A jar contains nickels and dimes. There is a total of 25 coins in the jar. The value of the coins is $1.75. How many nickels and how many dimes are in the jar?

Answers

Answer 1

Answer:

15 nickels and 10 dimes

Step-by-step explanation:

Dimes - d,     dime = 10c,  total dimes = 10dNickels - n,   nickel = 5 c,  total nickels = 5n$1.75 = 175 c

Equations:

d + n = 2510d + 5n = 175

Multiply the first equation by 5 and subtract from the second one:

10d + 5n - 5d - 5n = 175 - 1255d = 50d = 10

Find n:

n = 25 - d = 25 - 10 = 15

Bella can run a mile in 9.54 minutes. Linda can run a mile in 8.22 minutes. How much faster can Linda run than Bella? Justify your reasoning.

Answers

Answer:1.16 times

Step-by-step explanation:

Given

Bella can run a mile in 9.54 minutes

Linda can run a mile in 8.22 minutes

We know, [tex]\text{distance=speed}\times\text{ time}[/tex]

Speed of Bella, for running a mile is

[tex]\Rightarrow v_b=\dfrac{1}{\frac{9.54}{60}}=\dfrac{60}{9.54}\\\\\Rightarrow v_b=6.29\ mph[/tex]

Speed of Linda, for running a mile is

[tex]\Rightarrow v_l=\dfrac{1}{\frac{8.22}{60}}=\dfrac{60}{8.22}\\\\\Rightarrow v_l=7.29\ mph[/tex]

So, Linda is faster than Bella, as her speed is more compared to Linda.

Linda is  [tex]\frac{9.54}{8.22}=1.16[/tex]  times faster than bella

The initial depth of groundwater being held by a storage tank which extends downward below the ground surface is - 25. The rate of change in depth the groundwater per unit of Rainfall is 12. Hence, a linear model which could model the depth of water in the tank in the described scenario is ;

y = 12x − 25

The rate of change in depth of ground water, y per unit change in number of Rainfall, x gives the slope Coefficient, which equals 12

The intercept value, which is the initial depth of groundwater before, it started raining is - 25

Rebecca has been planting young trees in her garden. The maple tree that is 10 centimeters tall
is growing 2 centimeters per month, whereas the oak tree that is 15 centimeters tall is
growing 1 centimeter per month. In a few months, the two trees will be the same height. How
many months will this take and what will that height be?

Answers

Answer:

It will take 5 months and that height will be 20cm.

Step-by-step explanation:

Let the height of the tree be h cm and the number of months be m.

Maple tree

Initial height= 10cm

Total height= 10cm +2(number of months)

h= 2m +10 -----(1)

Oak tree

Initial height= 15cm

Total height= 15cm +1(number of months)

h= m +15 -----(2)

When the height of the two trees are the same,

2m +10= m +15

Solve for m:

2m -m= 15 -10

m= 5

Substitute m=5 into either equation 1 or 2 to obtain the height.

When m=5,

h= 5 +15

h= 20

Read the novel excerpt.Superhero 101: A Family SecretTrace knew he would have to try to explain to his grandmother why he had missed her birthday party. He was dreading the conversation and the lie that he would inevitably have to tell. He thought telling her the truth would only open a Pandoras box. He rang the doorbell, and his grandmother answered right away, like she had been waiting for him. He had called and told her he would try to come by sometime that day, but he had not given her a precise time.She greeted him warmly, and he followed her into the kitchen where she had her customary jar of fresh-baked cookies ready for his indulgence. His grandmother was endearingly predictable. She had a daily routine and rarely deviated from it. Trace thought that given her lifestyle and penchant for routine and order, there was no way she would ever understand his life as Beetleman. He hated that he had no choice but to lie to his grandmother, whom he loved so much.They sat at the kitchen table. His grandmother poured him an ice-cold glass of milk and filled a plate with her delicious chocolate chip cookies. Before he had a chance to apologize, his grandmother spoke. Trace, Im glad you called and came by today. I know youre upset about missing my birthday party, but before you say anything about it, there is something I want to show you, she said.She went to a drawer and retrieved what appeared to be a large bracelet cuff made of silver. She handed it to Trace. He looked at it carefully. His grandmother moved his hands and pointed to something inscribed on the inside of the bracelet. Look at this. It's what I wanted you to see, she said as Trace read the words Family First. His heart sank when he read those words and recounted all the times that he had to sacrifice time with his family for his secret life.His grandmother noticed his dejected expression. Trace, I didnt show you this to make you feel bad about your choices. I know that they arent always yours to make. This cuff belonged to your grandfather. He had those words inscribed because they are what kept him going and allowed him to make those same tough choices.Trace stared at this grandmother. What was she saying? His grandfather was a superhero too?She continued, Your grandfather loved helping people, just like you do. Thats where you got your giftfrom him. Many times he had to miss family parties and outings because of his calling. But I always knew he did it for usfamily first.Trace was astounded. Hed had no idea that his grandfather was a superhero; now he realized that he no longer had to lie to his grandmother. His parents had died when he was very young, and his grandparents had raised him. He recalled his grandfather missing his 10th birthday party and how upset and angry he had been at his grandfather. He had cried himself to sleep that night, wrongly thinking that he was not important to his grandfather.Trace looked at the bracelet carefully, realizing that to him, it was as precious as the Hope diamond. He glanced up at his grandmother. His love for his family was his kryptonite, his grandmother continued. The only time he was weak was when you or I were in danger. He couldnt bear the thought of anything happening to us after what happened to your parents.In Superhero 101: A Family Secret, Trace misses his grandmothers birthday party and visits her to apologize.How does this incident provoke Trace to make a decision?He doesn't want to admit that he missed the party on purpose.It forces him to admit his anger at his grandfather.He wants a reason to ask about his parents.It forces him to lie to his grandmother to conceal who he really is. which of these is closest to the number of molecules of ATP we get from Anaerobic metabolism of one molecule of glucose? -2 -6 -10 -32 -48 Which word or phrase is the best one to use to communicate to yourgrandmother that your cat is not friendly to people?A.
