52.38 inch² & 261.90 inch²
Step-by-step explanation:Here we need to find the area of the sector . So according to formula we know the area of sector as ,
[tex]\boxed {\sf Area_{(sector)}= \dfrac{\theta}{360}\times \pi r^2 }[/tex]
Here we can see that the central angle subtended by the arc is 60° and the radius of the circle is 10 inches . So the required area would be ,
=> Area = ∅/ 360° × π r²
=> Area = 60°/360° × 22/7 × (10in.)²
=> Area = 1/6 * 22/7 * 100 in²
=> Area = 52 .380 in²
★ Hence the area of the red sector is 52.38 inch²._________________________________
Now let's find out the area of blue sector .The angle subtended by the arc will be (360-60)°=300° .
=> Area = 300/360 × 22/7 × 100 in²
=> Area = 261. 90 in²
★ Hence the area of blue sector is 261.90 inch².[tex]\boxed{\red{\sf Area _{(red \ sector )} = 52.38 in^2 }}[/tex]
[tex]\boxed{\blue{\sf Area _{(blue \ sector )} = 261.90 in^2 }}[/tex]

Answers
Answer:
9x² + y² + 64 - 6xy - 16y - 48x
= 9x² - 6xy - 48x + y² - 16y + 64
= 9x² - 6x(y - 8) + y² - 2.8y + 8²
= (3x)² - 6x(y - 8) + (y - 8)²
= [3x - (y - 8)]²
= (3x - y + 8)²

What are expressions for the length, width, and height?
Answers
Answer:
3x, 2x + 5, and x - 3
Step-by-step explanation:
Since the given figure is a 3-dimensional shape, we know that there must be three zeroes.
Our equation is:
6x³ - 3x² - 45x
First, we can factor out an x:
x (6x² - 3x - 45)
From here, we can see that by factoring out a 3:
3x (2x² - x - 15)
Now, after completing the square and factoring:
3x (2x + 5) (x - 3)
These are our three expressions.

What is a, the initial amount, for the function: f(x) = 300(1.16)*?
Answers
====================================================
Explanation:
One general template of exponential functions is
f(x) = a*(b)^x
The 'a' is the initial amount, which in this case is a = 300
----------------------
Extra info:
The b is the base of the exponential, which is b = 1.16
The value of b is helpful to determine if you have exponential growth or decay, and how much of either. Because b = 1.16 is greater than 1, it indicates exponential growth. The rate of growth is found by solving 1+r = 1.16 to get r = 0.16, which leads to 16% growth.
silvia compro la misma licuadora que daniela, que costaba $355.5, pero como abonó con tarjeta de credito, le recargaron un 16%, ¿cuanto pago silvia?
Answers
Answer:
Costo final= $412.38
Step-by-step explanation:
Dada la siguiente información:
Costo inicial= $355.5
Recargo de la tarjeta= 16% = 0.16
Para calcular el costo final que debe pagar Silvia, debemos usar la siguiente información:
Costo final= costo inicial*(1 + recargo)
Costo final= 355.5*1.16
Costo final= $412.38
A road roller with a 55-inch
diameter is traveling at
3 miles per hour. How many
revolutions per minute is
the roller turning? Round
your answer to the
nearest tenth
Answers
Answer:
18.34times
Step-by-step explanation:
the explanation is given in the pictures...
The road roller is turning at the rate of [tex]18.3rev/minute[/tex]
To get our answer, first note that
[tex]speed=\dfrac{distance}{time}[/tex]
since the distance travelled by the road roller can be gotten by
[tex]distance= circumference\times revolutions[/tex]
our speed formula can be expressed as
[tex]speed=\dfrac{circumference\times revolutions}{time}[/tex]
making the number of revolutions the subject of the formula, we get
[tex]revolutions=\dfrac{speed \times time}{circumference}[/tex]
carrying out the following substitutions
[tex]speed=3miles/hour=\frac{3\times63360}{60}inches/minute=3168inches/minute\\time=1minute\\circumference=2\times3.14\times\frac{55}{2}=172.7inches[/tex]
we can now calculate the number of revolutions
[tex]revolutions=\dfrac{speed\times time}{circumference}\\\\=\dfrac{3168\times 1}{172.7}\approx18.3rev/minute\text{ (to the nearest tenth)}\\\\[/tex]

What is perimeter of the semi circle?
Answers
Answer:
54.22 mm
Step-by-step explanation:
Find the circumference of the circle and then divide it by 2.
We start with the formula for the circumference for the circle:
C = 2πr
To find r, divide 22 by 2:
22/2=11
Now find the cicumference:
C = 2πr = 2(3.14)(11) = 108.46 mm
NOW, to find the perimeter of the semicircle, divide the circumference by 2:
108.46/2 = 54.22 mm
