Answer:
m∠B = 43°
b = 26.1
c = 38.3
Step-by-step explanation:
By applying triangle sum in the given triangle,
47° + 90° + m∠B = 180°
137° + m∠B = 180°
m∠B = 43°
By applying sine ratio to the angle measuring 47°.
sin(47°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{28}{c}[/tex]
c = [tex]\frac{28}{\text{sin}(47^{\circ})}[/tex]
c = 38.28
c ≈ 38.3
By applying cosine rule,
cos(47°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{b}{c}[/tex]
= [tex]\frac{b}{38.3}[/tex]
b = 38.3[cos(47°)]
b = 26.1
Find AC , given that line AD is the perpendicular bisector of BC
Answer:
AC = 29
Step-by-step explanation:
We'll begin by calculating AD. This can be obtained as follow:
AB = 29
BD = 17
AD =?
AB² = BD² + AD²
29² = 17² + AD²
841 = 289 + AD²
Collect like terms
841 – 289 = AD²
552 = AD²
Take the square root of both side
AD = √552
Finally, we shall determine AC. This can be obtained as follow:
DC = BD = 17
AD = √552
AC =.?
AC² = DC² + AD²
AC² = 17² + (√552)²
AC² = 289 + 552
AC² = 841
Take the square root of both side
AC = √841
AC = 29
Xavier left his house at time zero and
drove to the store, which is 18 blocks away,
at a speed of 9 blocks per minute. Then he
stopped and went into the store for 2
minutes. From there, he drove in the same
direction at a speed of 2 blocks per minute
until he got to the bank, which is 6 blocks
away from the store. He stopped at the
bank for 3 minutes. Then he drove home
at a speed of 4 blocks every minute. Make
a graph of showing the number of blocks
away
from home that Xavier is x minutes
after he leaves his house, until he gets back
home.

Answer:
Graph the points, (2,18) (7, 24) and (16, 0)
Step-by-step explanation:
Going to the store takes 2 minutes for 18 blocks, which is the first point
He stays at the store for 2 minutes then takes 3 minutes to get to the bank which is 6 blocks away, add the time together and blocks, and you get the second point
He stopped at the bank for 3 minutes and the drove back home. It takes him 6 minutes to get back home, (24/6), add all the minutes together and you get 16.
(This is assuming the graph is y for blocks and x for minutes)
Read the poem "The Snake" by Emily Dickinson.
A narrow fellow in the grass
Occasionally rides;
You may have met him, — did you not,
His notice sudden is.
The grass divides as with a comb,
A spotted shaft is seen;
And then it closes at your feet
And opens further on.
He likes a boggy acre,
A floor too cool for corn.
Yet when a child, and barefoot,
I more than once, at morn,
Have passed, I thought, a whip-lash
Unbraiding in the sun, —
When, stooping to secure it,
It wrinkled, and was gone.
Several of nature's people
I know, and they know me;
I feel for them a transport
Of cordiality;
But never met this fellow,
Attended or alone,
Without a tighter breathing,
And zero at the bone.
Which statement best describes Dickinson’s use of figurative language in the final stanza?
She uses comparisons to show the speaker’s connection to the snake .
She uses a simile to show that snakes are harmless creatures .
She uses a metaphor to describe the movement of the snake.
She uses exaggeration to emphasize the speaker’s fear of snakes.

A field in the shape of a right triangle is bordered on one side by a stream, on another side by a road, and on a third side by a fence. What angle does this stream make with the road? Enter your answer in the box. Round only your final answer to the nearest degree. ° A field in the shape of a right triangle. The bottom of the field is a fence. The right side of the field is a road. The fence and the road meet at a right angle. The third side of the field is a stream. The distance along the road between the fence and the stream is 20 yards. The distance along the stream between the fence and the road is 27 yards.
Answer:
42°
Step-by-step explanation:
For this problem, it may help you to draw it out to visualize it. You want to find the angle between the stream and road. Based on the description the triangle looks like this.
/ |
Stream(27) / | Road( 20)
/__|
Fence
You know the length of the road is 20, and the stream is 27. The angle can be found by using Cos∅=a/h. Adjacent to where the road and stream meet is the road, 20, and hypotenuse is the stream, 27.
So 20/27 = .74 = Cos∅
To find the angle ∅ use inverse cosine to get 42°.
Hope that helps and let me know if I did anything incorrectly!
You have just used the network planning model for a county road resurfacing project and found the critical path length is 40 days and the standard deviation of the critical path is 10 days. Suppose you want to pick a time (in days) within which you will complete the project with 90% confidence level. What should be that time (in days and round to the nearest whole number)
Answer:
The answer is "53 days"
Step-by-step explanation:
The form for the due date is given below from the above information.
[tex]\text{DUE DATE = Expected Completion Time} + (Z \times \text{Standard Deviation)}[/tex]
The level of confidence relates to the percentage of all samples which can contain a true population variable. It is calculated by a random sampling of the population and is often linked with a certain level of confidence, which would be a probability, usually a percent. The 90% say that the true mean will be 90%, but 10% won't.
The Z-score needs to be measured, measured from percentage points away from the mean in statistics of a value related to the mean (which is to say, the average) of one sequence of items.
[tex]Expected\ time = 40 \\\\Confidence \ interval = 90 = Z-VALUE \ of\ 1.282\\\\Standard \ Deviation= 10\\\\DUE \ DATE = 40 + (1.282 \times 10) = 53 \ days\\\\= 40+ 12.82 =52.82 \approx 53\\\\\therefore[/tex]
The time in days is 53 days.
A aluminum bar 3 feet long weighs 12 pounds. What is the weight of a similar bar that is 3 feet 4 inches long?
Answer:
13 1/3 pounds.
Step-by-step explanation:
3 feet = 36 inches
3 feet 4 inches = 36 + 4 = 40 inches
By proportion the weight of the larger bar = 12 * 40/36
= 12 * 10/9
= 120/9
= 13 1/3 pounds.

Help me wegnerkolmp2741o
Answer:
Step-by-step explanation:
All these amount of money are based on Dan's initial amount, which is x. Ben had 7 more than Dan, so Ben's amount of money is x + 7. Kaden has 4 more than Ben, so Kaden's amount of money is 4 + (x + 7) which is x + 11. So here's the breakdown so far:
Dan: x
Ben: x + 7
Kaden: x + 11
Now it looks like Kaden is the favorite and got another 20 from his mom, so his amount became x + 31. After Dan spends a dollar, making his amount x - 1, Kaden had 9 times what Dan had. Now we have finally:
x + 31 = 9(x - 1) and
x + 31 = 9x - 9 and
40 = 8x so
x = 5.
Dan originally had $5, Ben originally had $12, and Kaden originally had $16

Identify the segments that are parallel, if any, if ∠DCB and ∠CDA are supplementary.
Answer:
C
Step-by-step explanation:
We are given that
[tex]\angle[/tex]DCB and [tex]\angle[/tex]CDA are supplementary.
We have to identify the parallel segments if [tex]\angle[/tex]DCB and [tex]\angle[/tex]CDA are supplementary.
Supplementary angles: If the angles are supplementary then the sum of two angles is 180 degrees.
Therefore,
[tex]\angle DCB+\angle CDA=180^{\circ}[/tex]
Therefore, angle DCB and angle CDA are interior angles .
Because CA is a transversal line and sum of interior angles is 180 degrees.
When the sum of interior angles formed between two lines and on same side of transversal line is 180 degrees. Then the lines are parallel.
Therefore, angle DCB and angle CDA are formed between line AD and BC.
Hence, AD is parallel to BC.
Option C is correct.

Mr Rai sale a watch for Rs 2035 a profit of 10% how much money has he paid to buy the also find his profit amount
Answer:
He paid Rs 1,850 to buy the watch
Profit = Rs 185
Step-by-step explanation:
Cost price = x
Profit = 10% of x
Selling price = Rs 2035
Profit = Selling price - cost price
10% of x = 2035 - x
0.1x = 2035 - x
0.1x + x = 2035
1.1x = 2035
x = 2035 / 1.1
x = 1,850
Cost price = x = Rs 1,850
Profit = 10% of x
= 10% of 1,850
= 0.1 × 1850
= 185
Profit = Rs 185

Maria's luggage travels 36 m in 3 minutes. What is the speed of the conveyer belt in kilometers per hour?
Answer:
0.72 km per hour
Step-by-step explanation:
First, find the speed in meters per hour. Create a proportion where x is this speed:
[tex]\frac{36}{3}[/tex] = [tex]\frac{x}{60}[/tex]
3x = 2160
x = 720
So, the speed is 720 meters per hour. Convert this to kilometers per hour by dividing 720 by 1000, since there are 1000 meters in a kilometer:
720/1000
= 0.72
So, the speed of the conveyer belt is 0.72 km per hour
