What is the answer of 7/4÷3/5​

Mathematics
1 answer:
Mandarinka [93]3 years ago
7 0

Answer:

2\frac{11}{12}

Step-by-step explanation:

\frac{7}{4} ÷ \frac{3}{5} = \frac{7}{4} × \frac{5}{3}

To change the ÷ sign to a × sign, you can swap the denominators and numerators of the second fraction.

\frac{7}{4} × \frac{5}{3} = \frac{35}{12}

Multiply directly.

\frac{35}{12} = 2\frac{11}{12}

Change from improper fractions to mixed numbers.

A ball is tossed between three friends. The first toss is 8.6 feet, the second is 5.8 feet, and the third toss is 7.5 feet, whic
algol13

Answer:

The angles are 79.45, 59.02 and 41.53 degrees to the nearest hundredth.

Step-by-step explanation:

We have a triangle with sides of length 8.6, 5.8 and 7.5 feet.

Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:

cos X =  (8.6^2 - 5.8^2 - 7.5^2) / ( -2*5.8*7.5)

=  0.18310

X =  79.45 degrees.

We can now find another angle using the sine rule:

8.6 / sin 79.45 =  7.5/ sin Y

sin Y = (7.5 * sin 79.45) / 8.6

Y = 59.02 degrees

So the third angle = 180 - 79.45 - 59.02

= 41.53 degrees.

The height of a cylinder is 5 centimeters. The diameter of the base of the cylinder is 16 centimeters. Find the lateral surface
soldier1979 [14.2K]

Answer:

Lateral surface area of the cylinder =251.2 cm^2

Step-by-step explanation:

  Lateral surface area of he cylinder = 2*\pi*r*h  i.e area of side surface.

Height(h) = 5 cm

Diameter = 16 cm

radius(r)= 16/2= 8 cm

Lateral surface area of the cylinder = 2*\pi *8*5                        

                                                                         \pi =\frac{22}{7}=3.14

               L.S.A=  2*3.14*8*5

              L.S.A=  251.2 cm^2

The lateral surface area of the cylinder with radius 8 cm and height 5 cm is 251.2 cm^2
