To find the portion of the beaker filled, consider the total volume of the beaker and the volume up to which it is filled. Perform division and multiply by 100 to get the percentage filled.
Explanation:To determine the portion of the beaker filled, one must first understand the metrics of a beaker. A beaker is a cylindrical container with a flat bottom used to measure liquids. The scale etched on the side of the beaker represents the volume it contains. Suppose the total volume from the bottom up to the line of liquid is 300 mL and the total capacity of the beaker is 500 mL. By performing a simple division, 300 mL divided by 500 mL=0.6. Therefore, approximately 60% of the beaker would be filled. This is an approximate measure and for more accuracy, one should use a graduated cylinder.

At hockey practice, Talia took 35 shots, and made 60% of them. She had hoped to make 25 shots. By how many shots did she fall short of her goal?
Answers
Answer:
4 goals short
Step-by-step explanation:
To find how many shots Talia made - multiply the total number of shots (35) by 60% (or 0.60)
35*.60 = 21 shots made
Subtract her goal (25) by the shots actually made (21)
25-21 = 4 shots from her goal
there are 150 more passenger cars than trucks on the highway. for every 10 passenger cars there are 7 trucks. how many trucks are on the highway?
Answers
Answer:
500
Step-by-step explanation:
Given: P = 150 - T where P is passenger cars and T is trucks
10P = 7T ⇔ P = [tex]\frac{7T}{10}[/tex]
Plug in equation 2 into equation 1:
[tex]\frac{7T}{10}[/tex] = 150 - T
Solving for T, we get 500
Answer:
There would be 500 passenger cars and 350 trucks.
Step-by-step explanation:
In order to find this, we need to create a system of equations. Start by making the number of passenger cars as x and the number of trucks at y. Now the first equation can be the difference of the two.
x - y = 150
The second equation can make use of the proportion. If we multiply by the opposites we'll get the difference of 0.
7x - 10y = 0
Now we multiply the first equation by -10 and add together to solve for x.
-10x + 10y = -1500
7x - 10y = 0
-------------------
-3x = -1500
x = 500
Now we can find the amount of trucks by using either equation.
x - y = 150
500 - y = 150
-y = -350
y = 350

 Question:
The time required for a skilled worker to produce x shirts is given by the function T(x) = 4x + 2, where T is measured in hours. The salary the she is paid is given by the function S(T) = 15T, where S is measured in dollars.
A. If the worker produces 18 units, what will she be paid?
B. How many units would the worker need to produce to be paid $3,030?
Answers
Answer:
A) The worker is paid S= $ 1110 for producing 18 units.
B) The worker is paid $3,330 for producing x= 50 units.
Step-by-step explanation:
a) given x = 18 units
Time required T(x) = 4x+2
= 4(18)+2
= 72 +2
= 74 hrs
Amount paid S(T) = 15 T
= 15 ( 74) = $ 1110
b) Since S is given, S= $3,030
S(T)= 15 (T)
3030 /15= T
202 hrs= T
Now, we can find x:
T(x) = 4(x) +2
202 = 4x + 2
202-2 = 4x
200 / 4 =x
50 = x
so, worker produces 50 units.
george works for a garden center where is is paid a salary of 350 per week plus a commission of 6% of the amount of merchandise that he sells. Last week his sales totaled 1,850. What was his gross pay?
Answers
Answer: His gross pay is $461.
Step-by-step explanation: George’s gross pay consists of two parts, his salary and his commission. His salary is $350, regardless of how much he sells. His commission is 6% of the $1,850 in sales that he made.
First, calculate the amount of commission = .06 x $1,850 = $111
$350 + $111 = $461

A. Likely
B. Unlikely
C. Impossible
D. Certain
Answers
Answer:
C
Step-by-step explanation:
Since there are no blue cards, the probability that you'd draw one is 0/12, which means that there is no chance you'll draw one.
It is impossible to get blue cards. Then the correct option is C.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
There are 4 red cards and 8 black cards in a bag.
In the bag, the number of blue cards will be zero.
Thus, it is impossible to get blue cards. Then the correct option is C.

[tex]cos(x+\pi )^{2} = sinx[/tex]
Answers
Answer:
Please, refer to the images below
Step-by-step explanation:
We need to solve for x in the equation
cos (x+ pi) ^2 = sin (x)
cos (x+ pi) = - cos(x)
(-cos (x)) * (-cos (x)) = sin(x)
cos(x) ^2 = sin(x)
We know that
cos(x) ^2 + sin(x) ^2 = 1
cos(x) ^2 = 1 - sin(x) ^2
1 - sin(x) ^2 = sin(x)
sin(x) ^2 + sin (x) -1 = 0
Let A = sin(x)
A^2 + A - 1 = 0
(solutions attached in picture 1)
This means that
x = arcsin(A)

John deposited $2,860 in a bank that pays 9% interests, compounded monthly. Find the amount he will have at the end of 3 years?
Answers
Answer:
The amount he will have at the end of 3 years is $3742.73
Step-by-step explanation:
* The formula for annual compound interest is:
A = P (1 + r/n)^(nt)
Where:
A = Total money after t years
P = the investment amount (the initial deposited amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested
∵ P = $2860 ⇒ deposited
∵ r = 9% = 9/100 = 0.09 ⇒ annual rate
∵ n = 12 ⇒ compounded monthly
∵ t = 3 years
∴ A = 2860(1 + 0.09/12)^(12 × 3)
∴ A = 2860(1.0075)^36 = $3742.73
* The amount he will have at the end of 3 years is $3742.73
Answer:
The amount he will have at the end of 3 years = $3742
Step-by-step explanation:
Formula for compound interest
A = P[1 + R/n]^nt
A - Amount
P - Principle amount
R - rate of interest
n - Number of times in which the amount compounded
t - Number of years
To find the amount
Here,
P = $2,860, R = 9% = 0.09
n = 12 and t = 3 years
A = P[1 + R/n]^nt
=2860[1 + 0.09/12]^(12*3)
= 2860[1 + 0.0075]^36 = 3742.7257 ≈ $3742

Hello there! An inequality modeling this could be x > 5.
When setting up this equation, we can use x to model the number of cookies that Sue has.
Remember that these are the symbols we use to represent inequalities:
< - greater than
> - less than
≤ - greater than or equal to
≥ - less than or equal to
Since the number of cookies Sue has is greater than 5 (but not equal to), we use the symbol.
We can represent her having x amount of cookies, which is more than 5, like this: x > 5,

If 1 black circle and 2 white circles equal 18, we can subtract 10 and get left with 2 white circles worth 8, which means a white circle is 4. A white circle minus a square is 2, which means a square is 2. So we put this all together and get 16.

the probability that the roll of a six-sides die will be either even or odd is 1/2 or 50%
The probability of a six-sided die will be either even or odd is 1/2.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
A die is rolled once.
The sample space = {1, 2, 3, 4, 5, 6}
