Answer:
Total income= $1,500
Step-by-step explanation:
Giving the following information:
Groceries spend= $180
It is 12% of the family's income.
<u>To calculate the total income, we need to use the following formula:</u>
Total income= Groceries spend / proportion of income
Total income= 180/0.12
Total income= $1,500
Answer:
24) x = 9.2
25) x = 30.8
Step-by-step explanation:
Given
See attachment for triangles
Solving (24)
To solve for x, we make use of cosine formula
i.e.
cos(40) = adjacent ÷ hypotenuse
So, we have:
cos(40) = x ÷ 12
Multiply both sides by 12
12 cos(40) = x
12 * 0.7660 = x
x = 9.2
Solving (25)
To solve for x, we make use of sine formula
i.e.
sin(25) = opposite ÷ hypotenuse
So, we have:
sin(25) = 13 ÷ x
Multiply both sides by
x sin(25) = 13
Divide by sin(25)
x = 13 ÷ sin(25)
Using a calculator
x = 30.8
Answer:
y=2x+1
Step-by-step explanation:
The diameter of the the circle would be 15.92 mm so if you rounded that up it would 16.
The coordinates would be multiplied by 3, as the scale factor is 3, and it is a dilation, so we know the size increases.
