Answer:

27

Step-by-step explanation:

Answer:

$27

Step-by-step explanation:

substitute the value of p (price of the package of henna powder) which has been given as $12 and the value of s (price of the squeeze bottle) which has been stated as $3 into the equation from part b).

since the equation is 3(p-5) + 2s

write 12 instead of p, and 3 instead of s.

then solve the equation.

= 3(12-5) + 2(3)

= 3(7) + 2(3)

= 21 + 6

= 27

2 7/15 i think brainlest

Step-by-step explanation:

Answer:

2 7/15

Step-by-step explanation:

2 2/5 + 1/15

Turn them into improper fractions.

12/5+1/15

In order to add fractions, they need the same denominator.

12/5x3/3=36/15

36/15+1/15=37/15

=2 7/15

The range and the domain of the graph are the sets of non-negative real numbers, while the equation relating p and w is [tex]p = 300 * 3^w[/tex]

From the graph, we have the following ordered pairs

(1,900) and (3,8100)

An exponential function is represented as:

[tex]p = ab^w[/tex]

At the point (1,900), we have:

ab = 900

At the point (3,8100), we have:

ab^3 = 8100

Divide both equations

[tex]\frac{ab^3}{ab} = \frac{8100}{900}[/tex]

Evaluate the quotients

[tex]b^2 = 9[/tex]

Take the square roots of both sides

b = 3

Recall that:

ab = 900

So, we have:

3a = 900

Solve for a

a= 300

Hence, the equation is:

[tex]p = 300 * 3^w[/tex]

Step-by-step explanation:

3. Cross multiply: -6m=90

Solve: m= -15

4. Cross multiply: 7x+7=10x-20

Solve: x=9

Step-by-step explanation:

Here,

-m=10*9/6

Answer:

Hello

Step-by-step explanation:

You can take away the decimals

for example 0.33 x 0.7

do 33 x 7

which is 231

the 0.33 has 2 decimal spaces because there are 2 digits after the point

0.7  has 1 decimal place because there is 1 digit after the point.

so in total, there is 3 decimal

because you do 2 + 1

3

from the left, you count backwards and add the decimal point

the final answer should be 0.231

Step-by-step explanation:

Answer:

8 hours.

Step-by-step explanation:

1. Subtract  640-224=416

2. Divide 416/52

3. 8 hours

8 hours.

Step-by-step explanation:

We have been given that Max is averaging 52 miles per hour and the trip is 640 miles total. Max is already 224 miles into his road trip.

Let us find the remaining distance of trip by subtracting the distance already covered from total distance.

Remaining Distance = 640 miles - 224 miles

Remaining Distance = 416 miles

We will use formula: Time = Distance/Speed to find the number of hours Max still have to drive.

Time = 416 miles/52 miles/hour

Time = 416 miles/52 × hour/miles

Time = 416/52 hour

Time = 8 hours

Therefore, Max have left 8 more hours to drive.
