Write a polynomial in standard form that represents the area of the shaded region.
Answers
Answer:
Area of the smaller square is x * x, which is x^2
Area of the larger square is (x + 7)(x + 7), which is x^2 + 14x + 49
The area of the shaded area = Area of the larger square - Area of the smaller square
Area of the shaded region = x^2 + 14x + 49 - x^2
Area of the shaded region is 14x + 49.

Celia used celery, carrots, and tomatoes in a recipe. Use the clues to find the amount of each ingredient she used. CLUE 1: The amounts were 2/5 cup, 3/4 cup, and 5/8 cup. CLUE 2: There is less celery than tomatoes. CLUE 3: There is less tomatoes than carrots.
Answers
Answer:
Celery = 3/8 cups
Tomatoes = 2/5 cups
Carrot = 5/4 cups
Step-by-step explanation:
CLUE 1: The amounts were 2/5 cup, 3/4 cup, and 5/8 cup
CLUE 2: There is less celery than tomatoes.
CLUE 3: There is less tomatoes than carrots
From clue 2 and 3:
Tomato > Celery ; Carrots > tomatoes
From least to highest :
Celery < Tomatoes < Carrot
Arranging clue 1 in ascending order :
2/5 = 0.4
3/8 = 0.375
5/4 = 1. 25
Hence,
3/8 < 2/5 < 5/4
Celery = 3/8 cups
Tomatoes = 2/5 cups
Carrot = 5/4 cups
The table shows the balance of an account each year.
Years Balance
0 $40
1 $42
2 $44
3 $46
What is the interest rate of the account? What is the balance after 10 years?
Answers
Answer:
The interest rate is $2, the balance after 10 years will be $60.
Step-by-step explanation:
Each year the balance of the account increases by $2, so that would be the interest rate. After 10 years, the account will have 40 + 2 * 10 which equals $60.

A shop makes £2,750 in March. It has an Easter sale and the profit for April is £3,162.50 Work out the percentage increase
Answers
Answer: 15%
Step-by-step explanation:
From the question, we are informed that a shop makes £2,750 in March while it made £3,162.50 in April. The increase will be:
= £3,162.50 - £2,750
= £412.50
Percentage increase = £412.50/ £2750 × 100
= 15%
Rodrigo practiced playing the guitar 15 1/3 hours over the past 3 weeks.
He practiced for 5 1/4 hours during the first week and 5 2/3 hours during the second week.
How much time did Rodrigo spend practicing during the third week? Use the numbers and symbols to select the equation that represents the problem. Then solve the equation. Symbols may be used more than once or not at all.
15 1/3, 5 1/4, 5 2/3, x, =, and +.
The equation that represents the problem is
a. 15 1/3 = x - 5 1/4 - 5 2/3
b. x = 15 1/3 + 5 1/4 + 5 2/3
c. x + 15 1/3 = 5 1/4 + 5 2/3
d. 15 1/3 = 5 1/4 + 5 2/3 + x
Answers
Answer: d. 15 1/3 = 5 1/4 + 5 2/3 + x
Step-by-step explanation:
15 1/3 (total) = 5 1/4 (first week) +5 2/3 (second week) +x (third week)
When you add the amount of time Rodrigo practiced each week, you get the total amount of time he practiced

Whats 8 2.5% of 75?Write your answer as a decimal.

Decimal =
0.875
Explanation:
The answer that has already been given is perfect in and by itself. I just want to give you some methods for doing these type of questions so that you won't stagger when you see these type of questions in exams (like the SAT).
Whenever you see such questions, remember the following things. These are conversions of English words to Mathematical tools.
What
=
Any variable like
x
Percent / Percentage / %
=
Divide by 100
of

Put an equal to (

) sign
I'll give you an example through a question.
What percent of 200 is 5?
Ans: Replace English words by mathematical tools according to the rules I told you.
x
( What) /100 ( percent)
×
( of) 200
=
( is) 5
In a refined form,
x
100
×
200
=
5
Calculate x. On calculating, x comes out to be
2.5
So, 2.5 percent of 200 is 5.
Now your question is actually very simple if you follow my rules.
You want 87.5%. By the rules, % means divided by 100. So
87.5
%
=
87.5
100
and now using the same strategy, Ans:

Disregard the next section if you know how to convert a decimal to a fraction
Section Starts
First, I'll write the decimal form. Whenever you divide by a number that is in form of 1 followed by
n
number of zeroes. (here 1 is followed by 2 zeroes), you should shift the decimal point to the left side by n places.
In this case, shift decimal point in 87.5 to the left by 2 places. So this becomes 0.875.
This is the answer in decimal point.
Now simultaneously, I'll teach you how to convert a decimal into a fraction.
Here, you see 2 types of "numbers". One to the left side of the decimal point and one to the right side of the decimal point.
Here, left side of decimal point is 0 and right side of decimal point is 875.
Count the number of digits in the number to the right side of the decimal point (Here, the number of digits is 3)
Remove the decimal point and divide the number by a number formed by 1 followed by the "digits" we obtained (i.e. 3).
So, 875/1000. Simplify this, and you get your answer.

⅕m - 12 = -32
could someone solve this
Answers
Answer:
m = -100
Step-by-step explanation:
(1/5)m -12 = -32
add 12 on both sides
(1/5)m = -20
multiply both sides by 5
m = -100
Answer:
m = -100
Step-by-step explanation:
So in order to solve this equation we are going to have to convert 1/5m to a decimal, this will make it easier to solve the equation:
1/5m = 0.2m
Next we are going to take our 0.2m and place it within the equation where 1/5m is:
⅕m - 12 = -32 or 0.2m - 12 = -32
So now we are going to add 12 to both sides of the equal sign in the equation to segregate the 0.2m within the equation:
0.2m - 12 = -32 or 0.2m + (-12 + 12) = (-32 + 12)
making the equation look like this:
0.2m = -20
now we are going to divide 0.2 from both 0.2m and -20 to get the value of m:
0.2m/0.2 = -20/0.2
Thus getting the answer:
m = -100
So how do we know that -100 is the value of m? well we check our work of course by substituting -100 in place of m!
⅕(-100) - 12 = -32 or 0.2(-100) - 12 = 32
0.2(-100) - 12 = 32
-20 - 12 = -32
-32 = -32
