Answer:
r = -4
Step-by-step explanation:
-1.5(4-r)=-12
Divide each side by -1.5
-1.5/-1.5(4-r)=-12/-1.5
(4-r)=8
Subtract 4 from each side
4-r-4 = 8-4
-r = 4
Divide each side by -1
r = -4

Steve buys a wallet that costs $35.00. He pays 10% sales tax. How much does he pay for the wallet with tax?
A. $48.50
B. $38.50
C. $18.50
D. $45.50
Answer:
B. $38.50
Step-by-step explanation:
The original price of item (before tax) is 100% of the price of the item since 100% means the whole amount.
The tax is 10% of the original price, so add 10% to 100% making it 110%.
The total price including tax is 110% of the original price.
We need to find 110% of $35.00.
To find a percent of a number, multiply the percent by the number.
110% of $35.00 = 110% * $35.00
Change the percent to a decimal by moving the decimal point two places to the left.
110% becomes 1.10 as a decimal
110% of $35.00 = 110% * $35.00 = 1.10 * $35.00 = $38.50
Answer: B. $38.50

find the perimeter and area of the shaded region.
Answer:
Area=576 cm²
Perimeter=123.4 cm
Step-by-step explanation:
We have to assume that ABCD would form a square and not a rectangle. If so, the area is simple: 24x24=576 (Just picture the half circle sliding into the empty space - it’s the same area.)
For the perimeter, we find it for the half circle first. 1/2(2)[tex]\pi[/tex](12)=37.7
Then add the top and bottom (24 and 24) to the left and right (37.7 And 37.7)
24+24+37.7+37.7=123.4

PLS HELP ME WITH THIS QUESTION, ANYTHING REALLY HELPSS!!!!
Answer:
x = 75
Step-by-step explanation:
FGE is a straight line so it equals 180 degrees
FGA + AGC + CGE = FGE
x + 90 + 15 = 180
Combine like terms
x+ 105 = 180
Subtract 105 from each side
x = 180-105
x = 75
Answer:
x = 75º
Step-by-step explanation:
The Vertical Angle Theorem shows that:
∠CGE ≅ ∠DGF
So:
∠DGF = 15º
∠AGD = 90º
90º - 15º = 75º
x = 75º

Consider that ALMN is similar to APQR and the measure of ZP is 80°. What is the measure of 2L?
A) 20
B) 70
C) 80
D) 90
Answer:
80°
Step-by-step explanation:
as ALMN is similar to APQR thus L and P are similar too.measure of ZP =80° i.e. 80 ÷2 = 40° for each Z and P.now P =40° (so L =40° ) , then 2L = 2 × 40° = 80°Annie tried to solve a problem step by step: 7.5 + k = 10 7.5 + k - 7.5 = 10 - 7.5 step 1 k = 2.5 step 2 Find Annie's mistake: A. Step 1 B. Step 2 C. Annie did not make a mistake
Answer:
(C) Annie did not make a mistake
Step-by-step explanation:
To isolate the variable k in the equation [tex]7.5 + k = 10[/tex], we'd have to subtract 7.5 from both sides so we just had k on one side.
This is exactly what Annie did, and therefore, her answer is correct.
Hope this helped!
Answer:
C. Annie did not make a mistake
Step-by-step explanation:
Substitute 2.5 for k in the equation and see if it is correct
Each time you substitute you should see that Annie answered the equation correctly

Answer:
x = 22.62°Step-by-step explanation:
To find the measure of angle x we use cosine
[tex] \cos( \alpha ) = \frac{adjacent}{hypotenuse} [/tex]
From the question
PO is the hypotenuse = 13
The adjacent is 12
Substitute the values into the above formula
That's
[tex] \cos(x) = \frac{12}{13} [/tex]
[tex]x = \cos^{ - 1} ( \frac{12}{13} ) [/tex]
x = 22.6198
We have the final answer as
x = 22.62° to the nearest hundredthHope this helps you
Answer:
Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of X. All of the angles of an equilateral triangle are equal.

kristen and melissa spent 35% of their $32 on movie tickets. how much money did they spend
Answer:
11.2$
Step-by-step explanation:
Kristina and Melissa had 32$ at total
● 32$ => 100%
They have spent 35%
Let x be that amount
● x => 35%
●32 => 100
● x => 35
● x = (35×32)/100 = 11.2$
They have spent 11.2$
Answer:
They spent $20.80
Step-by-step explanation:
Since they had $32 and spent 35% of it you would do 32 * 35%
then you would get 11.2
now that is not the answer because that is just what 35% of 32 is
to get the answer you would then subtract 11.2 from 32 to get 20.8
and since this is a matter of money you would write 20.8 as $20.80.

7. Assume two people, Swanson and Suzie, are standing 35 feet apart and are watching a boat
race. At a given moment, Swanson approximates the angle formed by the lead boat, himself, and
Suzie to be 30°. Suzie approximates the angle formed by the lead boat, herself, and Swanson to be

35 feet
Swanson
Suzie
Part I: What is the missing angle in this triangle? (1 point)
Part II: Use the law of sines to find the distance from Swanson to the boat. (2 points)
Answer:
78.4 ft
Step-by-step explanation:
Part I:
Missing angle = 180° - (130 + 30) (sum of angles in a triangle)
= 180° - 160°
Missing angle = 20°
Part II: distance (d) from Swanson to the boat
Law of Sines is given as:
[tex] \frac{a}{sin(A)} = \frac{b}{sin(B)} [/tex]
Where,
a = d
A = 130°
b = 35 ft
B = 20°
Plug in the values and solve for d
[tex] \frac{d}{sin(130)} = \frac{35}{sin(20)} [/tex]
Multiply both sides by sin(130) to make d the subject of the formula
[tex] \frac{d}{sin(130)}*sin(130) = \frac{35}{sin(20)}*sin(130) [/tex]
[tex] d = \frac{35*sin(130)}{sin(20)} [/tex]
[tex] d = 78.4 ft [/tex]

domain: {x | x > 4}; range: {y | y > –8}
domain: {x | x > –4}; range: {y | y > 8}
Answer:
None of the above
Step-by-step explanation:
A graph of the function f(x) = 4x- 8 is straight line passing through (0,-8) on y axis and (2,0) on x axis.

Answer:
y=15x+25, the cost is 205 dollars
Step-by-step explanation:
The simplest way to write a rule for this is to write it in slope intercept form, y=mx+b. Let y represent the cost of the membership. Every month the cost is 15 dollars. If we let x represent the months we can rewrite this as 15x. The one time cost is 25 dollars so we can just add that to the end of the equation. y=15x+25. There are 12 months in a year so we just have to substitute. y=15(20)+25=205 so the answer is 205 dollars.
