In order to multiply fractions, we multiply the two numerators together, and multiply the two denominators together.

$\frac{2}{5}\times \frac{6}{7} =\frac{2\times6}{5\times7} \\\frac{2\times6}{5\times7} =\frac{12}{35}$

12/35 is the answer

Answer:

x = 13

y = 18.38

Step-by-step explanation:

tan 45 = x/13 (tangent = opposite / adjacent)

1 = x/13

multiply both sides by 13

x = 13

cos 45 = 13/y (cosine = adjacent / hypotenuse

0.7071 = 13/y

multiply both side by y

0.7071y = 13

divide both side by 0.7071

y = 18.38

Two percent of Jennies skin cells were burned when she escaped from a fire. If

andreev551 [17]

$1.813*10^{12}$ cells of Jennies skin were not burned.

Step-by-step explanation:

Given,

Burned skin cells = $3.7*10^{10}$

This represents 2% of total skin cells.

Let,

x represents the total number of skin cells.

2% of x = $3.7*10^{10}$

$\frac{2}{100}x=3.7*10^{10}\\\\0.02x=3.7*10^{10}$

Dividing both sides by 0.02

$\frac{0.02x}{0.02}=\frac{3.7*10^{10}}{0.02}\\\\x=1.85*10^{12}$

Number of not burned cells = Total - burned

Number of not burned cells = $1.85*10^{12}-3.7*10^{10}$

Number of not burned cells = $1.813*10^{12}$

$1.813*10^{12}$ cells of Jennies skin were not burned.

What are the answers for 1-4 this is geometry.

elena-s [515]

Answer/Step-by-step explanation:

1. x*21 = 24*14 (intersecting chords theorem)

21x = 336

x = 336/21

x = 16

2. 27*x = 45² (secant-tangent rule)

27x = 2,025

x = 2,025/27

x = 75

3. (x + 5)*5 = (4 + 6)*6 (Intersecting secants theorem)

5x + 25 = (10)*6

5x + 25 = 60

5x = 60 - 25

5x = 35

x = 35/5

x = 7

4. (4x + 2)*8 = (5x + 1)*7

32x + 16 = 35x + 7

Collect like terms

32x - 35x = -16 + 7

-3x = -9

x = -9/-3

x = 3
