Answer:

4.75 inches

Step-by-step explanation:

9.5 ÷ 2 = 4.75

1/2 + 3/8 = 4+3/8 = 7/8

Answer:

7 / 8

Step-by-step explanation:

In order to add fractions, the denominators must be the same.

1 / 2 + 3 / 8

Find the least common denominator by prime factorization.

2:2

8:2, 2, 2

To determine the least common denominator (LCD), multiply the common factor 2 times the other factors in blue.

LCD = 2 × 2 × 2 = 8

Multiply  1 / 2 times 4 / 4 so that it will have a denominator of 8.

1 / 2 × 4 / 4 + 3 / 8

= 4 / 8 + 3 / 8

= 7 / 8

Hope this helps :)

Answer:

4 /19

Step-by-step explanation:

3(7x - 1) = 1(2x + 1)

21x - 3 = 2x + 1

19x = 4

x  4/19

Answer:

16,777,216 bacterias.

Step-by-step explanation:

There are 24 hours in one day, and the given bacteria (1) doubles every hour.

Hour 0: 1

Hour 1: 1 x 2 = 2

Hour 2: 2 x 2 = 4

Hour 3: 4 x 2 = 8

Hour 4: 8 x 2  = 16

Hour 5: 16 x 2 = 32

Hour 6: 32 x 2 = 64

Hour 7: 64 x 2 = 128

Hour 8: 128 x 2 = 256

Hour 9: 256 x 2 = 512

Hour 10: 512 x 2 = 1,024

Hour 11: 1,024 x 2 = 2,048

Hour 12: 2,048 x 2 = 4,096

Hour 13: 4,096 x 2 = 8,192

Hour 14: 8,192 x 2 = 16,384

Hour 15: 16,384 x 2 = 32,768

Hour 16: 32,768 x 2 = 65,536

Hour 17: 65,536 x 2 = 131,072

Hour 18: 131,072 x 2 = 262,144

Hour 19: 262,144 x 2 = 524,288

Hour 20: 524,288 x 2 = 1,048,576

Hour 21: 1,048,576 x 2 = 2,097,152

Hour 22: 2,097,152 x 2 = 4,194,304

Hour 23: 4,194,304 x 2 = 8,388,608

Hour 24: 8,388,608 x 2 = 16,777,216

~

Another way to do it is using exponential functions. If it doubles every hour as such: [tex]2^{x}[/tex]  , in which x is the amount of hours: [tex]2^{24} = 16777216[/tex]

Answer:

The answer is 13.

Step-by-step explanation:

Answer:

see in the pic, we have: E(-5; -3), F(-3; -6), A(-5; -8), B(1,-8), C(3; -5), D(1;0)

=> AB = 6

[tex]bc = \sqrt{(3 - 1) {}^{2} + ( - 5 + 8) {}^{2} } = \sqrt{13} \\ \\ \\ cd = \sqrt{(1 - 3) {}^{2} + ( - 5) {}^{2} } = \sqrt{29} \\ \\ \\ [/tex]

[tex]de = \sqrt{( - 5 - 1) {}^{2} + ( - 3) {}^{2} } = 3 \sqrt{5} [/tex]

[tex]ef = \sqrt{( - 3 + 5) {}^{2} + ( - 6 + 3) {}^{2} } = \sqrt{13} [/tex]

[tex]fa = \sqrt{( - 5 + 3) {}^{2} + ( - 8 + 6) {}^{2} } = 2 \sqrt{2} [/tex]

the perimeter of the shape = AB + BC + CD + DE + EF + FA

[tex] = 6 + \sqrt{13} + \sqrt{29} +3 \sqrt{5} + \sqrt{13} + 2 \sqrt{2} [/tex]

[tex] = 28.13[/tex]

Answer:

The only prime numbers between 60 and 70 are 61 and 67 -->

Step-by-step explanation:

Don't get confused by the words and write it out!

What is [tex]\frac{8\sqrt{3}}{2}[/tex]?

we can seperate this to what is 8 * [tex]\sqrt{3}[/tex] / 2

we just cancel out the 2 with the 8. So the answer will be

4[tex]\sqrt3[/tex]

Answer:   c

Step-by-step explanation:

men- 24

women- 28

for every 6 men there are 7 women on the plane bc 28/24= 1.16

1.16 x 6=7 women

The coordinates of the point that makes the division in the given ratio is (0,3)

Step-by-step explanation:

Here, we want to find the point on the line segment that divides the line segment in the ratio 1:2

We simply use the internal division formula

That would be;

(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)

m = 1 and n = 2

(x1,y1) = (4,9)

(x2,y2) = (-8,-9)

Substituting these values into the formula, we have;

2(4) + 1(-8)/(1 + 2) , 2(9) + 1(-9)/(2 + 1)

= (8-8)/3 , (18-9)/3

= (0,3)

Answer:

An equation could be 2-4= -2

Step-by-step explanation:

You would count down 4 times from the the number 2 (below the line that says 3) then your answer would be  -2 since below it, is -3. Obviously the number obove it would be 2.

Step-by-step explanation:

Given

8(x - 1) = - 4x + 136

8x - 8 = -4x + 136

8x + 4x = 136 + 8

12x = 144

x = 144 / 12

x = 12

Answer:

$ 9.5 per person

Step-by-step explanation:

If it is $ 95 for 10 people then to find the unit rate per person is to just divide the total amount by the total number of people.

i.e, 95 / 10 = $ 9.5
