A jacket that costs $18 is sold to the customer for $25.
A hat that costs $8 is sold to the customer for $12.
A pair of shoes that costs $20 is sold to the customer for $35.
A shirt that costs $12 is sold to the customer for $20
Answers
Answer: A pair of shoes that costs $20 is sold to the customer for $35, and A shirt that costs $12 is sold to the customer for $20.
Step-by-step explanation:
1. Half (or 50%) of 20 is 10, so 20+10=30, but 35 is bigger than 30.
2. Half (or 50%) of 12 is 6, so 12+8=18, but 20 is bigger than 18.

HELP, DUE IN 15 MINUTES! In triangle ABC, the measure of ∠B is 90°, BC=16, and AC=20. Triangle DEF is similar to triangle ABC, where vertices D, E, and F correspond to vertices A, B, and C, respectively, and each side of triangle DEF is \(\frac{1}{3}\)
the length of the corresponding side of triangle ABC. What is the value of sinF?
Answers
Answer:
Triangle ABC is a right triangle with its right angle at B. Therefore, AC is the hypotenuse of right triangle ABC, and AB and BC are the legs of right triangle ABC. According to the Pythagorean theorem
Step-by-step explanation: AB=202−162=400−256=144=12
Since triangle DEF is similar to triangle ABC, with vertex F corresponding to vertex C, the measure of angle∠F equals the measure of angle∠C. Therefore, sinF=sinC. From the side lengths of triangle ABC,
sinF=oppositesidehypotenuse=ABAC=1220=35
Therefore, sinF=35.
The final answer is 35 or 0.6.

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

Answer: D
Step-by-step explanation:
REFERENCE:
- An Integer is simply a whole number.
- Here, you have square roots. "Perfect squares" are square roots in which the square root of the number is an integer , or whole number.
__________
The perfect squares up to 100 are:
√1= 1 ( 1x1=1)
√4= 2 (2x2=4) and so on
√9= 3
√16= 4
√25= 5
√36= 6
√49= 7
√64= 8
√81= 9
√100= 10
____________
Now let's look at the answer choices:
A. √3. This is not an integer because the square root of 3 is a long decimal, 1.73205081. That's not a whole number.√3 is not in the list of perfect squares
B. √6. Not an integer. the square root of 6 is 2.44948974278. √6 is not listed in the perfect squares
C. √15 is 3.87298334621, which is not an integer. Not listed in the perfect squares.
D. √36 IS an integer. The square root of 36 is 6, which is a whole number. √36 is also listed in the perfect squares list. I know the square root of 36 is 6 because 6x6=36.
Answer= D

Which ordered pair is a solution to the system of linear equations? x + 2y = 2 y = −2x − 2 (−2, −2) (−2, 2) (2, 2) (2, −2)
Answers
Answer
to solve, plug the value of the variables in each equation in the system
(1,2) means x = 1 and y = 2
y = -2x + 4
2 = -2(1) + 4
2 = -2 + 4
2 = 2
the ordered pair is a solution to the first equation
7x - 2y = 3
7(1) - 2(2) = 3
7 - 4 = 3
3 = 3
the ordered pair is a solution for the second equation
Because the ordered pair is a solution for BOTH equations in the system, it is a solution to the system. Therefore, the correct answers are:
"When (1,2) is substituted into the first equation, the equation is true."
"The ordered pair (1,2) is a solution to the system of linear equations."
"When (1,2) is substituted into the second equation, the equation is true."

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
Answers
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)
