7.85 is the approximate answer. (If pi is 3.14)
Steps are on paper.
Answer:
B, H
Step-by-step explanation:
The electrician charges 45 dollars per hour and 30 at the beginning. We are multiplying the hours, h, by 45 to get 45h. We add 30 to get C=45h+30
Jerome will always earn 75 dollars, but he also gets 10 percent commission, which is 0.10.
You need 864.52 sq. in. of blue tile.
We need to find the area of the large circle (including blue and yellow) and the area of the yellow circle.
We have the circumference of the blue circle, 113.097.
C = πd
113.097 = 3.14d
Divide both sides by 3.14:
113.097/3.14 = 3.14d/3.14
36.018 = d
The diameter is twice as much as the radius, so r = 36.018/2 = 18.009.
The area of a circle is given by the formula
A = πr²
A = 3.14(18.009)² = 1018.38 sq. in.
The area of the small yellow circle is given by
A = 3.14(7²) = 3.14(49) = 153.86
Subtracting these two, we have
1018.38 - 153.86 = 864.52 sq. in.
Answer:I can do it
Step-by-step explanation:
Answer:
y = 2x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, thus
y = 2x + c ← is the partial equation
To find c substitute (5, 6) into the partial equation
6 = 10 + c ⇒ c = 6 - 10 = - 4
y = 2x - 4 ← equation of line
