Answer:

56

Step-by-step explanation:

I assume each person in the group must have 1 pencil AND 1 eraser each.

Since you have more pencils than erasers, then the limiting factor is the number of erasers. So a group of 56 people will have 1 pencil And 1 eraser and Clare will have 24 pencils left over (assuming Clare has her own pencil and eraser - if not then the group size is 55 assuming Clare is not in the group)

sorry if it's too confusing

Answer:

C. 16

Step-by-step explanation:

A number squared means you need to multiply it by itself

So, 4 x 4 = 16

Answer:

c. 16

Step-by-step explanation:

multiply 4 two times because it's squared

4 x 4 = 16

Answer:

30.96° to the nearest hundredth

Step-by-step explanation:

Let x = angle of elevation

tan x = 60/100 = .6

x = arctan .6

x ≅ 30.96°

Answer:

65

Step-by-step explanation:

because 5 and 7 are the same angle that means the opposite of the 65 has to also be 65

Answer:

6 and 20

The answer is 9 because 4+5=9

Step-by-step explanation:

Answer:

Step-by-step explanation:

(3 - 8)/(1 + 4)= -5/5= -1

y - 8 = -(x + 4)

y - 8 = -x - 4

y = -x + 4

Answer:

She walks back for 4.2 hours

Step-by-step explanation:

Notice that we don't know the distance of the race (so let's name it "d").

She clearly would spend less time running (t1) the distance d at 7 mph, than when coming back walking (t2) at 3 mph.

But we know that the addition of both times must be 6 hours which is what she has to spend:

t1 + t2 = 6

Considering the equation that relates distance (D), time(t) , and speed (v) as:

v = D/t

we can solve for the times t1 and t2 in each trip (running vs walking){

t1 = d/7

t2 = d/3

then when we add these two equations term by term, we get:

t1 + t2 = d/7 + d/3

extract d common factor;

t1 + t2 = d (1/7 + 1/3)

replace t1 + t2 with the 6 hours:

6 = d (10/21)

multiply both sides by 21, and divide both sides by 10 to isolate d:

21 * 6 / 10 = d

d = 12.6 miles

Now knowing the distance she run and walked, we can find the time she spent walking back (t2)

t2 = 12.6 /3 = 4.2 hours

Answer:so multiply 12*2=24 and 24*5=120 Is your answer .

Answer:

1/16

Step-by-step explanation:

divide 5 into 80 to get 16 which 5 is 1/16th of 80

Step-by-step explanation:

Given

f(x) = 3x² + 9

g(x) = 5x

(fog)x = f ( 5x)

= 3 ( 5x) ² + 9

= 3 * 25x² + 9

= 75x² + 9

Answer:

Initial value

Step-by-step explanation:

Initial value never changes, whatsoever.

Slope is either a constant increase or decrease.

Unit rate, rate of change, and "per" all describe a rate at a certain point which is always fluctuating.
