Answer:
h = (3×V)/ (pi×r²)
Step-by-step explanation:
[tex]v = \frac{\pi {r}^{2} h}{3} [/tex]
[tex]3 \times v = \pi {r}^{2} h[/tex]
[tex]h = \frac{3v}{\pi {r}^{2} } [/tex]

calculate the length of the legs of an isosceles triangle.The base is less than the other congruent legs by two units.The perimeter of the triangle is 22 meter .
Answer:
Sides = 8 each and base = 6
Step-by-step explanation:
Let congruent legs = x, then the base is x - 2 so,
P = x + x + (x - 2)
22 = 3x - 2
24 = 3x
8 = x (sides)
base = 8 - 2 = 6
Someone answer ASAP no image explanations please I can't see those!
Answer: The side length is 3in (inches)
Step-by-step explanation:
Since it's a cube, all the sides are the same.
Formula for cube: L x W x H

Find the area of the triangle.
A. 5.7 ft
B. 8 ft
C.0.1 ft
D. 16 ft
Answer:
formular 1/2 × base × height
1/2 × 2 × 8
16/2 = 8 ft
ans 8 ft
Answer:
Step-by-step explanation:
a = 2 ft ; b = 8 ft ; C = 91
[tex]Area = \dfrac{abSin \ C}{2}\\\\ =\dfrac{2*8*Sin \ 91}{2}\\\\=8* 0.99\\\\= 7.92\\\\= 8 \ ft^{2}[/tex]

Answer:
[tex]8 + x = 2 + 8 \\ 8 + x = 10 \\ x = 10- 8 \\ \\ x = 2 \\ then8 + 2 = 2 + 8 \\ thank \: you[/tex]
Answer:
2
Step-by-step explanation:
8 + 2 = 10, so basically, 10 - 8 = 2. Meaning the missing number to when 8 is added to something to equal 10, would be 2.
Given g(x) = -5x + 5, solve for 2 when g(x) = 0.
Answer:
Step-by-step explanation:
g(x) = 0
0=-5x+5
5x=5
x=1
Answer:
x = 5
Step-by-step explanation:
given:
[tex]g(x) = -5x + 5[/tex]
solve for x, when:
[tex]g(x) = 0[/tex]
replace x with 0
~~~~~~~~~~~~
➡️ [tex] x = -5(0) + 5 [/tex]
➡️ [tex] x = 0 + 5[/tex]
➡️ [tex]x = 5 [/tex]
Three consecutive vertices of a parallelogram are (– 2, 1); (1, 0) and (4, 3). Find the coordinate of the fourth vertex and find the area of the parallelogram.
Answer:
D(1,4) - the fourth vertex, the area is equal to 12
Step-by-step explanation:
A(2,-1), B(1,0),C(4,3), They are consecutive, we need to find the point D, find the midpoint of AC (O)
xo= (xA+xc)/2 x0= (-2+4)/2=1
y0=(yA+yC)/2 y0= (1+3)/2=2
0(1,2)
O is the midpoint of BD, so let's find the vertex D
X0= (xB+xD)/2 1= (1+xD)/2 xD=1
y0= (yB+yD)/2 2= (0+yD)/2 yD=4
D(1,4)
the vector DA is (-2-1, 1-4)= (-3,-3)
the vector DC is (4-1, 3-4)= (3,-1)
The modul of DC is sqrt ((-3)^2+(-3)^2)= 3*sqrt2(the length of the side Dc)
The modul of DA is sqrt (3^2+(-1)^2)= sqrt10(the length of the side DA)
cosD= (-3*3+(-3)(-1))/3*sqrt2*sqrt10=-6/3*2*sqrt5=-1/sqrt5
sinD= sqrt (1- 1/5)=2/ sqrt5
S=3sqrt2*sqrt10*2/sqrt5= 12
5 quarters weigh approximately 1 ounce. How many ounceswould you expect a collection of quarters worth $15 to weigh?
5 quarters =1.25$
15$÷1.25$=12
then 15$ in quaters would weigh 12 ounces

4 + (-11)
4 (+ × -) 11
4 - 11
- 7
Therefore the answer is -7
Answer:
4 + (-3-8)
4 + (-11)
4 (+ × -) 11
4 - 11
- 7
Therefore the answer is -7

HELP ILL GIVE BRAINLIEST QUICK!!
Answer:
Dan is correct
Step-by-step explanation:
First, I calculated the amount of hours that the graph shows in total, coming up with a total of 3,085 hours. I do this by multiplying the number of adults surveyed by the number of hours they spent. So for the first column, (80+70)*1, second column, (90+80)*2, third column, (135+130)*3, fourth column, (140+135)*4, and fifth column, (65+75)*5 if you get what I mean. Then I add up all values. Knowing that there were two sets of 500 American adults interviewed already, I came to the conclusion that 1,000 total adults were surveyed. Finally, I divided the total number of hours(3,085) by the total number of adults interviewed (1,000) to get a mean of 3.085 hours, rounding it to 3 hours and proving that Dan is correct.

B) 74
Step-by-step explanation:
This is an icoseles triangle because of the 2 lines in each side. This makes <Y equal to <Z
Given:
<Y = <Z
All triangle angles add up to 180 so:
<W + <Y + <Z = 180
<W + 53 + 53 = 180
<W + 106 = 180
<W = 180 - 106
<W = 74
