Answer:

We can say that it is a Rectangle

Step-by-step explanation:

Based on the image shown we can see the following. The Blue section is a 2D figure. We can also see that the sides cover the same length and height as the rectangular prism that encompasses it. Therefore based on the information that we gathered we can say that the cross section (blue shaded area) is a rectangle.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

The cross-section shown in a rectangular prism with the blue-shaded area is a rectangle.

Given that,

A rectangular prism with a cross-section is shown in the image.

Used the concept of rectangle which states that,

A rectangle is a two dimension figure with 4 sides, 4 corners, and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Now, by the given figure, the Blue section is a 2D figure.

And, the sides cover the same length and height as the rectangular prism

Hence, it shows a rectangle.

Therefore, the cross-section shown with the blue-shaded area in the figure is a rectangle.

Answer:

x=15/8

Step-by-step explanation:

Inverse variation is given by

xy = k

Substituting x=5 and y=12

5*12 = k

60 =k

Our original equation is xy = 60

Now let y=32

x*32 = 60

Divide each side by 32

32x/32 = 60/32

Divide top and bottom by 4

x = 15/8

Answer:

The fourth answer is the correct one.

Step-by-step explanation:

It cost $12 to download 3 videos, which works out to $4 per video.

Thus, k = $4/video.

The fourth answer is the correct one.

The proportional relationship is y = ($4/video)x, where x is the number of videos downloaded and $4 is the unit cost per video.

ANSWER

(1,7)

EXPLANATION

The given equations are:

1st: 3a + 6b = 45

and

2nd:2a – 2b = –12

Multiply the second equation by 3,

3rd: 6a – 6b = –36

Add the first and third equations.

6a+3a+6b-6b=45+-36

Simplify,

9a=9

a=1

Put a=1 in the second equation:

2(1) – 2b = –12

-2b=-12-2

-2b=-14

b=7

Answer:

The hawk reaches the rabbit at t=4.3 sec

Step-by-step explanation:

Let

h ----> is the height in feet

t ----> is the time in seconds

v ---> the initial velocity in feet pr second

s ----- is the starting height

we have

[tex]h=-16t^{2} +vt+s[/tex]

when the hawk reaches the rabbit the value of h is equal to zero

we have

[tex]v=55\ ft/sec[/tex]

[tex]s=60\ ft[/tex]

substitute

[tex]0=-16t^{2} +55t+60[/tex]

Solve the quadratic equation by graphing

The solution is t=4.3 sec

see the attached figure

For this case we must solve the following equation for x:

[tex]\frac {1} {3} (6x-15) = \frac {1} {2} (10x-4)[/tex]

We apply distributive property to the terms of parentheses:

[tex]2x-5 = 5x-2[/tex]

We subtract 5x on both sides of the equation:

[tex]2x-5x-5 = -2\\-3x-5 = -2[/tex]

Suamos 5 on both sides of the equation:

[tex]-3x = -2 + 5\\-3x = 3\\x = - \frac {3} {3}\\x = -1[/tex]

Answer:

[tex]x = -1[/tex]

It is similar to triangle LMN and has coordinates L′(12, −16), M′(8, −8), and N′(−24, 4)

EXPLANATION

The given triangle LMN with vertices L(6, −8), M(4, −4), and N(−12, 2).

Answer:

A

Step-by-step explanation:

Its the one that mostly makes sense

Answer:

the answer is A.  10/8 cubic in.

Step-by-step explanation:

V = LWH

length is 2 (1/3 in)

width is 3 (1/3 in)

height is 5 (1/3 in)

V = 2/3 in * 3/3 in * 5/3 in.

V = 10/9 cubic in.

The volume of the prism is 10 cubic inches, making the correct answer option b.

To find the volume of the prism made up of cubes each measuring 1/3 of an inch on one side, we first need to understand the volume of one cube.

The volume of a cube is calculated using the formula:

Given that each side of the small cube is 1/3 inch, we calculate:

Next, we need to determine the total number of these small cubes that make up the prism. Let's assume the prism consists of 270 of these small cubes.

The total volume of the prism is calculated by multiplying the volume of one small cube by the total number of cubes:

Thus, the correct answer is:

Answer:

[tex]F(x)=x^2-5[/tex]

Step-by-step explanation:

The parent function is [tex]G(x)=x^2[/tex].

The function F(x) is obtained when G(x) is shifted down by 5 units.

Hence we rewrite F(x) in terms G(x).

[tex]F(x)=G(x)-6[/tex]

Therefore the required equation is;

[tex]F(x)=x^2-5[/tex]

Answer:

4x

Step-by-step explanation:

The given product is;

[tex]\frac{2x^2}{3}(\frac{6}{x})[/tex]

This is the same as;

[tex]\frac{2x^2\times 6}{3\times x}[/tex]

We cancel out the common factors to obtain;

[tex]\frac{2x\times 2}{1\times 1}[/tex]

Multiply out to obtain;

[tex]\frac{4x}{1}[/tex]

Simplify

[tex]4x[/tex]

The second option is the correct choice.

Answer:

4x

Step-by-step explanation:

[tex]\frac{2x^2}{3}(\frac{6}{x})[/tex]

2x^2 can be written as 2*x*x

so the given expression becomes

[tex]\frac{2*x*x}{3}(\frac{6}{x})[/tex]

we cancel out x at the top and bottom

we know 6 divide by 3 is 2

[tex]\frac{2*x}{1}(\frac{2}{1})[/tex]

Now we multiply the numerator with numerator and denominator with denominator

(2/8)*(3/5)

=6/40

=3/20

Hope this helps!

Answer:

3/20

Step-by-step explanation:

2    3

-- * --- = 6/40, or 3/20

8    5

You may find it easier to multiply if you write the multiplicands as shown above, instead of 2/8 and 3/5.  Then:  2 times 3 is 6, and 8 times 5 is 40.

Reduce 6/40 to 3/20, your final answer.

Answer:

8 units

Step-by-step explanation:

Using the perpendicular bisector theorem, if we know that TQ is 8 units, then RT must be 8 units as well.

Answer:

8

Step-by-step explanation:

Step 1: Find the length of segment TS (I will call this as y)

Method: Pythagoras

10² = y² + 8²

 = 100-64 = y²

y = square root of 36

y = 6

Step 2: Use the method of Pythagoras to find RT = (x)

10² = x² + 6²

x² = 100 - 36

x = 64 square root

x = 8

d, they are the only animals that can do both

Answer:

guess it's C

Step-by-step explanation:

The answer is D. There are three notebooks each weighing 1.2 pounds. If you multiply three by 1.2 it is 3.6. There are two textbooks each weighing 3.4 pounds. 2 multiplied by 3.4 equals 6.8. Therefore, if you add the weight if the textbooks (6.8) and the weight of the notebooks (3.6) it is 10.4. Therefore the answer is D. Not C.

Translation

Step-by-step explanation:

You just move the shape down

Answer:

Step-by-step explanation: translation.

Translation is a term used in geometry to describe a function that moves an object a certain distance. The object is not altered in any other way. It is not rotated, reflected or re-sized. In a translation, every point of the object must be moved in the same direction and for the same distance.

Answer: 12

Step-by-step explanation:

You can use what is called geometric mean to solve this.

The hypotenuse of this triangle is split into two sections. One section corresponds to/equal to the altitude which is our "X", which corresponds to/equal to the second section.

You find "X" by using geometric mean and the proportion:

16/X=X/9

Then cross multiply to get 16 x 9= 144

then 144=x²

Solve for X.

X=12
