Answer:

The answer is <u>C : a cylinder with a base radius of 9 inches</u>

Step-by-step explanation:

The area is 270² inches,  and to find the area of a rectangle is width × length . So the equation would be 270 = W × L, which would convert to 270 = W × 15 and 15 times 18 equals 270. But that is not thew answer because you would need top find the radius of the cylinder which is half of the width of the rectangle which means the radius is 9. So the answer is a<u> cylinder with a base radius of 9 inches. </u>

What will be the annual salary for a mechanic who works 40 hours per week for 52 weeks a year and makes $25.21 per hour
dalvyx [7]
40 hours * 52 weeks = 2080 hours total worked that year. 

2080 hours * 25.21 paycheck = 52,436.80

In reality you would have to subtract out holidays, any vacation, any sick days and taxes. All of that information varies by location and company.

C and D are mutually exclusive events. Find P(C or D).<br> P(C)= 3/7= P(D)= 4/7<br> P(C or D)
IgorLugansk [536]

Answer:

P(C\ or\ D) = 1

Step-by-step explanation:

Given

P(C) = \frac{3}{7}

P(D) = \frac{4}{7}

Required

P(C\ or\ D)

Since the events are mutually exclusive, then:

P(C\ or\ D) = P(C) + P(D)

So, we have:

P(C\ or\ D) = \frac{3}{7} + \frac{4}{7}

Take LCM

P(C\ or\ D) = \frac{3+4}{7}

P(C\ or\ D) = \frac{7}{7}

P(C\ or\ D) = 1

Given: <br> ΔABC, m∠C = 90º, m∠B = 30º<br> CM - angle bisector<br><br> Find: m∠AMC
SashulF [63]

Answer:

75°

Step-by-step explanation:

1. Consider right triangle ABC. In this triangle

m∠C = 90º and CM - angle bisector.

If CM is angle C bisector, then

m∠ACM = m∠MCB = 45º

2. Consider triangle CMB. The sum of the measures of all interior angles of the triangle is always 180°, then

m∠MCB + m∠CBM + m∠BMC = 180°,

m∠BMC = 180° - 45° - 30°

m∠BMC = 105°

3. Angles AMC and BMC are supplementary angles, so

m∠AMC + m∠BMC = 180°

m∠AMC = 180° - 105°

m∠AMC = 75°
