Given:

A combined figure of a triangular prism and a cuboid.

To find:

The volume of the finished object assuming it is empty inside.

Solution:

From the given figure it is clear that the dimensions of the cuboid are 6 cm, 8 cm and 5 cm.

So, the volume of the cuboid is:

[tex]V_1=length\times width\times height[/tex]

[tex]V_1=6\times 8\times 5[/tex]

[tex]V_1=240[/tex]

The volume of the cuboid is 240 cubic cm.

The area of a triangle is:

[tex]Area=\dfrac{1}{2}\times base\times height[/tex]

Thus, the base area of the triangular prism whose base is 8 cm and height 4 cm, is:

[tex]B=\dfrac{1}{2}\times 8\times 4[/tex]

[tex]B=16[/tex]

The volume of a triangular prism is:

[tex]V_2=Bh[/tex]

Where, B is the base area and h is the height of the prism.

The base area of the triangular prism is 16 square cm and the height is 5 cm. So, the volume of a triangular prism is:

[tex]V_2=16(5)[/tex]

[tex]V_2=80[/tex]

Now, the volume of the given figure is:

[tex]V=V_1+V_2[/tex]

[tex]V=240+80[/tex]

[tex]V=320[/tex]

Hence, the volume of the finished object is 320 cubic cm.

Answer:

7. 80 miles

8. F

Step-by-step explanation:

7. Jorge leaves 2 hours early, and is going 20 miles per hour. So before Marcos starts going, Jorge has gone 40 miles (2*20). Then, 1 hour later, Jorge is at 60 miles and Marcos is at 40 (because he goes 40 miles per hour in his car). Another hour later, Jorge is at 80 (60+20) and Marcos is at 80 as well (40 + 40). They will both have gone 80 miles when Marcus catches up.

8. You want to get a isolated.

A = h/2(a + b)

First, multiply both sides of the equation by the reciprocal of h/2.

2A/h = a + b

Then, subtract b from both sides.

2A-b/h = a

Answer: The answer is 42

Step-by-step explanation:

I did the test too :)

The weight of clothing for which the ratio of weight to dye is different from the other ratios is 42 pounds.

To determine which weight of clothing has a ratio of weight to dye different from the other ratios, we need to compare the ratios for each weight.

Let's calculate the ratios for each weight of clothing by dividing the weight of clothing (in pounds) by the cups of dye:

For 21 pounds of clothing: 21 pounds / 3 cups = 7 pounds per cup

For 42 pounds of clothing: 42 pounds / 9 cups = 4.67 pounds per cup

For 84 pounds of clothing: 84 pounds / 12 cups = 7 pounds per cup

For 105 pounds of clothing: 105 pounds / 15 cups = 7 pounds per cup

From the calculations, we can see that for weights of 21 pounds, 84 pounds, and 105 pounds of clothing, the ratios of weight to dye are the same, which is 7 pounds per cup. However, the ratio for 42 pounds of clothing is different, which is 4.67 pounds per cup.

Therefore, the weight of clothing for which the ratio of weight to dye is different from the other ratios is 42 pounds.

Matrices is an array of numbers, symbols and expressions arranged in rows and columns. Matrices can be used to solve system of equations. Many mathematical operations can be done on matrices such as addition, subtraction, multiplication, scalar multiplication and so on.

Addition and subtraction of two matrices can be done if they have the same dimensions.  This is done by simply adding or subtracting the corresponding entries in matrices.

If the width of the rectangular painting is one unit then the height of the painting will be 3/8 yards. Then the correct option is A.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

A painting is going to be reprinted as a poster.

The dimensions of the painting are 3/4 of a yard and 1/2 of a yard wide.

The poster company is trying to determine how big to make the poster For each yard of width,

Let h be the height of the poster. Then we have

[tex]\rm h \times 1 = \dfrac{3}{4} \times \dfarc{1}{2}\\\\h \ = \dfrac{3}{8}[/tex]

Answer:

Solution

Given -

polynomial p(x) = x³ - 23x² + 142x - 120

Now see the coefficients

coefficient of x³ is 1 x² is -23 x is 142 and then -120

when you'll add this coefficients

i.e.

1-23+142-120=0

When sum of the coefficient turn out 0 then x = 1

using x=1, x-1 = 0

devide the given polynomial p(x) = x³ - 23x² + 142x - 120 by x-1 you'll get rest two factors hence

Answer:

It is not foolish to fear—it is a matter of survival. The physical responses we have to objects or situations that we fear are often grouped together and characterized as a “fight or flight” instinct. Something alarms you, and instantly your brain causes a number of chemicals to be released into your bloodstream.

Answer:

Fear is already a part of human nature. In fact, fear is used as a defense mechanism of our ancestors long time ago. They used to live on caves, jungles, and not so sturdy shelters that would make them vulnerable enough to different predators. Thus having the feeling of fear saves them by backing down and to retreat unto safer places. Therefore I can say that it's not foolish to fear since it's already a part of us human beings. Even the bravest persons in the world have their own fears too. We can't just separate it from ourselves and let's just embrace it and try to do something to lessen it.
