Mathematics
1 answer:
irina1246 [14]3 years ago
5 0

Answer:

9, 13, 17

Step-by-step explanation:

Substitute n = 1, 2, 3 into the n th term formula, that is

a₁ = 4(1) + 5 = 4 + 5 = 9

a₂ = 4(2) + 5 = 8 + 5 = 13

a₃ = 4(3) + 5 = 12 + 5 = 17

Thus the first 3 terms are 9, 13, 17

How do you graph a ratio
valentina_108 [34]
The graphing of a ratio includes one axis representing part A of the ratio and the other axis representing part B of the ratio. for example, if you have 20 defects per 100 parts of a car, the defects would be represented as part a and the total parts would be represented by part b. These graphs show one part on the left hand and the other on the bottom of the graph, and the graphing of each ratio acts a lot like graphing an equation you would normally see.

I need assistance.<br> i'll give a brainiest
svetlana [45]

Answer:

MP =8

Step-by-step explanation:

QR = 1/2 MP

76 -8x = 1/2 (89 - 9x)             Multiply both sides by 2

152 - 16x = 89 - 9x                Subtract 89 from both sides

152-89 - 16x = - 9x                Add 16x to both sides.

63 - 16x +16x = 16x  - 9x

63 =7x                                  Divide by 7

x = 63/7

x = 9

MP = 89 - 9*9

MP = 8

A stained glass window is going to be installed in a semi-circular opening, which is above a 34 inch wide door. If the stained g
Tasya [4]

The area of a full circle would be Area = PI x r^2

The diameter would be the width of the dorr, so the radius would be half that. 34/2 = 17  inches.

Area for a full circle would be 3.14 x 17^2 = 907.46 square inches.

A semi circle is a half circle.

The area would be 907.46 / 2 = 453.73 square inches.

Multiply the area by the cost:

453.73 x 0.95 = 431.04

The answer is C.

tensa zangetsu [6.8K]

Answer:

50

Step-by-step explanation:

The ratio of marked fish to caught fish is 4:10, we need to solve for x in 20:x, since 4 * 5 = 20, 10 * 5 = x so x = 50 fish.
