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)

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

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%

Question

What is the approximate circumference of a circle with a radius of 42.1 km? A. 5565.4 km
B. 1391.3 km
C. 264.4 km
D. 132.2 km

Solution 1

C.264.4 that should answer your question

Solution 2

Circumference of circle = 2*pi*r

= 2*22/7*42.1

= 264.4 km

Therefore, the circumference of the circle is**264.4 km**

= 2*22/7*42.1

= 264.4 km

Therefore, the circumference of the circle is

Question

Write a story problem about 40 apples and 17 pears

Solution 1

There were 40 apples with 17 pears that died.

Question

Claire’s mother is 4 years more than twice Claire’s age. The sum of their ages is 58 years.

Solution 1

Claire's age = x

claire's mothers age = 2x+4 ( 4 more than twice claire's age)

sum is addition

x + 2x+4 = 58

add like terms ( x +2x = 3x)

3x +4 = 58

subtract 4 from each side:

3x = 54

divide both sides by 3

x = 54 /3

x = 18

Claire is 18 years old

Claire's mother is 2*18 = 36 +4 = 40 years old

claire's mothers age = 2x+4 ( 4 more than twice claire's age)

sum is addition

x + 2x+4 = 58

add like terms ( x +2x = 3x)

3x +4 = 58

subtract 4 from each side:

3x = 54

divide both sides by 3

x = 54 /3

x = 18

Claire is 18 years old

Claire's mother is 2*18 = 36 +4 = 40 years old

Solution 2

Let x = Claire's age

Claire’s mother is 4 years more than twice Claire’s age = 2x + 4

The sum of their ages is 58 years:

x + 2x + 4 = 58

3x + 4 = 58

3x = 54

x = 18

Claire's age = 18

Claire’s mother = 2(18)+4 = 36 + 4 = 40

Claire’s mother is 4 years more than twice Claire’s age = 2x + 4

The sum of their ages is 58 years:

x + 2x + 4 = 58

3x + 4 = 58

3x = 54

x = 18

Claire's age = 18

Claire’s mother = 2(18)+4 = 36 + 4 = 40
