What is the slope of the line passing through the two points (-5,0) and (0,19)

lara31 [8.8K]

Slope m=(y2-y1)/(x2-x1)
(x1,y1)=(-5,0)
(x2,y2)=(0,19)
m=19-0/0-(-5)
m=19/5=3.8
Slope is 3.8
Good luck.

Ming drew the model to represent the equation 24+12=_x(8+4). What is the missing value in Ming's equation 3 4 12 24

Anika [276]

Answer:

3 is the missing value

Step-by-step explanation:

Given

$24 + 12 = \_ * (8 + 4)$

Required

Complete the blank

The model is not given; but the question can still be solved.

We have:

$24 + 12 = \_ * (8 + 4)$

Add 8 to 4

$24 + 12 = \_ * 12$

Add 24 to 12

$36= \_ * 12$

Divide both sides by 12

$3= \_$

Rewrite as:

$\_ = 3$

Hence, the blank will be completed with 3

aev [14]

Answer:

52.4 cm

Step-by-step explanation:

Circumference of a circle = 2πr

Radius, r = diameter / 2

= 17 cm / 2

= 8.5 cm

π = 3.14

Circumference of a circle = 2πr

= 2 × 3.14 × 8.5

= 53.38 cm

Approximately 52.4 cm
