The given table of values represents a linear equation. What is the slope?

A. 4

B. 5

C. 3

D. 6​

Answers

Answer:

C. 3

Step-by-step explanation:

Formula for slope is given as [tex] m = {y_2 - y_1}{x_2 - x_1} [/tex]

The coordinates of any two points can be used in this formula. Let's use, (1, 5) and (2, 8).

Let,

[tex] (1, 5) = (x_1, y_1) [/tex]

[tex] (2, 8) = (x_2, y_2) [/tex]

Plug the values into the formula:

[tex] m = {8 - 5}{2 - 1} [/tex]

[tex] m = {3}{1} [/tex]

[tex] m = 3 [/tex]

Six friends arrive at a party their arrival increases the number of people at the party by 20% in total how many people are now at the party

Answers

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Suppose that the number of the people in the party is :

[tex]x[/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

20 % of x equals :

[tex] \frac{20}{100} \times x = 0.2x \\ [/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Thus ;

[tex]0.2x = 6[/tex]

[tex] \frac{2}{10}x = 6 \\ [/tex]

Multiply sides by 10

[tex]10 \times \frac{2}{10} x = 10 \times 6 \\ [/tex]

[tex]2x = 60[/tex]

Divided sides by 2

[tex] \frac{2}{2} x = \frac{60}{2} \\ [/tex]

[tex]x = 30[/tex]

There were 30 people in the party.

Thus there are ;

[tex]30 + 6 = 36[/tex]

People at the party now.

Mr. Carter is building a circular fire pit in his backyard. The diameter of the fire pit is 6 feet and he will fill the interior with gravel covering 5/6 of the area. How much gravel will he need?
A. 23.55 sq. ft.
B. 28.26 sq. ft.
C. 94.2 sq. ft.
D. 113.04 sq. ft.

Answers

Answer:

23.55

Step-by-step explanation:

To calculate the area I did the following equation

area = 3.14 (r) (r)

area = 3.14 (3) (3)

area = 28.26

The area is 28.26 but the question is asking how much gravel would be needed to fill 5/6 of the area.

The equation for 5/6 out of 28.26 is

28.26 (5/6) = 23.55

So the final answer is (a.) 23.55 sq. ft.

Write the income equation for a small business that
begins with $150 and grows by 20% each year. When
will the company's income be $300?

Answers

Answer:

in 4 years

Step-by-step explanation:

because you should find the 20% of 150

150×20=3000

3000÷100= 30

so 20% of 150 is 30

then you keep adding 30 to the results till you reach 300

The equation is 150+30x=300 and it takes 3 years for the company to earn $300.

Given that, a small business begins with $150 and grows by 20% each year.

We need to find when will the company's income by $300.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Now, 20% of 150=30

Let x be the number of years.

So, f(x)=150+30x

⇒150+30x=300

⇒30x=150

x=3

The equation is 150+30x=300 and it takes 3 years for the company to earn $300.

A.
5(12+t)=132
B.
5t+12=132
C.
5(12)+t=132
D.
5+12+t=132

Answers

Answer:

B

Step-by-step explanation:

5t + 12 = 132

We know the price of parking and we know what they paid in total. There are 5 members with the unknown price.

Answer:

B

Step-by-step explanation:

You're trying to find how much a ticket, which is t. you need 5 tickets for the family, plus the twelve dollar fee which is there anyways for the car, and it add up to 132. subtract 12 from 132 and you get 120. 120 divided by 5 is 24. so 24 dollars for a ticket, but the equation you would need is 5t+12=132

Find the sum of integers from 33 to 47:

Answers

Answer:

Step-by-step explanation:There are formulas to work this out, but you can also suss out an answer by a liberal application of critical thinking.

Okay, you want to add 51 + 52 + 53 + … + 99 + 100, right? (The … represents all the numbers in between, in case you were wondering.)

Well, that’s a total of 50 numbers. And if you know anything about addition, you know that it doesn’t matter what order you add them.

So you could also say 51 + 100 + 52 + 99 + 53 + 98 + … and so on.

Let’s see what happens. 51 + 100 = 151. So far so good.

Then, 52 + 99 also equals 151. And 53 + 98 also equals 151. Since there are 50 numbers, that’s 25 pairs that are going to add up to 151.

151 + 151 + 151 + 151 + … (21 more instances of 151).

So we can simplify our workload a bit. Instead of adding up all the numbers by hand, we can just multiply 151 by 25.

151 x 25 = 3775

From that, we can work out a generic formula that will allow you to add any sequence of numbers…without actually adding.

Let a be the first number in the sequence, and let n be the last number in the sequence. The number of numbers is (n - a) + 1. (You have to add 1, because if you just subtract, it’s like you’re losing the lowest number in the sequence).

So…you get the sum by adding the first and last number in the sequence, and then multiplying that result by half of the total number of numbers.

(a+n)((n−a)+12)  

an−a2+a+n2−an+n2  

−a2+a+n2+n2  

−a(a−1)+n(n+1)2  

Let’s check to see if it works!

−51(51–1)+100(100+1)2  

−51(50)+100(101)2  

−2550+10,1002  

75502  

3775  

Note that if the starting number were 1, the formula would simplify to  n(n+1)2

Sum of integers=?

Solution:

Given numbers:

[tex]\to \bold{33,34,35,36,37,38,39,40,41,42,43,44,45,46,47}[/tex]

Using formula:

[tex]\bold{S = \frac{n(a + l)}{2}}[/tex]

[tex]n=15\\\\a=33\\\\l=47 \\\\ \bold{S = \frac{15(33 + 47)}{2}}\\\\[/tex]

    [tex]\bold{= \frac{15(80)}{2}}\\\\\bold{= \frac{1200}{2}}\\\\\bold{= 600}[/tex]

Therefore, the sum of the integers "600".

The length of a rectangle is eight centimeters less than twice its width. If the perimeter of
the rectangle is 20 centimeters, find its dimensions.

Answers

Answer:

width of given rectangle = 6 cm

length of given rectangle =  4 cm

Step-by-step explanation:

Let the breadth be x cm

given that

The length of a rectangle is eight centimeters less than twice its width

length of rectangle in terms of x =  2(breadth ) - 8 =  2x - 8

we know perimeter of rectangle is given = 2(l + b)

thus, perimeter of given rectangle is = 2 ( x +  2x - 8) = 6x - 16

also given perimeter of the rectangle is 20 centimeters

thus,

6x - 16 = 20

6x = 20 + 16 = 36

x = 36/6 = 6

Thus,

width of given rectangle = 6 cm

length of given rectangle = 2*6 - 8 = 4 cm
