Hi there!
[tex]\large\boxed{42\pi \text{in or } 131.88 \text{in}}[/tex]
Use the equation C = dπ to calculate the circumference:
d = diameter
C = circumference
C = 42 · π = 42π in, or 131.88 in (π ≈ 3.14)
8p(-3p^2+6p-2) hellpppppppp
-16p was my answer after simplifying it
Answer:
120p - 16p = 104p
Step-by-step explanation:
-3p x -3p = 9p + 6p = 15p x 8p = 120p
8p x -2 = -16p
120p - 16p = 104p
Please wait for more responses if needed thank you.
A company introduced a much smaller variant of its tablet, known as the tablet junior. Weighing less than 11 ounces, it was about 50% lighter than the standard tablet. Battery tests for the tablet junior showed a mean life of 10.25 hours. Assume that battery life of the tablet junior is uniformly distributed between 7.5 and 13 hours.
(a)
Give a mathematical expression for the probability density function of battery life.
f(y) =

What is the probability that the battery life for a tablet junior will be 10.5 hours or less? (Round your answer to four decimal places.)
(c)
What is the probability that the battery life for a tablet junior will be at least 11.5 hours? (Round your answer to four decimal places.)
(d)
What is the probability that the battery life for a tablet junior will be between 8.5 and 10.5 hours? (Round your answer to four decimal places.)

[tex]x-5\leq 12[/tex]
You add 5 to each side
[tex]x\leq 17[/tex]
This inequality will be correct if x is less than or equal to 17. Meaning any number less than 17 and including 17 will make the equation correct. For this reason you pick the one with a filled circle. The answer is H
A quarter falls off a building that is 144
feet tall. If the equation for height as a
function of time is
h(t) = -16t2 + initial height where t is
time in seconds and h(t) is height in
feet, how many seconds will it take for
the quarter to hit the ground?
Answer:
3 seconds
Step-by-step explanation:
Initial height = 144 feet
t = Time taken
The equation of the height from the ground is
[tex]h(t)=-16t^2+\text{Initial height}[/tex]
The time taken to reach the ground is needed. Here the ground is taken as reference so [tex]h(t)=0[/tex]
[tex]0=-16t^2+144\\\Rightarrow -144=-16t^2\\\Rightarrow t=\sqrt{\dfrac{144}{16}}\\\Rightarrow t=3\ \text{s}[/tex]
So, time taken by the quarter to reach the ground is 3 seconds.
What is the area of a square if the half of the diagonal is 6
Answer:
72
Step-by-step explanation:
Cut the square into two equal triangles along the diagonal
You know that half of the diagonal is 6 so multiply that by 2 to get 12 which is the hypotenuse of your triangles
Then use the pythagorean theorem to solve for the sides
a^2 + b^2 = 12^2
a^2 + b^2 = 144
Since the original shape was a square both sides a and b are equal
a^2 = b^2
a^2 + a^2 = 144
2a^2 = 144
a^2 = 144/2
a^2 = 72
a = [tex]\sqrt{72}[/tex]
Since a = b then a = [tex]\sqrt{72}[/tex] =b
Multiply both sides a and b to get the area of the square
[tex]\sqrt{72}[/tex] * [tex]\sqrt{72}[/tex] = 72
A container is in the shape of a right rectangular prism. Hayden wants to put a stick in the container.
What is the length in inches of the longest stick that will fit in the container
Answer:
13 in.
Step-by-step explanation:
First figure out the length of the diagonal of the base.
3²+4²=c²
9+16=c²
25=c²
√25=c
c=5
Now we can figure out the stick using the same method.
5²=12²=c²
25+144=c²
169=c²
√169=c
c=13
Given that ABCD ~ EFGH, find the value of x
Answer:
x = 8
Step-by-step explanation:
Recall: Ratio of the corresponding side lengths of two similar figures are equal.
Therefore,
EF/AB = GH/CD
6/4 = 12/x
Cross multiply
6*x = 12*4
6x = 48
Divide both sides by 6
6x/6 = 48/6
x = 8

5. During the day a person consumes 360
calories from fruit. How many calories does
this person consume in their daily diet?
A. 1,600
B. 2,300
C. 2,400
D. 2,600
Answer: C :2400
Step-by-step explanation:
Part over whole and percent over 100 you put 15 as your percent and 100 over it then you put 360 as your part then you multiply 360x100=36,000 you divide that with 15 and you get 2,400

Is the expression true?
Answer:
Step-by-step explanation:
3(4)+2(8)=7(4)+4(8)
12+16=28+32
28=60
Therefore, the expression is not true because they are not equal to each other
Please mark answer as brainliest
Answer:
3(4) + 2(8) = 7(4)+ 4(8)

Answer:
5. (d) 8
6. (c) 120°
Step-by-step explanation:
5. OC is a radius, just like BO is. The angle at B is a right angle, so the Pythagorean theorem can be used to find BO.
AO² = BO² +BA²
BO² = AO² -BA² = 17² -15² = 289 -225 = 64
BO = CO = √64 = 8

6. The measure of arc IK is the same as the measure of the central angle. If we name the circle center X, then arc IK = ∠IXK = ∠HXL because those angles are vertical angles.
arc IK = 120°

A researcher is selecting lab rats for her experiment. She assigns each rat a number and picks numbers out of a hat while blindfolded. The pool of rats from which she is drawing participants is composed of the following: 23 male albino rats 21 male spotted rats 35 female albino rats 11 female spotted rats If she reaches into the hat twice, what is the probability of choosing a male albino rat and then either a female albino rat or a male spotted rat
Answer: [tex]\dfrac{76}{89}[/tex]
Step-by-step explanation:
The pool of rats from which the researcher is drawing participants is composed of the following:
23 male albino rats
21 male spotted rats
35 female albino rats
11 female spotted rats
Total rats = 23+21+35+11 =90
[tex]P(male\ albino)=\dfrac{23}{90}[/tex]
After drawing first rat , total rats remained = 89
[tex]P(\text{either a female albino rat or a male spotted rat})=\dfrac{35+21}{89}=\dfrac{76}{89}[/tex]
The probability of choosing a male albino rat and then either a female albino rat or a male spotted rat = [tex]\dfrac{76}{89}[/tex]
