1: The dimensions of a solid, rectangular block are in the ratio of 5 : 4:3. If the volume is equal to the volume of a cube of side 28 cm, find the length of the longest side of the cuboid, giving your answer correct to 1 decimal place.​

Answers

Answer 1

Answer:

Given, the dimension of a rectangular block in from of cuboid is in the ratio 5:4:3. The volume of the block is equal to the volume of cube of length 28 cm. Let the length , breadth and height of the cuboid be 5x , 4x and 3x respectively. Therefore the length of the longest side of the cuboid is = (7.2×5)cm=36 cm.

Answers: A, B, E

Reason:

Triangles A, B and E all have the angles 68 and 79 with a 3 unit side sandwiched between them. We can use the angle side angle (ASA) congruence theorem to prove those three triangles are identical copies of each other. They are rotated, reflected and shifted versions of one another. These tranformations are known as rigid transformations or isometries.

On the other hand, we can rule out choice C because the side between the angles is not 3 units long (even though the angles do match up). The same goes for choice D.

Answer:

[tex]\tan(X)=\dfrac{77}{36}[/tex]

Step-by-step explanation:

First we need to find the length of side WX.

To do this, use Pythagoras' Theorem:  [tex]a^2+b^2=c^2[/tex]

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

[tex]\implies WX^2+77^2=85^2[/tex]

[tex]\implies WX^2=85^2-77^2[/tex]

[tex]\implies WX=\sqrt{85^2-77^2}[/tex]

[tex]\implies WX=36[/tex]

Now use the Tan trig ratio:

[tex]\tan(x)=\sf \dfrac{O}{A}[/tex]

where:

[tex]x[/tex] is the angleO is the side opposite the angleA is the side adjacent the angle

From inspection of the triangle,

[tex]x[/tex] = ∠XO = 77A = WX = 36

Substituting these values into the tan trig formula:

[tex]\implies \tan(X)=\dfrac{77}{36}[/tex]

Therefore, the tangent of ∠X is [tex]\dfrac{77}{36}[/tex]

Answer:

77 / 36

Step-by-step explanation:

Finding the adjacent side

WX² = VX² - VW² [Pythagorean Theorem]WX² = (85)² - (77)²WX² = 7225 - 2929WX = √1296WX = 36

Tangent of ∠X

Opposite side / Adjacent sideWX / VW77 / 36

Three local stores are each selling their videos game consoles for the same price the table below shows how many consoles have been sold at each of the stores and the total sales dollars for the consoles.

Answers

Applying proportions, it is found that the discounted price of each console at store B is given by:

B. $210.80.

What is a proportion?

A proportion is a fraction of a total amount.

In this problem, at store B, 15 consoles sold for a total of $3,720, hence the price per console is of:

P = 3720/15 = $248.

A discount of 15% is applied, which means that the new price is 85% of the original price, hence:

P = 0.85 x 248 = $210.8.

Which means that option B is correct.

QueThe hieght of The statue of Liberty is 93m. This is about 27% of the Hancove building in Chicago. What is approximate Hieght of Hancove Building?

Answer Let height of Hancove Building be H.

Now according to question, 27% of H = 93m

27 / 100 (H) = 93m

H = 93 x 100 ÷ 27

H = 344.44m

Therefore, the approximate Hieght of Hancove Building is around 344.4m

Answer:

344.44 m

Step-by-step explanation:

Let the missing height is h.

We have 93 m is 27% of h, need to find the value of h

27% of h is 0.27h, the equation we need is below

0.27h = 93h = 93/0.27h = 344.44

-4+x=10 is 13 the solution

Answers

Answer:

No.

Step-by-step explanation:

You are trying to solve for x. Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides of the equation to isolate the variable, x:

-4 + x = 10

-4 (+4) + x = 10 (+4)

x = 10 +4

x = 14

x = 14, x ≠ 13, ∴ 13 is not a solution.

~

No 13 is not the solution. Add 4 to both sides to get x by itself.
So x minus 4 plus 4 equals
X
And
10 plus 4 equals 14
So x equals 14 not 13
