Ebony earned scores of 71 , 70, 87, 97 , and 82 on five math tests. Determine her
score on the sixth test if her average for the six tests was 83? Enter your answer as a
whole number

Answers

Answer 1

The answer is 91

Step-by-step explanation:

Average Marks = (Total Marks) ÷ Total Tests

83 = (71 + 70 + 87 + 97 + 82 + x) ÷ 6

83 × 6 = 407 + x

498 = 407 + x

x = 498 - 407

x = 91

Write a conjecture that describes the pattern in the sequence. Then use your conjecture to find the next item in the sequence. 0,2,4,6,8

Answers

The conjecture that describes the pattern in the sequence is current term is 2 added to the previous term and the next term is 10

How to write a conjecture that describes the pattern in the sequence?

The sequence is given as:

0, 2, 4, 6, 8

In the above sequence, we can see that each current term is 2 added to the previous term

i.e.

Tn = 2 + Tn-1

Using the above conjecture, we have

Next term = 8 + 2

Evaluate

Next term = 10

Hence, the conjecture that describes the pattern in the sequence is current term is 2 added to the previous term and the next term is 10

A person is $1000 on the credit card that charges an interest rate of 2% per month complete the table showing the car to balance each month if you do not make any payments

Answers

Answer:

Month        Total Bill

2                  1,020

3                  1,040.40

6                  1,104.08

7                  1,126.16

8                  1,148.69

Step-by-step explanation:

Use the formula for compound interest

[tex]A = P(1+r)^t[/tex]

where A is the balance, P is the principal (credit card balance), r is the effective rate and t is the number of time periods

Here r = 2% computed monthly which is 2/100 = 0.02 in decimal and t = 1, 2,3,4,5,6,7,8 months

So 1 + r = 1+0.02 = 1.02

We can compute the monthly balance for each subsequent month by multiplying the previous month's balance by 1.02

All figures rounded to the nearest cent

Answer

Month        Total Bill

1                  1000

2                  1,000 x 1.02 = 1,020

3                 1,020 x 1.02 = 1,040.40

4                 1,040.40  x 1.02 = 1,061.21

5                  1,061.21  x 1.02 = 1,082.43

6                  1,082.43 x 1.02 = 1,104.08

7                  1,104.08 x  1.02 = 1,126.16

8                   1,126.16 x 1.02 = 1,148.69

Answer:

Fibonacci sequence is one of the most known formulas in number theory. In the Fibonacci sequence, each number in the series is calculated by adding the two numbers before it. Generally, the first two terms of the Fibonacci series are 0 and 1.

Any Fibonacci number can be calculated by using this formula,

xn =  (φn − (1−φ)n)/√5

xn denotes Fibonacci number to be calculated

φ is Golden ratio = 1.618034

the condition given in the question and applying the Fibonacci formula:

By the use of the Fibonacci number formula, we can calculate the rest of the Fibonacci numbers like 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89.

Therefore, the 8th term will be 21.

ALGEBRA Michella Hong noticed that her gross pay per period increased by $2,800 when her employer changed from a bi-weekly pay plan to a monthly pay plan. What is Michelle's annual salary

Answers

Answer:

Her annual salary is $62,400

Step-by-step explanation:

Michelle Hong noticed that her gross pay per period increased by 2,800 when her employer changed from a bi weekly pay plan to a monthly pay plan.

Bi weekly is a check every 2 weeks, so she would get 26 checks per year.

Monthly would be 12 checks per year.

When she gets paid monthly her pay increased by $2,800 each check.

Let x be one bi-weekly paycheck.

The equation we get is:

12(x+2800) = 26x

Multiply the bracket by 12:

12x +33600 = 26x

Subtract 12x from both sides

33600 = 14x

Divide both sides by 14:

x = 33600/14

x = 2400

Her pay increased by 2800 each period:

2400 + 2800 = 5200 per check.

5200 x 12 months = 62400

Her annual salary is $62,400

As per the question statement, We are given a function [tex]f(x) = -4x + 6[/tex]   and we are supposed to find the zero(s) of the function.

We know that zero of a function is the value of the function at which the value of function becomes absolute zero.

For that we have to equate the function to zero first.

f(x) indicates the function with variable in "x"

For zero(s), of f(x)

Let f(x) = 0

how to multiply a fraction(s)?

Answers

Fractions Context: How do they work?  -

- In every fraction, there's a top number and a bottom number, separated by a short horizontal line.

- In a proper fraction, the smaller number — called the numerator — will always be on top, while the larger number — the denominator — will be on the bottom.

(NOTE: The larger number is not always on the bottom, when it's on the top it is considered an improper fraction!)

- The numerator tells us how many units we have of a whole and the denominator tells us how many units make up the whole. So, in the fraction 1/2, 1 is the numerator and 2 is the denominator — there are two units in the whole, but this fraction tells us that we only have one of these units.

Write an equation in slope-intercept form for the perpendicular bisector of the segment with the given endpoints. Justify your answer. (Lesson 5-1)
D(-2,-4) and E(2,1)

Answers

The equation of the perpendicular bisector of the segment with the endpoints located at D(-2  ,-4) and E(2 , 1) is y = -4/5x - 3/2.

A perpendicular bisector of a segment is a line that divides the segment into two equal parts forming right angles at the point of intersection.

To get the perpendicular bisector of a segment, get the point of intersection of the two lines which is the midpoint of the segment.

midpoint (x , y) = [(x1 + x2)/2 , (y1 + y2)/2]

midpoint (x , y) = [(-2 + 2)/2 , (-4 + 1)/2]

midpoint (x , y) = (0 , -3/2)

Get the slope of the perpendicular bisector of a segment by taking the negative reciprocal of the slope of the segment.

slope of segment = (y2 - y1)/(x2 - x1)

slope of segment = (1 - -4)/(2 - -2)

slope of segment = 5/4

slope of the perpendicular bisector = -4/5

Solving for the y-intercept, b, plug in the point (0 , -3/2) and the slope -4/5 to the slope-intercept form of the equation, y = mx + b.

y = mx + b

-3/2 = -4/5(0) + b

b = -3/2

Setting up the equation in slope-intercept form, where m = -4/5 and b = -3/2.

y = mx + b

y = -4/5x - 3/2

Find QM

I am being tested on this tomorrow but this doesn’t make sense to me

Answers

Answer is QM = 18

You can find the length of QM by using Pythagorean theorem. See the attachment.

It is a quadrilateral with 4 equal congruent sides.

If SP = 30, so do the other 3 sides indicated by the tick marks on all 4 sides.

We will call side RQ = the hypotenuse
or side “c” = 30
We know RM is leg “b” = 24
Side “a” is our unknown QM

Our formula is
a^2 + b^2 = c^2

a^2 + 24^2 = 30^2

a^2 + 576 = 900

a^2 = 900 - 576

a^2 = 324

Take square root of both sides to solve a

a = 18

QM = 18
