Answer:

60 minutes

Step-by-step explanation:

Given that Employee I can finish washing a car in 30 minutes. and

employee 2 can finish washing a car in 20 minutes.

Assuming that both will wath the car together after n minutes.

So, n must be the integral multiple of 30 as well as 20.

For niminum value of n,  n must be the lowest common factor of 30 and 20.

[tex]\Rightarrow n = LCM(30,20) \\\\\Rightarrow n = 60.[/tex]

Hence, after 60 minutes, they will wash a care togethre.

Answer: Diana donates $125 each month.

Step-by-step explanation:

Let x = Amount of money Diana donates each month.

Money she donates in a year = 12x  [ 1 year = 12 months]

Given: Money she donates in a year = $1500

So, [tex]12x=1500\Rightarrow\ x=\dfrac{1500}{12}=\$125[/tex]

i.e. Amount of money Diana donates each month = $125

Hence, Diana donates $125 each month.

Answer: 33.3%

Step-by-step explanation:

Cost price of the car = $13500

Value of car one year later = $9000

Decrease in value of car = $13500 - $9000 = $4500

The percent of decrease of the value of the car will then be:

= Decrease in value of car / Cost price × 100

= $4500 / $13500 × 100

= 1/3 × 100

= 33.3 %

Answer:

200 students must agree to attend in order for the school to have the festival.

Step-by-step explanation:

200 is 40% of 500. We can also use fractions to figure this out.

[tex]\frac{40}{100} =\frac{x}{500}[/tex]

For 100 to become 500 it must be multiplied by 5. And whatever we do to the denominator we have to do to the numerator. So we multiply 40 × 5 = x

x = 200

[tex]\frac{40*5}{100*5} = \frac{x}{500}[/tex]      

[tex]\frac{40}{100} =\frac{200}{500}[/tex]

Answer:

maybe 25 bc 37-12= 25

but also if u put it on top of the building then the bottom of the ladder on the bottom of the building aka ground it might be 25 ft

Answer:

35

Step-by-step explanation:

a^2 + b^2 = c^2

12^2 + b^2 = 37^2

144 + b^2 = 1369

1369 - 144 = 1225

sqrt of 1225 is 35

Answer:

(C)85.56 cm², 12.4 cm

Step-by-step explanation:

The Area of the screen of the new phone is :

19.68cm² + Area of the current phone screen size

The current phone screen size has dimensions: 6.1 cm and 10.8 cm,

Area of the current phone screen size = 6.1 cm × 10.8cm

Area of the current phone screen size = 65.88 cm²

Hence, The Area of the screen of the new phone is :

19.68cm² + Area of the current phone screen size

= 19.68cm² + 65.88cm²

= 85.56 cm²

The new phone screen must have an area of 85.56cm², which is the product of 6.9 cm and ___

The is calculated as:

85.56cm²/6.9cm

= 12.4cm

Therefore, the new phone screen must have an area of 85.56cm², which is the product of 6.9 cm and 12.4cm

Answer:

t=6

Step-by-step explanation:

Solve for tt by simplifying both sides of the equation, then isolating the variable.

Answer:

t=6

Step-by-step explanation:

We first use the addition property of equality by adding 8 to both sides. This cancels out the "-8" on the left-hand side of the equation.

We get: 1/3t= 2.

Then, we multiply 3 to both sides of the equation to cancel out the fraction on the left-hand side of the equation.

We get: t=6

This is your final answer.

Answer:

A

Step-by-step explanation:

if h(x)=(x/2)-6, find h(10)

What this means is that wherever there is an x on the right hand side, replace it with a 10

h(10) = (10/2) - 6

h(10) = 5 - 6

h(10) = -1

Answer:

C: S≤35h+42

Step-by-step explanation:

Since the competitor charges $35 per hour PLUS 42(individually), it is 35h+42.

Suzzette's charges should be NO MORE than the competitor, so it could include the SAME amount too. So S(suzzette) is lesser than Or equal to 35h+42.

The answer is C, S≤35h+42

Answer:

y = -3x + 2

Step-by-step explanation:

y = mx + b

m is the slope and b is the y-intercept

So the slope is -3 as it's going down, down is negative, by 3 units and only going to the right one unit while doing so. The y-intercept is where the line is intercepting on the y-axis. So it's: y = -3x + 2
