Answer: 250 miles

Step-by-step explanation:

I am not sure what grade level you are, but this is how it is done in college.

I hope it can give you an idea and be of some help.

First you have to convert 150 minutes to hours. Then you multiply your new hours to 100 miles.

150 minutes x <u>     1 hour     </u> x<u>       100 miles    </u>= 250 miles

                           60 mins.              1 hour

4x^2+64=0 solve by any method
Rasek [7]

For this case we have the following quadratic equation:

4x ^ 2 + 64 = 0

The solutions are given by:

x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}

Where:

a = 4\\b = 0\\c = 64

Substituting we have:

x = \frac {-0 \pm \sqrt {(0) ^ 2-4 (4) (64)}} {2 (4)}\\x = \frac {\pm \sqrt {0-1024}} {8}\\x = \frac {\pm \sqrt {-1024}} {8}

We have to by definition:

i ^ 2 = -1\\x = \frac {\pm \sqrt {1024i ^ 2}} {8}\\x = \frac {\pm i \sqrt {1024}} {8}\\x = \frac {\pm32i} {8}

We have two roots:

x_ {1} = + \frac {32i} {8} = 4i\\x_ {2} = - \frac {32i} {8} = - 4i

Answer:

We have two complex roots:

x_ {1} - = + 4i\\x_ {2} = - 4i

What is the slope of the line that passes through
Zarrin [17]

Start with the slope formula.

m = y₂ - y₁ / x₂ - x₁

m = -6 - 3 / 5 - -2

m = -9 / 7

So the slope is -9/7.

The breadth of a rectangle is 4 units less than its length. If the perimeter of the rectangle is 20 units, write a pair of linea
Nutka1998 [239]

Answer:

L=7 units and B=3 units

Step-by-step explanation:

L=B+4 ... Equation 1

P = 20

P=2(B+L)... Equation 2

20=2(B+B+4)... Substituting equation 1 to equation 2

20=2(2B+4)

20=4B+8

20-8=4B

12=4B

12/4=4B/4

B=3... Solve for B

L=B+4

L=3+4

L=7... Solve for L

Aiden is visiting the zoo on a field trip. While at the zoo, he sees a 10 foot tall adult elephant standing next to a 15 foot ta
bogdanovich [222]

Set up a ratio:

10 foot tall elephant / X shadow length = 15 foot tall statue / 18 foot shadow.

Cross multiply:

10 * 18 = X * 15

Simplify:

180 = 15x

Divide both sides by 15:

x = 180 / 15

x = 12

The elephants shadow was 12 feet long.
