a certain test is worth 135 points. how many points (rounded to the nearest point) are needed to obtain a score of 85%?

yanalaym [24]

To obtain a score of 85% on a test worth 135 points, one needs to get 115 points. By using proportions, we get the required value.

<h3>How to write proportions?</h3>

A proportion is defined as an equality between two ratios.

Consider two ratios a:b and c:d. Then, the proportion we can write,

a: b = c : d

Then, the simplification we have for this proportion is

a/b = c/d or ad = bc

<h3>Calculation:</h3>

It is given that, a certain test is worth 135 points.

One to get 85% on this test, he/she needs to get X number of points.

So, we can write the proportions as

X : 135 = 85 : 100

⇒ X/135 = 85/100

⇒ X = 85/100 × 135

∴ X = 114.75 ≅ 115 points

<h3>Given:</h3>

w= 6 units
h= 6 units
l= 10 units

w: width
h: height
l: length

The volume of the given triangular prism.

<h3>Solution:</h3>

Triangular prism is a 3 sided prism with same area of cross section with 2 triangular bases.

$\large\boxed{Formula: V= \frac{wl}{2}×h}$

Let's solve!

First, let's multiply width and height.

$6×6$

$= 36$

Now, we'll have to divide the answer by 2.

$\frac{36}{2}$

$= 18$

Then, multiply the answer by length.

$18×10$

$\large\boxed{V= 180 \: {units}^{3}}$

Hence, the volume of the given triangular prism is 180 cubic units.
