Answer: The greatest common factor of 39,42, and 33 is 3

Step-by-step explanation:

We first find the factors of the numbers

39=1x39, 3x13     (1,3,13,39)

42=1x42, 2x21, 3x14, 6x7(1,2,3,6,7, 42)

33=1x33, 3x11(1,3,11.33)

The common factors are the factors that appear in the three numbers which are 1 and 3

The greatest common factor therefore is 3

Sam runs for 10 minutes The graph shows his puse, in beats per minute. 100- (beats per min) 80- 1 2 3 5 6 7 8 9 10 Time (min) By
Inessa05 [86]

The rate at which his pulse is increasing after 3 minutes is 9.5 beats per minute

<h3>How to determine the beat rate after 3 minutes?</h3>

The given graph shows the curve and the tangent.

From tangent line, we have the following points:

(x,y) = (3,119) and (1,100)

The beat rate (m) at this point is:

m = \frac{y_2 -y_1}{x_2 -x_1}

So, we have:

m = \frac{100 - 119}{1 - 3}

Evaluate the differences

m = \frac{-19}{-2}

Evaluate the quotient

m = 9.5

Hence, the rate at which Sam's pulse is increasing after 3 minutes is 9.5 beats per minute

Can someone help me out?
Anarel [89]

Answer:

So the value of s  = 7 cm

Step-by-step explanation:

We know that, Area of a triangle = 1/2 * b * h

So, base = 24 cm

height = s

Area = 1/2 * b * h

=>84 = 1/2 * 24 * h

=>84 = 12 * h

=>84 / 12 = h

=> 7 = h (in cm)

Hope this helps, please mark me as brainliest!! Thank you!

There was a layer of snow on joes driveway when it began to snow again. As the snow fell, joe measure the depth, in centimeters
OLga [1]
The minutes will be ur x axis and the cm of snow will be ur y axis

(10,2),(30,3.6).....using 2 points and the slope formula : (y2 - y1) / (x2 - x1)

slope = (3.6 - 2) / (30 - 10) = 1.6 / 20 = 0.08 cm per minute <===
