Answer:

Answer: A'Reana's weekly allowance is $100

Step-by-step explanation:

Backward Solution

To solve some problems, we can work backward, using the inverse operations, to arrive at the solution.

The problem explains a sequence of expenses A'Reana does with her weekly allowance. In the end, she had $37.50.

That final balance came when she last spent $7.50 on a pizza. Thus, before that, she had $37.50+$7.50=$45

This balance is half of her previously remaining money. The other half was spent on a new shirt. Thus she had 2*$45=$90.

Those $90 were left after she gave $10 to her friend Taylor, thus, the initial money was $90+$10 = $100

Answer: A'Reana's weekly allowance is $100

Acute triangle

Step-by-step explanation:

When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:

1) Square all 3 sides.

2) Sum the squares of the 2 shortest sides.

3) Compare this sum to the square of the 3rd side.

if sum > 3rd side:  Acute Triangle

if sum = 3rd side:  Right Triangle

if sum < 3rd side:   Obtuse Triangle

Answer:

The first option. "If lines on a coordinate plane have opposite reciprocal slopes, then they are perpendicular."

Step-by-step explanation:

It is the only one that makes sense, tbh. But, it includes the proper "if-then" form like the question requests it have. It also incorporates all aspects of the original statement-

a.) lines on a coordinate plane

b.) perpendicular

c.) opposite reciprocal slopes.

You're welcome. :D

Answer:

the height of the tree to the nearest tenth of a meter is 13.8 meters

Step-by-step explanation:

The computation of the height of the tree is shown below:

Given that

Distance from the tree is 10 meters

And, the angle of elevation of the tree is 54 degrees

Now here we used the trigonometry

[tex]tan \theta = \frac{Height}{distance} \\\\tan 54^{\circ} = \frac{height}{10}[/tex]

So, the height is

= 10 × 1.38

= 13.8 meters

hence, the height of the tree to the nearest tenth of a meter is 13.8 meters

Answer:

5(2x-8)+15=-15

10x-40+15=-15

10x-25=-15

    +25   +25 (add 25 to both sides)

____________

10x=10

divide by 10 on both sides

x=1

Answer:

x=1

Step-by-step explanation:

First youd distribute the 5 to the 2x-8 so that way you can combine like terms and make the equation smaller

10x - 40 + 15 = -15

combine the -40 and 15

10x - 25 = -15

add 25 to both sides to get 10x by itself on the one side. you have to add 25 to the -15 because the two sides must stay balanced

10x = 10

divide by 10 to get x by itself. you must divide since x is being multiplied by 10

x=1

Answer:

Step-by-step explanation:

7(3+4y)-15y=73

21 plus 28y-15y=73

21 plus 13y = 73

13y=51

y=4

Step-by-step explanation:

Step 1: Multiply the 7 into the bracket.(make sure that your signs are correct)

Step 2: Minus the 21 from the 73.( Because when you take a value over the equal sign the value's sign changes)

Step 3: Minus 15y from 28y.

Step 4: Divide 52 by 13( because when you take the 13 over it divides ,because on the other side lf the equal the 13 multiples with the y)

Answer:

321.

Step-by-step explanation:

The next term after 81 is 102 .

Between  102 and 198 inclusive we have  (198-102)  / 5  + 1 = 96/3 + 1 = 33 terms - these will all have at least one 1 and be divisible by 3.

So 198 = 6 + 33 = 39th term.

After 198 we have 201, 210, 213, 219, 231, 261, 291, 312, 315, 318, 321

The answer is 321..

Answer:-8,4 is ur answer

Answer:

+5

Step-by-step explanation:

Answer:

y = -1/2 x + 1

Step-by-step explanation:

(-2, 2) and (4, -1)  are points of the linear function, that will be described as:

y = ax + b

setting x=-2, y=2:

2 = -2a + b, so b = 2 + 2a

setting x=4, y=-1:

-1 = 4a + b ⇒ -1 = 4a + 2 + 2a ⇒   -3 = 6a ⇒ a = -1/2, b = 1

y = -1/2 x + 1

Answer:

No, there is no change in the relationship. The slopes of AC and DE continue to be equal, and the length of DE remains half of the length of AC.

Step-by-step explanation:

The answer is from Plato. I hope this helps :)

Answer:

No, the connection has not changed. The slopes of AC and DE are still equal, and the length of DE is still half that of AC.

Answer:

20%

Step-by-step explanation:

Cost of Shirt = $15.50

Cost for a pair of jeans = $32.00

Cost for a belt = $24.30

Total cost = $15.50 + $32.00 + $24.30 = $ 71.8

Given that, coupon discount = $14.36

To find:

The percentage off on the coupon.

Solution:

The percentage off will be calculated on the total cost.

[tex]\text{Percentage\ off} = \dfrac{Coupon\ discount}{Total\ Cost}\times 100\\\Rightarrow \text{Percentage\ off}= \dfrac{14.36}{71.8}\times 100\\\Rightarrow \text{Percentage\ off} = 0.2\times 100\\\Rightarrow \text{Percentage\ off} = \bold{20\%}[/tex]

Therefore, the answer is:

20%

Answer:

It would be negative. 10 subtracted by any number higher then 10 will always be negative. Make a number line and go backwards 19 if you need the help.

Step-by-step explanation:

Answer: It will be negative because 19 is greater than 10 and 19 itself  is being subtracted from 10.

Step-by-step explanation:

10-19  is equal to -9.

An example is using the number line to plot the solution,  you will start from 10  and move backwards 19 units because you are subtracting 19 from 10. If a bigger number is being subtracted from a smaller number, the solution will be always negative.

Answer: B, the area of interior square in step 2 is greater than the combined area of the two interior squares in step 1.

Step-by-step explanation: I took the quiz and got it right

The area of the interior square in step 2 is greater than the combined area of the two interior squares in step 1. Then the correct option is B.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

These two images show steps in the proof of the Pythagorean theorem.

The area of the interior square in step 2 is greater than the combined area of the two interior squares in step 1.

Then the correct option is B.
