Answer:
A. 47%
Step-by-step explanation:
The total amount of people who preferred indoor seating was 70. The total amount of people sureveyed was 148. So 70 divided by 148, or 70/148, is
0.47 =47%

Step-by-step explanation:
∠a and ∠b are complementary angles. ∠a measures 22°.
what is the measure of ∠b?
Answer:
∠b = 68°
Step-by-step explanation:
Complementary angles are a pair of angles that, added together, equal 90°.
If ∠a = 22°, then the measure of∠b must equal 90° when added to that of ∠a.
To find the measure of ∠b, then, we can subtract ∠a from 90°.
90 - 22 = 68
The measure of ∠b, then, is 68°.
I hope this is helpful ^^
Good luck

Step-by-step explanation:
A rectangular carport has area of one 50 ft.The width of the carport is 5 feet less than twice its length. Find the length and width of the carport
Width= ? feet,
Length= ? feet
Answer:
[tex]Length = 10ft[/tex]
[tex]Width = 15ft[/tex]
Step-by-step explanation:
Given
[tex]W= Width\\ L = Length[/tex]
[tex]Area = 150[/tex]
[tex]W=2*L- 5[/tex]
Required
Determine the dimension
Area is calculated as:
[tex]Area = L * W[/tex]
So, we have:
[tex]L * W = 150[/tex]
Substitute: [tex]W=2*L- 5[/tex]
[tex]L * (2*L-5) = 150[/tex]
[tex]L * (2L-5) = 150[/tex]
Open bracket
[tex]2L^2 - 5L = 150[/tex]
Rewrite as:
[tex]2L^2 - 5L - 150=0[/tex]
Expand
[tex]2L^2 -20L + 15L - 150 = 0[/tex]
Factorize:
[tex]2L(L -10) + 15(L - 10) = 0[/tex]
[tex](2L + 15) (L - 10) = 0[/tex]
Split
[tex]2L + 15=0[/tex] or [tex]L -10 = 0[/tex]
Solve for L
[tex]2L =-15[/tex] or [tex]L = 10[/tex]
L cannot be negative
So:
[tex]L = 10[/tex]
Substitute [tex]L = 10[/tex] in [tex]W=2*L- 5[/tex]
[tex]W = 2 * 10 - 5[/tex]
[tex]W = 20 - 5[/tex]
[tex]W = 15[/tex]
Hence:
[tex]Length = 10ft[/tex]
[tex]Width = 15ft[/tex]

Find the area base = x+8 height x+7
9514 1404 393
Answer:
x² +15x +56
Step-by-step explanation:
We presume these are dimensions of a rectangle, so the area is their product.
A = (x +8)(x +7) = x(x +7) +8(x +7) = x² +7x +8x +56
A = x² +15x +56

In Devon's school, the morning session runs for a total of 182 minutes. The morning session
includes 4 class periods of equal length and a homeroom period that lasts for 10 minutes.
Using the variable m to represent minutes, write an equation that can be used to find the
length of each class period. Then solve for m.
Answer:
Every class period is 43 minutes long.
Equation:
(m - 10) ÷ 4
A new car is purchased for $26,000 and over time its value depreciates by one half
every 5 years. What is the value of the car 7 years after it was purchased, to the
nearest hundred dollars?
Answer: $203
Step-by-step explanation: We first start out with the exponential decay model which is y=a(1-r)^t, then plug in the numbers of your problem:
-y=26,000(1-0.50)^7
-y=26,000*0.50^7
-y=26,000*0.0078125
-y=203.125
Then, after rounding to the nearest hundred dollars you get your answer....
:) hope this helped a bit
The value of the car 7 years after it was purchased will be $203.
What is exponential decay?A quantity lowers gradually at first during exponential decay before rapidly declining after that. Half-life may be calculated using the exponential decay formula, which is also used to estimate population decrease.
It is given that, A brand-new car costs $26,000 to buy, and every five years, its value decreases by 50%.
We have to find the value of the car 7 years after it was purchased
The exponential decay model, y=a(1-r)t, is where we begin. The data from your problem are then entered.
y=-26,000(1-0.50)^7
y=-26,000*0.50^7
y=-26,000*0.0078125
y=-203.125 (-ve shows the value is declining)
Thus, the car will be worth $203 seven years after it was bought.

According to Wine-Searcher, wine critics generally use a wine-scoring scale to communicate their opinions on the relative quality of wines. Wine scores range from to , with a score of indicating a great wine, indicating an outstanding wine, indicating a very good wine, indicating a good wine, indicating a mediocre wine, and below indicating that the wine is not recommended. Random ratings of a pinot noir recently produced by a newly established vineyard in follow: Excel File: data07-11.xlsx 87 91 86 82 72 91 60 77 80 79 83 96 a. Develop a point estimate of mean wine score for this pinot noir (to decimals).

Answer:
62 + 64 + 55 + s = 242
61 students will ride Bus #4.
Step-by-step explanation:
The equation I will use here is 62 + 64 + 55 + s = 242
62 + 64 + 55 + s = 242 {Going from left to right, subtract 62, 64, & 55 from 242}
64 + 55 + s = 180 {242 - 62 = 180}
55 + s = 116 {180 - 64 = 116}
s = 61 {116 - 55 = 61}
61 students will ride Bus #4.

Answer:
c = 2.9 yards
Step-by-step explanation:
2c = 42.4 - (18.3 x 2)
2c = 42.4 - 36.6
2c = 5.8
c = 5.8 / 2
c = 2.9 yards

Solve by completing the square:
x^2 + 3x - 9 = 0
Answer:
Step-by-step explanation:
x^2 + 3x - 9 =0
By comparing with the equation ax^2+bx+c = 0,
we get,
a = 1, b=3, c = -9
we know the formula for x is,
x = (-b±√(b^2 - 4ac))/2a
x = (-3±√45)/2
x = (-3±3√5)/2
x = (-3+3√5)/2, (-3-3√5)/2
Answer:
2 solutions. x = -3/2 + 3/2 * sqrt(5) and x = -3/2 + -3/2 * sqrt(5)
Step-by-step explanation:
Let's solve your equation step by step.x^2 + 3x −9 = 0
For this equation: a=1, b=3, c=-9
1x^2 + 3x+ −9 = 0
Step 1: Use quadratic formula with a=1, b=3, c=-9.
x = (-b ± [tex]\sqrt{b^2 - 4ac}[/tex])/2a
x = (-3 ± [tex]\sqrt{3^2 - 4(1)(-9)}[/tex])/2a
x = (-3 ± [tex]\sqrt{45}[/tex])/2
x = -3/2 + 3/2 * sqrt(5) or x = -3/2 + -3/2 * sqrt(5)

What is the approximate length?
9514 1404 393
Answer:
(a) 75.5
Step-by-step explanation:
There are two ways you can work this.
Pythagorean theorem
Triangle CMP is a right triangle. CM = AC = 55. CP = CB -PB = 55 -15 = 40. Then length PM can be found from ...
PM² +CP² = CM²
PM = √(CM² -CP²) = √(55² -40²) = √1425 ≈ 37.749
The length MN is twice the length of PM, so is ...
MN = 2×PM = 2×37.349 = 75.498
The length of MN is about 75.5.
__
Using chord relationships
The products of the different lengths for the same chord are the same for the crossed chords.
AP×PB = MP×PN
We know MP = PN, so ...
MP = √(AP×PB) = √((55+40)(15)) = √1425
As before, MN = 2×MP = 2√1425
MN ≈ 75.5
One of Natalia's professors claims that 13% of the students at their college frequently wear hats. Natalia feels that the actual rate is much lower. She selects a random sample of 100 students at the college and finds that only 9 of them wear hats frequently. To determine if her data provide convincing evidence that the true proportion is less than 13%, she conducts 200 trials of a simulation. Natalia is testing the hypotheses. H o p = 13% and Ha p< 13%, where p = the true proportion of students at the college who frequently wear hats. Based on the results of the simulation, what is an estimate of the P-value of the test?
