Turner is training for a triathlon and needs to swim a certain distance for today's workout. If he swims at the rec center pool,

he will complete a 150-meter warmup and then swim laps in a lane that is 30 meters long. If Turner swims at the indoor pool at his gym, he will complete a 250-meter warmup, plus a main set that consists of 20 meters per lap. If Turner swims the correct number of laps, he can complete the same distance in either pool. How many laps will that take?
a
13 LAPS
b
10 LAPS
c

-3x^{2}-21x-54 what are the zeros? (Solutions)
Irina-Kira [14]
The only way to solve if it is equal to something
assuming that the teacher wanted you to make it equal to zero do
0=-3x^2-21x-54

remember if we can do
xy=0 then assume x and y=0

so factor

0=-3x^2-21x-54
undistribute the -3
0=-3(x^2+7x+18)
remember 0 times anything=0 so
x^2+7x+18 must equal zero
use quadratice formula which is

if you have
ax^2+bx+c=0 then
x=\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}

x^2+7x+18
a=1
b=7
c=18

x=\frac{-7+/- \sqrt{7^{2}-4(1)(18)} }{2(1)}
x=\frac{-7+/- \sqrt{49-72} }{2}
x=\frac{-7+/- \sqrt{-23} }{2}
i=√-1
x=\frac{-7+/- i\sqrt{23} }{2}



the zerose would be
x=\frac{-7+ i\sqrt{23} }{2} or \frac{-7- i\sqrt{23} }{2}

Help with this question please!
Anton [14]

∠1 and ∠2 are alternate exterior angles where transversal BE crosses parallel lines AC and DF, therefore they are equal. ∠2 and ∠3 are opposite angles of a parallelogram, therefore they are equal.

... ∠1 = ∠2

... 3x -5 = 2x +15 . . . . substitute the given values

... x = 20 . . . . . . . . . . . add 5-2x

The measures of angles 1, 2, and 3 are 2·20+15 = 55 . . . degrees.

1. The weekly ad for a local grocery store advertises a 5 pound bag of organic apples for $13.95. Round each rate to the nearest
olga_2 [115]

Answer:

a)

$2.79 per pound.

$0.93 per apple.

b)

Unit price per pound is typically used because weight and size of every      apple is not same.

Step-by-step explanation:

5 pound bag of organic apples = $13.95

1 pound bag of organic apples = $13.95/5

                                                   = $2.79

The unit price of apples that cost $13.95 for 5 pounds is $12.79 per pound.

<em>As a general rule, 1 pound of apples is equal to: 4 small apples. 3 medium apples. 2 large apples. So, here we assume that apples are of medium size.</em>

3 apples cost = $2.79

<em>The unit price means 'what is the cost of 1 apple'</em>

1 apple cost    =$2.79/3

                       =$0.93

The unit price of apples that cost $2.79 for 3apples is $0.93 per apple.
