what is the slope when the points are (5, -20) and (-10, 40)

Answer:

The problem uses the perimeter formula.  P = 2w + 2l   where w is the width, and l is the length.

We know the length (l) is 3 inches longer than it's width (or l = w+3).  Substitute w +3 into Perimeter equation.

P = 2w + 2(w+3).  That simplifies to P = 4w + 6.

Since P + 42,   we have 42 = 4w +6.  With some simple algebra we find that w = 9 and l = 12.

Answer:

The length of h is 3cm.

Step-by-step explanation:

You are looking for h. In order to find h you need the equation of area of a triangle, which is a=1/2bh. They give you base and they give you area. Plugging the numbers in, the equation is 7 7/8 cm^2= 1/2(5 1/4)(h). Now you solve by getting h by itself.

2(7 7/8 cm^2)= (1/2(5 1/4)(h))2

(15 3/4)/(5 1/4)= ((5 1/4)(h))/(5 1/4)

3=h

Answer:

The answer is h+ 3cm

x = 0

Step-by-step explanation:

Given

- 4 =  3 + 7(x - 1) ← distribute and simplify right side

- 4 = 3 + 7x - 7

- 4 = 7x - 4 ( add 4 to both sides )

0 = 7x  , then

x = 0

Answer: The barrel holds about 58.44 gallons of oil .

Step-by-step explanation:

Given : For cylinder , diameter = 22 inches and height = 35.5 inches

radius = 11 inches [half of diameter]

Volume of cylinder  [tex]=\pi r^2h[/tex], where r= radius and h = height.

Volume of cylinder  [tex]=\dfrac{22}{7}\times(11)^2\times 35.5=13500.14\text{ cubic inches}[/tex]

Since, There are 231 cubic inches in a liquid gallon, so.

1 cubic inch = [tex]\dfrac{1}{231}[/tex] gallon.

13500.14 cubic inch = [tex]13500.14\times\dfrac{1}{231}\approx58.44\text{ gallons}[/tex]

Hence, The barrel holds about 58.44 gallons of oil .

Given:

The number of pages she has left to read is 276−35d, where d represents the number of days she has been reading.

To find:

The explanation of each part of the expression.

Solution:

The given expression is

[tex]276-35d[/tex]

Here, 276 is initial number of pages or total number of pages.

d is number of days she has been reading.

-35 represents the remaining pages decreased by 35 per day.

35d is number of pages she reads in d days she has been reading.

Therefore, total number of pages is 276 and number of pages she reads each day is 35.

Answer:

36 tickets

Step-by-step explanation:

First you set up your equation, which would be 12 + 0.50x = 30. Next you subtract 12 on both sides to get 0.50x = 18. Divide both sides by 0.50 to get x = 36.

Answer:

36CDs

Step-by-step explanation:

The number of CDs in Walter's collection can be represented by x. The number of CDs in Brian's collection is 3 times the number in Walter's collection.

Hence, Brian's collection = 3x

The total number of CDs in both collections is 144.

We have the Equation:

x + 3x = 144

4x = 144

x = 144/4

x = 36

Therefore, the number of CDs in Walter's collection is 36 CDs

Answer:

2640

Step-by-step explanation:

Yes:No = 7:5

Total votes = 6336

So, 7x+5x = 6336

12x = 6336

x = 6336/12 = 1056/2 = 528

Number of No votes = 5*528 = 2640

Answer:26

Step-by-step explanation:

The value of f(3) is 26.

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given function:

f(x) = 5(x + 1) + 2x

as, we have to find the Sean running in week 3

So, f(3) = 5(3 + 1) +2 (3)

f(3) = 5(4) + 6

f(3) = 20 +6

f(3) =26

Hence, the value of f(3) is 26.

Answer:

The circle's area is 153.93804 feet^2

Step-by-step explanation:

The formula for the area of a circle is [tex]a = \pi r^{2}[/tex]

Using this formula, input the number 7 in for "r" and solve:

a = pi ( 7 )^2

a = pi ( 49 )

a = 153.93804 feet^2

The area of the circle is 153.93804 feet^2. Round the number to the specified decimal point.

Correct question:

Adrian needs to be at school at 7:45 am. It takes him 15 minutes to walk to school, 5/12 hour to eat breakfast, 0.7 hour to get dressed, and 0.15 hour to shower. What time should he wake up.

Answer:

Adrian should wake up by 6.14 am

Step-by-step explanation:

Given;

time to walk to school, = 15 mins

time to eat breakfast = 5/12 hour = 25 mins

time to get dressed = 0.7hour = 42 mins

time to shower = 0.15 hour = 9 mins

time Adrian needs to be in school = 7.45 am

Count from this time he needs to be at school backwards by subtracting the time he will spend before reaching school;

7.45 am - 15 mins = 7.30 am

7.30 am - 25 mins = 7.05 am

7.05 am - 42 mins = 6.23 am

6.23 am - 9 mins = 6.14 am

Therefore, Adrian should wake up by 6.14 am
