Answer:

Jim ran 60 miles

Step-by-step explanation:

T (Toby) - 5 miles

K (Katie) - 4T , 4(5), 20

J (Jim) - 3K, 3(20), 60

Answer:

Jim ran 60 miles.

Step-by-step explanation:

First off I would take note of the information given.

Toby = t

Kate = k

Jim = j___________________________________________

j = 3k

t = 5

4t = k  

Since we already know Tim ran 5 miles we multiply 5 x4 to get 20. So Kate ran 20 miles.

3 times Kate's amount is Jim's. So 20 x 3 = 60.

Hope that helps and have a great day!

Answer:

1. Anjali answered 10 questions incorrectly

2. Rohan answered 16 questions incorrectly

Step-by-step explanation:

1 .The mark given for one correct answer = 5

That means that the mark given for 10 correct answers = 5 × 10 = 50

But Anjali's score = 30

Also, the marks gotten for incorrect answers = 30 - 50 = -20

Mark given for one incorrect answer = -2.

Therefore, number of incorrect answers would be;

= (-20) ÷ (-2)

= 10

•Anjali answered 10 questions incorrectly.

2. Total marks = -12

Number of correct answers = 4

Total marks for correct answers = 4 × 5 = 20

Also, marks for incorrect answers = -2 × Number of incorrect answers

Therefore,

Total marks = Marks for the correct answers + Marks for the incorrect answer

-12 = 20 + (-2) × Number of incorrect answers

-12 - 20 = -2 × Number of incorrect answers

-32 / 2 = Number of incorrect answers

Number of incorrect answers = 16

• Rohan answered 16 questions incorrectly.

Answer:

3 months

14 of each type of staff

Step-by-step explanation:

Starting employees

Junior residents = 11

Senior readings = 5

Additional personnel at a rate of 1 junior resident per month and 3 senior residents per month

Junior residents = 11 + m

Senior readings = 5 + 3m

Where,

m = number of months

How long will that take?

Equate both expression

11 + m = 5 + 3m

11 - 5 = 3m - m

6 = 2m

Divide both sides by 2

m = 6/2

= 3

m = 3 months

Junior residents = 11 + m

= 11 + 3

= 14

Senior readings = 5 + 3m

= 5 + 3(3)

= 5 + 9

= 14

Answer:

5 and 0

Step-by-step explanation:

The answer to x > -45, are all number that are larger than -45.

5: Is 50 larger than -45

-100: Is 55 smaller than -45

-50: Is 5 smaller than -45

0: Is 45 larger than 45

5 and 0 are correct because they are both larger than -45.

Answer:

Well from the question I can only confirm that X (-45, infinity) is the possible answer. The answer would be A and D because 5 is greater than -45, while 0 is also greater than -45.

Answer:8

Step-by-step explanation:

Step 1:

Let us first find the decrease in amount.

Decrease in amount = 150 -120 = $30

Step 2:

Now let us find the ratio of decrease in price to original price.

So the ratio is 1/5 or in decimal its 0.2.

Step 3:

To find percentage decrease we change this decimal number 0.2 two places to the right side, so it becomes 20 %

 The price decreased by 20%

Answer:

The number of rods used by the company is 43 rods/hour

Step-by-step explanation:

Given;

diameter of the cylinder, d = 6 cm

radius of cylinder, r = d/2 = 3 cm

height of the cylinder, h = 40 cm

Volume of the steel rod is given by;

V = πr²h

V =  π(3)²(40)

V = 1131.12 cm³

The number of rods used by the company on average each hour is given by;

[tex]n = \frac{48,607 \ cm^3}{hour} *\frac{1}{1131.12 \ cm^3}\\\\ n = 43 \ rods/hour[/tex]

Therefore, the number of rods used by the company is 43 rods/hour

Answer:

Step-by-step explanation:

Given the monthly salary of project managers modeled by the function

f(x)= x^4 -10x^2+10,000

To know the number of years that a project manager be eligible for a $20,000 monthly salary, we will substitute f(x) = 20,000 and solve for x as shown:

20,000 = x^4 -10x^2+10,000

x^4 -10x^2 = 20000-10000

x^4 -10x^2 = 10,000

x^4 -10x^2 - 10,000 = 0

(x^2)^2-10x^2 - 10000 = 0

let P = x^2

P^2 - 10P -10000 = 0

P = 10±√10²-4(-10000)/2

P = 10 ±√100+(40000)/2

P = 10 ±√40100/2

P = 10 ±200.2/2

P = 210.2/2

P = 105.1

Since P = x^2

105.1 = x^2

x = √105.1

x = 10.25

Hence it will take like after 10 years for the manager to earn a $20,000 monthly salary

Step-by-step explanation:

Answer:

The width of the box is 15 inches and its height is 12 inches

Step-by-step explanation:

Equations

The volume of a box of width W, height H, and length L is given by:

V=W*L*H

We know

L=10 inches

W=H+3

V=1800 cubic meters

Substituting:

1800=(H+3)*10*H

Operating and swapping sides:

[tex]10H^2+30H=1800[/tex]

Dividing by 10:

[tex]H^2+3H=180[/tex]

Rearranging:

[tex]H^2+3H-180=0[/tex]

Factoring:

(H-12)(H+15)=0

The only positive and valid result is:

H=12 inches

Thus,

W=H+3=12+3=15 inches

The width of the box is 15 inches and its height is 12 inches
