What is the position of F on the number line below? write your answer as a fraction or mixed number

nadya68 [22]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

There are 4 steps to complete to go from 0 to 1. Hence each step is:

1 out of 4, or simply $\frac{1}{4}$

F is located at the 3rd mark, which will be $\frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{3}{4}$

Hence, F is located at $\frac{3}{4}$

Answer:

11: Diameter

13: 10 cm

Step-by-step explanation:

Diameter is a straight line across a circle.

It would be 10 because if you cut 20 in half, which is the whole distance of the line, you would get 10.

Write an equation of the line that passes through (-4,-1) and is perpendicular to the line y=4/3x+6

Sonja [21]

Answer:

$y=-\dfrac{3}{4}x-4.$

Step-by-step explanation:

If needed line is perpendicular to the line $y=\dfrac{4}{3}x+6,$ then its slope satisfies condition

$m\cdot \dfrac{4}{3}=-1\Rightarrow m=-\dfrac{3}{4}.$

Then the equation of needed line will have look

$y=-\dfrac{3}{4}x+b.$

Since this line passes through the point (-4,-1), then

$-1=-\dfrac{3}{4}\cdot (-4)+b,\\ \\-1=3+b,\\ \\b=-1-3=-4.$

Hence, the equation is

$y=-\dfrac{3}{4}x-4.$
