The school band is selling items to raise $9,500 for a trip. For each item sold, the band's profit is a percent of the sellin

Finger [1]

The goal amount of the student groups are given in percentages, which are fractions based on one hundred.

The flutist raised more money than the trumpeters

The difference in the amounts the student raised is $256.5

Reasons:

The amount the school band is raising for the trip = $9,500

Goal of the flutist = To raise 18% of the total amount

Goal of the trumpeters = 85% of the flutist's goal

Required:

The group that raise more money, given that their goals are met

Solution:

Given that the goal of the trumpeters trumpeters is 85% of the goal of the flutist, the flutist raised more money.

Required:

The difference in the amount raised by the students

Solution:

The amount raised by the flutist = 18% of $9,500 = 0.18 × $9,500 = $1,710

Amount the trumpeters raised = 85% of $1,710 = 0.85 × $1,710 = $1,453.5

The difference in the amount raised = $1,710 - $1,453.5 = $256.5

Could someone help me with this

Pavel [41]

Answer:

y = 5

x = 10

Step-by-step explanation:

Remember your 30 60 90 triangle rules.

The 5√3 would equal x√3, so x would equal 5.

The x for the hypotenuse is 2x, so 2(5) is 10.

The y is the x for a 30 60 90 triangle, so y = 5.

In aâ€‹ lottery, 6 numbers are randomly sampled without replacement from the integers 1 to 50. Their order of selection is not i

nlexa [21]

Answer: 0.444225

Step-by-step explanation:

Given : The total number of tickets = 50

Number of tickets are randomly sampled without replacement =6

Since the order of selection is not important , so we use combinations.

Total number of ways to select 6 tickets = $^{50}C_6$

The number of winning tickets = 6

So, number of tickets that are not winning = 50-6=44

Number of ways of selecting zero winning numbers= $^{44}C_{6}$

Now , the probability of holding a ticket that has zero winning numbers out of the 6 numbers selected for the winning ticket out of the 50 possible numbers would be $\dfrac{^{44}C_{6}}{^{50}C_6}$

$=\dfrac{\dfrac{44!}{6!(44-6)!}}{\dfrac{50!}{6!(50-6)!}}\\\\\\=\dfrac{\dfrac{44\times43\times42\times41\times40\times39\times38!}{38!}}{\dfrac{50\times49\times48\times47\times46\times45\times44!}{44!}}\\\\\\=\dfrac{44\times43\times42\times41\times40\times39}{50\times49\times48\times47\times46\times45}\\\\=\dfrac{252109}{567525}\approx0.444225$

Hence, the required probability = 0.444225

In a toy store, the ratio of the number of dolls to the number of teddy bears is . If the store has 240 dolls, how many teddy

forsale [732]

Answer:

So, the way a ratio works is "for every 1 of this, we have 4 of this" for example. (the ratio I just described would be 1:4.)

I believe I've seen this question before. If the ratio of dolls to teddy bears is 9:3 then for every 9 dolls you have 3 teddy bears.

So, since we have 240 dolls and a 9:3 ratio to teddy bears, all we have to do is take how many dolls we have (240) and divide it by 3 to see how many teddy bears we have.

So:

240 ÷ 3 = 80

If your ratio is 9:3, then 80 is your answer.

Hope this helps and have a nice day!
