Answer:
D. 27 units
Step-by-step explanation:
27 is greater than 20. The scale factor is more than 1, so the answer(s) have to be more than 1.
NO LINKS!! Use the cylinder shown to mark each statement as true or false. Rewrite and correct any false statements.
Problem 9
Answer: FalseReason:
The height of the cylinder is 2.5 ft. It's misleading because the cylinder is tipped onto its side, so it appears that 4 ft is the height. The height of any cylinder is always perpendicular to the circular base. It might help to rotate the paper so that the circular base is horizontal.
==============================================================
Problem 10
Answer: FalseReason:
The diameter of the base is 4 feet, which divides in half to 2 feet and it's the radius of the circle.
Area = pi*(radius)^2 = pi(2)^2 = 4pi
So the area expression should be either pi(2^2) or pi(4) or 4pi
==============================================================
Problem 11
Answer: TrueReason:
V = pi*r^2*h
V = 3.14*2^2*2.5
V = 31.4 cubic feet
This volume is approximate since pi = 3.14 is approximate.
Rajani has a bag that contains strawberry chews, cherry chews, and lime chews. She performs an experiment. Rajani randomly removes a chew from the bag, records the result, and returns the chew to the bag. Rajani performs the experiment 38 times. The results are shown below: A strawberry chew was selected 23 times. A cherry chew was selected 4 times. A lime chew was selected 11 times. Based on these results, express the probability that the next chew Rajani removes from the bag will be strawberry or cherry as a fraction in simplest form.

A trapezoid has sides of length 11 inches, 1.5 inches, 11 inches, and 19.1 inches. What is the perimeter?
Answer:
The Perimeter of the trapezoid = 42.6 inches
Step-by-step explanation:
______
Formula:
let a , b , c , d be consecutively the lengths of the sides of the trapezoid
then
The Perimeter of the trapezoid = a + b + c + d
___________________________________
Suppose a = 11 , b = 1.5 , c = 11 , d = 19.1
therefore,
The Perimeter of the trapezoid = a + b + c + d
= 11 + 1.5 + 11 + 19.1
= 42.6

Step-by-step explanation:

⇢ - 3x + 5x = 4 - 5
⇢ 2x = -1
⇢ 2x/2.= -1/2

Find the exact value of the trigonometric expression when
sin(u) = − /13 and cos(v) = − 4/5. (Both u and v are in Quadrant III.)
tan(u+v)
Part of the value of sin(u) is cut off; I suspect it should be either sin(u) = -5/13 or sin(u) = -12/13, since (5, 12, 13) is a Pythagorean triple. I'll assume -5/13.
Expand the tan expression using the angle sum identities for sin and cos :
tan(u + v) = sin(u + v) / cos(u + v)
tan(u + v) = [sin(u) cos(v) + cos(u) sin(v)] / [cos(u) cos(v) - sin(u) sin(v)]
Since both u and v are in Quadrant III, we know that each of sin(u), cos(u), sin(v), and cos(v) are negative.
Recall that for all x,
cos²(x) + sin²(x) = 1
and it follows that
cos(u) = - √(1 - sin²(u)) = -12/13
sin(v) = - √(1 - cos²(v)) = -3/5
Then putting everything together, we have
tan(u + v)
= [(-5/13) • (-4/5) + (-12/13) • (-3/5)] / [(-12/13) • (-4/5) - (-5/13) • (-3/5)]
= 56/33
(or, if sin(u) = -12/13, then tan(u + v) = -63/16)

A helicopter landing pad is built on the roof of a hospital. Helicopters land inside the circular part of the pad. This part has a diameter of 50 feet.
What is the area inside the circle on the landing pad to the nearest whole number?
A
1963 feet2
B
3927 feet2
C
7854 feet2
D
15,708 feet2
Answer:
A
Step-by-step explanation:
If 50 is the diameter that thr radius is 25 and the equation to find the area of a circle is pi(r^2). So you would do pi(25^2) and that is 1963

The expressions to the correct function combination is (f. g)(x).
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that;
f(x) = 12 - 61 – 27
g(t) = 1 - 9
Now,
To match the expressions to the correct function combinations, you can substitute the values of f(x) and g(t) into the expressions and simplify. For example:
( + 5)() = (f(x) + 5)(g(t))
( + 5)() = ((12 - 6x - 27) + 5)(1 - 9t)
( + 5)() = (17 - 6x)(1 - 9t)
( + 5)() = 17 - 153t - 6x + 54xt
Therefore, by the given equation the answer will be (f. g)(x).

Suppose that Eitan rolls a fair six-sided die and a fair four-sided die simultaneously. Let A be the event that the
sum of the dice is 8 and B be the event that Eitan rolls doubles. Using the sample space of possible outcomes
below, answer each of the following questions,
What is P(A), the probability that the sum of the dice is 8?
What is P(B), the probability that Eitan rolls doubles?
What is P(A and B), the probability that the sum of the dice is 8 and Eitan rolls doubles?
Are events A and B independent?
Choose 1 answer:
A Yes, events A and B are independent events.
No, events A and B are not independent events.
Given : Eitan rolls a fair six-sided die and a fair four-sided die simultaneously. A be the event that the sum of the dice is 8 and B be the event that Eitan rolls doubles
To find : probability of event A , event B , Event A or B , Event A & B
Solution:
Six Sides Dice has { 1 , 2 , 3 , 4 , 5 ,6 }
4 Sides Dice has = { 1 , 2 , 3 , 4 }
Total possible outcome = 6 * 4 = 24
n(S) = 24
A = Sum of Dice = 8
(4 , 4) , ( 5 , 3) , ( 6 , 2)
n(A) = 3
B = Double ( means same number on each Dice )
B = ( 1 , 1) , ( 2, 2) , ( 3 , 3) , ( 4, 4)
n(B) = 4
A U B = ( 1 , 1) , ( 2, 2) , ( 3 , 3) , ( 4, 4) ( 5 , 3) , ( 6 , 2)
n (A U B ) = { 6 }
A ∩ B = { 4 , 4}
n(A ∩ B) = 1
Probability of Event A = 3/24 = 1/8
probability of Event B = 4/24 = 1/6
Probability of Event A or B = 6/24 = 1/4
Probability of Event A and B = 1/24

Answer:
And great great the owner is 44
Step-by-step explanation:
or 36 because you have to add all sides
log(x + 2) – logx =log(2x – 1) - log(3x – 12)
First note that any solution must belong to all of the intervals
x + 2 > 0 ⇒ x > -2
x > 0
2x - 1 > 0 ⇒ x > 1/2
3x - 12 > 0 ⇒ x > 4
so x must be larger than 4.
Recall that log(a) - log(b) = log(a/b). So we can rewrite
log(x + 2) - log(x) = log(2x - 1) - log(3x - 12)
log((x + 2)/x) = log((2x - 1)/(3x - 12))
Take the antilogarithm/exponential of both sides (note that the base of the logarithm doesn't matter here):
exp[log((x + 2)/x)] = exp[log((2x - 1)/(3x - 12))]
(x + 2)/x = (2x - 1)/(3x - 12)
Eliminate the fractions:
x (3x - 12) • (x + 2)/x = x (3x - 12) • (2x - 1)/(3x - 12)
(3x - 12) (x + 2) = x (2x - 1)
Expand both sides, collect terms and factorize to solve for x :
3x² - 6x - 24 = 2x² - x
x² - 5x - 24 = 0
(x - 8) (x + 3) = 0
x - 8 = 0 or x + 3 = 0
x = 8 or x = -3

A. an = 83 + 1.5(n – 1)
B. an = 83 + 1.5(n + 1)
C. an = 86 + 2(n – 1)
D. an = 86 + 2(n + 1)
The rule for the height of the tree during the nth month will be an = 83 + 1.5(n – 1). The correct option is A.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that in the third month of the study, a sugar maple tree is 86 inches tall. In the seventh month, the tree is 92 inches tall.
For option A satisfy the equation for n = 3 and n = 7,
an = 83 + 1.5(n – 1)
a₃ = 83 + 1.5(3 – 1)
a₃ = 83 + 3
a₃ =86
a₇ = 83 + 1.5(7– 1)
a₃ = 83 + ( 1.5 x 6 )
a₃ = 83 + 9
a₃ = 92
Therefore, the rule for the height of the tree during the nth month will be an = 83 + 1.5(n – 1). The correct option is A.
