Answer:
53.12ft
Step-by-step explanation:
Area of triangle:
The formula to find the area of a triangle is 1/2bh
- We plug in the values given.
1/2 x 8 x 7
Which is 28ft.
Area of semicircle:
The formula to find the area of a semicircle is 1/2[tex]\pi[/tex][tex]r^{2}[/tex]
- We plug in the values given
1/2 x [tex]\pi[/tex] x [tex]4^{2}[/tex]
1/2 x 16[tex]\pi[/tex]
8[tex]\pi[/tex] or 8 x 3.14 = 25.12
In order to get the total area of the whole shape we need to add the areas of those two, which will be 25.12 + 28 = 53.12

Step-by-step explanation:
the amount of time they have is not changed, however the amount of bands they can fit into that time slot is undetermined and relies on the time they have
Answer:
the first option
Step-by-step explanation:
independent is something you can change OR determine
dependent is something that will happen BECAUSE of the independent and you can not change it
in this case- the sentence states that " the amount of time that the venue has been reserved for DETERMINES how many bands will play"
You can change or schedule how long you want to reserve the venue but how many bands that will play depends on the independent variable (t)
Thats why it say determines, because (t) determines or changes (b)

The mean of four numbers is 7. Three of the numbers are 5, 7, and 7. What is the fourth number? Show your work.
Answer:
4th number = 9Step-by-step explanation:
let 4th number = X
mean = 7
observations = 5, 7, 7, X
..............................................
mean = sum of observations ÷ numbers of observations
7 = 5+7+7+X ÷ 4
28 = 19 + X
28 - 19 = X
9 = X
The mean of the four numbers is 7. Three of the numbers are 5, 7, and 7. So, the 4th number would be 9.
How to find the mean value of a data set?The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.
If the data set consists of values
[tex]x_1, x_2, ..., x_n[/tex]
, then we get the mean value as:
[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]
The mean of the four numbers is 7. Three of the numbers are 5, 7, and 7.
let 4th number = X
Mean = 7
observations = 5, 7, 7, X
Mean = sum of observations / numbers of observations
[tex]7 = 5+7+7+X / 4\\28 = 19 + X\\28 - 19 = X\\9 = X[/tex]

A juice factory offers its juice in both bottles and cans. A class of students on a field trip decides to compare the numbers of cases of bottled juice and canned juice that are packaged each minute. The students count the number of cases that are packaged on each assembly line over several minutes.
What is the unit rate for canned juice, in cases per minute? Explain how you found this unit rate.
Answer: 50 cases per minute
Step-by-step explanation:
1. Select one of the points on the graph. Let's use (2, 100) in this case.
2. Divide the number of cases (y) by the amount of minutes (x) This means the equation would be 100 ÷ 2.
3. Since 100 cases ÷ 2 minutes = 50 cases per minute, that means that is unit rate, which can be expressed by y = 50x or f(x) = 50x.

Julius needs to determine how much information needs to be given about an isosceles triangle to be able to draw an isosceles triangle. He is looking at six different cases and is trying to determine if that amount of detail will allow him to construct just one isosceles triangle or if it allows for more than one isosceles triangle.
Case 1. The length of the two congruent sides and the measure of the included angle.
Case 2. The lengths of two non-congruent sides and the measure of the included angle.
Case 3. The lengths of two non-congruent sides.
Case 4. The measure of the two congruent angles and the included side.

Help asap pls. The mean of a math test took by 50 students is 85% Two students got a 10% on the test. If those outliers were removed, what would the new mean be? Pls don't answer for points. And also DONT ANSWER TO ASK A QUESTION COMMENT IT. it takes away a chance for people who actually know the answer to answer
Answer:
okay I'm not 100% sure but I have a good idea (it's okay if u remove me it's just an educated guess)
89%
Step-by-step explanation:
if there were 100 students that would mean 1 student represented 1% of the results. so if there were 50 students 1 student would represent 2% of the results. so if two students were removed then that would mean the result would improve by a total of 4% which would get you 89%
