Help me solve this. Please, it's math.

Answer:

54.872

Step-by-step explanation:

volume of a cube = s³

where s = side length

side length given here is 3.8

so volume = 3.8³ = 54.872

Answer:

54.872

Step-by-step explanation:

3.8 * 3.8 *3.8

Answer:

77.5 cm²

Step-by-step explanation:

We need to find the surface area of the rectangular prism.

Total surface area = 2(lw + wh + lh)

where:

Given dimensions:

[tex]\textsf{length}=\sf 6\dfrac12\:cm=6.5\:cm[/tex]

[tex]\textsf{width}=\sf 2\dfrac12\:cm=2.5\:cm[/tex]

[tex]\textsf{height}=\sf 2\dfrac12\:cm=2.5\:cm[/tex]

Substituting these value into the formula:

[tex]\begin{aligned}\textsf{Surface area} & =\sf 2(6.5 \cdot 2.5+2.5 \cdot 2.5+6.5 \cdot 2.5)\\ & = \sf2(16.25+6.25+16.25)\\ & = \sf 2(38.75)\\ & =\sf77.5\:cm^2 \end{aligned}[/tex]

Therefore, 77.5 cm² of fabric is needed to cover the weight.

If [tex]$l$[/tex] be the length of cuboid, [tex]$b$[/tex] be the breadth of cuboid and [tex]$h$[/tex] be the height of cuboid, then its total surface area (TSA) of cuboid is given by,

[tex]\;\longrightarrow\boxed{\tt{TSA = 2(lb + bh + lh)}}[/tex]

A cuboid is also known as rectangular prism.

We need to find the surface area of the cuboid or rectangular prism whose length, breadth and height are given.

Now by using the formula of surface area nd substituting the given values, we get the following results:

[tex]\implies\tt{Surface\;area = 2(6.5 \times 2.5 + 2.5 \times 2.5 + 6.5 \times 2.5)}\\[/tex]

[tex]\implies\tt{Surface\;area = 2(16.25 + 6.25 + 16.25)}\\[/tex]

[tex]\implies\tt{Surface\;area = 2(38.75)}\\[/tex]

[tex]\implies\boxed{\pmb{\tt{Surface\;area = 77.5}}}\\[/tex]

Hence, this is our required solution for this question.

Answer:

A = l * w

Step-by-step explanation:

the length times width would be the area, so just make variables of each thing and then you are good! It would be important to note any more information that is given, like the ratio of the length and the width, in which case just add the respective coefficients based on the ratio (e.g 3:2 would mean 3l * 2w = A). Hope this helps!

Answer:

2 slices.

Step-by-step explanation:

Let's say that James' cake is essentially one half of Peyton's cake. 6 x 2 is 12, and 4 x 2 is 8. So James' must have eaten 8 slices while Peyton ate 2.

Step-by-step explanation:

[tex]\large\text{volume of a rectangular pyramid} =\frac{1}{3} \times \text{base} \times \text{height}[/tex]

                                                            [tex]=\frac{1}{3} \times \left( 5\times 5\right) \times 3[/tex]

                                                            [tex]=\frac{1}{3} \times \left( 25\right) \times 3[/tex]

                                                            [tex]=\frac{1}{3} \times \left( 75\right) =\frac{75}{3} =25[/tex]

Answer:

5 yards

Step-by-step explanation:

The volume V of a pyramid is one-third the area of the base B times the height h .

[tex]volume \: = \frac{1}{3} \times base \times height[/tex]

[tex] \frac{1}{3} \times 5 \times 3 = 5yards[/tex]

T= gt2 + v0t + h0 / h; where the yielding result will reveal the time when the object will reach the ground.

Answer:

767 96-29. to check your add.

Answer:

B) No, supplementary angles are either of two angles whose sum is 180 degrees.

C) Yes, the triangles are congruent because the triangles have exactly the same size and shape

Step-by-step explanation:

B) From the image below an 180 degree angle would be obtuse in which neither angle appears to be so they are not supplementary.

C) They are congruent because they are taking angles of the same angles as one another just on different sides of the shape.

Answer:

y=(.5)x+7

Step-by-step explanation:

Hello. For this question, they are asking us to find the equation of a line. A line has this form: y=mx+b.

For this question they will want us to give the answer with x and y as variables (letters) and m and b (the slope and y-intercept respectivly) with numerical values.

First, we can put in the point into the equation. The point given is (-10,2) so the x value is -10 and they y value is 2.

y=mx+b

2=m(-10)+b

Then we know that the slope is .5, so we can put that in as m.

2=(.5)(-10)+b

Solving for b, we get that it is equal to 7.

[2+5=b] b=7

Therefore, the equation for the line would be:

y=(.5)x+7

Answer:

You will end up on A 3 times, B 4 times, and C 5 times.

Answer:

31.) you put a dot on one and go to the right

32.) you put a dot on ten and go to the left

Step-by-step explanation:

the absolute value part is honestly just to throw u off, it also helps if you read it aloud. so for example in # 31. is saying the absolute value of b minus 5 is greater or equal to 1, you could also think of it as any number is greater or equal to one. hope that helps!

when dealing with an absolute value expression, let's keep in mind that the expression once we remove the bars it has a ± version, so if the expression were say hmmm |a + b| = 25, if we remove the bars we really have a duet, namely ±(a + b) = 25, same if we had |a + b| > 25, then ±(a + b) > 25.

Tis noteworthy, that unlike "equalities", inequalities vary mainly on that, when we divide or multiply or exponentialize by a negative value, the inequality sign does a horizontal flip, it changes, so let's proceed

[tex]\boxed{31}\\\\ |b-5|\geqslant 1\implies \pm(b-5)\geqslant 1\implies \begin{cases} +(b-5)\geqslant 1\\ b\geqslant 6\\[-0.5em] \hrulefill\\ -(b-5)\geqslant 1\\ b-5\stackrel{\stackrel{notice}{\downarrow }}{\leqslant} -1\\ b \leqslant 4 \end{cases}~\hfill 6~~\leqslant ~~ b~~\leqslant ~~4[/tex]

[tex]\boxed{32}\\\\ |-2r|\leqslant 10\implies \pm(-2r)\leqslant 10\implies \begin{cases} +(-2r)\leqslant 10\\ -2r\leqslant 10\\ r\stackrel{\stackrel{notice}{\downarrow }}{\geqslant} \cfrac{10}{-2}\\\\ r\geqslant -5\\[-0.5em] \hrulefill\\ -(-2r) \leqslant 10\\ 2r \leqslant 10\\ r\leqslant \cfrac{10}{2}\\\\ r \leqslant 5 \end{cases}~\hfill -5~~\leqslant~~ r ~~\leqslant~~5[/tex]

according to my calculator ! hope this helps

Answer:

try D 2,688

Step-by-step explanation:

14 x 12 x 16 = 2,688 my bad for the last one

Step-by-step explanation:

It is an equal step by step equation because the prism has equal sides, so you would just have to add all them up and too try to find the surface area, and you know how the bottom is ten so the top would be ten too.
