Annette earns $30 in 2 hours and Carla earns $96 in 6 hours. Who has the
higher hourly rate?
A
Answer:
Carla
Step-by-step explanation:
First we need to find the hourly rate for Annette
Take the dollars earned and divide by the number of hours
30/2 = 15 dollars per hour
Now we can find the hourly rate for Carla
96/6 =16 dollars per hour
Carla has the higher hourly rate since she earns more per hour

Mei Mei left her house at time zero and drove for 4 minutes to the store, at a speed of 2 blocks per minute. Then she stopped and went into the store for 5 minutes. From there, she drove in the same direction at a speed of 5 blocks per minute until she got to the bank, which is 10 blocks away from the store. She stopped at the bank for 2 minutes. Then she drove home at a speed of 3 blocks every minute. Make a graph of showing the number of blocks away from home that Mei Mei is xx minutes after she leaves her house, until she gets back home.
The graph for Mei Mei' trip is attached accordingly. Also attached are the values derived from the question.
What is the explanation for the graph?The secret to comprehending the graph is to understand that every time Mei Mei spent while she was on the way to bank and back were are all computed cumulatively.
This means that when she stops at the store which is 8 blocks away from home (that is 2 blocks per min x 4 mins = 8blocks) the time spent is recorded as 4 + 5 at location 8 blocks, which is equals 9 minutes.
Also take note of the fact that the time spent is plotted on the x-axis and the blocks away from home on the y-axis.

FIND X AND Y. PLEASE HELP! I WILL GIVE BRAINLIEST!!!
Answer:
x = 20, y = 60
Explanation:
Angles which lie in a straight line sum ups to 180°
3x + 3x + 3x = 180
9x = 180
x = 180/9
x = 20
Using the same theorem,
3x + y + 3x = 180
3(20) + y + 3(20) = 180
60 + 60 + y = 180
120 + y = 180
y = 180 - 120
y = 60
or
y = 3x
y = 3(20)
y = 60
The value of x is 20° and the value of y is 60°.
What is the vertical angles theorem?According to this theorem, when two straight lines cross, they create two sets of linear pairs with matching angles. The adjacent angles created by the junction of these two lines are likewise said to be supplementary, or equivalent to 180 degrees.
As per the vertical angles theorem and vertical angles theorem,
the two angle equations as per the opposite angle and supplementary angles.
3x + 3x + 3x = 180
9x = 180
x = 180/9
x = 20
And another equation can be described as,
3x + y + 3x = 180
6x + y = 180
6(20) + y = 180
y = 180 - 120
y = 60
Therefore, x = 20 degrees and y = 60 degrees.

You own a catering company and are in charge of an engagement party. There are two dinners: a chicken dish, which costs $40, and a lobster dish, which costs $70. The 250 party guests have ordered their meals in advance, and the total cost to prepare the dinner is $13 570. How many of each type of dinner are you preparing?
The number of chicken dish is 131 dishes while the number of lobster dishes is 119 dishes
How to find the number of each type of dish.Let
x = number of chicken dish and y = number of lobster dishHow to determine the equations for the linear systemSince it cost $40 per dish for chicken dish, the total cost of chicken dish is 40x.
Also, since it cost $70 per dish for lobster dish, the total cost of lobster dish is 70y
So, the total cost of dish is T = 40x + 70y
Also, we know that the total cost of dish is $13,570.
So, 40x + 70y = 13570 (1)
Also, there are going to be 250 guest at the dinner and thus 250 dishes.
So, the total number of dishes is x + y = 250
So, x + y = 250 (2)
So, the equations of the linear system are
40x + 70y = 13570 (1)
x + y = 250 (2)
How to determine the solution for the linear systemSince
40x + 70y = 13570 (1)
x + y = 250 (2)
From (2), x = 250 - y
Substituting x into (1), we have
40x + 70y = 13570 (1)
40(250 - y) + 70y = 13570 (1)
10000 - 40y + 70y = 13570
30y = 13570 - 10000
30y = 3570
y = 3570/30
y = 119
Substituting y = 119 into x, we have
x = 250 - y
x = 250 - 119
x = 131
Therefore, the number of chicken dish is 131 dishes while the number of lobster dishes is 119 dishes

If a^2 and b are directly proportional, and a=2 when b=9, then what is b when a=6?
Answer:
b = 81
Step-by-step explanation:
given a² and b are directly proportional then the equation relating them is
a² = kb ← k is the constant of proportionality
to find k use the condition a = 2 when b = 9 , then
2² = 9k
4 = 9k ( divide both sides by 9 )
[tex]\frac{4}{9}[/tex] = k
a² = [tex]\frac{4}{9}[/tex] b ← equation of proportion
when a = 6 , then
6² = [tex]\frac{4}{9}[/tex] b
36 = [tex]\frac{4}{9}[/tex] b ( multiply both sides by 9 to clear the fraction )
324 = 4b ( divide both sides by 4 )
81 = b
