Answer:

80 pages

Step-by-step explanation:

If Joe has read 30% and 56 pages is 70% of the book. We divide 56 by 7 and get 8 meaning that 10% of the book is 8. Once we know this we multiply 8 x 10 and get the amount of pages in the book 80

Answer:

There are 80 pages left.

Step-by-step explanation:

100% - 30% = 70%

70% = 56 pages

Insert x into a equation.

0.7x = 56

Multiply by 10 on both sides to get rid of the decimal.

0.7x = 56

· 10     ·10

Divide by 7 on both sides to get x by itself.

7x = 560

     7

x = 80

Answer:

k=1

Step-by-step explanation:

According to the remainder Theorem, if we have a polynomial then if it divided by (x-a), the remained will be equal to

[tex]f(a)[/tex]

So we know that the factor is

[tex](x - k)[/tex]

So plug in k into the polynomial

[tex]f(k) = k {}^{3} + k(k) {}^{2} - 2(k) + 1 = k[/tex]

[tex]k {}^{3} + k {}^{3} - 2k + 1 = k[/tex]

[tex]2k {}^{3} - 3k + 1 = 0[/tex]

Solve for k.

Using Rational Roots Theorem, one possible root is 1 so we have

[tex]2k {}^{2} + 2k - 1 = 0[/tex]

Since that is irreducible over reals, 1 is our only factor so k=1.

Answer:

y = -2x + 1

Step-by-step explanation:

The linear equation is generally written in y = mx + b form. Since m (the value of the slope) is already given, only the value of b must be determined. To do this, plug in x, y, and m for their values in the equation to get:

13 = -2 (-7) + b

Then, simplify.

13 = 14 + b

b = -1

Once you find the b value, plug everything back in and get y = -2x + 1.

Answer:

Answer:

Step-by-step explanation:

Time per mile can be found by dividing hours by miles:

  (1/8 h)/(3/8 mi) = 1/3 h/mi

It will take him 1/3 hour to run 1 mile.

__

Miles per hour can be found by dividing miles by hours (or by finding the reciprocal of the above value):

  (3/8 mi)/(1/8 h) = 3/1 mi/h = 3 mi/h

He could run 3 miles in one hour.

Step-by-step explanation:

If you have 3 and you take away 4, so you end up with a negative number. or what you can do is also just flip the numbers around so subtract 4 minus 3 and put a negative sign when the first number is less than the second one!!

Using the normal distribution, it is found that 6.3% of people received a higher score than Jose.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are given by, respectively: [tex]\mu = 76.28, \sigma = 7.02[/tex].

The proportion of people who received a higher score than Jose is one subtracted by the p-value of Z when X = 87, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{87 - 76.28}{7.02}[/tex]

[tex]Z = 1.53[/tex]

[tex]Z = 1.53[/tex] has a p-value of 0.937.

1 - 0.937 = 0.063.

6.3% of people received a higher score than Jose.

Using the distance between two points to find the length of the side of the square, it is found that:

The distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

In this problem, the length of the side of the square can be found as the distance between points G and H, that is, the distance between (0,5) and (-5,0), hence:

[tex]l = \sqrt{(0 - (-5))^2 + (5 - 0)^2} = \sqrt{50} = \sqrt{2 \times 25} = 5\sqrt{2}[/tex]

The area of a square of side length l is given by:

[tex]A = l^2[/tex]

Hence:

[tex]A = (5\sqrt{2})^2 = 50[/tex]

The area is of 50 square units.

The perimeter of a square of side length l is given by:

[tex]P = 4l[/tex]

Hence:

[tex]P = 4(5\sqrt{2}) = 20\sqrt{2}[/tex]

The perimeter is of [tex]20\sqrt{2}[/tex] units.

Answer:

c; infinite solutions

Step-by-step explanation:

to solve this system of equations you can use elimination

you can divide all of the top by 2

you get

3x + y = 6

and then

-3x - y = -6

but then when you subtract them you get 0 = 0

this means it is infinite solutions

another way to tell that it is infinite solutions is by seeing if the equations are the same

-3x - y = -6 is just 3x + y = 6 but everything is multiplied by -1

Answer:

INFINITE SOLUTIONS

Step-by-step explanation:

So let's solve this system using elimination

we can convert the second equation to

-6x-2y = -12

6x+2y = 12

if we add these to equations we get 0 = 0

therefore, there are infinite solutions to this system
