Answer:

The surface area of a rectangular prism can be calculated using the formula:

Surface Area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the rectangular prism, respectively.

Given the dimensions of the rectangular prism as:

Length (l) = 38

Width (w) = 20

Height (h) = 20

Substitute the values in the formula to get:

Surface Area = 2lw + 2lh + 2wh

Surface Area = 2(38)(20) + 2(38)(20) + 2(20)(20)

Surface Area = 1520 + 1520 + 800

Surface Area = 3840 square units

Therefore, the surface area of the rectangular prism is 3840 square units.

Answer:

3840

Step-by-step explanation:

A=2(wl+hl+hw)=2·(20·38+20·38+20·20)=3840

Step-by-step explanation:

When translating a pre-image, there are some easy tricks you can use to figure out what the coordinates of the image are instead of drawing it out.

When translated to the right, add the number of units translated to the x-value.

This is because, when we move right on a coordinate plane, we move along the x-axis toward the positive numbers.

When translated to the left, subtract the number of units translated to the x-value.

This is because, when we move left on the coordinate plane, we move along the x-axis toward the negative numbers.

When translated up, add the number of units translated to the y-value.

This is because when we move up on the coordinate plane, we move along the y-axis toward the positive numbers.

When translated down, subtract the number of units translated to the y-value.

This is because when we move down on the coordinate plane, we move along the y-axis toward the negative numbers.

This is how I solved this problem. Apply these tricks and you will see that you will get the correct answer.

I hope this will help you! :)

Answer: 76.5

Step-by-step explanation: First of all, you should divide all of the shapes into 1 shape. That leaves you with 3 separate shapes to find the area to. First, let's start at the bottom rectangle. The area of that rectangle is 42. Now, lets to the middle rectangle. 4x7=28, which is the area of that rectangle. Now, we do the triangle. We have to find out the side length, but we know that the bottom length is 13. So, we add 6+7 to get that specific length (13). Because this shape is a triangle, we divide 13 by 2 (6.5). Finally, we add 42+28+6.5, and we get 76.5. Hope this helped!

Answer:

The volume of the Styrofoam collar is 1583.36

Hope this helps!

Step-by-step explanation:

The volume of a cylinder is [tex]\pi r^{2} *h[/tex].

First, find the volume of the entire cylinder : [tex]\pi[/tex] × [tex]5^{2}[/tex] × 24, which would give us 1884.95559... . Find the volume of the smaller cylinder ( [tex]\pi[/tex] × [tex]2^{2}[/tex] × 24 ) which would be 301.5928947... . Subtract the two get 1583.36269745... .

73*4 would = 292. Therefore, none of the following 'simplified' expressions would equal to that amount.

Answer: 56

Step-by-step explanation

well you could break up this "shape"into multiple different parts (already broken) you want to find the area of all the shapes then add the areas.

first lets start off with the two triangles at the top the area for a triangle is base x height divided by 2, the base would be  because of the 5 and the 2 at  the edge of the triangle and the height would be 4 because of the 10 at the top minus the 6

for this case we wouldn't divide by 2 because there are 2 triangles, so there is no point. ( 7 X 4 = 28)  

then we would move onto the large rectangle, the area of a triangle is base x height, base=4 height=5 (4 x 5 = 20)

then we move onto the smaller rectangle using the same area formula, base=2 because if you look at the 6 on the top and minus the 4 of the large rectangle. height =3 (2x3=6)

and the last one the small triangle, for this we would use the same formula ( base x height divided by 2) we are dividing by two because there is only 1 triangle. base=2 and height=2 because of the five on the right minus the 3 *height of the smaller rectangle* so

(2X2 divided by 2= 2)

then we add them all up, 28 + 20 + 2 + 6 = 56

Answer:

The image coordinates of K′ if the preimage is reflected across y = −7 is (-4, -8)

Credit: first answer by MrRoyal

The coordinates of point M' if the preimage is reflected

across y = −3 would be M'(-1, -2).

There are three types of translations -

reflection

rotation

dilation

Given is that a Polygon JKLM is drawn with vertices J(−4, −4), K(−4, −6), L(−1, −6), M(−1, −4). We have to find the image coordinates of M′ if the preimage is reflected across y = −3.

The reflection of point (x, y) reflected across the line y = a is (x, 2a - y)

So, we can write the coordinates of point M' if the preimage is reflected

across y = −3 would be -

M(-1, -4) → M'(-1, 2 x - 3 + 4)

M(-1, -4) → M'(-1, -2)

Therefore, the coordinates of point M' if the preimage is reflected

across y = −3 would be M'(-1, -2).

Reason:

The numerator is [tex](2.1)^5[/tex]

Raising that to the third power gives

[tex]((2.1)^5)^3 = (2.1)^{5*3} = (2.1)^{15}[/tex]

We multiply the exponents. The general rule is

[tex](a^b)^c = a^{b*c}[/tex]

Use that same rule to cube the denominator.

[tex]((0.9)^4)^3 = (0.9)^{4*3} = (0.9)^{12}[/tex]

Therefore,

[tex]\left(\frac{(2.1)^5}{(0.9)^4}\right)^3=\frac{((2.1)^5)^3}{((0.9)^4)^3}\\\\=\frac{(2.1)^{5*3}}{(0.9)^{4*3}}\\\\=\frac{(2.1)^{15}}{(0.9)^{12}}\\\\[/tex]

In short

[tex]\left(\frac{(2.1)^5}{(0.9)^4}\right)^3=\frac{(2.1)^{15}}{(0.9)^{12}}\\\\[/tex]

74% percent of the students read less than six magazines

percentage, a relative value indicating hundredth parts of any quantity.

A histogram shows the number of magazines read last month by the students in a class

The total number of students are 2+15+3

Number of students=23

Number of students read less than six magazines is 17

Now let us find 17 is what percent of 23

x/100×23=17

23x=1700

Divide both sides by 23

x=1700/23

x=73.9

x=74%

Hence, 74% percent of the students read less than six magazines

Answer:

Answer is B)

Step-by-step explanation:

Josiah's mistake is (b) He did not multiply the numerator and denominator by the correct number to equal 1,500

The proportion is given as:

Multiply both sides by 1500

Evaluate the expression on the right-hand side

Multiply 10 by 1500 on the left-hand side

Divide 15000 by 20 on the left-hand side

Rewrite the equation as:

From the question, we can see that the products are not well carried out.

Hence, Josiah's mistake is (b)

He got the  rock songs part right. He did not multiply the numerator and denominator by the correct number until 1500.

The statements that are true about Josiah's solution are:

He correctly found the proportion of rock songs  by setting  the ratio (number of rock songs in the sample) / (total number of songs in the sample) = (number of rock songs in the MP3 player) / (total number of songs in the sample). sample MP3 player) and solving for x:

Start Fraction 10 over 20 EndFraction = Start Fraction x over 1500 End Fraction.

Initial fraction 10 times 30 over 20 times 30 final fraction = initial fraction x over 1500 final fraction.

300 = x.

 He didn't hit the average of the  rock songs right because the average of 4 and 6 is 5, not 300.  

He did not multiply the numerator and denominator by the correct number to 1500 because he should have multiplied both by 75 instead of 30 to get:

Initial fraction 10 times 75 over 20 times 75 final fraction = initial fraction x over 1500 final fraction. He did not have to divide 10 by 2 when he determined the ratio, because the ratio is already in its simplest form. So the real arguments are:

He got the  rock songs part right. He did not multiply the numerator and denominator by the correct number until 1500. He did not have to divide 10 by 2 to determine the ratio.
