Henry had 20 convertibles and 5 trucks in his miniature car collection. After Henry's aunt bought him some more miniature trucks

saw5 [17]

Answer:

Her aunt buy 75 trucks.

Step-by-step explanation:

Given:

Henry had 20 convertibles and 5 trucks in his miniature car collection. After Henry's aunt bought him some more miniature trucks, Henry noticed that a fifth of his collection were convertible.

Now, to find the trucks her aunt buy.

Let the total collection of Henry be $x.$

Number of trucks Henry had in his collection = 5.

Number of convertibles Henry had in his collection = 20.

As, Henry's $\frac{1}{5}$ collection were convertible.

Now, to get the total number of collection:

$\frac{1}{5}\ of\ x=20.$

$\frac{1}{5} \times x=20$

Multiplying both sides by 20 we get:

$x=100.$

Total collection of Henry = 100.

So, the total number of trucks he had in his collection is:

Total collection of Henry - number of convertibles Henry had in his collection.

$=100-20$

$=80.$

Hence, Henry had total 80 trucks in his collection.

And 5 trucks he had already in his miniature car collection.

Now, to get the number of trucks her aunt buy we subtract trucks he had already in his miniature car collection from the total number of trucks in Henry's collection:

Total number of trucks in Henry's collection - Number of trucks already in his miniature car collection.

$=80-5$

$=75.$

Therefore, her aunt buy 75 trucks.

PLEASE HELP!! I NEED THIS TO PASS.

Let's apply the Law of Cosines here. We want the measure of the angle opposite the side with length 16.

Call that angle C.

Then 16^2 = 36^2 + 28^2 - 2(36)(28)cos C.

Solving for C: cos C = 16^2 - 36^2 - 28^2
------------------------- = 0.904, and C = 0.44 rad
-2(28)(36) or C = 25.21 degrees

So each of the 2 equal angles shown has the measure 25.21 degrees.

Unfortunately, I don't know the direction we should go from this point on.

Glen invited 25 people to his birthday party.

Trava [24]

Answer:

20% of the invited people did not attend

Step-by-step explanation:

5 out of 25 people invited didn't attend Glen's party. That means the following:

$\frac{5}{25}$ people didn't come which simplifies to $\frac{1}{5}$
