HELP WITH 4. AND 5. Thanks in advance

Answer:

The radius is 3.66 if you need to round it would be 3.70.

Step-by-step explanation:

r= c/2[tex]\pi[/tex]

23/2pi= 3.66

The radius of the circle for the circumference of the circle is 23 inches is,

⇒ r = 3.66 inches

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We have to given that;

The circumference of the circle is 23 inches.

Now, We know that;

The circumference of the circle = 2πr

Where, r is radius of the circle.

Hence, We get;

⇒ 2πr = 23

⇒ πr = 23/2

⇒ 3.14 × r = 11.5

⇒ r = 11.5 / 3.14

⇒ r = 3.66 inches

Answer:

It will take 9.6 minutes to travel 24 cm.

Step-by-step explanation:

(;;;

Answer:

9.6 minutes.

Step-by-step explanation:

First we need to find how many minutes it takes the snail to travel 1 cm.

to do this we need to divide the time it takes by the distance traveled.

4 ÷ 10 = 0.4. So, the snail takes 0.4 minutes to travel 1 cm.

Next we need to find how long it takes to travel 24 cm.

to do do that we need to multiply how long it takes the snail to travel 1 cm by the number of cm it needs to travel.

0.4 x 24 = 9.6. So, it takes the snail 9.6 minutes to travel 24 cm.

Step-by-step explanation:

Answer:

slope, m = 5

Step-by-step explanation:

Recall that the slope-intercept form of a linear equation can be written:

y = mx + b  or f(x) = mx + b

where m is the slope of the line.

in our case, we are given

f(x) = 5x - 4

if we compare this with the general equations above, we can see that

slope = m = 5

hence the slope is 5

Answer:

2 hours or 120 minutes

Step-by-step explanation:

So, let's assume that she studies the same amount each day. If she has studied math for a total of 60 minutes, she should have studied for 4 days because 60 (total) divided by 15(time each day) would equal to 4 (period of time). So we have to multiply 30 minutes by 4 (period) to get 120 minutes, which is 2 hours.

Answer:

I think it would be B)

Step-by-step explanation:

This problem seems badly worded and/or vague.

It looks like you plugged x = 3 into the inverse [tex]f^{-1}(x)[/tex] function to get 3 as the output, which is correct.

However it seems like your teacher wants you to find the (x,y) point on f(x). This means s/he is asking "what x value will get us y = 10?" As you found through working with the inverse, the x value x = 3 does that.

We can see it as such

f(x) = 3x+1

f(3) = 3*3+1

f(3) = 10

So in a sense, you were working backwards.

The point (3,10) is on the graph of f(x)

While the point (10,3) is on the graph of [tex]f^{-1}(x)[/tex]

Answer:

D. 15 pounds

Step-by-step explanation:

35-20=15

The range of the data that represents the number of pounds of trash collected by each teenager is 15.

The range is the difference between the Maximum value of the data set and the Minimum value of the dataset. Therefore, we can write the range as,

Range = Maximum value of the data set - Minimum value of the dataset

Given the data for the number of pounds of trash collected by each teenager as 26, 26, 21, 22, 20, 25, and 35.

Now, from the data, the Maximum value of the data set is 35 and the Minimum value of the dataset is 20. Therefore, we can write the range of the data set as,

Range = Maximum value of the data set - Minimum value of the dataset

          = 35 - 20

          = 15

Hence, the range of the data that represents the number of pounds of trash collected by each teenager is 15.

Answer:

$860

Step-by-step explanation:

Jonae makes $16.50 an hour and worked 40 hours.  Multiply the hours worked by the amount of money she earned.

$16.50 × 40 = $660

The stored made $600 on a table and $400 on chairs, which, in total, is $1000.  Since Jonae gets paid 20% of all of the furniture sales, multiply the total sales by the percentage.

$1000 × 0.2 = $200

Add together the earnings she made per hour and the earnings she made from the furniture store's sales.

$660 + $200 = $860
