Hey the answer should be (0,100). I checked on a graphing calculator so it should be correct. In the future, you should use Desmos graphing calculator. It’s free and it checks if where the two lines meet. :)

Using the scale given 1cm = 8km. Hatboro and Smithville are 24cm apart on the map. What is their actual distance (km) between the two cities?

Answers

Answer:

They are 192 km apart.

Step-by-step explanation:

? = unknown value

We can use the equation

? km = ?cm * 8

Or ratio

1/8 (What do you multiply 1 by to get to 8? 8. 1 is how many cm there are so if there are 24 cm then we multiply that by 8 as well.)

We have to multiply 24cm by 8 because of the ratio 1:8, 24 times 8 is 192.

The answer is 192km!

Given LMNP ∼ QRST, find RS.

Answers

Answer and Step-by-step explanation:

We know that shape LMNP is similar to shape QRST.

This means that the side LM is similar to side QR.

The shapes look dilated, so to find the scale factor, we would divide 45 by 27.

[tex]\frac{45}{27} = \frac{5}{3} , or 1.6^{-}[/tex] is the dilation factor.

So, to find x, we would divide 25 by [tex]\frac{5}{3}[/tex].

[tex]\frac{25}{\frac{5}{3} } = 25 * \frac{3}{5} = 15[/tex]

X is equal to 15.

17=11y+12x in slope intercept form please explain

Answers

Simplifying

17 = 11y + 12x

Reorder the terms:

17 = 12x + 11y

Solving

17 = 12x + 11y

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-12x' to each side of the equation.

17 + -12x = 12x + -12x + 11y

Combine like terms: 12x + -12x = 0

17 + -12x = 0 + 11y

17 + -12x = 11y

Add '-17' to each side of the equation.

17 + -17 + -12x = -17 + 11y

Combine like terms: 17 + -17 = 0

0 + -12x = -17 + 11y

-12x = -17 + 11y

Divide each side by '-12'.

x = 1.416666667 + -0.9166666667y

Simplifying

x = 1.416666667 + -0.9166666667y

If the area of the parallelogram is 15 cm 2, what is the area of the green triangle?



30 cm 2
15 cm 2
7.5 cm 2
8 cm 2

Answers

i think it would be 7.5!
the picture doesn't have a lot of info but to the looks of it the parallelogram is split into two equal triangles so if the parallelogram is 15 and you divide that by two since there are two triangles that look like the same it would be 7.5!
The triangle is half of the parallelogram, so that would be 7.5 cm 2

1 ton weighs 2,000 lbs. 1,800+180+18+1.8 is roughly the closest to a whole number that can be divided by 3 easily. 18 divided by 3 is 6, so next we’ll simply multiply 6. 600+60+6+.6=666.6 So now, we’ll round to the nearest 1’s place, being 667. Don’t forget to add unit of measurement, which is lbs to the end, making the answer 667 Lb’s

One foot equals 12 inches. Multiples of 12 include 12, 24, 36, and 48. 36 inches is the closest to 35 inches in that set of multiples. 36 inches equal 3 feet, so the answer is 3 ft.

Ratios can be used to convert units of measurement by simply multiplying the conversions of the desired unit to the amount you want converted.
