Have you done any work on these problems yet?  It's unrealistic (and not helpful to you in the long run) to expect someone else to do them for you and to give you the answers.  Still, I will address Problem #16:

Convert    40 yards
                -------------
                   4 sec

to the equivalent speed in miles per hour.  You'll need two of the following three identities:  3 feet = 1 yard; 5280 feet=1 mile; 3600 sec = 1 hour.

Why not reduce this fraction first?  (40 yards) over (4 sec) reduces to 10 yards/sec.

Now convert yards to miles, using 5280 feet = 1 mile and 3 feet = 1 yard.  I see you already have reduced that 40/4 to 10.  Your result should be

10 yards/sec.

Know what to do next?   See my previous paragraph.  Please share your work.

If AD and BD are bisectors of CAB and CBA respectively. Find the sum of angles x and y.
olchik [2.2K]
The picture in the attached figure

step 1
we know that
It is given that AD and BD are bisectors of ∠CAB and ∠CBA respectively.
Therefore,
x = ∠CAB/2 -----> equation 1
y = ∠CBA/2 -----> equation 2

step 2
In triangle ABC,
∠CAB + ∠CBA + ∠ACB = 180° ----> [The sum of all three angles of a triangle is 180°]
∠CAB + ∠CBA + 110° = 180°
∠CAB + ∠CBA = 180° - 110°
∠CAB + ∠CBA = 70° ------> divide by 2 both sides
∠CAB/2 + ∠CBA/2 = 70/2 -------> equation 3
substitute equation 1 and equation 2 in equation 3
x+y=35

hence

the answer is
x+y =35°
⇒ x + y = 35° ...[From equation (1) and (2)]

Unit rate<br>How many cents would you earn per minute? <br>Show work<br>ASAP
Yanka [14]
So, it depends. Imma give you two answers, all of which are the same at the end. They just have different ways to do it.

1. So, it's<span> $9 per hour, or $9 per 60 min </span>
<span>You can write a ratio: 9/60 = n/1 </span>
<span>In this case you have to divide 9 by 60 cause
60/60 = 1 </span>
<span>And n=0.15 </span>
<span>Answer: you earn 15 cents per min. 

2.</span><span>$9 = 900 cents </span>
<span>900 cents divided by 60 minutes = 15 cents in a minute.

Hope this helps love!! :)</span>
