Answer:
B. (1/2)(2h-8)(h)
Step-by-step explanation:
Area of a triangle = 1/2 × base × height
Let
Height = h
Base = 8 inches less than 2 times wider than the hight
= 2h-8
Substituting the values of base and height into the formula
We have,
Area of a triangle = 1/2 × base × height
= 1/2 × (2h-8) × h
= (1/2)(2h-8)(h)
The correct answer is option
B. (1/2)(2h-8)(h)
Answer:
Babysitting =$8.7
Water park =$8.7
Step-by-step explanation:
In 1 week
Babysitting =3 hrs
Water park = 10 hrs
Total =$ 109
In week 2
Babysitting = 8 hrs
Water park = 12 hrs
Total= $ 177
Both weeks
Babysitting =11 hrs
Water park =22 hrs
Total=$286
33 hrs = $ 286
11 hrs =?
11×286÷33=$95.3
33 hrs = $286
22 hrs = ?
22×286÷33=190.7
Babysitting she got $95.3 in both weeks
Water park she got $190.7(rounded offf)in both weeks
11 hrs = $95.3
1 hr = ?
1×95.3÷11=8.7 (rounded off )
22 hrs = $ 190.7
1 hr = ?
1×190.7÷22= 8.7( rounded off)

Answer:
100 : 250
Step-by-step explanation:
Sum the parts of the ratio, 2 + 5 = 7 parts
Divide the quantity by 7 to find the value of one part of the ratio.
350 ÷ 7 = 50 ← value of 1 part of the ratio, thus
2 parts = 2 × 50 = 100
5 parts = 5 × 50 = 250
350 = 100 : 250 in the ratio 2 : 5
