Answer:

Step-by-step explanation:

For m, I look for the greatest power of m that is in all of the expressions. Since the first has m^2, the second has m, and the third has m^4, the greatest power of m that is in all expressions is m.

For the number, I look for the greatest factor of 8, 4, and 10. A trick would be to look at the smallest number since the greatest common factor can only be less than or equal to the smallest number. So looking at 4, the factors are 1,2,4. 4 is not a common factor since it does not divide into 10, but 2 is so 2 is the greatest common numerical factor.

Combine 2 and m to get 2m.

Answer:

Step-by-step explanation:

8m² = 2×2×2×m×m

4m = 2×2×m

10m² = 2×5×m×m×m×m

Common are: 2×m = 2m

The area of a rectangle is 490490 in squaredin2. the ratio of the length to the width is 5 : 25:2. find the length and the width

Arlecino [84]

Let the width be 2w. Then the lenght is 5w. So:
(2w)(5w)=490
10w²=490
w²=49
w=±7
So, 2w=width=14 in; and 5w=length=35 in

WILL GIVE BRAINLY Find the perimeter of the figure below, in meters.

yan [13]

Answer:

$147.6\:\mathrm$

Step-by-step explanation:

The perimeter of a polygon is simply sum of the lengths of all sides of the polygon.

Therefore, we can find this polygon's perimeter by adding up the length of each of its sides:

$9.8+9.8+11.7+9.8+21.5+21+11.7+9.8+31.3+11.2=\boxed{147.6\:\mathrm{m}}$

Since there is a lot to keep track of, I'd recommend picking any side and moving clockwise/counter-clockwise until you get all sides.

Can you please help me with this

Vitek1552 [10]

Answer:

log9

Step-by-step explanation:

Using the rules of logarithms

logx + logy = log(xy)

logx - logy = log( $\frac{x}{y}$ )

log $x^{n}$ ⇔ nlogx

Given

2(log18- log3) + $\frac{1}{2}$ log $\frac{1}{16}$

= 2(log( $\frac{18}{3}$ ) ) + log $(\frac{1}{16}) ^{\frac{1}{2} }$

= 2log6 + log $\frac{1}{4}$

= log6² + log $\frac{1}{4}$

= log36 + log $\frac{1}{4}$

= log( 36 × $\frac{1}{4}$ )

= log9

A box of cereal states that there are 75 calories in a 34-cup serving. What is the unit rate for calories per cup? How many calo

xeze [42]

The unit rate is how many calories are in 1 cup of cereal.
Set up a proportion:
$\frac{75 cal}{3/4 cup} = \frac{X cal}{1 cup}$
Cross multiply and solve:
$\frac{3}{4} X = 75\\ 3X=300\\X=100$
There are 100 calories per cup of cereal.

To get the calories in 4 cups of cereal, simply multiply the unit rate of 100cals/cup by 4.
$100*4=400$
There are 400 calories in 4 cups of cereal.
