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

Need help ASAP please!!! The formula determines the magnitude of an earthquake, where I is the intensity of the earthquake and S
snow_lady [41]

Answer:

100

Step-by-step explanation:

M = log(I/S)

The intensity of the first earthquake:

8 = log(I₁/S)

10⁸ = I₁/S

I₁ = 10⁸ S

The intensity of the second earthquake:

6 = log(I₂/S)

10⁶ = I₂/S

I₂ = 10⁶ S

The ratio is:

I₁/I₂ = (10⁸ S) / (10⁶ S)

I₁/I₂ = 100

It is 100 times stronger.

Nadia is a stockbroker. She earns 11% commission each week. Last week, she sold 7,200 worth of stocks. How much did she make las
elena55 [62]

Answer:

She made 792 dollars that week. I'm assuming it is just asking for the yearly commission she made. That would be 41,184 dollars a year.

Step-by-step explanation:

7200 x 0.11 = 792 Weekly

52 Weeks in a year

792 x 52 = 41184 Yearly (if that's what it's asking for)

5.75% of x = 28000<br> What is x?
kkurt [141]

Answer:

x = 486956.5217

Step-by-step explanation:

5.75% of x = 28000

Of means multiply

Change the percent to a decimal

.0575 * x = 28000

Divide by .0575 on each side

.0575/.0575 * x = 28000/.0575

x = 486956.5217

Mr. Alvarado needs 15 1/8 pounds of chicken feed to fill his feeder. He has one bag of chicken feed that weighs 3 1/2 pounds and
Crazy boy [7]

Answer:

B: 8 7/8 Lbs

Step-by-step explanation:

answer = 15\frac{1}{8} -3\frac{1}{2} -2\frac{3}{4}

step 1 find a common denominator

common denominator - 8

* apply *

\frac{1^*^1}{8^*^8} =\frac{1}{8} \\\\\frac{1^*^4}{2^*^4} =\frac{4}{8} \\\\\frac{3^*^2}{4^*^2} =\frac{6}{8}

now we have

15\frac{1}{8} -3\frac{4}{8} -2\frac{6}{8}

step 2 make each fraction a improper fraction

We can do this my multiplying the big number by the denominator and adding that to the numerator.

15*8=120\\120+1=121\\\frac{121}{8} \\\\3*8=24\\24+4=28\\\frac{28}{8} \\\\2*8=16\\16+6=22\\\frac{22}{8}

now we have

\frac{121}{8} -\frac{28}{8} -\frac{22}{8}

Now we can subtract

remember when subtracting fractions you only subtract the numerators. ( so we keep the denominator as 8 )

so 121 - 28 - 22 = 71

so the answer is \frac{71}{8}

finally we want to change the answer back into a mixed fraction

To do this we divided 71 and 8

8 can go into 71 8 times

8 * 8 = 64

71 - 64 = 7

We're left with 8\frac{7}{8}
