Answer:

$x = \sqrt{\frac{7}{2} }$

Step-by-step explanation:

Explanation

From given graph

AC = √7

Given angle ∝ = 45°

$cos\alpha = \frac{adjacentside}{Opposite side}$

$cos45 = \frac{x}{\sqrt{7} }$

$\frac{1}{\sqrt{2} } = \frac{x}{\sqrt{7} }$

$x = \frac{\sqrt{7} }{\sqrt{2} }$

$x = \sqrt{\frac{7}{2} }$

x = 1.8708

Vesnalui [34]

Answer:

21 grapes.

Step-by-step explanation:

We have been given that Tyrell ate twice as many grape as Katy. Lucy ate half as many grapes as Katy. Katy ate 6 grapes. We are asked to find the total number of grapes that all of them eat in all.

First of all, we will find twice of 6 grapes to find number of grapes eaten by Tyrell.

$\text{Grapes eaten by Tyrell}=2\times 6$

$\text{Grapes eaten by Tyrell}=12$

Now, we will find half of 6 to find number of grapes eaten by Lucy.

$\text{Grapes eaten by Lucy}=\frac{6}{2}$

$\text{Grapes eaten by Lucy}=3$

$\text{Grapes eaten by them in all}=6+12+3$

$\text{Grapes eaten by them in all}=21$

Therefore, the three of them eat 21 grapes in all.

nirvana33 [79]

Answer:

Both give - 6=5x

Step-by-step explanation:

First equation 2x-6=7x

When you solve it, it becomes :

2x-6=7x

Subtract 2x both sides

2x-2x-6=7x-2x=

-6=5x

2)5x-6=10

5x-5x-6=10x-5x

-6=5x
