[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

Answers
Answer:
The answer is "choice C"
Step-by-step explanation:
Please find the complete question in the attached file.
This is because the temperature in grades Celsius, y, of material could be represented by the previous diagram, in which x is the period, in hours.
It is evident from the study that, the y-intercept is 40 degrees Celsius and thus the temperature difference is 40.
That edge of the top paraboloid is (15-200) so at most -200 ° C at 15 hours the temperature of the material. During 30 hours, the material returns to its initial temperature as the temperature at x = 30 is 40 °C.

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

What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
In 2000, 36 children attended a summer day camp. Attendance has increased by 12% per year since then.
Hence, Number of campers attended summer day camp in 2006 is,
⇒ 36 (1 + 12%)⁶
⇒ 36 (1+ 0.12)⁶
⇒ 36 (1.12)⁶
⇒ 36 × 1.97
⇒ 71
Thus, Number of campers attended summer day camp in 2006 is, 71

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.

Answer: x^2+29x+39
You would first have to set up an equation, which would be ((2x+9)⋅(x+6))-((x-5)⋅(x-3)) to find the area of both rectangles.
Then you can simplify it, which gives us 2x^2+21x+54-(x^2-8x+15)
Then simplify it even more which gives us 2x^2+21x+54-x^2+8x-15
Then we can get our answer: x^2+29x+39

Answers

Answer:
155.52 m³
Step-by-step explanation:
The volume will be the product of the end area and the length of the greenhouse.
The end area consists of 4 triangles and 6 rectangles. We can do a little manipulation of the shapes to simplify the area calculation a bit.
We can divide half of the greenhouse face along its vertical lines to make two trapezoids. Their "bases" will be the lengths of the vertical lines, and their heights will be the dimensions 1.8 m and 0.6 m. Since there are two of each, we can find the end area to be ...
A = 2(1/2)(b1 +b2)(h1) +2(1/2)(b2 +b3)(h2)
A = (3.3 +2.7)(1.8) +(2.7 +0.9)(0.6) = 10.8 +2.16 = 12.96 . . . square meters
__
The volume is then ...
V = Bh
V = (12.96 m²)(12 m) = 155.52 m³ . . . . greenhouse volume
