Mekala Jumble has 4 techno songs, 2 country songs, and3 jazz songs on it.

Ratio of techno songs,to country songs,to jazz songs= 4: 2 : 3

Whatever be total  number of songs, let the number of techno songs, country songs,and jazz songs be  4 x,  2 x, and  3 x.

Total number of songs that Mekala plans to Listen = 2 70

Then , 4 x + 2 x + 3 x= 270

9 x = 270

Dividing both sides by 9, we get

x = 30

So, Number of techno songs = 4 × 30= 120

Number of techno songs = 2 × 30= 60

Number of jazz songs = 3 × 30= 90

Option (b) b) Close to 60 country songs but probably not exactly 60 country songs  ,is true option regarding number of songs listen by Mekala.

Nicholas scoops a few gum balls into his bag when he weighs it he finds that he scooped 0.76 pounds how much will the gum balls
11111nata11111 [884]

Answer:

The cost of 0.76 pound gum ball is $2.6448

The cost of 1.5 pounds of sour patch kids is $5.985

Step-by-step explanation:

Consider the provided information.

Nicholas scoops a few gum balls into his bag when he weighs it he finds that he scooped 0.76 pounds. The cost of 1 pound of gum balls is $3.48

This can be written as:

1 pound gum ball= $3.48

Multiply both the sides by 0.76

1×0.76 pound gum ball= $3.48×0.76

0.76 pound gum ball= $2.6448

Hence, the cost of 0.76 pound gum ball is $2.6448

Nichols has decided to buy 1.5 pounds of sour patch kids and the cost of 1 pound of sour patch kids is $3.99

This can be written as:

1 pound sour patch kids = $3.99

Multiply both the sides by 1.5

1×1.5 pound sour patch kids = $3.99×1.5

1.5 pound sour patch kids = $5.985

Hence, the cost of 1.5 pounds of sour patch kids is $5.985

Beth normally cycles a total distance of 56 miles per week.
Vikki [24]

Answer:

She will cycle 85.169 miles in the third week.

(round if needed)

Step-by-step explanation:

56÷100=0.56 (this is 1%)

0.56 x 15 + 56 = 64.4 (you find 15% then add 56 (the original amount) because it's an increase of 15%)

repeat for the other 3 weeks

64.4÷100=0.644

0.644 x 15 + 64.4 = 74.06

74.06÷100=0.7406

0.7406 x 15 + 74.06 = 85.169

Mark has a 25 ounce drink. He drinks 5 ounces. What percent of the drink does he have left?
valina [46]

Answer: 80\%

Step-by-step explanation:

This problem can be solved by the <u>Rule of Three</u>, which is a mathematical rule to find out an amount that is with another quantity given in the same relation as other two also known.

In this case, the 25 ounce drink represents the 100 \% . So, if Mark drinks 5 ounces, this means he has 20 ounces left and we have to find the percent this represents:

25 oz ------- 100\%

20 oz -------- ?

?=\frac{(20 oz)(100\%)}{25 oz}

?=80\% This is the percent of the drink Mark has left

Suppose the distributor charges the artist a $40.00 cost for distribution, and the streaming services pays $4.00 per unit. (Note
denpristay [2]

Given :

Suppose the distributor charges the artist a $40.00 cost for distribution, and the streaming services pays $4.00 per unit

Step-by-step explanation:  

Cost of distribution is the fixed cost . y intercept is the fixed cost.

Distributor charge is 40. So y intercept = 40

Payment per unit is the slope that is 4 per unit.

slope =4

Slope intercept form is y=mx+b

Where m is the slope and b is the y intercept.

y intercept b=40. and slope m=4

So the equation of the line is y=4x+40

The graph of the line is included below

To find the number of streams that pay for distributor charges , we set

the equation equal to 0 and solve for x

4x+40=0\\4x=-40\\divide   by 4\\x=-10

10 streams you pay for distributor charges.

Given profit is 750,000. so y=750,000

We need to find out x the number of streams

y=4x+40\\750000=4x+40\\\\Subtract 40\\divide 4\\x=187,490

we know that 1 unit = one thousand streams

so , Approximately 187 streams

Answer:

y intercept = 40

slope =4

y=4x+40

10 streams you pay for distributor charges.

187 streams to get  profit $750,000
