Determine whether the following system of equations has one solution, no solution, or an infinite number of solutions. Explain your reasoning.
2x - 4y = 10
7x - 9y = 12
Answer:
One solution. The lines do not have the same slope (so not parallel) and are not the same line (so not infinitely many solutions). It intersects at one point, therefore it has one solution.

You are making a colorful cake for a birthday party and need to use 4 drops of food coloring for every 5 ounces of icing. How many drops of food coloring do you need if
you are using 30 ounces oficing?
Answer:
24 drops of food coloring
Step-by-step explanation:
First, since there are 30 ounces, divide by 5, because there are 4 drops in every 5 ounces of icing. Since 30÷5=6, You have to multiply it by 4 to get 24. You multiply by 4 because there are 4 drops in 5 ounces of icing.
24 drops of food colouring are needed if you are using 30 ounces oficing.

If sin theta <0 and tan theta >0 then:
Answer:
Step-by-step explanation:
If the sine is negative then theta must be in Quadrant III or Quadrant IV.
If the tangent is positive then theta must be in Quadrant I or III.
If both conditions must be satisfied, then we conclude that thera is in Quadrant III.
Note that [tex]\tan\theta=\frac{\sin\theta}{\cos\theta}.[/tex] Thus, if [tex]\sin\theta<0[/tex] and [tex]\tan\theta>0,[/tex] then we must have [tex]\cos\theta<0[/tex] as well. The sine function is negative when [tex]\theta[/tex] lies in Quadrant III or IV, and the cosine function is negative when [tex]\theta[/tex] lies in Quadrant II or III. Thus, the two are both negative when [tex]\theta[/tex] lies in Quadrant III, or [tex]\pi+2\pi n<\theta<\frac{3\pi}{2}+2\pi n[/tex] for integer values of [tex]n.[/tex]

The solution of 2x -3=7
Answer: x = 5
Step-by-step explanation: To solve for x, we must first isolate the term containing x which in this problem is 2x.
Since 3 is being subtracted from 2x, we add 3
to both sides of the equation to isolate the 2x.
On the left, the -3 and +3 cancel
out and on the right, 7 + 3 is 10.
So we have 2x = 10.
No we can finish things off by just dividing
both sides of the equation by 2.
On the left the 2's cancel and on
the right, 10 divided by 2 is 5.
So we have x = 5.
The annual median income for a registered nurse is $65,000. The annual median income for a registered dietitian is $54,000. Over 20 years, how much more than a registered dietitian can a registered nurse earn?
Answer:
$220,000
Step-by-step explanation:
Given;
The annual median income for a registered nurse = $65,000
The annual median income for a registered dietitian = $54,000
The difference in the annual income of the registered dietitian from Nurse;
d = 65,000 - 54,000
d = $11,000
In 20 years, the cumulative difference in their earnings is;
Td = 20 × $11,000
Td = $220,000
Therefore, in 20 years the registered nurse will earn $220,000 more than the registered dietitian.

Answer:
c.
Step-by-step explanation:
P(male) = 100 - 54 = 46% = 0.46
P(male & senior) = 0.46 × 0.3 = 0.138
13.8 %
Answer:
C. 13.8%
Step-by-step explanation:
P(male) = 100 - 54 = 46% = 0.46
P(male & senior) = 0.46 × 0.3 = 0.138
= 13.8%

Wayne Gretzky holds the NHL record for the most points scored In a career. He scored 2857 points in 1487 games. a. Calculate his average points per game b. At this rate,how many more points might he have scored if he had played 79 more games?
Answer:
Step-by-step explanation:
a) The formula for determining average is expressed as
Average point per game = number of points scored/total number of games played
Average point per game = 2857/1487 = 1.92
b) if he had played 79 more games, since his average point per game is 1.92, then the number of points that he might have scored would be
1.92 × 79 = 95 points
The total number of points would have been
2857 + 95 = 2952 points
Answer:
a. 1.92
b. 152
Step-by-step explanation:
Wayne Gretzky had 2857 points in 1487 games.
a. His average points per game can be determined by dividing the total number of points by number of games. So that:
average points per game = [tex]\frac{2857}{1487}[/tex]
= 1.92132
Therefore, he scored an average of 1.92 (2 d.p) points per game.
b. The number of points he would have scored having played 79 more games can be determined by multiplying the points for 79 more games by his average points.
His points for 79 more games = 79 × 1.92132
= 151.78428
He would have scored 152 (3 s.f) more points if he had played 79 more games.

I opened a grocery account at my bank with $250. Every week thereafter, I withdraw $90 from the account to pay for groceries. If x is the number of weeks I've had the account, then y is the amount in the account. Find an equation of a line in the form y = mx + b that describes my grocery account balance.
Answer:
y= -90x+250
Step-by-step explanation:
From the information given, the equation would be that the amount in the account would be equal to -90 that is the amount you withdraw from the account each week multiply for x that is the number of weeks plus $250 that is your initial balance:
y= -90x+250, where
y= amount in the account
x= number of weeks.
