Answer:
5²+1×2 - 4(4) = 11
Step-by-step explanation:
up top when it says a = 4
and b = 5 that's means b and a are those numbers.
then while 4 is touching a that means to multiply. And the 2 up top of b means 5×5, then do order of operations to find the answer. If you dont you'll get it WRONG.
Order of operations is this
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
If you partition ¼ into 6 equal segments, how long is each segment?
Answer:
1/24
Step-by-step explanation
I'm pretty sure that you just do 1/4 times 6 to get 1/24 so each segment will be 1/24.
A parking lot costs $1300 a month to operate, and it spends $260 each
month for every car that parks there. The parking lot charges a monthly fee of
$450 to park a car. If n is the number of cars, which equation represents the
profit function of the parking lot?
A. p= 710n+ 1300
B. p = 710n- 1300
c. p= 190n - 1300
D. p= 190n + 1300
SUBMIT
A
Answer:
[tex]p = 190n - 1300[/tex]
Step-by-step explanation:
Given
[tex]Monthly = 1300[/tex]
[tex]Expenses = 260[/tex] per car
[tex]Charges = 450[/tex] per car
Required
Determine the profit
Let the number of cars be n. So:
Express on n cars is: 260n
Charges on n cars is 450n
The profit (p) is then represented as:
[tex]p = Charges - Expenses - Monthly\ Expenses[/tex]
[tex]p = 450n - 260n - 1300[/tex]
[tex]p = 190n - 1300[/tex]

Help plz....................
Answer:
x = 136°
y = 44°
Step-by-step explanation:
x + 44° = 180° (Adjacent angles of a parallelogram)
x = 180° - 44°
x = 136°
y = 44° (Opposite angles of a parallelogram)

Answer:
1. 9 bounds of carbon dioxide
2. 27 bounds of carbon dioxide
Step-by-step explanation:
So let's find a unit rate: 1 to 9
"Why is it 1:9?"
If I can find divide 72 pounds into 8 hours? What would I find? You would find the pounds for each other
Example: 72/8=9. So If 9 carbon dioxide per hour. I can do 3 hours is 27 pounds of carbon dioxide.
So to sum it up, 72/8=9 so 1:9 can be used to figure out any amount of pounds used in a certain number of hours. So If 3 hours, then 27 pounds.
Answer:
1. 9 pounds of carbon dioxide
2. 27 pounds of carbon dioxide
Step-by-step explanation:
Well, I just know it.

Answer:
x ≈ 18.3°
Step-by-step explanation:
Reference angle = x
Opposite side = 11
Hypotenuse = 35
Apply SOH:
Sin x = opp/hyp
Sin x = 11/35
[tex] x = sin^{-1}(\frac{11}{35}) [/tex]
x ≈ 18.3°

8y + -5(-y + 2)
Pls help simplify the expression !!
Answer:
13y-10
Step-by-step explanation:
Expand: -5(-y+2): 5y-10
Add similiar elements: 8y+5y=13y
=13y-10
Answer:
-5 x -y = 5y
-5 x 2 = -10
8y + 5y = 13y
therefore your expression is:
13y - 10
A news report states that the 99% confidence interval for the mean number of daily calories consumed by participants in a medical study is (1850, 2000). Assume the population distribution for daily calories consumed is normally distributed and that the confidence interval was based on a simple random sample of 18 observations. Calculate the sample mean, the margin of error, and the sample standard deviation based on the stated confidence interval and the given sample size. Use the t distribution in any calculations and round non-integer results to 4 decimal places.
Answer:
The sample mean is of 1925 calories.
The margin of error is of 75 calories.
The sample standard deviation is of 109.7992 calories.
Step-by-step explanation:
Sample mean:
The sample mean is the mean value of the two bounds of the confidence interval. So
[tex]M = \frac{1850 + 2000}{2} = 1925[/tex]
The sample mean is of 1925 calories.
The margin of error
Difference between the bounds and the sample mean. So
2000 - 1925 = 1925 - 1850 = 75 calories.
The margin of error is of 75 calories.
Sample standard deviation:
Here, I am going to expand on the t-distribution.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 18 - 1 = 17
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 17 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 2.898
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}}[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
Since [tex]M = 75, T = 2.898, n = 18[/tex]
[tex]M = T\frac{s}{\sqrt{n}}[/tex]
[tex]75 = 2.898\frac{s}{\sqrt{18}}[/tex]
[tex]s = \frac{75\sqrt{18}}{2.898}[/tex]
[tex]s = 109.7992[/tex]
The sample standard deviation is of 109.7992 calories.

Answer:
$6.75
Step-by-step explanation:
To solve any percent problem, u can use the equation part %
------- = ---
whole 100
(the lines are fraction bars btw, when u right out the problem, write it as fractions)
In this problem, the whole is 45, because that is the original, or whole price. The % is 15, because u want to find 15%. The part would be x, because that's what u want to find. Cross multiply, so ur problem should look like this:
100x = 675.
Then, divide 675 by 100 to get x = 6.75.
So Natalie saves $6.75.
hope this helps!

width - 36 cm
length - 32 cm
What would be the dimensions of the poster at 4 times its current size? (5 points)
O Length - 128 cm, width = 144 cm
O Length - 28 cm, width - 32 cm
O Length = 36 cm, width =
O cm
O Length = 8 cm, width = 9 cm
Answer:
Length=8 cm ,width=9 cm .
Step-by-step explanation:
Given in rectangle
Length of the rectangle=32 cm
Width of the rectangle= 36 cm
According to question
Length of poster= times length of rectangle
Length of poster=
Length of poster=8 cm.
By simplification
Width of poster= times width of rectangle
Width of poster=
Width of poster= 9 cm
By simplification
Hence, Length of poster=8 cm and width of poster=9 cm.
