A bag contains 4 red marbles, 9 blue marbles, and 7 white marbles. What is the probability of picking neither a blue nor a white marble?

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of single cone ice cream and let y represent the number of double cone ice cream.

Since the vendor stocks a maximum of 70 single cones and a maximum of 45 double cones. hence:

0 < x ≤ 70, 0 < y ≤ 45      (1)

The vendor expects to sell no more than 50 ice creams, hence:

x + y ≤ 50

Plotting the constraint using geogebra online graphing tool, we can see that the solution to the problem is at (5, 45)

Since the vendor sells single-cone ice-creams for $3 and double-cone ice-creams for $4.50, hence:

Revenue = 3x + 4.5y

At the point (5, 45), the revenue is:

Revenue = 3(5) + 4.5(45) = $217.5

Step-by-step explanation:

A. Calculate the amount of money Oliver saves in one week.

This will be:

= 10% × $520

= 1/10 × $520

= 0.1 × $520

= $52

B. There are 52 weeks in one year. If Oliver saves the same amount each week for 6 months, how much will he save?

This will be:

= $52 × 52weeks/2

= $52 × 26

= $1352

Note that 6 months will be:

= 52 weeks/2

= 26 weeks.

Answer:

18.

Step-by-step explanation:

3*12 = 36

36/2 = 18

18*3 = 54

54/3 = 18

Answer:

x2 + 4xy - 4y2

Step-by-step explanation:

You have to subtract the values with like terms, so you´d have to take x2 from 2x2. You can´t take away x2 from 6xy because they are different terms, and it wouldn´t be compatible.

Answer:

18.75=p

s=14.06

b=2.34

Step-by-step explanation:

37.75=b+s+p

-4

33.75=b+s+p

s=3/4p

b=1/6s

33.75=1/6(3/4p)+3/4p+p

33.75=3/20p+3/4p+p

(33.75=18/20p+p)20

675=18p+p)/18

37.50=2p)/2

18.75=p

s=3/4p

3/4(18.75)

s=14.06

b=1/6s

1/6(14.06)

b=2.34

37.75-4=18.75+14.06+2.34=35.15

im missing 50 cents somewhere its wrong but close i think sorry

The cost of a brush, a sketchbook and a paint set given the total amount with Tina is $2.25, $13.5 and $18 respectively.

Total = $37.75

Amount left = $4.00

let

37.75 = p + b + s + 4

37.75 - 4 = p + 1/6s + 3/4p

33.75 = 1/6s + 1 3/4p

33.75 = 1/6(3/4p) + 1 3/4p

33.75 = 3/24p + 7/4p

33.75 = 3+42 / 24p

33.75 = 45/24p

p = 33.75 ÷ 45/24

= 33.75 × 24/45

= 810/45

p = $18

substitute into

s = 3/4p

= 3/4 × 18

= 54/4

s = $13.5

b = 1/6s

b = 1/6 × 13.5

b = 13.5/6

b = $2.25

Answer:

37 degrees

Step-by-step explanation:

1. m∠CBA = 71+45 = 116 degrees

2. m∠CBA = m∠CDA because of the quadrilateral property of opposite sides.

3. m∠CBA + m∠CDA = 2*116 = 232.

4. Total angle measure of a quadrilateral is 360 degrees, so m∠BAD + m∠BCD = 360-232 = 128 degrees.

5. m∠BAD = m∠BCD = 128/2 = 64 degrees

6. m∠BAC = m∠BAD - m∠CAD = 64 - 27 = 37 degrees

Answer:

1.28

Step-by-step explanation:

First, you need to do 82/64, which will give you just x. Then, you need to round to three places. Without rounding it would be 1.28125

So with rounding it would be 1.28. Hope this helps and Happy learning!

Answer: 10 degrees

Step-by-step explanation:

Since it is a right triangle the angle is 90 degrees.

So, 90 degrees -50 degrees is equal to 40 degrees.

40 divided by 4 is 10.

So your answer is 10 degrees.

Answer:

13

Step-by-step explanation:

Angles ( 12x - 29 ) and ( 4x + 1 ) are co - interior angles.

Sum of co - interior angles is supplementary.

12x - 29 + 4x + 1 = 180

12x + 4x - 29 + 1 = 180

16x - 28 = 180

16x = 180 + 28

16x = 208

x = 208 / 16

x = 13

Answer:

5

Step-by-step explanation:

When adding fractions, all you are doing is adding the whole numbers first, 2+2, and then putting that aside. So with 4 on the side, we will then add our fractions. We will line them up and add the numerators and leave the denominator the same. If the numerator is higher than the denominator, we create a whole and subtract the denominator until we are with a smaller numerator. However many times we subtracted this would add a whole number. However, we do not have to do this so we will add 1 and 2 to equal 3. This means we have 3/3 or one whole so we will add 1 to the 4 we had earlier to get 5. Hope this helps :D
