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.

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.

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.
Son of Hannah‘s plants need water every day some need water every other day and some need water every third day if she what is an all today how many days will it be before she waters them all again
Answer:
3 days
Step-by-step explanation:
Some of Hannah‘s plants need water every 1 day.
Some need water every third(3) day.
If she waters them all today, we are to determine when next she will waters them all again.
To do this, we find the lowest common multiple of 1 and 3.
L.C.M of 1 and 3=3
Therefore, in 3 days time, she will water them all again.
Pls help, Which shows how to solve the equation Three-fourths x = negative 6 for x in one step?
A.Three-fourths (four-thirds) x = negative 6 (four-thirds)
B.Three-fourths (4) x = negative 6 (4)
C.Three-fourths (4) x = negative 6 (3)
D.Three-fourths (four-thirds) x = negative 6 (three-fourths)
Answer:
answer A is correct
Step-by-step explanation:
3/4 * x = - 6
4/3 * 3/4 * x = 4/3 * - 6. This is answer A
12/12 * x = -24/3
1 * x = - 8
x = - 8
So you see answer A is correct.
Answer:
The correct answer is A
Bob is performing an experiment to learn more about probability. He has a box of pink, yellow, blue, and white ribbons. He randomly picks a ribbon from the box and then replaces it. He does this 100 times. The table shows the number of times he picks a ribbon of each color. Ribbon Color Number of Times Picked pink 10 yellow 20 blue 40 white 30 The relative frequency of picking a pink ribbon is . The relative frequency of picking a white ribbon is . It is most likely that the number of ribbons in the box is the highest. It is most likely that the number of ribbons in the box is the lowest
Answer:
1. 0.1
2. 0.3
3. blue
4. pink.
Step-by-step explanation:
Got it right, hope this helps! :)
The blue ribbon was picked the most with a relative frequency of 40%, which means it is most likely that there are more blue ribbons in the box than the other colors.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The relative frequency of picking a pink ribbon is found by dividing the number of times a pink ribbon was picked by the total number of times Bob picked a ribbon:
Relative frequency of pink ribbon = 10/100 = 0.1 or 10%
Similarly, the relative frequency of picking a white ribbon is:
Relative frequency of white ribbon = 30/100 = 0.3 or 30%
To determine which ribbon color is most likely to be the highest or lowest, we can compare the relative frequencies.
The blue ribbon was picked the most with a relative frequency of 40%, which means it is most likely that there are more blue ribbons in the box than the other colors.
Conversely, the pink ribbon was picked the least with a relative frequency of 10%, which means it is most likely that there are fewer pink ribbons in the box than the other colors.
Hence, the blue ribbon was picked the most with a relative frequency of 40%, which means it is most likely that there are more blue ribbons in the box than the other colors.
