Answer:
Angle BAC = 62.35
Step-by-step explanation:
Here, we want to get the angle marked BAC
From the diagram, we have the angle ABC as 90
This is because angle at the center is twice the angle at the circumference
Furthermore, using the arc angle relationship;
angle ACB is half arc AB
so ACB angle is 55.3/2 = 27.65
mathematically;
Angle BAC + 27.65 + 90 = 180
This is because sum of angles in a triangle is 180
Thus;
angle BAC = 180-90 - 27.65
angle BAC = 62.35

A Circular pool has diameter of 24 feet what's the area of the cover - 452.16 square feet - 75.36 square feet - 150.72 square feet - 1,808.64 square feet
Answers
Answer: 452.16 square feet
Step-by-step explanation:
The formula that is used to calculate the area of a circle is given as:
= πr²
where π = 3.14
r = Diameter/2 = 24/2 = 12
Area = πr²
= 3.14 × 12²
= 3.14 × 144
= 452.16 feet²
Therefore, the answer is 452.16 square feet.
Find the total package price from each store and then calculate how much you"lol save if you purchase the less expensive package
Answers
Complete Question:
You're planning to buy a new computer, monitor, and printer for your office. You've received the following prices from two stores:
Store 1 Store 2
Computer: 2,500 Computer: 2,350
Monitor: 595 Monitor: 435
Printer: 398 Printer: 349
Find the total package price from each store and then calculate how much you'll save if you purchase the less expensive package.
Answer:
[tex]Total = 3493[/tex] --- Store 1
[tex]Total = 3134[/tex] --- Store 2
[tex]Saved = 359[/tex]
Step-by-step explanation:
From store 1, the total cost is:
[tex]Total = 2500 + 595 + 398[/tex]
[tex]Total = 3493[/tex]
For store 2, the total cost is
[tex]Total = 2350 + 435 + 349[/tex]
[tex]Total = 3134[/tex]
By comparison: It is cheaper to buy from store 2
Because [tex]3134 < 3493[/tex]
Amount saved is calculated by subtracting the cheaper cost from the expensive cost:
i.e.
[tex]Saved = 3493 - 3134[/tex]
[tex]Saved = 359[/tex]
HELP ASAP. please show work. the plane of a room in the picture. the scale is 2 inches: 6 feet. what is the actual length, width , and area?
Answers
Answer:
Actual Length: 27 feet - Actual Width: 15 feet - Actual Area: 405 feet
Step-by-step explanation:
First, to find the length, you have to divide 9 by 2 to get 4.5 and then multiply it by 6 to get the actual amount of feet. Then you divide 5 by 2 and multiply the quotient by 6 to get the actual width. Then, you take the actual length (27 feet) and multiply it by the actual width (15 feet) and you get an area of 405 feet

A customer pay 72$ for 18 sandwiches. If each sandwich cost the same amount , what is the cost per sandwich, in dollars?
Answers
Answer:
Each sandwich costs 4$.
Step-by-step explanation:
To find the answer we will divide 72$ by 18 and we get 4$.
The number of sandwiches and the total price of sandwiches are directly proportional.
Cost of 18 sandwiches = $72
Cost of 1 sandwich = $72/18
= $4
Hence the cost of 1 sandwich is $4.

1. Michael and 6 friends went to the movies. There, they each bought movie tickets and a bag of popcorn to share among them all. Michael used the expression 7t + 4.50 to find the total cost. a) What is the variable and what does it represent in the expression? Explain.
Answers
Answer:
The variable is t
t represent the cost of movie tickets
Step-by-step explanation:
Given:
Total cost = 7t + 4.50
The variable is t
Michael + 6 friends = 7 people
4.50 represent the cost of popcorn
t represent the cost of movie tickets
For instance,
If the cost of a movie tickets is $2
Then,
t = 2
Total cost = 7t + 4.50
= 7(2) + 4.50
= 14 + 4.50
= 18.50
Total cost = $18.50

Given f(x)=3(x-1)(x-7) what is the minimum output value of the function
Answers
Answer:
-27
Step-by-step explanation:
f(x) = 3(x-1)(x-7)
= (3x-3)(x-7)
= 3x^2 - 24x + 21
when f(x) = 0, x = 7 or 1
x-intercept of vertix of the graph = (7+1 )/ 2 = 4
f(x) attains it's minimum when x = 4
The minimum output value = 3(4-1)(4-7) = -27
There is a line that includes the point (3, 3) and has a slope of 4. What is its equation in
slope-intercept form?
Answers
Answer:
y = 4x - 9Step-by-step explanation:
The equation in point-slope form with slpope of m and including point (x₁,y₁) is:
y - y₁ = m(x - x₁)
m = 4
(3, 3) ⇒ x₁ = 3, y₁ = 3
So:
y - 3 = 4(x - 3) ← the point-slope form
y - 3 = 4x - 12 {add 3 to both sides}
y = 4x - 9 ← the slope-intercept form
