Answer:
90%
Step-by-step explanation:
So Sally gets 18/20 of the questions correct then you need to make the denominator of the fraction to 100 which makes a percent. So you multiply both the numerator and denominator by 5:
90/100
which is equal to 90%
Hope this helps!

04.03 MC) The price of blackberries at a farm is $1.56 per pound. Which equation can be used to determine c, the total price of n pounds of blackberries? (5 points) Select one:
A. c = 1.56n
B. c= 1.56 over n
C. c = 1.56 + n
D. c = 1.56 − n
Answer:
A. c = 1.56n
Step-by-step explanation:
In this situation n equals the independent variable. The independent variable means that no matter what the rest of the equation is this will be equal to a certain number.
Now, the correct answer will be A. This is because you will want to multiply 1.56 per pound. When you have a situation like this you know that the amount of money will be added to itself over and over depending on the independent variable. In other words, it will be multiplied by the independent variable.
Lets use this formula:
[tex]x * y = z[/tex]
x = Price of blackberries
y = Number of pounds
z = Total price of blackberries per y pounds.
Now change that to have our variables:
[tex]1.56* n = c[/tex]
or in other words:
[tex]c = 1.56n[/tex]
In the table below I will provide an example of what c will look like depending on n.
[tex]\begin{array}{|c|c|} \cline{1-2} \textbf{n} & \textbf{c} \\ \cline{1-2} 0 & 0 \\ \cline{1-2} 1 & 1.56 \\ \cline{1-2} 2 & 2.13 \\ \cline{1-2} 3 & 4.68 \\ \cline{1-2} 4 & 6.24 \\ \cline{1-2} 5 & 7.80 \\ \cline{1-2} \end{array}[/tex]
As you can see, n will be multiplied by 1.56 to find c. Thus proving our answer is A. [tex]c = 1.56n[/tex]
~Hope this helped!
Answer:
The equation that represents the relationship between the total price and the pounds of blackberries purchased is c = 1.56n.
Step-by-step explanation:
We are given that the price of the blackberries is $1.56 per pound. Therefore, for each pound, the price increases by $1.56.
This is going to be a linear relationship, so our equation is going to be in the form of [tex]y = mx + b[/tex] (this is the parent function for a linear function).
For example, say an individual purchases 3 pounds of blackberries.
Therefore, the initial purchase is going to start at $0 (nothing has been paid for if no blackberries are purchased).
Then, we will have to add the price to itself three times to get our total payment: [tex]1.56+1.56+1.56 = \$4.68[/tex]
After we do this, we can realize that when we add the same value a certain number of times, we can just multiply that value by the amount of times we've added it.
If we purchase the 3 pounds of blackberries, we would multiply $1.56 by 3 to get the total price of the blackberries. So, if we label our pounds of blackberries with a variable, we can see this relationship.
Now, our three pounds of blackberries can be labeled as n. So, we are multiplying $1.56 by n.
[tex]\$1.56 \times n[/tex]
This would give us our total cost, c.
Therefore, our multiplication of $1.56 and n is equal to c, so we can set those equal to each other.
[tex]c=\$1.56\times n[/tex]
Finally, in math, there is a statement that says that when you multiply a constant by a variable, you can drop the multiplication symbol and simply combine the two (for example, [tex]3 \times n[/tex] becomes [tex]3n[/tex]). With this, our equation now becomes:
[tex]c= \$1.56n[/tex]
Therefore, our answer is Choice A.

Find the domain:
[tex]y=\frac{x+3}{|x-1|-4}[/tex]
Answer:
the function domain:
x<5 or x>5
Step-by-step explanation:
For this type of function, the domain is all real numbers. A function with a fraction with a variable in the denominator. To find the domain of this type of function, set the bottom equal to zero and exclude the x value you find when you solve the equation. A function with a variable inside a radical sign.
In the diagram below, line AB is parallel to line CD. The measure of
∠∠ABC is 28° and the measure of ∠∠EDC is 42°. Find the measure of∠∠CED. Explain why you are correct by presenting an informal argument that uses the angle sum of a triangle.
what is the measure of ∠∠CED is ? And Explain why ?
Answer:
ced is 110 degrees
Step-by-step explanation:
because ECD is 28 degrees and 28+42=70 and a triange always = 180 degrees so it would have to be 110
The measure of ∠CED is 110 degrees by angle sum property of the triangle.
We are given that line AB is parallel to line CD.
The measure of ∠ABC is 28° and the measure of ∠EDC is 42°
What are exterior angles?An exterior angle is a measure of rotation between one extended side(we extend it virtually) of the polygon with its adjacent side which is not extended.
We know that line AB is parallel to line CD.
So according to alternate interior angles measure of ∠ABC is 28° will be equal to BCD.
Thus, Angle BCD= 28 degrees
Hence, in a triangle CED
∠CED + ∠EDC + BCD = 180
∠CED + 28 + 42 = 180
∠CED = 180 - 70
∠CED = 110 degrees
Therefore, the measure of ∠CED is 110 degrees by angle sum property of the triangle.
