Answer:
The ratio of the area of ∆ABC to the area of ∆DEF is 25/36
Step-by-step explanation:
∆ABC ~∆DEF
∆ABC has a heights of 20 inches, and ∆DEF has a height of 24 inches
The ratio of the height (h1) of ∆ABC to the height (h2) of ∆DEF is:
h1 / h2= (20 inches) / (24 inches)
h1 / h2= 20 / 24
Simplifying the fraction dividing the numerator and the denominator by 4:
h1 / h2= (20/4) / (24/4)
h1 / h2= 5 / 6
The ratio of the area (A1) of ∆ABC to the area (A2) of ∆DEF is:
A1 / A2 = (h1 / h2)^2
A1 / A2 = (5 / 6)^2
A1 / A2 = 5^2 / 6^2
A1 / A2 = 25 / 36
Answer:20 pints of blue paint and 8 pints of yellow paint
Step-by-step explanation:
5 pints of blue and 2 pints of yellow make 7 pints of green. (5 + 2 = 7)You must do this four times to get 28 pints of green. (4 · 7 = 28)So you need 20 (4 · 5) pints of blue and 8 (4 · 2) pints of yellow.

Then solve the linear eqn
420 miles/ 12 gallons= 35 miles per gallon
Final answer: 35 miles per gallon
Answer: B
Step-by-step explanation: well by graphing the inequality we know it’s a solid line. There’s shading on the right but if you look closely at (0,0), the shading doesn’t go past or near the origin making it B “Does not include the origin”.
