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.
y=20x+2; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20.
y=20x +2; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.
Answer:
The answer is A. y = 2x + 20; x is any integer greater than or equal to, 0 and y is any integer greater than or equal to 20

The perimeter of a rectangular
Sheet is 120 cm. If the length is 40 cm, find its breadth.
Also find its area.
Answer:
Breadth = 20 cm
Area = 800[tex]cm^{2}[/tex]
Step-by-step explanation:
Perimeter = 120 cm
length = 40 cm
Perimeter = 2 ( L + B )
L - length B - Breadth
120 = 2 ( 40 + B )
120 = 80 + 2B
2B = 120 - 80
2B = 40
B = [tex]\frac{40}{2}[/tex] = 20 cm
Breadth = 20 cm
Area of a reactangle = Length × Breadth
= 40 × 20
= 800[tex]cm^{2}[/tex]
A sport store pays its wholesaler $40 for a baseball bat, and then sells it to a customer for $76. What is the markup rate?
Answer:
Markup 90%
Step-by-step explanation:
If $40 is 100% of the price
then
$76 is ..........x
Cross multiplication
40(x) = 76(100)
40x = 7600
Divide by 100
x = 190
190% = 100% + 90%
That means that the price is the whole price(100%) plus 90%
so the markup is 90%
ANOTHER WAY:
The difference in prices is $76-$40=$36. So, we need to find what percentage of 40 is 36.
We do this by dividing: 36/40=0.9, which is 90%. So, the markup is 90%.

paz and her scout troop makes 325 granola bars for a fundraiser. four granola bars are put in each bag. paz says that there will not be any left over. find and correct her mistake.
Answer:
Her mistake was in how many bags would be able to equally hold 4 bars.
325/4 is 81.25, which would mean there needs to be 82 bags, in which you wouldnt be able to hold 4 each equally.
A better option for Paz is to put 5 bars in each bag as 325 is an even multiple of 5. As such would result in the bag count being brought down to 65 bags to evenly hold all of the bars.

A line has a slope of 3/5. It passes through the points (1, 2) and ( k, 8). What is the value of k?
A. 7
B. 11
C. 8
D. 15
Answer:
B. 11
Step-by-step explanation:
Delta y over delta x
(8-2)/(k-1) = 3/5
6/(k-1) =3/5
6 = 3/5k - 3/5
6 3/5 = 3/5k

Sal is tiling his entryway. The floor plan is drawn on a unit grid. Each unit length represents 1 foot. Tile costs $1.55 per square foot. How much will Sal pay to tile his entryway? Round your answer to the nearest cent. (hundredths place)
Answer:
He'll pay $110.25
Step-by-step explanation:
To find the area, we divide the shape into two parts at approximately the middle line. The top shape is a trapezoid of base length 7 feet and height 6 feet, while the bottom shape is a parallelogram with one side equal to 4 feet.
Area of trapezoid = (7 + 4)/2 x 6
Area of trapezoid = 33 sq ft
Area of parallelogram = 4 x 4
Area of parallelogram = 16 sq ft
Total area = 49 sq ft
Cost = 2.25 x 49
Cost = $110.25

Hakeem went shopping for a new pair of sneakers because of a sale. The store was offering a 40% discount. What number should he multiply the prices on the tags by to find the price he would have to pay, before tax, in one step?
Answer: 60% or 0.6
Step-by-step explanation:
A discount simply means the amount that is deducted from the normal cost of a good or service.
In the question above, the store was offering 40% as discount, this means that he'll only pay 60% of the price of the good. Note that (100% - 40% = 60%).
Therefore, the number that he should multiply the prices on the tags by to find the price he would have to pay will be 60% = 0.6.
evaluate functions from their graph g(7)
Answer:
Evaluate functions from their graph g(7)= 4
Step-by-step explanation:
If the point (a,b)(a,b)left parenthesis, a, comma, b, right parenthesis is on the graph, then g(a)=bg(a)=bg, left parenthesis, a, right parenthesis, equals, b.
We should look for the point on the graph whose x-coordinate is 7.
The point on the graph whose xxx-coordinate is 7 is the point (7,4)
Therefore, g(7)=4.

Somebody pls!! “Write the equation of the line in fully simplified slope-
intercept form.”
Answer:
y = 3/5x + 5
Step-by-step explanation:
Slope-intercept form is y = mx + b where m is the slope (rise / run of the line) and b is y-intercept (y value of where the line intersects with the y-axis.
The line is rising up 3 and run to the right 5 and so it's slope is 3/5. The line intersects with the y-axis at a y value of 5 and so it's y-intercept is 5.
Therefore, your answer in slope-intercept form is y = 3/5x + 5.
