Answer:
30 units
Step-by-step explanation:
Make use of the formula for the volume of a sphere. Solve for the radius. (You can solve for the radius before or after you put the numbers in the formula.)
V = (4/3)πr³
36000π = 4/3πr³ . . . . put the numbers in the formula
27000 = r³ . . . . . . . . . multiply both sides by 3/(4π)
30 = r . . . . . . . . . . . . . .take the cube root
The radius of the sphere is 30 units.
Answer:
radius = 30 units
Step-by-step explanation:
The radius of the sphere is 30 units.

Answer:
x = 14
Step-by-step explanation:
(3x + 8) = (4x - 6)
3x + 8 = 4x - 6
+6 +6
3x + 14 = 4x
-3x -3x
14 = 1x
x = 14
plug 14 into the x, then solve it urself
Find the area of a circle whose area equals the half of the sum of the areas of two circles with radil 2 and 3.
13
5
6.5
Step-by-step explanation:
step 1. a circle with r = 2 has area of (pi)r^2 = (pi)(4) = 4pi
step 2. a circle with r = 3 has area of (pi)r^2 = (pi)(9) = 9pi
step 3. the area, A, of a circle is half the sum of the area of the circles with r = 2 and r = 3
step 4. A = (4pi + 9pi)/2 = 13pi/2 = 6.5(pi).
step 5. the answer is not 6.5 but is 6.5(pi) or 6.5 times pi.

Lydia is playing Galaxy 8RX. After three misses, the game is over. Last week, Lydia kept track of how long her games lasted. Hse msde a line plot of her data. Lydia said,"My best time is 2 3/4 minutes longer than my worst time because 4 1/4-1 1/2=2 3/4. Is subtraction the correct operation to compare Lydia's best and worst times?Explain. Are Lydia's calculations accurate?Show how you know. In the line plot, what do the numbers Lydia subtracted represent? Does Lydia's conclusion make sense? How did you decide? If not, what can you do to improve her reasoning?
Answer:
Yes ; Yes ; Yes it makes sense
Step-by-step explanation:
1.) Lydia used subtraction operator to define and establish a relationship between her best and worst game times ; Hence we could conclude that Lydia is correct as this gives the range between both times.
From the numbers given in the question as their is no graph attached :
4 1/4 - 1 1/2
17/4 - 3/2
(17 - 6) / 4
11 /4
= 2 3/4
The subtracted numbers represent the duration of each of the three times game was played ; Hence the numbers represents the game times.
Yes ; Her conclusion makes sense ; as she was able to deduce the range between her best and worst game time
The points (6,6) and (8,h) fall on a line with a slope of
–
3. What is the value of h?
Answer:
h=3
Step-by-step explanation:
(12-6)/(h--5)=3/4 ~ basic slope equation
6/(h+5)=3/4 ~ simplification
24=3(h+5) ~ multiply both sides by (h+5) and 4 to clear the fractions
24=3h+15 ~ distribute the 3
9=3h ~ subtract 15
h=3 ~ divide by 3
Answer:
Step-by-step explanation:
slope = -3
slope = (h-6)/(8-6) = (h-6)/2 = -3
h-6 = -6
h = 0

is -5(x+8) equal to -5x-40 pleaseeee i need helppp
Answer:
yes
Step-by-step explanation:
The distributive property of multiplication over additions is:
a(b + c) = ab + ac
You multiply the number outside the parentheses, the a, by each of the numbers inside the parentheses, the b and the c. Then you add the products.
Now we can do it with your example.
-5(x + 8)
We multiply -5 by x and multiply -5 by 8. Then we add the products and simplify.
-5(x + 8) = -5 * x + (-5) * 8 = -5x + (-40) = -5x - 40

1/3 ( x - 10) = -4 ???
Answer:
[tex]x = - 2[/tex]
Step-by-step explanation:
1) Simplify 1/3 ( x - 10) to x-10/3.
[tex] \frac{x - 10}{3} = - 4[/tex]
2) Multiply both sides by 3.
[tex]x - 10 = - 4 \times 3[/tex]
Simplify 4 × 3 to 12.
[tex]x - 10 = - 12[/tex]
4) Add 10 to both sides.
[tex]x = - 12 + 10[/tex]
5) Simplify -12 + 10 to -2.
[tex]x = - 2[/tex]
So, therefor, the answer is, x = -2.
Maggie made 3kg of fudge. She and her friends ate some and now there are 1 3/4 kg left. How many kg of fudge did maggie and her friends eat?
Answer:
1 1/4 kg
Step-by-step explanation:
Maggie made 3kg of fudge. She and her friends ate some and now there are 1 3/4 kg left. How many kg of fudge did maggie and her friends eat?
The kg of fudge thay maggie and her friends ate is calculated as:
Initial kg of fudge - kg of fudge left
= 3 kg - 1 3/4 kg
3/1 kg - 7/4 kg
Lowest common denominator = 4
= 12 - 7/4 kg
= 5/4 kg
= 1 1/4 kg

the cost of cereal is 35rand for 1 kg , calculate the cost of 25g
Answer:
7.14*10^-4rand
Step-by-step explanation:
If the cost of cereal is 35rand for 1 kg, this can be expressed as;
35 and = 1kg
To get the cost of 25grams, we can write
25g = x
0.025 kg = x
Divide both expressions
35/0.025 = 1/x
35x = 0.025
x = 0.025/35
x = 7.14*10^-4rand
Hence the cost of 25g is 7.14*10^-4rand

Solve for x in the diagram below.
35°
5x°
Answer:
11
Step-by-step explanation:
5x° + 35° = 90°
(complementary angles)
5x° = 90° - 35°
5x° = 55°
x = 55/5
x = 11
Answer:
11
Step-by-step explanation:
35+5x = 90
5x = 90- 35
5x = 55
x = 55/5 = 11
