Answer:

240 minutes

Step-by-step explanation:

Half of 80 is 40. So multiply 40 by 4 which is 160 minutes then add the 80 which equals 240 minutes

Overall 240 minutes Lin spend doing homework from monday to friday.

What is an expression?

Expression in mathematical is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Since Lin spent 80 minutes on monday doing homework and from tuesday to friday he is doing half the work before which means he will be doing in 40 mintues now for 4 days that is from tuesday to friday.

Now overall time in mintues he spend on homework will be sum of mintues spent on monday and mintues spent from tuesday to friday :

overall = 80 + 40x4

           = 240 minutes

Therefore, overall 240 minutes Lin spend doing homework from monday to friday.

Answer:

base = 10 cm

Step-by-step explanation:

The height from the vertex is a perpendicular bisector of the isosceles Δ

This line divides the triangle into 2 right triangles with hypotenuse 13

Thus each right triangle is a 5- 12- 13 with legs 5 and 12

The height is 12 cm and the base 5 cm

Then the base of the isosceles Δ = 2 × 5 cm = 10 cm

Note Area = 0.5 × 10 × 12 = 60 cm²

Answer:

4,592.4

Step-by-step explanation:

925.14×15 = 13,877.1

615.65x30=18,469.5

18,469.5

- 13,877.1

= 4,592.4

Answer:

$55,108.80

Step-by-step explanation:

15 year mortgage

925.14/month times 180 months =

$166,525.20

30 year mortgage

615.65/month times 360 months =

$221,634

$221,634 - $166,525.20 =

$55,108.80

So the difference between the 15 year mortgage and the 30 year mortgage is $55,108.80

Answer:

125

Step-by-step explanation:

5^3 = 5 × 5 × 5 = 125

Given :

When price is $2 dollars he sells 2400 units .

When price is $8 dollars he sells 600 units .

To Find :

If x represents the price of trucks and y the number of items sold, write an equation for the demand curve.

Solution :

Two points are given :

[tex](x_1,y_1)=(2,2400)[/tex]

[tex](x_2,y_2)=(8,600)[/tex]

Now , slope is given by :

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\\\m=\dfrac{2400-600}{2-8}\\\\m=\dfrac{-1800}{6}\\\\m=-300[/tex]

Now , the equation of line containing these two points and slope -300 is :

[tex](y-y_1)=m(x-x_1)\\\\y-600=-300(x-8)\\\\y=-300x+2400+600\\\\y=-300x+3000[/tex]

Therefore , equation for the demand curve is [tex]y = -300x +3000[/tex] .

Hence , this is the required solution .

Answer:

KM = 4

Step-by-step explanation:

[tex] LM = 3x + 3 [/tex]

[tex] KM = 5x + 4 [/tex]

[tex] KL = 5x + 1 [/tex]

[tex] KL + LM = KM [/tex] (segment addition postulate)

[tex] (5x + 1) + (3x + 3) = 5x + 4 [/tex] (substitution)

Solve for x

[tex] 5x + 1 + 3x + 3 = 5x + 4 [/tex]

Combine like terms

[tex] 8x + 4 = 5x + 4 [/tex]

[tex] 8x + 4 - 4 = 5x + 4 - 4 [/tex]

[tex] 8x = 5x + 0 [/tex]

[tex] 8x - 5x = 0 [/tex]

[tex] 3x = 0 [/tex]

[tex] x = 0 [/tex]

[tex] KM = 5x + 4 [/tex]

Plug in the value of x

[tex] KM = 5(0) + 4 [/tex]

[tex] KM = 0 + 4 = 4 [/tex]

Answer:

41 days

Step-by-step explanation:

The membership would be worthwile if you swim an amount of days paying the daily entrance fee that would make your total cost equal to the cost of the membership. From that you can write the following expression:

3x=82+(1*x), x is the number of days you go to swim

Now, you can solve for x:

3x=82+x

3x-x=82

2x=82

x=82/2

x=41

According to this, the answer is that you would have to swim 41 days to make the membership worthwile.

Answer:

35.82 %

Step-by-step explanation:

Total no of electrician job = 67

No. of indentured apprentices = 24

____________________________________

Percentage mean per hundred,

Example for x percentage of any thing

literally it means if there are total no. of 100 things, then x  is the number of thing  in consideration.

Formula for  percentage calculation = (number of a particular thing/ total no of things out of which  the particular thing is considered) *100

______________________________________

Here,

Total no of electrician job = 67

No. of indentured apprentices = 24

percentage of  indentured apprentices = (Total no of electrician job /No. of indentured apprentices)   * 100 = 24/67 *100 = 35.82 %

Thus, there  35.82 % indentured apprentices  out of total electricians.

It means that if there were 100 electricians, then there would have been 35.82  indentured apprentices out of those 100 electricians.

Step-by-step explanation:

Drone motor that has a power of 25W. 1- What will be the working voltage of said motor if it has a consumption of 1.5A? 2- What will be the resistance of said motor?

Power of drone motor is 25 W

Current flowing through the motor is 1.5 A

Power of an electrical appliance is given by :

P = VI

V = working voltage of the motor

[tex]V=\dfrac{P}{I}\\\\V=\dfrac{25}{1.5}\\\\V=16.67\ V[/tex]

Voltage of the motor is 16.67 volts

Let R is the resistance of the motor. Using Ohm's law to find it as follows :

V=IR

[tex]R=\dfrac{V}{I}\\\\R=\dfrac{16.67}{1.5}\\\\R=11.113\ \Omega[/tex]

Hence, this is the required solution.

To begin this problem we call "the sum of the number" x. Now we have the equation 2(x)+5=20. This is the answer because it said to translate the equation. I think 2x+5+20 would be the correct translation.

Answer:

The correct answers are the following:

A) P=12n-275

B) 124

C) Decrease by $100

Step-by-step explanation:

A) P=12n-275 - Each person (n) pays $12, then the cost/expense ($275) is subtracted from the income to get the profit.

B) 1,213=12n-275  - Plug in the value for P ($1,213).

1,488=12n  - Add $275 to both sides.

124=n  - Divide both sides by $12.

n=124 - This the number (n) of people that attended.

C) P=12n-375 - Change the value for expense to $375.

P=12(124)-375  - Plug in the value for n (124).

P=1488-375  - Simplify and find the difference.

P=1,113 - This is your profit.

1,113-1,213=-100 - $100 reduction/decrease of profit (or -$100 to profit)

6%

Answer:

6%

Step-by-step explanation:

6×100÷100

Answer:

Simplifying

12r + -6s = t

Solving

12r + -6s = t

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '6s' to each side of the equation.

12r + -6s + 6s = 6s + t

Combine like terms: -6s + 6s = 0

12r + 0 = 6s + t

12r = 6s + t

Divide each side by '12'.

r = 0.5s + 0.08333333333t

Simplifying

r = 0.5s + 0.08333333333t

Step-by-step explanation:

sorry if this doesnt help

Answer:

r=s/2+t/12

Step-by-step explanation:

To find the answer, add 6s to both sides to get 12r=6s+t. Divide both sides by 12 to get the answer.
