Answer:
6.79
Step-by-step explanation:
First of all, you will have to know how much is 3% of 7 in order to decrease it by that amount.
7 x 0.03 = 0.21
Now that you know the amount, you can subtract it from seven and therefore you have decreased 7 by 3%.
7 - 0.21 = 6.79
Answer:
Percentage decrease = 7 × 3%
7 - Percentage decrease = 7-(3% x 7)= 7 - 3% x 7=7 x (1 - 3%)= (100% - 3%) × 7 = 97% x 7 = 679%

What is the area of the composite shape?
Answer:
290[tex]mi^{2}[/tex]
Step-by-step explanation:
You can divide this shape in a variety of ways, but I am going to divide it into a rectangle and a square. First, to find the area of the square, multiple 6 by 5, and get 30[tex]mi^{2}[/tex]. Next, to find the area of the big rectangle, multiply 20 by 13 and get 260[tex]mi^{2}[/tex]. Finally, add 30 and 260 and get a final answer of 290[tex]mi^{2}[/tex].

Answer:
1. x = 65
2. x = 40
3. x = -7
4. x = -4
5. x = -7
6. x = 4
Step-by-step explanation:
Angles in a triangle always add up to 180 degrees.
Thus, for each triangle you can write an equation setting the sum of the three angles equal to 180, and solving for x.
1. 180 = 80 + 35 + x
180 - (80 + 35) = x
180 - 115 = x
65 = x
2. 180 = 70 + 70 + x
180 - (70 + 70) = x
180 - 140 = x
40 = x
3. 180 = 76 + 41 + (x+ 70)
180 - (76 + 41) = x + 70
180 - 117 = x + 70
63 = x + 70
63 - 70 = x
-7 = x
4. (the red square means its a right angle = 90 degrees)
180 = 90 + 25 + (x + 69)
180 - (90 + 25) = x + 69
180 - 115 = x + 69
65 = x + 69
65 - 69 = x
x = -4
5. 180 = 50 + (57 +x) + (x + 87)
180 - 50 = (57 +x) + (x + 87)
130 = (57 +x) + (x + 87)
combine like terms
130 = 144 + 2x
130 - 144 = 2x
-14 = 2x
-7 = x
6. 180 = 80 + (9x + 4) + (16x - 4)
180 - 80 = (9x + 4) + (16x - 4)
100 = (9x + 4) + (16x - 4)
combine like terms
100 = 25x + 0
100 = 25x
4 = x

x = 15/27
Answer:
27x - 15 is your expression
Step-by-step explanation:

Use the following information to answer the question.
A laundry basket has 24 t-shirts in it. Four are navy,
12 are red, and the remaining are white.
1 point
1. What is the probability of randomly selecting a red shirt
Answer:
The probability is 1/2.
Step-by-step explanation:
There are 24 T-shirts in total and 12 is half of 24, the probability is 1/2.
I'm not sure about answer...
The probability of randomly selecting a red shirt is 50%.
Step-by-step explanation:
To figure this out, separate the total number of shirts into fractions based on the color. So for example, it would look something like this: Navy shirts are 4/24, Red shirts are 12/24, and White shirts are 8/24. The probability for each of the colors would be; Navy-16.666 percent, Red-50 percent, White-33.333 percent. Since we are only looking for the probability of selecting a Red shirt, the probability would be 50%.

20. Rafael has a business selling computers. He buys computers from the manufacturer for $450
each and sells them for $800. Each month, he must also pay fixed costs of $3000 for rent and
utilities at his store. If he sells n computers in a month, which of the following equations can be used
to calculate his profit?
A. P = n(800 - 450)
B. P = n(800 - 450 - 3000)
C. P = 3000n(800 - 450)
D. P = n(800 - 450) - 3000
E. P = n(800 - 450) + 3000
Yeah
Answer: D , p = n (800 - 450) - 3000
Step-by-step explanation: Firstly, you have to account for how much money Rafael is making off of each computer (800 - 450). That factor is then multiplied by the variable "n" which represents the amount of computers sold. Lastly, since this is an equation to calculate his monthly profits, you have to subtract the rent that he is paying ($3000) from the total profit that he made off of selling the computers. Therefore, giving you the equation
P (profit) = n (amount of computers sold) (800-450) - 3000 (rent).
The equation that represents Rafael's monthly profit selling 'n' numbers of computers is D. P = n(800 - 450) - 3000.
What is an equation?An equation represents equality for the terms that are on the both side of the equal sign.
Given Rafael buys computers for 450 dollars and sells them for 800 dollars each.
He also had to pay 3000 dollars for rent and utilities for the store and the number of computers sold in each month is given by 'n'.
∴ The equation that represents his profit(P) in a month is,
P = n(800 - 450) - 3000.
