Answer:

C (30)

Step-by-step explanation:

They've already given us two sides of the triangle,

And since triangle AED has two sides that are equivalent in length, and side CD is 12, Side AC is also 12.

12+9+9= 30.

One and one over seventh times three fifths
andreyandreev [35.5K]

Answer:

24/35

Step-by-step explanation:

1) Convert your mixed number (1 and 1/7) to an improper fraction by multiplying your whole number (1) and your denominator (7) which gives you 7. Then add your numerator (1) to that which gets you 8. Then take the original denominator (7) and turn it into improper where your new numerator is 8 and your denominator stays 7. (If that doesn't make much sense then you can look up how to change mixed numbers into improper fractions.)

2) Multiply your numbers straight across.

8/7 * 3/5

8*3= 24

7*5= 35

24/35  you can't simplify this, so 24/35 is your answer

A parallel circuit consists of two capacitor c1=10mF and c2=15mF what is the total Capacitance
tensa zangetsu [6.8K]

Answer:

C = 25 mF

Step-by-step explanation:

Given that,

Two capacitors with capacitances 10mF and 15mF are connected in parallel.

We need to find the total capacitance of the capacitors.

For a parallel combination, the equivalent capacitance is given by :

C_P=C_1+C_2

Substituting the values,

C_P=10+15\\\\=25\ mF

So, the total capacitance of the combination of capacitors is 25 mF.

20 points!!!<br> volume of a cylinder problems please help
balandron [24]

Answer:

Step-by-step explanation:

Part A

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

1) radius = diameter/2 = 4/2 = 2 inches

Volume = 3.14 × 2² × 10 = 125.6 inches³

2) Volume = 3.14 × 20² × 50 = 62800 cm³

3) radius = 16/2 = 8 mm

Volume = 3.14 × 8² × 10 = 2009.6 mm³

4) Volume = 3.14 × 9² × 9 = 2289.06 ft³

Part B

The formula for determining the volume of a sphere is expressed as

Volume = 4/3πr³

Where

r represents the radius of the sphere.

5) Volume = 4/3 × 3.14 × 5³ = 523.3 cm³

6) radius = 24/2 = 12 inches

Volume = 4/3 × 3.14 × 12³ = 7234.56 inches³

7) Volume = 4/3 × 3.14 × 1³ = 4.2 ft³

8) radius = 42/2 = 21 mm

Volume = 4/3 × 3.14 × 21³ = 38772.72 mm³
