Answer:
a = 4
Step-by-step explanation:
a^2 + b^2 = c^2
a= ?
b= 3
c= 5 (c is always the hypotenuse)
*plug in given values
a^2 + 3^2 = 5^2
a^2 + 9 = 25
-9 -9
a^2 = 16
*find the square root
sqrt(a) = sqrt(16)
a = 4
Answer:

Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to teh scale factor elevated o the cube
Let
z ----> the scale factor
x ----> the volume of the dilated prism
y ----> the volume of the original prism

we have


substitute

solve for x

<h3>What is common Ratio ?</h3>
In a Geometric Sequence the ratio between each if the consecutive number is called the common Ratio.
Let Yui saving at the end of first month is Rs.x .
As given in the question
each month’s total is 5% greater than the previous month’s total.
Saving after second month is = First Month Total + 5% of First Month Total
= x + (5 % of x )
= x + (5*x/100)
= x + 0.05x
= 1.05x.
Yui balance is 1.05 times of Previous Month balance
Common Ratio = {Next Month }/ {Previous Month}
Common Ratio = 1.05 x / x
Common Ratio = 1.05
Therefore Common Ratio is 1.05 . Option C is the answer.

<span>$40 per hour
15 students per week
Each hourly student earns them $40 and there are 15 students, so this is multiplication.
40 * 15 = 600 per week
There are 4 weeks per month to earn 600 each week, this is again multiplication.
600 * 4 weeks = 2400 per month
</span><span>Out of their earned 2400 they must pay for their overhead, the building rent
2400 - 400 = 2000 profit
They are left with $2000 between them.</span>
Answer: n=4 y=3
Step-by-step explanation:
3n - y = 9
2n + y = 11
n=4
3(4) - y = 9
12 - y = 9
y=3
