Answers

Answer:

This equation has 4 solutions, its real solutions are x = -1 and 3

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.

Find the measure of the angle.

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 :

Find the percent of change: original:80 new:64

Answers

First we need to know the difference between them:
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.
So it’s 2

A rate is a ratio that compares

Answers

A rate is a ration that compares two quantities that have different units of measure. If the second term in rate is 1, the ratio is called a unit rate.

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

x = -12

Step-by-step explanation:

x-2(x+1)+3(x+2) = x-4 (equation)

x-2x+2+3x+6 = x-4 (simplify)

x+8 = -4 (subtract x from both sides)

Chris rented truck for one day. There was a base fee of $16.99, and there was an additional charge of 93 cents for each mile
driven. Chris had to pay $227.17 when he returned the truck. For how many miles did he drive the truck?

Answers

Answer:

226 miles

Step-by-step explanation:

Sorry this question couldn't be answered sooner, but here is the answer now:

In order to solve this, we must first subtract the total Chris paid by the base fee:

227.17 - 16.99 = 210.18

Then, we divide this number by 0.93:

210.18 / 0.93 = 226

So, Chris drove the truck 226 miles

Every musician in the band plays either the flute or the drum (but not both). The ratio of flutists to drummers is 7 : 1.

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]

Answer:

Step-by-step explanation:

4 packages with 10 bars each means 40 bars (4 packages × 10 bars each = 40 bars total)

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
