Step-by-step explanation:

The given angle is 107°;

Since the lines given are parallel and a transversal cuts them, angle 1 and 107° are corresponding angles.

Corresponding angles are equal;

So, ∠1 = 107°;

Now, ∠1 and ∠2 are angles on a straight line;

∠1 + ∠2 = 180°

107° + ∠2 = 180°

∠2 = 180° - 107° = 73°

Find the volume of a cylinder with base radius of 3 and height of 2

Lunna [17]

Answer:

Volume equals 56.6 when rounded to the nearest tenth

Step-by-step explanation:

YOU NEED A CALCULATOR TO SOLVE THIS!

To find the volume of a cylinder you need the formula $V = \pi r^{2}h$

Now that you have the formula you plug in the radius and the height

$V = \pi (3^{2}) (2)$

Then solve

$V = \pi (9)(2)$

$V = 18\pi$

$V = 56.548667764616278$

What is the domain of the function represented by the graph?

dezoksy [38]

Answer: Choice C. $x \ge -3$

============================================

Explanation:

The domain is the set of all allowed x inputs.

Here we see that x = -3 is the smallest x value possible as it is from the left-most point. The graph goes on forever to the right, so there is no largest x value. Effectively infinity is the largest x value even though infinity is not a number.

We can say the domain is $-3 \le x < \infty$ which can be simplified to $-3 \le x$ or $x \ge -3$

In short: x can be -3 or larger.

How can knowing 4 times 7 help find the product of 8 times 7.

Nadya [2.5K]

Because 4x2 = 8, so 4x7=28, then you times 28 by 2 which equals 56 and 8x7=56

HELPPPP What is the volume of the square pyramid? Use Pythagorean’s Theorem to find the height of the pyramid

aalyn [17]

Answer: 4,111.7 mm³

Step-by-step explanation:

You need to use this formula to calculate the volume of the square pyramid:

$V=\frac{s^2h}{3}$

Where "s" is the lenght of any side of the square base and "h" is the height of the pyramid.

Find the height with the Pythagorean Theorem:

$a^2=b^2+c^2$

Where "a" is the hypotenuse and "b" and "c" are the legs of the right triangle. Let be "c" the height of the pyramid.

You can identify in the figure that:

$a=26mm\\\\b=\frac{23mm}{2}=11.5mm\\\\c=h$

Then, you can find the height:

$(26mm)^2=(11.5mm)^2+h^2\\\\h=\sqrt{(26mm)^2-(11.5mm)^2}\\\\h=23.318mm$

Then, knowing that:

$s=23mm\\h=23.318mm$

You can calculate the volume:

$V=\frac{(23mm)^2(23.318mm)}{3}=4,111.7mm^3$

Please help me (30 points) 1. A recipe calls for 2 1/3 cups of flour, 3/4 cups of white sugar, and 1/3 cups of brown sugar. The

Katena32 [7]

Lets find how much flour we need for just one serving.

2 2/3 ÷ 6

8/3 ÷ 6

8/3 * 1/6

8/18

4/9 cup of flour per serving

If we triple the recipe (6 * 3 = 18), we will have a total of 18 servings. Multiply the amount of flour we got for one serving to 18 servings.

4/9 * 18/1

72/9

8 cups of flour for 18 servings

Best of Luck!
