11. 5 and 1/3 cubic cm

Step-by-step explanation:

4 · 4 · 2 = 32

32 times 1/2 = 16

Answer 2

Answer:

10: The volume is 2[tex]cm^{3}[/tex]

11: The volume is [tex]\frac{8}{27}[/tex][tex]cm^{3}[/tex]

Step-by-step explanation:

Question 10: ([tex]\frac{1}{2}[/tex] * 4)([tex]\frac{1}{2}[/tex] * 2)([tex]\frac{1}{2}[/tex] * 2) = 2 * 1 * 1 = 2[tex]cm^{3}[/tex]

Question 11: ([tex]\frac{1}{3}[/tex] * 4)([tex]\frac{1}{3}[/tex] * 2)([tex]\frac{1}{3}[/tex] * 1) = [tex]\frac{4}{3}[/tex] * [tex]\frac{2}{3}[/tex] * [tex]\frac{1}{3}[/tex] = [tex]\frac{8}{27}[/tex][tex]cm^{3}[/tex]

Calculating the measure of the angle A

From the question, we have the following parameters that can be used in our computation:

m∠A = 110 degrees

The above implies that the measure of the angle A is 110 degrees

Since there are no other information, we can conclude that

The measure of the angle A is 110 degrees

The picture below shows a pole and its shadow:

A pole is shown with a right triangle side. The right triangle has hypotenuse 365 cm and base 27 cm.
What is the height of the pole? (1 point)

Select one:
a. 196 centimeters
b. 244 centimeters
c. 338 centimeters
d. 364 centimeters

Answers

Answer: 220cm

Step-by-step explanation:

Let's make the base of this triangle 'a' which we know is 21cm

While 'a' and 'b' in Pythagorean are interchangeable, 'c' will ALWAYS be the hypotenuse.

That being said, we also know that 'c' is 221cm

Once we plug in the numbers we have been given, our formula looks like this: 21 squared + b squared = 221 squared

Now it's time to square 'a' and 'c'

Our equation is now simplified to: 441 + b squared = 48841

Now, we need to isolate 'b squared' to find it's value. We do this by subtracting 441 from both sides (it needs to be from both sides to keep the equation even)

With 441 subtracted from both sides, our equation is now: b squared = 48400

Our last step is to find the square root of both sides of the equation, because 'b' is the value of the height of the triangle, but right now we have 'b squared' so to turn that into 'b' we have to find the square root of 'b squared', which would give us 'b' (square roots and squares cancel each other out).

We know that whatever we do to one side must also be done to the other, so since we just found the square root of 'b squared', now we need to find the square root of 48400, which is 220.

That would make our equation: b = 220

b = height = 220

Answer:

D.) 364 centimeters

Step-by-step explanation:

365 Δ 27

364

27 + 364 = 391

(you have to add the smaller numbers together so that they are bigger than the hypotenuse.)

What is the equation of a line?

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

Function 1:

With coordinates (0, -2) and (2, 0)

Now, m=(0+2)/(2-0)

m=1

Substitute m=1 and (x, y)=(0, -2) in y=mx+c, we get

-2=c

Substitute m=1 and c=-2 in y=mx+c, we get

y=x-2

Function 2:

With coordinates (-2, 0) and (0, 4)

Here, m=(4-0)/(0+2)

m=2

Substitute m=2 and (x, y)=(-2, 0) in y=mx+c, we get

0=-4+c

c=4

Substitute m=2 and c=4 in y=mx+c, we get

y=2x+4

Therefore, options B and D are the correct answers.

HELP WILL GRIVE BRAIN 100 POINTS PLEASE ANSWER ALL 5

Answers

Answer:

1. The sum of 4 and x is 7, and to isolate the variable, you move the 4 to the other side and the equation will change into x=7-4, giving us x = 3

2. To solve this inequality, you must isolate the variable x by moving -9 to the other side. To do this, you have to divide 27 by -9, and this causes the direction of the inequality sign to change. After you divide, the inequality changes to this: x<-3

3. since there are no negative numbers involved in this inequality, you divide 3 by 1/4 (or multiply it by 4) to isolate x. this gives us x <= -12

4. To solve this algebraic equation, you must isolate the variable 3x. To do this, you must move -9 to the other side of the equation by adding 9 to the 6. this gives us 3x=15 and x = 5

5. To put x by itself, you subtract 1 by 4, giving you x<-3
