Write the equation that can be used to find the number of sales Luke made this week. Represent the number of sales as x and don't use any $ symbols.
luke works at a store and earns a fixed amount of $191 plus $16.55 per sale. Noah works at a different store and earns a fixed amount of $573 plus $49.65 per sale. They both made the same number of sales, but Luke earned
1/3 as much money as Noah this week.
An equation that can can be used to find the number of sales Luke made this week is; 191 + 16.55x = ¹/₃(573 + 49.65x)
How to Solve Equation Word Problems?
We are told to represent the number of sales as x.
Now, Luke works at a store and earns a fixed amount of $191 plus $16.55 per sale. This is represented as; 191 + 16.55x
Noah works at a different store and earns a fixed amount of $573 plus $49.65 per sale. This is represented as; 573 + 49.65x
We are told that they both made the same number of sales but Luke earned a third of what Noah earned. Thus;
191 + 16.55x = ¹/₃(573 + 49.65x)
An equation that can can be used to find the number of sales Luke made this week is;
191 + 16.55x = ¹/₃(573 + 49.65x)

& BD =
A
D
E
The value for x is [Select]
The value for BD is [Select]
The value of x and BD are 29 and 62
How to determine the lengthsFrom the diagram shown, we can see that AC and BD are diagonals of the rectangle
It is important to note that the diagonals of a rectangle are equal
Then,
AC = BD
4x - 54 = 33 + x
collect like terms
4x - x = 33 + 54
Add/ subtract like terms
3x = 87
Make 'x' the subject
x = 87/ 3
x = 29
But BD = 33 + 1x = 33 + 1(29) = 33 + 29 = 62

1. What do the terms 50, 312t, and -16? tell us about the cannonball?
2. Use graphing technology to graph the function. Adjust the graphing window to the following

Refers to the acceleration of the cannonball, in this case, caused by the gravitational force.
The linear term:

A bag contains 3 blue chips, 7 red chips, 4 yellow chips, and 5 green chips. A chip is randomly drawn from the bag. Find probability.
P (not red)
If a chip is randomly drawn from the bag, the probability it is not a red one is P(not red) = 12/19.
Probability of an event A is the number of event A divided by all possible outcomes. Mathematically,
P(A) = n(A)/n(S)
where:
n(A) = number of event A
n(S) = number of all possible outcomes or sample space.
Suppose there 3 possible outcomes, A, B, and C, then:
n(S) = n(A) + n(B) + n(C)
1 = P(A) + P(B) + P(C)
The probability the outcome is not event A is equal to the probability of (B or C), or in other words,
However,
P(B or C) = P(B) + P(C)
It means,
P(not A) = 1 - P(A)
In the given problem:
Number of chips:
Blue = 3
Red = 7
Yellow = 4
Green = 5
Total chips = 3 + 7 + 4 + 5 = 19
If a chip is randomly drawn, the probability it will be a red one is:
P(red) = 7/19
Hence
P(not red) = 1 - 7/19 = 12/19

suppose you are conducting a survey regarding illicit drug use among teenagers in the baltimore school district. you obtain a cluster sample of 12 schools within the district and sample all sophomore students in the randomly selected schools. the survey is administered by the teachers.
Response bias results from the possibility that not all sophomore students provided accurate information about their drug use, which will immediately result in the response bias because of false data.
What is response bias?
Response bias is a catch-all phrase for a variety of inclinations for participants to give misleading or inaccurate answers to queries. These biases are common in studies involving participant self-report, such as structured interviews or surveys. The validity of questionnaires or surveys can be significantly impacted by response biases.
The idea that human subjects do not passively respond to stimuli but rather actively integrate several sources of information to develop a response in a specific scenario is central to the concept that response bias can be induced or caused by a variety of causes. As a result, practically every element of an experimental condition has the ability to sway a respondent.
Explanation:
The remedy is to conduct a survey by licensed social workers since licensed social workers didn't explicitly ask sophomore students about drug use; instead, they interacted with the students as their friends before gathering the data.

which conversion factors are used to multiply to 18 cm/s to get meters per minute? select each correct answer.
The conversion factors are used to multiply to 18 cm/s to get meters per minute is 60s/1m.
What is conversion?The conversion procedure depends on the unique circumstances and the targeted goal. A rule, a contract, technical requirements, or other norms that have been made public may control this. The precision of the initial measurement must not be increased or decreased during some unit conversions from one system to another. Soft conversion is another name for this. It doesn't need altering the way the thing being measured is physically constructed.
A hard conversion or an adaptable conversion, on the other hand, could not be perfect equivalents. In the new system, it converts the measurement to practical and usable numbers and units. Sometimes it entails rearranging the item's parts significantly or changing its size.
18 cm/s means 18 cm in 1 second.
You must change 1 second into a minute and 18 cm into meters when converting 18 cm/s into meters per minute. 18 cm = 18/100 meters.
1 second = 1/60 minutes.
18/100 meters per 1/60 minutes
18/100÷1/60 = 18/100 ×60/1
= 18 ×(60/100) meters per minute
The factor is 60s/100cm, which is equivalent to 60s/1m

Prove by C/D formula that cos A + cos 2A + cos 5A = cos 2A (1 + 2 cos 3A)
We have proved the trigonometric expression cos A + cos 2 A + cos 5 A = cos 2 A (1 + 2 cos 3 A) by using C/D formula.
We are given the expression:
cos A + cos 2 A + cos 5 A = cos 2 A (1 + 2 cos 3 A)
We need to prove the expression.
We know that:
Cos C + Cos D = 2 cos ( C + D / 2) cos ( C - D / 2)
Using this identity, we get that:
= cos 5 A + cos A + cos 2 A = cos 2 A (1 + 2 cos 3 A)
= 2 cos ( 5A + A / 2) cos ( 5A - A / 2) + cos 2 A = cos 2 A (1 + 2 cos 3 A)
= 2 cos 3 A cos 2 A + cos 2 A = cos 2 A (1 + 2 cos 3 A)
= cos 2 A ( 2 cos 3A + 1) = cos 2 A (1 + 2 cos 3 A)
= cos 2 A (1 + 2 cos 3 A) = cos 2 A (1 + 2 cos 3 A)
LHS = RHS

Which equation is the inverse of y = 7x² - 10?
The inverse of y = 7x² - 10 is √(x+10)÷7
What does mathematics inverse mean?Inverse operations, such as addition and subtraction, multiplication and division, are pairs of mathematical operations where one operation reverses the effects of the other. The term "inverse" refers to the reciprocal of a number, i.e., x - 1 = 1 / x. One is the result when a number is multiplied by its reciprocal, or inverse.
based on the available facts;
y = 7x^2 - 10
Switch y and x.
x = 7y^2 - 10
Solve for y.
Add 10 to both sides.
x + 10 = 7y^2
Divide both sides by 7.
(x + 10)/7 = y^2
√ both sides.
√(x + 10)/7 = y
Replace y with f^-1(x)
f^-1(x) = √(x + 10)/7y = 7x^2 - 10
Switch y and x.
x = 7y^2 - 10
Solve for y.
Add 10 to both sides.
x + 10 = 7y^2
Divide both sides by 7.
(x + 10)/7 = y^2
√ both sides.
√(x + 10)/7 = y
Replace y with f^-1(x)
