Answer:

1.29x+1.35y≤12

Step-by-step explanation:

The total amount of money spent on apples is: 1.29x

The total amount of money spent on oranges is: 1.35y  

No more than $12 means $12 or less, mathematically: ≤ 12

Combining this, we get: 1.29x+1.35y≤12

Answer:

Option D. 1.29x + 1.35y ≤ 12

Step-by-step explanation:

Nick is making a fruit salad.

He buys apples per pound for = $1.29

He buys oranges per pound for = $1.35

He spend no more than $12.00 or we can say less than equal to $12

Let x represent the number of pounds of apples that Nick buys and y represent the number of pounds of oranges.

Cost of x pounds of apples = $1.29x

Cost of y pounds of oranges = $1.35y

Total cost = 1.29x + 1.35y

Total cost should be less than equal to $12.00

Therefore, inequality will be 1.29x + 1.35y ≤ 12

Option D. is the answer.

A race car driving under the caution flag at 40 feet per second begins to accelerate at a constant rate after the warning flag.
shtirl [24]

Answer:

t = 1.667 s

Step-by-step explanation

The distance traveled since the warning flag in feet is characterized by

d = 30*t^2 + 40*t

Where t is the time in seconds after the car starts accelerating.

We can easily solve this question by plotting the equation using a graphing calculator or plotting tool.

We need to find the time for which the distance d = 150 ft

150 = 30*t^2 + 40*t     , t > =0

We can see that this value in the graph is approximately

t = 1.667 s

We can verify

30*(1.667)^2 + 40*(1.667 ) ≈ 150

Kathy has $50,000 to invest today and would like to determine whether it is realistic for her to achieve her goal of buying a ho
olga_2 [115]

Answer:

a) About 12%

Step-by-step explanation:

We need to find the interest rate required to achieve her goal, so we will need to use the interest-compound formula:

FV=PV(1+i)^{n}

Where:

PV= Present Value

i= interest rate

FV= Future Value

n= number of periods

replacing the data provided:

150.000=50.000(1+i)^{10}

solving for i:

first, divide both sides by 50.000 to simplify the equation:

3=(1+i)^{10}

Take 10^{th} roots of both sides:

1+i=±\sqrt[10]{3}

solve for i:

i=±\sqrt[10]{3} -1

We get two answers, but we look for a coherent value. So we take the positive one:

i=11.6123174≈12
