Answer:
vertices are rotation by 270° about the origin
R¹( 3, 2), S¹( 2, -1) and T¹ (-1,- 2)
Step-by-step explanation:
Explanation:-
The rule for a rotation by 270° about the origin is
( x,y) → (y,-x)
Given vertices are R(–2, 3), S(1, 2), and T(2, –1)
Given vertices are rotation by 270° about the origin
R¹( 3,-(-2)) , S¹( 2 , -1) and T¹ (-1 , -(2))
R¹( 3, 2), S¹( 2,-1) and T¹ (-1,- 2)

Answer: 11.375°
Step-by-step explanation:
55 + (4x + 17) + (4x + 17) = 180° Set up equation
4x + 4x + 55 + 17 + 17 = 180° Commutative Property of Addition
8x + 89 = 180° Combine like terms
8x = 91° Subtract 89 from both sides
x = 11.375° Divide both sides by 8

??
Answer:
22/15 or 1 7/15
Step-by-step explanation:
If you have two negatives in a row they make a positive, so the question is 4/5 + 2/3= ?. You can either plug that into a calculator and get 1.4666... or change the denominator to 15 and get 12/15 + 10/15.
please help me do question 10 :)
Answer:
A: sin(55.13+22.62) = .969
B: Cos(55.13-22.62) = .861
C: sin(2*55.13) = .96
D: cos(2*55.13) = -.28
E: tan(55.13+22.62) = 3.9375
F: cot=1/tan= 1/tan(55.13-22.62)= 1.6969
Step-by-step explanation:
I would like to preface this by saying that my trig is probably rusty so maybe double check my work. I will try to overexplain it so you can easily spot any errors I may make
To solve for x we know that sin(x)=4/5
we can solve for x by using the arc sin
This means that x=arcsin(4/5) which gives me around x=53.13
We can then use the same process for y but with 5/13
so arcsin(5/13) gives us around y=22.62
Then it's just a matter of plugging everything in
A: sin(55.13+22.62) = .969
B: Cos(55.13-22.62) = .861
C: sin(2*55.13) = .96
D: cos(2*55.13) = -.28
E: tan(55.13+22.62) = 3.9375
F: cot=1/tan= 1/tan(55.13-22.62)= 1.6969
Amelie's bird cage is shaped like a rectangular prism. The cage has a height of 26 inches and a volume of 7,280 cubic inches. Amelie puts a piece of newspaper on the bottom of the cage. The newspaper fits the bottom of the cage perfectly.
What is the area of the newspaper on the bottom of the cage?
Answer:
The area of the news paper which fits in the bottom of the Amile's cage is 280 square inches because The area is said to be the product of the two sides ( length an breadth ) of the rectangle.
The volume is said to be the product of the length, breadth and height of the cage.
Here the height and volume are given in the square inches.
volume = L* B *H = 7280 Square inches whereas height is 26 inches.
AREA = L* B = by bringing the height in divide with volume we can obtain the L* B value which is said to be the value of the height .
Step-by-step explanation:

What is the y-intercept of the line shown?
A. O
B. 1
C. 3
D. 3.5
Answer:
c 3
Step-by-step explanation:
the y intercept is where the line crosses the 0 x-axis
So ask yourself, what is the y when the x is 0?
on this one, the line crosses the 0 x-axis at 3 y
when the x is 0, the y is 3
So thats the y intercept

Ab has a midpoint of (2, 5)
A has coordinates of (1, 7)
whats the coordinates of B
Answer:
pt B = (3, 3)
Step-by-step explanation:
to get from (1, 7) to (2, 5) you move down two and to the right one
so from (2, 5) go down two and to the right one and you are at (3, 3)
A man spent 58% of his income and the amount of money left was $210 .Find his income.
Answer:
Step-by-step explanation:
First, subtract 58% from 100% to get 42%. That means $210 is 42% of this man's income.
Then, convert 42% into a fraction. This would be 21/50. Find the reciprocal of that, which is 50/21.
Now, multiply 50/21 by 210 to get the answer.
(50 * 210)/21
Multiply 50 by 210 to get 10500.
10500/21
(105/21) * 100 is the same as 10500/21.
Divide 105 by 21 to get 5.
5 * 100
Multiply 5 by 100 to get 500.
The man has a $500 income.
owen and needed to get his computer fixed he took it to the repair store the technician at the store worked on the computer for 5.5 hours and charged him $70 for parts the total is $702.50 what was the total cost of labor per hour
To figure out this problem, let's set up an equation first to make it easier:
702.50 = 5.5x + 70
x = amount charged per hour
702.50 = 5.5x + 70
-70 -70
-----------------------------
632.5 = 5.5x
/5.5 /5.5
--------------------
115 = x
Owen was charged $115 per hour

Step-by-step explanation:
write an equation for the nth term of the arithmetic sequence -7, -2, 3, 8...
Answer:
33
Step-by-step explanation:
An arithmetic sequence has a definite pattern. If we look at the number -7 and -2, what do we have to do to get from -7 to -2? We just have to add 5. To check this, we can add 5 to -2 and it will be 3.
Now, we know what the pattern is. Now, we have to find the ninth term using this pattern.
8 is the fourth term. So, 5 + 8 is 13. 13 is the fifth term. 13 + 5, is 18. 18 is the sixth term. 18 plus 5 is 23. 23 is the seventh term. 23 plus 5 is 28. 28 is the eighth term. Finally, 28 plus 5 is 33. 33 is the ninth term.

Is this correct or no
Answer:
Incorrect
Step-by-step explanation:
The correct answer is A.
The slope-intercept form is y-y₁=m(x-x₁)
The problem with B is that if you take out the coordinates for x₁ and y₁, you get the coordinates (1,4). This coordinate does not land on the line.
The coordinates for A is (-1,4). This point does land on the line.

Complete question :
The manager of Pia’s Taco Casa makes a deposit into the restaurant’s checking account at the end of the day. She has 2 fifty-dollar bills, 16 twenty-dollar bills, 4 ten-dollar bills, 1 five-dollar bill, 24 quarters, 12 dimes, and 3 nickels. She wants to receive 20 one-dollar bills to use as change the next day. How much is the total deposit
Answer:
$452.35
Step-by-step explanation:
1 Nickel = 25 cents = $0.25
1 dime = 10 cent = $0.10
1 quarter = 5 cent = $0.05
Notes deposited :
2 fifty-dollar bills = $50 * 2 = $100
16 twenty-dollar bills = $20 * 16 = $320
4 ten-dollar bills = $10 * 4 = $40
1 five-dollar bill = $5 * 1 = $5
24 quarters = 24 * $0.25 = $6
12 dimes = 12 * $0.1 = $1.2
3 nickels = 3 * $0.05 = $0.15
Total deposit :
$(100+320+40+5+6+1.2+0.15) =$472.35
Amount to withdraw:
20 $1 bill = $1 * 20 = $20
Net deposit :
Deposit - withdraw
$472.35 - $20
= $452.35

alan is spreading fertilizer on a field to get it ready for planting. The directions say to use 4/5 of a quart of fertilizer for each acre of land. Alan has two fields, one that is 22 1/2 and one that is 38 1/4. How much total fertilizer will Alan need for his two fields?
Answer:
48.6 quart of fertilizer
Step-by-step explanation:
The directions say to use 4/5 of a quart of fertilizer for each acre of land.
Alan has two fields,
Field 1
22 1/2 acre of land
1 acre of land = 4/5 quart
22 1/2 acre of land = x
Cross Multiply
x = 22 1/2 × 4/5
x = 45/2 × 4/5
x = 18 quart of fertilizer
Field 2
38 1/4 acres of land
1 acre of land = 4/5 quart
38 1/4 acre of land = x
Cross Multiply
x = 38 1/4 × 4/5
x = 153/4 × 4/5
x = 30.6 quart of fertilizer
The total fertilizer that Alan will need for his two fields is calculated as:
18 quart of fertilizer + 30.6 quart of fertilizer
= 48.6 quart of fertilizer
120 men and 80 women were asked if they drive to work.
Altogether 1/4 of the people said yes.
1/3 of the men said yes.
What fraction of the women said yes?
Answer:
1/8 of the women said yes
Step-by-step explanation:
Answer:
1/8
Step-by-step explanation:
In total there is 200 people (120+80)
1/4 of that is 50 people, keep this for later.
1/3 of 120 men is 40.
Subtract the men that said yes from the people that said yes. We get 10 women said yes.
If we put 10 over 80 (10/80) we can simplify that by reducing by 10, so 1/8 of the women said yes
