Lin ran 2 3/4 miles in 2/5 of an hour, Noah ran 8 2/3 miles in 4/3 of an hour. How long would it take Lin and Noah to run 1 mile at that rate?

Answer:

Subtraction

Step-by-step explanation:

This is because you would minus 3 from both sides, leaving:

2x=8

Then, you would divide both sides by 2 to isolate x.

x=4

Answer:

3: add the numbers and if they add up to 180 its a triangle

4 add the 2 numbers then subtract it by 180 to get your 3rd number

Step-by-step explanation:

Option B is the correct answer, x+15=41

Answer:

to find the rate of fencing, you should find the perimeter of the rectangle.

2(l+b)

2(155+125)

2*180

360m

cost of fencing = 360*10

= Rs 3600

now to find the cost of fielding, find the area

(l*b)

155*125

19375 square mtr

cost of fielding = 19375*15

= Rs 290625

Problem 7

--------------------------------------

Work Shown:

p(x) = x^4+x^3-kx-x+6

If (x-2) is a factor of p(x), then x = 2 is a root of p(x). This is a special case of the remainder theorem.

This means p(2) = 0

Replace every x with 2 and solve for k

p(x) = x^4+x^3-kx^2-x+6

p(2) = 2^4+2^3-k(2)^2-2+6

p(2) = 16+8-4k-2+6

p(2) = 28-4k

0 = 28-4k .... replace p(2) with 0

4k = 28

k = 28/4

k = 7

The polynomial

p(x) = x^4+x^3-7x^2-x+6

has the factor (x-2)

============================================

Problem 8

--------------------------------------

Work Shown:

Check out the diagram below to see the synthetic division table. We're after the remainder which is highlighted in yellow.

An alternative is to use direct substitution

p(x) = 2x^4+4x^3-x^2-5

p(-3) = 2(-3)^4+4(-3)^3-(-3)^2-5 ... replace every x with -3

p(-3) = 2(81)+4(-27)-9-5

p(-3) = 162-108-9-5

p(-3) = 40  

This helps confirm we got the right remainder and the right answer.

Answer:

12 + 40d ≥ 100

Answer:

y[tex]\geq 2.2[/tex]

Step-by-step explanation:

John wants to complete at least 100 miles. he has completed 12 which means he only has 88 left. If you divide 88(miles left) by 40(time left) you get 2.2 miles. so he would need a minimum of 2.2 miles a day to bike 100 miles.

Let's simplify step-by-step.

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

From the question the equation is

y = - 2x - 1

Comparing with the general equation above

Slope = - 2

Y - intercept = - 1

Answer:

you need 32.5 cups of red for the same shade of purple

Step-by-step explanation:

2:5

13:32.5

Answer:

32.5 cups of red

Step-by-step explanation:

Lets take it step-by-step.

So to make purple paint you mix 2 parts of blue and 5 parts of red. So if you use 13 cups of blue you need to use 32.5 cups of red because...

13 divided by 2 = 6 1/2, so you would have to multiply 5 x 6 1/2 which is 32.5

Next time you come across a problem like this take the large number you have Ex. 13, and divide it by the smaller number you know Ex. 2, and then multiply the number that you've gotten by dividing Ex. 6 1/2, with the other small number Ex. 5, and then you have your answer.

Answer:

-6

Step-by-step explanation:

When you divide fractions, you multiply the inverse.

So, -3/2 divided by 1/4 is -3/2 x 4/1 = -12/2

                                        Simplified = -6

Answer: D

Step-by-step explanation:

Ten thousandths is the fourth place

The expression one hundred seventy-five ten-thousandths in the standard form will be 175,000. The correct option is A.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.  

Given that the number is one hundred seventy-five ten-thousandths. The standard form of the number can be written as below,

Standard form = one hundred seventy-five ten-thousandths

Standard form = 175,000

Hence, the standard form is 175,000.

Step-by-step explanation:

Answer:

x = 13

y = 20

Step-by-step explanation:

The question lacks the required diagram. Find the diagram attached.

In line geometry, the oppositely directed angles are equal. According to the diagram shown;

4x = 6x - 26 (oppositely directed angles)

We can get the value of x from the equation as shown;

4x = 6x - 26

Subtract 6x from both sides

4x-6x = 6x-6x-26

-2x = -26

x = -26/-2

x = 13

Similarly:

6y+8 = 7y-12 (oppositely directed angles)

collect like terms

6y-7y = -12-8

-y = -20

multiply both sides by -1

-(-y) = -(-20)

y = 20

Hence x = 13 and y = 20

Answer:

The monthly cash inflow is $273.6

Step-by-step explanation:

It is given that hourly wage is $18 and his net pay is 72% of his earnings.

First, calculate the 72% of $18.

72% of his earnings is [tex]\$18\times \frac{ 72}{100}= \$12.96[/tex].

Tyrone works 40 hours per week .

The number of working hours in a month is: [tex]40\times4=160 \text{ hours}[/tex]

For 1 hour is he was getting $12.96.

For 160 hours he will get: [tex]160\times 12.96=\$2073.6[/tex]

His total monthly cash inflow is $2073.6 - $1,800=$273.6

Hence, the monthly cash inflow is $273.6

Answer:

x = -3970, g = 2015

Step-by-step explanation:

Solve this system of linear equations by substitution:  substitute 2g + 60 for x in the first equation.

Then we have:

3g - 2(2g + 60) = -2135

Performing the indicated multiplication, we get:

3g - 4g - 120 = -2135, or

     -g             =    -2015

Then g = 2015.  Then x = 2(-2015) + 60, or x = -3970

The solution is x = -3970, g = 2015

Answer:

The third option, or (x, y) ---> (x + 4, y - 3)

Step-by-step explanation:

When moving right on the horizontal axis, you always add so since we are moving 4 units to the right, that would be x + 4, and when moving down on the vertical axis, we always subtract, so since we are moving 3 units down, that would be y - 3
