Explain step by step =) Harry rides his bike 25 3/8 miles. Karen rides her bike 25 2/5 miles. Who rides farther?

Answers

Answer 1

To answer this question we need to use subtraction.
we need to make the denominators the same.
In order to make them the same we need to find the least common multiple, of 8 and 5.
The least common multiple(the smallest shared value of the two numbers) is 40.

Next we divide our old denominator 5 by 40, which gives us 8, we multiply 8 by the numerator 2, which gives us 16. So now we have 16/20. We have to do the same to the other side. 8÷40 = 5. 5 x 3 = 15. Now we have 15/20.

Now we have a brand new equation, 16/40 - 15/40. The answer is 1/40.
In a fraction the answer is 1/40, so Karen rides her bike further.

In decimal form the answer is 0.025.

I hope this helps!

Answer 2

We can see Karren rode farther

[tex]25[/tex] [tex]\frac{2}{5}[/tex] with a common denominator is:

[tex]5+3=8[/tex] [tex]2+3=5[/tex]

[tex]\frac{2}{5}+\frac{3}{3}=\frac{5}{8}[/tex]

so we know that Karren rode [tex]25\frac{5}{8}[/tex] miles which is more than Harrys [tex]25\frac{3}{8}[/tex]

Mary having her living room and bedroom painted. Interior Designs USA charges $60.00 to evaluate the space plus $35.00 per hour of labor. Splash of Color charges $55.00 per hour with no initial fee. Which of the following are true? Select all that apply.

Answers

The true statement are as follows:

If it takes more than 5 hours to paint the rooms, Splash of Color will be more cost effective.If it takes 3 hours to paint the rooms, both companies will charge the same amount.

Here's a breakdown of why each statement is true or false:

True:

If it takes more than 5 hours to paint the rooms, Splash of Color will be more cost effective. As the painting time increases, the hourly rate becomes a bigger factor, and Splash of Color's lower rate outweighs Interior Designs USA's initial fee advantage.

If it takes 3 hours to paint the rooms, both companies will charge the same amount. Both companies will charge 3 hours of labor at their respective rates: $35/hour * 3 = $105 for Interior Designs USA and $55/hour * 3 = $165 for Splash of Color.

False:

If it takes 7 hours to paint the two rooms, Interior Designs USA will charge the least. Interior Designs USA will cost $60 + $35/hour * 7 = $315, while Splash of Color will cost $55/hour * 7 = $385.

Splash of Color will always charge the least. This is not true because Interior Designs USA can be cheaper for smaller jobs due to their lack of an initial fee (e.g., 1 hour painting time).

If it takes 10 hours to paint the rooms, Splash of Color will charge $200 more than Interior Designs USA. Splash of Color will cost $55/hour * 10 = $550, while Interior Designs USA will cost $60 + $35/hour * 10 = $410. The difference is actually $140, not $200.

Complete question:

If it takes 7 hours to paint the two rooms, Interior Designs USA will charge the least.Splash of Color will always charge the least.If it takes more than 5 hours to paint the rooms, Splash of Color will be more cost effective.If it takes 10 hours to paint the rooms, Splash of Color will charge $200 more than Interior Designs USA.If it takes 3 hours to paint the rooms, both companies will charge the same amount.

Lee has a jar of 100 pennies. She adds groups of 10 pennies to the jar. She adds 5 groups. What numbers does she say?

Answers

100, 110, 120, 130, 140, 150. If counting by tens

If Lee starts with 100 pennies and adds groups of 10, the operation is addition. Since she does this 5 times, there is 5 different numbers Lee said.

100 + 10 = 110
110 + 10 = 120
120 + 10 = 130
130 + 10 = 140
140 + 10 = 150

Thus, all of the numbers she said were 110, 120, 130, 140, and 150.

Answers

So in 8^2 you're doing 8^2/1, which is the same thing, but in 8^-2, you're doing 1/8^2. This is 1/64, which is equivalent to 0.015625.

2n+5<13
minus 5 both sides
2n<8
divide by 2
n<4

Answer:

1. Using Backwards Method, we get,

We have the inequality 2n+5<13.

So, we subtract both the sides by 5,

i.e. 2n+5-5<13-5

i.e. 2n < 8

Now, divide both sides by 2, we get,

[tex]\frac{2n}{2} <\frac{8}{2}[/tex]

i.e. n < 4.

So, using the Backwards method, we get the solution is n<4.

2. Now, we use the Algebraic method,

We have, 2n+5<13

Take 5 to the right side of the inequality,

i.e. 2n<13-5

i.e. 2n < 8

Now, take the 2 on the right side of the inequality.

i.e. [tex]n<\frac{8}{2}[/tex]

i.e. n < 4.

So, again using the Algebraic Method, we get that the solution is n<4.

In the function y = 10.00x + 35, y represents the cost of cabin lodging per occupant and x represents the number of occupants. How much does the cost increase for every occupant?

Answers

y = 10x + 35

if y is cost per occupant and x is occupants, then we can read the equation as such:

Cost is equal to 10 times number of occupants plus a 35$ fee

10 times the number of occupants is the part we are worried about

The cost increases by 10$ for every occupant

Answer:

$10.

Step-by-step explanation:

We have been given a function [tex]y=10.00x+35[/tex], where y represents the cost of cabin lodging per occupant and x represents the number of occupants.

Since slope of a line is also known as unit rate, so the cost increase for every occupant will be equal to the slope of line.

We can see from our given expression that 10.00x represents the slope of line, so the cost increase for every occupant is $10.

Kelly Ann took 15 minutes to walk from her home to the library. Her average speed was 3 miles in 45 minutes. how far was it from Kelly Ann's house to the library? (PLEASE SHOW STEPS!!)

Answers

Ok; Since we know that in 45 min, she can walk 3 miles, we can divide it to see how many minutes it takes for her to walk 1 mile. 45 divided by 3 is 15. Which means it takes her 15 minutes to walk 1 mile. If we look back at the beginning, it says she takes 15 minutes. Now that we know that it takes her 15 minutes to walk 1 mile, the answer is that it takes her 1 mile to walk to the library.

Really simple.

You know that speed is v = d/t
so 3/45 = 1/15 or 1 mile per 15 mins

So since she took 15 mins i know the library is 1 mile

An alloy consists of nickel, zinc, and copper in the ratio 2:7:9. How much of each metal is needed to make 3.6 kg of this alloy?

Answers

Answer

Find out the how much of each metal is needed to make 3.6 kg of this alloy .

To proof

As given

An alloy consists of nickel, zinc, and copper in the ratio 2:7:9 .

This shows that an alloy contains 18 parts and assume one part of alloy be u .

Thus

An alloy consists of nickel = 2u

An alloy consists of zinc = 7u

An alloy consists of copper = 9u

As given

Total weight of alloy = 3.6 kg

Thus equation becomes

2u + 7u + 9u = 3.6

18u = 3.6

[tex]u = \frac{3.6}{18}[/tex]

u = 0.2 kg

An alloy consists of nickel = 2 × 0.2

= 0.4 kg

An alloy consists of zinc = 7 × 0.2

= 1.4 kg

An alloy consists of copper = 9 × 0.2

= 1.8 kg

Hence proved

Final answer:

To make 3.6 kg of alloy in the given ratio, 400 grams of nickel, 1400 grams of zinc and 1800 grams of copper are required.

Explanation:

The question is asking how much of each metal, namely nickel, zinc, and copper, is needed to make 3.6 kg of an alloy with a ratio 2:7:9. To solve this, first, we have to understand that the ratio represents relative amounts of each metal, not their exact weights. The entire alloy is made up of 2 parts nickel, 7 parts zinc, and 9 parts copper - a total of 18 parts. We can find the weight equivalent to one part by dividing the total weight of the alloy - 3.6 kg or 3600 grams - by 18. This gives us 200 grams as the weight of one part. To find the weight of each metal needed, we multiply the weight of one part by the number of parts in the ratio: nickel is 2 * 200 = 400 grams, zinc is 7 * 200 = 1400 grams, and copper is 9 * 200 = 1800 grams.
