A rectangular prism has a volume of 750 cubic millimeters. Its length is 15

umka2103 [35]

Answer: 5 milimeters.

Step-by-step explanation:

The formula for calculate the volume of a rectangular prism is:

$V=lwh$

Where "V" is the volume, "l" is the lenght, "w" is the width and "h" is the height.

You know that the volume, the lenght, and the width of this rectangular prism are:

$V=750mm^3\\l=15mm\\w=10mm$

Substitutute these values into the formula and solve for the the height "h":

$750mm^3=(15mm)(10mm)h\\\\h=\frac{750mm}{(15mm)(10mm)}\\\\h=5mm$

A= -2 b= -6 c= 5 10c^2 + 4a^2 a(3a+b) 2b(3b-c)

lora16 [44]

First one :

10•5^2+4•-2^2=234

Second one :
-2(3•-2+-6)=24

−2((3)(−2)−6)
(−2)((3)(−2)+−6)
(−2)((3)(−2))+(−2)(−6)
12+12
24
Last one :

2•-6(3•-6-5)

(2)(−6)((3)(−6)−5)
((2)(−6))((3)(−6)+−5)
((2)(−6))((3)(−6))+((2)(−6))(−5)
216+60
=276

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
