Marissa collects donations for a dance marathon. One group of sponsors will donate a total of $25 for each hour she dances. Another group of sponsors will make a one-time donation of $100 regardless of how long she dances. What number of hours should she dance if she wishes to raise at least $500?

Answers

Answer:

20 hours

Step-by-step explanation:

25x20=500

The one time donation will not fufill the needs, but the payment each hour will help Marissa reach her donation goal.

One group giving $100 regardless how long but one donating $25 per hour. So $100+25(hours)= 500 to find the solution since they need $500 deduct $100 then it’s 400 divided by 25 which is 16 hours so

$100+25(16)=500 hours. So 16 hours

Part C
What percentage of those surveyed have both a snake and a lizard?

Answers

Percentage of people having Lizard = 55% , Percentage of people having both Lizard & Snake = 10%

Important Information : Percentage people having pet snake = 40%

C] Percentage people having pet lizard, along with pet snake = 25% of those having pet snake = 25% of 40% = 10% {Percentage of people having both snake & lizard)

Percentage of people having pet snake only = 75% of those who don't have snake = 75% of ( total - 40%) = 75% of 60% = 45%

B] Total percentage of people having pet lizard = 10% + 45% = 55%

Hey there!

In order to solve for this particular question that you have asked.. we can just simply divide 28 from 4

Equation: 28 / 4

28 ÷ 4 / 4 ÷ 4

28 ÷ 4 = 7

4 ÷ 4 = 1

New equation: 7 / 1

Answer:

It would be relation B and f (x)

Step-by-step explanation:

for it to be a function X (-8) can only have one outcome, however that isn't the case with A.

and I believe if I'm remembering correctly, one-to-one correspondence is each element of one set is only paired with one element of the other set which isn't true for B, so it should be f (x), though you may want to look it up for yourself to make sure.

Find the value of n.

(-y + 5.3) + (7.2y - 9) = 6.2y + n

Transfer 6.2y to the other side and change its sign.

(-y + 5.3) + (7.2y - 9) - 6.2y = n

Solve for the value of n.

-y + 5.3 + 7.2y - 9 - 6.2y = n

group like terms

-y + 7.2y - 6.2y + 5.3 - 9 = n

0 + (-3.7) = n

-3.7 = n

Substitute n with its value.

(-y + 5.3) + (7.2y - 9) = 6.2y + n

(-y + 5.3) + (7.2y - 9) = 6.2y + (-3.7)

-y + 5.3 + 7.2y - 9 = 6.2y - 3.7

Group like terms

-y + 7.2y + 5.3 - 9 = 6.2y - 3.7

6.2y - 3.7 = 6.2y - 3.7

Hope this helped! :D
it’s 6x + 19
because you do 6(x + 2) u multiply the 6 times the x which is 6x and then 6 x 2 which is 12 so ur equation would be 6x + 12 + 7 so you just add 12 and 7 which is 19
