Help meeeeeeeeeeee:(

Vaselesa [24]

Answer:

1/3

Step-by-step explanation:

(1/3)^2x(1/3)^-1

so, we can write this as:

1/3 x 1/3 x 3/1

if calculated by cutting, the answer is 1/3

There is also an easier way to do this,

(1/3)^2 x (1/3)^-1

as the bases are same, the powers will be added.

2+(-1)

2-1

so,

(1/3)^1 or 1/3

A point on the ground is 50 feet from my house. The angle of elevation to the top of the house is 48∘. Find the height of the ho

Mumz [18]

Answer:

55.5 feet

Step-by-step explanation:

the scenario is attached in the form of a picture

We have to find h.

We will use the trigonometric ratio of tan to find the height of the house.

$tan\ 48 = \frac{h}{50}\\ 1.1106*50=h\\55.53=h$

Hence the height of the house is 55.53 feet

Rounding off to nearest 10th

height = 55.5 feet ..

The sum of five consecutive numbers is 700, what is the first number?

Feliz [49]

Answer:

The first number is 138.

Step-by-step explanation:

Let the first number be x.

Then since they are consecutive numbers, the second number will be (x + 1), the third (x + 2), the fourth (x + 3) and the fifth being (x + 4).

We are given that their sum is 700. Therefore:

$x+(x+1)+(x+2)+(x+3)+(x+4)=700$

Solve for x. Combine like terms:

$5x+10=700$

Subtract 10 from both sides:

$5x=690$

Divide both sides by five. Therefore:

$x=138$

The first number is 138.
