Last question! Any explanation is appreciated, sorry for bad quality

Lesechka [4]

Answer:

1/2

Step-by-step explanation:

When you have two points you need to use the slope formula:

$m=\frac{y_{2}-y_{1} }{x_{2}-x_1}$

x1 and y1 is the first point and x2 and y2 is the second point, remember that the first number is X and the other is Y so...

$m=\frac{5-4}{3-1} \\m=\frac{1}{2}$

1/2 is the slope of the points

3/4 divided by 2/3 using fractions

mr_godi [17]

To solve this divition we can write it like:

$\frac{\frac{3}{4}}{\frac{2}{3}}$

So now we can multiplicate the numerator of the first fraction with the denominatior of the second fraction, and put the resould in the numerator of the quationt, ans the same operation for the numeratior with the numerator of the secon fraction and the denominator of the first fraction so:

$\frac{3\cdot3}{4\cdot2}=\frac{9}{8}$

Sprinters who run 100 yards now often run 100 meters.

Marina CMI [18]

Answer:

100 meters is 8.6 meters longer than 100 yards.

Step-by-step explanation:

Conversion of yards to meters.

Each yard has 0.914 meters.

So 100 yards is 100*0.9144 = 91.4 meters.

How many meters longer to the nearest tenth is 100 meters than 100 yards?

100 yards = 91.4 meters

100 - 91.4 = 8.6

So 100 meters is 8.6 meters longer than 100 yards.

A cistern is leaking 0.25 liters of water per minute. Approximately how many gallons of water is the cistern losing per hour?

algol [13]

Hello,

$0.25 \dfrac{l}{min} = \dfrac{0.25\ l}{ \dfrac{1\ min}{60}} =15\ \dfrac{l}{h} \\

= \dfrac{15\ \dfrac{l}{h} }{3.78541\ \frac{l} {US\ gallon} })\\

= 3,96258265... \dfrac{US\ gallon}{h}$
