Answer:
40%
Step-by-step explanation:
just take a number, for example, 1, and do the math.
1 - 30% = 0.7.
1 - 50% = 0.5.
0.7 / 0.5 = 1.4.
thus the answer is 40%.

i need help with #3 & #4
Step-by-step explanation:
Q3, B
Q4, I'm not too sure about this one but I think its D
Pls help and show your work
Answer:
21. Vol. = L ^ 3
or, 27000 = L ^ 3
or, cube root undefr 27000 = L
Therefore, Edge length = 30 cm
22.
a. v = l ^ 3
or, 64000 = l ^ 3
or, cube root under 64000 = L
or, l = 40 cm
Also,
surface area = 6 a ^ 2
= 6 * 40 ^ 2
= 6 * 1600
= 9600 cm ^ 2 #

Explanation:
There's a quick way to answering questions like this without the need to go through the whole process of finding the terms before the
x

term:
Using the
n
C
r
button, the value of
n
represents the expansion power of
9
and the
r
would be the term you want to find, so in this case, it would be

IN PARALLELOGRAM BCHS IF BC = 15, BS = 12, and SH = (3x - 3), WHAT IS THE VALUE OF THE VARIABLE x?
Answer:
6
Step-by-step explanation:
Given a parallelogram BCHS
Opposite side of the parallelogram are equal hence;
BC = HS
Given
BC = 15, BS = 12, and SH = (3x - 3),
15 = 3x-3
3x = 15+3
3x = 18
x = 18/3
x = 6
Hence the value of x is 6

how do I graph this the linear equation is y=2x-3
Answer:
here you go
Step-by-step explanation:
Because you have the x values, all you gotta do now is substitute. so the equation in y=2x-3, you have to substitute the x value of -2---> y=2(-2)-3. Do that for all the values listed and then you have your y values. Use each coordinate pair from the table after and the graph.

Answer:
1: height is 28/3 (9 1/3)
2: Base is 25/2 (12 1/2)
3: Height is 59/4 (14 3/4)
Step-by-step explanation:
Since the formula to find the area of a pallelogram is A=base × height
I divided the area by either the Base or the height (depending which one the problem had gave me)
Therefore 147 will be divided by 15 3/4.
Then 140 5/8 will be divided by 11 1/4.
Finally 151 3/16 would be divided by 10 1/4.

whats greater .12 or 12/16
Answer:
12/16 is greater than 0.12.
Step-by-step explanation:
0.12 = 12/100 = 6/50 = 3/25
12/16 = 3/4.
So, 12/16 is greater than 0.12.
Answer:
12/16 is greater than
12/16 as a decimal would be .75 so its greater than .12
If the diameter of a circle is increased by 6 cm, what is the increase in the circumference of the circle?
Answer:
The circumference will be larger by 3 cm.
Step-by-step explanation:
We know that the circumference of a circle is C = 2πr, where r is the radius. The circumference can also be expressed as C = 2π [tex]\frac{d}{2}[/tex], where d is the diameter (since the radius is half the diameter).
So, if we increase the diameter by 6:
C = 2π [tex]\frac{(d+6)}{2}[/tex]
C = 2π [tex]\frac{d}{2}+\frac{6}{2}[/tex]
C = 2π [tex]\frac{d}{2}[/tex] + 3
If we compare this to the original equation, C = 2π [tex]\frac{d}{2}[/tex], we see that if we increase the diameter by 6 cm, the circumference will be larger by 3 cm.
∠ABC and ∠DBC are complementary angles. If m∠ABC=6x+13 and m∠DBC=4x−3 what is the value of x?
Answer:
x = 8

complementary means add to 90
6x + 13 + 4x - 3 = 90
10x + 10 = 90
10x = 80
x = 8

if the arithmetic mean of 5 and c is 11,what is the value of c?
Answer:
c = 17
Step-by-step explanation:
(c + 5) : 2 = 11
c + 5 = 22
c = 17
If the arithmetic mean of 5 and c is 11, the value of c is 17.
What is the interpretation of average?Arithmetic mean is the best central measure available for representing the values of a data set. It is also called average of the values of the considered data set.
It serves as predicted value(in case no other information of the data is available) of that data set.
Average provides ill information in case of skewed data.
If the arithmetic mean of 5 and c is 11, then the value of c.
(c + 5) : 2 = 11
c + 5 = 22
c = 17
Hence, the value of c is 17.
