Answer:
After 5 weeks.
Step-by-step explanation:
Westley starts with $85 and saves $5 per week. So:
[tex]y=85+5x[/tex]
Buttercup starts with $10 and saves $20 per week. So:
[tex]y=10+20x[/tex]
When they have the same amount of money, the two equations will be equal to each other. Therefore:
[tex]85+5x=10+20x[/tex]
Solve for x. Subtract 10 from both sides:
[tex]75+5x=20x[/tex]
Subtract 5x from both sides:
[tex]75=15x[/tex]
Divide both sides by 15:
[tex]x=5[/tex]
Westley and Buttercup will have the same amount of money after 5 weeks.

Answer:
Linear pair
Step-by-step explanation:
<1 and <2 lie on a straight line.
Angles that lie on a straight line are considered as linear pair angles.
Linear pair angles sum up to 180°, which is the measure of a straight line angle.

Answer:
(a)(b)=0.45
a/b=0.8
Step-by-step explanation:
a=0.6
b=0.75
(a)(b)=(0.6)(0.75)=0.45
a/b=0.6/0.75=0.8
Answer:
a*b = 0.5
a/b = 0.888...
Step-by-step explanation:
0.6666... = 2/3
a*b = 2/3 * 3/4 = 1/2 = 0.5
a/b = (2/3) / (3/4) = 8/9 = 0.888...
There is a box of cards in front of you with 9 heart cards, 4 spade cards, 7 club
cards, and 8 diamond cards. What is the probability of selecting a heart, not
replacing it, then selecting a spade, not replacing it, and on the third pick,
selecting a card that is not diamond? *
Answer:
heart cards 9/28
spade cards 4/27
diamond card 18/26
Step-by-step explanation:
you have 9 heart cards in all and 28 in all
take one heart out and not replacing you have 27
you have a 4/27 chance of getting spade because you have 4 spades out of 27 cards
now you have 26 cards from taking the one spade & heart out you have a 8/26 chance of getting diamond but a 18/26 chance of getting any other card
es perpendicular 3x+y-9=0 y pasa por el origen (0, 0).
Answer:
[tex]y = \frac{1}{3} x[/tex]
Step-by-step explanation:
Una recta que es perpendicular a la pendiente de una ecuación es la recíproco negativo. de l
a ecuación original.
Primero, este problema está en forma estándar, así que conviértalo a la forma de intersección de pendiente
[tex]3x + y - 9 = 0[/tex]
[tex]3x + y = 9[/tex]
[tex]y = 9 - 3x[/tex]
[tex]y = - 3x + 9[/tex]
Ahora encuentre el recíproco negativo de la pendiente que es -3x
[tex] \frac{ - 3}{1} [/tex]
[tex] - ( - \frac{3}{1} [/tex]
[tex] \frac{1}{3} [/tex]
La pendiente es 1/3, así que sepa que introduzca 0 para nuestro valor X para encontrar nuestro valor y
[tex]y = \frac{1}{3} x[/tex]
[tex]y = \frac{1}{3} (0)[/tex]
y=0

Some people believe there are too many taxes and that tax rates
are too high. They refuse to file tax returns or pay taxes because
they disagree with how the government spends the money. Do you
agree with these arguments? Why or why not?
Answer:
Step-by-step explanation:
(This is technically a personal opinion question) In MY opinion all government run things from libraries to schools to the military come from taxes. If you don't agree with how the government spends the money that you pay in taxes yet enjoy/use government facilities then you have no room to complain and not pay your taxes.

A basketball team played 15 games and won 80% of them. If the team expects to play 30 games in all, how many more games must it win to finish the season with a 90% winning percentage?
Answer: The team needs to win 15 more games to get 90% winning percentage.
Step-by-step explanation:
80%=4/5 divide 15 by 5 and you get 3, which is 1/5 of 15, so you must multiply it by 4 to get 80% of 15 which is 3*4=12
If you want 90%(or 9/10) of 30, you do the same thing, and you get 27.
27-12=15.
The team needs to win 15 more games to get 90% winning percentage

Answer:
x = 70
Step-by-step explanation:
As the problem states, ∠ABD and ∠DBC are supplementary angles. This means they have a sum of 180°. Since we know this, we can set up an equation to solve for x.
x + 110 = 180
x = 70

The number of calories burned by a 90-pound cyclist is proportional to the number of hours the cyclist rides. The equation to represent this relationship is y = 225x. What is the constant of proportionality?
A:135
B:225
C:315
D:90
Answer:
The constant of proportionality is 225
Step-by-step explanation:
Given
[tex]y = 225x[/tex]
Required
Determine the constant of proportionality (k)
A direct proportion is represented as:
[tex]y = kx[/tex]
Where k is the constant of proportionality
By comparing:
[tex]y = kx[/tex] to [tex]y = 225x[/tex]
Hence:
[tex]k = 225[/tex]

Step-by-step explanation:
Mean: 13
Median: 9
Mode: 9
Range: 28
The mean,median,mode and range of the data will be 13,9,9 and 28.
How to find the mean of a data set?Mean is the ratio of the sum of the values of the data set to the total number of values available in the data set.
Thus, we get;
[tex]\rm Mean = \dfrac{\text{Sum of the observations of the data set}}{\text{Total number of observations}}[/tex]
[tex]\rm Mean= \frac{3+25+9+30+9+2}{6} \\\\ Mean=13[/tex]
Arrange the data in the ascending order;
2,3,9,9,25,30
The median of the data set is;
[tex]\rm Median = \frac{9+9}{2} \\\\ Median =9[/tex]
Mode is the value appear most of the time in the data set;
9 is the number repeat two times in the data set.
Mode = 9
Range of the data is the difference of the maximum and the minimum value;
Range=30-2
Range=28
Hence,the mean,median,mode and range of the data will be 13,9,9 and 28.

Step-by-step explanation:
part over whole = part over whole
0.5/20 = p/100
then cross multiply
(0.5)(100) = 20p
50 = 20p
then divide both sides by 20
2.5 = p
To check, change 2.5% to a decimal by dividing by 100, (=0.025) then multiply by 20.
20 x 0.025 = 0.5
