It take zoe 12.5 minutes to swim 20 laps around the pool.what is zoe's unit rate?

Answers

Answer: 37.5 seconds

Step-by-step explanation:

Turn into seconds so 12.5 x 60 (because there are 60 seconds in one minute) which gives you 750 seconds

Then divide by 20 to find the time taken for one lap so you get 37.5 seconds

The test scores for a group of students are shown. 87, 72, 98, 84, 72, 65, 72, 70, 58, 91, 81, 84
What is the mode of the scores?
A.
84
B.
78.8
C.
98
D.
85.5

Answers

Mode is the number that occurs most often. Out of those numbers, 72 would be the mode. But since that's not an option, I would say 84. 
the mode is 72 because 72 appears three times  and the others are shown twice but 72 isn't an answer and the only other one with the most often is 84 which appears twice so the answer would be A

The cafeteria made 96 ounces of pudding they put pudding into 7 ounce cups how many of the cups of pudding can the cafeteria fill completely

Answers

Given:
96 ounces of pudding
7 ounce cups

We simply divide 96 by 7 to get the number of cups the pudding can fill. We can do the long division.
  
     13 5/7
7 |96
    7↓                7 * 1
    26
    21                7 * 3
      5

The pudding can completely fill up 13 cups of 7 ounce cups.
You do 96 divided by 7 and that's 13 and 5/7. That's 13 ounces.

Step-by-step explanation:

the measure of one angle is eleven more than four times a number another angle is twice the first angles measure the sum of the measures of the angles are 195 degrees what is the measure of each angle

Answers

Answer=65° & 130°

195°=angle1+angle2
195°=(11+4x)+2(11+4x)
195°=33+12x
subtract 33 for both sides
162=12x
13.5=x

Now lets solve for the measure of the angles

angle1=11+4x
angle1=11+4(13.5)
angle1=11+54
angle1=65°


angle2=2(11+4x)
angle2=2(11+4(33.5))
angle2=2(11+54)
angle2=2(65)
angle2=130°
x, y, and z are the angles
so
x is 11 more than 4 times y
x=11+4y

z is twice the first angles measure
z=2x

the sum of the angles is 195
x+y+z=195

so we have
x=11+4y
z=2x
and
x+y+z=195
make everything y
subsitute 11+4y for x
11+4y+y+z=195
subsitute 2x for z
11+4y+y+2x=195
subsitute 11+4y for x
11+4y+y+2(11+4y)=195
distribute
11+4y+y+22+8y=195
group according to type
(4y+y+8y)+(11+22)=195
add like terms
13y+33=195
subtract 33 from both sides
13y=162
divide both sides by 13
y=12 and 8/13
subsitute
x=11+4y
x=11+4(12 and 6/13)
x=11+48 and 24/13
x=11+49 and 11/13
x=60 and 11/13
z=2x
z=2(60 and 11/13)
z=120 and 22/13
z=121 and 9/13

the angles are
12 and 6/13
60 and 11/13
121 and 9/13 or aprox

12.46
60.85
121.69

Expand and simplify (x+2)(x+1)

Answers

So first you would need to FOIL the problem (first-outer-inner-last) so you would multiply x by x and get {x²} then you would multiply x by 1 so you would get just plain {x} then multiply 2 by x so to get {2x} then multiply the last terms 2 and 1 together to get {2} so then put it all together = x² + x + 2x + 2 then you add like terms together so you end up with = x² + 3x + 2 as the answer
Here, we have to FOIL. 

(x+2)(x+1) = x^2+3x+2
