Answer:
x = 15°
Step-by-step explanation:
The secant- tangent angle x is half the difference of the intercepted arcs, that is
x = [tex]\frac{1}{2}[/tex] (80 - 50)° = 0.5 × 30° = 15°

The function V=25000\left(0.82\right)^tV=25000(0.82) t models the depreciation of the value of a new car that originally cost $\text{25,000}25,000. VV represents the value of the car and tt represents the time in years from the time the car was purchased. What is the value of the car after 6 years?
Answers
Answer:
V = 7,600.17
Step-by-step explanation:
Given:
V=25000(0.82)^t
Where,
V = value of the car
t = time in years
Find V when t = 6
V = 25,000(0.82)^t
= 25,000(0.82)^6
= 25,000(0.304006671424)
= 7,600.1667856
Approximately
V = 7,600.17

Answer:
Curved Surface Area = 48π cm² (≈ 150.72 cm²)
Total Surface Area = 120π cm² (≈ 376.8 cm²)
Step-by-step explanation:
GIVEN :-
Height of cylinder = 4 cmBase radius = 6 cmTO FIND :-
Area of cylinderGENERAL FORMULAES TO BE USED IN THIS QUESTION :-
Curved Surface Area of cylinder = 2πrh
Total surface Area of cylinder = 2πrh + 2πr² = 2πr(h + r)
SOLUTION :-
Curved Surface Area of cylinder = 2×π×6×4 = 48π cm² ≈ 150.72 cm²
Total Surface Area of cylinder = 2×π×6(4 + 6) = 120π cm² ≈ 376.8 cm²

Mara drew this net to find the surface area of a triangular prism. Which is the surface area of the triangular prism?
A.312
B.402
C.372
D.492
(Square cm)
Answers
Answer:
C.372
Step-by-step explanation:
A prism is a three dimensional shape with two identical shapes facing each other known as bases.
A triangular prism has two triangular bases and three rectangle.
From the net attached:
Area of triangle 1 = area of triangle 2 = (1/2) * base * height = (1/2) * 10 cm * 12 cm = 60 cm²
Area of rectangle 1 = Area of rectangle 2 = length * width = 13 cm * 7 cm = 91 cm²
Area of rectangle 3 = base * height = 10 cm * 7 cm = 70 cm²
Total surface area = Area of triangle 1 + Area of triangle 2 + Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3
Total surface area = 60 + 60 + 91 + 91 + 70 = 372 cm²

What is the total payment
required to pay off a promissory
note issued for $500.00 at 10%
ordinary interest and a 180-day
term?
Answers
Answer:
the total payment need to pay is $525
Step-by-step explanation:
Given that
The amount at promissory note issued is $500
The rate of interest is 10%
And, the time period is 180 days
So, the total payment included is
= $500 + ($500 × 10% × 180 days ÷ 360 days)
= $500 + $25
= $525
hence, the total payment need to pay is $525

Side in EFGH = 3/4(Side in ABCD) = 3/4(16m + 24) = 12m + 18
Perimeter of ABCD = 4(16m + 24) = 64m + 96
Perimeter of EFGH = 4(12m + 18) = 48m + 72
Difference of perimeters = 64m + 96 - 48m - 72 = (16m + 24) units

what’s the volume ??

Answers
Question:
What’s the volume ?
Answer:
Volume: 8663.2
Area : 392
Step-by-step explanation:
The formula for volume is length times width times height (L x W x H)
So
28 x 28 = 784 x 22.1 = 17326.4 (Crazy right) But this is not the answer. A triangle is half of a Square so we divde by 2
17326.4 / 2 = 8663.2
The Volume is 8663.2
And if you are looking for the Area it's 392
