Answer:
The maximum temperature will be of 85 degrees, on July 15.
Step-by-step explanation:
Sine function:
The sine function oscilates between -1 and 1, and it's maximum value is:
[tex]\sin{(\frac{\pi}{2})} = 1[/tex]
y=60+25sin(pi/6)t
The maximum value will occur when [tex]\sin{(\frac{\pi t}{6}}) = 1[/tex], and it will be of 60 + 25 = 85 degrees.
When will it occur?
First we find the value of t for which the value inside the function sine is [tex]\frac{\pi}{2}[/tex]. So
[tex]\frac{\pi t}{6} = \frac{\pi}{2}[/tex]
[tex]\frac{t}{6} = \frac{1}{2}[/tex]
[tex]2t = 6[/tex]
[tex]t = \frac{6}{2} = 3[/tex]
That is the number of months after April 15, which is 3 months. So July 15.
Find the surface area of each figure to the nearest tenth.
Answer:
A≈471.24 is the surface area of the cylinder
58m^2 is the surface area of the triangular prism
Step-by-step explanation:
Solution
A=2πrh+2πr2=2·π·5·10+2·π·52≈471.2389
Triangle area formula
area = 0.5 * b * h , where b is the length of the base of the triangle, and h is the height/altitude of the triangle.
4(2.5)+8(6)
10+48=58m^2

mmm answer is 139.5 (C)
7x4.5=31.5
12x9=108
108+31.5=139.5
Answer:
A=139.5cm^2
Step-by-step explanation:
12x9=108---->Area of the rectangle A=l x w
9x7=63 divided by 2=31.5--->Area of the triangle A=1/2 (b x h)
108+31.5=139.5cm^2

Given the set of integers 1 − 20 , what is the probability of selecting a number that is divisible by 7 ?
The probability of selecting a number that is divisible by 7 is [tex]\frac{1}{10}[/tex].
What is probability?Probability deals with finding out the likelihood of the occurrence of an event.
It measures the chance of an event happening and is equal to the number of favorable events divided by the total number of events.
The value of probability ranges between 0 and 1, where 0 denotes uncertainty and 1 denotes certainty.
Given
Set of integers = 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20
The probability of selecting a number that is divisible by 7 :
We all know the 7 multiples less than 20 : 7, 14
There are 2 numbers that are divisible by 7 in the set of integers 1 - 20
Therefore, Number of favorable outcomes n(E) = 2
Total number favorable outcomes n(S) = 20
Probability is the ratio of number of favorable outcomes to total number of favorable outcomes.
[tex]P(E) = \frac{n(E)}{n(S)}[/tex]
[tex]P(E) = \frac{2}{20} =\frac{1}{10}[/tex]
Hence,
The probability of selecting a number that is divisible by 7 is [tex]\frac{1}{10}[/tex].

Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
Let's use CAH 1st , on the Lenovo building, b/c we have they Hypotenuse (Hyp) and an angle and we want to know the other side of the Lenovo building
Cos(30) = x/294
294*Cos(30) = x
254.611 = x
Sin(30) = y / 294
294*Sin(30) = y
147 = y
perimeter = 147+254.611+294
perimeter Lenovo = 695.611 feet
For Asus building
hyp = sqrt [ ( 144.5*[tex]\sqrt{2}[/tex])^2 + 144.5*[tex]\sqrt{2}[/tex])^2 )]
hyp = 289
perimeter = 289+144.5*[tex]\sqrt{2}[/tex]+144.5*[tex]\sqrt{2}[/tex]
perimeter Asus = 697.7077
The difference of the two buildings is
697.7077 - 695.611 =2.09671 feet
the difference is 2.10 feet ( rounded to nearest 100th)

She has 12 watermelons, 30 pears, and 42 apples
For each basket Kerra makes they must have the same number of fruit.
She must use all the fruit.
What is the greatest number of baskets that Kerra can make?
A. 93
B. 57
C. 132
D. 123
Answer:
B
Step-by-step explanation:
The interior angles of a triangle always add up to 180 degrees.
We have two angles already and they add up to 60+63=123 degrees
180-123=57
so the remaining angle is 57 degrees
9514 1404 393
Answer:
D. 123°
Step-by-step explanation:
The external angle is equal to the sum of the remote internal angles.
m∠1 = 60° +63°
m∠1 = 123°

Answer:
A. g(x) = √(x -5), x ≥ 5
Step-by-step explanation:
You can use the definition of an inverse function to solve for g(x).
x = f(g(x))
x = (g(x))^2 +5
x -5 = (g(x))^2 . . . . . subtract 5
√(x -5) = g(x) . . . . . take the square root
The radical contents cannot be negative, so this is only defined for x-5 ≥ 0, or x ≥ 5.
g(x) = √(x -5), x ≥ 5

Three methods for teaching mathematics to first graders are to be compared. Ten students are
randomly assigned to each of the methods, and the score on a quiz is recorded. What are the
response and treatment for this experiment?
Answer: The three methods are the treatments and the response is the score achieved on the quiz.
Step-by-step explanation:
The three techniques are the treatments, and the results are the final score.
what is response variable in the experiment?
The researcher predicts that a variable will change if the controlled variable changes; this variable is known as a responsive variable. A dependent variable is another name for a responsive variable.
Solution:
Three methods are assigned for teaching mathematics.
Randomly ten students are assigned to each of the method.
There scores are then recorded on a quiz.
It is clear that the response will be the score card of the students either scoring high marks or not being able to clear it.
And the treatments are three for if the student is not able to understand any of the method.
Hence the three methods serve as treatments, and the outcomes determine the final grade.

Find the probability of a choosing a student that is taking a foreign language, given that the student is playing a sport using the Venn Diagram below.
Answer:
7/25
Step-by-step explanation:
In simpler words, the problem wants us to find the probability of choosing a student that both play a sport and takes a foreign language.
To find this, we need to locate the intersection in the Venn diagram which is
14.
The intersection represents the number of students that both play a sport and take a foreign lang.
We have our favorable outcomes of 14.
Our total outcomes can be found by adding all the numbers like so:
23+14+10+3=50
The theoretical probability theorem is:
Number of favorable outcomes/number of total outcomes.
So our answer is 14/50, or simplified as 7/25!
