Step 1: Find the total number of laps that Ann and Joe did.

Ann: 21 laps
Joe: 15 laps
Total: 21 laps + 15 laps = 36 laps

Step 2: Multiply each lap swam by $3.

36 x $3 = $108

Their father donated $108.

A woman is standing at the edge of a slow-moving river which is one mile wide, and she wishes to return to her campground on the
vesna_86 [32]

Answer:

the best option would be to swim

Step-by-step explanation:

Hello! To solve this problem we must follow the following steps.

1. remember the concept of uniform motion with constant speed, which establishes the following equation

t=\frac{X}{V}

where

t=time

x=distance

V=speed

2. Calculate the time it takes to swim and calculate the time it takes to walk

walking:

x=10mile

v=5milles/h

t=\frac{10}{5} =2h

swimming

x=1mile

v=3milles/h

t=\frac{1}{3} =0.3h

3. Compare both results and choose the one with the least time.

as you can see it takes less time swimming, so this would be the best way

spayn [35]

Answer:

7°F

Step-by-step explanation:

We have the following information from the question;

Morning temperature = -10°F

Increase in temperate = 17°F

Afternoon temperature = the unknown

Since;

Increase in temperature = Afternoon temperature - morning temperature

Then;

Afternoon temperature = increase in temperature + morning temperature

Afternoon temperature = 17°F + (-10°F)

Afternoon temperature= 7°F

(4w-3)^2<br> what would be the answer to that?? please explain, i’m so confused.
yarga [219]

Answer:

16w^2  - 24w + 9

Step-by-step explanation:

To simplify this, you would use the special product (a - b)^2 = a^2 - 2ab + b^2. We can correlate this with the given term so that,

a = 4w

and

b = 3

Now we just substitute into a^2 - 2ab + b^2

(4w)^2 - 2(4w)(3) + (3)^2

16w^2  - 24w + 9

Please help. What are the measures of ∠a, ∠b, ∠c and ∠d? Explain how to find each of the angle measure.
MissTica

Angle a has a little square box in it, which means right angle, which is equal to 90 degrees.

Angle A = 90 degrees

Angle A m B and the 59 forms a straight line which needs to equal 180

Angle B = 180 - 59 - 90 = 31

Angle B = 31 degrees.

Angle C is a vertical angle with A and B, so Angle C = 90 + 31 = 121 degrees.

Angle D is a vertical angle with 59, so equals 59 degrees.
