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
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.
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?
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]

16. In Chapter 5, you discovered that when you construct the three midsegments in a triangle, they divide the triangle into four congruent triangles. Are the four triangles similar to the original? Explain why or why not
Answer:
A midsegment is the line segment connecting the midpoints of two sides of a triangle. Since a triangle has three sides, each triangle has three midsegments. A triangle midsegment is parallel to the third side of the triangle and is half of the length of the third side.

You’ve analyzed each game. Which game earns you more points?
A: game 1 ( 200 points per hit)
B: game 2 (points double on each hit)
C: It depends
Explain your answer.
Answer:
Game 2
Step-by-step explanation:
Each hit the points would double (point(x2))
Example:
1x2=2, 2x2=4, 4x2=8, 8x2= 16, 16x2=32, and so on.
Answer:
It Depends
Step-by-step explanation:
Sample Answer: For up to 11 hits, Game 1 gives the player higher scores. But for 12 or more hits, Game 2 does. That's because exponential growth eventually exceeds linear growth.
2. Explain how to calculate 8% of 350 by first calculating 1% of 350. Answer:
Answer:
$28Step-by-step explanation:
Find 1% of $350:
$350*1/100 = $3.5Find 8% of $350:
$3.5*8 = $28Here are the steps
First find 1% of 350Then multiply with 8/1=8 times with 1%Lets do
[tex]\\ \tt\longmapsto 0.01(350)=3.50[/tex]
Multiply with 8

In a class test , 3 marks are awarded for every correct answer and (-2) marks are awarded for every incorrect answer and no marks for not attempting any questions. ( find the following given below ).
1) Irine scored 20 marks . if she has got 12 correct answers , how many questions has she attempted incorrectly ?
2) Chloe scored (-5) though she has got 7 correct answers . how many questions has she attempted not correctly ?
[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 ) = 8hence , 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 = 13hence , chloe has attempted 13 questions not correctly

You have a coupon for 20% off your total. Your total comes to $45.26. How much will you get off your total?
Answer:
$9.05
Step-by-step explanation:
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
Hope this helps :)

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
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
help please it would be nice! and show work
Step-by-step explanation:
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 = 15Solution :
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 steel company sells 144 tons of steel every 3 years.
At this rate, what is the unit rate for the amount of steel sold every year. You can make a ratio table to help you think through this problem.
Answer:
48 tons of steel per year
Step-by-step explanation:
you can make it a ratio problem but you can also divide it
144 tons : 3 years
? : 1 year
take 144/3 and you get
48 tons
so
48 tons : 1 year
Answer:
Unit rate= 36
Step-by-step explanation:
Divide 144 by 4 and you get 36. So, the steel company made 36 tons of steel in 1 year and made 144 tons of steel in 4 years

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

Trying to get my grade up
Answer: x=4 and y=1
Step-by-step explanation:
From the first equation, we get y = 9 - 2x. Substitute this into the second equation we get
3x - 4(9 - 2x) = 8
3x - 36 + 8x = 8
11x = 44
x = 4
y = 9 - 2(4)
y = 1
Hope this helps

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
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
= 15.65 foot (answer)
