Answer:

A. 41

B. 1,590

C. .1

Step-by-step explanation:

A.

the equation is l*w=A

9.2*4.5=A

41.4=A

rounded it would be 41

B.

the equation is pi*r^2=A

3.14*22.5^2=A

3.14*506.25=A

1,589.6=A

^round this up to get 1,590

C.

what I did was use a*b/2 to find one side then add the other side (less complicated in my opinion)

.5*.2/2=A

.1/2=A

.05=A

.05+.05=0.1

Answer:

\text{a. }41.4\:\mathrm{m^2},\\\text{b. }1590.4\:\mathrm{cm^2},\\\text{c. }0.1\:\mathrm{m^2}

Step-by-step explanation:

<u>Part A</u>:

The figure implies a rectangle. The area of a rectangle with base b and height h is given by A=bh.

What we're given:

  • b of 9.2
  • h of 4.5

Therefore, the area of the rectangle is 9.2\cdot 4.5=\boxed{41.4\:\mathrm{m^2}}

<u>Part B</u>:

The figure shows a circle. The area of a circle with radius r is given by A=r^2\pi. In the figure, the diameter is marked as 45 cm. To find the radius, we must divided this by 2, because by definition, the radius if half the diameter. Therefore, r=\frac{45}{2}=22.5\:\mathrm{cm} and the area of this circle, rounded to the nearest tenth, is 22.5^2\pi=1590.43128088\approx \boxed{1590.4\:\mathrm{cm^2}}

<u>Part C</u>:

The figure shows a triangle (polygon with three sides). The area of a triangle with base b and height h is given by A=\frac{1}{2}bh.

What we're given:

  • b of 0.4
  • h of 0.5

Substituting given values, we get:

A=\frac{1}{2}\cdot 0.4\cdot 0.5=\boxed{0.1\:\mathrm{m^2}}

Claudia tiene 3/6 de un
KengaRu [80]

En este problema simplemente tenemos que usar la suma de fracciones.

Veremos que entre ambos tienen un frasco entero de miel.

Sabemos que Clauida tiene 3/6 de un frasco de miel, y el hermano tiene 9/18 de un frasco de miel.

En total, entre ambos, tienen:

3/6 + 9/18

Para poder realizar esta suma tenemos que tener el mismo denominador en ambas fracciones, asi que podemos simplificar.

en 9/18 si dividimos numerador y denominador por 9 obtenemos:

9/18 = 1/2

en 3/6 si dividimos numerador y denominador por 3 obtenemos:

3/6 = 1/2

Así:

3/6 + 9/18 = 1/2 + 1/2 = 1

Entre ambos tienen un frasco entero de miel.

Witch set of orderd pairs contains only points that are on the graph of the function y=12-3x
anygoal [31]
You can try then by plotting the points in. 
The answer is C

Make sure by plotting in the points, lets take (-5,27)
y = 12 -3(-5)
y = 12 + 15
y = 27
27 = 27
This is correct 

Lets try (-1,15)
y = 12 -3(-1)
y = 12 + 3 
y = 15 
15 = 15
This is correct 

Lets try (8,-12)
y = 12 -3(8)
y = 12 - 24 
y = -12 
-12 = -12
This is correct too. 

The correct ordered pairs are <span>C(-5,27),(-1,15),(8,-12)</span>
