Answer:

The factors of $13m$ are 13 and $m$ .

The factors of $2n$ are 2 and $n$ .

Step-by-step explanation:

We are asked to determine the factors of the given expression $13m-2n$ .

We know that factor is a number or quantity such that when multiplied with another number or quantity produces a given number or expression.

Since 13 is a prime number, so the factors of $13m$ are 13 and $m$ .

Since 2 is a prime number, so the factors of $2n$ are 2 and $n$ .

How do i find the mean of a group of number's

inna [77]

Lets say your numbers are these...

10,20,30,40,50,60,70,80,90 and 100

you would add those to get 650

Now how many numbers did you add?

You added 10

so now divided

650 by 10

you get 65

that is the mean of those numbers!

a certain shark has triangular teeth with a height that is 1 centimeter shorter than the base. if the area of one tooth is 1 squ

Advocard [28]

The Shark's teeth has a base of 2 cm and height of 1 cm.

Step-by-step explanation:

Step 1 :

Given,

the area of the shark's triangular teeth = 1 sq cm

Let b be the base and h be the height of the shark's triangular teeth.

We have the teeth's height is 1 cm short than the base

So h = b - 1

Step 2 :

Area of Triangle = ( $\frac{1}{2}$ ) × b × h = 1

Substituting h = b -1

( $\frac{1}{2}$ ) × b × (b-1) = 1

=> b² - b = 2 = > b²-b-2 = 1

Solving for b we have

(b-2)(b+1) = 0

b = 2 or b = -1

Since b is the base , we take the positive value as length/distance cannot be negative.

So b = 2

h = b - 1 = 2 - 1 = 1

h = 1

Step 3 :

Answer :

The Shark's teeth has a base of 2 cm and height of 1 cm.

Which equation BEST matches the model? A) 7/9 x 6/8 = 36 B) 7/9 x 3/4 = 21/36 C) 4 x 9 = 36 D) None of the above

patriot [66]

Whats the model because 7/9 × 3/4= 7/12 which also equals to 21/36
as 7/12 is the simplified version of 21/36 but then for c 4×9 =36 so I'm a bit confused my self but here's a bit of a start

Find the number of distinct triangles with the measurements a = 8, b = 14, and A = 30°.

Maslowich

Answer: 2

Step-by-step explanation:

By the law of sines,

$\frac{\sin B}{b}=\frac{\sin A}{a} \\ \\ \frac{\sin B}{14}=\frac{\sin 30^{\circ}}{8} \\ \\ \frac{\sin B}{14}=\frac{1}{16} \\ \\ \sin B=\frac{14}{16} \\ \\ B=\sin^{-1} \left(\frac{14}{16} \right), 180^{\circ}-\sin^{-1} \left(\frac{14}{16} \right) \\ \\ B \approx 61.04^{\circ}, 118.96^{\circ}$
