For triangle: bh/2 = (10 * 10)/2 = 50
Add them together: 12.5pi + 50
12.5pi = 39.25
39.25 + 50 = 89.25
It’s closest to D

Answer:
a=2
Step-by-step explanation:
Let's solve your equation step-by-step.
2(a+1)=6
Step 1: Simplify both sides of the equation.
2(a+1)=6
(2)(a)+(2)(1)=6(Distribute)
2a+2=6
Step 2: Subtract 2 from both sides.
2a+2−2=6−2
2a=4
Step 3: Divide both sides by 2.
2a /2 = 4 /2
a=2
A navy cruiser detects a nuclear submarine that is 2500 feet from the cruiser. The angle between the water level and the submarine is 15.5 degrees. How deep is the submarine?
Answers
Answer:
Depth of the submarine = 668.09 feet
Step-by-step explanation:
From the figure attached,
In triangle ABC,
Distance between a navy cruiser and a nuclear submarine = 2500 feet
Angle between the water level and the submarine = 15.5°
By applying sine rule in the given triangle,
sin(∠BAC)° = [tex]\frac{BC}{AC}[/tex]
sin(15.5°) = [tex]\frac{BC}{2500}[/tex]
BC = 2500[sin(15.5)]
BC = 668.09 feet
Therefore, submarine is 668.09 feet deep in the sea.
The bottom of a cylinder has a circumference of about 60 in. What is the approximate diameter of the cylinder? Round to the nearest tenth. Use 3.14 for π . Enter your answer in the box.
Answers
Answer:
19.1 inches
Step-by-step explanation:
Circumference divide by diameter = 3.14 (C/d = 3.14)
60/d = 3.14
multiply both sides of the equation by d
60 = 3.14d
divide both sides by 3.14
d = 60/3.14
d = 19.108
d = 19.1

Jalen bought 9/16 pound of blue cheese at the deli. He also bought 1 3/16 pounds of Swiss cheese. He estimates that the he bought about 1 3/4 pounds of cheese altogether. Which best describes Jalen's estimate?
A. It is not reasonable because 9/16 is about 3/4 and 1 3/16 is about 1 1/2, and 3/4 + 1 1/2 = 2 1/4.
B. It is reasonable because 9/16 is about 1/2 and 1 3/16 is about 1 1/4, and 1/2 + 1 1/4=1 3/4.
C. It is not reasonable because 9/16 is about 1 and 1 3/16 is about 1, and 1 + 1 = 2.
D. It is reasonable because 9/12 is about 1 and 1 3/16 is about 1, and 1 + 1 = 2/2, which is about 1 3/4.

Planes that fly at high speeds and low elevations have radar systems that can determine the range of an obstacle and the angle of elevation to the top of the obstacle. The radar of a plane flying at an altitude of 20,000 feet detects a tower that is 25,000 feet away, with an angle of elevation of 1∘.
a. How many feet must the plane rise to pass over the tower?
The plane must rise at least _____feet to pass over the tower.
Question 2
b. Planes cannot come closer than 1000 feet vertically to any object. At what altitude must the plane fly in order to pass over the tower?
The plane must fly at an altitude of at least ____ feet to pass over the tower.
Answers
Answer:
a. About 436 ft
b. 21,436 feet
Step-by-step explanation:
a. Notice how the plane's rise (h), its horizontal distance from the tower, and its distance to the top of the tower (25,000 ft) all form a right triangle. If we want to find h, we need some way of putting it in an equation with the two quantities we already know: the angle of elevation and the distance to the top.
In the language of right triangles, we want to combine an angle, the side opposite the angle, and the hypotenuse. The sine function is perfect for this, since [tex]\sin{\theta}=opp/hyp[/tex]. For our problem, opp = h, hyp = 25,000, and θ = 1°, so our equation becomes
[tex]\sin{1^\circ}=h/25000[/tex]
or equivalently
[tex]h=25000\sin{1^\circ}\approx436[/tex] ft (rounded up to the nearest whole foot)
b. If the plane is currently flying at 20,000 feet, it needs to rise about 436 feet to clear the top of the tower, and another 1,000 feet to follow safety protocol, making its required altitude 20,000 + 1,000 + 436 = 21,436 feet.

[Help asap, will mark brainliest] In the figure, line a is parallel to line b.
Answers
Answer:
m <5 = 65°
m<8 = 115°
Step-by-step explanation:
m<2= m<5 = 65° (vertically opposite angles are equal)
m<5 + m<4 = 180 (co-int angles, parallel lines)
65+ m<4 =180
m<4 = 115°
Therefore
m<4=m<8 = 115° (vertically opposite angles are equal)
Answer:
m<5 = 65 degrees m<8 = 115 degrees
Step-by-step explanation:
m<2 = 65 degrees
m<2 = m<5 so
m<5 = 65 degrees
A line is 180 degrees, so
180 degrees - 65 degrees = 115 degrees
m<8 = 115 degrees
