You need to decide whether to hire three landscapers or hire just two but buy a faster mower; both options will deliver the same revenue. If landscapers cost you $18 an hour and work 2000 hours a year, and the new mower will cost $8,000, which option will be cheaper for you over the next three years?

Answer:

8

Step-by-step explanation:

8/2 equals 4 minus 10 is -6

Answer:

-6= n/2 -10

-12=n-20

-12-n=-20

-n=-20+ 12

-n=-8

n=8

Step-by-step explanation:

1. multiply both sides of the equations by 2

2.Move the N varaiableto the left hand side and change its sign

3. Calculate the sum of -20+12

4. change the signs from negative N to positive N giving you the value of 8

n=8

Solved.

Answer:  The shadow of the tree is 280 feet long.

Step-by-step explanation:

We can use a ratio to solve this:

Use the Height to shadow for each. This works because the fractions must reduce to the same equivalent.

5/10 = 140/x

We can see that 5/10 is 1/2, so we need another fraction using 140 as the numerator that is equal to 1/2.  That's easy here: Multiply 140 × 2 to get the new denominator, 280 that replaces x. That is the length of the shadow.

If you have a less obvious ratio, you can use Cross Multiplication to solve the unknown value in the ratio:

5/10 = 140/x  Cross multiply the numerator of the left side times the denominator on the right side, and the denominator on the left side by the numerator on the right side:

5 × x = 10 × 140

5x = 1400  Divide both sides by 5 (the 5s "cancel" on the left)

5x/5 = 1400/5

x = 280

I hope this helps, especially when you see more questions like this in the future.

Answer:

Step-by-step explanation:

we have 18,000 people

growth 2% per year

time=11 years

18,000*2/100=360 growth per year

360*11=3,960.00

18,000+3,960=14,960

Answer:

We need to consider the division 8/2.

We know that 1/2 is equal to 0.5, then we just could write a problem where we need to multiply 8 by 0.5, this can be something like:

"You found a box with 8 kittens in it, they are a lot of kittens for you to care, so you decide to give the 50% of them to your friend. How many kittens you end up having?"

Well, there are 8 kittens, which represent the 100%.

how many kittens are the 50%?

We have the equations:

8 kittens = 100%

x = 50%

Take the quotient of these two equations:

x/8 kittens = (50%/100%)

x = (50%/100%)*8 kittens

x = 0.5*8 kittens

and 0.5 = 1/2

then:

x = 0.5*8 kittens = (1/2)*8 kittens

x = 8/2 kittens = 4 kittens.

Complete Question

The coach recorded how fast his runners ran 1 mile. Emmett ran a mile in 9.73 minutes, Kate ran a mile in 10.87 minutes, and Rubin ran a mile in 8.46 minutes. How many more minutes did Emmett run than Robin?

a. 1.37 minutes

b. 1.27 minutes

c. 2.27 minutes

d. 1.27 seconds

Answer:

1.27 minutes

Step-by-step explanation:

Emmett ran a mile in 9.73 minutes

Kate ran a mile in 10.87 minutes

Rubin ran a mile in 8.46 minutes.

How many more minutes did Emmett run than Robin?

This is calculated as:

Number of minutes Emmett ran - Number of minutes Rubin ran

= 9.73 minute - 8.46 minutes

= 1.27 minutes

Option b is correct

Answer:

224,999,992.5

Step-by-step explanation:

i used the BEDMAS rule.

first of all i added 5+10 which is in the bracket.

then, i multiplied 5×2 because in bedmas rule .. tho division comes first in BEDMAS. we check what is comes first from multiplication and division.

after that . i multiplied 9999999×6 then, as you know. if a digit is before the bracket is multiplied to the digit inside the bracket. i mutiplied the product of 9999999×6 with 15.

i dunno what you meant by (5+10)%4. so i just assumed that you meant (5+10)÷4. after i got the product of 59,999,994 ×15. i divided it with 4. now as we are done with BEDM. now only addition and subtraction is left. there is no subtraction.. so i added the products and the quotient .

Now... add 5+10+224,999,977.5

you get the ans 224,999,992.5

Do correct me if i am wrong.

Answer:

The value of x is 5 and the value of y is -2

Step-by-step explanation:

If the question is to determine the values of x and y, this can be related to the elimination method for solving simultaneous equations.

From the third linear equation, -13x = -65, the value of x can be determined.

-13x = -65

Divide both sides by -13

Then,

-13x/-13 = -65/-13

x = 5

∴ The value of x is 5.

To determine the value of y, the value of x is substituted into any of the first two equations. Say -10x + 5y = -60

-10x + 5y = -60

Substitute x = 5 into the equation

-10(5) + 5y = -60

-50 + 5y = -60

Add 50 to both sides

-50 +50 + 5y = -60 +50

Then,

5y = -10

Divide both sides by 5

5y/5 = -10/5

y = -2

∴ x = 5, y =-2

Hence, the value of x is 5 and the value of y is -2.

Answer:

25/32 kg

Step-by-step explanation:

The kinetic energy K of a body in motion measured in joules is given as

K = 1/2 mV^2

Where n is the mass in kg and V is the speed in m/s

Hence given that K is 25J and speed V is 8 m/s,

25 =1/2 * m * 8^2

25 = m *32

Divide both sides by 32

m = 25/32 kg

Step-by-step explanation:

Answer:

Please check the explanation.

Step-by-step explanation:

Given

C=24x+80

R=44x

To determine

What is the break-even point?

Given that

C represents the cost in dollars

R represents the revenue in dollars.

At the break-even point Cost (C) equals Revenue (R), so

R = C

44x = 24x+80

44x-24x = 80

20x = 80

divide both sides by 20

20x/20 = 80/20

x = 4

Thus, at x = 4 the value of Cost (C) equals Revenue (R).

i.e.

C = 24x+80 = 24(4)+80 = $176

R = 44x = 44(4) = $176

Answer:

(4, 176)

The price of the two items - the known price which is the blouse

Answer:

Option A

Step-by-step explanation:

Domain is the set of x values or input values of a function.

Range is the set of y values or output values of a function.

Given relation is,

2x + y = 4

Set if input values of domain → {-5, 0, 6}

Table for the input - output values,

x       -5        0        6  

y       14        4       -8  

Therefore, range of the given relation will be the set of output values.

{14, 4, -8}

Option A is the answer.

Answer:

You would move each point on y=P(x) up by three. Or add 3 to each y coordinate

Step-by-step explanation:

This is because we're not manipulating the value of x before it gets multiplied by P.

For example:

If x is set to equal 5 and P equal to 2, then the parent function would have a coordinate of (5,10) since 2(5)=10 but the new function would have a coordinate of (5,13) since 2(5)+3= 13 due to order of operations (2×5 =10, then we add 3).

Answer:

Step-by-step explanation:

Step 1:

Plot y=P(x) from x=-a to x=a with x=0 as the middle point of the distance between a and -a.

Step 2:

Add the value of +3 to each point of y=P(x), ie, y=P(x)+3 meaning that the graph y=P(x) will be pulled up three units on the y axis.
