Answer:
a. (x+5)^2 = 49
b. (x+7)^2 = (x+1)^2
Step-by-step explanation:
So the term "a number" is always going to be x. input x into the sentences. "X plus five, then squared, is forty-nine". when they do "is __", that means equal to. In the second question, seven more than x is x + 7 (the two numbers are interchangeable here). Equivalent also means equal. hope this helped :)
Answer:
a: x + 5^2 = 49
b: 7>x^2=(put three lines not two) (1>x)^2

What is market shares?When some amount of money is used to buy the share of a particular company, then the percentage of total sales generated by that company is called the market share.
A financial analyst collects data over the next month to evaluate her model. At the end of the month, she finds that for one of the companies, the difference between her model and the data is 5%. She decides to collect data for an additional two months.
If the model is valid, then she can assume that her assumptions are correct over the model according to the data. It will result in decreasing the bridge gap between the model and the collected data.
Therefore, If her model is valid, she expect from the total data collected after three months that the difference between the data and the model will get smaller. The correct option is A.

The area of a floor in square yards is one-ninth the area of the floor in square feet. Write an equation representing y, the area in square yards, to f, the area in square feet.
HELP ME
Answers
Answer:
y = f/9
Step-by-step explanation:
Area of a floor in square yards = y = f/9
Area of a floor in square feet = f
The number that represents the area of the floor in square feet is 9 times the number representing the area in square yards. This makes sense because the ratio of yard to feet is 1 : 3 and the ratio of square yard to square feet is the same ratio but squared so 1 : 9.
If y represents the area in square yards and f the area in square feet.
y = f/9

Which pair of angles are Complementary Angles?
45 degrees and 95 degrees
or
38 degrees and 42 degrees
or
30 degrees and 51 degrees
or
63 degrees and 27 degrees
Answers
Answer:
63 degrees and 27 degrees
Step-by-step explanation:
Complementary angles are when two angles add to 90 degrees.
So, we can check if these pairs add up to 90 degrees.
45 + 95 = 140
38 + 42 = 80
30 + 51 = 81
63 + 27 = 90
The only pair of angles that are complementary is 63 degrees and 27 degrees.

save per CD?
Original unit cost of CDs = $_________ per CD
10% of original cost = $_________
Original cost minus the 10% discount = $_______
Discounted unit cost of CDs = $_______ per CD
Subtract the two unit costs to find
how much saved per CD = $_________
Answers
Answer:
Original Cost = $1.50 per CD
Discount = $1.50
Discounted Cost = $13.50
Discounted Cost = $1.35 per CD
You Saved = $0.15 per CD
Step-by-step explanation:
$15/10CDs = $1.50
$15x10% = $1.50
$15-$1.50 = $13.50
$13.50/10CDs = $1.35

Rhombus ABCD has vertices A(-1, -2), B(2,2), C(6,5), and D(3,1). The perimeter of the rhombus is
Answers
Answer:
The perimeter of the rhombus is approximately 19.999.
Step-by-step explanation:
First of all, we plot all points that constructs the rhombus, whose outcome is attached below. Diagonals of the rhombus are segments AC and BD, whose lengths are determined by Pythagorean Theorem:
Segment AC
[tex]AC = \sqrt{[6-(-1)]^{2}+[5-(-2)]^{2}}[/tex]
[tex]AC \approx 9.899[/tex]
Segment BD
[tex]BD = \sqrt{(3-2)^{2}+(1-2)^{2}}[/tex]
[tex]BD \approx 1.414[/tex]
The perimeter of the rhombus ([tex]p[/tex]) is calculated by the following equation:
[tex]p = 4\cdot \sqrt{\left(\frac{AC}{2} \right)^{2}+\left(\frac{BD}{2} \right)^{2}}[/tex]
[tex]p = 2\cdot \sqrt{AC^{2}+BD^{2}}[/tex]
[tex]p = 2\cdot \sqrt{9.899^{2}+1.414^{2}}[/tex]
[tex]p \approx 19.999[/tex]
The perimeter of the rhombus is approximately 19.999.

Answers
Answer:
Luis' skateboard will cost $76.32.
Step-by-step explanation:
Divide 79.91 by 100, this is what one percent is worth, .7991.
Multiply this by 12, giving you 12 percent, 9.59 (rounded to the nearest 10th).
Now subtract 9.59 from 79.91, 70.32. That is the price BEFORE tax.
Than divide 70.32 by 100, .7032.
Multiply this by 8.25, 5.80, this is tax.
Now add the price before tax, 70.32, to the tax, 5.80.
This creates 76.12. This means that the total price of the skateboard is $76.32.
Answer:
saving $10.38
tax $5.80
total pay $76.12
Step-by-step explanation:
79.91*0.12=9.59
79.91-9.59=70.32
70.32*0.0825=5.80
70.32+5.80=76.12
