144 cmStep-by-step explanation:
Given
Radius of a sphere = 3 cmRadius of a cylinder = 5 mm = 0.5 cmVolume of a sphere
V = 4/3πr³= 4/3*3³π = 36π cm³Volume of a cylinder
V = πr²h = π*0.5²h = 0.25πh cm³Comparing volumes to get the length of the wire

Answer:
a^? = 14
Step-by-step explanation:
a^? / a^10 = a^4
is also the same as
a^? - a^10 = a^4 ( due to laws of indices)
a^? = a^4 + a^10
a^? = a^14
the a's striking each other resulting in
? = 14

5.) Write the explicit formula for the arithmetic sequence. -18, -7, 4, 15, 26,...
Answer:
an = -18 +11(n -1)
Step-by-step explanation:
We notice that the first term (a1) is -18, and the common difference (d) is -7-(-18) = 11. Filling these values into the form for the explicit formula gives ...

Which operation should be used to solve x + 7 = 19?
÷ 7
– 7
x 7
+ 7
Answer:-7 is the correct answer.
Solution:Because when we'll use -7 then the 7 in the LHS will get cancelled.
x + 7 = 19
or, x + 7 - 7 = 19 - 7
or, x = 12
Susan enlarged a rectangle with a height of 5 cm and a length of 12 on her computer. the length of the new rectangle is 18 cm. find the height of the new rectangle.
the height of the new rectangle is______cm
Answer:
[tex]\huge\boxed{7.5 \ \text{cm}}[/tex]
Step-by-step explanation:
When we scale a rectangle, we multiply both the length and the width by the scale factor - or a constant value.
We can use a proportion to see how much to multiply by, where we have [tex]\frac{\text{height}}{\text{length}}[/tex].
[tex]\frac{5}{12} = \frac{x}{18}[/tex]
To solve for this proportion, we can cross multiply to find the value of x.
[tex]18 \cdot 5 = 90\\\\90 \div 12 = 7.5[/tex]
Therefore the height of the new rectangle is 7.5 cm.

caitlyn has $210 in her savings account and she has to pay her parents $5 each month.Santos has $90 dollars and he saves $5 dollars each month. At this rate, when will Caitlyn and Santos have the same amount of money ? How much will they each have?
Answer:
After about 12 months both Caitlyn and Santos will have the same balance of 150 dollars in their bank account.
Step-by-step explanation:
Caitlyn's saving: -5x+210
Santos' saving: 5x+90
To know when the total amount in their bank account is the same you would need to make these linear equations equal to one another.
-5x+210 = 5x+90
(Add 5x on both sides)
210=10x+90
(Subtract 90 from both sides)
120=10x
(Simplify)
x=12
After about 12 months their total savings should be the same. To check what their balance will be plug the x value of 12 into both of these equations. This should give 150 as your answer for both equations.
i dont know what is 100x100 is
Answer:
100x100=10,000
A short and easy trick is to multiply only the first number since the rest are zero. So, multiply 1 and 1: 1 x 1. What do you get? 1, of course. Then, add the rest of the zero's after that. In 100, there are two zero's. In 100, there are two zero's. What is two plus two? Well: 2 + 2 = 4 so, four zero's. After that, add the 4 zero's after the 1. One is extremely important in this problem. 1, one zero, 10, two zero's, 100, three zero's, 1,000, and finally, four zero's, 10,000. So, the trick is to multiply the one by the other one, get 1, and add the zero's in the other numbers. This can work as long as it is something like: 10 x 10, 100 x 100, 1,000 x 1,000, or even beyond. Just remember to add the zero's!
Note: This only works with digits similar to the ones listed below.
Notice that they all have a 1 at the front and zero('s) behind them.
1) 10 x 10
2) 100 x 100
3) 1,000 x 1,000
This can continue to over 100 zero's per digit!
The solution to the expression is A = 10000
Given data ,
Let the expression be represented as A
Now , the value of A is
Let the first number be represented as p
The value of p = 100
Let the second number be represented as q
The value of q = 100
So, A = pq
On simplifying the equation , we get
A = p multiplied by the value of q
And , A = 100 x 100
A = 10000
Therefore , the value of A is 10000
Hence , the expression is A = 10000
