Answer:
Hi , the answer is 280-140/ 4-2 = 140/2
y = 2/140 x
b . 70 beats each minute
Step-by-step explanation:
we will take a 2 point from the graph
(280,4) , (y1,x1) and (140, 2) , (y2,x2) each point represent a (y,x) point
m = y1-y2 / x1-x2 = 280-140 / 4-2 = 140 /2
now , y/x = 140/2 ... by B. Multiplication we will get y = 2/140 x
b .
from the graph we see that every minute the curve increase 70 beats
Thanks
Answer:
6
Step-by-step explanation:
(10+2)/2
6
500ml ⇒ 80g
2500ml ⇒ x (g)
500x=80*2500 /500
x=80*5=400 (g)

Answer:
![{7a^{5}b^{5} c\\](https://tex.z-dn.net/?f=%7B7a%5E%7B5%7Db%5E%7B5%7D%20c%5C%5C)
Step-by-step explanation:
![\frac{28a^{8}b^{6} c^{3} }{4a^{3}bc^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B28a%5E%7B8%7Db%5E%7B6%7D%20c%5E%7B3%7D%20%20%7D%7B4a%5E%7B3%7Dbc%5E%7B2%7D%20%20%7D)
→ First look at the first term of each expression and see if they can be simplified, and they can
![\frac{7a^{8}b^{6} c^{3} }{a^{3}bc^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B7a%5E%7B8%7Db%5E%7B6%7D%20c%5E%7B3%7D%20%20%7D%7Ba%5E%7B3%7Dbc%5E%7B2%7D%20%20%7D)
→ Now look at the a terms, since a larger one is at the top, you subtract
![\frac{7a^{5}b^{6} c^{3} }{bc^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B7a%5E%7B5%7Db%5E%7B6%7D%20c%5E%7B3%7D%20%20%7D%7Bbc%5E%7B2%7D%20%20%7D)
→ Now simplify the b and c terms
![{7a^{5}b^{5} c](https://tex.z-dn.net/?f=%7B7a%5E%7B5%7Db%5E%7B5%7D%20c)
Answer:
600
Step-by-step explanation:
0+.80x=60+.70x
-.70x=60-.70x
.10x=60
÷.10=÷.10
C=600
0+.80(600)=480
60+.70(600)=480
