Q 4
we know that a pie chart is a circle
we know that a circle is 360 degrees
so we multiply 7/10 with 360 and get the degrees
252 degrees
off topic, question 3 is wrong because if you want to round to 1 sig fig, you would look at the 100ths place to round to the 10th's place so 0.000 (disregard the 9 because it's too far away) rounded up =0
Step-by-step explanation:
Question 8)
2,8,14
d=a2-a1
d=8-2=6
a77= 2+ (76)*6
a77= 2+456=458
a77= 458
Question 9)
-12,-17,-22
d= -17+12= -5
a82= -12+ (81)*(-5)= -12-405= 417
a82= 417
Question 10)
9,13,17
d= 13-9= 4
a49= 9+ (48)*4= 201
a49= 201
Answer:
11y is the exact value.
Step-by-step explanation:
Area=hxw
h=a/w
h=120/10
12=120/10
h=12
Answer:
y = 5x-7
Step-by-step explanation:
y-y/x-x = slope
-12-3/-1-2 = -15/-3 = 5
next plug in slope and coordinates
y=mx+b
3=5(2)+b
solve for b
3=10+b
-7=b
