Answer 1

Answer:

144

Step-by-step explanation:

-12 * -12 = 144

Answer 2

12² =144

but the question was not 12², but -12²

so the answer is -144

if the exercise was between (), so writen like this (-12)²

then you would need to do the - to the power of 2 as well

Find the volume of the cylinder. Use 3.14 for π. Round your answer to the nearest tenth.

Answers

Answer:

409.77 is the answer!

Step-by-step explanation:

3 x 3 x 3.14 x 14.5

pie x r^2 x h = V

Answer:

The volume of the cylinder is 410 ft^3

Step-by-step explanation:

To find the volume, we must know the formula. The formula is, V = π r^2 h. We already know that the diameter is 6ft, so we have to cut that in half to get the radius. 6/2 = 3. The radius is 3ft. Now we can plug in the values.

V = π*3^2*14.5

V = π*9*14.5

V = 409.977841

V = 410.0

what is the inequality shown

Answers

Answer:

-4 ≤ x ≤ 3

Step-by-step explanation:

Well, we can see that the endpoints land on -4 and 3 and the numbers between -4 and 3 are included. And since the endpoints -4 and 3 have colored dots, they are included as well. Therefore the inequality is -4 ≤ x ≤ 3.

Answer:

-4 ≤ x ≤ 3

Step-by-step explanation:

Because the circles are closed, we know that the inequaily sign will be either "≤" or "≥", meaning that the dotted points are included. Looking at the number line, we can see that the dots lie on points -4 and 3. Because -4 is less than 3, the sign will be a lesser than sign. The line inbetween includes all numbers between -4 and 3.

So, in conclusion, -4 ≤ x ≤ 3 is the inequality shown.

At the end of a baseball game, the players were given the choice of having a bottle of water or a box of juice. Of all of the players, 12 chose a bottle of water, which was 3 4 of the total number of players. Write and solve an equation to determine p. the total number of players at the baseball game. Show your work

Answers

Answer:

p=48

Explenation:

Total number of players = p

According to given scenario:

p - 12 = 3/4p

By simplifying

Taking terms with p on left and constants on right

p - 3/4p = 12

By taking LCM for left side to make denominators same

4/4*p -3/4p = 12

(4p -3p)/4 = 12

1p/4 = 12

Multiplying both sides by 4 we get

p = 12 * 4

p = 48

So total number of players is 48

Oy = 3x + 2
Oy = 3x - 2
help pls my education depends on it

Answers

The answer is y = 3x - 2. To find slope, you subtract y2 - y1 and x2 - x1. In this case, y2 - y1 = 10 - 4 and x2 - x1 = 4 - 2. You would result in 6/2, which can be reduced to 3. Your slope is 3, so the first and second answer automatically are eliminated. Next, you could either draw it out on a coordinate plane or just visualize it. The starting point that goes through each line would be -2, which means D, or y = 3x - 2, is the correct answer.

For triangle xyz , the measures of angles x,y, and Z are known. Which method should be used to start solving triangle xyz?
law of sines
law of cosines
neither law can be used
both laws can be used

Answers

The triangle xyz has three sides and three angles

Neither law can be used to solve the triangle

How to determine the appropriate method?

As a general rule, the law of sines states that:

x/sin(X) = y/sin(Y) = z/sin(Z)

As a general rule, the law of cosines states that:

x^2 = y^2 + z^2 - 2yz cos(X)

From the question, we understand that only the angle measures are given.

The sine and the cosine laws above require at least one side length of the triangle in order to solve the triangle

Since the side lengths are not known, then neither of the laws can be used

Kira’s office has two printers. The printing rate of printer 1 is shown in the table. The printing rate of printer 2 is shown in the graph

Indicate which proportional relationship, and explain how the other printer needs to change to become proportional.

Answers

a) The number of pages prints at t=0 is p0=0.
The number of pages prints at t=4 minutes is P1=64 pages.
The first coordinate of the graph is (a, b)=(0, 0).
The second coordinate of the graph is (c, d)=(10 min, 250 pages). The expression for the rate of the pages printed by the first printer is,

r1 = p1 - p0 / 4-0

Substitute the given values in the above expression.

r1 = 64 pages - 0 / 4 minutes - 0
= 16 pages / min

b) Printer 1 prints at an exponential rate. Both the x and y values increase by a constant ratio of 2. We can either use a logarithm of the first printer or find a constant number of documents it can print / time to become proportional.

Suppose m and n vary inversely and n=17 when m=-4. A) write an equation that models the variation . B) find n when m =-136

Answers

The equation that models the variation is -4 = k/17.

The value of n when m is -136 is 2.

What is inverse proportion?

When two variables vary inversely, as one variable increases, the other variable decreases.

The formula used to represent inverse proportion is:

m = k/n

m = dependent variable n = independent variable k = constant of proportionality

-4 = k/17

k = 17 x -4 = -68

-136 = -68/ n

n = -136 /68

n = 2

Step-by-step explanation:

In geometry, arrows on lines mean that those lines are parallel.

Therefore, as one pair of opposite sides have 1 arrow, and the other pair of opposite sides have 2 arrows, this indicates that each pair of opposite sides are parallel.

Quadrilaterals that have 2 pairs of parallel sides are the rhombus and the parallelogram. A rhombus is a parallelogram that has 4 sides of equal length. As the side lengths of the given shape are equal in length, this quadrilateral is a special type of parallelogram called a rhombus.
