Answer:

question 1 asks about the volume  and question 2 asks about the surface area.. I can't see all of question 3... soo I'll give  you the first two only

Step-by-step explanation:

this seems like it would be easier to figure out.. if we did the volume of the block that would fit around the odd shape of the foam soooo

the block would be 10 inches tall by 36 inches long by 20 inches in depth

use a calculator.. 10 x 36  x 20 = 7200 [tex]inches^{3}[/tex] is  the volume... of just a block that would fit perfectly over that foam structure.. now subtract the two pieces that are not part of the block.. the long rectangle and the triangle off the end.

the first one to subtract is a block that is 8  x 5 x 20= 800

the second piece to subtract is the triagle block that is 18 x 8  so the formula for the area of a triangle is 1/2 base * height = 1/2 (18*8)= 72

7200-800-72=[tex]inches^{3}[/tex]  is the total volume of the shape

the surface area is just add up each flat area of the shape

side = 36x10 - 8x5 - 1/2(8x20)

side = 240

5x20 + 8x20 + 5x20 + 10x20 + 20x20 + 2x20 +36x20 + 2(side)= 2200 [tex]inches^{2}[/tex]

Step-by-step explanation:

Step-by-step explanation:

The cubic function passes the x-axis only once,

so there is 1 distinct real zeroes and 2 complex zeroes.

The function has only one real zero and two complex zeroes. Then the correct option is D.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The graph of the cubic function is shown.

The intersection of the curve with the x-axis is known as the zeroes of the function.

From the graph, the curve that cut the x-axis is only one point. Then the function has only one real zero and two complex zeroes.

Thus, the correct option is D.

More about the function link is given below.

Answer:

∠ QPM = 68°

Step-by-step explanation:

The measure of the chord- chord angle QPM is half the sum of the arcs intercepted by the angle and its vertical angle, that is

∠ QPM = [tex]\frac{1}{2}[/tex] ( LM + LK )

            = [tex]\frac{1}{2}[/tex] ( 76 + 60)°

           = [tex]\frac{1}{2}[/tex] × 136°

           = 68°

Answer:

35 grams

Step-by-step explanation:

The ratio of zinc to copper is 3 to 11

A jar of chemical contains 385 grams if copper

Therefore the number of grams of zinc it contains can be calculated as follows

3/11= x/385

11x= 385

x= 385/11

= 35 grams

Hence the chemical contains 35 grams of zinc

The volume, in cubic in, of a cylinder with a height of 15 in and a base radius of 5 in is 1177.5 cu.in.

A fixed planar closed curve intersects a surface traced by a straight line traveling parallel to a fixed straight line , is called as a Cylinder.

It is given that the height of the cylinder = 15 inch

Base radius = 5 inch.

The volume of the cylinder is given by

V = π r²h

V = π 5² * 15

V = 3.14 *25 *15

V = 1177.5 cu.in

The volume, in cubic in, of a cylinder with a height of 15 in and a base radius of 5 in is 1177.5 cu.in.

Bar Graph is useful because its easy to see, and if you look at it after 2 years, you could of know about it in a few seconds. Its usually correct to use bar graphs. Like you'll see bar graph's more often than picture graphs.

Picture graphs is useful because displaying data would be easier. Memorizing it would be better and possible.

I don't really have much to say about picture graphs, so its reasonable to give the other person brainliest.

Answer:

[tex]\bold{\angle B = 51^\circ}[/tex]

Step-by-step explanation:

Given a [tex]\triangle ABC[/tex] such that [tex]\angle A[/tex] is the largest.

[tex]\angle A[/tex] is equal twice of [tex]\angle B[/tex]

[tex]\angle C[/tex] is 10 more than one third of [tex]\angle B[/tex]

To find:

Measurement of [tex]\angle B[/tex].

Solution:

Let [tex]\angle B =x^\circ[/tex]

As per question statement:

[tex]\angle A = 2\times \angle B=2x^\circ[/tex]

[tex]\angle C = \dfrac{1}{3}\angle B +10= \dfrac{1}{3}x +10 ^\circ[/tex]

Using the angle sum property of a triangle i.e. sum of all the three internal angles is equal to [tex]180^\circ[/tex].

[tex]2x+x+\dfrac{1}{3}x+10 = 180\\\Rightarrow \dfrac{10}{3}x =170\\\Rightarrow x = 51^\circ[/tex]

Therefore, the answer is:

[tex]\bold{\angle B = 51^\circ}[/tex]

Step-by-step explanation:

I'm not 100% sure that this is correct but it's the only one that makes sense in my brain. But I'm going to explain anyways.

2x + 6 = 3x - 8 (initial equation)

It could also be D. Subtract 6 from each side, which is why I'm confused. Hopefully this helps, sorry if it doesn't. But happy holidays! :))

Answer:

Well its the same formula for the area of a triangle, nothing changes.

a=B*H/2

Step-by-step explanation:

Even if the shape changes, in order to find the area of one side of a triangle, locate the base and height and multiply those two together. After that, use that product and divide it by 2 to find the area of that triangle.
