A school’s auditorium can hold a maximum of 450 people. The school is holding a talent show
where 35 students will perform. The school pre-sold 345 tickets to the show and will now allow
the performers to use the remaining tickets for their friends and family. If each student
performing in the talent show can invite the same number of guests, select all of the following
that represents the possible number of guests that arrive for each performer.
Answer:
Each can invite 2 guest
Step-by-step explanation:
345+ 35= 380
450-380 = 70
70/35=2
Answer:
Each performer can get 2 guests.
Step-by-step explanation:
There are 35 performers and 345 pre-sold tickets, so we just need to subract them from the amount of people that the stadium can hold. 450 - 35 - 345 = 70 people left
Since there is space for 70 more people, each performer can get (70/35) = 2 guests

How much change should sara receive from the $10 bill?
Answer:
$3.56
Step-by-step explanation:
mark me brainlest please
Answer:
3.56
Step-by-step explanation:
First you wanna add the prices of all the food so its
Two Eggs= 3.38
Slice of Bacon= 1.49
Orange Juice= 1.09
Add All then you get 5.96 and add sales tax so you get 6.44
The Subtract 10.00 - 6.44 = A/3.56

Answer: So, you got the length of side C. You now need to find what 10 is squared, then what plus what (in squared gates you there). A squared plus B squared is C squared. It is basic Pythagorean Threom.
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
For this I think you should know what SOH-CAH-TOA is, if not here.
O=opposite, A=adjacent(side), and H=-hypotenuse. We see they give us the right angle we need to solve, remember that we need the angle to the side of the right angle. Now S=sin, C=cos, T=tan, with these we use them to solve in the calculator. If you don't have a calculator, its going to be hard. But if you have a Ti-84 then set it to Degree mode. Ok moving on, We see they give us the adjacent and the hypotenuse, not the opposite.(from the given angle) So we can take off, SOH and TOA, see it doesn't have or has the incorrect sides. So we have left CAH.
Equation time:
, we see that the x is on top so we just multiply....

Find the value of x and y that will make each quadrilateral a parallelogram.
Answer:
6
Step-by-step explanation:
Answer:
x = 15, y = 7
Step-by-step explanation:
opposite angles are congruent in a parallelogram:
=> 3x + 4 = 7y
=> 3x - 7y = -4
the same-side interior angles of a parallelogram are supplementary angles, which means they sum to 180°:
=> 8x + 11 + 7y = 180
=> 8x + 7y = 169
add the two equation 3x - 7y = -4 and 8x + 7y = 169 to eliminate y and solve for x:
=> 3x - 7y = -4
8x + 7y = 169
+) ___________
11x = 165 => x = 15
plug x = 15 into one of the two equation to solve for y:
=> 3(15) - 7y = -4
=> 45 - 7y = -4
=> 7y = 49
=> y = 7

Factor completely. 5x^2-20x+20=5x 2 −20x+20
Step-by-step explanation:
5x^2 - 20x + 20 = 5x^2 - 20x + 20
5(x^2 - 4x + 4) = 5(x^2 - 4x + 4)
(5 + 5) (x^2 - 4x + 4)
the sun shines on a flagpole, causing a shadow to be cast on the ground. the distance from the base of the pole to the tip of the shadow is 49 feet. at that time of day, the sun's rays make an angle of 38° with the ground. How tall is the flagpole?
Answer:
30.17feet high
Step-by-step explanation:
Given the following
the distance from the base of the pole to the tip of the shadow = 49feet (hypotenuse)
angle of elevation = 38°
Required
Height of the flagpole (opposite)
Using the SOH CAH TOA identity
Sin theta = opposite/hypotenuse
Sin 38 = H/49
H = 49sin38
H = 49(0.6157)
H = 30.17feet
Hence the flagpole is 30.17feet high

The formula for the circumference of a circle is [tex]\pi d[/tex].
In a:
The radius is 8 cm.
Therefore the diameter (d) would be 16cm (8 * 2)
Hence, the circumference is [tex]16\pi[/tex]
In b:
The diameter is already given: 13 in.
Thus, the circumference is [tex]13\pi =40.84[/tex] (2dp)
The perimeter of a rectangle is 13 cm and its width is 2 ¾ cm. Find its length in cm.
Answer:
length = 3 3/4
Step-by-step explanation:
13 = 2(2 3/4) + 2l
13 = 2(11/4) + 2l
13 = 22/4 + 2l
52/4 - 22/4 = 2l
30/4 = 2l
30/4 ÷ 2 = l
30/4 x 1/2 = l
30/8 = l
length = 15/4 or 3 3/4

The entrance hall in Black's family house has a perimeter of 71 2/3 ft.IF it is 9 2/5 ft wide, how long is it?
Answer: 26 13/30 feet
Step-by-step explanation:
The hall is in the shape of a rectangle. The perimeter of a rectangle is:
= 2(length + width)
= 2l + 2w
Since perimeter = 71 2/3 ft and Width = 9 2/5 ft wide, the length will be calculated thus:
Perimeter = 2l + 2w
71⅔ = 2l + 2(9 2/5)
71 2/3 = 2l + (2 × 47/5)
71 2/3 = 2l + 94/5
71 2/3 = 2l + 18 4/5
Collect like terms
2l = 71 2/3 - 18 4/5
2l = 71 10/15 - 18 12/15
2l = 52 13/15
l = (52 13/15 ÷ 2)
l = 793/15 × 1/2
l = 793/30
l = 26 13/30
Therefore, the length is 26 13/30ft

What is a z-core?A z-core is also known as a standard score and it can be defined as a measure of the distance between a data point (raw score) and the mean, when standard deviation units are used.
In Statistics, z-scores can either be positive or negative and it is calculated by using this formula:
[tex]Z=\frac{x\;-\;u}{\delta}[/tex]
Where:
x is the sample mean or observed data.u is the mean.[tex]\delta[/tex] is the standard deviation.In this exercise, we would have the smallest probability for P(z > 2), when z is a standard Normal random variable.

1. Find x.
Answer:
x= 25.5 not rounded x=25.51393657
Step-by-step explanation:
Decide what trig ration you need/want to use. The 27 degrees are opposite of the 13 and adjacent to the x which means your ratio should be o/a or 13/x. The trig ratio needed is Tangent. Now you can write the equation as tan(27)=13/x and start solving.
tan(27)=13/x multiply the x on both sides and you'll have x * tan(27)=13 and decide which to put into your calculator and you'll get x=25.51393657 rounded as 25.5
