Answer:
x= 7
Step-by-step explanation:
add (12x+1) and (5x-3) which becomes 17x-2 and then set that equal to 117 and solve. move the 2 to the right side of the equation which becomes 17x=119 and then divide 119 by 17 which x equals 7.
plug in 7 for x to make sure you get 117
Answer:
39.6 cm
Step-by-step explanation:
Applying
s = 2πrθ/360................ Equation 1
Where s = length of an arc or distance traveled by the minutes hand of the clock during the 42 munites, r = length of the minutes hand of the clock, θ = Angle traveled by the minute hand of the clock for every 42 minutes
From the question,
Given: r = 9 cm, θ = 252°
Constant: π = 22/7 = 3.14
Substitute these values into equation 1
s = (2×3.14×9×252)/360
s = 39.564
s = 39.6 cm
Answer:
m = 20
Step-by-step explanation:
We have two fractions and are asked to find m.
When we have a question like this, cross multiplying is our key, to find m, we need to first find the value of the denominator of the other fraction and the numerator of the same fraction m is in.
Therefore :
What is 8 * 15?
120.
Now we need to find what times 6 equals 120 to get m.
Divide 120 by 6
20
Therefore, m is equal to 20
The volume of a sphere is 4/3 pi, times its radius cubed.
To cube the radius you multiply the radius times itself 3 times.
3 x 3 x 3 =27
4/3 pi x 27 = 113.1.
113.1 rounded to the nearest tenth is the same.
