16. Crayola makes 2400 crayons in 4 minutes. How many crayons can they make in 15 minut es? pls help U_U
Answer:
9000
Step-by-step explanation:
they make 600 every minute so in 15 minutes they would make 9000
Answer:
They can make 9000 crayons in 15 minutes.
Step-by-step explanation:
Figure out the ratio:
[tex]\frac{2400}{4}[/tex]
Simplify it to get the total number of crayons that they can make in one minute.
2400/4 = 600
They can make 600 crayons per minute.
Now, you should have a proportion.
[tex]\frac{600}{1}[/tex]
Now, multiply the denominator and numerator by 15 because whatever you do to the denominator you have to do to the numerator.
You should now have your answer.
[tex]\frac{9000}{15}[/tex]
Crayola can make 9000 crayons in 15 minutes.

Odd and even functions need to exhibit some sort of reflection symmetry across the x axis (i think--we are learning this rn) and the graph does not seem to show this so i believe it is neither... i could be wrong thooughh
6. An ostrich cannot fly, but it is able to run fast. Suppose an ostrich runs east for 7.95 s and then runs 161 m south, so that the magnitude of the ostrich's resultant displacement is 226 m. Calculate the magnitude of the ostrich's eastward component.
Answer:
159 m
Step-by-step explanation:
From the information given:
It was stated that if the ostrich ran towards the east direction in 7.95 s, let say the distance from the starting point is O towards the east side E, let called the distance towards the east side to be OE.
Again, the ostrich then runs in the south direction for 161 m, let the distance be OS.
Also, let the magnitude of the resultant displacement between the east direction to the south direction be ES = 226m.
We are to find, the magnitude of the ostrich's eastward component.
i.e. The distance traveled from the center to the east direction within the time frame of 7.95 s.
Using the Pythagoras rule:
ES² = OE² + OS²
226² = OE² + 161²
226² - 161² = OE²
OE² = 226² - 161²
OE² = 51076 - 25921
OE² = 51076 - 25921
OE² = 25155
[tex]OE = \sqrt{25155}[/tex]
OE = 158.60 m
OE ≅ 159 m
Thus, the magnitude of the ostrich's towards the eastward component. = 159 m.

A guppy was swimming 8 feet below the surface of the river. It swam down 6 more feet
to escape a large, hungry fish. What is the position of the guppy now relative to the
surface?
To solve the problem, Jenna subtracted 8 - 6 and came up with an answer of 2 feet. Is Jenna
correct? Why or why not?
Answer:No because once the guppy swam down 8 feet below the surface of the river the 8 is now negative since the surface of the ocean is 0 and 0-8=-8 and then he swam down 6 feet more so we have to subtract-8-6= -14 feet so the position of the guppy is now -14 feet below sea level.

The price that a company charged for a computer accessory is given by the equation 100-10x2 where x is the number of accessories that are produced, in millions. It costs the company $10 to make each accessory. The company currently produces 2 million accessories and makes a profit of 100 million dollars. What other number of accessories
produced yields approximately the same profit?
O 1.45 million
O 3.45 million
O 40 million
O 48 million
Answer: 1.45 million is your answer
Step-by-step explanation:
edge
The number of accessories produced that yields approximately the same profit as 2 million is 3.45 million. The correct option is B.
What is Revenue?
Revenue is defined as the money generated by normal business operations and is calculated by multiplying the average sales price by the number of items sold.
The profit (P) made by the company can be calculated as follows:
P = (Revenue) - (Costs)
Where Revenue = (Price per accessory) × (Number of accessories produced), and Costs = (Cost per accessory) × (Number of accessories produced).
So, using the given information, we can write:
P = (100-10x^2) x - (10x)
where x is the number of accessories produced in millions.
We know that the company makes a profit of 100 million dollars when it produces 2 million accessories, so we can set P = 100 and x = 2, and solve for the constant of proportionality k:
100 = (100-10(2)^2)(2) - (10)(2) + k
k = 200
Now, we can set P ≈ 100 again and solve for x, using k = 200:
100 = (100-10x^2)x - (10x) + 200
0 = -10x^3 + 10x^2 + 10x + 100
0 = -x^3 + x^2 + x + 10
We can solve this equation using synthetic division or by using a graphing calculator, and we find that there is a root between x = 3 and x = 4.
Therefore, the number of accessories produced that yields approximately the same profit as 2 million is 3.45 million, which is option B.

Ann took a taxi home from the airport. The taxi fare was $2.10 per mile, and she gave the driver a tip of $5. Ann paid a total of $49.10.
Write an equation to determine the distance in miles (x) between the airport and Ann's home
Find the distance between the airport and Ann's home.
Answer:
$2.10x + 5= $49.10
x=21
Step-by-step explanation:
the x is used for a variable that changes and in this case the mph changes which lead x being the amount of miles that they had drove which at the end ends up multi. with the $2.10 . as for the 5 it was an initial as in it doesn't change.
for the second part
you subtract 5 from each side so you have the total of 2.10x= 44.10 then u divide 2.10 from each side and that will give you x = 21

Which values represent solutions to the equation?
Tangent (StartFraction 3 pi Over 4 EndFraction minus 2 x) = negative where x Is an element of [0, Pi]
The solution set for the given expression is {0, π/2, π}.
Which values of x are solutions for the given expression?Here we have the expression:
[tex]tan(\frac{3\pi}{4} -2x) = -1[/tex]
First, we know that:
[tex]tan(\frac{3\pi}{4}) = -1[/tex]
So, if x = 0, the equation is true, which means that x = 0 is a solution.
And the tangent function as a period of pi.
This means that:
tan(x) = tan(x - π) = tan(x - 2*π) etc.
Then if x = π/2 and x = π also are solutions, so we conclude that the solution set is:

Answer:
1.3°F * 10 = 13°F

Step-by-step explanation:
Given that:
Temperature on the ground = - 2.8°F
Change in temperature per 1000 ft rise = 1.3°F
Change in temperature after the plane ascends 10000 ft
Change in temperature per 1000ft rise * (10000/1000)
1.3°F * 10 = 13°F
B.) Temperature at 10,000 feets
Temperature on ground + change in temperature at 10,000ft

The correct measure of other angle should be less than 49°.
It is given that a student measures that one acute angle has a measure of 41° and other acute angle has measure of 139°.
We have to find out that while finding measure of other angle what error might student have made.
What do you mean by an acute angle ?
An acute angle is an angle which measures less than 90 degrees. i.e., ∠45°.
As per the question ;
1st angle = 41 °
we know that sum of acute angles of a triangle should be less than 90°.
Let's assume other angle be x.
So ;
x + 41° < 90°
x < 90° - 41°
x < 49°
So , the student had measured ∠2 wrongly because sum of acute angles of a triangle should be less than 90°.
Thus , the correct measure of other angle should be less than 49°.

Find the total cost to the nearest cent.
$24 shirt; 6% tax
Answer:
The tax itself would be $1.44 and the total would be $25.44
Step-by-step explanation:
You multiply 24 by 6% (0.06) and get 1.44 then you add that to the original cost (24) and get $25.44.
Total cost will be $25.44.
What is Percentage?
A relative value indicating hundredth part of any quantity is called percentage.
Given that;
Cost of shirt = $24
Tax = 6%
Now,
The value of tax = 24 × 6%
= 24 × 6/100
= 1.44
So, Total cost = $24 + $1.44
= $25.44
Thus, Total cost will be $25.44.
