3/8 plus 5/6 divided by 5 A. 4 13/25 B.3/14 C.13/24 D.2 3/8 HELP NOW !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

Step-by-step explanation:

Try working this out with decimals

3/8 = 0.375

5/6 = 0.833     Add these

Total = 1.20833

Now divide by 5

1.20833/5

.24166

I think I would use this as my answer, but if you want fractions ...

3/8 + 5/6      The common denominator is 24

3*3/3*8 = 9 / 24

5*4/6*4 = 20/24

9/24 + 20/24 = 29/24

Now divide by 5

==================

29 / 24 // 5/1                      Invert the denominator and multiply

29/24 * 1/5 = 29/120      

Does that equal the decimal result that we got?

29/120 = .24166 which is the same thing. The fractions are a little harder to handle than the decimals.

A store sells toys in bulk. It sells wooden blocks for $5 a pound and plastic bricks for $10 a pound. How many pounds of wooden blocks and plastic bricks should be used to make a 10-pound mixture that would sell for $80?

Answers

Answer: 4 pounds of wooden blocks and 6 pounds of plastic bricks should be used.

Step-by-step explanation:

Let x = Quantity of wooden blocks.

y = Quantity of plastic bricks.

As per given , we ahve

5x+10y=80        (i)

x+y=10     (ii)

Multiply 5 on both sides of (ii), we get

5x+5y=50   (iii)

Eliminate (i) from (iii), we get

5y=30

⇒ y= 6

Put y=6 in (ii), we get

x+6=10

⇒ x= 10-6= 4

Hence, 4 pounds of wooden blocks and 6 pounds of plastic bricks should be used.

Answer:   A. 50

===============================================

Explanation:

The order of the lettering is important when it comes to similar polygons. This is because the order tells us how the letters pair up.

I don't recommend using solely the diagram to try to see how the angles pair up because the diagram might not be to scale. So we'll just be focused on the lettering.

In the sequences ABCDE and PQRST, we have letters E and T as the last items. This means they correspond and pair up together. Furthermore, these angles are congruent (since similar polygons have congruent corresponding angles).

So in short, E = T.

The diagram shows E = 110 and T = 2x+10

This leads to...

E = T

110 = 2x+10

2x+10 = 110

2x = 110-10

2x = 100

x = 100/2

x = 50

How many 3 2/3 ounce bottles of perfume can be filled from a jug containing 64 ounces?

Answers

Answer:

24 bottles would fill the jug

Step-by-step explanation:

Given

[tex]Bottles = 3\frac{2}{3}[/tex]

[tex]Jug = 64[/tex]

Required

Determine the number of bottles in a jug.

To do this, we simply divide the given measurements of jug and the bottle.

In other words,

[tex]Number = \frac{Jug}{Bottle}[/tex]

[tex]Number = \frac{64}{3\frac{2}{3}}[/tex]

Convert fraction to improper

[tex]Number = \frac{64}{\frac{8}{3}}[/tex]

[tex]Number = 64/\frac{8}{3}[/tex]

[tex]Number = 64*\frac{3}{8}[/tex]

[tex]Number = 8 * 3[/tex]

[tex]Number = 24[/tex]

Hence, 24 bottles would fill the jug

Given the system of equations, solve for x
2x - 3y = -19
4x + 5y = 17

Answers

Answer:x=-2

Step-by-step explanation: First, you need to multiply 2 for the first equation. The first equation becomes 4x-6y=-38. Then you have to subtract the first equation from the second equation, so it becomes 11y=55. 55/11=5, so y =5. We can plug 5 into the equation, and from there, we can draw out the conclusion that x=-2. You can also verify this by plugging -2 into the equation, which I did.

The manager of an ice cream shop found that the probability of a new customer ordering vanilla ice is 7\9. What are the odds against a new customer ordering vanilla ice cream?

Answers

Answer:

The odds-against a new customer ordering a vanilla ice cream are: 2/7 or 2 to 7

Step-by-step explanation:

Odds-against is the ratio of probability of non-occurrence of an event to the probability of occurrence of an event.

Let p be the probability that the new customer will order vanilla

Then

[tex]p = \frac{7}{9}[/tex]

Let q be the probability that the new customer will not order vanilla

[tex]q = 1-p\\= 1 - \frac{7}{9}\\= \frac{9-7}{9}\\=\frac{2}{9}[/tex]

Now the odds against formula is:

[tex]\frac{Probability\ of\ non-occurrence}{Probability\ of\ occurrence}= \frac{q}{p}\\=\frac{\frac{2}{9}}{\frac{7}{9}}\\=\frac{2}{9} * \frac{9}{7}\\=\frac{2}{7}[/tex]

Hence,

The odds-against a new customer ordering a vanilla ice cream are: 2/7 or 2 to 7

If 10% of men are bald, what is the probability that fewer than 100 in a random sample of 818 men are bald? (Answers must be in 4 decimal values)

Answers

Answer: the probability that fewer than 100 in a random sample of 818 men are bald is 0.9830

Step-by-step explanation:

Given that;

p = 10% = 0.1

so let q = 1 - p = 1 - 0.1 = 0.9

n = 818

μ = np = 818 × 0.1 = 81.8

α = √(npq) = √( 818 × 0.1 × 0.9 ) = √73.62 = 8.58

Now to find P( x < 100)

we say;

Z = (X-μ / α) = ((100-81.8) / 8.58) = 18.2 / 8.58 = 2.12

P(x<100) = P(z < 2.12)

from z-score table

P(z < 2.12) = 0.9830

Therefore the probability that fewer than 100 in a random sample of 818 men are bald is 0.9830
