Twenty-two percent of the seventh-grade class at Santa Ana Middle School has blue eyes. If the seventh-grade class has 139 students, about how many have blue eyes?

Answer:

11.5

Step-by-step explanation:

Divide: 159:6-15

Calculate: 26.5-15

\\11.5//

Answer:

24.8333 with 3 repeating.

Step-by-step explanation:

Lets make an equation for this.

159 - x = 15

X is what we are loooking for so lets isolate it.

Subtract 159 on both sides.

-x = -149

Since both are negative we need to simply cross it out.

x = 149

Now he bought six books, so divide 149 by 6.

You would get 24.8333 with the 3 repeating.

Answer:

Step-by-step explanation:

2 2/5 is equal to 12/5 because...

1 2/5 = 7/5

2 2/5 = 12/5

You add five to the numerator for each 1 you get in the mixed number.

Answer:

22g+6

Step-by-step explanation:

-3(-4g-6g-2)-8g  To simplify this, we have to distribute first.

12g+18g+6-8g    Now, we can combine like terms. (I underlined the parts with the variable to make it easier to see which parts were considered like terms.)

22g+6                 This is your simplified answer!!

Hope this helps...have a wonderful day c:

Answer:

y= -x+6

Step-by-step explanation:

The equation format for slope-intercept form is y=mx+c, where m is the slope of the line and c is the y-intercept.

To find the slope, we need to pick two definite points and find the slope from that. The formula to find the slope is 'rise/run'. Rise is the difference between the y-values of the two points, and the run is the difference between the x-values of the two points.

Let's use the points (0,6) and (1,5).

The rise is -1 (5-6=-1) and the run is also 1 (1-0=1). This means that the slope is -1 (-1/1=-1). The slope is negative because the line is 'going downwards'.

So our equation so far is:

y=-x+c

The y-intercept is where the line crosses the y-axis and the x-value is 0. We can see from the graph that the line crosses the y-axis at the point (0,6), therefore the y-intercept is 6.

So our final equation for the line is y= -x+6.

Answer:

1.) 15-3-2=x

2.) He can buy 3 sodas

Step-by-step explanation:

1.) 15 is how much he has, -3 is the price of the popcorn, -2is the price of the soda. =x is what needs to be solved in the equation (its 10 if you need the answer)

2.) He can buy 3 sodas because 3 boxes of popcorn is $9 since one box is $3,  he has $15 you take away $9 and you are left with $6 and 6 divided by 2 is 3.

Answer:

1. ) $6,734.30

2) 12 years

Step-by-step explanation:

1. we use the compound interest formula for this

Mathematically;

A = P( 1 + r/n)^nt

where P is the principal which is the amount deposited = $5,000

r = rate = 6% = 6/100 = 0.06

n = number of time per year we compound = 4 since it is quarterly

t = number of years = 5

Substituting all of these, we have;

A = 5,000( 1 + 0.06/4)^(4)(5)

A = 5,000( 1 + 0.015)^20

A = 5,000(1.015)^20

A = $6,734.28 which to the nearest cent = $6,734.30

2) For the money to double means that A becomes 2P

Thus;

2P = P( 1 + 0.015)^4t

divide both sides by P

2 = (1.015)^4t

Fine the ln of both sides

ln 2 = 4t ln 1.015

divide both sides by ln 1.015

4t = ln 2/ ln 1.015

4t = 46.56

t = 46.56/4

t = 11.63 which is approximately 12 years

Answer:

The correct answer is 0.25 and if you're looking for fraction form its 1/4.

Step-by-step explanation:

Final Answer:

1/4

Step-by-step explanation:

[tex]\frac{2}{5}[/tex] ÷ [tex]\frac{8}{5}[/tex]

[tex]\frac{2}{5}[/tex] ÷ [tex]\frac{5}{8}[/tex]  (reciprocal method)

[tex]\frac{2}{5}[/tex] × [tex]\frac{5}{8}[/tex] = [tex]\frac{10}{40}[/tex] (changing the operation to multiplication, then multiply the fractions)

[tex]\frac{10}{40}[/tex] ⇒ [tex]\frac{1}{4}[/tex] (reduce the answer)
