Think About the Process The circumference of one coin is 8.03 cm. The circumference of another
coin is 0.33 cm smaller. What is the first step to find the diameter of the smaller coin? What is the
22
diameter of the smaller coin? Use for .
7
What is the first step to find the diameter of the smaller coin?
Answer:
First step will be option D.
Diameter of the smaller coin will be 2.45 cm
Step-by-step explanation:
Circumference of one coin = 8.03 cm
Circumference of the smaller coin = Circumference of the larger coin - 0.33
= 8.03 - 0.33
= 7.7 cm
Circumference of the smaller coin = 2πr = 7.7
r = [tex]\frac{7.7}{2\pi }[/tex]
r = [tex]\frac{7.7\times 7}{2\times 22}[/tex]
r = 1.225 cm
Diameter of the smaller coin = 2 × radius of the smaller coin
= 2 × 1.225
= 2.45 cm
Therefore, first step will be option D.
Diameter of the smaller coin will be 2.45 cm
The frequency table represents the results of a survey comparing the average age of household members to the way that they watch non-network television. A 4-column table with 3 rows titled Television Viewing Method. The first column has no label with entries internet, cable, total. The second column is labeled average household age under 40 with entries 54, 81, 135. the third column is labeled average household age 40 or older with entries 23, 92, 115. the fourth column is labeled total with entries 77, 173, 250. Madigan converts the frequency table to a conditional relative frequency table by row. Television Viewing Method A 4-column table with 3 rows titled Television Viewing Method. The first column has no label with entries internet, cable, total. The second column is labeled average household age under 40 with entries W, Y, 0.54. The third column is labeled average household age 40 or older with entries X, Z, 0.46. The fourth column is labeled total with entries 1.0, 1.0, 1.0. Which value should she use for X? Round to the nearest hundredth. 0.09 0.20 0.25 0.30
Answer:
For X they would have to divide the number from the first given chart for average household of the people that are ages 40 or under, which is 23, by the total internet, which is now 77.
Therefore, X = 23/77 = 0.2987, which would round to 0.30

The Stem-and-Leaf Graph shows the distance traveled by Rob's family, in
miles per day, to reach their holiday destination. What is the mean for this
data?
OA) 65 mi. per day
OB) 73 mi. per day
OC) 82 mi. per day
OD) 94 mi. per day
Answer:73
Step-by-step explanation:
The MEAN in math means you add all of the numbers together
60 plus 65 plus 73 plus 82 plus 85 = 365
then you divide how many numbers there are and there is 5 numbers so you divide.
365 divided by 5 equals 73
Answer:
73

14 adults and 20 children attended a piano recital. If two people are selected to receive door prizes at the recital, what is the probability that both will be children? Write your answer as a fraction and a decimal rounded to the nearest hundredth.
Answer: 0.34
Step-by-step explanation:
From the question, 14 adults and 20 children attended a piano recital. This means that there are 14 + 20 = 34 people who attended the paint recital.
If two people are selected to receive door prizes at the recital, the probability of selecting the first child will be 20/34 while the second child will be 19/33. To get the probability of both being children, we have to multiply the fractions
= 20/34 × 19/33
= 380/1122
= 0.34
For f(x) = x^2 and g(x) = (x-5)^2 in which direction and by how many units should f(x) be shifted to obtain g(x)?
A.) up 5 units
B.) down 5 units
C.) left 5 units
D.) right 5 units
Answer:
D
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Thus
(x - 5)² represents a shift of f(x) to the right of 5 units

37.5(3.8-x)+90x=300 please help me
Answer:
I’m just copying his answer which is 3
Step-by-step explanation:
at least I tried
Answer: 3
Step-by-step explanation:
37.5 (3.8-x) + 90x = 300
First, you have to simplify, by using the Distributive Property.
142.5 - 37.5x + 90x = 300
Now, add the like terms
142.5+ 52.5x = 300
Now, isolate the variable, meaning the variable has to be on one side on its own. You would have to subtract 142.5 and move it to the other side
52.5x = 300 - 142.5
52.5x = 157.5
Then, you divide!
[tex]\frac{52.5x}{52.5x}[/tex] = [tex]\frac{157.5}{52.5x}[/tex]

José represents the linear function f(x) = 5x – 7 with words.
Multiply each element in the domain by negative 7 and add 5.
Correct his error.
Answer:
-2
Step-by-step explanation:
The correct statement that Jose is supposed to have written is that multiply each element in the domain by 5 and subtract 7
Given the linear function written by Jose expressed as f(x) = 5x - 7
Note that the expression is in form of a linear equation y = mx + b where:
x is the input value known as the domain
We are to write the function f(x) = 5x - 7 in words.
Let the domain variable be x
5x means that we are to multiply each element in the domain 5
For 5x - 7, we are to multiply each element in the domain by 5 and subtract 7.
The correct statement that Jose is supposed to have written is that multiply each element in the domain by 5 and subtract 7

Please help ASAP! I NEED VERIFIED ANSWER AND EXPLANATION! THIS DEPENDS ON MY GRADE! I WILL BE MARKING BRAINLIEST ANSWER!!
Answer:
[tex]\sqrt{89}[/tex]
Step-by-step explanation:
distance = [tex]\sqrt{(x_{2}- x_{1})^{2} + { (y_{2} - y_{2} } ){^2} }[/tex]
Let:
(x₁ , y₁) = (0 , 5)
(x₂ , y₂) = (8 , 0)
Plug in the corresponding numbers to the corresponding variables:
Remember to follow PEMDAS. Solve the parenthesis first:
distance = [tex]\sqrt{(8- 0)^{2} + { (0 - 5 } ){^2} }[/tex]
distance = [tex]\sqrt{(8)^2 + (-5)^2}[/tex]
Solve for the powers next:
distance = [tex]\sqrt{(8)^2 + (-5)^2}[/tex]
distance = [tex]\sqrt{64 + 25}[/tex]
Simplify:
distance = [tex]\sqrt{64 + 25}[/tex]
distance = [tex]\sqrt{89}[/tex]

Answer: 140 m3
Step-by-step explanation:
Multiply the area of the trapezoid face by the length .
Since the area is 20, you multiply it by 7 to get 140
Answer:
140 m^3
Step-by-step explanation:
This is a prism with a trapezoid base.
The volume if a prism is
V = (area of base) * height
The base is the trapezoid in the front face. The height is the distance between bases which is 7 m.
area of trapezoid = (b1 + b2)h/2
In the area of the trapezoid, h is the height of the trapezoid which is the distance between parallel bases. It is 4 m in this case.
V = (area of base) * (height of trapezoid)
V = (8 m + 2 m)(4 m)/2 * 7 m
V = 20 m^2 * 7 m^2
V = 140 m^3

Step-by-step explanation:
1.
SA and V of 3x4x5 right rectangular prism.
Three pairs of faces, 3×4, 4×5, 3×5, so area
SA = 2(3×4 + 4×5 + 3×5) = 94 sq ft
V = L×W×H = 3×4×5 = 60 cubic ft
Answer: D. SA 94 sq ft, V 60 cu ft
2. Right triangular prism, base legs 3x4, height 7
Two triangular faces, combined area 2×(1/2)×3×4=12, and three rectangular faces, 3x7, 4x7 and 5x7
SA = 12 + 7(3+4+5) = 8(12) = 96
Volume is area of base times height, so (1/2)(3)(4)(7)=42.
Answer: I. SA 96 sq cm, V 42 cu cm
What is the length of the hypotenuse
Answer:
20
Step-by-step explanation:
To find Hypotenuse: Pythagorean Theroem
a^2+ b^2= c^2
The legs are A and B
The side that is directly across from the Right angle is C
12^2 + 16^2 =C^2
144+256=400
400 = c^2
Square root on both sides to get rid of c^2
The square root of 400 is 20
c=20
Answer:
20 feet
Step-by-step explanation:
c = (a² + b²)
c= (12^2 + 16^2)
c= square root (400)
c= 20
