Step-by-step explanation:

Just some division

Answer:

neither

Step-by-step explanation:

The side AC of the triangle is included between angles A and C.

An included side is a side that is in between two angles in a triangle, where the rays of the angles overlap.

Given is a triangle, we need to determine the angles which includes the side AC,

Since angle A and angle C forms side AC, AC is included between: A. ∠A and ∠C.

Thus, in triangle ABC, side AC lies in between angle A and angle C.

Therefore, since angle A and angle C forms side AC, AC is included between ∠A and ∠C.

Hence, the side AC of the triangle is included between angles A and C.

3^2 + 10^2 = 109

square root of 109 = 10.4403065089

Answer:

x=10.44

Step-by-step explanation:

10^2+3^2=x^2

100+9=x^2

109=x^2

10.44030651=x

y = -2(x + 1)² + 3

y = -2(x² + 2x + 1) + 3

y = -2x² - 4x - 2 + 3

y = -2x² - 4x + 1

Answer:

4x + y = -1

just simplify then re-write

Answer:

4/5

Step-by-step explanation:

Played 20 games. Won 16. Both numbers have a 4 in common. divide 16 by 4.. which is 4. Divide 20 by 4... which is 5. That means Tim won 4/5 of the games played.

Answer :4/5

Step-by-step explanation:

Because we write  16/20 and simplify it by 4 and thats the simplest form

Answer:

1. x =-4 (-4,27)

x =0 (0,3)

x = 2 (2 , -9)

2. x = -1 (-1 , 3)

x = -2 (-2 , 2)

x = -3 ( -3, 1)

3. x = -3 (-3 , 13)

x = 1 (1 , 1)

x = -2 ( -2, 10)

4. x =2  (2 , 24)

x = 3 (3 , 30)

x = -2 (-2 , 0)

5.x = -3 (-3 , -2)

x = 2 (2 ,-12 )

x =4  (4 , -16)

6. x = -1 (-1 , -2)

x = 0 (0 , 2)

x = 2 (2 , 10)

7. x = -2 (-2 , -10)

x = 0 (0 , -14)

x = 3 (3 , -20)

Fraction: x = 2197/204

Decimal: 10.76960

Step-by-step explanation:

Switch Sides: 2.03 +2.04x + 1=25

Group Like Terms: 2.04x + 2.03 + 1 =25

Add The Numbers 2.03 + 1 = 3.03: 2.04x + 3.03 = 25

Multiply Both Sides By 100: 2.04 * 100 + 3.03 * 100 = 25 * 100

Clarify: 204x+303=2500

Subtract 303 From Both Sides: 204x + 303 - 303=  2500 - 303

Divide Both Sides By 204: 204x/ 204, 2197/204

Simplify: x = 2197/204

Answer:

C

Step-by-step explanation:

Radius: 12 / 2 = 6 m

Area: 6^2 x pi = 113 m^2

Answer:

c

Step-by-step explanation:

area = π · r²

to change the diameter to radius you just divide by 2

12/2=6 so the radius is 6

then we just plug 6 into r for the circle are formula

6²=36

36x3.14=113.04 so her best answer choice is c

Answer:

B) 114.511m^3

Step-by-step explanation:

Formula of a cylinder is πr^2 x h

r = radius (half of diameter)

h = height

Since it is 3/4 full you only do 3/4 of the height so- 0.75 x 9.60 which equals 7.2

Half of the diameter is 2.25. 2.25^2 = 5.0625.

The volume of the cylinder = 5.0625π x 7.2

By solving this, you will get approximately 114.511 m^3 as your answer.

Answer:

b would be 6xy

c would be 6xy as well

Step-by-step explanation:

Not really sure how to explain it, I just know it

Answer:

b) 6xy

c) 6xy

Step-by-step explanation:

b) 6 × x × y

Since there are no like terms, just straight away remove the multiplication signs. So the answer is:

= 6xy  

c) 2 × x × 3 × y

2 and 3 are like terms since they are both natural numbers (positive integers), you can multiply 2 with 3. The answer will be:

= 6xy

Answer:

305.5 sq inches

Step-by-step explanation:

A (trapezoid) = 1/2·h·(sum of bases)

A = 1/2(17)(8 + 23)

A = 8.5(31)

A = 263.5

A(triangle) = 1/2·b·h

A = 1/2·(6)·(17-3)

A = 3(14)

A = 42

Total Area = 263.5 + 42.0 = 305.5 sq in
