$12.20 to $4.80
A.
60.7% decrease
B.
154.2% decrease
C.
39.3% decrease
Answer: B
Step-by-step explanation:
It just is.
Answer: A. $60.7% decrease
Answer:
= 60.6557% decrease
Step-by-step explanation:
Solution:
Calculate percentage change
from V1 = 12.2 to V2 = 4.8
(V2−V1)|V1|×100
=(4.8−12.2)|12.2|×100
=−7.412.2×100
=−0.606557×100
=−60.6557%change
=60.6557%decrease

10 is a factor and 40 is a multiple of 20 . similarly, 8 is a factor and 96 is a multiple of another number . which of these could be the number ?
Answer:
96
Step-by-step explanation:
Given that:
Number 20 has a factor 10.
Factor means when we multiply it with a number we will get 20.
i.e. when we multiply 20 with 2, we will get 40.
and multiple of 20 is 40
Multiple means, when we multiply 20 with a particular number we will get 40 i.e. when we multiply 20 with 2, we are going to get 40.
To find:
Another number such that 8 is a factor and 96 is a multiple.
Solution:
If we take 4, it can not be the answer because its factor is 2, not 8.
If we take 40, it can not be the answer because its factors are 2, 4, 5, 8, 10 but at the same time 96 is not a multiple of 40.
Let consider 32 now.
32 = 8 [tex]\times[/tex] 4, so 8 is a factor.
Multiples of 32 are 64 and 96.
Therefore, the answer is 96.

Step-by-step explanation:
A tomato is cut into 8 slices. If each slice contains 0.12 grams of fiber, how can rounding be used to estimate the amount of fiber in the entire tomato?
A: Since the slices have about 0.20 grams of fiber each, the amount of fiber in the entire tomato is approximately 8 x 0.20 = 1.60 grams.
B: Since the slices have about 0.20 grams of fiber each, the amount of fiber in the entire tomato is approximately 8 + 0.20 = 8.20 grams.
C: Since the slices have about 0.10 grams of fiber each, the amount of fiber in the entire tomato is approximately 8 x 0.10 = 0.80 grams.
D: Since the slices have about 0.10 grams of fiber each, the amount of fiber in entire tomato is approximately 8 + 0.10 = 8.10 grams.

The expression 12g gives the number of kilometers a car can travel using liters of gasoline.How far can this car travel on 6 1/2 liters of gasoline
Complete question :
The expression 12g gives the number of kilometers a car can travel using g liters of gasoline.How far can this car travel on 6 1/2 liters of gasoline
Answer:
78 km
Step-by-step explanation:
12g = Number of kilometers traveled using g litres of gasoline. - - - (1)
The expression shows that:
Kilometers per gallon = 12
Number of gallons used = miles per gallon * distance
Distance that can be traveled on a 6 1/2 lites of gas :
Here, g = 6 1/2
Substituting the value of g into the expression Given :
Distance = 12g
g = 6 1/2
Distance = 12(6 1/2)
Distance = 12(13/2) = 12(6.5)
Distance = 78 km
Last year Lira earned $12,000 less than her husband Todd. Together they earned $75,000. How much did Lira earn last year?
Given:
Last year Lira earned $12,000 less than her husband Todd.
Together they earned $75,000.
To find:
The amount earned by Lira in last year.
Solution:
Let x be the amount earned by Lira's husband inn last year.
Last year Lira earned $12,000 less than her husband Todd.
Amount earned by Lira = [tex]x-12000[/tex]
Total amount earned by Lira and her husband = [tex]x+(x-12000)[/tex]
= [tex]2x-12000[/tex]
Together they earned $75,000.
[tex]2x-12000=75000[/tex]
[tex]2x=75000+12000[/tex]
[tex]2x=87000[/tex]
[tex]x=\dfrac{87000}{2}[/tex]
[tex]x=43500[/tex]
Now,
Amount earned by Lira = [tex]x-12000[/tex]
= [tex]43500-12000[/tex]
= [tex]31500[/tex]
Therefore, the amount earned by Lira in last year is $31500.

Answer:
53˚
Step-by-step explanation:
There are 360 total degrees in a 4-sided shape (You can find the total number of degrees in a polygon by using the formula 180(n – 2) where n is the number of sides).
so we can add up all the degrees and subtract them from 360.
67 + 135 + 105 = 307
360 - 307 = 53

if x varies inversely with y², and x=10 when y=7. find x when y=10
Answer:
4.9Step-by-step explanation:
Given
x varies inversely with y², then the function is:
x = k/y²x = 10, y = 7, find the value of k by substituting the values of x and y:
10 = k/7²10 = k/49k = 10*49k = 490The function is:
x = 490/y²When y = 10, the value of x is:
x = 490/10² = 490/100 = 4.9Answer:
Statement says that,
x varies inversely with y²
According to the above problem,we get
x=k/y², where k is a constant
Now, x=10 when y=7, so the value of k is
10=k/7²
k=10×7²
k=10×49
k=490
Hence, when y=10,
we have to find the value of x
So by putting the value of k, we get
x=490/(10)²
x=490/100
x=4.9
★ x=4.9 is the right answer.

Liang bought a basket of apples to make pies for her friends. The basket of apples weighed ppp pounds. Before she had time to make the pies, she ate 3 pounds of apples. There are 17 pounds of apples left to make pies.
Write an equation to describe this situation.
What was the total weight of the basket of apples?
Answer:
Equation: p - 3 = 17
Weight of basket of apples = 20 pounds
Step-by-step explanation:
Given that:
Weight of basket of apples = p
Weight of apples eaten by Liang = 3 pounds
Weight of left apples = 17 pounds
According to given statement.
p - 3 = 17
Adding 3 on both sides
p - 3 + 3 = 17 + 3
p = 20 pounds
Hence,
Equation: p - 3 = 17
Weight of basket of apples = 20 pounds
