Answers
Answer:
201.4Step-by-step explanation:
The triangle's base is the diameter and height is the radius of circle.
The shaded area is:
A = πr² - 1/2bhA = 3.14*9.7² - 1/2(2*9.7)(9.7) = 201.4Answer:
Solution given:
base for triangle=2r=2*9.7=19.4
height [h]=9.7
area of triangle=½base *height=½(19.4×9.7)=94.09units²
area of circle=πr²=3.14×9.7²=295.4456units²
Now
Area of shaded region=295.4456-94.09=201.3536units²

When theres a triangle with a right angle you need to make in a rectangle and divide it by 2
Answer:
In order to find the area of a triangle, you need to use the formula [tex]\frac{1}{2} bh[/tex]. Substitute the known values into the formula and solve the equation.
Step-by-step explanation:
The formula to calculate the area of a triangle is [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] represents the length of the triangle's base, and [tex]h[/tex] represents the length of the triangle's height. Since [tex]b[/tex] and [tex]h[/tex] are variables that have different values in regards to different triangles, that means you should substitute the known/given values of each variable into the formula and solve the equation.

A cuboid has 4 rectangular faces and 2 square faces. Each rectangular face measures 8 cm by 6 cm. Find the two possible values for the surface area of the cuboid.
pls give me answer with steps
Answers
Answer:
320 cm² or 264 cm²
Step-by-step explanation:
first, the rectangular face area is 4 faces at 8 x 6 = 192 cm²
the 2 square faces will be either 8 x 8 or 6 x 6.
If 8 x 8, then the SA will be 192 + (2 x 8 x 8 ) = 320 cm²
If 6 x 6, then the SA will be 192 + (2 x 6 x 6 ) = 264 cm²

(C) A double blind experiment.
Ablocked design experiment.
Answers
Answer:
(B) An uncontrolled experiment.
Step-by-step explanation:
In the case of an uncontrolled experiment here all participants are provided the similar treatment and there should be no comparison oppose to any group i.e. controlled
Since in the given situation, there are similar diets are provided to 20 volunteers and it can be that the cholesterol level is decreased after particular time period,
Hence, it is an uncontrolled experiment.
Thus, option B is correct.
Steps for solving 5(2x - 8) = 20 are shown. 5(2x-8)= 20 10x - 40 = 20 10x - 40+ 40 = 20 + 40 10x = 60 10x 60 10 10 x = 6 Original Equation Which of these is not part of the solution process?
Answers
Answer:
(d) Using the commutative property
Step-by-step explanation:
Given
The above steps
Required
Which is not part of the process
We have:
[tex]5(2x-8)= 20[/tex]
[tex]10x - 40 = 20[/tex]
[tex]10x - 40+ 40 = 20 + 40[/tex]
[tex]10x = 60[/tex]
[tex]\frac{10x}{10} = \frac{60}{10}[/tex]
[tex]x = 6[/tex]
Comparing the above steps with the given list of options, we can see that the commutative property is not applied at all.
Other properties are:
[tex]5(2x-8)= 20[/tex] ---- Distributive
[tex]10x - 40+ 40 = 20 + 40[/tex] ---- Like terms
[tex]\frac{10x}{10} = \frac{60}{10}[/tex] --- Isolating the variable

Answers
Answer:
Step-by-step explanation:
The x-coordinate of the point that divides the line segment will be -2. Then the correct option is B.
What is the section of the line?Let A (x₁, y₁) and B (x₂, y₂) be a line segment. Then the point P (x, y) divides the line segment in the ratio of m:n. Then we have
x = (mx₂ + nx₁) / (m + n)
y = (my₂ + ny₁) / (m + n)
The two endpoints are (-6, -2) and (8, -9). And m: n = 2: 5. Then the value of the x-coordinate is calculated as,
x = (2 · 8 + 5 · -6) / (2 + 5)
x = (16 - 30) / (7)
x = - 14 / 7
x = - 2
The x-coordinate of the point that divides the line segment will be -2. Then the correct option is B.

The mean emission, μ, of all engines of this type must be approximately 20 parts per million of carbon. If it is higher than that, they will have to redesign parts of the engine. Ten engines are manufactured for testing purposes and the emission level of each is determined.

the mean of "n" numbers is "x" . if one more is added the mean is "y" . write an algebraic expression for the value of the number added?
Answers
Answer:
yn +y -xn
Step-by-step explanation:
Mean= sum of numbers ÷number of numbers
x= sum of n numbers ÷n
Multiply both sides by n:
xn= sum of n numbers
sum of n numbers= xn -----(1)
Let the number added be a.
After a has been added,
y= (sum of n numbers +a) ÷(n+1)
Multiply both sides by (n +1):
y(n +1)= sum of n numbers +a
sum of n numbers= y(n +1) -a -----(2)
Substitute (1) into (2):
xn= y(n +1) -a
Expand:
xn= yn +y -a
a= yn +y -xn
Let's check!
Let the numbers be 1, 2, 3 and 4.
mean, x= 10 ÷4= 2.5
n= 4
Let the new number added, a, be 7.
a= 7
mean, y= 17 ÷5= 3.4
a= yn +y -xn
a= 3.4(4) +3.4 -2.5(4)
a= 7
Thus, the expression is true.
