evablogger [386]

The jar has 138 grams of zinc.

Solution:

Given that , In a certain chemical reaction, the ratio of zinc to copper is 3 to 16.

A jar of the chemical contains 736 grams of copper.

We have to find how many grams of zinc does it contain

Let "n" be the grams of zinc needed for 736 grams of copper

Now, we know that,

16 grams of copper ⇒ 3 grams of zinc

Then, 736 grams of copper ⇒ n grams of zinc

So, by criss cross multiplication,

$n \times 16 = 3 \times 736$

16n = 3 x 736

16n = 2208

n = 138

Hence, the jar has 138 grams of zinc.

If line uw bisects angle tuv,, m angle tue = (13x-5) and angle wuv = (7x+31) find the value of x

scZoUnD [109]

The value of x will be 6

Explanation

According to the below diagram, UW is the angle bisector of ∠TUV

That means, $\angle TUW = \angle WUV$

Given that, $\angle TUW = 13x-5$ and $\angle WUV= 7x+31$

So, the equation will be......

$13x-5=7x+31\\ \\ 13x-7x=31+5\\ \\ 6x=36\\ \\ x=\frac{36}{6}=6$

So, the value of x will be 6.
