In the parallelogram shown, AE = t + 2, CE = 3t − 14, and DE = 2t + 8. Parallelogram A B C D is shown. Diagonals are drawn from point A to point C and from point D to point B and intersect at point E. What is the length of line segment DB? 20 units 24 units 48 units 68 units
Answer:
48 units
Step-by-step explanation:
A parallelogram is a polygon with four sides. Opposite sides and opposite angles of a parallelogram are congruent.
The diagonals of a parallelogram bisect each other.
In parallelogram ABCD, AC and DB are the diagonals. Since the diagonals meet at E, hence:
AE = CE and DE = BE (diagonals of a parallelogram bisect each other).
Since AE = CE, hence:
t + 2 = 3t - 14
3t - t = 2 + 14
2t = 16
t = 8 units
Therefore DE = 2t + 8 = 2(8) + 8 = 24 units
DE = BE = 24 units
But DB = DE + BE
DB = 24 + 24
DB = 48 units
Answer:
The answer is 48 units
Step-by-step explanation:
A grocery store clerk put only packages of flour tortillas and packages of corn tortillas on a shelf. The ratio of the number of packages of corn tortillas to the total number of packages on the shelf was 7 to 16. Which number could represent the number of packages of flour tortillas the clerk put on the shelf?
Answer: 18
Step-by-step explanation:
The options are:
A. 23
B. 18
C. 14
D. 32
Since we are told that the ratio of the number of packages of corn tortillas to the total number of packages on the shelf was 7 to 16. This simply means that the ratio of flour tortillas to the total number of packages on the shelf was (16 -7 = 9) 9 to 16.
Therefore, to get the number that could represent the number of packages of flour tortillas the clerk put on the shelf we have to find the multiple of 9 in the question given . This will be:
Multiples of 9 = 9, 18, 27, 36, 45 ....
Based on the option, the answer will be 18.
3. The diagonal of a rectangular field is 169 m. If the ratio of the length to the width is 12:5, find the:
(a) dimensions;
(b) perimeter of the field.
The dimensions are 156m and 65m
The perimeter is 442m.
What are the dimensions?The formulae that can be used to determine the dimensions when the ratio of the dimensions are given and the diagonal is given are:
h = [tex]\frac{H}{\sqrt{ 1 + r^{2} } }[/tex]
w = [tex]\frac{Hh}{\sqrt{ 1 + r^{2} } }[/tex]
Where:
h = height H = hypotenuse r = ratio of width to the height : 5/12 = 0.41667w = widthh = [tex]\frac{169}{\sqrt{ 1 + 0.41667^{2} } }[/tex] = 156m
w = [tex]\frac{(169 x 156)}{\sqrt{ 1 + 0.41667^{2} } }[/tex] = 65m
The perimeter of a rectangle = 2(length + width)
2(156 + 65)
2(221) = 442m

A store marks up merchandise 27%. The original price of an item is $725. What will be the retail price?
Answer:
$168
Step-by-step explanation:
cause the store marks up the price by 115%
The original price of the item was $725
Store increases the margin by 27%
Let us assume the retail price to be x
To get the retail price we need to add the margin added by the store to the original price which is $725 in this case.
So,
x= 725 × 127/100
x= 92075/100
x= 920.75
Another method-
Let retail price be x
Since the original price of the item is $725
The store increases the price by 27%
Add 27% of $725 to the original price to get the retail price
725 × 27/100
= $195.75
Add 195.75 to the original price to get the retail price
x= 195.75+ 725
x= 920.75
The Retail price which will be charged by the store on the merchandise will be $920.75

In the diagram below of triangle ABC, D is a midpoint of AB and E is a midpoint
of BC. If m
of ZCAD?
Answer:
The measure of ∠CAD is 69°
Step-by-step explanation:
In ΔABC
∵ D is the mid-point of AB
∵ E is the mid-point of BC
∴ DE is parallel to AC
→ From parallelism
∵ DE // AC
∴ m∠EDB = m∠CAD → corresponding angles
∵ m∠EDB = 83 - 7x
∵ m∠CAD = 7x + 55
→ Equate them
∴ 7x + 55 = 83 - 7x
→ Add 7x to both sides
∵ 7x + 7x + 55 = 83 - 7x + 7x
∴ 14x + 55 = 83
→ Subtract 55 from both sides
∵ 14x + 55 - 55 = 83 - 55
∴ 14x = 28
→ Divide both sides by 14
∴ x = 2
→ To find m∠CAD, substitute x by 2 in its measure
∵ m∠CAD = 7(2) + 55
∴ m∠CAD = 14 + 55
∴ m∠CAD = 69°
∴ The measure of ∠CAD is 69°

(x+1)(x+8) is the expression which has an equivalent value to x² + 9x +8 for all values of x.
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is x² + 9x +8.
We have to find the equivalent expression to the expression x² + 9x +8.
Let us use the factorized form of the expression.
x² + 9x +8.
x² + 8x+x+8
Take common terms and factorize
x(x+8)+1(x+8)
(x+1)(x+8)

Data from the device show that the whale swam at a constant rate for 5 minutes and covered 2.5 miles in that time. Make a graph showing the change in the whales distance over time. How far does the blue whale swim in 1 minute? this 25 mi: 5
The graph showing the change in the whales distance over time is given by y = 0.5x
How to solve an equation?An equation is an expression that shows the relationship between two or more numbers.
The standard form of a linear equation is:
y = mx + b
Where m is the rate of change and b is the y intercept.
Let y represent the total distance covered for x minutes.
Let the constant rate be m miles per minute. The whale swam at a constant rate for 5 minutes and covered 2.5 miles in that time. Hence:
2.5 = 5(m)
m = 0.5 miles per minute
y = 0.5x
In 1 minute:
y = 0.5(1) = 0.5 miles

Amy is putting a new floor in her bathroom. She created a scale drawing of her bathroom floor using a scale of 1/3 inch= 1 foot. In the drawing, the bathroom measure 3 inches by 3 1/3 inches. Amy is purchasing squares tiles that measure 1/3 foot on each side. The cost of each tile is $3.00. How much will Amy pay for the tiles for bathroom floor
Answer:
$2,430
Step-by-step explanation:
Scale of the drawing = ⅓ in. to 1 ft
Measurement of the bathroom on paper = 3 in. by 3⅓ in.
Actual measurement of the bathroom:
3*3 = 9 ft
3⅓ * 3 = 10 ft
Area of the bathroom = 9*10 = 90 ft²
Let's find how many square tiles would cover 90 ft².
The side length of 1 tile is said to be ⅓ ft.
Therefore, the area of 1 tile would be ⅓*⅓ = ⅑ ft².
Number of tiles that would cover 90 ft² would be:
90/⅑ = 90*9
= 810 tiles
If 1 tile cost $3.00, therefore 810 tiles would cost:
810 * 3 = $2,430.
