The area of a parking lot is 600 square meters. A car requires 6 square metes and a bus requires 30

1 answer:

4 0

A=600 with a maximum of 60 vehicles
Each car takes up 6 m
Each bus takes up 30 m

Max amount of cars in the lot would be 600 divided by 6 or 100 cars.

Max amount of buses in the lot would be 600 divides by 30 or 20 buses.

To collect the maximum amount of money using only 60 vehicles, park 20 buses and 40 cars.

In each part, a and b represent the length of a leg of a right triangle, and c represents the length of its hypotenuse. Find the

Pie

Answer:

c=13 and a=20

Step-by-step explanation:

Here you need to use the Pythagoras theorem :

c²=a² + b²

c = √a² + b²

c = √(12)²+(5)²

c= √144+25

c = √169

c = 13

2) c²=a²+b²

b= √c²-b²

b= √(29)²-(21)²

b = √400

b = 20

In 2 you change your formula just so that it can be easier and just calculate your length straight forward but you can also just do it in the original equation

If f(x) = negative 3X -2, what if f(-5)?

Scrat [10]

Answer:

f(- 5) = 13

Step-by-step explanation:

Substitute x = - 5 into f(x)

f(x) = - 3x - 2 , then

f(- 5) = - 3(- 5) - 2 = 15 - 2 = 13

A water balloon is 5 feet above the ground when Sally launches it into the air. Use the quadratic equation 0 = -t^2 + 4t + 5 to

rodikova [14]

Answer:

$t=5\ sec$

Step-by-step explanation:

we have

$-t^{2} +4t+5=0$

Solve the quadratic equation to find the zero's or x-intercepts

Remember that

The x-intercepts are the values of x when the value of y is equal to zero ( water balloon reach the ground)

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$-t^{2} +4t+5=0$

$a=-1\\b=4\\c=5$

substitute in the formula

$t=\frac{-4(+/-)\sqrt{4^{2}-4(-1)(5)}} {2(-1)}$

$t=\frac{-4(+/-)\sqrt{36}} {-2}$

$t=\frac{-4(+/-)6} {-2}$

$t=\frac{-4(+)6} {-2}=-1$

$t=\frac{-4(-)6} {-2}=5$

therefore

the solution is $t=5\ sec$

Nolan Walker decided to buy a used snowmobile since his credit union was offering such low interest rates. He borrowed $2,700 at

stealth61 [152]

Using the formula for simple interest, it is found that he paid $119.87 in interest.

The<u> simple interest formula</u> is given by:

$E = PIt$

E is the amount of interest earned.
P is the principal(the amount of money invested).
I is the interest rate(yearly, as a decimal).
t is the time, in years.

In this problem:

Borrowed $2,700, thus $P = 2700$
Interest rate of 3.5%, thus $I = 0.035$
From December 26, 2019 to February 21, 2021, there were 423 days, thus the time in years is $t = \frac{423}{365} = 1.2685$

Thus, the interest paid was of:

$E = PIt = 2700(0.035)(1.2685) = 119.87$

$119.87.
