Reese has nickels and dimes in his pocket. He counts a total of 11 coins. The total value of his pocket change is 70 cents. Let 'n' represent the number of nickels and let d represent the number of dimes in Reese’s pocket.
Which equations can be used to represent the information in this problem? Check all that apply.

A) 5n + 10d = 11
B) n + d = 11
C) n + d = 70
D) 5n + 10d = 70
E) 10n + 5d = 70
REMEMBER, THIS IS MULTIPLE CHOICE :)

Answers

The combine equation that represents the information in this problem is as follows;

n + d = 11

5n + 10d = 70

He has only nickel and dimes in his pocket. The total number of coins is 11 coins. The total cost is 70 cents.

let

n = number of nickels in his pocket

d = number of dimes in his pocket

1 nickel = 5 cents

1 dime = 10 cents

Therefore,

Total number of coins:n + d = 11Total cost of the coins5n + 10d = 70

Therefore, the combine equation is as follows:

n + d = 11

5n + 10d = 70

Cora bought half a dozen cupcacks for $2.70. What was the price per cupcakes?

Answers

Answer:

[tex]\approx\$0.23/cupcake[/tex]

Step-by-step explanation:

[tex]\frac{\$2.70}{12cupcakes}=\frac{\$0.225}{1cupcake}\approx\$0.23/cupcake[/tex]

A dozen is 12 so half of that is 6 so.

2.70/6= 0.45

Which is 45 cents

11.50 + 1.15x = 12.65
11.50 - 11.50 + 1.15x = 12.65 - 11.50

➗ 1.15x = 1.15 ➗ what does x equal? Please explain in great detail how you figured this out also replace the = with the proper inequality sign and explain how you did that as well.

Answers

Answer: the answer is x= 1

Step-by-step explanation:

So we are dealing with 11.50 - 11.50 + 1.15x = 12.65 - 11.50

our first step is Simplify both sides of the equation so:

11.5 + -11.50 + 1.15x = 12.65 + -11.50 turns into:

(1.15x) + (11.5+ -11.5)= (12.65 + -11.5)

**we know 11.5 + -11.5 will cancel each other since they are opposite**

so it will be 1.15x= 1.15

now the very last step is to divide 1.15x on both sides which gives us 1

The area of a square root is 2.25m2. what is the length of each side of the square?

Show work pls, thank you.

Answers

Answer:

1.5 m

Step-by-step explanation:

Area = length * width

or we can say

Area = side1*side2

since they are the same we can say

Area = side * side

which also means area = side^2

so we have the area and we want the side, we need the inverse operation for squaring something. the inverse of squaring something is square rooting

sqrt(Area) = side

side = sqrt(2.25)

= 1.5 m

I feel like i made a short story long but i hope it helped =)

A: 21
B: 22
C: 22.5

Answers

300-75= 225
225/10 =22.5

The answer is either c or b.if your teacher wants you to round down, then choose b because you can’t have half a dime

The answer is c because dimes are worth 10 so when you add it up including the 3 quarters you get 22.5 dimes

The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.

Answers

Step-by-step explanation:

Let the athletes be 3x and 2x.

Now, By the question we get,

(3x-12)/(2x+12) = 5/4

or, 12x-48= 10x+60

or, 2x = 108

so, x = 54

now

3x= 3×54= 162

2x = 2×54=108

The number of athletes were 162 in first team and 108 in second team originally.

x is the number of athletes on first team originally ( x > 12, x ∈ Nˣ )

y ----------------------------------------second------------------( y ∈ Nˣ )

The ratio of athletes in the two teams is 3:2

⇒ [tex]\frac{x}{y} =\frac{3}{2}[/tex] (1)

After 12 athletes move from first team to second, the ratio is 5:4

⇒ [tex]\frac{x-12}{y+12} =\frac{5}{4}[/tex] (2)

(1),(2) ⇒ [tex]\left \{ {{\frac{x}{y} =\frac{3}{2}} \atop {\frac{x-12}{y+12} =\frac{5}{4}} \right. <=>\left \{ {{x=162} \atop {y=108}} \right.[/tex]

So: The first team originally has 162 numbers and the second team originally has 108 numbers

ok done. Thank to me :>

The Ride of His Life When Jesse Senko was 12 years old, he had an experience that literally changed his life. Senko was snorkeling while on vacation in the Cayman Islands with his family when a large sea turtle swam near him. Senko naturally did what any 12-year-old boy would do and decided to grab the turtle and go for a ride. That turtle ride, in some ways, has never ended. People find their passions in many different ways. Senko found his passion while riding on the back of a turtle when he was just 12 years old. Today, Senko is a conservation scientist at Arizona State University. He focuses his research and lifes work on marine resource sustainability. Can you guess what that includes? If you guessed sea turtles, you would be correct. In college, Senko majored in fisheries and wildlife science, and he also received a Master of Science degree in wildlife ecology. Much of the focus of his work is on saving endangered sea turtles. Sea turtles help keep the ocean healthy, and thus their well-being affects the entire ecosystem. They provide a natural regulatory system for the environment. For example, sea turtles eat seagrass, which helps it grow properly, and their unhatched eggs provide nutrients for plant life to keep beaches healthy. Sea turtles also provide a home for small animals that attach to their shells. Sea turtles are endangered because fishermen inadvertently catch them in their nets, which can cause the turtles irreparable harm. Senko came up with the idea to create solar-powered fishing nets so fishermen can readily see when they accidentally catch a sea turtle. Because the lights are solar powered, the fishermen do not have to maintain the lights or change the batteries. This technology has resulted in a 65 percent reduction in sea turtle catches thus far. Senkos goal is a 100 percent reduction. Question 1 Part A What is a central idea of "The Ride of His Life"? Solar power is essential to saving sea turtles. Sea turtles are the most endangered animals in the ocean. Sea turtles are a critical part of the marine ecosystem.Modern technology such as solar nets will help save the environment.Part BWhich sentence from the text best shows the development of the central idea in Part A?"Today, Senko is a conservation scientist at Arizona State University. He focuses his research and lifes work on marine resource sustainability.""Sea turtles are endangered because fishermen inadvertently catch them in their nets, which can cause the turtles irreparable harm.""sea turtles eat seagrass, which helps it grow properly, and their unhatched eggs provide nutrients for plant life to keep beaches healthy.""This technology has resulted in a 65 percent reduction in sea turtle catches thus far."
