Which shows the expression below in simplified form?

(5 × 105) × (6 × 10-2)

Answer:

50 people

Step-by-step explanation:

so to solve this we can use cross multiplying:

first we know that 20% = 10 people and 80% = x people (we put x because we don't know how many people)

then we set it up:

[tex]\frac{10}{20}[/tex] = [tex]\frac{x}{80}[/tex]

= 20x = 800

= x = 40

now it asks how many people were surveyed in total so we add the 10 + 40 = 50

50 people were surveyed

Answer:

yes they both form a proportion

Answer:

1) x + 4 = 11

Subtract 4 on both sides, to get x = 7 .

2) x + 3 = 24

Subtract 3 on both sides, to get x = 21 .

3) 4x = 12

Divide 4 on both sides, to get x = 3 .

4) 5x + 3 = 33

First subtract 3 on both sides to get

5x = 30, now divide 5 on both sides, to

get x = 6 .

5) 8x + 5 = 3x + 20

First subtract 5 from 20 in order to

move it, now you have 8x = 3x + 15 .

Next subtract 3x from 8x in order to

move it, now you have 5x = 15 . Lastly

divide 5 on both sides, to get x = 3 .

1) 1/2 x = 4

Multiply both sides by 2, to get 1x = 8,

or x = 8 .

2) 4/3 x = 4

Multiply both sides by 3, to get 4x = 12 .

Next divide 4 on both sides to get

x = 3 .

3) 2x + (-4) = 8

Add 4 on both sides, to get 2x = 12 .

Next divide 2 on both sides to get

x = 6 .

4) 1/3 x + 1/2 x = 20

First multiply the denominators to get a

common denominator of 6 and then

add 3 and 2, to get the numerator. Now

you have 5/6 x = 20 . Next multiply 6

on both sides to get 5x = 120 . Lastly

divide 5 on both sides to get x = 24 .

5) 1/3 x = 1/5 x + 10

First multiply the denominator to get a

common denominator of 15 and then

subtract 3 from 5 to get the numerator.

Now you have 2/15 x = 10 . Next

multiply 15 on both sides to get

2x = 150. Lastly divide 2 on both sides

to get x = 75 .

Hope this helped :)

Your answer is : $2.09

To find this answer you first need to find out how much money Dani spend.The equation for this is (5.72+4.89+7.30=17.91).The last step is to subtract the amount Dani spent by the amount she paid so new equation is (20.00-17.91=2.09)The answer is $2.09

Step-by-step explanation:

by similarity of triangles TYU and OYL we have

[tex]x + 2 = 2(2x - 14) = 4x - 28 \\ 3x = 28 + 2 = 30 \\ x = 10[/tex]

then

TU=6, OL=12

Answer:

h(5) = 20

Step-by-step explanation:

Assume that '2' is an exponent.

So the question for you should be:-

[tex] \displaystyle \large{h(x) = {x}^{2} - x}[/tex]

We want to find h(5); we substitute x = 5 in.

[tex] \displaystyle \large{h(x) = {5}^{2} - 5}[/tex]

5^2 is 5•5 = 25.

[tex] \displaystyle \large{h(x) = 25 - 5} \\ \displaystyle \large{h(x) = 20}[/tex]

Therefore, h(5) is 20.

x=25 because 30+25=55. and 55-25=30

Answer:

What is the length of an arc cut off?

If θ (in radians) is a central angle in a circle with radius r, then the length of the arc cut off by θ is given by s = r θ (θ is in radians).

Step-by-step explanation:

Length of an Arc = θ × r, where θ is in radian.

Length of an Arc = θ × (π/180) × r, where θ is in degree.

Answer:

r  =  s /2  -  3 x /2

or

x  =  s /3  −  2 r/ 3

Step-by-step explanation:

Answer:

2r+3x=5

2r+3x+-3=5+-3x

2r=5-3x

2r/2=5-3x

2r/2=5-3x/2

r=1/2⁵ + -3/2x

r=1/2⁵ + -3/2x
