Answer:
372215
Step-by-step explanation:
Total people in concert = Total seats for attendants + additional employees
Seats for public attendants = Rows x seats per rows = 610 x 610 = 372100
Additional employees = 20% of 575 = ( 20/100 ) x 575 = 115
So, total people in concert = 372100 + 115 = 372215

Use equivalent ratios to find the unknown value.
Answer:
66 is equal to K
Step-by-step explanation:
if 4 times 6 equal 24
then 11 time 6 equals 66
in this case, the scale factor is 6.
Have a wonderful day!
Answer:
K = 66
Step-by-step explanation:
[tex]\frac{k}{24} = \frac{11}{4}[/tex]
when taking a look at this, first try to see if you can solve the denominator.
24 to 4 equals 6 meaning you divide k by 6 will be equal to 11
Then 11 x 6 = 66!!

Convert (4, 3π/2) to rectangular form.
A) (0,4)
B) (0, -4)
C) (-4,0)
D) (4,0)
Answer:
(0, -4)
Step-by-step explanation:
The rectangular form is expressed as;
x = rcos theta
y = rsin theta
Given the coordinate (4, 3π/2)
r = 4
theta = 3π/2
Substitute
x = 4cos3π/2
x = 4cos270
x = 4(0)
x = 0
y= 4sin3π/2
y = 4sin270
y = 4(-1)
y = -4
Hence the required coordinate is (0, -4)

Step-by-step explanation:
The total of the interior angles of a triange is 180 degrees
You can see that we are already given 2 sides: 41 degrees and 90 degrees (the right angle)
To find the remaining angle, we solve=180=41+90+x
x=49 degrees

Andre can run 2 1/2 miles in 3/4 hour. Find his average speed in miles per hour.
Answer:
3 1/3 miles per hour
Step-by-step explanation:
(5/2 ÷ 3/4) = (s ÷1)
(5/2 ÷ 3/4) = 10/3
10/3 = s/1
cross-multiply:
3s = 10
s = 10/3
s = 3 1/3 miles per hour
Answer:
3 1/3 mph

Which expression could be used to determine the perimeter of the triangle?
A 9x + 4
B 9(x + 4)
C 13x
D 13(x + 1)
Answer:
A. 9x + 4
Step-by-step explanation:
Perimeter of a triangle = side A + side B + side C
Side A = 2.5x + 3
Side B = x + 6
Side C = 5.5x - 5
Perimeter of a triangle = side A + side B + side C
= (2.5x + 3) + (x + 6) + (5.5x - 5)
= 2.5x + 3 + x + 6 + 5.5x - 5
= 2.5x + x + 5.5x + 3 + 6 - 5
= 9x + 4
Perimeter of a triangle = 9x + 4
The correct answer is A. 9x + 4

A can of nuts weighs 1 pound, 1 ounce. The empty can weighs 3 ounces. If you pour out half the nuts into a bowl, how many ounces of nuts are in the bowl?
Answer:
7 ounces
Step-by-step explanation:
There are 16 ounces in one pound, so there are 17 ounces for the can of nuts.
Since the empty can weighs 3 ounces, you can subtract 17-3, which equals 14, to get the weight of the nuts alone.
Then, you divide 14 by 2, and you get 7.
The sum of David and Jacobs age is 39. Two years ago David was four times Jacobs age. How old are three now?
Answer:
David is 30
Jacob is 9
Step-by-step explanation:
The sum of David and Jacobs age is 39
d + j = 39
d = 39 - j
----------------------
Two years ago David was four times Jacobs age
(d - 2) = 4(j - 2)
d - 2 = 4j - 8
d = 4j - 6
---------------------
Set the equations equal
4j - 6 = 39 - j
5j = 45
j = 9
d = 4(9) - 6
d = 30

Hi there!
you can use the Pythageron Therom for this one.
Basically you just need to apply this formula: a^2 + b^2 = c^2
And then find the root of the hypotenuse.
So, 15^2 + 8^2 = the hypotenuse^2
Which equals, 225 + 64 = 289
Square root of 289 = 17
17 is the answer you are looking for!

Answer:
900 ft cubed
Step-by-step explanation:
v=pi*r sqaured* h
The radius is 5 and sqaure 5 to get to 25. Multiply that by pi, which in your case is 3, and you get 25. Then mulitply that by 12, height, and you get your answer is 900.
Lmk if you need more help
Also, to do this on the calulator is easy as well. Just times pi(3 for you) by the raduis twice and then times that by the height. For example, for this question, I just typed in my calculator, 3 times 5 times 5 times 12 and I got 900.
Sorry if this doesn't make sense lol I'm not good at explaining things.
A rectangle is placed around a semicircle as shown below. The length of the rectangle is 8 cm. Find the area of the shaded region. Use the value 3.14 for at, and do not round your answer. Be sure to include the correct unit in your answer.
PLEASE HELP
Answer:
Area of the shaded region = 6.88 cm²
Step-by-step explanation:
Area of the shaded region = Area of the rectangle - Area of the semicircle
Area of the rectangle = Length × Width
Length of the rectangle = AD = 8 cm
Width of the rectangle = OP = 4 cm [OP, OB and OC are the radii of the circle which are equal in measures]
Area of the rectangle = 8 × 4 = 32 cm²
Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
= [tex]\frac{1}{2}\pi (OP)^{2}[/tex]
= [tex]\frac{1}{2}\pi (4)^{2}[/tex]
= 25.12 cm²
Area of the shaded region = 32 - 25.12
= 6.88 cm²
The perimeter of the polygon is_______units.
Answer:
3 units
Step-by-step explanation:
Since the sides are congruent, then
5 - 2x = - 4x + 9 ( add 4x to both sides )
5 + 2x = 9 ( subtract 5 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
Then
5 - 2x = 5 - 2(2) = 5 - 4 = 1
perimeter = 3 × 1 = 3 units

Answer:
C) Each ounce of yogurt increases the cost by $0.37
Step-by-step explanation:
With 0 ounces of yogurt, you have a flat fee of $1.50 for toppings
With 1 ounce of yogurt, you have a total of $0.37(1) + $1.50 = $1.87
With 2 ounces of yogurt, you have a total of $0.37(2) + $1.50 = $2.24
And so on...
Notice that with each ounce of yogurt, the price is increased at a rate of $0.37 per ounce. $1.50 is what you're just starting with, without yogurt. Therefore, option C is correct.
