A community swimming pool has a deep end and a shallow end. The volume of water in the deep end can be represented by (2x2+12x+10) ft3 and the volume of the water in the shallow end can be represented by (4x2−100)ft3.
Write two different equivalent expressions ("simplified" and "simplified") that represents the total volume of the water in the pool in ft3.
Answer:
(2x2+12x+10) = (4x+12x+10) = (16x+10) ft³
(4x2−100) = (8x-100) ft³
(8x-100 + 16x+10 + x) > (24x-90)(8x-100 + 16x+10 - x) < (24x-90)Question 3: What is the volume of corn held in this cone-shaped grain silo? 1 point
Use 3.14 for Pi and round to the nearest cubic foot (whole number). *
15 yd
20 yd
Nour answer I
Answer:
4,712 yards.
We can use the formula V=1/3hπr² to figure out what the volume of the cone is.
So using the numbers provided the new equation would be V=1/3(20)π15², which would come out to 4,712 yards.
Halind bought a hot dog for $4. He also bought a some
bottles of water for $2 each. Halind did not spend more
than $15 on the hot dog and waters. Which inequality can
be used to find w, the number of waters that Halind
bought?
A. 2W - 4 = 15
B. 2w + 4 > 15
C. 2W - 4 > 15
D. 2w + 4 < 15
Answer:
b
Step-by-step explanation:
your adding 2 and 4 together and the question also states that they didn't spend more than $15 so...
2w + 4 is less than $15
he pentagon ABCDE is graphed on a coordinate plane with vertices A(0, 0), B(3, 5), C(3, 8), D(8, 5), and E(8, 0). What is the pentagon's perimeter?
A) 27.6 units
B) 16.0 units
C) 32.4 units
D) 24.0 units
Answer:
I think the coordnates are incorrect because they do not make a pentagon when graphed. Could you please check and make sure those are right.
Step-by-step explanation:
But to do the question, you graph the points and then use the distance formula to find the side lengh of each side. Then simply just add them together. Also if you don't want to draw out a coordnate plane, you can use Desmos, an online graphing calculator.

5.The measure of smaller angle is 87 degrees.
Step-by-step explanation:
Consider the provided information.
The provided angles are 3x degree and 2x + 25 degree.
Two angles are said to be Supplementary angles if their sum is 180 degree.
It is given that the provided angle are supplementary angles, thus
3x + 2x + 25 = 180
5x + 25 = 180
5x = 180 - 25
5x = 155
x = 31
Now, substitute the value of x in first angle i.e 3x.
3(31) = 93
Substitute the value of x in the second angle i.e 2x + 25
2(31) + 25 = 62 + 25 = 87
Hence, the measure of smaller angle is 87 degrees.

Is a quadrilateral with 2 pairs of parallel sides a rhombus? Why or why not?
HELP ASAP ITS MATH!!!
Answer:
90
Step-by-step explanation:
Since the actual length is 120. You divide the 120 by 24 which is 5. So, you multiply 18 x 5, which results in the answer being 90!

Find the values of x, y, and z for which ABCD must be a parallelogram.
I tried this one but i don't think i am correct on it
Answer:
A. x = 50, y = 130, z = 130
Step-by-step explanation:
50 and z are adjacent angles,
Sum of adjacent angles = 180,
50 + z = 180
z = 180 - 50
z = 130
z and x are adjacent angles,
Sum of adjacent angles = 180,
x + z = 180
130 + x = 180
x = 180 - 130
x = 50
z and y are opposite angles,
Opposite angles are equal in a parallelogram,
z = y = 130
Sunscreen is priced at $10.00 per bottle, plus 8% tax. If Sonya purchases a bottle of sunscreen with a $20.00 bill, then what is her change?
Percent Proportion
Answer:
$9.20
Step-by-step explanation:
the tax would be $0.80 because 8% of $10 is $0.80
so the total cost is $10.80
now subtract that by her $20 bill
20-10.80= 9.20
so she will be given $9.20 back in change
hope this helps luv <3
Answer:
$9.20
Step-by-step explanation:
d/10=8/100
10×8=80
dx100=100d
80=100d
80÷100=0.8
100d÷100=d
d=0.8
10.80-20.00=9.20
hope this helps

The dot plot shows the ages of soloists in a orchestra. Answer the following questions below.
A. Is the mean, median or model the best measure of center for this data?
B. Find the measure of center you chose for part A.
C. Does the data have an outlier? (Answer Yes or No)
D. Is the data skewed? If so, is it skewed right or skewed left? (Answer Left or Right or Not Skewed)
Answer:
Data set = 12,14,28,28,30,30,32,32,32,32,34,34,34,36,36,36,36,36,38,38
A.) Median
B.) Median = 33
C.) Yes, Outliers: 12 and 14
D.) Skewed left
Step-by-step explanation:
Outliers: Points in the data set that are either way too small or way too big than other numbers in the data set.
Skewed: A sudden change in the data set going away from the data set:
Skewed right: If most of the data are on the left side of the histogram but a few larger values are on the right, the data are said to be skewed to the right.
Skewed left: If most of the data are on the right, with a few smaller values showing up on the left side of the histogram, the data are skewed to the left.
Not Skewed: If the data are symmetric, they have about the same shape on either side of the middle.

Find the missing side. Round to the nearest tenth when necessary.
Answer:
15.6
Step-by-step explanation:
Because it is a right triangle, you can use the Pythagorean Theorem. The theorem is c^2 = a^2 + b^2, with c being the hypotenuse, and a and b being the legs. So plug in the values and you will get 18^2=9^2 + b^2. Solve for b and you will get 15.6.
Answer:
x=15.59
Step-by-step explanation:
using the pythagorean theorem we know a²+b²=c²
also that c²-a²=b². in this case we're using the second one. c² is 18², and a² is 9². 18²-9² is 243. we then find the square root of that number to get x (b²). x=15.59 rounded to the nearest hundreth.
1. Two of the angles of a triangle measure 15° and 150°. Classify the triangle.
A. Equilateral
B. Scalene
C. Isosceles
Its Isosceles
cause a triangle must always add up to 180 if you are finding the angles and they give you 15 and 150 if you add that you get 165 and i you subtract that from 180 you get 15 and a isosceles has 2 equal angles
Answer:
Isosceles
Step-by-step explanation:
An isosceles triangle is a triangle with two equal sides, as well as two equal angles. So take 150, add it to 15. You get 165. Take 180, then subtract 165. You get 15, and since you know another angle is 15, you have an isosceles triangle.
