Hi Help please?!!!!!

Answer:

423.12

Step-by-step explanation:

V = π r^2 h

V = 3.14 x 3.5^2 x 11

V = 3.14 x 12.25 x 11

V = 38.465 x 11

V = 423.115

423.115 Simplifyied is 423.12

Answer:

b 28 and 62

Step-by-step explanation:

X is equal to 14 so other angle is 2x which is.2multiplied to X which gives 28degrees

X is equal to 14 and the other.angle is 3xplus 20 so 3x is 42 plus 20 gives 62

pls give me brainliest I need it to upgrade my rank

Answer:

b 28 and 62

Step-by-step explanation:

Answer:

C= 41.45

Step-by-step explanation:

The circumference is given by C = 2[tex]\pi[/tex]r, since the diameter is 13.2 then the radius is half of that so r = 6.6

So C = 2(3.14) (6.6) =41.448

Answer:

11/15

Step-by-step explanation:

There are 15 dots and 11 of them are either blue or red, so the answer would be 11/15

Answer:

150 sq ft

Step-by-step explanation:

length = 10

width = 10 × 1.5 = 15

10 x 15 = 150

It was a debate between the northerners and southerners (forgive my spelling). The northerners feared the addition of more slave states and a corresponding lack of reprenestation of their intrests in the North. For the southern slave holders, new western lands would be a boon (helpful) to enslaved people and the Louisiana purchase threatened to entrench and expand their suffering to western territories.

Answer:

15x+25 ; 70

Step-by-step explanation:

Given that,

Fernando cleans pools for the summer for $25 an hour plus a supply fee of $15.

Here, $25 is constant and $15 increases as the number of hour increase. For x hours, the cost for Fernando to clean a pool is given by :

y = 15x+25

For 3 hours,

y = 15(3)+25

= 45 + 25

= 70

So, the required option is (c) " 15x+25 ; 70 ".

Answer:

1/4

Step-by-step explanation:

1/2 x 1/2

Step-by-step explanation:

The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.

Answer:

The answer is x= -6

Step-by-step explanation:

3(x-8)=10x+18

3x-24=10x+18

3x-24=10x+18

Both side +24

3x=18+24+10x

Both side -10 x

3x-10x=42

-7x= 42

Both side divided by 7

x= -6

Answer:

F(5)= 22

F(9)= 34

Step-by-step explanation:

F(x)=3x+7

F(5)= 3(5)+7

F(5)= 15+7

F(5)= 22

F(9)= 3(9)+7

F(9)= 27+7

F(9)= 34

Answer

The answer is p=25

Answer:

p = 25

Step-by-step explanation:

Isolate the variable, p. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents

Multiplication

Division

Addition

Subtraction

~

First, divide 10 from both sides of the equation:

(10(p - 7))/10 = (180)/10

p - 7 = 180/10

p - 7 = 18

Next, add 7 to both sides of the equation:

p - 7 (+7) = 18 (+7)

p = 18 + 7

p = 25

25 is your answer for p.

Answer:

30

Step-by-step explanation:

Given:

The function is

[tex]f(x)=x[/tex]

To find:

The tangent line to the graph of f(x)=x at point (0,0).

Solution:

We have,

[tex]f(x)=x[/tex]

It is a linear function because the highest power of the variable is 1.

We know that the tangent line to a linear function at any point is the line itself.

Derivative of given function is

[tex]f'(x)=1[/tex]

So, slope of the tangent line is 1. It is given table the tangent line passes through the point (0,0). The equation of tangent line is

[tex]y-0=1(x-0)[/tex]

[tex]y=x[/tex]

Therefore, the tangent line to the graph of f(x)=x at point (0,0) is y=x.

Answer:8

Step-by-step explanation:

Truck:car

6:2 or simplified to 3:1, which means 3 trucks for every 1 car.

24 trucks divided by 3 gives you 8.

Answer:

8 cars

Step-by-step explanation:

Set up a proportion to model this situation. First, write and simplify the given proportion.

trucks to cars;

6 : 2

Simplify,

3 : 1

Assuming that the rate at which trucks and cars are present in the parking lot is constant, one can make the expression,

trucks : cars

3 : 1 = 24 : x

Where (x) represents the unknown amount of cars. One can use cross products to solve this proportion,

3 : 1 = 24 : x

24 = 3x

Inverse operations,

24 = 3x

8 = x
