Dudley is biking. He wants to cover 40 miles. If he travels 30 miles every 2 hours, what is the equation of a line that models y, the number of miles he has left to travel, after biking x hours?

Answers

Answer 1

Answer:

Equation of a line that models y is:

y=40-15x

Step-by-step explanation:

Dudley wants to cover 40 miles.

If he travels 30 miles every 2 hours

in 2 hours he covers 30 miles

i.e. 1 hour he covers 15 miles

Miles he is left with after 1 hour=40-15

Miles he is left with after 2 hours=40-15-15=40-15×2

Miles he is left with after x hours of biking=40-15x

If y represents the number of miles he has left to travel, after biking x hours

then, y=40-15x

Hence,  equation of a line that models y is:

y=40-15x

Answer 2

Answer:

It is y = -15x + 40

the function f(h)=2d+4.3 relates the h height of the water in a function on a calculator and use the graph to find the height of the water when the pipe has a diameter of 1.5 inches.

Answers

So, if "d" equals the diameter, we need to plug in 1.5 for "d". The equation now looks like: f(h) = 2(1.5) +4.3. Now if you multiply, it's: f(h) = 3 + 4.3, which then is: f(h) = 7.3. The height would be 7.3 in, when the diameter is 1.5 in. Hope this helps =). Have a great day! 

Answer:

The height of water is 7.3 inches, when diameter of pipe is 1.5 inches.  

Step-by-step explanation:

We are given the following information in the question:

[tex]f(h) = 2d + 4.3[/tex]

where f(h) is a function for height of water and d is the diameter of pipe in inches.

We have to calculate height of water when d = 1.5 inches.

Putting d = 1.5 in the above equation, we get:

[tex]f(h) = (2\times 1.50)+ 4.3 = 7.3[/tex]

Hence, the height of water is 7.3 inches, when diameter of pipe is 1.5 inches.

Given ABCDEF ≅ GHIJKL . What is the measure of ∠K ? Enter your answer in the box. ​ m∠K ​ = blank °

Answers

≅ means that both have the same values, therefore, m<K=114°

Hello!  Let me help!

Answer: 114

Step-by-step explanation: So, I gave you an answer, but how is it right?  If you see between ABCDEF and GHIJKL there is ≅.  That means congruent, and or equal (identical.)  

So, looking at ABCDEF, the fifth letter is E.  Then look at the other one, the fifth one is K. Which, K is what we're trying to figure out. Well, if the angles are congruent all letters are equal to the other letters.  So, Look for E on the left-hand shape.  WOAH! What does it show over top of the letter?! Oh! It's 114.  Which means.

The answer means E ≅ K. Which also means.  E ≅ 114. and!  114≅K.

write a sequence that has three arithmetic means between 35 and 45

Answers

45 - 35  = 10 
so we divide by 4  10/4 = 2.5 
The sequence is  35, 37.5, 40, 42.5, 45

The required sequence is 35, 37.5, 40, 42.5, 45

Given that,
To determine a sequence that has three arithmetic means between 35 and 45.

What is arithmetic progression?

Arithmetic progression is the series of numbers that have common differences between adjacent values

Here,
The difference in the number 45 and 35,
= 45 - 35
= 10
We have to add 3 numbers between 35 to 45
The total number of difference become 4 between the 5 numbers
mean of difference = 10 / 4
                                = 2.5
Now the sequence is given as,
35, 35+2.5, 35+ 2 * 2.5 + 35  + 3 * 2.5 + 45
35, 37.5, 40, 42.5, 45

Thus, the required sequence is 35, 37.5, 40, 42.5, 45

Your best bet may be to modify (convert) each number so that the denominator is the same (find the LCD and use it).

Generally, it's easier to convert a proper fraction to a decimal fraction than to do the opposite.  Thus, convert 1/3 to a decimal fraction by division (use your calculator if need be):  1/3 = 0.33333 (repeating decimal).  Convert 1 1/4 to 1.25.

Now you have four numbers that are all in decimal fraction form:  0.33333, 1.25, 0.27, 1.35.  Which of these four is the smallest?  Right:  0.27.  Next?  0.33333.  Next? 1.25.  Last?  1.35.

the 7 in the thousands place is 10 times greater than the 7 in the hundreds place?

the 7 in the thousands place is 100 times greater than the 7 in the hundreds place?

the 7 in the thousands place is 7 times greater than the 7 in the hundreds place?

Answers

The first one is correct. The 7 in the thousands place is 10 times greater than the 7 in the hundreds place.
Final answer:

The 7 in the thousands place is ten times greater than the 7 in the hundreds place, adhering to the base-10 structure of our numbering system; other proposed multipliers are incorrect.

Explanation:

The question explores the concept of place value in our decimal numbering system, which is based on powers of ten. Specifically, it examines the comparative value of digits in the thousands and hundreds places. Using the decimal system, each place value to the left is ten times greater than the one immediately to its right.

The second statement suggesting that the 7 in the thousands place is 100 times greater is incorrect; it overlooks the base-10 structure of our numbering system. Finally, the suggestion that the 7 in the thousands place is 7 times greater is also incorrect, as it misinterprets the multiplicative property of the decimal system. Therefore, the 7 in the thousands place being 10 times, 100 times, or 7 times greater than the 7 in the hundreds place aligns with the concept of powers of 10.

bob switches cell phone plans from Verizon to Tmobile. the monthly cost of his new plan is half the cost of his old plan, plus he added the iPhone 6s to his new plan which costs an additional $27.50 per month. If Bob's new monthly bill with Tmobile is $70 total(plan and phone), then how much is he saving per month by switching from Verizon to Tmobile? (analyze, equation, solve, check and interpret, conclusion)

Answers

First you need to divide 70 by 2 in order to cut it in half which would give you 35. Then add 27.50 and you get 62.5. Subtract that from 70 and you get 7.50 so he saved $7.50 each month 
Final answer:

Bob is saving $15 every month by switching his mobile phone plan from Verizon to Tmobile.

Explanation:

This question involves understanding and solving a mathematical equation associated to a real-life context, which in this case refers to mobile phone plans and their costs. Using the provided information, we first establish that Bob's plan with Tmobile costs $70 per month, and this includes the cost of his new iPhone 6s which adds an additional $27.50 to his monthly plan.

Based on these numbers, we can uncover the cost of the plan itself (excluding the phone) by subtracting $27.50 from $70, giving us $42.50. This, according to the question, is half the cost of Bob's old Verizon plan. Therefore, to find the total cost of the Verizon plan, we double the cost of the Tmobile plan, resulting in $85 per month.

So, the monthly savings Bob makes by switching from Verizon to Tmobile is the difference between the old Verizon cost ($85) and the new T-mobile cost ($70), which amounts to $15.

What's method 2 and what is the unit rate per guest?

Answers

Seeing your method 1 answer, it seems like you forgot that 42 dollars is for 6 guests, not just 1. The unit rate is the rate per guest, and if we divide 42 by 6, we get 7dollars/1person as our unit rate. Since 7 dollars is our unit rate, we can multiply that by 72 to get 504 dollars, therefore making 500$ per night more cost effective.

Another way to do this is to do 42*72, as you did, but then dividing the final product by 6 due to that 42*72 is for 72*6=432 guests (we get the 6 since the unit rate is 7$ per person and 42/7=6). Doing that, we get 3024/6=504, which is still greater than 500

Note the following:
1. A substance solidifies (becomes solid) when its temperature falls below the melting point.
2. A substance becomes liquid when its temperature is higher than the melting point but is lower than the boiling point.
3. A substance becomes gas when its temperature is higher than the boiling point.

Given:
The room temperature is 20°C. This is the temperature of the substance.

Let us identify substances A, B, and C.

Substance A is a solid.
For iodine, 20°C < 110°C (its melting point), iodine is substance A.
Therefore iodine is a solid.

Substance B is a liquid.
For bromine, 20°C > -7.2°C (its melting point), and also 20°C < 59°C (its boiling point).
Therefore bromine is a liquid.

Substance C is a gas.
For chlorine, 20°C > -35°C (its boiling point), therefore chlorine is a gas.

Answer:
Substance A is iodine.
Substance B is bromine.
Substance C is chlorine.

multiply using partial products . Record the products 56x 32

Answers

Final answer:

To multiply 56 by 32 using partial products, break down the numbers into their place values, multiply each component, and add the partial products to get the final product, which is 1792.

Explanation:

To multiply 56 by 32 using the method of partial products, you break down each number into its place value components and then multiply each component of the first number by each component of the second number before adding all the products together.

First, break down 56 into 50 and 6.

Second, break down 32 into 30 and 2.

Multiply each part of 56 (50 and 6) by each part of 32 (30 and 2) separately:

50 x 30 = 1500

50 x 2 = 100

6 x 30 = 180

6 x 2 = 12

Finally, add all these partial products together:

1500 + 100 + 180 + 12 = 1792

The product of 56 and 32 using partial products is 1792.
