An angle measures 16° more than the measure of its supplementary angle. What is the measure of each angle?

1 answer:

3 0

82 degrees and 98 degrees

First, find the original equation

180 = (x) + (x + 16)

Simplify: 180 = 2x + 16

Next, use the subtraction property of equality to subtract 16 from both sides

180 - 16 = 2x + 16 - 16

Simplify: 164 = 2x

Then, you can use the division property of equality to find the value of x

164/2 = 2x/2

Simplify: 82 = x

Now, we know that the first angle equals 82 degrees and that the second angle equals 98 degrees

What is the sum of the integers between the square root of 12 and 40?

satela [25.4K]

1.

the closest perfect squares of 12 are 9 and 16,

that is 9<12<16

so
$\sqrt{9}\ \textless \ \sqrt{12}\ \textless \ \sqrt{16}$

$3\ \textless \ \sqrt{12}\ \textless 4$

this means, $\sqrt{12}$ is 3 point something...

2.

similarly

36<40<49

so

$\sqrt{36}\ \textless \ \sqrt{40}\ \textless \ \sqrt{49}$

$6\ \textless \ \sqrt{40}\ \textless \ 7$

which means $\sqrt{40}$ is 6 point something...

3.

<span>the sum of the integers between the square root of 12 and 40 is the sum of 4, 5 and 6, since 4 is the smallest integer after root 12, and 6 the greatest integer to before root of 40.

Answer: 15</span>

Let First Sphere be the Original Sphere

its Radius be : r

We know that Surface Area of the Sphere is : 4π × (radius)²

⇒ Surface Area of the Original Sphere = 4πr²

Given : The Radius of Original Sphere is Doubled

Let the Sphere whose Radius is Doubled be New Sphere

⇒ Surface of the New Sphere = 4π × (2r)² = 4π × 4 × r²

But we know that : 4πr² is the Surface Area of Original Sphere

⇒ Surface of the New Sphere = 4 × Original Sphere

⇒ If the Radius the Sphere is Doubled, the Surface Area would be enlarged by factor : 4

Explain why x=4 is not in the domain of the function f(x)=√x-5 ?

lianna [129]

Since we are dealing with a radical then x - 5 ≥ 0, for real values

x = 4 is less than 5 , hence is not in the domain

A soccer field has a length of 100 yards and a width of 60 yards. Which equation can you use to find the area of the soccer fiel

snow_tiger [21]

Answer:

60 x 100

Step-by-step explanation:

Since the formula for area of a rectangle is length × width, multiplying the sides will get you the area.
