Which of the following numbers are factors of 16 and 20?
Answer:
The set of factors of 20 is {1, 2, 4, 5, 10, 20} and the set of factors of 16 is {1, 2, 4, 8, 16}. {1, 2, 4, 5, 10, 20} ∩ {1, 2, 4, 8, 16} = {1, 2, 4} which has greatest value 4. So, GCF(20, 16) = 4.
Step-by-step explanation:
Answer:
The factors of 20 is 1, 2, 4, 5, 10, 20
The factors of 16 is 1, 2, 4, 8, 16

Find 3 numbers in G.P whose sum is 28 and whose product is 512
Answer:
4, 8 and 16
Step-by-step explanation:
a/r ×a×ar =512
a^3 =512
a = cube root of 512
a=8
8/r+8+8r=28
8r^2+8=20r
8r^2-20r+8=0
8r^2-16r-4r+8=0
8r(r-2)-4(r-2)=0
(8r-4)(r-2)=0
r=2
8r=4
so r=2 or r=1/2
so of r is 2
8/2=4
and 8×2=16

What angle relationship best describes angles AFC and DFB?
A) Adjacent angles
B) Complementary angles
C) Linear pairs
D) Vertical angles
Answer:
Vertical Angles
Step-by-step
I believe this is the case because since the angles intercept in order to form also it's the only answer that has to do with intercepting from what we can see from the diagram.
There are different types of relationships between angles including alternate, corresponding, vertical, adjacent, complementary and supplementary angles
The correct option for the relationship that best describes angles AFC and DFB is option D;
D) Vertical angles
The reason the chosen option is correct is as follows;
The given diagram shows line EF perpendicular to line AB and line CD crosses line AB at point F
Therefore, the angles ∠AFC and ∠DFB formed by lines AB and CD with their orientation in the order of their names are opposite to each other and other are known as vertical angles

Ayana and Victor have summer jobs selling newspaper subscriptions door-to-door, but their compensation plans are different. Ayana earns a base wage of $12 per hour, as well as $1 for every subscription that she sells. Victor gets $4 per subscription sold, in addition to a base wage of $6 per hour. If they each sell a certain number of subscriptions in an hour, they will end up earning the same amount. How many subscriptions would that be? How much would each one earn?
Answer:
2
$14
Step-by-step explanation:
Let x = number of subscriptions sold
Total income of Ayana per hour = $12 + $1x
Total income of Victor per hour = $6 + $4x
To find the number of subscriptions that would equate their incomes :
$12 + $1x = $6 + $4x
Collect like terms
$12 - $6 = $4x - $1x
$6 = $3x
Solve for x
x = $2
The subscription that would equate their income would be $2.
The income each would earn = $12 + $1(2) = $14
Write an equation of a line in slope-intercept form with the given slope and y-intercept.
slope: -4, y-intercept: -1
Answer:

The Tommy's class collect the amount of 14 dollar.
What is the solution for an equation?The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of that variable would give a true mathematical statement.
We need to find the solutions of the equation 2(x + $3.00)= $34.00 ;
Now solving for x;
2(x + $3.00)= $34.00
Open the bracket;
2x + 6 = 34
Combine the like terms;
2x = 34 - 6
2x = 28
x = 14
Therefore, the equation 2(x + $3.00)= $34.00 has only one solution which is 14.

Is it possible for an even degree polynomial to have no real zeros?
Answer:
All polynomial functions of positive, odd order have at least one zero (this follows from the fundamental theorem of algebra), while polynomial functions of positive, even order may not have a zero (for example x4+1 x 4 + 1 has no real zero, although it does have complex ones).

f(x) = - 3x + 4
f(x) = - *x+
f(V) = - 3y + 4
Answer:
b) y = f(x) = -3x+4
Step-by-step explanation:
Explanation
Given that the equation 9x+3y =12
Let 'x' be an independent variable and 'y' be the dependent variable then the function is of the form
y = f(x)
3 y = 12 - 9x
[tex]y = \frac{-9x+12}{3}[/tex]
y = -3x+4
The function represented by y = -3x+4
Suppose you invest $2200 at an annual interest rate of 5.3% compounded continuously. How much will you have in the account after 7 years?
Step-by-step explanation:
step 1. Let's call the amount of money A.
step 2. A = A¡e^(rt) (continuously compounding equation)
step 3. A = A¡e^(rt). A¡ = initial amount. r = rate, t = time.
step 4. A = 2200e^((.053)(7)

Marcos debe pintar 5/9 de la cubierta de un velero. Al acabar el día ha pintado 21/36 . ¿Ha conseguido cumplir su objetivo? ¿Ha pintado más? ¿Ha pintado menos?
Answer:
a) Have you managed to meet your goal?
Yes
b) Have you painted more? Have you painted less?
You have painted more.
Step-by-step explanation:
Marcos should paint 5/9 of the deck of a sailboat.
At the end of the day he painted 21/36.
Reducing this to the simplest form = 21/36
Dividing Numerator and Denominator by 3
= 7/12
Finding the difference between both fractions
= 7/12 - 5/9
The Lowest Common Denominator = 36
= 21 - 20/36
= 1/36
Therefore:
a) Have you managed to meet your goal?
Yes
b) Have you painted more? Have you painted less?
You have painted more.

i need help with number 1
Answer:
Step-by-step explanation:
Given
Points: (0,3) and (-4,-1)
Formula
x = 0 to find the y intercept
m = (y2 - y1)/(x2 - x1)
Solution
y2 = 3
y1 = - 1
x2 = 0
x1 = - 4
m = (3 - -1)/(0 - - 4)
m = 4/4
m = 1
You have y = mx + b so m = 1
the general equation becomes y = x + b
Use point (0,-4)
y = x + b
- 4 = 0 + b
b = - 4
y = x - 4
