Read this main idea: The sun is the center of our solar system. Choose three details that go with the main idea.
The sun's gravity holds the planets in place. It provides them with heat and light.
The largest stars, called supergiants, are 1,500 times bigger than our sun.
It takes Earth 365 days to orbit the sun. Jupiter takes 12 years!
Our sun is not the largest or hottest star. It is a medium sized yellow star.
Radio telescopes use radio waves to show stars in great detail.
Astronomers long ago and today use star charts to map star locations.
All of the planets in our solar system revolve around one star-our sun.
Stars can be blue, white, yellow, or red. Blue stars are the hottest.
A reflector telescope bounces star light through mirrors.
Answer:
1. All planets in our solar system revolve around one star- our sun
2. The sun's gravity holds the planets in place. It provides them with heat and light.
3. It takes Earth 365 days to orbit the sun. Jupiter takes 12 years!

Find the area of the figure, in square meters, to 1 decimal place. pls hurry n be honest with the answer
Answer:
379.20
Step-by-step explanation:
You have to find the area of the rectangle which is 16 times 8 and that is 128
Then you have to find the area of the left and right semicircles this is 3.14 times 4 squared (because 8 is the diameter 4 is the radius) and this is 50.24
Next you need to find the area of the top and bottom semicircles this is 3.14 times 8 squared (because 16 is the diameter and 8 is the radius) and this is 200.96
then you just add it all up and its 379.20

Monica has a triangular piece of fabric. The height of the triangle is 15 inches and the triangle’s base is 6 inches. Monica says that the area of the fabric is 90 square inches . What error did Monica make? Explain your answer.
Answer:
[tex]let \: area \: be \: a, \: height \: be \: h, \: base \: be \: b \\ a = \frac{1}{2} bh \\ a + \delta \: a = \frac{1}{2} \times (b + \delta \: b)(h + \delta \: h) \\ a + \delta \: a = \frac{1}{2} (bh + b\delta \: h + h\delta \: b + 0) \\ \delta \: a = \frac{1}{2} (b\delta \: h + h\delta \: b) \\ \frac{\delta \: a}{a} = \frac{b\delta \: h + h\delta \: b}{bh} \\ \frac{\delta \: a}{a} = | \frac{\delta \: h}{h} | + | \frac{\delta \: b}{b} | \\ \frac{\delta \: a}{ 90} = \frac{0.5}{15} + \frac{0.5}{6} \\ \delta \: a = 10.5 \: {cm}^{2} [/tex]

The area of the triangle is 45 square inches.
What is a triangle?'A triangle is a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees.'
Here, we have,
According to the given problem,
Area of the triangle = (1/2) × 6 × 15
= 45 squared inches
Monica, when calculating the area of the triangle, missed out on multiplying 0.5 to the product of base and height.
Hence, we can conclude, the correct area of the triangle is 45 squared inches.

Drag justifications into the table to explain each step in solving the equation 5(2x+1)=2(4x-7)+3
The justifications are in the order distributive property, associative property of addition, Combine like terms, Addition property of equality and multiply by LCD.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given equation is,
5(2x + 1) = 2 (4x - 7) + 3
Using distributive property, a(b + c) = ab + ac
10x + 5 = 8x - 14 + 3
10x + 5 = 8x - 11 [associative property of addition]
10x - 8x + 5 = -11
2x + 5 = -11 [Combine like terms]
2x + 5 - 5 = -11 - 5
2x = -16 [ Addition property of equality]
2x / 2 = -16/2
x = -8 [multiply by LCD]
Hence the justifications are done.

given that,
The largest living thing on earth is a California sequoia tree named the “General Sherman”. The diameter of the tree at the base is 36 feet.
now, we have to find the approximate circumference of the trunk .
we have,
The diameter of the tree at the base is 36 feet.
so, radius = 36/2 = 18 ft
we know that,
circumference of the trunk = 2πr
here, r = 18
so, we get,
circumference of the trunk is:
=2 * 3.14 * 18
=113 ft
Hence, the approximate circumference of the trunk is 113 ft.

Step-by-step explanation:
First find the area of the whole circle.
A=pi(r^2)
A=pi((18+4)^2)
A=pi(484)
Next find the area of the none shaded circle.
A=pi(r^2)
A=pi(18^2)=pi(324)
Then subtract to get pi(160)
