Answer:
615.75216....
Step-by-step explanation:
The formula is A = π * (ø/ 2)^2
A = Circle area
π = Pi = 3.14
ø = Circle diameter
A= 3.14 (28/2)^2
Answer:
Area = 615.44 inches
Step-by-step explanation:
Diameter = 2 * radius
28 = 2 * radius
Divide both sides of the equation by 2
14 = radius
Find area
A = π r²
A = 3.14 (14)²
A = 3.14 (196)
A = 615.44

A medical clinic is reducing the number of incoming patients by giving vaccines before flu season. During week 5 of flu season, the clinic saw 75 patients. In week 10 of flu season, the clinic saw 50 patients. Assume the reduction in the number of patients each week is linear. Write an equation in function form to show the number of patients seen each week at the clinic.
A.fx=5x+100
B.fx=-5x+100
C.fx=25+75
D.fx=-25+75
Answer:
85 flu patients Per week so A
Step-by-step explanation:
Final answer:
Using the two given points during the flu season, we calculate the slope of the reduction in patients per week and use one of the points to find the y-intercept. The resulting linear equation representing the number of patients seen each week at the clinic is f(x) = -5x + 100, which corresponds to option B.
Explanation:
To find the function that represents the number of patients seen each week during flu season at a medical clinic, we can use the two data points provided: In week 5, there were 75 patients (point 1: (5, 75)), and in week 10, there were 50 patients (point 2: (10, 50)). The goal is to find a linear equation of the form f(x) = mx + b, where m is the slope of the line and b is the y-intercept.
First, we find the slope (m) using the formula:
m = (Y2 - Y1) / (X2 - X1)
Substituting the given values, we get:
m = (50 - 75) / (10 - 5) = -25 / 5 = -5
Now we use one of the points to find the y-intercept (b).
Using point (5, 75):
75 = (-5)(5) + b
75 = -25 + b
b = 75 + 25
b = 100
So the equation of this function in function form is:
f(x) = -5x + 100
Therefore, the correct option is B. f(x) = -5x + 100.

What is Relationship between Radius and Diameter?We all know that a circle's radius is the distance a point on the circle's circumference travels from its centre.
The circle's diameter is a straight line that passes through its centre and has its endpoints on the circle.
Radius is therefore equal to half of diameter.
From the figure we have,
Diameter = 6.9 unit
Now, using the relation
Diameter = 2 x radius
6.9 = 2 x radius
radius = 6.9/ 2
radius = 3.45 unit

57 28 19 19 26 54 88 65 13 10 18 50 29 Calculate the average (arithmetic mean) of the list of numbers shown in the table. (rounded to the nearest tenth)
Answer:
36.6 or 36.61
Step-by-step explanation:
the first thing you want to do is add all your numbers together.
57+28+19+19+26+54+88+65+13+10+18+50+29
this would equal 476
the second thing you do is divide your total by the amount of numbers in your equation:
476/13
which would equal:
36.6153846
Lastly, you round to the tenth place, if the number in the second place after the decimal is under 5, the number before stays the same(if its above 5 you would round up). Since the second number after the decimal is under 5 it stays the same
your answer would be 36.6 or 36.61.
I hope this helped! sorry if i messed up its been a while.
Final answer:
To find the average of a list of numbers, add all the numbers and divide by the total count. In this case, the average of the numbers provided is 36.6 when rounded to the nearest tenth.
Explanation:
Given numbers = 57 28 19 19 26 54 88 65 13 10 18 50 29
To calculate the average of a list of numbers, you need to add all the numbers together and then divide by the total count of numbers.
Add all the numbers in the list: 57 + 28 + 19 + 19 + 26 + 54 + 88 + 65 + 13 + 10 + 18 + 50 + 29 = 476
Divide the sum by the total count of numbers in the list: 476 ÷ 13 = 36.6
Rounded to the nearest tenth, the average of the list of numbers is 36.6

Estimate the area of the circle. Round to the nearest whole number. A) 3 square units B) 6 square units C) 9 square units D) 12 square units
Answer:
3 square units branliest pls
Step-by-step explanation:
The correct answer is option A. The estimated area of the circle is 3 square units.
To estimate the area of a circle, we use the formula for the area of a circle:
[tex]\[ A = \pi r^2 \][/tex]
where [tex]\( r \)[/tex] is the radius of the circle. Given that the diameter of the circle is 2 units, we can find the radius by dividing the diameter by 2:
[tex]\[ r = \frac{d}{2} = \frac{2}{2} = 1 \text{ unit} \][/tex]
Now, we substitute the radius into the area formula:
[tex]\[ A = \pi (1)^2 = \pi \][/tex]
Using the value of [tex]\(\pi \approx 3.14\)[/tex], we get:
[tex]\[ A \approx 3.14 \][/tex]
Rounding 3.14 to the nearest whole number, we get:
[tex]\[ A \approx 3 \][/tex].
The complete question is:
Estimate the area of the circle, given the diameter as 2 unit. Round to the nearest whole number.

A pile of earth removed from an excavation is a cone measuring 9 ft high and 24 ft across its base. How many trips will it take to haul away the earth using a dump truck with a capacity of 9 cubic yards?
Answer: It would take 6 trips
Step-by-step explanation: The pile of earth has formed into a cone with the following dimensions, height is 9 feet and base diameter is 24 feet across.
However the haulage truck has its capacity measured in yards, and so we use a standard rate of conversion of yards to feet and vice versa. The standard rate is;
1 Yard = 3 Feet
Hence, the height of the pile of earth an now be given as;
h yards = 9/3
h yards = 3
height = 3 yards
Similarly, the the base of the pile of earth can be calculated as;
(Note that the radius is derived as diameter divided by 2, that is 24/2)
r yards = 12/3
r yards = 4
radius = 4 yards
The volume of a cone is given as;
Volume = πr²h/3
Volume = 3.14 x 4² x (3/3)
Volume = 3.14 x 16
Volume = 50.24 cubic yards
For a haulage truck that can haul 9 cubic yards per trip, the total number of trips required to haul the entire volume of dirt is given as follows;
No of trips = 50.24 ÷ 9
No of trips = 5.5822
No of trips ≈ 6
Therefore it would take the truck 6 trips to haul the entire pile of earth.
Answer:
6 trips

Help two helpless triangles?
Answer:
see below
Step-by-step explanation:
Angle ACE = DCE since they are vertical angles
Angle A = Angle E parallel lines cut by a transversal form congruent alternate interior angles
Angle B = Angle D parallel lines cut by a transversal form congruent alternate interior angles
When all three angles are equal, the triangles are similar.
We can use ratios to find DE
DE CE
------- = ----------
AB AC
DE 8
------- = ----------
12 10
Using cross products
10 DE = 8*12
10 DE = 96
Divide by 10
DE = 9.6
Answer:
1) they are similar by AAA postulate
2) 9.6 cm
Explanation:
Triangles CAB and CED are similar
because:
1) both have the same angle C
(vertically opposite angles)
2) Angle A = Angle E
(alternate angles)
3) Angle B = Angle D
(alternate angles)
CA/CE = AB/ED
10/8 = 12/DE
DE = 12 × 8/10
DE = 9.6 cm

(The answer is not 8.6)
Answer:
I believe the answer is, 11.75.
-Hope this helps!
Step-by-step explanation:
To find the mean, you must add up all your data and divide it by how many people there are. So, all the numbers added together is, 82. Since there are seven kids, you would divide 82 by 7. Which equals, 11.75: (Simplified).

A. Elise should subtract 8 from both sides.
B. Elise should divide both sides by 8.
C. Elise should multiply both sides by 8.
D. Elise should subtract 12.5 from both sides.
Answer:
C. Elise should multiply both sides by 8.
Step-by-step explanation:
We need to undo what is being done to x
We are dividing x by 8, so to undo it we do the opposite.
The opposite of dividing is multiplication.
We multiply each side of the equation by 8
Jeff has $20. He spent 1/8 of his money on lunch and 2/5 of his money at the movies. How much money does Jeff have left?
A. $5.50
B. $7.00
C. $8.25
D. $9.50
Answer:
D. $9.50
Step-by-step explanation:
In total, Jeff spends 21/40 of his money. (1/8+2/5=21/40)
He has 19/40 left.
19/40*20=380/40=9.5
First, let's put 2/5 and 1/8 into similar fractions, in that they have the same denominator.
2/5 = 16/40
1/8 = 5/40
Then, we'll add the fractions together.
16/40 + 5/40 = 21/40
So, Jeff spent 21/40 of his money. We can set up a proportion to find the amount that Jeff spent.
x/20 = 21/40
420 = 40x
x = 10.50
Finally, we'll subtract the amount that Jeff spent from the original amount.
20 - 10.50 = 9.50
Jeff has D. $9.50 left.
