Answer: 44
Step-by-step explanation:
1/5 of the slab are grey implies that 4/5 are yellow.
The ratio of grey to yellow is thus given as :
1/5 : 4/5
which is 1 : 4
Therefore , the ratio of grey to yellow is 1: 4
The total ratio = 1 + 4 = 5
To calculate the number of yellow , we use the formula
number of yellow = 
X total number of slabs , that is
number of yellow = 
X 55
number of yellow slab = 44
$72 To find out how much the sweater is without 20% off, you need to do this formula:
$60 x 20%
The answer is $12.
So, 20% of $60 is $12.
Now, you need to add 60 and 12 together to get the original sale price.
60 + 12
The answer is 72.
So the original price for the sweater is <span>72 dollars.</span>
Find the percentage of ratio to weight.
180/72 = 2.5
So 2.5 Earth Pounds = 1 Mars Pound
16*2.5 = 40 Pounds the rock weighs on earth.
Answer:
f(x) = 10x + 13
Function f(7) = 83
Step-by-step explanation:
y = 10x + 13
f(x) = 10x + 13
Function f(7) = 10(7) + 13
Function f(7) = 83
