Answer:
8 -------$ 12
Step-by-step explanation:
There are different weights of oranges at a farmer’s market given in the question. Two oranges that is three dollars. So one orange will be of one point five dollars. Then five will be equal to seven point five dollars. Much easier form of calculation that is eight equal to seven point five plus one point five that is added three times. This gives the final value of eight oranges that is twelve dollars.
8------12$
2 orange = 3$
So 1 = 1.5$
5 = 7.5$
8 = 7.5 + 1.5 + 1.5 + 1.5
8 oranges = 12$
Answer:
The value of x = 20
Step-by-step explanation:
Given:
∠BOC = 3x - 15
∠COD = 2x + 5
Find:
The value of x
Computation:
⇔ ∠BOC + ∠COD = 90
⇔ 3x - 15 + 2x + 5 = 90
⇔ 5x - 10 = 900
⇔ 5x = 90 + 10
⇔ 5x = 100
⇔ x = 100 / 5
⇔ x = 20
The value of x = 20
Answer:
<h3>The length of y is 62.82 cm.</h3>
Step-by-step explanation:
We are given a right triangle with an angle 30°.
Opposite side of angle 30° is x and adjacent side is y.
Also, given length of side x=36.25 cm.
In order to find the value of y, we need to apply tangent trigonometrical ratio.
We know,

Therefore,

Plugging values of
and x=36.25, we get

Plugging value of
in above equation, we get

On multiplying both sides by y, we get

0.577y=36.25
Dividing both sides by 0.577, we get

y=62.82
<h3>Therefore, the length of y is 62.82 cm.</h3>
