Mathematics

stira [4]3 years ago
7 0

Answer:

10 + (2 x 3)^2 / 4 x (1/2) ^3

First do the parentheses

2 x 3 = 6

1 / 2 = 0.5

We are left with

10 + 6^2 /4 x 0.5^3

Do exponents

6 x 6 = 36

0.5 x 0.5 x 0.5 = 0.125

10 + 36 / 4 x 0.125

Divide by 4 and multiply by 0.125

36 / 4 = 9

9 x 0.125 = 1.125

We are left with

10 + 1.125 = 11.125

The answer is 11.125

Find the value of y in the given triangle
Andre45 [30]

Given:

In the given triangle,

With respect to y, Perpendicular = 10 cm and Base = 8 cm

To find the value of y.

Formula

By Trigonometric Ratio we get,

tan\theta = \frac{Perpendicular}{Base}

Now,

Putting the values of perpendicular and base we get,

tan\theta = \frac{10}{8}

or, \theta = tan^{-1} (\frac{10}{8})

or, \theta = 51.34 ^\circ

Rounding off to the nearest tenth, we have;

\theta = 51.3 ^\circ

Hence,

The value of y is 51.3°.

A positive number is 3 times another number.
Juli2301 [7.4K]

Answer:

The smaller number can be 8 or \frac{1}{5}.

Step-by-step explanation:

Consider the provided information.

let the larger number is x and the smaller number is y

A positive number is 3 times another number.

3y=x

If we add 2 to the larger and 5 to the smaller, then one of them becomes 2 times the other.

Case I: If 2nd number is 2 times to the first number.

x+2=2(y+5)

Substitute the value of x.

3y+2=2y+10

y=8

Now substitute the value of y in 3y=x

3(8)=x

x=24

Therefore, the smaller number is 8.

Case II: If 1st number is 2 times to the second number.

2(x+2)=y+5

Substitute the value of x.

2(3y+2)=y+5

6y+4=y+5

5y=1

y=\frac{1}{5}

Therefore, the smaller number is \frac{1}{5}.
