Hey! Can someone help with this problem? 30 POINTS and 5 stars if you help with all
Nezavi [6.7K]

Answer:

A: (-1,0)

B: (1,1)

C: (5,3)

(0,½)

(7,5) doesn't lie on the line

Step-by-step explanation:

Slope: (3-1)/(5-1) = ½

y = ½x + c

0 = ½(-1) + c

c = ½

y = ½x + ½

(0,½) is on the line

y = ½x + ½

Check for (7,5)

5 = 7/2 + 1/2

5 = 4 is a false statement

A lion’s heart beats 12 times in 16 seconds.how many heartbeats will it have in 60 seconds?
Sergio [31]
Hey there!

Here is your answer:

<u><em>The proper answer to this question is "44 times".</em></u>

Reason:

You have to solve it this way:

<u><em>12 heartbeats=16 seconds</em></u>

<u><em>16+16=32</em></u>
<u><em>36+16=48</em></u>
<u><em>48+16=64</em></u>
<u><em>16-12=4</em></u>
<u><em>12+12=36+8=44</em></u>

<em>Therefore lions heart beats 44 times every 60 seconds.</em>

If you need anymore help feel free to ask me!

Hope this helps!

ae=160
Bottom face:
A2(a+2d)×e=(20+2×5)×8=(20+10)×8=30×8
(a+2d)e=240

Total surface area
A=A1+A2+2(A3+A4)
A1=160
A2=240
A3=300
A4=104
Thus,
A=160+240+2(300+104)
A=400+2(404)
A=400+808=1208
