Answer:
40217.6 cubic feet
Step-by-step explanation:
Given data
Diameter= 40feet
Radius= 20feet
Height=32feet
The expression for the volume is given as
V= πr^2h
Substitute
V= 3.142*20^2*32
V= 3.142*400*32
V=40217.6 cubic feet
Hence the volume of the tank is 40217.6 cubic feet

go to the picture okay
Answer: 7
Step-by-step explanation:
2x(3x-5) -3(x-3)2(2)(3(2)-5) -3(2-3) First you substitute 2 for all the x's. The twos in . parentheses represent multiplication.4(6-5) -3(2-3) Second, you multiply 2 by 2, which equals 4, . and multiply 3 by 2, which equals 6. 4(1) -3(-1) Next, you solve the problems in the . parentheses, which is 6 minus 5 is 1, and 2 . minus 3 is -14-(-3) Next, you multiply 4 by 1, which is 4, and . multiply 3 by -1.4+3 Since two negatives make a positive, the . equation changes to 4 plus 3.7 Finally, you add 4 plus 3 and get 7.P.S: Sorry about the random periods. I had to put them in to format it like that.

Answer:2.3
Step-by-step explanation:
Cut the the shape into a right triangle and a rectangle
Tri: find measure of the base
sin(45)= opp/hyp
= x/1.8
1.8 *sin (45) = x
x = 1.3
base of tri = 1.3
Area of tri = 1/2bh
1/2(1.3)(1.3)
=0.845
Area of rectangle: 1.1*1.3=1.43
Total area = 1.43+0.845
=2.245
=2.3m^2

plz help
Answer:
[tex]\frac{8}{4}[/tex] = 2
Step-by-step explanation:
Divide numerator by denominator
[tex]\frac{10}{4}[/tex] = 2.5 ← not a whole number
[tex]\frac{8}{4}[/tex] = 2 ← a whole number
[tex]\frac{3}{6}[/tex] = 0.5 ← not a whole number
[tex]\frac{7}{8}[/tex] = 0.875 ← not a whole number
What will be the multipicative inverse of 6?
Answer:
1/6
Step-by-step explanation:
The multiplicative inverse of a number is that number as the denominator, and 1 as the numerator. Let's solve this problem using that knowledge.
6 × ? = 1
6 × m = 1
(m stands for multiplicative inverse)
m = 1/6

5) Find the value of x
Answer:
x = 28
Step-by-step explanation:
the angle shown is a right angle
right angle = 90°
•°• (x + 6) + 56 = 90
=> x + 62 = 90
=> x = 90 - 62
=> x = 28Answer:
28
Step-by-step explanation:
5)
(x + 6)° + 56° = 90°
x + 6 + 56 = 90
x + 62 = 90
x = 90 - 62
x = 28
Which is the correct formula for the function?

Answer:
c=10
Step-by-step explanation:
pythagreom theroem
c (hypotenuse) = [tex]\sqrt{a^{2} +b^{2} }[/tex]
plug in values for a and b
c=[tex]\sqrt{6^{2} +8^{2} }[/tex]
c=[tex]\sqrt{36+64\\}[/tex]
c=[tex]\sqrt{100\\}[/tex]
c=10
Answer:
length of the hypotenuse = √100 = 10 ft
Step-by-step explanation:
This is a right triangle with leg lengths 6 and 8 ft. We apply the Pythagorean Theorem a^2 + b^2 = c^2, as follows:
(6 ft)^2 + (8 ft)^2 = c^2
Then c^2 = 100, and c = length of the hypotenuse = √100 = 10 ft
1. Find the median, mode, and mean for, {1, 4, 8, 3, 4, 5, 2, 2, 2, 5}
Answer:
Mean: 3.6
Median: 3.5
Mode: 2
Step-by-step explanation:
Mean: The sum of all numbers divided by the amount of numbers.
Median: The number in the middle.
Mode: the number that is frequently used.
------------------------------------------------------------------------------------------------------
Mean: 1 + 4 + 8 + 3 + 4 + 5 + 2 + 2 + 2 + 5 = 36 ÷ 10 = 3.6
Median: 1, 4, 8, 3, 4, 5, 2, 2, 2, 5. since two numbers are in the middle, we need to add 3 + 4 ÷ 2 = 3.5
Mode: 1, 4, 8, 3, 4, 5, 2, 2, 2, 5. The mode is two because it is used the most.

The length of the longer piece is 124/7.
What is algebra?Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.
let the two pieces be x(longer) and y (shorter)
So,
x+y=31
and, 3x=4y
3x-4y=0
Solving both the equations:
x= 124/7 and y=93/7
Hence, the length of longer piece is 124/7.

A jar contains 3 yellow and 7 green marbles. You randomly draw one marble from the jar then REPLACE it and randomly draw a second marble. Find the probability that you draw a yellow marble first and then a green marble.
3 yellow + 7 green = 10 total marbles.
The probability of picking a certain color is the number of that color over the total quantity.
Picking yellow would be 3 yellow / 10 total = 3/10
Picking green would be 7 green / 10 total = 7/10
To find the probability of doing both multiply the probability of each one by each other:
3/10 x 7/10 = 21/100
The answer would be 21/100

. Is (4,-3) a solution to the following system of equations?
X - y = 4
2x + y = 5
(Use elimination method)
Answer:
No. The correct solution is (3,-1)
Step-by-step explanation:
Since we are using elimination method, we can go ahead and see that we can cancel "-y" from the first equation and "+y" from the second equation.
Once we do that, we go ahead add the like terms and get 3x = 9
Then, we divide by 3 on each side and get x = 3
Now, we can take that value of x and plugin to any of the original 2 equations we started with.
Say we plugin x = 3 into the second equation.. it will turn to, 2(3) + y = 5
Then we solve for y.
2(3) + y = 5
6 + y = 5
6 - 1 = 5
y = -1
There, we found our x value and our y value, (3,-1) :)
