PLEASE SOLVE AND EXPLAIN I WILL MARK BRAINIEST AND GIVE 100 points

Answer:

300

Step-by-step explanation:

Two triangles with b = 12 and h = 9

Their total area is 2*(1/2bh) = 2* (1/2(12)(9)) = 108

Other two triangles with b = 12 and h = 16

Their total area is 2*(1/2bh) = 2* (1/2(12)(16)) = 192

Sum of area is all four triangle areas combined = 108 + 192 = 300

Step-by-step explanation:

circumference(c)=43.96

2πr=43.96

r=43.96÷2π

radius ( r)=7

Answer:

Around 72.8 inches

Step-by-step explanation:

We are given the infomation that Chris is 185 centimeters tall.

There are 2.54 centimeters in an inch.

185/2.54 = 72.8346 ≈ 72.8

Chris should be around 72.8 inches.

Hope this helps.

Chris should be around 72.8 inches tall.

Here, we have,

given that,

Scott is 72 inches tall and Chris is 185 centimeters tall

We are given the information that Chris is 185 centimeters tall.

now, we know that,

There are 2.54 centimeters in an inch.

Since 1 inch = 2.54 centimeters

all we need to do is to divide 185 by 2.54

i.e. 185/2.54 = 72.8346 ≈ 72.8

The answer will be 72.8.

Chris should be around 72.8 inches.

Asking for 50% of something is like asking for half, therefore your answer is 10. :)

Answer:

(1, 5 )

Step-by-step explanation:

Given the 2 equations

9x + 3y = 24 → (1)

10x - 2y = 0 → (2)

Multiplying (1) by 2 and (2) by 3 and adding the result will eliminate the y- term

18x + 6y = 48 → (3)

30x - 6y = 0 → (4)

Add (3) and (4) term by term to eliminate y

48x + 0 = 48

48x = 48 ( divide both sides by 48 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (1)

9(1) + 3y = 24

9 + 3y = 24 ( subtract 9 from both sides )

3y = 15 ( divide both sides by 3 )

y = 5

solution is (1, 5 )

Answer:

Blue

Step-by-step explanation:

First, we need to find the LCD (Least common denominator)

Rewriting input as fractions if necessary:

1/10, 1/4, 1/5

For the denominators (10, 4, 5) the least common multiple (LCM) is 20.

Therefore, the least common denominator (LCD) is 20.

Now, we convert:

Red Marbles: 1/10 = 2/20

Blue Marbles: 1/4 = 5/20

Yellow Marbles: 1/5 = 4/20

As we can see, blue has the most. Now we have our answer! Good luck!

Answer:

The length of the rectangle is 28 inches.

Step-by-step explanation:

We have that the width (W) of a rectangle is half of the length (L) of the rectangle:

[tex] W = \frac{1}{2}L [/tex]  (1)

Also, the perimeter is 84 inches:

[tex] P = 2W + 2L = 84 in [/tex]   (2)

By entering equation (1) into equation (2) we have:

[tex]2(\frac{1}{2}L) + 2L = 84 in[/tex]

[tex] L = \frac{84}{3} = 28 in [/tex]

Therefore, the length of the rectangle is 28 inches.

I hope it helps you!  

Answer:

a) 625,000

b) 78,125 if 0 is counted as even or 40,000 if it is not.

Step-by-step explanation:

Represent the 7 digit number by abcdefg

Position          Allowable digits          Number of allowable digits

g                      1,3,5,7,9                          5

f                       0,1,2,3,4,5,6,7,8,9          10

e                      1,3,5,7,9                          5

d                      0,1,2,3,4,5,6,7,8,9          10

c                      1,3,5,7,9                          5

b                       0,1,2,3,4,5,6,7,8,9         10

a                      1,3,5,7,9                          5

This implies that the number of 7 digit numbers with odd digits in the odd positions is

5x10x5x10x5x10x5=625000  

For part b, count 0 as an even digit.  Then rule out 1,3,5,7,9 in positions b, d, and f. This leaves 5 possible digits in all 7 locations. So the answer is

5^7=78,125    

If 0 is not counted as an even digit, then the answer is

4^3+5^4=40000

Answer:

Refer to explanation..

Step-by-step explanation:

Since x represent same number when if it is used multiple times..

40 - 3 - 3 = 34 (Find out how many is 4 x)

4x = 34

X = 34 ÷ 4 = 8.5

I don't know what the question is finding for, if it's breadth then it's 8.5, if it is finding length..

Length = 8.5 + 3 = 11.5
