Answer:

525 Minutes

Step-by-step explanation:

The equation would be...

$60 + $0.12m = $123

Now we can simplify

($60 - $60) + $0.12m = ($123 - $60)

$0.12m = $63

($0.12m/$0.12) = ($63/$0.12)

M = 525

Answer:

-59

Step-by-step explanation:

x3 is meaningless; I assume you meant x^3.  

If that's the case, then:

3x + 8 = -4 is equivalent to 3x = -12, so that x = -4.

Then (-4)^3 + 5 = -64 + 5 = -59

Answer:

-59

Step-by-step explanation:

the question can be solved by some simple mathematical steps.

If 3x + 8 = -4

then, x3 + 5 =?

from 3x + 8 = -4

collect the like terms

3x = -4 - 8

3x = -12

divide both sides by 3

3x/3 = -12/3

x = -4

if x = -4 then to find  x3 + 5 will imply that we will insert the value of x = -4 into the x3 + 5

-4 ³ + 5

-64 + 5

= -59

therefore the value of x3 + 5 is solved to be -59

The question is about solving the linear equation 1/10(x+50)=-3x-13+4x. This process involves simplifying the equation, combining like terms, and isolating x to find the solution.

This question involves algebra, specifically the solving of linear equations. To start, your equation is

1/10(x+50)=-3x-13+4x

. First step is to simplify the equation: both sides of the equation need to be simplified and rearranged. After simplifying, we can combine the x terms and constants together. You will then isolate x on one side of the equation by adding or subtracting terms as needed. This will give you the solution to the equation. It's important to remember that the solution to the equation is the value of x that makes both sides of the equation equal. Note that one might end up with no solution if the equation is not consistent after simplifying.

Answer:

1.9 kg

Step-by-step explanation:

Empty container: 3/10 kg = 0.3 kg

Container half filled: 1 1/10 kg = 1.1 kg

Mass of water that fills it halfway: 1.1 kg - 0.3 kg = 0.8 kg

Mass of water that fills it completely: 2 * 0.8 kg = 1.6 kg

Mass of container completely filled with water: 0.3 kg + 1.6 kg = 1.9 kg

The equation of the given circle is [tex](x-6)^{2}+(y+9)^{2}=100.[/tex]

Step-by-step explanation:

Step 1:

The equation of a circle with its center at (h, k) and a radius of r is given by

[tex](x-h)^{2}+(y-k)^{2}=r^{2}.[/tex]

The h value is the x coordinate and the k value is the y coordinates, so (h, k) is (6, -9).

The radius is given as 10 so [tex]r =10[/tex] and [tex]r^{2} = 100.[/tex]

Step 2:

By substituting the values we know, we get

[tex](x-h)^{2}+(y-k)^{2}=r^{2} = (x-6)^{2}+(y-(-9))^{2}=10^{2}.[/tex]

So the equation of the given circle is

[tex](x-6)^{2}+(y+9)^{2}=100.[/tex]

The each class is 64 minutes or 1 hour 4 minutes long.

Step-by-step explanation:

1 hour = 60 minutes.

Time spent in 6 classes :

Time spent in 6 classes = Total time - (lunch period + switching classes)

⇒ 456 - (30+42)

⇒ 456 - 72

⇒ 384 minutes.

The Time for each of 6 classes :

Time for each class = Time spent for all 6 classes / 6

⇒ 384/6

⇒ 64 minutes.

⇒ 1 hour 4 minutes.

Im not sure it depends on the pattern? lol

The pattern described in the table is the value of b is 5 times the value of a.

A pattern is defined as a sequence of repeating objects, shapes or numbers. We can relate a pattern to any type of event or object. A pattern has a rule that tells us which objects belong to the pattern and which objects do not belong to the pattern.

Given is a table,

a - 0 1 2 3 4

b - 0 5 10 15 20,

We can see, that the values in the b row are 5, 10, 15, 20 they are the multiple of 5

And values in row a, are 1, 2, 3, 4, we can see they are the numbers which are related to row b, in a way that, values in b are 5 times the value of a,

1 × 5 = 5

2 × 5 = 10

3 × 5 = 15

4 × 5 = 20

5 × 5 = 25

Therefore, we can say that the numbers in b are 5 times the corresponding value of the a,

Hence, the pattern described in the table is the value of b is 5 times the value of a.

Answer: -6

Explanation: In this problem, we're given the function f(x) = 3x - 12 and we're asked to find f(2).

To find f(2) or the value of the function when x equals 0, we simply substitute 2 in for x in our function. So we have f(x) = 3(2) - 12 or 6 - 12 which equals -6.

So f(2) or the value of the function when x equals 2 is -6.

Answer:

$72.45

Step-by-step explanation:

Add the amounts of the manicure and pedicure together: 28 + 35 = 63

Then find 15% of $63. You will need to find the decimal equivalent of 15%. To do this, divide 15 by 100 or move it two decimal places to the right: 15/100 = 0.15

Now, multiply total of the manicure and pedicure, 63, by 0.15: 63 x 0.15 = 9.45

$9.45 will be her tip. To find the total amount Skylar payed, add the tip to the amount spent on the mani/pedi: 63 + 9.45 = 72.45

Skylar will pay $72.45

Hope this helps!

Final answer:

To calculate Skylar's total payment including a 15% tip for her manicure and pedicure, add the cost of both services ($63) and then calculate the tip ($9.45). The total payment is $72.45.

Explanation:

The student's question involves calculating the total cost of a service which includes both a tip and the original prices of the services purchased - in this case, a manicure and a pedicure. To find how much Skylar will pay after tipping 15%, we first need to calculate the total cost of the services before the tip.

Firstly, we add the cost of the manicure ($28) and the pedicure ($35) to get the total cost before the tip:

Next, we calculate the amount of the tip by multiplying the total cost by the tip percentage (which we convert from 15% to a decimal by dividing by 100):

Finally, we add the original total cost to the tip to find the final amount Skylar will pay:

So, Skylar will pay $72.45 in total for her manicure and pedicure including a 15% tip.

Solution:

Let stamps be s and postcards be p

Given that,

The number of stamps was 4 more than twice the number of postcards

s = 4 + 2p -------- eqn 1

Jason bought both 41-cent stamps and 26-cent postcards and spent $10.28

41 cent = $ 0.41

26 cent = $ 0.26

Therefore,

[tex]s \times 0.41 + p \times 0.26 = 10.28[/tex]

0.41s + 0.26p = 10.28 --------- eqn 2

Substitute eqn 1 in eqn 2

0.41(4 + 2p) + 0.26p = 10.28

1.64 + 0.82p + 0.26p = 10.28

1.08p = 10.28 - 1.64

1.08p = 8.64

Divide both sides by 1.08

p = 8

Substitute p = 8 in eqn 1

s = 4 + 2(8)

s = 4 + 16

s = 20

Thus Jason bought 20 stamps and 8 post cards

Answer:

-8.5, or -8 1/2

Step-by-step explanation:

Put it into an improper fraction: -17/4

Multiply: -17/4 * 2/1 (To divide, multiply by reciprocal)

= -34/4

Simplify: -17/2, or -8 1/2

Answer:

-34/4    or -8 1/2

Step-by-step explanation:

First we want to put -4 1/4 so its all a fraction we do this by multiplying 4 to 4 and adding it to the 1 already in the fraction (We can ignore the sign and just add it to the fraction because the entire fraction is negative not just the 4). So we have -17/4

To divide fractions we use keep change flip it is an easier way to divide fractions with out making decimals. We keep the first fraction change the division into multiplication and flip the last fraction, in this case 1/2 becomes 2/1. Now we have

-17/4 * 2/1  

Our next step is to multiply the numerators together and the denominators together and then put it back in fraction form.

-17 * 2 = -34

4 * 1 = 4

Our final result is

-34/4        

Or if you need it as a mixed number you just divide the 34 into 4 as many times as you can and make that the whole number. 34 doesn't completely fit into 4 but 32 does so we have

-8 2/4      or simplified further

-8 1/2

Answer:

the value of x and y is 3 and -1 respectively.

Step-by-step explanation:

from the question

let

2x + 3y = 3........................ equation 1

y = 8 - 3x.............................. equation 2

put y = 8 - 3x in equation 1

2x + 3y = 3........................ equation 1

2x + 3 ( 8 - 3x) = 3

2x + 24 - 9x = 3

24 - 7x = 3

24  = 3 + 7x

24 -3 = 7x

21 = 7x

divide both sides by 7

x = 3

put x = 3 in equation 2

y = 8 - 3x.............................. equation 2

y = 8 - 3 ( 3)

y = 8 -9

y = -1

therefore the value of x and y is 3 and -1 respectively.
