Answer:

About 20 - 19.75

Step-by-step explanation:

Answer:

19.75 cm

Step-by-step explanation:

Since l=4w, plug in 79 for l.

79=4w

79/4=19.75

w=19.75

Step-by-step explanation:

For #7 and #8, they have given you the answer of the product but without decimals.

You can just add up all the decimal places for this kind of multiplication.

For example, 6.543 and 2.6 have 4 decimal places in total (underlined), so just count four: 17.0118.

==========================================================

Explanation:

Let's use (x,y) notation to denote the results of the two dice. So x is the first dice value and y is the second. Something like (2,1) means we rolled a '2' on the first die, and a '1' on the second die. The order matters.

We want both x and y to be odd, and we also want x+y < 5.

Here are all of the ways to fit those conditions:

There are 3 ways to achieve this goal out of 6*6 = 36 ways to roll two dice without any restriction. The probability we're aiming for is 3/36 = 1/12

Side note: 1/12 = 0.0833 = 8.33% approximately.

Step-by-step explanation:

Answer:

This probaly sounds a little confusing

Step-by-step explanation:

1 day = 10 laps

1 lap = 400 meters

1 km = 1000 meters

12 km = ? days

We can use this information to find out a lot that we don't know.  

HOW MANY METERS PER DAY??

In order to find the number of meters in a day, we think, "She ran 400 meters 10 times... 400 times 10... that's 4000 meters in one day."

1 day = 4000 meters (10 x 400 meters)

HOW MANY KILOMETERS PER DAY?

In order to find the number of km in a day, we can think, "One thousand is a kilo. There are 4 'one thousand's in 4000. Kali ran 4 kilometers (literally 4 thousand meters) per day.  

1 day = 4 km (4000 m / 1000)

From here you can solve simply by thinking "How many 4km does it take to get to 12km?"

4 x ? = 12

? = 12 / 4

? = 3

Answer:

41

Step-by-step explanation:

each page holds 7 discs. the alb holds 700 discs. that means there are 100 pages. 69% of the pages are empty so therefore 41 pages are filled.

Answer:

41 purple marbles

Step-by-step explanation:

x= amount of purple marbles

3x+x=164

4x=164

x=164/4=41

Answer:

see explanation

Step-by-step explanation:

(a)

The area is calculated as length × breadth

area = 2x(2x + 6) ← distribute

       = 4x² + 12x

(b)

area = x(x + 4) ← distribute

       = x² + 4x

(c)

shaded area = 4x² + 12x - (x² + 4x)

                      = 4x² + 12x - x² - 4x ← collect like terms

                      = 3x² + 8x

Area of the composite figure can be find by using additive areas method and subtractive areas method

Composite geometric figures are made from two or more geometric figures. The composite figure below is made from parts of a rectangle and a circle

Since, Area is the quantity that expresses the extent of a region on the plane or on a curved surface.

Area of the composite figure can be find by using two methods,

Additive areas method and Subtractive areas method

In Addictive areas method

Break the composite shape into basic shapes

Find the area of the each basic shapes

Add all the areas of basic shapes together

In Subtractive areas method

Break the composite shape into basic shapes. That shape maybe larger than the composite shapes.

Find the area of the each basic shapes

Area of the composite shape will be the difference between the area of the larger shape.

Hence, the area of  the composite figure can be find by using additive areas method and subtractive areas method

~Answer~

Substitute your numbers:

y = 5x

For the first one, y equals 5, so substitute 5 for y.

So, 5 = 5x.

What multiplied by 5 gives 5? The answer is 1.

So, the first one is 1.

Do the same for all the others.

So, 4 = 5x.

4 = 5(4/5)

As a decimal that equals 0.8.

For the last one, I can't tell if that is saying 2 or .2 so I'll do both.

for 2, you will do 2 = 5x and for .2, you will do .2 or 0.2 = 5x.

For 2, it would be 2/5 or 0.4.

For .2 or 0.2, it would be 0.04.

So,

x                                                             y

1                                                             5

4/5 or 0.8                                             4

0.4 if it is 2 and 0.04 if it is 0.2.        2

(looking back, I'm pretty sure it was just 2 and not .2)

I hope this is what u were looking for, if not I'm so sorry for a useless answer.  I wasn't completely sure whether I was doing it right since I haven't done these types of math problems in some time.
