Answer:
<em>On day the he covers </em>128.4 ft²
<u>Step-by-step explanation</u>:
Lets first figure out how much he has done so far
To figure out how much he does we can use a proportion
Set up a proportion for first day
2/7 = x/299.6
Solve the proportion
2×299.6÷7 = 599.2/7 = x
x = 85.6
<em>He covered 85.6 sq/ft on day 1</em>
Find day two
85.6 * 2 = 171.2
Find how much is left to do on day 3
299.6-171.2 = 128.4 ft²
She needs 8 serving dishes because you can only make 8 one cup servings out of a half gallon of ice-cream.
A little blurry...but...
3(2x+7)=27 do indicated operations on left side
6x+21=27 subtract 21 from both sides
6x=6 divide both sides by 6
x=1
Answer:
x=75
Step-by-step explanation:
if the polygons are similar
40 30
------- = --------
100 x
using cross products
40x = 30*100
40x =3000
divide by 40
40x/40 = 3000/40
x =75
