The number 4, 207 in expanded form is (4 × 1000) + (2 × 100) + (0 × 10) + (7 × 1) which is correct option(A)
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculations
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation : Divides left hand operand by right hand operand
For example 4/2 = 2
Given the number is 4, 207
The number is the addition of 4000, 200 and 7
So, 4207 = 4000 + 200 + 7
4000 is the product of 4 and 1000,
200 is the product of 2 and 100,
4207 = (4 × 1000) + (2 × 100) + (0 × 10) + (7 × 1)
Hence, It is the expanded form of number 4,207.

What is the average rate of change from x =π/2 to x = 2π
Answer:
average is equal to sum of x1 and x2
x1=||/2 and x2=2||
so,
average=||/2 + 2|| the whole thing divide by2
||= 22/7
then,
22/7÷2=22/14
2×22/7=44/7
(22/7+44/7)/2
66/7÷2
66/14=33/7
therefore average is 33/7

please solve for x and y in the diagrams below:
x = 10°
y = 112°
Step-by-step explanation:
From the definition of supplementary angles,
68° + y = 180° ---> y = 180° - 68° = 112°
From the definition of vertical angles,
(4x - 2) + 30 = 68
4x - 2 = 68 - 30 = 38
4x = 40
x = 10
Answer:
y+68=180(being straight angle)
y=180-68
y=112
4x-2=30
4x=28
x=7

Step-by-step explanation:
Classify the conic section and write the equation in standard form:
- 2x^2+ 24x + y - 70 = 0
Parabola: (y – 6)^2 = 5/4(x +1)
Hyperbola: (y+2)^2/4 - (x-3)^2/4 = 1
Parabola: (0 - 6)^2= 1/2(y + 2)

How much of a circle does a 100-degree angle turn through? The answers for the question are 1, 100/180, 50/360, and 100/360. Which one is right?
Answer:
D
Step-by-step explanation:
The answer is D because a circle has at least a 360 degree and a 180 is a half circle.

A point is chosen at random in the circle.
What percent of the time will the point be in
the square?
Round to the nearest tenth of a percent.
1 in.
[ ? ]%
Enter
Answer:
78.5%
Step-by-step explanation:
the percent of time the point will land in the square can be determined by dividing the area of the square by the area of the circle
A(circle) = 3.14(1)²
A(circle) = 3.14
A(square) = side squared
if radius of square is 1 inch then each side is 2 inches
A(square) = 2²
A(square) = 4 inches
3.14/4 = 78.5%
The area of a rectangle is 70 square feet. The length is 10 feet. Find the width [W] of the rectangle
pls help
W = ___ ____
Answer:
35
Step-by-step explanation:
The answer might be 7 i don't know
Answer:
w = 7 feet
Step-by-step explanation:
The area of the rectangle, 70 ft², is equal to the length, 10 ft, times the width, w.
So, to find w, we can divide the area by the length.
w = 70 / 10
w = 7
The width is equal to 7 feet.
We can check this by multiplying the given length by the width that we've calculated to see if the area is equal to 70 feet².
10 · 7 = A
70 = A
Because the area we found is equal to the given area, our calculations are correct.
I hope this helps ^^

Find the lateral and surface area of the figure.
Answer:
A.
Lateral area (LA) = 324 cm²
Surface area = 432 cm²
Step-by-step explanation:
✔️Lateral area of the triangular prism = perimeter of the base (P) × height of prism (L)
Perimeter (P) = 9 + 12 + 15
Perimeter (P) = 36 cm
height of prism (L) = 9 cm
Lateral area (LA) = 36 × 9 = 324 cm²
✔️Surface area = bh + LA
b = 9 cm
h = 12 cm
LA = 324 cm²
Surface area = 9*12 + 324
= 108 + 324
Surface area = 432 cm²
idhi has cut out a semi-circular piece from a plastic sheet and divided it into 8 equal parts as shown: She wants to use this to measure angles. Which of the following angles will she be able to measure accurately using this semi-circular piece?
a. 30⁰
b. 45⁰
c. 60⁰
d. 100⁰
Answer:
[tex]c)\ 45^\circ[/tex]
Step-by-step explanation:
Given
A semicircle divided into 8 parts
Required
Angle that can be measured with the piece
First, we calculate the minimum angle that can be calculated.
[tex]\theta =\frac{Semi\ circle}{8}[/tex]
[tex]Semicircle = 180^\circ[/tex]
So, we have:
[tex]\theta =\frac{180^\circ}{8}[/tex]
[tex]\theta =22.5^\circ[/tex]
This implies that all angles that can be measured using the piece must be a multiple of 22.5 not greater than 180 degrees (i.e. not greater than the semicircle)
So, we have:
[tex]\theta =22.5^\circ,\ 45^\circ,\ 67.5^\circ,\ 90^\circ,\ 112.5^\circ,\ 135^\circ,\ 157.5^\circ,\ 180^\circ[/tex]
From the list of options, only 45 degrees appear in the possible values of [tex]\theta[/tex]
Hence:
[tex]\theta = 45^\circ[/tex]

To estimate the proportion of brand-name lightbulbs that are defective, a simple random sample of 400 brand-name lightbulbs is taken and 44 are found to be defective. Let X represent the number of brand-name lightbulbs that are defective in a sample of 400, and let PXrepresent the proportion of all brand-name lightbulbs that are defective. It is reasonable to assume that X is a binomial random variable.
Requried:
One condition for obtaining an interval estimate for Px is that the distribution of Px is approximately normal. Is it reasonable to assume that the condition is met?
Answer:
X is a binomial random variable
Then the condition is met
Step-by-step explanation:
Sample size n₁ = 400
X represents the number of brand-name lightbulbs)
P(X) = 44/400
P(X) = 0,11
X is a binomial random variable it only could be either no defective or defective ( only two conditions or values).
To make use of the condition of approximation of binomial distribution to a normal distribution it is required that the products:
p*n = 0,11*400 = 44 and q = 1 - 0,11 q = 0,89
q*n = 0,89 * 400 = 356
both p*n q*n are greater than 5.
Then the condition is met
