Answer: 21
Step-by-step explanation: We can rewrite this problem as:
What is 60% of 35?
"Percent" or "%" means "out of 100" or "per 100", Therefore 60% can be written as 60/100
When dealing with percent's the word "of" means "times" or "to multiply".
Finally, lets call the number of members we are looking for "m".
Putting this altogether we can write this equation and solve for
m
while keeping the equation balanced: m=60/100*35
m=2100/100
m=21
Answer:
15
Step-by-step explanation:
Substitute the values of the lengths and base in the formula for the perimeter
Perimeter = 2 (L) + b
121 = 2 (4x - 7) + x
121 = 8x - 14 + x
121 = 9x -14
121 + 14 = 9x
135 = 9x
x = 15
Answer:
Rate = 108 km/hr
Distance travelled in 2 hours = 216 km
Step-by-step explanation:
A car is travelling at a rate of 30 meters per second
1 km = 1000 meters
? km = 30 meters
Cross multiplying gives; km
1 hr = 3600 seconds
? hrs = 1 second
Cross multiplying gives; hrs
Speed = Distance ÷ Time
Speed in km/hr = km ÷ hrs = km × = 108 km/hr
Distance travelled in 2 hours = 2 × 108 km = 216 km
slope = 3
y-intercept = 1
explanation
slope, m = (y2-y1)/(x2-x1)
= (19-10)/(6-3)
= 9/3
= 3
equation of a line is y = mx + c
at point (3,10)
=> 10 = 3*3 + c
=> c = 10-9
=> c = 1
finding y-intercept when x = 0
y = mx + c
by putting the values we have
y = 3*0 + 1
y = 1
