Small baskets of tomatoes are sold at a vegetable stand for $3 per basket. Large baskets
of tomatoes are sold at the stand for $5 per basket. Only whole numbers of baskets may be
purchased.
Another customer claims that he can purchase a total of 10 baskets of tomatoes
and pay $45.
B. Use a system of equations that describes this other customer's purchase to
explain why the claim is incorrect.
hello lol srry I don't know what to do
The customer's claim is incorrect because the value of the number of baskets are in decimal.
What is a system of equation?A system of equations is a set or collection of equations that you deal with all together at once. For a system to have a unique solution, the number of equations must equal the number of unknowns.
For the given situation,
Let the number of small baskets be x
and the number of large baskets be y
Price of small basket = $3 per basket
Price of large basket = $5 per basket
Number of baskets purchased by customer = $45
The system of equations for the above statements are
[tex]x+y=10[/tex] ------ (1)
[tex]3x+5y=45[/tex] ------ (2)
From 1, [tex]x=10-y[/tex]
Now, substitute x in equation 2,
⇒ [tex]3(10-y)+5y=45[/tex]
⇒ [tex]30-3y+5y=45[/tex]
⇒ [tex]2y=45-30[/tex]
⇒ [tex]2y=15[/tex]
⇒ [tex]y=\frac{15}{2}[/tex]
⇒ [tex]y=7.5[/tex]
Substitute the value of y in equation 1, we get
⇒ [tex]x=10-7.5[/tex]
⇒ [tex]x=2.5[/tex]
Only whole numbers of baskets may be purchased. But the value of x and y are in decimals.
Hence we can conclude that the customer's claim is incorrect because the value of the number of baskets are in decimal.

PLEASE HELP ME DUE IN A HR
Answer:
x = 34.85
Step-by-step explanation:
Apply trigonometric ratio formula to find x
Reference angle = x
Side opposite to x = 4
Hypotenuse = 7
Therefore,
Sin x = opp/hyp = 4/7
x = sin-¹(4/7)
x = 34.85° (nearest hundredth)

Answer:
(sin x)^2*(sec x) is positive in QII
Step-by-step explanation:
(sin x)^2 is always 0 or positive. Here x lies in QII.
sec x is positive when the adjacent side is positive and negative when the adjacent side is negative. In QII the adjacent side is positive.
In summary, (sin x)^2*(sec x) is positive in QII

PLEASE HELP!! Write an equation of g(x) that represents an exponential base “e” parent function with the following transformations:
Reflect over y-axis, shift right 7, vertical stretch by 12
Answer:
[tex]g(x) = 12 {e}^{ - x - 7} [/tex]
Step-by-step explanation:
The parent function is
[tex]g(x) = e {}^{x} [/tex]
First it is asked to reflect over the y axis so using the rule
[tex]g(x) = g( - x)[/tex]
Our function looks like
[tex]g(x) = e {}^{ - x} [/tex]
Then we are asked to shift the equation to the right 7. When shifting to the right or move the x axis, instead of adding 7 we would want to subtract 7 since the x axis is the independent variable and we must respect the y axis which is the dependent so using the rule
[tex]g(x) = g(x - h)[/tex]
When subtracting a 7 it looks like now
where h is the number we move . Now we are asked to apply a vertical stretch of 12. Since vertical stretch refers to the y axis, we are just going to multiply the function by 12 using the rule
[tex]g(x) = a \times g(x)[/tex]
where a is the vertical stretch. So now it would look like
[tex]g(x) = 12 {e}^{ - x - 7} [/tex]

62.5% of what number is 30?
Answer:
48
Step-by-step explanation:
Answer:
62.5% of 48 is 30
Step-by-step explanation:
Move the percentages place value two times... and it'll become .625 now multiply that to 48 and you get 30 but if you wanted to start out with 62.5% and 30 all you got to do is move the place value two time again and divide .625 to 30 and you get 48 and that is why the answer if 48

The scatter plot shows the relationship between elevation and temperature on a certain mountain peak in North America. Which statements are correct?
A. The data shows one potential outlier
B. The data shows a linear association
C. The data shows a clustering pattern
D. The data shows a negative association
E. As elevation increases, temperature decreases
The scatter plot shows the data having a clustering pattern, and as elevation increases, temperature decreases.
What is a scatter plot ?"Scatter plots are the graphs that present the relationship between two variables in a data-set. It represents data points on a two-dimensional plane or on a Cartesian system. The independent variable or attribute is plotted on the X-axis, while the dependent variable is plotted on the Y-axis. These plots are often called scatter graphs or scatter diagrams."
"A scatter plot is also called a scatter chart, scattergram, or scatter plot, XY graph. The scatter diagram graphs numerical data pairs, with one variable on each axis, show their relationship"
Since, the graph is a scatter plot so the data shows a clustering pattern.
and from the plot we can conclude that as elevation increases, temperature decreases.
Hence, C, E are the correct option.

The police use a speed gun to monitor one part of a highway. During one hour, 4 out of 25 cars were traveling above the speed limit. What percent of cars were traveling above the speed limit.
Answer: 16%
Step-by-step explanation: Because if you look at that denominator then you can see that its 25 so if you multiplied that by 4 then you'll get 100 which is 100% so whatever you do to the denominator you have to do to the numerator so 4x4 is 16 so thats 16% and there you go.

In order to factor an integer, we need to repeatedly divide it by the ascending sequence of primes (2, 3, 5...).
The number of times that each prime divides the original integer becomes its exponent in the final result.
