Answer:
$185 = ($35.25 * P) + ($7.50 * r)
Step-by-step explanation:
If the total that the customer paid was $185 this means that the equation must equal $185. The equation itself must be the number of gallons of exterior paint (P) that the customer ordered multiplied by the price per gallon ($36.25), which is then added to the product of the number of rollers the customer ordered (r) and the price per roller ($7.50). This together would form the following equation...
$185 = ($35.25 * P) + ($7.50 * r)

Answer:
The area of ∆DEF = 4.5in²
Step-by-step explanation:
From the above diagram,
∆BAC ~∆DEF
It is important to note that if two triangles are similar, the ratio of their areas is equal or equivalent to the ratio of the areas of their sides
This means for the above question, that
We have the bigger triangle = ∆BAC has a side of 4 in and Area = 8 in²
The small triangle has a side of 3in
Finding the scale factor k = ratio of the sides of both Triangles
k = 4/3
k² = (4/3)²
k² = 16/9
Hence,
Area of ∆BAC/ Area of ∆DEF = 16/9
8in²/Area of ∆DEF = 16/9
We cross Multiply
8 in² × 9 = Area of ∆DEF × 16
Divide both sides by 16
Area of ∆DEF = 72/16
= 4.5in²
Therefore, the Area of ∆DEF rounded to the nearest tenth = 4.5in²
1 kilogram= 1,000 grams
2 kilograms= 2,000 grams
1,000/2=500
2,000+500=2,500 grams
2.5 kilograms= 2,500 grams.
Hope this helps!! :)
