A triangle is given and a line is drawn from the vertex on the opposite side such that 2 triangles are formed. 1st triangle has 2 equal sides and vertex angle as 64 degrees and 2nd triangle has 2 equal sides and vertex angle as x degrees is given.
Answers
Answer:
116 degrees
Explanation:
If we divide the triangle from the vertex of the triangle, the vertex angle of each triangle would lie on a straight line in the triangle. Angle on a straight line is 180 degrees.
If the vertex angle of one triangle is 64 degrees then the vertex angle x of the other triangle is 180 degrees - 64 degrees = 116 degrees.

Answers
Answer:
Y = 0.0315x + 9.4764
Residual = 2.35
Correlation Coefficient = 0.847
Step-by-step explanation:
From the R output given :
Intercept = 9.4764
Slope = 0.0315
x = number of manufacturing enterprise employing 20 or more workers
y = annual mean concentration of Sulphur dioxide
The regression equation :
y = bx + c
b = slope ; c = intercept
y = 0.0315x + 9.4764
Prediction using the regression equation :
The predicted y value, when x = 250
y = 0.0315(250) + 9.4764
y = 17.3514
The residual, if actual annual concentration = 15
Y residual = 17.35 - 15 = 2.35
The correlation Coefficient value, R
R = √R²
R = √0.717
R = 0.847

Answer:
It takes _8_ s for an object to fall 1000 feet. In 10 s, an object will fall _1600_ feet.
Step-by-step explanation:
A. Determination of the time it takes for the object to 1000 ft.
Distance (d) = 1000 ft
Time (t) =?
t = √(d/16)
t = √(1000/16)
t = 8 s
B. Determination of how much feet an object will fall in 10 s.
Time (t) = 10 s
Distance (d) =?
t = √(d/16)
10 = √(d/16)
Take the square of both side
10² = d/16
100 = d/16
Cross multiply
d = 100 × 16
d = 1600 ft
SUMMARY
It takes _8_ s for an object to fall 1000 feet. In 10 s, an object will fall _1600_ feet.

Answer:
B. The solution is valid because all steps to solve the inequality for F are correct.
Step-by-step explanation:
F - 32 ≤ 0
Add 32 to both sides of the equation to have;
F -32 + 32 ≤ 0 + 32
F ≤ 0 + 32
F ≤ 32
It can be observed that to solve for F, the steps are correct. Thus the solution is valid. Therefore, the correct choice in the given question is the solution is valid because all steps to solve the inequality for F are correct.

Mandy borrows $10,000 for 3 years at a 6% interest. What is the cost of the loan, or total interest?
Answers
Answer:
Interest Earned ₹ 1,800
Principal Amount ₹ 10,000
Total Value ₹ 11,800
The cost of the loan for Mandy will be $11800 and the total interest for 3 years will be $1800.
What is simple interest?Simple interest is a predetermined proportion of the principal amount borrowed or lent that is paid or received over a set period of time.
Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.
In another word, if the principle amount is the same in each time period then the interest will also same for every time period.
Given that
Principle amount = $ 10000
Time period = 3 years
Rate of interest = 6%
Rate of interest at the end of 1st year
10000 × 6/100 ⇒ $600
Since in simple interest rate of interest remain same so
Rate of interest for 3 years
3 × 600 = $ 1800 hence rate of interest will be $1800.
Cost of the loan = principle amount + total interest
Cost of the loan = 10000 + 1800 ⇒ $11800 will be the cost of the loan.

George bought a cylindrical tank for his garden but he forgot to ask the seller what the diameter of the tank was. He needs to know the diameter of the tank so that he can build a platform for it to sit in. The seller told him the volume and the height, calculate the diameter of the tank using the information below
“ the volume of the tank is 300 π ft^2 and its height is 10ft
Answers
Answer:
[tex]d = 2\sqrt{30}[/tex]
Step-by-step explanation:
Given
[tex]Volume = 300\pi ft^3[/tex]
[tex]Height =10ft[/tex]
Required
The diameter
The volume of a cylinder is:
[tex]V = \pi r^2h[/tex]
So, we have:
[tex]300\pi = \pi * r^2*10[/tex]
Divide both sides by the common factors
[tex]30 = r^2[/tex]
Take square roots of both sides
[tex]r = \sqrt{30}[/tex]
The diameter is:
[tex]d=2r[/tex]
So:
[tex]d = 2* \sqrt{30}[/tex]
[tex]d = 2\sqrt{30}[/tex]
or
[tex]d = 10.95[/tex]

Sam Store orders 200 pens that list for $0.5 each, 150 pads that list for $0.7 each, and 100
pencils that list for $0.2 each. The single trade discount rate for the order is 15%. Find the net
price of the order and the amount of discount.
Answers
Answer:
Net price = $191.25
Discount Price = $33.75
Step-by-step explanation:
Cost of one pen = $0.50
Cost of 200 pen = 200 × 0.50 = $100
Cost of one pad =$0.70
Cost of 150 pads = 150 × 0.70 = $105
Cost of one pencil = $0.20
Cost of 100 pencils = $20
Total cost of the order = 100 + 105 + 20 = $225
Discount % = 15% of 225
Discount price = ( 15% × 225) = $33.75
Total amount after discount = 225 - 33.75 = $191.25
