Question

talia has 2 red,1 blue and 4 green balls of the same size in the bag talia pulls one ball out of the bag without looking what is the probability that talia will pull a red ball out of the bag 2/2,5/7,2/5,2/7??

Solution 1

2/7

There are 2 red ones and 7 in total, and to find probability, you put possible outcomes / total, so 2/7

Question

Chole and ingrid are packing boxes with books They have 238 books Each box will fit 8 books Chole says 29 boxes is enough to pack all the books ingrid thinks they need 30 boxes Explain who is correct show work

Solution 1

If you do 238 devided by 8 its 29.75 so they need 30 boxes.

Solution 2

238/8 = 29.75

Ingrid is correct because if you use 29 boxes, you'll have a remainder so 30 boxes is the best option so nothing will be left behind. Round 29.75 and you'll get 30.

Question

talia has 2 red,1 blue and 4 green balls of the same size in the bag talia pulls one ball out of the bag without looking what is the probability that talia will pull a red ball out of the bag

Solution 1

There are 2 reds and the total amount of balls is 7

So the probability would be 2/7

(possible outcomes)/(total)

So the probability would be 2/7

(possible outcomes)/(total)

Solution 2

the answer is 2/7 there 2 red balls left and 7 balls all together so I am just saying the answer is 2/7 I just took the unit test

please give me the brainless thank you

Question

The cost of a taxi is $2.75 plus $0.40 per half mile.write an equation to find the cost of a taxi ride that is m miles long How much would it cost you to travel 45 miles m=#miles c=#cost 1.C stand for ____.
a.cost
b.circle
2.what is the equation?
a.c=-0.4m+2.75
b.c=0.4m+2.75
3.what is the solution?
a.$6.35
b.$6.25

Solution 1

1) It tells you in the question c = cost, so cost would be the answer

2) 2.75 is the fixed rate so we would keep it as is. C is the cost which would the total, so c = ?m + 2.75

0.40 per half mile so you put 0.40m because it varies depending on the amount of miles

That makes the equation c = 0.40m + 2.75

3) Now to find how much it costs for 45 miles, you plug 45 for m

c = 0.4 * 45 + 2.75

c = 20.75

Not sure why it isn't an option

Question

A number j minus 14 is less than −21.

Solution 1

If you are supposed to write the inequality, it would be

j - 14 < -21

j represents the number j

minus 14 is taking away or subtracting 14

together, they are less than -21, which is why < is used

j - 14 < -21

j represents the number j

minus 14 is taking away or subtracting 14

together, they are less than -21, which is why < is used

Solution 2

A number j minus 14 is less than −21

j - 14 < -21

if you need to find j then

j - 14 < -21

+14 +14

j < -7

hope it helps

j - 14 < -21

if you need to find j then

j - 14 < -21

+14 +14

j < -7

hope it helps

A. [1.6+(-6.5)]
B. [-1.6-(-6.5)]
C. [-6.5-(-1.6)]
D. [-6.5-1.6]

Solution 1

The asnwer correct is c

Solution 2

**Answer:**

I am 96 percent it is c

Hope this helped!!!!

Question

Aaron bought a large basket of 59 apples for $22.95. He also bought a small basket of 18 apples for 8.95. Which amount is the closest estimate of the cost per apple?

Solution 1

22.95+8.95 = 31.90

31.90/77 = .41

So, it'd be .40 if you were rounding.

31.90/77 = .41

So, it'd be .40 if you were rounding.

Question

Julie counted 25 players on a visiting soccer team. The actual number of players on the visiting soccer team was 27. What is the percent error in Julie’s measurement? If necessary, round to the nearest percent.

Solution 1

I did 2/27 which equals 0.074

So its basically 74

So to make it a percentage we need to move it 2 spaces=

7.4%

So its basically 74

So to make it a percentage we need to move it 2 spaces=

7.4%
