solve for the missing side and round to the nearest tenths place
Answer:
A. 22.5
Step-by-step explanation:
Apply Trigonometric function.
Reference angle = 64°
Opposite side to 64° = x
Hypotenuse = 25
Apply SOH:
Sin 64 = Opp/Hyp
Sin 64 = x/25
25 × Sin 64 = x
22.4698512 = x
x = 22.5 (nearest tenth)

One jar of jelly costs $
Answer: $3.75
Step-by-step explanation:
First you would have to find the unit rate.
$15 / 4 jars of jelly = $3.75
Therefore, 1 jar of jelly = $3.75
Answer:
the answer is $3.75
Step-by-step explanation:
15 ÷ 4= 3.75
to verify your answer multiply
3.75 × 4= 15

The cost of one pen when pens are priced at 5 for p dollars
I really need help on this
Answer:
$1
Step-by-step explanation:
If 5 pens = $p, then 1 pen = $p/5.
But because 5 pens = $p, it would be the same thing as 5 = p because you just take off the labels.
So p = 5 and one pen would be:
$p/5 = 1
5/5 = 1
1 = 1
A school district is considering moving the start of the school day at Groveland High from 8:00 a.m. to 9:00 a.m. to allow students to get more sleep at night. They want to estimate how many more hours of sleep teens get if their school starts at 9:00 a.m. compared to teens whose schools start at 8:00 a.m. The district takes random samples of 50 of students from Groveland High and 39 students from Phillips High School, which starts at 9:00 a.m., and surveys them about their sleep habits. The sample mean number of hours of sleep per student at Groveland is 7.1 hours, and the standard deviation is 1.7 hours. At Phillips, the sample mean is 8.3 hours of sleep, with a standard deviation of 1.9 hours. What is the 90% confidence interval for the difference in mean hours of sleep for students at the two high schools
Answer:
The answer is "[tex]\bold{(7.1-8.3) \pm 1.665 \sqrt{\frac{(1.7)^2}{50}+\frac{(1.9)^2}{39}} }\\\\[/tex]"
Step-by-step explanation:
Given values:
[tex]\bar{x_1}=7.1\\\\\bar{x_2}=8.3\\\\s_1=1.7\\\\s_2=1.9\\\\n_1=50\\\\n_2=39[/tex]
Using formula:
[tex]\to (\bar{x_1} -\bar{x_2}) \pm t \sqrt{\frac{(s_1)^2}{n_1}+\frac{(s_1)^2}{n_2}} \\\\[/tex]
Put the values in the above formula:

What is the height of the cone if the volume is 12 pie ft ? And radius is 3ft
Answer:
Step-by-step explanation:
Problem One
V = pi r^2 h
V = 3.14 * (4/2)^2 * 6
V = 3.14 * 4 * 6
V = 75.36
However, that is not the answer. The answer is 1/3 of that amount.
V1 = 1/3 * 75.36
V1 = 25.12
Problem 2
V= `12 pi
r = 3 feet
Formula
V = 1/3 pi r^2 h
12* pi = 1/3 * pi * 3^2 * h Cancel the pi s.
12 = 1/3 * 9 * h
12 = 3 h Divide by 3
12/3 = h
h = 4

Tom has 2 1/2 times as many cards as Harry. Together they have 98 cards. How many cards do they each have?
Answer:
Tom has 70 cards, and Harry has 28 cards.
Step-by-step explanation:
Let h = number of cards Harry has.
Then the number of cards Tom has is 2 1/2 * h = 2.5h.
Together they have 2.5h + h = 3.5h number of cards.
Together they have 98 cards.
3.5h = 98
h = 98/3.5
h = 28
Harry has 28 cards.
Tom has 2.5h = 2.5 * 28 = 70
Answer: Tom has 70 cards, and Harry has 28 cards.

Mensualmente el número de árboles talados aumenta en un 9% respecto del mes anterior. Si este mes hay 85.000 árboles talados, ¿cuántos árboles talados habrá, aproximadamente, en 6 meses más?
Answer:
FV= 639.483 arboles
Step-by-step explanation:
Dada la siguiente información:
Cantidad de árboles talados (A)= 85.000
Proporción de crecimiento (g)= 9% mensual
Cantidad de meses (n)= 6
Para calcular el total de árboles talados en 6 meses, tenemos que usar la siguiente formula:
FV= {A*[(1+i)^n - 1]} / i
A= cantidad de árboles talados
i= proporcion de crecimiento
n= cantidad de meses
FV= {85.000*[(1.09^6) - 1]} / 0.09
FV= 639.483 arboles
Ahora, la cantidad de árboles que se talaran en el sexto mes:
FV= PV*(1+i)^n
FV= 85,000*(1.09^6)
FV= 142.553

1.give the sequence 8.5.2.-1,...at what term will the number become -25? A.11th term B.10th term C.12th term D.20th term 2.which of the following is an algebraic esprression? A.3+5 B.n-1-14 C.3+5=8 D.x=53 3.what is the sum of the first 5 even numbers? A.30 B.20 C.10 D.50
Answer: 1. C(12) 2. B(n-1-14) 3. A(30)
Step-by-step explanation: For number one the nth term with common difference d and first term a is a+(n-1)d=nth term, plug in the values you have and solve for n to get 12. For number 2 an algebraic expression has a variable and a constant but doesn't have an equal sign. So it is B. For number three just add them up. Hope this helped!

Find the probability that a
randomly
selected point within the circle falls
in the red shaded area.
60°
60°
r= 4 cm
[? ]%
Round to the nearest tenth of a percent.
Answer: 33.3%
s Step-by-step explanation: The combined arc length of the red area is 120, which is 1/3 of 360, the full arc. So the probability is 1/3, or 33.3%. Hope this helps!
The probability that a randomly selected point within the circle falls
in the red shaded area will be 33.33%.
What is probability?Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favorable outcomes / Number of sample
Given that the shaded red sector has an angle of 60 degrees and the radius of the circle is 4 cm. The probability will be calculated as:-
The formula for a circle's sector's area is (Ф/360°) x π(r²), where r is the circle's radius and is the sector's angle.
Area of shaded region = (Ф/360°) x π(r²),
Area of shaded region = ( 60 / 360 ) x π (4²)
Area of shaded region = 8.377 square cm
Total shaded area = 2 x 8. 377 = 16.75 square cm
Total area of circle = π (4²) = 50.265 square cm
The probability is calculated by the formula below:-
Probability = Number of favorable outcomes / Number of sample
Number of favorable outcomes = 8.377
Number of sample = 50.265 square cm
Probability = 8.377 / 50.265 = 0.3333 = 33.33%
Therefore, the probability that a randomly selected point within the circle falls in the red-shaded area will be 33.33%.
