Lola is saving money for a new bike. The first month, she saves $50 from her birthday. Lola plans to save $10 per month thereaft
weqwewe [10]
So this can be translated like the following:
Bike costs= 173 dollars She currently has 107. She saves 11 dollar per week to get the bike so the formula is:
173 = 107 + 11X where X is the number of weeks

Step 1: bring the 107 to the other side to get 173-107 = 11X
Step 2: divide both sides by 11 to solve for X to get this (173-107 )/11 = X
Step 3: Calculate and simplify 66 / 11 = X which is the same as X= 6

So the answer is it will take jennifier 6 weeks to save for the bike.

A band consists of 3 woodwinds for every 7 members of the band. The independent quantity represents the total members of the ban
IgorC [24]

Answer: k=\frac{3}{7}

Step-by-step explanation:

For this exercise it is important to remember the following:

The constant of proportionality, which is represented as "k", describe  the constant ratio of two quantities that are proportional (the independent and dependent variables).

In this case we know that the independent quantity represents the total members of the band and the dependent quantity represents the woodwind members of the band.

Since the band consists of 3 woodwinds for every 7 members of the band, we can conclude that the constant of  proportionality for this relationship is:

k=\frac{3}{7}

The area for a trapezoid is given by the formula below, where a and b are the lengths of the two bases and h is the height of th
aivan3 [116]

Answer:

C

Step-by-step explanation:

Given

A = \frac{h(a + b)}{2}

Substitute the given values with h = a, then

16.5 = \frac{a(a+8)}{2} ( multiply both sides by 2 )

33 = a(a + 8) ← distribute

33 = a² + 8a ( subtract 33 from both sides )

0 = a² + 8a - 33 ← in standard form

0 = (a + 11)(a - 3) ← in factored form

Equate each factor to zero and solve for a

a + 11 = 0 ⇒ a = - 11

a - 3 = 0 ⇒ a = 3

However, a > 0 thus a = 3

Hence the height is 3 feet
