The radius of a circle is just half the diameter. So to find the radius from the diameter, just divide the diameter by 2:

$radius=\frac{diameter}{2} = \frac{5 \text{ mm}}{2} =2.5 \text{ mm}$

That's the radius.

Pick Two Points on the Line. Use "Rise over Run" to Find the Slope.<br> T<br> ✓

inn [45]

Answer:

Easiest to pick (0, 0) and (1, 1) probably, then slope is 1.

Step-by-step explanation:

Rise over run for (0, 0) and (1, 1) is rise up 1 and run over 1, so 1/1.

This means slope is 1

Solve for x. 5 x − 19 ≤ 1 OR − 4 x + 3 < − 6

k0ka [10]

$5x - 19 \leqslant 1$

change

$\leqslant \: to \: =$

given you

$5x - 19 = 1$

making x the subject by transferring the -19 to the right hand side of the equation

$5x = 19 + 1$

$5x = 20$

dividing through by 5

$\frac{5x}{5} = \frac{20}{5}$

$x = 4$

{ ${x:x \leqslant 4}$ }

also given

$- 4x + 3 < - 6$

change the operation sign to =

$- 4x + 3 = - 6$

$- 4x = - 6 - 3$

$- 4x = - 9$

dividing through by -4

$\frac{ - 4x}{ - 4} = \frac{ - 9}{ - 4}$

$x = \frac{9}{4}$

so the truth set is

{x:x>9/4}.

The < sign changes to > because we divided by a negative number when solving for x

In the garden, the ratio of roses to daisies is 1:3. There are 8 roses. How many daisies are there.

ivann1987 [24]

24 daises is the answer because if there is 8 roses and the ratio is 1:3 then you would multiply 8 by 3 to solve.

Olegator [25]

Answer:

1/1 or 1

Step-by-step explanation:

1. Find two points from the graph

2. Set them in the slope formula ( $\frac{y^2- y^1}{x^2 - x^1}$ )

3. Insert the coordinates into this formula

Points: (0,1) and (1, 2)

2 -1 = 1

1 - 0 = 1

1/1 = 1
