A) we have to calculate the areas of the three triangles and the rectangle.
Area triangle=(base x height) / 2
Area (Triangle₁)=(1.5 ft * 1 ft)/2=0.75 ft²
Area (triangle₂)=(2 ft * 1.5 ft)/2=1.5 ft²
Area (triangle₃)=(1 ft * 0.75 ft) / 2=0.375 ft₂

Area rectangle=(base x height=
Area (rectangle)=5 ft * 0.75 ft=3.75 ft₂

Total area=area of the triangles + area of the rectangle.
Total area=(0.75 ft²)+(1.5 ft²)+(0.375 ft²)+(3.75 ft²)=6.375 ft²

solution: 6.375 ft²

b)
Gray paint:
Area of the triangles=(0.75 ft²)+(1.5 ft²)+(0.375 ft²)=2.625 ft²

1/4 gallon------------------45 ft²
x--------------------------2.625 ft²

x=(1/4 gallon * 2.625 ft²)/ 45 ft²=0.01458... gallons

Two hands=2*(0.01458 gallons)=0.029 gallons≈0.03 gallons.


black paint:
Area of rectangle=3.75 ft²

1/4 gallons---------45 ft²
x------------------3.75 ft²

x=(1/4 gallons * 3.75 ft²) / 45 ft²=0.0208...gallons

two hands=2*(0.0208 gallons)=0.04166 gallons≈0.04 gallons

LetterA) \frac{1}{2}(1.5 ft)(1 ft) + \frac{1}{2}(2 ft)(1.5 ft) + \frac{1}{2}(1 ft)(0.75 ft) + (0.75 ft) (5 ft) = 0.75 ft² + 1.5 ft² + 0.375 ft² = 6.375 ft² ......... LetterB) pyramid area: 0.75 ft² + 1.5 ft² + 0.375 ft² = 2.625 ft² ......... pyramid paint: 2 (2.625 ft²) ( \frac{1 quart}{45 ft^2} ) = 0.12 quart ......... base area: 3.75 ft²; base paint: 2 (3.75 ft²) ( \frac{1 quart}{45 ft^2} ) = 0.17 quart

HELP I NEED HELP FAST. ILL MARK YOU BRAINLIEST.
Romashka-Z-Leto [24]

She plays soccer and golf for a total of 125 minutes:

s + g = 125

She plays soccer 45 minutes more than she plays golf:

s = g + 45 this is for A

B= 40 minutes of golf everyday

C= Yes, because in fact, she plays 85 minutes of soccer everyday, and 85 is greater than 80, so yes she CAN play 80 minutes of soccer every day. Perhaps they meant possible to spend ONLY 80 minutes, then NO, that wouldn't be possible, because then by playing 45 minutes more soccer than golf, she wouldn't have played enough to have 125 total minutes of total play. Technically the way the question is worded, the answer is yes.

I hope this helps!

Afina-wow [57]
The equation is 5c+25b=260 when c+b=12. rearrange that into 12-b=c. substitute and you get 5(12-b)+25b=260. b=10. 12-10=2, so 10 buses and 2 cars were used as transportation for the field trip.
