Please help im just a middle schoolor!!!!! The distance between City A and City B is 250 miles. A length of 1.7 feet represents this distance on a certain wall map. City C and City D are 3.74 feet apart on this map. What is the actual distance between City C and City​ D?

Answer:

Distance between City C and City D is 550 miles

Step-by-step explanation:

Given that:

City A and City B are 250 miles apart with a length of 1.7 feet;  &

City C and City D are x miles apart with a length of 3.74 feet.

To find the distance ( in x miles) between City C and City D, we use the ratio or proportionality concept.

i.e

250 miles = 1.70 ft

x miles =  3.74 ft

By cross multiplying, we get:

(250 * 3.74) = ( x * 1.70)

x = (250 * 3.74)/ 1.70

x = 550 miles.

Thus, the distance between City C and City D is 550 miles

Answer:

The slope of the graph is 3/4

Step-by-step explanation:

Answer:

If the line goes through 20,10, and 60, 40, then the slope is 3/4.

Answer:

A

Step-by-step explanation:

I would go with A. If this is wrong I'm so so so sorry, Although this is still what I think is correct.

Answer:

To determine the y-intercept, convert the equation into slope-intercept form.

x + 2y = -4

Subtract x from both sides

2y = -x-4

divide by 2 on both sides

y = -1/2(x) - 2 (this is the formula, with a slope of -1/2 and y-intercept of -2

This gives you a y-intercept of -2, which can be plotted at (0, -2)

For the x-intercept, plug in 0 for y into the formula.

x + 2y = -4

x + 2(0) = -4

x + 0 = -4

x=-4

This gives you an x-intercept of -4, which can be plotted at (-4, 0). Put those two numbers on the line and graph it, remembering that your slope is -1/2

Hope this helps!

Answer:

Step-by-step explanation:

To find the first table y = 4x + 2, to find each y value we have to substitute each x value into the equation.

4(-2) + 2 = -6 so -2 is going to have the y as -6

4(-1) + 2 = -2 so -1 is going to have the y as -2

4(0) + 2 = 2 so 0 is going to have the y as 2

4(1) + 2 = 6 so 1 is going to have the y as 6

4(2) + 2 = 10 so 2 is going to have the y as 10

So these are the points you would graph (-2, -6), (-1, -2), (0, 2), (1,6), and (2, 10)

For the next talbe y = 3x + 1 we do the same thing

3(-2) + 1 = -5 so -2 is going to have the y as -5

3(-1) + 1 = -2 so -1 is going to have the y as -2

3(0) + 1 = 1 so 0 is going to have the y as 1

3(1) + 1 = 4 so 1 is going to have the y as 4

3(2) + 1 = 7 so 2 is going to have the y as 7

The ooints to graph are (-2, -5), (-1, -2),(0,1), (1, 4) and (2,7)

For the next table y = 6x - 5

6(-2) - 5 = -17 so -2 is going to have the y as -17

6(-1) - 5 = -11 so -1 is going to have the y as -11

6(0) - 5 = -5 so 0 is going to have the y as -5

6(1) - 5 = 1 so 1 is going to have the y as 1

6(2) - 5 = 7 so 2 is going to have the y as 7

The points to graph (-2, -17), (-1, -11), (0, -5), (1, 1) and (2, 7)

For the next table y = 5 + 2x

5 + 2(-4) = -3 so -4 is going to have the y as -3

5 + 2(-2) = 1 so -2 is going to have the y as 1

5 + 2(0) = 5 so 0 is going to have the y as 5

5 + 2(3) = 11 so 3 is going to have the y as 11

5 + 2(5) = 15 so 5 is going to have the y as 15

(-4, -3), (-2, 1), (0, 5), (3, 11) and (5, 15)

For the next table y = 8x - 10

8(-4) - 10 = -42 so -4 is going to have the y as -42

8(-2) - 10 = -26 so -2 is going to have the y as -26

8(0) - 10 = -10 so 0 is going to have the y as -10

8(2) - 10 = 6 so 2 is going to have the y as 6

8(4) - 10 = 22 so 4 is going to have the y as 22

(-4, -42), (-2, -26), (0, -10), (2, 6) and (4, 22)

For the last table

2(-2) = -4 so -2 is going to have the y as -4

2(-1) = -2 so -1 is going to have the y as -2

2(0) = 0 so 0 is going to have the y as 0

2(-1) = -2 so -1 is going to have the y as -2

2(-2) = -4 so -2 is going to have the y as -4

(-2, -4), (-1, -2), (0, 0), (-1, -2) and (-2, -4)

Answer:

[tex]y=-\frac{2}{5} x+3[/tex]

Step-by-step explanation:

Slope, line, form.

y=mx+b

Points: 0,3 and -5,5

Find slope: 5-3/-5-0 or -2/5

y=-2/5x+b

5=-2/5(-5)+b

5=2+b

b=3

y=-2/5x+3

Answer:

Step-by-step explanation:

Step one:

given data

principal p= $2000

Rate r= 1.75% = 0.0175

time t= 18-16= 2years

Required

The final amount of the compounded principal

The compound interest formula is

A=P(1+r)^t

A=2000(1+0.0175)^2

A=2000(1.0175)^2

A=2000*1.0353

A=2070.6

All Angles Added: 180

Measures of Idiviudual Angles

A=70   C=70  B=40

-------------------------------------------------------------------------------

Step-by-step explanation:

All angles of a triangle when combined must equal 180 degrees.

Since the triangle is an isosceles triangle, at least 2 sides must be congruent meaning that A=C since the triangle is not equilateral.

Answer:

[tex]\frac{5}{4}[/tex]

Step-by-step explanation:

Given expression:

           [tex]\frac{3}{5}[/tex](y - 5)   =  - (y + 3) + 2

    To solve this problem, multiply both sides by 5;

  5 x   [tex]\frac{3}{5}[/tex](y - 5)   = 5[-(y + 3) + 2}

         3(y - 5) = 5(-y - 3 + 2)

         expand,

          3y - 15  = 5(-y -1)

          3y -15  = -5y - 5

    Collect like terms;

          3y + 5y  = -5 + 15

             8y  = 10

               y  = [tex]\frac{10}{8}[/tex]  = [tex]\frac{5}{4}[/tex]

Answer:

The watermelon candies taste $0.13 more.

Step-by-step explanation:

First, in order to find out how much each candy costs per ounce, you have to take the cost and divide it by the number of ounces. 3.48 divided by 12 is 0.29, so the watermelon candies cost $0.29 per ounce. 1.38 divided by 8 is 0.16, so the chewy chocolates cost $0.16 per ounce. In order to find how much more the watermelon candies cost, we have to subtract the cost of the watermelon candies by the cost of the chocolate candies. 0.29-0.16=0.13, so the watermelon candies cost $0.13 more than the chocolate candies.

Given:

Jason buys three shirts with a listed price of $20 each.

He uses a coupon that provides "Buy Two, Get One Free".

To find:

The total final price Jason pays.

Solution:

Total number of shirts he buys = 3

Since he uses a coupon that provides "Buy Two, Get One Free", therefore he need to pay for 2 shirts and 1 he will get free.

Cost of 1 shirt = $20

Cost of 2 shirts = 2 × $20

                        = $40

Therefore, total final price Jason pays is $40.

Given :

Heidi uses 5 grams of tea leaves to make 25 fluid ounces of tea.

Last week she made 75 fluid ounces of tea.

To Find :

How many grams of tea leaves did Heidi use to make tea last week.

Solution :

Let, x gram of leaves are required last week.

So,

[tex]\dfrac{x}{5}=\dfrac{75}{25}\\\\x = 5\times\dfrac{75}{25}\\\\x = 5\times 3\\\\x = 15 \ grams[/tex]

Therefore, 15 grams of tea leaves is used last week.

Hence, this is the required solution.

Answer:

The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept.
