Each cube in the prism is one cubic unit.

What is the volume of this rectangular prism?

Answers

Answer:

90 units, the reason for this is because the front of the cub has 30 units, and the side of the cube has three row, so you multiply 30 by 3 to get 90

Width is 6 height is 5 and length is 3 so 6x5x3=90 so it’s 90 units cubed

Then, reflect across the x-axis.

Answers

this  would be a reflection

Step-by-step explanation:

I know this because reflections are like this

1) over the x axis- change the y

2) over y axis - change sign on x

3) flip over a line of reflection

The given transformations are rigid transformation in which the image

can be located by a formula.

Response:

First reflect across the x-axis then reflect across the y-axis

Figure: Second graph

First, rotate 180° counterclockwise around the origin. Then reflect across the x-axis.

Figure: Third graph

First translate 9 units to the left. Then reflect across the x-axis

Figure: First graph

Which method is used to determine the transformation of an image?

The coordinates of (x, y) following a reflection across the x-axis is (x, -y)

The coordinates following a reflection across the y-axis is (-x, y)

The points of the triangle following the first transformation is therefore;

(4, 4) → (4, -4) → (-4, -4)

(8, 4) → (8, -4) → (-8, -4)

(6, 6) → (6, -6) → (-6, -6)

The image from the first transformation is (-4, -4), (-8, -4), (-6, -6), which

corresponds to the second graph.

The coordinates following a rotation of (x, y) by 180° about the origin is (-x, -y)

A reflection of the point (-x, -y) about the x-axis is (-x, y).

Therefore;

(4, 4) → (-4, -4) → (-4, 4)

(8, 4) → (-8, -4) → (-8, 4)

(6, 6) → (-6, -6) → (-6, 6)

The image from the second transformation is (-4, 4), (-8, 4), (-6, 6), which corresponds to the third graph.

The coordinates following a translation of 9 units to the left is (x - 9, y)

A reflection of the point (x - 9, y) about the x-axis is (x - 9, -y)

Therefore;

(4, 4) → (4 - 9, -4) = (-5, -4)

(8, 4) → (8 - 9, -4) = (-1, -4)

(6, 6) → (6 - 9, -6) → (-3, -6)

The image from the third transformation is (-13, -9), (-1, -4), (-7, -6), which corresponds to the first graph.

(Angles) Just 3 problems

Answers

Answer:

First attachment:

Angle Q and Angle S measure 61°

Second attachment:

Angle A measures 60°

Angle B and Angle D are congruent and measure 90°

Angle C measures 39°

Angle E measures 51°

Third attachment:

a. 3x+51=180, x=43

b. Angle 1 measures 129° and Angle 2 measures 51°

Step-by-step explanation:

First attachment:

If a triangle measures 180°, then you can subtract 58 from 180, then divide the answer by 2 to figure out the degree measure of Angle Q and Angle S because they both have the same measure.

180-58=122

122/2=61°

Second attachment:

Angle A has an angle to the right that measures 125°. If a straight angle measures 180°, then you can subtract 125 from 180 to find the measure of Angle A (60°).

Angle B and Angle D are opposite interior angles, so they are congruent. After finding the measure of Angle E, we can subtract the measure of Angle E and the third angle of the triangle (that is shown to measure 39°) from 180° to determine the measure of Angle D and Angle B. (You can do the same method to Triangle ABC to find the measure of angle B). After determining that Angle E measures 51°, you can determine that Angles B and D measure 90°.

Angle C measures 39° because Angle C and the angle that measures 39° are vertical angles, and therefore, are congruent.

Angle E has an angle to the right that measures 129°. If a straight angle measures 180°, then you can subtract 129 from 180 to find the measure of Angle E (51°).

Third attachment:

If the two angles are supplementary, then they add up to 180°.

a. Taking that into consideration, 3x (Angle 1) + 51 (Angle 2) = 180°

To solve for x, subtract 51 from both sides

3x+51=180°

    -51   -51

3x=129

Then divide 3x from both sides

3x/3=129/3

x=43

b. Angle 2 (51°) is already given, but you need to find out the measure of Angle 1. To find the measure of Angle 1, plug your x value into 3x.

3(43)=129°

Angle 1 = 129°

Hope This Helps!

First picture:
A = 59 angles in a straight line add up to 180
B = 82 angles in a triangle add up to 180
C = 39 opposite angles are equal
D = 90 angles in a triangle add up to 180
E = 51 angles in a straight line add up to 180

Second picture:
180 - 58 = 122
122/2 = 61

Third picture:
3x + 51 = 180
180 - 51 = 129
3x = 129
X = 43
Angle 1 = 129
Angle 2 = 51

Javier walks up to a tank of water that can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Javier first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water.
At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.

How many more minutes will it take for the tank to drain completely? Explain or show your reasoning.

How many minutes before Javier arrived was the water tank completely full? Explain or show your reasoning.

Answers

1)  Gallons per minute change is -2/3 gallons per minute  since it decreases by 2 gallons in 3 minutes

2)  we have 5 gallons and lose 2/3 gallons per minute

(2/3 gal/minute)(x minutes) = 5 gallons

x = 5(3/2) = 15/2 = 7.5 minutes to drain the other 5 gallons

3)  There were 10 gallons when the tank is full

    That is 3 gallons more than the 7 gals there when Jada arrived.

    (2/3)(x) = 3

    x = 3(3/2) = 9/2 = 4 1/2 minutes

The tank was full 4 1/2 minutes before Jada arrived

F.(405/19,1601/19)

G.(9,2/3)

H. (7, -3/2)

I. (-6,5)

Step-by-step explanation:

For all of these you are going to solve one of the equations for one of the variables. A lot of them are already solved (One equation has the variable already equal to the other side like B has -2x+8=y.

Then you are going to take that value and substitute it into the other equations.

Once you get the answer for that variable, plug the answer into the other formula and solve.

Finally, check your answers by plugging both variables into the formula.

For example A,

You already have one of the equations solved so you would plug in 3x-11 for y in the bottom equation to get 2x-3(3x-11)=-2

Now distribute and solve 2x-9x+33=-2

2x-9x=-7x and -2-33=-35

Divide both sides by -7

x=5

Now plug 5 into the first equation of y=3x-11 and solve to get y=3(5)-11=15-11=4

Finally, check your work by plugging your numbers into the first equation you worked with 2(5)-3(4)=-2. 10-12=-2. -2=-2
