Answer:

75a + 90b ≤ 70000

a ≤ b

Step-by-step explanation:

Maple grove wants to include 2 types of maple trees .The 2 trees that are to be added cost $75 and $90 each. The total amount should not exceed $70000. And the people wants more of the $90 tree.  

Let

the number of the $75 tree = a

number of the $90 tree = b

The total cost of the $75 variety of maple tree = 75a

The total cost of the $90 variety of maple tree = 90b

And the cost of the trees shouldn't exceed $70000. Therefore,

75a + 90b ≤ 70000

Note the people needs more of the $90 tree, this means a ≤ b.

Serhud [2]

Answer:

24 cars

Step-by-step explanation:

Given

Red:Blue = 3:2

Cars = 40

Required

Determine the number of red cars

Number of red cars is calculated using:

Red\ Cars = \frac{Red\ Ratio}{Total\ Ratio} * Cars

Red\ Cars = \frac{3}{3 + 2} * 40

Red\ Cars = \frac{3}{5} * 40

Red\ Cars = \frac{3 * 40}{5}

Red\ Cars = \frac{120}{5}

Red\ Cars = 24

5/8 of the 64 musicians in a music contest are guitarists. Some of the guitarists play jazz solos, and the rest play classical s
motikmotik

The first thing we must do for this case is find the number of total guitarists.

We have then:

(\frac{5}{8}) * (64) = 40

We now look for the relationship between the number of guitarists playing jazz alone to the total number of guitarists.

We have then:

\frac{x}{40} = \frac{1}{4}

Where,

x: number of guitarists playing jazz alone

From here, we clear the value of x.

x = (\frac{1}{4}) * (40)\\x = 10

Then, the number of guitarists who play classical solo is:

40 - 10 = 30

Answer:

30 guitarists play classical solos in the contest
