1200 bricks each of 0.075m3 volume are required to construct a wall of length 25m and height 9m. Find the breadth of the wall.​

Answers

Here's the solution,

Volume of wall :

=》total bricks × volume of each brick

=》1200 × 0.075 m³

=》90 m³

volume of wall :

=》lenght × width × height

=》25 × 9 × width

=》225 × width

now, by equating the volumes, we get

( since they are volume of same wall )

=》225 × width = 90

=》width = 90 ÷ 225

=》width of wall = 0.4 m

I think it’s 1!


Because when you look at line y, you go down to where it meets up with line x, (y is negative numbers until it meets with line x) after that it isn’t a negative number and it turns into positive numbers. So it’s 1! I’m so sorry if this is wrong!

A college professor hands out a list of 10 questions, 5 of which will appear on the final exam for the course. One of the students taking the course is pressed for time and can prepare for MATH 270 Assignment 2 W. Li 2 only 7 of the 10 questions on the list. Suppose the professor chooses the 5 questions at random from the 10. a) What is the probability that the student will be prepared for all 5 questions that appear on the final examination

Answers

Answer:

21 / 252

Step-by-step explanation:

Recall : nCr = n! ÷ (n-r)!r!

The total possible outcome ; 5 questions out of 10

10C5 = 10! ÷ 5!5! = (10*9*8*7*6)÷(5*4*3*2*1) = 252

Required outcome :

All 5 questions set being from the 7 questions covered and 0 from the 3 left uncovered

7C5 * 3C0

7C5 = 7! ÷ 2!5! = (7*6) ÷ (2*1) = 21

3C0 = 3! ÷ 3!0! = 1

Probability = required outcome / Total possible outcomes

P(All 5 questions prepared for appears) :

[7C5 * 3C0] ÷ 10C5

(21 * 1) / 252

= 21 / 252

Step-by-step explanation:

1. x - 1 = [tex]\frac{-1}{2}[/tex]

    x = [tex]\frac{-1}{2}[/tex] +1

    x = [tex]\frac{1}{2}[/tex]

2.  8x - 5 =9

8x = 9 - 5

8x = 4

x = [tex]\frac{4}{8} = \frac{1}{2}[/tex]

3.  2[tex]x^{3}[/tex] = [tex]\frac{1}{4}[/tex]

     [tex]x^{3}[/tex] =  [tex]\frac{1}{4}[/tex] x [tex]\frac{1}{2}[/tex]

What is Right Angled Triangle?

Right angled triangle are those triangle for which one of the angle is 90 degrees.

For any angle, X, in a right triangle, trigonometric ratios are defined as,

sin X = opposite side / hypotenuse

cos X = adjacent side / hypotenuse

tan X = opposite side / adjacent side

Given is a table which represents the sine, cosine and tangent of two angles in a right angled triangle.

Let x and y be the two angles.

sin x = 0.819, cos x = 0.573 and tan x = 1.428

x = sin⁻¹ (0.819) = cos⁻¹ (0.573) = tan⁻¹ (1.428) = 54.98° ≈ 55°

The sum of the interior angles of a triangle is 180°.

In a right triangle, one angle is already 90°.

Sum of the other two angles = 180° - 90° = 90°.

One angle is got to be 55°.

Then the other angle will be 90° - 55° = 35°.

The sine of 55° is equal to the cosine of 35° and the sine of 35° is equal to the cosine of 55°.

This is because that the opposite side of one angle will be the adjacent side of the other angle.

And the hypotenuse is constant.

sin 55=opposite side/hypotenuse and cos 35=adjacent side/ hypotenuse

Opposite side of 55° and adjacent side of 35° are same.

So they have the same values.

Hence the measures of the angles are 55° and 35°.
