Answer:
Step-by-step explanation:
the answer is c
The statement must be true about parallelogram ABCD is BE ≅ DE option (C) BE ≅ DE is correct because the diagonals of a parallelogram bisect each other.
What is a Parallelogram?A parallelogram is a polygon with four sides, opposite sides of the parallelogram are parallel.
The parallelogram ABCD is shown in the figure.
A parallelogram is a type of quadrilateral,
The quadrilateral can be defined as the four-sided polygon in geometry having four edges and four corners.
The parallelogram has two diagonals, AC and BD.
From the property of Parallelogram,
The diagonals of a parallelogram bisect each other.
So, AC and BD bisect each other.
AE = ECBE = CE
The correct answer is BE ≅ DE.

They plan on buying 120 bouquets of flowers. The ratio of the number of bouquets of roses to the number of bouquets of sunflowers will be 5/3. How many bouquets of flowers did they buy?
Bouquet of Roses?
Bouquet of Sunflowers?
Answer: Roses= 75, Sunflowers= 45
Step-by-step explanation:
Add the ratios- 5 + 3 = 8
Divide the total by the sum = 120 ÷ 8 = 15
Multiply the ratios- 5 x 15 = 75 and 5 x 3 = 45
∴ 5:3 = 75 , 45

The segments shown below could form a triangle.
Answer:
A. True
Step-by-step explanation:
The Triangle Inequality Theorem says that the sum of any two sides must be greater than the third side. Let's see if this is true.
a + b
9 + 1 = 10>9
a + c
9 + 9 = 18>1
c + b
9 + 1 = 10>9
True, the segments shown below could form a triangle. Option A is correct.
What is the triangle?A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.
According to the Triangle Inequality theorem, any two sides' total must be bigger than the third side. Verify one by one;

Find the other endpoint of the line segment with the given endpoint and midpoint.
Find the distance between the two x values: -10 to -7 is 3 units, so add to the midpoint: -7 + 3 = -4
The x value is -4
Now do the same for y:
7 to -3 is 10 units
Because the midpoint is less than the end point subtract:
Y = -3 -10 = -13
Y = -13
The endpoint would be (-4, -13)

Answer:
x≤-3 2 ≤x<7
Step-by-step explanation:
(x^2+x-6) /(x-7) ≤0
Factor the numerator
(x+3)(x-2) / (x-7)≤0
Critical points are
X =-3 X =2 X=7
We need to check the values when
x≤3 -3 ≤ x≤2 2 ≤x<7 x>7
(x cannot be 7 because then the denominator is zero)
and see when it is less than 0
Substitute a value in and see if factor is positive or negative

600 feet of fence surround a rectangular playground that is 100 feet wide. How long is the playground? A.400 b.500 c.300 d.200
Answer:
A.400
Step-by-step explanation:
Well perimeter for a rectangle is l+l+w+w
100+100+l+l=600
200+2l=600
Subtract 200 from both sides
2l=400
Divide both sides by 2
l = 400 feet
The length of the rectangle is 400 feet long.

Step-by-step explanation:
Seth has just decided to replace his computer. His old computer cost him $1,433 when he bought it exactly seven years ago. Seth paid for it with his credit card, which has an APR of 11.70%, compounded monthly. He made no other purchases with the card and paid off his balance after two and a half years of making identical monthly payments. The computer consumed about $0.79 of electricity every day. In total, what percentage of the lifetime cost of the computer did the electricity make up? (Assume that two out of the seven years were leap years, and round all dollar values to the nearest cent.)
a.
82.157%
b.
58.500%
c.
21.718%
d.
54.898%
Please select the best answer from the choices provided.
A
B
C
D
Answer:
The answer is D
Step-by-step explanation:
The solution would be like this for this specific problem:
Cost of the computer:
i = 0.117 / 12
i = 0.00975
= monthly payment
= (i * P * (1 + i)^n) / ((1 + i)^n - 1)
= (0.00975 * $1433 * (1 + 0.00975)^30) / ((1 + 0.00975)^30 - 1)
= $55.32
Electricity cost:
= $0.79 * 365.25 * 7
= $2019.83
Electricity Percentage:
= $2019.83 / ($2019.83 + $1659.60)
= 54.89%
Electricity:
= ($0.79 * 365 * 5) + ($0.79 * 366 * 2)
= $2020.03
Electricity Percentage:
= $2020.03 / ($2020.03 + $1659.60)
= 54.898%
In total, the electricity made up 54.898% of the lifetime cost of the computer.

A painter is painting a rectangular wall that measures 22.8 ft by 17.3 ft. Each gallon can of paint covers 100 square feet. What are the fewest gallons needed to paint the wall?
____gallons
Answer:
1.548 gallons
Step-by-step explanation:
Length of the rectangular wall = 25.1 ft.
Width of the rectangular wall = 18.5 ft.
Area of the rectangular wall = length * width = 25.1 * 18.5
= 464.35 square feet
300 square feet wall can be painted using 1 gallon of paint.
=> 1 square feet wall can be painted using gallon of paint.
=> 464.35 square feet wall can be painted using gallon of paint.
= 1.548 gallons of paint
Answer:
4 gallons
Step-by-step explanation:
The first thing you want to do is times 22.8 * 17.3 = 394.44. Then what you want to do is see how much 100 square gallons can cover the area : 4. If we make it 3 it is going under if it is 4 it can cover the whole thing, and if we make it 5 we have a little much.

c. How many years will it take for the account to contain $2,500?
d. How many years will it take for the account to contain $3,000?
a. After 4 years, the amount in the account will be $
(Do not round until the final answer. Then round to the nearest cent as needed.)
Answer:
a. $ 2,431.01 = 4 years
b. $ 4,584.04 = 17 years
c. 4.57 years = $ 2,499.57
d. 8.3 year = $ 2,998.48
e. $ 2,431.01 = 4 years
Step-by-step explanation:
Compound Interest Equation
A = P(1 + r/n)nt
Where:
A = Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
R = Annual Nominal Interest Rate in percent
r = Annual Nominal Interest Rate as a decimal
r = R/100
t = Time Involved in years, 0.5 years is calculated as 6 months, etc.
n = number of compounding periods per unit t; at the END of each period

A student is asked to find the length of the hypotenuse of a right triangle. The length of one leg is 26
centimeters, and the length of the other leg is 24 centimeters. The student incorrectly says that the
length of the hypotenuse is 7.1 centimeters. Answer parts a and b.
a. Find the length of the hypotenuse of the right triangle to the nearest tenth of a centimeter.
Answer:
c ≅ 35.4 cm.
Step-by-step explanation:
To find the length of the Hypotenuse of a triangle, the formula a² + b² = c² will need to be used. Therefore:
26² + 24² = c² (c is the hypotenuse)
1252 = c²
√1252 = c
c ≈35.38
Round to tenths place:
c ≅ 35.4 cm. This is the Hypotenuse of the triangle.
