Answer:

The wrestler gains 10.8 kilograms every 2 months.

Step-by-step explanation:

The rate of change of the equation is 5.4 kilograms per month. To find the weight gain, we can multiply the rate of change by 2, the number of months. :)

Answer:

80kg

Step-by-step explanation:

A young sumo wrestler decided to go on a special diet to gain weight rapidly. W(t) models the wrestler's weight (in kilograms) as a function of time t (in months). W(t)=80+5.4t

What was the wrestler's weight before his special diet?

Again the function is  W(t)=80+5.4t,

We know that W is the weight while t stands for time in months

so we can start by using t at 0,3,4

when t=0

W(0)=80+5.4*0=80kg

W(3)=80+5.4*3=96.2kg

W(4)=80+5.4*3=101.6kg

so before his special diet he was 80kg

U(8, 9) and V(2, 5) are the endpoints of a line segment. What is the midpoint M of that line segment?
Pavel [41]

Answer:

The midpoint M is (5,7)

Step-by-step explanation:

m = ( \frac{x1 + x2}{2} , \frac{y1  + y2}{2} )

U(8,9)

V(2,5)

m = [(8+2)/2 , (9+5)/2]

= [(10/2) , (14/2)]

= (5,7)

Determine the radius, to the nearest inch, of a large can of tuna fish that has a volume of 66 cubic
Mnenie [13.5K]

The radius of can is 2.524 inches

<em><u>Solution:</u></em>

Given that large can of tuna fish that has a volume of 66 cubic  inches and a height of 3.3 inches

To find: Radius

Given a large can of tuna fish, we know that can is generally of cylinder shape, we can use the volume of cylinder formula,

<em><u>The volume of cylinder is given as:</u></em>

\text{ volume of cylinder}= \pi r^{2} h$

Where,

"r" is the radius of cylinder

"h" is the height of cylinder

\pi is a constant equal to 3.14

Substituting the given values in above formula,

66 = 3.14 \times r^2 \times 3.3\\\\66 = r^2 \times 10.362\\\\r^2 = \frac{66}{10.362}\\\\r^2 = 6.369\\\\r = 2.524

Thus the radius of can is 2.524 inches

the price per share of a stock decreased from $90 per share to $36 per share. by what percent did the price of the stock decreas
givi [52]

Answer:

60%

Step-by-step explanation:

we know that

the price per share of a stock decreased from $90 per share to $36 per share

In this problem

$90 represent the 100%

so

using proportion

Find out what percentage represent the difference of ($90-$36)

($90-$36)=$54

Let

x ----> the percentage of the difference

\frac{100\%}{\$90}=\frac{x}{\$54}\\\\x=54(100)/90\\\\x=60\%

Using the provided table, calculate the effective tax rate for a single taxpayer with a taxable income of $52,000.
barxatty [35]

Answer:

Option C is correct ,14.2%

Step-by-step explanation:

In order to determine the effective tax rate of a taxpayer with taxable income of $52,000,the starting point to determine how much in taxes the taxpayer pays as shown below:

First tax bracket=$9,525*10%=$952.5

Second tax bracket=$952.50+(12%*($38700-$9,525))

                                =$952.50+$3501

Third tax bracket(where the taxpayer belongs)=4453.5 +(22%*($52,000-$38,700))

third tax bracket tax=4453.5+$2926 =$7379.5

Since the total tax payable of  $7379.5   is now computed,

effective tax rate=tax paid/taxable income=7379.5/52000 =14.2%
