Answer:
Jenny James would need to have a score of 97 out of 100 points in order to have an average of 90.
Step-by-step explanation:
Given that:
Scores of four tests
78, 89, 90 and 96
Let,
x be the score on fifth test.
Average is the sum of quantities divided by total number of quantities.
Average = 90
Average = [tex]\frac{Sum\ of\ scores}{No.\ of scores}[/tex]
Putting the values in the formula;
[tex]90=\frac{78+89+90+96+x}{5}\\90=\frac{353+x}{5}\\90*5=353+x\\450=353+x\\450-353=x\\x=97[/tex]
Hence,
Jenny James would need to have a score of 97 out of 100 points in order to have an average of 90.

John is about to take a 75-item multiple-choice test. If he finishes an average
of 5 items every 3 minutes, how long will it take him to complete the test?
1. 15 minutes
2. 25 minutes
3. 45 minutes
4. 60 minutes
Answer:
It will take John 45 minutes (option 3 or C) to finish the test.
Step-by-step explanation:
We know that John is about to take a 75-item quiz. If he finishes 5 items every 3 minutes, then we can divide 75 by 5.
75 ÷ 5 = 15
Now, let's multiply 15 minutes by 3 minutes to get the total amount of minutes.
15 x 3 = 45 minutes
Therefore, it will take John C. 45 minutes to finish the test.

Which point is located at (4, 1)?
A
B
C
D
Answer:
A is located at (4,1)
Step-by-step explanation:
The first number will always be on the x-axis and the second will always be on the y-axis. For example: (x,y) so A is (4,1) , B is (-4,1), C is (1,4) and D is (-1,4).
Hope this helps! ;)
Final Answer: Point A
Steps/Reasons/Explanation:
Question: Which point is located at [tex](4, 1)[/tex]?
The x-axis would be 4 and the y-axis would be 1. The x-axis is horizontal and the y-axis is vertical.
For the x-axis, it tells you the markings of the numbers, so moving to the right would be positive and left would be negative.
For [tex](4, 1)[/tex] we would go four to the right and one up. Point A is located there.

there are two angels (S,Q). They equal 48.5
so 48.5x2= 97
all angels together (QRSP) equals 360
you can take the 97 and subtract it from the 360 =263
divide 263 to get the angels for P and R
S= 48.5

PLEASE HELP MEEE!!!!
Answer:
The correct option is;
B, C, and D
Step-by-step explanation:
The labelled letters on the number line are;
A = 2 units to the left of the point 0 = - 2 units
B = 1 units to the left of the point 0 = - 1 unit
C = Located at the point 0
D = 1 units to the right of the point 0 = +1 unit
Therefore, the letters that have their opposites labelled are;
Given that we have;
The opposite of B = -1 is +1 = D
The opposite of D = +1 is -1 = B
The opposite of C = 0 is 0 = C
The letters which have their opposites labelled are B, C and D
Linda had a previous balance of $1,000 and made an on-time credit card payment of $800. She has a credit line of x dollars and made purchases totaling y dollars. Write an algebraic expression that represents her current available credit.
Answer:
[tex]x-200+y[/tex]
Step-by-step explanation:
We can determine the algebraic expression that represents her current available credit by first finding her new balance using the formula:
Previous balance - Payments + Total Purchases = New balance
where, previous balance = $1000; payments = $800; total Purchases = y
New balance = [tex]1000-800+y[/tex]
Next, to find her Credit balance or current available; we use the formula; Credit line - New balance
where credit balance = x; new balance = [tex]1000-800+y[/tex]
Current available credit = [tex]x-200+y[/tex]

Answer:
I'm pretty sure it's A because its showing that the line starts from 1 and goes up if that makes sense.
Answer:
B
Step-by-step explanation:
x < 1 means that x is lesser than 1. A shows x is more than 1 so it is wrong. C shows x is more than -1 which is not entirely true since x could be more than -1, but not less than 1. However, the line in C stretches all the way to 8 which is more than 1 so it is wrong. D shows that x is lesser than -1, but x could have been 0 or -1, so it is not true either.

Line A Is Parallel To Line B. If The Measure Of Z7 Is 114”, What Is The Measure Of 3
Answer:
114°
Step-by-step explanation:
because they are parallel they have the same measure
The measure of angle 3 is equal to 114° when angle 7 is 114° by the corresponding angle property.
What are correspondence angles?The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
According to the definition of corresponding angles, when two parallel lines cross the third one, the angles that are in the same relative position at each intersection are referred to as being corresponding angles to one another.
In the image, it is given that angle 7 is 114 degrees. As in the image, the two parallel lines a and b are cut by the transversal line. The given angle 7 is 114°.
From the correspondence angle property, the two angles on the same side of the transversal line will be equal to each other. The angle 3 will be calculated as:-
∠7 = ∠3
114 = ∠3
Therefore, angle 3 will be 114°.

What are the next two terms in the sequence 22, 15, 8, __, __? 1, -7 2, -4 2, -6 1, -6
Step-by-step explanation:
The sequence is an AP with common difference -7.
Therefore the next 2 terms are 1 and -6.
The next two terms are ( 1, - 6 ) so the correct answer is option D.
What is arithmetic progression?
The sequence in which every next number is the addition of the constant quantity in the series is termed the arithmetic progression.
The next two numbers will be calculated as:-
22, 15, 8, __, __
Common difference = 15 - 22 = -7
Add this common difference in 8 to find the next term.
Next term = 8 - 7 = 1
Again add -7 to 1 to find the next term.
Next term = 1 - 7 = -6
Therefore the next two terms are ( 1, - 6 ) so the correct answer is option D.

Which ordered pairs are soultions to the inequality y-2x<-3
Answer:
(-3, 3/2)
Step-by-step explanation:
Given the inequality function y-2x<-3, to get the solution, we will need to find the x and y-intercept of the inequality function
y-intercept occurs at x = 0
Substitute x = 0 into the expression
y - 2(0) < -3
y < -3
Find the x-intercept by substituting y = 0 into the expression
0 - 2x < -3
-2x < -3
x > 3/2
Hence the ordered pair is (x, y) = (-3, 3/2)
