Solving process:
1. Plug numbers into formula with their corresponding variable.
V=(1/3)Bh
216=(1/3)(36)h
2. Multiply 1/3 and 36.
216=12h
3. Divide 216 by twelve.
18=h
4. The height is 18 cm.
Each card she sells cost $3.25.
y = 3.25s
y = 3.25(4) = 13
Each card she buys cost $5.50.
y = 5.25b
y = 5.25(7) = 38.5
She spent 38.5 dollars in total. However, you need to subtract the money she earned by the total cost.
38.5 - 13 = 25.5
She paid 25.5 dollars out of her own pocket, including the money she earned from selling cards she paid 38.5 dollars.
So the answer is "She spent $25.50"
Let me know if it's correct
Answer:
c.132
Step-by-step explanation:
so we are given the diameter which is 42m **the diameter is the straight line that passes through the middle of the circle**
but in order to find the circumference we need to find the radius **the radius is always half (1/2,0.5) of the diameter**
so we have to divide 42/2 which equals 21
now we need to set up the formula;
c=2πr/c=2xπxr **when unknown variables such as 'r' are next to another mathematical numeral such as the pi symbol you don't really have to but the multiplication symbol between them**
c=2π21
=131.946891451
and in your case, it seems we must round to the tenths place so the nine then "becomes a ten" and you're left with 132
good luck :)
i hope this helps
have a good one !!
Answer:
what if my moms a chicken?
Step-by-step explanation:
asking for a friend
The volume of pyramid B is 8 times bigger than pyramid A given that both are square pyramid, where pyramid A is with a base side length of 12 inches and a height of 8 inches and pyramid B is with a base side length of 24 inches and a height of 16 inches. This can be obtained by finding volume of both pyramid and dividing both values.
<h3>How many times bigger is the volume of pyramid B than pyramid A?</h3>
Given that,
Base side length = 12 inches
Height = 8 inches
Base side length = 24 inches
Height = 16 inches
- Volume of a square pyramid = a²h/3, where a is base side length, h is height of the square pyramid.
pyramid A volume = 12² × 8/3 = 384 in³
pyramid B volume = 24² × 16/3 = 3072 in³
The ratio of the two pyramids,
V(B)/V(A) = 3072/384 = 8
⇒V(B) = 8V(A)
Hence the volume of pyramid B is 8 times bigger than pyramid A given that both are square pyramid.
