URGENT 30 POINTS An engineer needs to find the length of a beam to support the beam holding the wall. If the two beams are perpendicular to one another, and a=4 m and b=1 m, find z. Give your answer to one decimal place.
Answers
The value of z in the given arrangement is 2 m.
What are similar triangles?Similar triangles are the triangles that look similar to each other, but their sizes might not be exactly the same.
Also,
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.
Given that, an engineer needs to find the length of a beam to support the beam holding the wall, the two beams are perpendicular to one another, and a=4 m and b=1 m, we need to find z.
So, here we will use the concept of similar triangles,
According to the definition the corresponding sides are in proportion.
So, we get,
z/a = b/z
z² = 4
z = 2
Hence, the value of z in the given arrangement is 2 m.

A teacher is making worksheets for the next unit. He can create 3 worksheets in an hour and has 10 worksheets already created from the previous year. Which of the following lengths of time worked will not be long enough for the teacher to have created 27 worksheets. * Check All That Are True*
6 hours, 10 hours, 8 hours, 2 hours, 4 hours
Answers
Answer:
2 hours, 4 hours
Step-by-step explanation:
So lets go over what we know.
There are already 10 worksheets created.
Every 1 hour 3 more are made.
27 worksheets need to be made.
Ok, the first thing we can do is subtract the amount of worksheets needed by the amount we laready have:
27-10
=
17
Now, lets divide the amount of worksheets we still need, by how many we make each hour:
17/3
=
Well, 3 goes into 15, 5 times. Then 2 is left. So we know it takes 5 2/3 hours to create all 27 worksheets.
Looking at the answers, 6 hours, 8 hours, and 10 hours would work. However 2 hours and 4 hours would not work.
Hope this helps! ;)

Answers
Answer:
∠Q ≈ 42.969, ∠P ≈ 52.03, QR ≈ 15.036
Step-by-step explanation:
Law of sines:
13/sin Q = 19/sin 85°
=> sin Q = 13 × sin 85°/19
=> Q = sin^-1 (13 × sin 85°/19)
=> Q ≈ 42.969
∠P=> 180 - 85 - 42.969 ≈ 52.03
QR/sin 52.03° = 19/sin 85°
=> QR = sin 52.03° × 19/sin 85°
=> QR ≈ 15.036

Step-by-step explanation:
The two semicircles add to a full circle.
For the circle, d = 18 cm.

Jane has saved 600 dollars in a college fund. She added money to the account over the next year and at the end of the year, the account had 890 dollars.
!! Write an equation to represent the amount she saved over the year. !!
Answers
explanation:
Answer:
S=End amount-Starting amount
Or(with values)
290=890-600
Step-by-step explanation:
So lets get together all our variables.
First, lets create a variable that shows the amount of money saved over the year.
Lets use S, for savings.
Next, lets take our end value, which was 890, and subtract it from our orgninal value.
This will get you the amount of money that Jane earned over the year. This will look like:
890-600
Or
End value=orginal value.
Now S will be equal to the amount of money Jane earned.
So we can write this as:
S=890-600
Or
Amount of money earned=end value-orginal value
Hope this helps!

Answer:
45
Step-by-step explanation:
You can use the degrees to find the answer. A right triangle always adds up to 180 degrees. The right angle is 90 degrees.
X + Angle A + Angle B = 180 degrees.
Substitute.
X + 90 degrees + 45 degrees = 180 degrees.
Add them up.
x + 135 degrees = 180 degrees.
now subtract 135 from both sides.
x = 45
