11. Alicia and three friends are making a video
to post online. The three friends all made
video segments of equal length, and Alicia's
video segment is less than 5 minutes long.
Let s represent the length of each of the
friend's segments. Write an inequality to
represent the length l of the full video.
Al> 3s + 5 © e> 3s + 5
Be<3s + 5 D &< 35 +5
Answer:
L < 3s + 5
Step-by-step explanation:
Given that:
Video length of all 3 friend are equal
Let the length of the video made by each friend = s
Length of video of all 3 friends = 3s
Alicia's video segment is less than 5 minutes long
Hence the length L of the full video :
L = (Length of video of all 3 friends + Alicia's video segment)
Since Alicia's < 5
Hence full video length :
L < 3s + 5

i need help please help
Answer:
The answer is 46 degrees.
Step-by-step explanation:
To find angle RPQ, subtract 108 from 180 because a straight line equals 180 degrees.
108 - 180 = 72
A triangles angles add up to 180. We have two of them. To find the third angle, subtract the two angles from 180.
180 - 72 - 62 = 46.

Answer:
y = 2x - 22
Step-by-step explanation:
y = 2x - 8
it is the form of y = mx + c
to be parallel the m should be the same ..
so the equation m = 2
znd it is given that it is passing (11,0) so that the equation should satisfy the point ( 11,0)
y = mx + c
y = 0 , m = 2 , x = 11
0 = 2 ( 11 ) + c
c = -22
so the required equation for the parallel line is
y = 2x - 22

Answer:
0.4 of lemon is being used for one cup
Step-by-step explanation:
12 divided by 3 is 4 which is more than 3 meaning we need to try and make it smaller which is why the 4 was carried down by one row making 0.4

Find the value of x. (Hint: The sum of the angles in
a triangle is 180 degrees.)
The value of x is degrees.
Answer:
look below
Step-by-step explanation:
Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

The function p above models the total price p( m ), in dollars, of streaming m movies per month from an online movie subscription service. The subscription service charges an $8 monthly fee plus an additional fee per movie streamed. Which of the following is the best interpretation of p( 10) in this context?
A) The total price for streaming 1 movie in a month is $10.
B) The total price for streaming 2 movies in a month is $10.
C) When 10 movies are streamed in a month, the total price that month is $18.
D) When 10 movies are streamed in a month; the total price that month is $28.
9514 1404 393
Answer:
D) When 10 movies are streamed in a month; the total price that month is $28.
Step-by-step explanation:
Using the function definition, put 10 where you find m, then evaluate:
p(10) = 2(10) +8 = 20 +8
p(10) = 28
The function definition tells you this (28) is the price of streaming 10 movies in a month.

Hi there!
[tex]\large\boxed{tan\text{ } (\frac{-\pi }{6})}[/tex]
**Recall that tangent is Opposite / Adjacent**
tan (5π / 6) according to the unit circle equals -1 / √3. We can go through each choice and eliminate:
tan (-5π / 6) is in the third quadrant which would mean that the value would be positive 1 / √3. This choice is incorrect. tan (7π / 6) is the same as tan (-5π / 6), which is positive 1 / √3. This choice is incorrect.cot (5π / 6) is the reciprocal of tan 5π / 6, which is incorrect.tan (-π / 6) is equal to -1 / √3. This choice is correct.Therefore, the correct choice is tan (-π / 6).
How many solutions does this equation half? x=x+9
Answer:
I think it is 0 solutions
Step-by-step explanation:
it should be 0 because no matter what number you substitie x for, the right side will always be 9 higher than it, so x never equals x

3 < y ⩽ 7 where y is an integer Write down all the possible values of y
add 4 i guess. i dont really know
Answer: 4, 5, 6, 7
Step-by-step explanation:
Let’s break this apart into 3 < y and y <= 7.
We can rewrite 3 < y as y > 3, and we also have that y <= 7.
This is equivalent to the verbal expression y is greater than 3 and less than or equal to 7.
We can then conclude that y must be between 4 (since that is the first number greater than 3) and 7 (since y includes 7).
Therefore, y can be 4, 5, 6, or 7!
Hope this helps! :)

What is the volume of a triangular pyramid that has a base area of 8.2 square centimeters and a height of 4
centimeters? Label the answer correctly and round to the nearest tenth of a cubic centimeter
Answer:
[tex]\boxed {\boxed {\sf V \approx 10.9 \ cm^3}}[/tex]
Step-by-step explanation:
The volume of a triangular pyramid can be found using the following formula:
[tex]V=\frac{1}{3} A_b\times h[/tex]
Basically, we have to multiply 1/3, the height, and the base area.
We know that the base area is 8.2 square centimeters and the height is 4 centimeters.
[tex]A_b=8.2 \ cm^2 \\h= 4 \ cm[/tex]
Substitute the values into the formula.
[tex]V=\frac{1}{3} (8.2 \ cm^2)\times (4 \ cm)[/tex]
Multiply 8.2 square centimeters and 4 centimeters.
8.2 cm² * 4 cm= 32.8 cm³[tex]V=\frac{1}{3} (32.8 \ cm^3)[/tex]
Multiply 1/3 and 32.8 cubic centimeters.
[tex]V= 10.9333333 \ cm^3[/tex]
Round to the nearest tenth.
The 3 in the hundredth place tells us to leave the 9 in the tenth place.
[tex]V \approx 10.9 \ cm^3[/tex]
The volume of the triangle pyramid is about 10.9 cubic centimeters.
A family has two cats named Gordo and Flaco. Gordo weighs 15 pounds and Flaco weighs 8 pounds. A cat’s weight is classified as unhealthy if the weight is located in the top 5% or bottom 5% of all cat weights. The distribution of cat weights is approximately normal with mean 9.5 pounds and standard deviation 1.5 pounds. Which of the following is the best description of Gordo’s and Flaco’s weights?
Answer:
Gordo's weight = 15 pounds
It is outside the healthy weight range and is in the top 5% of weights of cats.
Gordo's weight makes Gordo unhealthy.
Step-by-step explanation:
μ = mean weight = 9.5 pounds
σ = standard deviation = 1.5 pounds
This is a normal distribution problem
We first calculate the limit of the bottom 5% of weights
Let the z-score for this limit be z'
P(z < z') = 0.05
From the normal distribution table,
z' = -1.645
And the limit for the top 5% which is z" = 1.645.
The weight that corresponds to these scores are then calculated.
Standardized scores are given as
z = (x - μ)/σ
So,
z' = (limit for the bottom 5% - μ)/σ
-1.645 = (limit for the bottom 5% - 9.5)/1.5
limit of the bottom 5% = (-1.645)(1.5) + 9.5 = 7.033 pounds
z" = ( (limit for the top 5% - μ)/σ
1.645 = (limit for the top 5% - 9.5)/1.5
limit of the bottom 5% = (1.645)(1.5) + 9.5 = 11.968 pounds
Therefore the healthy weight range for cats is (7.033 < x < 9.968)
Gordo's weight = 15 pounds
It is outside the healthy weight range and is in the top 5% of weights of cats.
Gordo's weight makes the cat unhealthy.
Flaco's weight = 8 pounds
Flaco's weight lies in the healthy weight range for cats. Hence, Flaco is a healthy cat.
An astronaut on the moon throws a baseball upward. The astronaut is 6 ft 6 in tall, and the initial velocity of the ball is 40 ft per sec. The heights of the ball in feet is given by the equation
S = -2.7t^2+40t+6.5, where t is the number of seconds after the ball was thrown.
After how many seconds is the ball 18 ft above the moon's surface?
Answer:
t = 0.293 s and 14.52 s
Step-by-step explanation:
The heights of the ball in feet is given by the equation as follows :
[tex]S = -2.7t^2+40t+6.5[/tex]
Where t is the number of seconds after the ball was thrown.
We need to find is the ball 18 ft above the moon's surface.
Put S = 18 ft
[tex]-2.7t^2+40t+6.5=18\\\\-2.7t^2+40t=18-6.5\\\\-2.7t^2+40t-11.5=0[/tex]
It is a quadratic equation. Its solution is given by :
[tex]t=\dfrac{-40+\sqrt{40^{2\ }-4\left(-2.7\right)\left(-11.5\right)}}{2\left(-2.7\right)},\dfrac{-40-\sqrt{40^{2\ }-4\left(-2.7\right)\left(-11.5\right)}}{2\left(-2.7\right)}\\\\t=0.293\ s,14.52\ s[/tex]
So, the ball is at first 0.293 s and then 14.52 s above the Moon's surface.
