BCD = 90˚
ABD = 16˚
CBE = 74˚
ADE = 74˚
AEB = 148˚
DEA = 32˚
Step-by-step explanation:
BCD: I suppose that’s a rectangle, and all rectangles have four right (90˚) angles.
ABD: alternate interior angles are congruent, so ABD is congruent to BDC (16˚).
CBE: Complementary angles add up to 90˚, so just subtract ABD (16˚) from 90˚ to equal 74˚.
ADE: Same this as CBE for same reason.
AEB: You need to find DEC first for this. To find DEC, add BDC and ACD together to get 32˚, then subtract that from 180˚ to find the answer (148˚). This is because all triangles have a 3 interior angle measure sum of 180˚. (And vertical angles are congruent).
DEA: Subtract AEB from 180˚ because they’re supplementary angles.

It takes William 14 minutes to run two laps around the lake. How many laps can William
complete in 56 minutes
Answers
7 minutes per lap
56/7 is 8
8 laps hope this helps
Answer:
8 laps
Step-by-step explanation:
this is pretty simple you just take the total time (56min) and then you take how long it takes William to run two laps around the lake (14min). then you try and figure out how many minutes it takes william to run one lap around the lake so you take 14 and divide it by 2 and that gives you 7.
therefore you take 56 and divide it by 7 and that gives you the answer of 8 laps william can run in a total of 56 min.

expand and simplify {3x+2}{x-1}
Answers
Answer:
{3x+2}{x-1} = 3x²-x-2
Step-by-step explanation:
The given expression is :
{3x+2}{x-1}
We can solve it as follows :
{3x+2}{x-1} = 3x(x)+3x(-1) +2(x) +2(-1)
= 3x²-3x+2x-2
= 3x²-x-2
So, the expand form of the given expression is 3x²-x-2.

What is the area of the given composite shape?
Answers
Answer:
choice A; 128.52 square feet
Step-by-step explanation:
This shape is made up of a semi-circle and a rectangle. The area of the rectangle will be 12*6 = 72 sq ft.
The formula for area of a circle is [tex]\pi[/tex]*[tex]r^{2}[/tex]. also r=radius. We are given the diameter, 12 feet. The radius is diameter/2, so the radius of the circle will be 6 feet.
Since pi is infinite we round it to 3.14.
Plug in the values and our expression will be (3.14*[tex]6^{2}[/tex])/2 because it is a semi-circle. Simplify that to (3.14*36)/2 = 113.04/2 = 56.52 sq ft.
Remember to add the area of the rectangle and semi-circle. 72 + 56.52 = 128.52 sq ft.

Answers
Answer: - 1/x or [tex]-\frac{1}{x}[/tex]
Step-by-step explanation:
(-3x^2 /3 ) * (4x^3 / 4)
=> - (3x^3 / 4) * (4x^3 / 3)
=> - (x^2 * 4) / 4x^3
=> - (x^2 / x^3)

The product of the two numbers will be -6.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the two numbers are (-3x2/3) and (4x3/4).
To find the product of (-3 * 2/3) and (4 * 3/4), we first need to simplify each expression:
(-3 x 2/3) = -2
(4 x 3/4) = 3
Next, we multiply the two simplified expressions:
-2 x 3 = -6
So, the product of (-3 * 2/3) and (4 * 3/4) is -6.

Mark as brainliest if im correct pleaseA center-pivot sprinkler system operated by Colorado Land & Agriculture, Inc., is used to water the alfalfa in a circular field. The circumference of the field is 2 miles. As the sprinkler travels in an arc around the field, sprinkler nozzles get clogged and must be cleaned. The distance around the circumference of the field from the starting point to the point when a nozzle becomes clogged is the value of a random variable X that is uniformly distributed over the 2-mile circumference of the field. As a part of a simulation comparing farm maintenance policies, an input is the point at which sprinklers become clogged. If a random number 0.724 is generated, at what distance from the starting point would we simulate that a nozzle becomes clogged? Give your answer to 3 decimal places.
Answers
Answer:
The answer is "1.448 miles".
Step-by-step explanation:
X= The distance to both the nozzle clogged from of the starting point.
X [tex]\sim[/tex] Uniform(0,2) miles.
They are simulating the random number Y=0.724, and the Y has both a distribution uniform(0,1). Therefore 2Y is distributed evenly (0.2). And They model the clogging of its nozzle at 2Y=1.448 miles

What percentage of his monthly budget does Doug put in savings?
O A. 13%
B. 6%
C. 11%
D. 16%
To get the percentage of his monthly budget does Doug put in savings, first we need to get the total savings
Total savings = 403+806+868+496+341+186
Total money = $3100
Amount spent on savings = $341
Percentage savings = amount spent on savings/Total money × 100%
Percentage savings = 341/3100 × 100
Percentage savings = 341/31
Percentage savings = 11%
Hence the percentage of the total money spent on savings is 11%
