Answer:
Volume of cone = 418.67 cm³ (Approx.)
Step-by-step explanation:
Given:
Radius of cone = 5 cm
Height of cone = 16 cm
Find:
Volume of cone
Computation:
Volume of cone = [1/3][π][r²][h]
Volume of cone = [1/3][3.14][5²][16]
Volume of cone = [1/3][3.14][25][16]
Volume of cone = [1/3][3.14][400]
Volume of cone = [1/3][1,256]
Volume of cone = 418.67 cm³ (Approx.)

Answer:
The two sets would be 21,22,23 and -21, -22, and -23
Step-by-step explanation:
This is because a negative number squared would be positive.
So -21^2+-22^2+-23^2 would equal the same as 21^2+22^2+23^2 which would be 1454.

Tangent:A tangent to a circle is a straight line which touches the circle at only one point.
The tangent TU and UV intersect at point U.
Therefore,
m∠x = 1 / 2 (arc VST - 108)
arc VST = 360 - 108 = 252
m∠x = 252 - 108 / 2
m∠x = 144 / 2

Answer:
Step-by-step explanation:
510/85 = 6
Sandwich type quantity
penutbutter 37 X 6 = 222
Ham 18 X 6 = 108
egg salad 5 X 6 = 30

A Mustang GT on Missouri has a marked price of $60,000. If paid in cash you are to pay 15% less than the marked price. It also have a hire purchase plan which states to pay 30% of the marked price and $1000 monthly payments for 4 yrs.
A) Discount on Cash price.
B) Cash Price.
C) Amount Payable.
D ) Hire Purchase Price
E ) Difference between the Hire Purchase price and the Cash Price.
Answer:
A) Discount on Cash price. ($9,000 )
B) Cash Price. ($51,000 )
C) Amount Payable. ($51,000 )
D ) Hire Purchase Price ($66,000 )
E ) Difference between the Hire Purchase price and the Cash Price. ($15,000 )
Step-by-step explanation:
The following is the workings:
The GT Missouri marked price = $60,000
If paying cash,
Discount = 15%
(15/ 100 ) x $60,000 = $9,000
Actual Price (less discount) = $60,000 - $9000 = $51,000
If hire purchase,
Firstly, 30% marked price,
= (30/100) x $60,000 = $18,000
Monthly payment = $1000
Period = 4 years = 4 x 12 = 48 months
Total monthly payment,
$1000 x 48 = $48, 000
Therefore, total hire purchase payment
Monthly payment + initial 30% payment
= $18,000 + $48,000 = $66,000
Difference between hire purchase and cash price,
= $66,000 - $51,000 = $15,000
A triangle has side lengths of 25in, 30in, and 50 in. Classify it as acute, obtuse, or right. Please help me.
9514 1404 393
Answer:
obtuse
Step-by-step explanation:
Using the idea of a "form factor", we find ...
f = a² + b² - c²
f = 25² +30² -50² = 625 +900 -2500 = -975
The form factor is negative, so the triangle is obtuse.
_____
Additional comment
The form factor, as defined above, classifies the triangle according to its sign:
f > 0 . . . acute
f = 0 . . . right
f < 0 . . . obtuse
The largest angle in the triangle can be found from ...
cos(C) = f/(2ab)
Here, it is C = arccos(-975/1500) ≈ 130.5416°

Preliminary data analyses indicate that you can consider the assumptions for using nonpooled t-procedures satisfied. Researchers obtained data on the number of acute postoperative days in the hospital using the dynamic and static systems. At the 10% significance level, do the data provide sufficient evidence to conclude that the mean number of acute postoperative days in the hospital is smaller with the dynamic system than with the static system?
Answer: hello some data is missing from your question attached below is the missing data
answer :
At 10% significance level ; critical value with the dynamic system = -1.3637
critical value with the static system = - 1.4759
hence the data provided is sufficient evidence that mean number of acute postoperative days in the hospital is smaller with the dynamic system
Step-by-step explanation:
At 10% significance level ; critical value with the dynamic system = -1.3637
critical value with the static system = - 1.4759
hence the data provided is sufficient evidence
Given ∝ = 0.10
i) mean number of dynamic system = ( x1 ) = 7.08
s1 ( std of sample ) = 1.51
sample size = 12
df ( degree of freedom ) = n - 1 = 11
Hence critical value : t∝,11 = -1.3637 ( = T.INV(0.1,11)
ii) mean number of static system
( x2 ) = 11.33
s2 ( std of static sample ) = 3.83
sample size = 6
df( degree of freedom ) = n -1 = 5
critical value = t∝,5 = -1.4759 ( = T.INV(0.1,5) )

When Maria finished medical school, she owed $36,000 in student loans. She repaid of the total
1/3 amount within two years of graduating. How much did Maria owe two years after graduating?
Answer:
$24,000

To find how much she owed, find 2/3 of 36,000, since she repaid 1/3
36000(2/3)
= 24,000
So, two years after graduating, Maria owed $24,000

Answer:
An easy way to tell with a number like this is that both numbers are round, so they can both be divided by 2
Step-by-step explanation:
You can tell that it is not simplified if they are both even, as they can be divided by 2, or really, if both numbers have a common factor as a divisor.
For example, 3/6 has a common of factor by 3, 3/3 / 3/6 = 1/2.

The legs of a right triangle each measure 44 inches. Find the length of the hypotenuse.
Answer:
Length of hypotenuse = 44√2 in²
Step-by-step explanation:
Given:
Length of legs = 44 in
So,
Perpendicular = 44 in
Base = 44 in
Find:
Length of hypotenuse
Computation:
Hypotenuse = √Perpendicular² + Base²
Length of hypotenuse = √44² + 44²
Length of hypotenuse = 44√2 in²

Answer:
B. the mean is 59 inches
Step-by-step explanation:
if you add the number of inches together you get 413. 413 divided by 7 is 59. that is the mean.
Answer:
B: The mean wingspan is 59 inches.
Step-by-step explanation:
The mean is the average so when you add up all of the wingspans 53+59+59+60+60+61+61 you get 413, and to find the mean you would divide that by seven (413/7), because there are 7 students, which is 59.
