Find the length of the base of the following pyramid, given the height of the pyramid is 71 meters and the angle of elevation of the base of the pyramid is 42°. Round to the nearest whole number.
127 meters
158 meters
191 meters
212 meters
Answers
base = height / tan(42°)
base = 71/tan(42°)
base = 78.85 m
Now length of the base pyramid = 2× length of the base of the right triangle
= 2 ×78.85
= 157.7 ≈ 158 m
Option B
The length of the base of the following pyramid when the height, angle of elevation is given so it is 158 meters.
Calculation of the length of the base:Since
The height of the pyramid is 71 meters and the angle of elevation of the base of the pyramid is 42°.
So,
[tex]tan (42) = height \div base\\\\base = height \div tan (42)\\\\base = 71\div tan\ (42)\\\\[/tex]
base = 78.85 m
Now
length of the base pyramid = 2× length of the base of the right triangle
= 2 ×78.85
= 157.7
≈ 158 m
Hence, The length of the base of the following pyramid when the height, angle of elevation is given so it is 158 meters.

Kevin earns $12.00 for every 5 story problems he writes. How much would Kevin get for writing 12 problems?
Answers
Answer: $28.80
Step-by-step explanation:
We can start by finding the unit rate. How much money does Kevin earn from writing 1 story problem?
We can find how much Kevin earns from writing 1 story by dividing 12 by 5.
12 ÷ 5 = 2.4.
Therefore, Kevin earns $2.40 for every story he writes.
Now we have to find how much Kevin earns from writing 12 story problems. If Kevin earns $2.40 for every story he writes, then we should mutliply that by 12 to find how much money Kevin earns for writing 12 problems.
2.40 x 12 = 28.8.
In conclusion, Kevin earns $28.80 dollars for writing 12 problems.
Find sin D and sin E. Write each answer as a fraction and as a decimal. Round to four decimals places.
Answers
Answer/Step-by-step explanation:
✔️Sin D = opp/hyp
Opp = 12
Hyp = 15
Sin D = 12/15 = 4/5 (as fraction )
Sin D = 0.8 (as decimal)
✔️Sin E = opp/hyp
Opp = 9
Hyp = 15
Sin E = 9/15 = 3/5 (as fraction)
Sin E = 0.6 (as decimal)
Find the median of these numbers:4,2,7,4,3 *
Answers
Answer:
4
Step-by-step explanation:
median: the middle value. to find this, arrange your numbers in order from least to greatest and find the one in the middle. if there are two in the middle, add them and then divide by 2.
4, 2, 7, 4, 3 → 2, 3, 4, 4, 7
since 4 is in the middle, that is your answer
The median of the sequence is 4.
What is the median?One of the three methods of measuring central tendency is the median. The centre point of a data set is indicated while describing it. The measure of central tendency is this. The mean, median, and mode are the three most popular methods for calculating central tendency.
Given the sequence 4,2,7,4,3,
to find median arrange the values in ascending order,
2, 3, 4, 4, 7
since the sequence has 5 digits so the median is the middle term,
center digit is 4,
median is 4.
Hence the median is 4

y = 2(x - 8)(x+2)
A. What are the X intercept(s)?
B. What is the Vertext?
C. What is the axis of symmetry?
D. What is the Y intercept?
Answers
Answer:
Step-by-step explanation:
y=2(x-8)(x+2)
The x intercepts occur when y=0, so when x=8 and -2
The vertex is where the equation is at a minimum/maximum in this case (x,y)=(3,-50)
The axis of symmetry occurs between the two roots, 8 and -2 which x=3
The y intercept is the value of y when x=0, in this case (0, -32)

Can anyone help me with this?
Answers
Answer:
528 in.²
Step-by-step explanation:
Surface area of the figure = (surface area of the smaller rectangular prism + surface area of the bigger prism) - area of 1 of the base of the smaller rectangular prism
✔️Surface area of the bigger rectangular prism = 2(WL + HL + HW)
= 2(10*12 + 5*12 + 5*10) = 2(120 + 60 + 50)
= 2(230)
Surface area of bigger rectangular prism = 460 in.²
✔️Surface area of the smaller rectangular prism = 2(WL + HL + HW)
= 2(2*2 + 8*2 + 8*2) = 2(4 + 16 + 16)
= 2(36)
Surface area of smaller rectangular prism = 72 in.²
✔️area of 1 of the base of the smaller rectangular prism = L*W = 2*2 = 4 in.²
✅Surface area of the figure = (460 + 72) - 4
= 532 - 4
= 528 in.²

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of units of orange juice at beginning = 30 units
The number of units purchased = 50 units
Total units = 30 + 50 = 80 units
The number of units at the end = 30 units.
The number of units sold.
= Total units - Units at the end
= 80 - 30
= 50 units.
