To get onto the Honor Roll, Max has to get an average in math of at least a 90.
For five exams, he has an average of 88. What must he score on the next exam
to bring his average up to exactly 90?
Answers
Answer:
He needs to score 100 in his next test.
Step-by-step explanation:
The average of the exams is given by the sum of each exam score divided by the number of exams he took, therefore his prior average is:
\(\text{prior average} = \frac{\text{prior sum of grades}}{\text{prior number of tests}}\)
Since he took five exams and had an average of 88, then his prior sum of grades is:
\(\text{prior sum of grades} = 88*5 = 440\)
He needs to score "x" in his next test in order to have an 90 average, therefore if we add "x" to the sum of his grades and add 1 to the prior number of tests then equal that to 90, we can solve for "x". We have:
\(\text{desired average} = \frac{\text{prior sum of grades} + x}{\text{prior number of texts}+1}\\90 = \frac{440 +x}{6}\\440 + x = 90*6\\x = 540 - 440\\x = 100\\\)
He needs to score 100 in his next test.

Order the numbers from closest to zero to farthest from zero:
4.38, l4.5l, l-4.6l, -l4.9l
HELPPPPP
Answers
The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.
With that being said, here is the order of the numbers from smallest to largest:
4.38
4.5
4.6
4.9
Answer:
Here are the numbers ordered from closest to zero to farthest from zero:
4.38 (closest to zero)

Quadrilateral GHIJ is similar to quadrilateral KLMN. Find the measure of side KL. Round your answer to the nearest tenth if necessary.
Answers
Answer:
KL = 11.9 approximately
Step-by-step explanation:
It is stated that the two quadrilaterals are similar
if they are similar then their side lengths are proportional
So we can use that to find KL
JG/NK = GH/KL
(52.5)/17=37/KL cross multiply expressions
52.5*KL = 629 divide both sides by 52.5
KL = 11.9 approximately

Answer:
13 square units
Step-by-step explanation:
Look at image attached
Divide shape into two rectangles
Rectangle 1:
width: 2 units
length: 5 - 1 = 4 units
AREA: 2 x 4 = 8 sq. units
Rectangle 2:
width: 1 units

AREA: 1 x 5 = 5 sq. Units
Combine area of rectangles:
8 + 5 = 13 sq. Units
That is the area of the whole polygon.
Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Answers
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.

Choose the correct item from each drop-down menu to factor the trinomial 6y^2 + 19y + 15 by grouping.
Answers
The given trinomial can be factorized as (3y + 5) (2y + 3)
What are Trinomials?Trinomials are defined as the polynomials which consists of three terms.
Given trinomial is 6y² + 19y + 15.
We have to factorize the given trinomial.
This can be written as,
6y² + 19y + 15 = 6y² + 9y + 10y + 15
Now, take the common terms from the consecutive two terms.
6y² + 9y = 3y (2y + 3)
10y + 15 = 5 (2y + 3)
Substituting,
6y² + 19y + 15 = 6y² + 9y + 10y + 15
= 3y (2y + 3) + 5 (2y + 3)
= (2y + 3) (3y + 5)
= (3y + 5) (2y + 3)
Hence the trinomial is factorized as (3y + 5) (2y + 3).

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

The formula to find a percent increase is this: (original amount - new amount / original amount) * 100
If you fill in the formula, you get this:
(164,000 - 182,040 / 164,000) * 100
Solve:
(-18,040 / 164,000) * 100 ---> If the number being divided is negative, find the absolute value.
