Marilyn has a bag of coins. The bag contains 25 wheat pennines, 15 Canadian pennies, 5 steel pennies, and 5 Lincoln pennies. She picks a coin randomly from the bag. What is the probability that she picked a steel penny or a lincoln penny? A.) 10% B.) 20% C.) 50% D.) 30%
Answer:
B
Step-by-step explanation:
In probability, "AND" means to multiply and "OR" means to add.
Here they want probability of steel penny ( P(s) ) "OR" probability of lincoln penny ( P(l) ).
Let's find the individual probabilities and "ADD" them.
P(s) = 5/50 (since there are 5 steel pennies and there are 50 coins in total)
P(l) = 5/50 (since there are 5 lincoln pennies and there are 50 coins in total)
So probability of 5 steel penny and 5 lincoln penny = 5/50 + 5/50 = 10/50 = 1/5
1/5 is equal to 20%, correct answer is B

identify an equation in point-slope intercept form for the line perpendicular to y=3x+5 that passes through (4,-1)
Answer:
y + 1 = - [tex]\frac{1}{3}[/tex](x - 4)
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 5 is in this form
with slope m = 3
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{3}[/tex]
The equation of a line in point slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here (a, b) = (4, - 1), thus
y - (- 1) = - [tex]\frac{1}{3}[/tex](x - 4), that is
y + 1 = - [tex]\frac{1}{3}[/tex](x - 4) ← in point- slope form
Rhea had a score of a 70 on her first quiz and a score of a 77 on her second quiz. What is the percent increase from her first quiz score to her second quiz score?
The answer is:
The percent increase from her first quiz score to her second quiz score is 10%.
Why?To know what is the percent increase from her first quiz to her second quiz, first we need to calculate the increase points, then, represent it in porcentage value.
Then, calculating her increas in points, we have:
[tex]Increase=SecondQuizScore-FirstQuizScore\\Increase=77points-70points=7points\\Increas=7points[/tex]
Now, calculating the percent increase, we have:
[tex]Increase(Percentage)=\frac{Increase(points)}{FirstScore}*100\\\\Increase(Percentage)=\frac{7}{70}*100\\\\Increase(Percentage)=0.10*100=10[/tex]
Hence, the percent increase from her first quiz score to her second quiz score is 10%.
Have a nice day!

Angelo runs 7 miles per week and increases his distance by 1 mile each week. Marc runs 4 miles per week and increases his distance by 2 miles each week. In how many weeks will Angelo and Marc be running the same distance? What will that distance be?
Answer:
Step-by-step explanation:
You have to set each runner's plan equal to each other because they are equal in the end. You start with 7 miles for Angelo and 4 miles for Marc.
x is a variable that is multiplied by the number of weeks it takes for both runners' distances to be equal. So multiply x by the miles increased every week.
Marc = Angelo
2x + 4 = x + 7
x = 3
In 3 weeks each runner will run 10 miles for the week.
To find when Angelo and Marc will be running the same distance and what that distance will be, set up and solve equations.
Explanation:To find out in how many weeks Angelo and Marc will be running the same distance, we can set up an equation. Let's assume the number of weeks is x. Angelo's distance can be represented by the equation 7 + 1x, and Marc's distance can be represented by the equation 4 + 2x. To find when their distances are equal, we can set the two equations equal to each other and solve for x.
Setting the equations equal: 7 + 1x = 4 + 2x
Simplifying the equation: x = 3
Therefore, Angelo and Marc will be running the same distance in 3 weeks. To find the distance, we can substitute the value of x back into either of the original equations. Let's use Angelo's equation: 7 + 1(3) = 10
So, Angelo and Marc will be running 10 miles in the same distance.

Step-by-step explanation:
Hello
For X = 11 you only have to replaced the value into the expression, so:
3(11) + 4(11-8) - 14
33 + 4(3) - 14
33 + 12 - 14
31
Best regards
Hello there!
Plug 11 into the equation, by replacing x with it and simplify.
3x+ 4(x-8) - 14
3(11) + 4(11-8) - 14 -- Remember PEMDAS, start by subtracting 11 - 8.
3(11) + 4(3) - 14 -- Next, multiply 3 by 11.
33 + 4(3) - 14 -- Now, multiply 4 by 3.
33 + 12 - 14 -- Now, add 33 to 12.
45 - 14 -- Now, take 14 away from 45.
31 -- This is your final answer.

Step-by-step explanation:
Hobby Shop is selling model cars and model trucks for 50% off this week. At the sale price, you can buy one car and one truck for $13.00. Also at the sale price, you can buy 4 trucks and 2 cars for $42.00. What is the sale price and the original price of the model car and the model truck?
Answer:
The truck original price is $16.00 and the car price is $5.00.
The truck sale price is $8.00 and the car price is $10.00.
Step-by-step explanation:
We need to find the original price of the truck (T) and car (C)
Sale price of the truck is 50% so that means it is half the original price.
Now let's see the equations we can come up with there:
At sale price:
[tex]T + C = \$13.00\\\\4T + 2C = \$42.00[/tex]
We can solve this through substitution.
Using the first equation, we can come up with an equation for one of the missing variables.
[tex]T + C =\$13.00\\\\C = \$13.00 - T[/tex]
We can use this equation on the second one, to solve for one variable. [tex]4T + 2C = \$42.00\\\\4T + 2(\$13.00-T) = \$42.00\\\\4T + \$26.00 - 2T = \$42.00\\\\4T - 2T = \$42.00 - \$26.00\\\\2T = \$16.00\\\\\dfrac{2T}{2}=\dfrac{\$16.00}{2}\\\\T = \$8.00[/tex]
The sale price of the model truck is $8.00.
Now can use this on the first equation again.
[tex]T + C = \$13.00\\\\\$8.00 + C = \$13.00\\\\C = \$13.00 - \$8.00\\\\C = \$5.00[/tex]
The sale price of the model car is $5.00.
Because it is 50% off on both models, the original price is twice the sale price. So we can solve it by multiplying the sale prices by 2.
Original price of model truck: $8.00 x 2 = $16.00
Original price of model car: $5.00 x 2 = $10.00
Answer:
The truck's original is $16. The sale price is $8. The car's original is $10. It's sale is $5.

What is the zero of the following function?
Answer:
D
Step-by-step explanation:
The zero of the function is the point on the x- axis where the graph crosses
That is x = - 5
Answer: OPTION D
Step-by-step explanation:
The zero of the function is the intersection of the function with the x-axis.
A function intersects the x-axis when the value of y is zero ([tex]y=0[/tex])
Then, you can observe in the graph attached that the function intersects the x-axis at the point (-5,0), where the x-coordinate is -5 and the y-coordinate is 0:
[tex]x=-5\\y=0[/tex]
Therefore, you can identify that the zero of the function shown in the figure is:
[tex]x=-5[/tex]
This matches with the option D.

Only the last two options are true.
The first one is false, because 4.5 is the value of the maximum of f(x), not the point where it is reached.
The second one is false, because g(x) has a maximum of 9, so it is a downward-facing parabola (just like f(x)), so it doesn't have a minimum.
The third one is true, because the maximum value of f(x) is 4.5, and the maximum value of g(x) is 9, which is twice the maximum of f(x)
The last one is false (see point 2).
Answer:
The third and last one.
Step-by-step explanation:
First, by looking at the graph you can tell that the parabola peaks where x = 0.5, not 4.5, so this one is incorrect.
The second one is incorrect, because the value of the g(x) at 0 is 9, but he function is less at other values such as when x is -3 and the g(x) is 0.
The maximum value of the g(x) is 9. We can tell this because points with an equal difference of x values away from x = 0 (where g(x) = 9), also have the same y values. Because 9 is twice of 4.5, and 4.5 is the maximum value of the f(x), the third one is correct.
Lastly, The last one is true, because quadratic functions only have a minimum or a maximum value and we already know that both of these functions have a maximum value.

Find the values for c and d that would make the following equation true. (cy^2)(4y^d)=-20y^3
Answer:
c = -5 and d = 1
Step-by-step explanation:
First, multiply out (cy^2)(4y^d). We get: 4cy^(2+d).
We equate this result to the right side of the equation: - 20y^3.
Then, equating the exponents and solving for d, we get: 2 + d = 3, or d = 1.
Equating the coefficients, we get 4c = -20, or c = -5.

how do you rewrite 1/27 as an expression with a negative exponent
Answer:
3^-3
Step-by-step explanation:
27 = 3^3
so
1/ 27= 1 / 3^3 = 3^-3
To write the fraction \( \frac{1}{27} \) as an expression with a negative exponent, you can use the property of exponents that states \( a^{-n} = \frac{1}{a^n} \), where \( a \) is any non-zero real number and \( n \) is a positive integer.
Applying this property to \( \frac{1}{27} \), we can see that the fraction is the reciprocal of \( 27 \) raised to the first power. Thus, we rewrite the expression \( \frac{1}{27} \) by flipping the position of \( 27 \) to the numerator and making the exponent negative:
\( \frac{1}{27} = 27^{-1} \)
So, \( 27^{-1} \) is the same as \( \frac{1}{27} \). When you calculate \( 27^{-1} \), you get the value of approximately \( 0.037037037037037035 \), which represents the decimal equivalent of the fraction \( \frac{1}{27} \).
Comstock nut company has 500 pounds of peanuts to package if each package contains one and one four pounds how many packages are needed?
Answer:
2000
Step-by-step explanation:
500/0.25. :) hope this helped
Comstock Nut Company can make 400 packages of peanuts by dividing the total weight of peanuts (500 pounds) by the weight of each package (1.25 pounds). Ounces or grams would be suitable to measure a handful of peanuts.
Explanation:To calculate how many packages Comstock Nut Company can make, we simply divide the total weight of the peanuts by the weight of each package. They have 500 pounds of peanuts and each package weighs 1 and 1/4 pounds (which is the same as 1.25 pounds).
Number of packages = Total weight of peanuts ÷ Weight per package
Number of packages = 500 pounds ÷ 1.25 pounds/package
When you divide 500 by 1.25, you get 400. Therefore, Comstock Nut Company can make 400 packages of peanuts.
When it comes to choosing the best unit of measurement, for a handful of peanuts, we would typically use ounces or grams since they are small quantities that don't weigh much, similar to how Jeffrey should use ounces to label packages of steak when most are less than a pound.
