Answer

It will take him 450 minutes to read 90 pages.

Explanation

Luis can read 3 pages every 15 minutes.

You are trying to find how long it will take him to read 90 pages.

Set up this ratio.

$\frac{15}{3} =\frac{x}{90}$

To get from 3 to 90, you multiply by 30. Do the same thing to 15.

15 times 30 is 450.

It will take Luis 450 minutes to read 90 pages.

What is the product of a,b, and c?

Yuri [45]

Answer:

$abc = - \frac{16}{3}$

Step-by-step explanation:

${x}^{ - 2} {y}^{3} \sqrt[3]{ 64{x}^{5} {y}^{3} } = a {x}^{b} {y}^{c} \\ \\ {x}^{ - 2} {y}^{3} \times 4 \times {x}^{ \frac{5}{3} } \times y= a {x}^{b} {y}^{c} \\ \\ 4 {x}^{ \frac{5}{3} - 2 } {y}^{3 + 1} = a {x}^{b} {y}^{c} \\ \\ 4 {x}^{ \frac{5 - 6}{3} } {y}^{4} = a {x}^{b} {y}^{c} \\ \\ 4 {x}^{ \frac{ - 1}{3} } {y}^{4} = a {x}^{b} {y}^{c} \\ \\ equating \: like \: terms \: on \: both \: sides \\ \\ a = 4 \\ \\ b = - \frac{1}{3} \\ \\ c = 4 \\ \\ abc = 4 \times ( - \frac{1}{3} ) \times 4 \\ \\ = 16 \times ( - \frac{1}{3} ) \\ \\ abc = - \frac{16}{3}$

10 cards are numbered from 1 to 10 and placed in a box. One card is selected at random and is not replaced. Another card is then

Elena L [17]

First you need to know the prime numbers from 1-10.
They are 2, 3, 5, 7,
1st draw: P(prime) = 4/10
2nd draw: P(prime) = 3/9
Multiply these numbers 12/90 = 2/15

Only the math gods can write this 50 PT proof!

fredd [130]

Answer:

because the 1st corner and the 2nd corner is places in a straight line which the total agle is 180° so since the 1st corner has same angle as the 13th one the 14th is must be have same angle as the 2nd corner. so that the 1st corner + the 14th corner is equal as 180°

3x-2y=-1. <br> Y=-x+3. <br> Is (1,2) a solution do the system?

andrew-mc [135]

Answer:

Yes

Step-by-step explanation:

To figure out if (1,2) is a solution to the system, we can plug the values in and see if it is true.

3x-2y=-1

3(1)-2(2)=-1

3-4=-1

-1=-1

It is true for this equation. Now let's check the next one.

y=-x+3

2=-(1)+3

2=2

Since both equations are true when we plug the values in, (1,2) is a solution to the system.
