1. The table below shows Vanessa's height in inches for two different years.

YEAR (x) 2000&2005
HEIGHT (y) 48 inches 54 inches

Which is a correct conclusion about the rate of change shown in the table?

A. Vanessa grows about 41.7 inches per year. B. Vanessa grows about 6 inches per year.
C. Vanessa grows about 1.2 inches per year.
D. Vanessa grows about 83 inches per year.​

Answers

Answer:

Option C, Vanessa grows 1.2 inch per year

Step-by-step explanation:

Based on the given information it is clear that from 2005 to 2000 i.e in 5 years height of Vanessa has increased by 6 inch i.e from 48 inch to 54 inch.

If we estimate the per year growth, we can deduces that Vanessa grows by[tex]\frac{6}{5} = 1.2[/tex] inch.

Hence, option C is correct

Vanessa grows 1.2 inch per year

A peanut butter cookie recipe calls for 3 1/2 cups of flour to make 6 dozen cookies. How many cups of flour must be used to make 20

Answers

Complete Question

A peanut butter cookie recipe calls for 3 1/2 cups of flour to make 6 dozen cookies. How many cups of flour must be used to make 20 dozen?

Answer:

11 2/3 cups of flour

Step-by-step explanation:

From the above question:

6 dozen = 3 1/2 cups of flour

20 dozen = x

Cross Multiply

6 dozen × x = 20 dozen × 3 1/2 cups of flour

x = 20 dozen × 3 1/2 cups of flour/6 dozen

x = 20 × 7/2 /6

x = 140/2 ÷ 6

x = 140/2 × 1/6

x = 140/12 cups of flour

x = 11 8/12

= 11 2/3 cups of flour

Therefore, 11 2/3 cups of flour must be used to make 20 dozen.

In a class, there are 24 boys to 18 girls. What is the ratio of boys to the total number of students in the class?

Options:

b. 24:42
c. 42:24
d. 18:42

Answers

Answer:

B. 24:42

Step-by-step explanation:

24 boys to 18 girls, total students:

24 + 18 = 42

Ratio of boys to the total number of students:

28 : 42

Correct choice is B

Answer:

Solution given;

girl's=18

boys=24

total no of students=24+18=42

now

the ratio of boys to the total number of students in the class=[tex] \frac{24}{42} [/tex]

=24:42is the required ratio.

Samuel ate
1/2 of the oatmeal cookies and 2/3 of the
sugar cookies for a total of 18 cookies. The number
of oatmeal cookies he ate was six more than the
number of sugar cookies he ate. How many sugar
cookies did he eat?

Answers

Answer:

9 sugar cookies

Step-by-step explanation:

Let the number of sugar cookies be x.

If the number of oatmeal cookies was six more than the number of sugar cookies, then oatmeal cookies can be represented by x + 6.

So, we know that Samuel ate half of the oatmeal cookies and 2/3 of the sugar cookies, for a total of 18 cookies. Let's represent this with an equation.

x + x + 6 = 18

2x + 6 = 18

2x = 12

x = 6

So x represents 6. Recall that he ate 2/3 of the sugar cookies, so 2 parts of sugar cookies is 6.

Therefore, we can do this:

(3/2) x 6 = 9 cookies

This is essentially saying, "I want to find 3 parts if 2 parts is 6 cookies."

He ate 9 sugar cookies.

_2. You have a part-time job 4 days per week, 5 hours per day. How many hours will you work in two weeks?
A) 10
B) 20
C) 40
D) 80

Answers

Answer:

C) 40

Step-by-step explanation:

For every one day your work is 5 hours.

1 day = 5 hours

Set up a proportion so it would be:

[tex]\frac{1 day}{5 hours} = \frac{4 days}{x hours}[/tex]

4 days x 5 hours = 20 hours/week

So now you know you know you work 20 hours/week, then multiply by 2 since they're asking how many hours will you work in two weeks:

20 hours x 2 weeks = 40 hours in two weeks

Kevin rode 24 km in 2 hours. At that rate, how long would it take him to ride 120 km?

Answers

Answer:

10 hours

Step-by-step explanation:

We can convert the speed to km/h, and to do this, you simply have to find the amount Kevin rides in 1 hour. So,

24/2 = x/1

x = 12

So, now we see that Kevin rides at approximately 12 kmph. Now, instead of finding the distance, we need to find the hour at 120 km.

12/1 = 120/x

x = 10

What is a function?

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

y = 5x - 1

For x = -1,

y = -5 - 1 = -6

For x = 0,

y = - 1

For x = 1,

y = 5 - 1 = 4

For x = 2,

y = 10 - 1 = 9

Thus,

The table values are given above.

noah wrote that 6+6=12 then has write 6+6-n=12 what property of equality justifies that the equation are equivalent​

Answers

Answer:

This may be written incorrectly.

Assuming that this is written correctly, then we have that:

6 + 6 = 12

is equivalent to:

6 + 6 - n = 12

Here the properties that we can add 0 in one side of the equality and this does not change the equality, so this only works if n = 0.

If we instead had:

6 + 6 = 12

is equivalent to:

6 + 6  - n = 12 - n

In this case, Noah used the additive or subtractive property of equality.

this property says that in an equality we can add (or subtract) the same value on both sides, and it does not change the equality.
