Solve. 8+2=16106. 5+4=2091. 9+6=54153. 7+5=35122. 20+3=602317. 30+1=303129. 18+4=722214. 10+5=??

Sergio [31]

answer:

505155

step-by-step explanation:

multiply, add, and subtract the first two numbers of the equation in that order to get the final number

8 + 2 = 16106: 8 x 2 = 16, 8 + 2 = 10, 8 - 2 = 6 to get the number 16106

5 + 4 = 2091: 5 x 4 = 20, 5 + 4 = 9, and 5 - 4 = 1 to get the number 2091

9 + 6 = 54153: 9 x 6 = 54, 9 + 6 = 15, and 9 - 6 = 3 to get the number 54153

7 + 5 = 35122: 7 x 5 = 35, 7 + 5 = 12, and 7 - 5 = 2 to get the number 35122

20 + 3 = 602317: 20 x 3 = 60, 20 + 3 = 23, and 20 - 3 = 17 to get the number 602317

30 + 1 = 303129: 30 x 1 = 30, 30 + 1 = 31, and 30 - 1 = 29 to get the number 303129

18 + 4 = 722214: 18 x 4 = 72, 18 + 4 = 22, and 18 - 4 = 14 to get the number 722214

10 + 5 = 505155: 10 x 5 = 50, 10 + 5 = 15, and 10 - 5 = 5 to get the number 505155

What is the area of the composite figure? (use 3.14 for pi). Explain how you arrived at your answer. Please round to the nearest

maksim [4K]

The area of the given diagram is 29.817 square centimeters. The given diagram is combination of rectangle and semi circle.

Step-by-step explanation:

The given is,

Given diagram is combination of Rectangle and Semi circle.

Step:1

Res the attachment,

Area of given diagram = Area of A + Area of B..............(1)

Step:2

For A,

The A section in the given diagram is semi circle,

Diameter of semi circle = Total distance - ( 2+3)

( ∵ 2, 3 are top distance in the given diagram)

$= 10 - 5$

Diameter, d = 5 cm

Radius, $r = \frac{d}{2}$

$r = \frac{5}{2}$

r = 2.5 cm

Area, $A_{A} = \frac {\pi r^{2} }{2}$ ........................(2)

$A_{A} = \frac {\pi (2.5)^{2} }{2}$

$= \frac {\pi ( 6.25) }{2}$

$= \frac{19.63}{2}$

$A_{A} = 9.8174 cm^{2}$

Step:3

For B,

Area of rectangle is,

$A_{B} =lb$ .....................(3)

Where, l - Length = 10 cm

b - Width = 2 cm

Equation (3) become,

$= (10)(2)$

$= 20$

Area of B, $A_{B}$ = 20 $cm^{2}$

Step:4

From the equation (1),

Area of given diagram = 20+ 9.81747

Area = 29.817 square centimeters

Result:

The area of the given diagram is 29.817 square centimeters. The given diagram is combination of rectangle and semi circle.

Is the point (2,8) a solution of the equation y = 13x + 12? O Yes O No

vovikov84 [41]

Answer:

O No

Explanation:

Given equation: y = 13x + 12

To check if (2, 8) is a solution of the given equation.

Substitute x and y value in equation and check if it is true.

$\rightarrow y = 13x+12$

(x, y) = (2, 8)

$\rightarrow 8 = 13(2)+12$

simplify

$\rightarrow 8 = 38$

This following statement is false and hence (2, 8) is not a solution.
