Please help this is algebra one

Step-by-step explanation:

5 inches on the map correspond to 210 miles (or even a bit more) in reality.

we do know, the real length of the state is 213 miles.

and 8 inches to 410 (or a bit more) miles.

but, in fact, in reality, Kansas is indeed 410 miles long.

so, let's see first about the consistency of the scale factors (our ratios) in every direction.

5 inches / 210 miles = 1/42

8 inches / 410 miles = 4/205 = 1/51.25

so, in order to be a true map, both directions must have the same scale factor.

to fit the whole map on one page we must go with the smaller scale ratio : 1/51.25

so,

A with the ratio 1/1 is wrong.

B wrong.

1 cm = 1/2.54 inches

1 km = 1/1.6 miles

so, the scale ratio here is

1 cm / 1km = 1/2.54 / 1/1.6 = 1.6 / 2.54

still far off of the 1/51.25 ratio.

C with the ratio 1/10 is wrong.

D wrong

1 ft = 12 inches

the ratio is therefore

12/100 = 3/25 = 1/8.3333

still far off of the 1/51.25 ratio.

E would fit

1 cm = 1/2.54 inches

1 km = 1/1.6 miles

200 km = 200/1.6

so, the scale ratio here is

1 cm / 200km = 1/2.54 / 200/1.6 = 1.6 / (2.54×200) =

= 1.6 / 508

still far off of the 1/51.25 ratio, but in the form of being much smaller. so it fits on the page.

F would fit.

the ratio is 1/100.

this is again far off of the 1/51.25 ratio, but also in the form of being much smaller, so it fits on the page.

G would fit.

1 cm = 1/2.54 inches

1 km = 1/1.6 miles

1000 km = 1000/1.6

so, the scale ratio here is

1 cm / 1000km = 1/2.54 / 1000/1.6 = 1.6 / (2.54×1000) =

= 1.6 / 2540

again far off of the 1/51.25 ratio, but also in the form of being much smaller. so it fits on the page.

Work Shown:

45.40 - 40 = 5.40

She made $5.40 in profit. Divide this over the original price to find the percentage profit

(5.40)/(40) = 0.135 = 13.5%

Answer:

20

Step-by-step explanation:

14/0.7

Answer:

Step-by-step explanation:

Your question: 70 percent of what number equals 14?

Step 1: Multiply both sides by 100 to get 7,000 and 1,400.

Step 2: Divide both sides by 70 to get 100 and 20.

Step 3: Put it into fraction form. [tex]\frac{20}{100}[/tex].

Step 4: Since in percentages, you typically only go up to 100, we can remove the 100 to leave us with just 20.

Step 5: We have our answer. 70% of 20 is 14.

Hope this helps! :D

Answer:

13

Step-by-step explanation:

Correct on edge

The function will be one-to-one only if c = 13.

A function is one-to-one if and only if each value in the range appears only once.

So, the given set will represent a one-to-one function if c takes a value that is not repeated in any of the other coordinate pairs.

We have:

(1, 2), (2, 3), (3, 5), (4, 7), (5, 11), (6, c)

For the given options, the only element that not already appears in one of the pairs is c = 13, so that is the correct option.

Answer:

-12

Step-by-step explanation:

Answer:

1: C) Yes, because the last digit is 6, which is divisible by 2

2: B) Yes, because the sum of 2+1+6=9, which is divisible by 3

3: C) Yes, because the last digit of the number is 0

Step-by-step explanation:

Let's start with the first one. Is 26 divisible by 2? Yes, it is, because the last digit is 6, which is divisible by 2. To check to make sure we are right, we simply divide 26 by 2. Can it be done? Yes, 26 divided by 2 is 13, so we are right.

What about number two? Is 216 divisible by 3? Well, the rules divisiblity rules change for 3. For three, the sum of the digits of the number must be divisible by three. Do 2, 1, and 6, when added together, equal a number that is divisible by 3? Well, 2+1+6 is 9, and 9 is divisible by three, so the answer is B.

For the last one we need to check the divisibility rule for ten. The rule is that if the number ends in 0, it is divisible by 10. Does 40,100 end in a zero? Yes, so the answer is C.

Answer:

Yes, it is linear

3x+y=15

Explanation:

Put the variables on opposite sides so that you have:

[tex]\frac{y}{3}[/tex]=5-x

Multiply by 3 on both sides

y=15-3x

Bring x back to y's side

3x+y=15

All done!

Answer:

subtract 20 from both sides

Step-by-step explanation:

1. To find the answer, let's actually try solving the equation first and find the 2nd step.

2. (Solving)

Step 1: Distribute 2 to each term.

Step 2: Subtract 20 from both sides.

3. Since we got that the second step was "subtract 20 from both sides," the answer is subtract 20 from both sides.

Answer:

p=-32

Step-by-step explanation:

Partial quotient is one of the ways of dividing expressions and numbers.

The quotient is given as:

[tex]\mathbf{352 \div 16}[/tex]

The first step is:

[tex]\mathbf{352 - (20 \times 16) = 32}[/tex]

The next step is:

[tex]\mathbf{32 - ([\ ] \times 16) = 0}[/tex]

Represent the blank with x

[tex]\mathbf{32 - (x \times 16) = 0}[/tex]

So, we have:

[tex]\mathbf{32 - 16x = 0}[/tex]

Collect like terms

[tex]\mathbf{16x = 32}[/tex]

Divide both sides by 2

[tex]\mathbf{x = 2}[/tex]

So, the value that goes into the box is 2.

The quotient is then calculated as:

[tex]\mathbf{Quotient = 20 + 2}[/tex]

[tex]\mathbf{Quotient = 22}[/tex]

Hence, the quotient is 22.
