Answer: 8

Step-by-step explanation: i took the test

1.25 days would be taken for 3 men to complete the same job.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that 12 men 5 days to complete a job

We have to find for how many days three men can complete the same job.

Let x be the time taken by 3 men to complete the job.

Formulate a proportional equation.

12/5=3/x

Apply cross multiplication

12x=15

Divide both sides by 12

x=15/12

both 15 and 12 are multiples of 3

x=5/4

x=1.25

Hence, 1.25 days would be taken for 3 men to complete the same job.

Answer:

RS=6

ST=11

Step-by-step explanation:

answer is above

The value of x is 7 and the measure of the line segment RS is 6 units, ST = 11 units, and RT = 11 units

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Point S is between points R and T on RT.

RS = 2x - 8

ST = 3x - 10

RT = 17

From the above information:

RT = RS + ST

17 = 2x - 8 + 3x - 10

17 = 5x - 18

35 = 5x

x = 35/5

x = 7

RS = 2x - 8 = 2(7) - 8 = 6 units

ST = 3x - 10 = 3(7) - 10 = 11 units

RT = 17 units

Thus, the value of x is 7 and the measure of the line segment RS is 6 units, ST = 11 units, and RT = 11 units.

Answer: C. best fits the word problem.

Step-by-step explanation:

The reason C. best fits is because the bare minimum $20 she has to pay plus .10 times whatever amount of minute's she spends talking has to equal $100 for her to stay in budget. A good example would be say she spends 800 minutes in total on her phone. 0.10 times 800 is 80. So in this hypothetical situation, it would be 20 + 80 = 100.

Her walking rate in miles per hour is 2

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

Given;

Gianna walked 12 miles in 6 hours

6hours= 12 miles

1hour= 12/6miles

1hour= 2miles

Therefore, the rate of gianna by unitary will be 2mph

A more appropriate domain would be all real numbers except x = 5.5

Step-by-step explanation:

Given that the domain of a rational function consists of the set of real numbers but excluding those real numbers that results in a zero in the denominator

The given graph of the function has a vertical asymptote at s = 5.5 which indicates a value for which the function is not defined and at x = 5.5, and as such the value (5.5) of the asymptote is not a member of the function's domain

The values of the domain of a function consisting of a reciprocal must exclude does that result in a zero denominator.

The domain of the function that represents Jada's trip is the set of input value the function can take

The appropriate domain is: all real numbers except x = 5.5

From the graph, we can see that:

This means that the input of the graph cannot be 5.5

Hence, an appropriate domain would be: [tex]\mathbf{x \ne 5.5}[/tex]

Answer:

7.96 square inches.

Step-by-step explanation:

Area of a circle given a circumference is given by formula:

[tex]A = \frac{C^{2}}{4\pi}[/tex]

So substituting into equation we have: [tex]C= 10[/tex].

Therefore [tex]A = 10^{2}/4\pi = 100/4\pi=25/\pi =7.96[/tex] square inches.

The area of the circle is 7.96 square inches if the circumference of a circle is 10 inches.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

It is given that:

The circumference of a circle is 10 inches.

As we know the circumference of a circle is given by:

C = 2πr

C is the circumference of the circle.

r is the radius of the circle.

10 = 2πr

r = 5/π inches

As we know,

The area of the circle is given by:

A = πr²

Here, A represents the area of the circle.

Plug the value of the radius r in the above formula:

A = π(5/π)²

A = 25/π square inches

Take π = 3.14

A = 25/3.14

A = 7.96 sqaure inches

Thus, the area of the circle is 7.96 square inches if the circumference of a circle is 10 inches.

Ok so what you need to do is you need to get all the numbers and see which one is the right number so...

A. y = 11.2 that is wrong

B. y = 25 is wrong

C. y = 5 is right

D. y = 15 is wrong.

C is right because it would be 5 times 5 times 5. SO 5 times 5 is 25, and then u times it by 5 and you get 125!

C is correct

Hope this helps!!

Answer:

This is actually a cube root, since you need a cube root to cancel out the cube.

C, y = 5

Step-by-step explanation:

125 = 5 × 5 × 5 = 5^3

5 × 5 × 5 = 25 × 5 = 125.

Therefore the cube root of 125 = 5.

It REALLY helps when you break these into factors.

[tex] \sqrt[3]{125} = 5 , \: as \: {5}^{3} \: = 125 [/tex]

This is essentially asking what multiplied by itself three times is equal to 125.

Process of elimination can be used for any number cubed that is ≠ 125

i.e : 11.2^3 ≠ 125

11.2^3 = 11.2 × 11.2 × 11.2 = (11.2-1.2)(11.2+1.2)(11.2) = (11.2)((10)(12.4) + 1.2^2) = 124 + 1.44 = (125.44)(11.2) = 125.44(10+1+(2/10)) = 1254.4 + 125.44 + 25.088 = 1404.928 ≠ 125, y ≠ 11.2

I.e : 25^3 = 25 × 25 × 25 = 625 × 25 = (600+25)(25) = 625 + 6(25)(100) = 15000 + 625 = 15625 ≠ 125, y ≠ 25.

And i.e: 15^3 = 15 × 15 × 15 = 225 × 15 = (225)(10+5) = 225(10) + 225(10/2) = 2250 + 2250/2 = 2250 + 1125 = 3375 ≠ 125, y ≠ 15.

Answer:

y = 12

x = 10/3

Step-by-step explanation:

y = -3.6x + 12

From this equation, which is in slope intercept form (y = mx+b), we already know that b represents the y-intercept, so that means the y-intercept is 12.

To find the x-intercept, we need to make y equal 0 to find x. So:

0 = -3.6x + 12

-3.6x = -12

x = 3.33333 --> 3 1/3
