Answer:
Step-by-step explanation:
Surface area of cube = 10848 square cm
6a² = 10848
Divide both sides by 6
a² = 10848/6
a² = 1808
a = √1808
a = 42.52 cm

A rectangle has a length that is 9 inches less than twice its width. The area of the rectangle is 180 square inches.
a. Write an equation that represents the situation.
b. Find the length and width of the rectangle.
c. Find the perimeter of the rectangle.
pls help lols
Answer:
Step-by-step explanation:
a) Let the width = w
Two times its width = 2*w = 2w
9 inches less than 2w = 2w - 9
Length = 2w - 9
Area of rectangle = length *width = 180 square inches
(2w - 9 ) * w = 180
2w*w - 9*w = 180
2w² - 9w - 180 = 0
b) sum = -9
Product= -360
Factors = -24 , 15 {15 *[-24] = -360 and 15 + (-24) = -9 }
2w² - 9w - 180 = 0
2w² - 24w + 15w - 180 = 0
2w(w - 12w) + 15(w - 12) = 0
(w -12) (2w + 15) = 0
{Ignore 2w + 15 = 0 as measurements cannot be a -ve value}
w - 12 = 0
w = 12 inches
l = 2w -9
= 2*12 - 9
= 24 - 9
l = 15
length = 15 inches
Width = 12 inches
c) Perimeter = 2 *(length + width)
= 2*(15 + 12)
= 2 * 27
= 54 inches

If x < 0 and y < 0, where is the point (x, y) located?
Answer:
Step-by-step explanation:
You could do negative numbers because no positive number is less than 0, as you know.
So, it would have to be a negative one because they are to the left of zero on a number line, meaning less than. A positive number on a number line is usually to the right of zero, meaning more than.
For instance, x could equal -1 and y could equal -4.
It would be in Quadrant 3.

Answer:
1. 108.375 2. 76.765625
Step-by-step explanation:
1. We have the s-value now, which is 4.25.
Plug it in to the equation for surface area:
6*(4.25)^2
6*4.25*4.25
Using a calculator, we get 108.375
2. Plug 4.25 in to the equation for volume:
(4.25)^3
4.25*4.25*4.25
Using a calculator, we get 76.765625
What type of function is described by the equation y=3+x?
Use what you know about transformations of the quadratic functions. How would the equation of an exponential function change to have an x-intercept? Write an example of an exponential function with an x-intercept. Explain your reasoning.
A. If a negative number were subtracted from the exponential function it would move down the y-axis creating an x-intercept; y = 3 • 2^x − (−5).
B. If a number were added to the exponential function it would move up the y-axis creating an x-intercept; y = 3 • 2^x + 5.
C. If a number were added to the exponential function it would move down the y-axis creating an x-intercept; y = 3 • 2^x + 5.
D. If a positive number were subtracted from the exponential function it would move down the y-axis creating an x-intercept; y = 3 • 2^x − 5.
Answer:
D. If a positive number were subtracted from the exponential function it would move down the y-axis creating an x-intercept; y = 3 • 2^x −5.

Nick had 14 jelly beans in a bag. His mother put a handful of jelly beans in the bag. When Nick counts his jelly beans, he discovers he now has 28 of them. Which of the following equations will help Nick solve for the number of jelly beans, j, that his mom put in the bag?
14j = 28
14 + 28 = j
14 + j = 28
j − 14 = 28
Answer:
14 + j = 28

Answer: A) The relationship is proportional because the ratio of m to k is constant.
______________________________________________________
Step-by-step explanation:
17.699 ÷ 11 = 1.609
41.834 ÷ 26 = 1.609
&
54.706 ÷ 34 = 1.609
______________________________________________________
The three equations above equal 1.609 making the relationship between m & k constant.
If you were to plot these coordinates on a graph you would see a straight line.
The dataset below has an outlier. First, determine the outlier. If the outlier is excluded how does it affect the mode?
12, 19, 19, 20, 21, 22, 22, 23, 24, 26, 27, 28, 29, 30, 32, 35, 48
A. The outlier is 48 and it decreases the mode if it is excluded.
B. The outlier is 12 and it increases the mode if it is excluded.
C. The outlier is 12 and it has no effect on the mode if it is excluded.
D. The outlier is 48 and it has no effect on the mode if it excluded.
the answer is C because if we get rid of 12 it will have no effect on the mode and it will not change mode. the mode will remain the same.
if I helped mark me the brainest!!
Answer:
D
Step-by-step explanation:
D. because 48 is much bigger than the other numbers and 12 isn't that much smaller that 19 that 48 is bigger than 35 and because there is only one 48 it won't affect the mode
The mode is 19 or/and 22
A study shows that as the temperature decreases, the electric bill increases. Which graph best represents this situation?
Answer:
The only graph whose line is strait
Step-by-step explanation:
This graph represents the situation because energy bills will have a set amount of money which directly correlates with the amount of energy you use. When it gets cold you use more energy to keep you warm. As you use more energy your price rises at the same pace-thus a strait line.

Answer:
Hi, there your answer will be y=2x-4
Step-by-step explanation:
Well finding the y-intercept you have to see what goes through the y-axis in this case it is -4
To find the slope you can do [tex]\frac{rise}{run}[/tex]
or you can use the slope formula which is
[tex]\frac{y2-y1}{x2-x1}[/tex]
In this case, I'll be using the slope formula I'll pick two coordinate which are (0,-4) and (3,2). I'll be plugging that in
[tex]\frac{2-(-4)}{3-0}[/tex]=[tex]\frac{6}{3}[/tex]
We will simplify [tex]\frac{6}{3}[/tex] which will equal to 2

Can someone tell me where to put the points
Answer:
points at (2,6) (3,9) (7,21) (8,24)
Step-by-step explanation:
Answer:
..
Step-by-step explanation:
each line is 1, so in between 0 and 5, the numbers 1-4 are there.
Coordinate place (x,y), the x is the horizontal or just the one going left and right. Y places are the numbers going up and down.
Take (2,6), we go to the origin (0,0) and we go 2 to the right since its in the x place, then we go from the point where we moved and go up 6 since its a y.
does that make sense?

A. 2,956.5 square meters
B. 2,250 square meters
C. 3,309.75 square meters
D. 2,826 square meters
Answer:
A
Step-by-step explanation:
πr^2
π * 15^2 = 706.858347
75 X 30 = 2250
706.858347 + 2250 = 2956.858347
The total area enclosed by the track is 2956.5 square meters
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The given figure has one rectangle and two semicircles
The area of rectangle is length times width
Area = length × width
=75×30
=2250 square metres
Area of circle is πr²/2
=3.14×15²/2
=706.5/2
=353.25
As there are two semicircles = 2×353.25
=706.5
Total area is 2250+706.5 which is 2956.5 square meters
Hence, the total area enclosed by the track is 2956.5 square meters
