Find the factor pairs of each number. 30

Mathematics
1 answer:

6 0
To determine the factor pairs for the number 30, simply find out the smallest set of numbers that will multiply to give 30, you would need to break down composite numbers to do this.

30 = 6 • 5 = 2 • 3 • 5.

These all are prime numbers that when multiplied together equals 30.

So, I need some help with these scatter plot questions. (basically free points because these might be easy for you!) (20 points)

Hello,

I have a graphing calculator so this will be easy for me to answer and explain how to figure these out. Here we go!

1. Well on a Ti - 84 plus calculator it says graph then you put in thee equations for each and C and D are already incorrect cause they go straight up and B is incorrect because it is a straight line on the top going straight. In this case your looking for a line that goes through the dots. And the answer would be A) Y = 1/2x + 7.

2. B) Then umber of accidents were reduced by 0.67 per month for every additional driver in the program.

3. Key: Y means yes N means no. Plot A had 1 disease present and 2 not present. Plot B has 3 diseases present and 1 disease not present.

4. Category A had 36 groups in group 1. and Category B had 12 groups in group 1. Easy!

Please mark Brainliest!

Hope I Helped!

Have a fantastic Day!

A cone has a diameter of 3 inches the cone holds 12 cubic inches of water to the nearest in what is the height
LUCKY_DIMON [66]

Answer:

5 inches

Step-by-step explanation:

A cone's volume can be found using the formula V = \frac{1}{3} \pi r^2 h. If the cone has a diameter of 3 inches then its radius is half r= 1.5 inches. Substitute r = 1.5 and V = 12 cubic inches.

V = \frac{1}{3} \pi r^2 h \\12 = \frac{1}{3} \pi (1.5)^2 h \\12 = \frac{1}{3} \pi (2.25) h\\12 = 2.355h\\5.10 = h

This means the height of the cone is 5.10 inches or to the nearest inch 5 inches.

Item 6 for what value of a is 8x−8+3ax=5ax−2a an identity?
Readme [11.4K]

Let's rewrite the expression as

8x+3ax-5ax = 8-2a \iff 8x - 2ax = 8-2a \iff 2x(4-a) = 2(4-a)

So, if a \neq 4, you may divide both sides by 4-a, the equation becomes 2x=2, and the only solution is x=1, which means that this is not an identity (an indentity is tautologically true, no matter the value of x).

If instead a = 4, you are multiplying both sides by zero, so the equation becomes

2x \cdot 0 = 2 \cdot 0 \iff 0=0

So, it doesn't matter which value for x you choose, because you will always end up with 0=0, which is obviously always true.

Given AB=10cm, CD=11cm, and AD=39cm, find the length of BC
liraira [26]

<u>Answer:</u>

BC = 18 cm

<u>Step-by-step explanation:</u>

As we can see from the diagram:

AB + BC + CD = AD

⇒ 10 cm + BC + 11 cm = 39 cm

⇒ BC + 21 cm = 39 cm

⇒ BC = 39 cm - 21 cm

⇒ BC = 18 cm

For which value of theta is sine theta = negative 1?
Ivan

Answer:

1) 270 degrees

2)  pi/4 rad

Step-by-step explanation:

1.) For which value of theta is sine theta = negative 1?

Given

sintheta = -1

theta = arcsin(-1)

theta = -90degrees

Since sin is negative in the third and 4th quadrant

In the third quadrant, theta = 180 + 90 = 270degrees

In the fourth quadrant, theta = 360 - 90 = 270 degrees

Hence the required value of theta is 270degrees

2) Given the radius of the circle to be 1, the y axis value will also be 1 units

Opposite = 1

adjacent = 1

hyp = √1²+1²

hyp = √2

sin theta = opp/hyp

sin theta = 1/√2

theta = arccsin(1/√2)

theta = 45 degrees

Express in radians

45 degrees = pi/4 radians

Hence the required angle in the first quadrant is pi/4 rad
