Surface Area of Cylinder=2πrh+2πr2
Where r is the radius of the cylinder and h is the height of the cylinder. Find the surface area when r is 3 inches and h is 5 inches.

A. 112π in²
B. 48π in²
C. 80π in²
D. 50π in²

Answers

Answer 1

Answer: B. 48 pi in^2

Step-by-step explanation:

Plug the given values into the equation.

So the SA = 2*pi*3*5 + 2*pi*3^2

SA = 30pi + 18pi

SA = 48 pi in^2

The function g(x) is graphed. Which statements about the function are true? Choose three options. O g(1) = -1 O g(0) = 0 O 94) = -2 -5 O g(1) = 1 O g- 1) = 1 in​

Answers

Answer:

g(0) = 0

g(1) = 1  

g(-1) = 1  

Step-by-step explanation:

g(1) = -1 means that when 1 is inputted into the function, the output is -1.

Therefore, y = -1 when x = 1.  From inspection of the graph, when x = 1, y = 1, therefore this is untrue.

g(0) = 0 ⇒ y = 0 when x = 0. From inspection of the graph, when x = 0, y = 0. Therefore this is true.

g(4) = -2  ⇒ y = -2 when x = 4. From inspection of the graph, we cannot read when x = 4, but y > 0 when x = 4.  Therefore this is untrue.

g(1) = 1  ⇒ y = 1 when x = 1. From inspection of the graph, when x = 1, y = 1. Therefore this is true.

g(-1) = 1  ⇒ y = 1 when x = -1. From inspection of the graph, when x = -1, y = 1. Therefore this is true.

Question 9
In △QRS , ∠R is a right angle and the measure of ∠S is 22° .

(image below)

Which equation can be used to calculate the measure of ∠Q ?

A
x+22=180

B
x+22=90

C
22−x=180

D
22−x=90

Answers

Answer:

i think the answer is b

because,

if x+22=90

x=90-22=68

we know that the sum of the three angles of a triangle is 180

so, that means

90+22+68 should be 180

and it is 180, so the answer must be b

I need help find the value of x?

Answers

Add the two angles and then subtract from 180* to find the missing angle

So,

145* + 15* = 160*

180* - 160* = 20*

Answer: x = 20*

which statement best explain best explains whether the table represents a linear or non linear function (100 POINTS) HURRYYYY PLSSS

Answers

Answer:

It is a linear function because there is a constant rate of change in both the input and output values

Step-by-step explanation:

To determine if the function is linear, calculate the differences between the y values.

If the differences are constant, or the same value, the equation is linear and has a constant slope. If the differences are not the same, the equation is not linear.

difference between y values (output)

7 - 4 = 3

3 - 1 = 3

1 - -2 = 3

⇒ the function is linear

difference between x values (input)

-2 - -5 = 3

-5 - -8 = 3

-8 - -11 = 3

⇒ the function is linear as there is a constant rate of change in both the input and output values

Given,GRAM is a parallelogramRG = 19RP = 12AR = 15Solution:

i) Since,

Diagonals of a parallelogram bisect each other so,

RM = 2 × RP

=> RM = 2 × 12

=> RM = 24 (Ans)(i)

ii) Since,

Opposite sides of a parallelogram are equal so,

GM = AR = 15

=> GM = 15 (Ans)(ii)

iii) Since,

Opposite sides of a parallelogram are equal so,

AM = RG = 19

=> AM = 19 (Ans)(iii)

Given :

GRAM is a parallelogram where

RG = 19RP = 12AR = 15

Solution :

We know that,

Opposite sides of a parallelogram are equal in length.Diagonals of a parallelogram bisect each other.

So,

RG = 19

⇢ RG = AM [Opposite sides]

AM = 19 .

Since,

⠀⠀RP = 12

⇢ RM = 2(RP) [Diagonals bisect each other]

⇢ RM = 2(12)

RM = 24

Since,

⠀⠀AR = 19

⇢ AR = GM [Opposite sides]

GM = 15 .

A 21 foot ladder is placed against a vertical wall of a building, with the bottom of the ladder standing on level ground if 14 foot from the base of the building. How high up the wall does the ladder reach

Answers

Answer:

15.65 foot

Step-by-step explanation:

Pythagoras theorem can be used

a² + b² = c²

a being 14
b being unknown ( x )
c being 21

hence,

14² + x² = 21²
196 + x² = 441

x = √245

A number from 0 to 9 is randomly selected and then a letter from A to D is randomly selected. What is the probability that the number 3 and a consonant are selected?

Answers

Answer:

[tex]\frac{1}{10}*\frac{3}{4} =\frac{3}{40}[/tex]

Step-by-step explanation:

There are 10 numbers 0,1,…9

Probability that 3 is selected is  [tex]\frac{1}{10}[/tex]

Again, there are 4 letters A,B,C & D of which 3 are consonants and 1 is vowel. So, probability of selecting a consonant is [tex]\frac{3}{4}[/tex] . Hence, the required probability is [tex]\frac{1}{10} *\frac{3}{4} = \frac{3}{40}[/tex]

2) Chloe scored (-5) though she has got 7 correct answers . how many questions has she attempted not correctly ? ​

Answers

[tex]\huge\sf {solution}[/tex]

#1

Marks awarded for onecorrect answers = 3 Marks awarded for 12 correct answers = 3 × 12 = 36 Marks obtained for incorrect answers = 20 - 36 = -16 Marks given for 1 incorrect answer = -2

Therefore, ( - 16 ) ÷ ( - 2 ) = 8

hence , irene has attempted 8 questions incorrectly

#2

Marks scored by chloe for 7 correct answers = 3 × 7 = 21 chloe scored = -5 Marks obtained for incorrect answers = -5 - 21 = -26 Marks awarded for 1 incorrect answer = -2

Therefore , number of incorrect answer = -26 / -2 = 13

We need to find 20% of 45.26

20% = 20/100 = 1/5 = 0.2

Of is related to multiplication

So, 20% OF 45.25 is 0.2 times 45.26

0.2 * 45.26 = 9.052

9.052 needs to be rounded to 9.05

The answer is $9.05
