Every musician in the band plays either the flute or the drum (but not both). The ratio of flutists to drummers is 7 : 1. If 2 drummers join the group and 6 flutists quit, the ratio of flutists to drummers would be 3 : 1. How many musicians were in the original ensemble? 4. A sloth is swimming in the Charles River at 20 feet per minute. How fast is the sloth swimming in smoots per hour? One smoot is equal to 5 feet, 7 inches. Write your final answer as a simplified fraction.
Answers
Answer:
Number of drummers in original ensemble [tex]=3[/tex]
Number of flutists in original ensemble [tex]=21[/tex]
Step-by-step explanation:
The ratio of flutists to drummers is [tex]7:1[/tex]
Let number of flutists and drummers be [tex]7x[/tex] and [tex]x[/tex].
As 2 drummers join the group and 6 flutists quit,
Number of drummers = [tex]x+2[/tex]
Number of flutists = [tex]7x-6[/tex]
New ratio of flutists to drummers = [tex]3:1[/tex]
So,
[tex]\frac{7x-6}{x+2}=\frac{3}{1}\\ 7x-6=3(x+2)\\7x-6=3x+6\\7x-3x=6+6\\4x=12\\x=3[/tex]
So,
Number of drummers in original ensemble [tex]=x=3[/tex]
Number of flutists in original ensemble [tex]=7x=7(3)=21[/tex]

Answers
[tex]4x - 5 = x + 16[/tex]
Subtract the sides of the equation plus 5
[tex]4x = x + 16 + 5[/tex]
[tex]4x = x + 21[/tex]
Subtract the sides of the equation minus x
[tex]3x = 21[/tex]
Divided the sides of the equation by 3
[tex] \frac{3}{3} x = \frac{21}{3} \\ [/tex]
[tex]x = 7[/tex]
So the measure of the angle equals :
[tex]4(7) - 5 = 28 - 5 = 23 [/tex]

A rate is a ratio that compares
Answers
Rate is ratio that compares two quantities of different units.
What is rate?A rate is a special ratio in which the two terms are in different units. Rate can also be defined as the ratio between two quantities of different units
For example, velocity is an example of rate, because it defined by the ratio of distance covered and time.
The unit of distance is metres and the unit of time is second. Therefore ;
velocity = distance /time. Therefore velocity is a rate.
Another example is ; Ade eat 5 mangoes for 20 days. The rate at which Ade eat is

Step-by-step explanation:
Correct for Plato Users
The equation has 4 solutions and its real solutions are 3, -1.
The given polynomial equation is 6(x - 3)(x² + 4)(x + 1) = 0.
What does a real solution mean in math?A real solution in algebra is simply a solution to an equation that is a real number.
Now, 6(x - 3)(x² + 4)(x + 1) = 0
⇒(x - 3)(x² + 4)(x + 1) = 0
⇒(x - 3)=0, (x² + 4)=0 and (x + 1) = 0
⇒x=3, -1 and ±√-4.
Therefore, the equation has 4 solutions and its real solutions are 3, -1.

Answers
80 − 64 = 16
Now we need this difference as a percentage:
16
64
×
100
=
25 %
Explanation:
We divide by 64 because we want to know how much the number has changed from its original value.
We multiply by 100 because 'per cent' means 'how many out of 100'.
Explanation:
The formula for calculating the percent change in a value between two points in time is:
p=N−O/ O⋅ 100
Where:
p is the percent change - what we are solving for in this problem.
N is the New Value - 80 in this problem.
O is the Old Value - 64 in this problem.
Substituting and solving for
p gives:
p = 80 − 64/ 64 ⋅ 100
p = 16 /64 ⋅100
p = 1600 / 64
p = 25
The percentage change between 64 and 80 is a 25% increase.

Lorenzo has 4 packages of granola bars. Each package has 10 bars. He eats one bar from each package.
Answers
Answer:
4x10-4=36
Step-by-step explanation:
Lorenzo ate 1 bar from each. so 36 is left.
Answer:
4 × 10 - 4 = 36 granola bars
Step-by-step explanation:
4 packages with 10 bars each means 40 bars (4 packages × 10 bars each = 40 bars total)
one bar from each package
there are 4 packages so if he eats only one from each then he eats 4 bars total
40 bars total - 4 bars he ate = 36 bars left over
