Riverside Elementary School is holding a school-wide election to choose a school color. Five-eighths of the votes were for blue,

Mnenie [13.5K]

Answer:

Step-by-step explanation:

Let the total number of votes to choose a color = x

Number of votes for blue = $\frac{5}{8}\times x$

Remaining votes = x - $\frac{5}{8}\times x$

= $\frac{8x-5x}{8}\times x$

= $\frac{3}{8}\times x$

Votes for green = $\frac{5}{9}\times (\text{Remaining votes})}$

= $\frac{5}{9}\times \frac{3x}{8}$

= $\frac{5}{24}\times x$

Finally remaining votes = $\frac{3x}{8}-\frac{5x}{24}$

= $\frac{9x-5x}{24}$

= $\frac{4x}{24}$

= $\frac{x}{6}$

Since these votes are for red therefore,

$\frac{x}{6}$ = 48

x = 48×6

= 288

a) Votes for blue are $\frac{5x}{8}$

Therefore, exact number for blue votes = $\frac{5\times 288}{8}$

= 5×36

= 180

b). Votes for green = $\frac{5x}{24}$

= $\frac{5\times 288}{24}$

= 60

c). Since 25 students were absent on that day of the vote, number of students at Riverside Elementary School = 288 + 25

= 313

d). Since seven tenths of the votes for blue were made by the girls.

Therefore, number of girls voted for blue = $\frac{7}{10}\times 180$

= 7×18

= 126

Since total votes made = 288

Therefore, half of the votes made = $\frac{288}{2}$

= 144

Now it's clear that number of votes made by girls is less than half of all the votes.

e). 126 girls voted for blue.

(20 points) A 2-liter bottle of soda (67.6 ounces) costs $1.89. A case of twelve 12 ounce

horrorfan [7]

Answer:

Unit price of a 2-liter bottle of soda: $\$0.028\ per\ ounce$
Unit price of a case of twelve 12 ounce cans: $\$0.021\ per\ ounce$
The better bargain is the case of 12 ounce cans.

Step-by-step explanation:

Let be "x" the unit price (price/ounce) of the soda in the 2-liter bottle and "y" the unit price (price/ounce) of the soda in the case of twelve 12 ounces cans.

According to the data provided in the exercise, you know that:

1. The 2-liter bottle of soda is equal to 67.6 ounces.

2. That bottle costs $1.89

Then, the unit price is:

$x=\frac{1.89}{67.6}\\\\x\approx0.028$

3. There are 12 ounce cans in the case. Then the total ounces is:

$12\ oz*12=144\ oz$

4. It costs $2.99. So the unit price is:

$y=\frac{2.99}{144}\\\\y\approx0.021$

Since:

$y$

The better bargain is the case of 12 ounce cans.

Evan claims that if he multiplies 1,458,362,287 Buy two that the answer will be an even number without doing the multiplication

dsp73

With multiplication, there are a few handy rules to remember:

If you multiply an even and an even, the answer will be even!
If you multiply an odd and an odd, the answer will be odd!
If you multiply an even and an odd, the answer will be even!

Knowing this, if we go back and look at the numbers Evan is trying to multiply, we can try to use these rules!

The last number of that really big number is a 7, which is odd, and the number 2 is even, and because we know that an odd number times an even number is an even number, Evan will be right!
