Factor the expression 20k + 50

Answers

Answer is 10(2k+5)

-----------------------------------

Work Shown:

20k+50 = 10*2k + 10*5
20k+50 = 10(2k+5)

Note how we can distribute the 10 back in to check our work
10(2k+5) = 10(2k)+10(5) = 20k+50
so that confirms we have the right answer

Another thing to notice is that 10 is the largest factor that we can pull out of 20k and 50. The value 10 is the GCF (greatest common factor) of 20 and 50.

Suppose an investment of $10,000 doubles in value every 13 years. How much is the investment worth after 52 years? After 65 years?

A: $80,000; $100,000

B: $160,000; $320,000

C: $520,000; $650,000

Answers

Answer:


Step-by-step explanation:

The answer is actually B. $160,000; $320,000

The reason for this is because -

$10,000 is the constant, so let a= 10,000.

The investment doubles every 13 years, so let b=2.

Let x= the number of 13-year periods.


Final answer:

The value of a $10,000 investment doubling every 13 years will be $160,000 after 52 years and $320,000 after 65 years.

Explanation:

To calculate the value of an investment that doubles every 13 years, you can determine the number of times the investment will double over a given period. In this case, after 52 years, the investment will have doubled 4 times (since 52 divided by 13 is 4), and after 65 years, it will have doubled 5 times (since 65 divided by 13 is 5).

The formula for the future value of an investment that doubles is: Future Value = Present Value × (2^number of doublings).

After 52 years, the investment's worth would be calculated as follows:

$10,000 × (2^4) = $10,000 × 16 = $160,000

After 65 years, the investment's worth would be:

$10,000 × (2^5) = $10,000 × 32 = $320,000

Therefore, the correct answers are $160,000 after 52 years and $320,000 after 65 years, which corresponds to choice B.

What is the area of a rectangle with vertices at ​ (−6, 3) ​, ​ (−3, 6) ​ , (1, 2) , and (−2, −1) ? Enter your answer in the box. Do not round any side lengths.

Answers

[tex]A= L[/tex]·[tex]w[/tex]
I drew out each point and arrive at the conclusion that the longest side is equal to 4 and the shorter side to 3
so that means the answer is 12

Answer:

Area of the rectangle is 24

Step-by-step explanation:

Given the vertices of the rectangle to be (−6, 3) ​, ​ (−3, 6) ​ , (1, 2) , and (−2, −1)

Let the the vertices be at point ABCD respectively

so that A(-6, 3)  B(-3,6) C(1,2) D(-2 -1)

To find the area, we need to first find the length and height of the rectangle

We let AB to be the length of the rectangle and BC be the height of the triangle. so first, we will find the distance between the two points AB

A(-6, 3)  B(-3,6)

Using the distance formula

|AB| = √([tex]x_{2}[/tex]  -  [tex]x_{1}[/tex])²   +  ([tex]y_{2}[/tex] - [tex]y_{1}[/tex])²

       =√(-3+6)²    +   (6-3)²

     =√(3)²  +  (3)²

     = √(9+9)

     =√18

    =√(9 ×2)

     =√9  ×  √2

    =3√2

|AB| =  3√2

The length of the rectangle is  3√2

We will now proceed to find the height of the rectangle which is the distance between point the two point BC

B(-3,6) C(1,2)

Using the distance formula;

|BC |=  √([tex]x_{2}[/tex]  -  [tex]x_{1}[/tex])²   +  ([tex]y_{2}[/tex] - [tex]y_{1}[/tex])²

    =√(1+3)²  + (2-4)²

     =√4²  +  4²

     =  √(16 + 16)

    =√32

    =√(16 × 2)

     =√16  ×  √2

    =4√2

|BC|  = 4√2

Therefore, the height of the triangle is 4√2

Area of rectangle = l × h

                            = |AB| .  |BC|

                              = 3√2  ×  4√2

                                =12 (2)

                                =24

Therefore  area of the rectangle is 24

The volume of a rectangular prism can be computed using the formula V = lwh. What is the height of a prism that has a volume of 2376 cubic centimeters, a length of 18 centimeters, and a width of 11 centimeters?

A. 24 cm
B. 726 cm
C. 16 cm
D. 12 cm

Answers

I believe it is D because V= lwh. The length is 18 and the W= 18. the V is 2376. When solving this you replace it with the numbers so it would be 2376=18x11xh and then it would be 2376=198xh and it would equal to 2376=198x. When you get that answer you divide by 198 on both sides and get 12.

This isosceles triangle has two sides of equal length , a, that are longer than the length of the base , b. The perimeter of the triangle is 15.7 cm. The equation 2a + b = 15.7 models this information. If one of the longer sides is 6.3 cm, which equation can be used to find the length of the base ?

Answers

We are give the equation of the perimeter of the triangle as follows:
2a + b = 15.7 
where b represents the base.

Now, if we want to calculate the length of the base, all we have to do is isolate the b in one side of the equation as follows:
b = 15.7 - 2a

We know that a = 6.3 cm, therefore, the length of the base can be calculated as follows:
b = 15.7 - 2(6.3) = 3.1 cm

p - 1 - 5p = 3p - 8

Joan has a credit card that uses the previous balance method. The opening balance of one of her 30-day billing cycles was $6390, but that was her balance for only the first 3 days of the billing cycle, because she then paid off her entire balance and didn't make any new purchases. If her credit card's APR is 17%, which of these expressions could be used to calculate the amount Joan was charged in interest for the billing cycle?

Answers

Answer:

Step-by-step explanation:

(0.17/365 x30)(6390)

The expression that represents the amount Joan was charged in interest for the billing cycle is $26.84.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To calculate the amount Joan was charged in interest for the billing cycle using the previous balance method, we need to find the average daily balance for the billing cycle, which is calculated as the sum of the daily balances divided by the number of days in the billing cycle.

The daily balance is the balance at the end of each day, and it is calculated by adding new purchases and subtracting payments and credits from the previous day's balance.

In this case,

Joan had a balance of $6390 for the first 3 days of the billing cycle, so her average daily balance for the billing cycle can be calculated as:

((3 x 6390) + (27 x 0)) / 30

= 1917

This means that her average daily balance for the billing cycle was $1917.

To calculate the amount of interest Joan was charged for the billing cycle, we can use the following expression:

Interest = Average Daily Balance x Daily Interest Rate x Number of Days in Billing Cycle

The daily interest rate is calculated as the APR divided by 365 since there are 365 days in a year. In this case, the daily interest rate is:

0.17 / 365

= 0.000465753

So, the expression that can be used to calculate the amount of interest Joan was charged for the billing cycle is:

Interest = 1917 x 0.000465753 x 30

= $26.84 (rounded to the nearest cent)

Therefore,

The expression that represents the amount Joan was charged in interest for the billing cycle is $26.84.

Triangle MNP is the image of triangle JKL after a 120 degrees counterclockwise rotation about point Q. If the measure of angle L is 47 degrees and the measure of angle N is 57 degrees, determine the measure of angle M. Explain how you arrived at your answer.

Answers

Final answer:

The measure of angle M in triangle MNP is 76 degrees. This is determined by utilizing the sum of interior angles property of triangles and understanding the correspondence of angles in rotated or transformed figures.

Explanation:

The problem given is associated with the geometry of triangles. From the problem statement, we know that triangle MNP is the image of triangle JKL after 120 degrees counterclockwise rotation. This indicates that the angles of both triangles are the same. Hence, angle M will correspond to angle J of the original triangle.

However, since we are not given the measure of angle J, we need to calculate it using the property of triangles. In triangles, the sum of the interior angles amounts to 180 degrees. Therefore, the measure of angle J can be found by subtracting the measures of the other two angles (angle K and angle L) from 180 degrees.

Given the measure of angle L is 47 degrees and the measure of angle N (which corresponds to angle K in triangle JKL) is 57 degrees, we use the equation:
Angle J = 180 - (angle K + angle L) = 180 - (57+47) = 76 degrees.

Thus, the measure of angle M in triangle MNP, which is corresponding to angle J in triangle JKL, is 76 degrees.

The function H(t) = −16t2 + 48t + 12 shows the height H(t), in feet, of a cannon ball after t seconds. A second cannon ball moves in the air along a path represented by g(t) = 10 + 15.2t, where g(t) is the height, in feet, of the object from the ground at time t seconds.

Part A: Create a table using integers 0 through 3 for the 2 functions. Between what 2 seconds is the solution to H(t) = g(t) located? How do you know? (6 points)

Part B: Explain what the solution from Part A means in the context of the problem. (4 points)

Answers

Part A
t             0     1      2       3
H(t)      12   44    44     42
g(t)       10   25    40     56
Set H(t) = g(t) yields 16t^2 -32t -2 which shows its zeroes or points of intersections are at 0.6 and 2.1 seconds
Part B
H(t) = g(t) intersect at (x,y) points (0.6 secs, 9.1 feet)  and (2.1 secs, 42.1 feet)
H(t) is a parabola that opens downward which shows the cannonball arches upwards then falls downward.
g(t) is a straight linear line which slopes positive upwards and intersects G(t) in two places.

Answer with explanation:

We are given a function H(t) that represents the height of a cannon ball after t seconds as:

                  [tex]H(t)=-16t^2+48t+12[/tex]

and a second cannon ball is represented by the function g(t) as:

                       [tex]g(t)=10+15.2t[/tex]

PART A:

  t           0            1             2            3

H(t)        12          44          44           12

g(t)         15.2       25.2      40.4       55.6

Hence, between t= 2 seconds and t=3 seconds the ball will meet

     such that H(t)=g(t)

Since, we know that the Height H(t) decreases from 44 feet to 12 feet between t=2 to t=3 seconds.

and height g(t) increases from 40.4 feet to 55.6 feet between t=2 to t=3 seconds.

Hence, the two cannon balls will definitely meet between t=2 to t=3 seconds.

and the time at which they meet is calculated by solving:

[tex]H(t)=g(t)\\\\i.e.\\\\\\-16t^2+48t+12=10+15.2t\\\\\\i.e.\\\\\\16t^2-32.8t-2=0\\\\\\i.e.\\\\\\t=-0.059\ and\ t=2.109[/tex]

As t can't be negative.

Hence, we get:

t=2.109 seconds

PART B:

The solution from PART A means that the one of the ball first reach the highest point at 44 feet and then returns back to the initial position and hence follows a parabolic path while the second cannon ball reach a greater height with the increase in time and hence in this phenomena the two balls will definitely meet.

The volume of a rectangular prism can be computed using the formula v = lwh. what is the length of a prism that has a volume of 1344 cubic centimeters, a width of 8 centimeters, and a height of 12 centimeters?
a. 111 cm
b. 18 cm
c. 896 cm
d. 14 cm

Answers

We are given the formula:

V = l w h

 

and the following values:

l = ?

V = 1344 cm^3

w = 8 cm

h = 12 cm

 

SO rewriting the formula in terms of l:

l = V / w h

 

l = 1344 cm^3 / (8 cm * 12 cm)

l = 14 cm


Answer:

d

The answer would be 14
