$18.40 is hourly rate in dollars after the increase

Answer:QR = 54

Step-by-step explanation:

Answer:

18

Step-by-step explanation:

The GCF is also known as the greatest common factor. Every number can be written as the product of at least 2 numbers, and almost every number has at least one factor that is a prime number (or a number that is only divisible by 1 and itself).

Let's find the prime factorization of 18 and 72; in other words, let's find what prime numbers make these numbers up.

18 = 2 * 9 = 2 * 3 * 3  ⇒  notice that while 9 isn't a prime number, 2 and 3 are

72 = 2 * 36 = 2 * 2 * 18 = 2 * 2 * 2 * 3 * 3  ⇒  again, 2 and 3 are primes

In finding the GCF, we want to find the largest value of the prime numbers that the two numbers share.

Here, we see that both 18 and 72 have at least one factor of 2 and at least two factors of 3. So, that's the greatest common factor: 2 * 3 * 3 = 18.

Answer:

I think answer is 87<180 or maybe 87<12*15

The scatterplot that best represent a linear relationship between the variables, X and Y, is: graph C.

On a scatterplot, the trendline that shows a linear relationship between two variables will have a straight line pattern that either slopes up or down.

The scatter plot in graph C shows a trendline that slopes along a straight line. Therefore, the answer is C.

Answer:

57.60

Step-by-step explanation:

Multiply $64 by .1 which is the decimal form of 10%. You should get 6.4. Then you subtract 6.4 from 64, you get 57.60.

Answer:

Option (2)

Step-by-step explanation:

Arrow shown on the left hand side of the number line represents the inequality,

x < 5 [No sign of 'equal to' because arrow starts with a hollow circle]

Arrow given on the right hand side of the number line will represent,

x > 18

And these arrows represent the two solution areas of x, so the composite inequality that represents the graph will be,

x < 5 or x > 18

Option (2) will be the answer.

Answer:

(-7)2 = -14

Step-by-step explanation:

The parenthesis basically mean "multiply". So, this is a simple equation meaning -7 x 2. And remember, anytime we multiply a positive by a negative, you get a negative. So, simply multiply 7 x 2 = 14 and add a negative sign to make the solution true. So, -7 x 2 or (-7)2 = -14

Hope this helps! If you have any additional questions, please don't hesitate to ask me or your teacher to be sure you master the subject. Also thank you for the generous points!! Stay safe and please mark brainliest!!

Answer:

-14

Step-by-step explanation:

just act as if -7 were positive then you know 7x2 = 14 cause' "()" means multiplication.

last, since 7 was negative in the first place then you turn your product back to a negative and you get -14

Answer:

x = 6

Step-by-step explanation:

[tex]\frac{-2}{3}x+9=\frac{4}{3}x-3\\\\\frac{-2}{3}x-\frac{4}{3}=-3-9\\\\\frac{-2-4}{3}x= - 12\\\\\frac{-6}{3}x = -12\\\\ -2x -12\\\\x = \frac{-12}{-2}\\\\x = 6[/tex]

Answer:

m=15d-300

Step-by-step explanation:

Answer:

300-15d = m

Step-by-step explanation:

Since he spends 15 each day, we dont know how many days, so we put 15d to represent $15 spent each day (d)

We use this formula above ^ and subtract that from 300, which is why it's

300 - 15d

Lastly, we need to find money remaining, so 300 - 15d = m

Answer:

64

Step-by-step explanation:

4 cubed is 64 because 4 cubed can be written as an exponentiation, where the base is 4 and the exponent is 3, like this: 43. For future reference, note that cubed means that the exponent is 3 regardless of what the base is. When the exponent is 3 (aka cubed) and the base is 4 you simply multiply 4 by 4 by 4 to get the answer 64
