Step-by-step explanation:

Answer:

41

Step-by-step explanation:

A pair of consecutive numbers is written as: N and N + 1

(where the larger page number is N + 1)

And we know that the product of these numbers is 1640.

Then:

(N)*(N + 1) = 1640

Solving for N, we get:

N^2 + N = 1640

N^2 + N - 1640 = 0

This is a quadratic equation, remember that for a general quadratic equation:

a*x^2 + b*x + c = 0

The solutions are:

[tex]x = \frac{-b\pm \sqrt{b^2 - 4*a*c} }{2*a}[/tex]

In our case, the solutions are:

[tex]N = \frac{-1 \pm \sqrt{(1)^2 - 4*1*(-1640)} }{2} = \frac{1 \pm 81}{2}[/tex]

Then the two solutions are:

N = (-1 + 81)/2 = 40

N = (-1 - 81)/2 = -41

Because N represents the number on a page, it only can be a positive value, then we take the positive solution.

Then the two consecutive numbers, N and N + 1

are:

N = 40

N + 1 = 41

The value of the larger page number is 41.

Answer:

42.71

Step-by-step explanation:

268.26-12.00=256.26 total owed

256.26/6 payments =42.71

Answer:

Below.

Step-by-step explanation:

You need to know the volume or total surface area of the prism and 2 of the dimensions.

The formula for the volume = wlh   where w = width , l = length and h = height.

So knowing say w = 4, l = 8 and V =  192 we have:

V = wlh

192 = 4 * 8 * h

h = 192/4*8

= 192/32

= 6.

Answer:

y = - [tex]\frac{7}{4}[/tex] x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - [tex]\frac{7}{4}[/tex] and c = 5 , then

y = - [tex]\frac{7}{4}[/tex] x + 5 ← equation of line

Answer:

x = 5

Step-by-step explanation:

Simplify the like terms:

15x - 8x = 7x

so, 7x = 35

divide: 35/7 = 5

x=5

here are 8 different possible outcomes in the sample space. There are 2 outcomes for the coins, heads and tails. And 4 colors for the spinner.

If you put them together, you have:

The distributive property indicates that multiplying a number by the sum of two addends is equal to multiplying each addend individually by the number and then adding the products together.

In general terms:

In this exercise:

Let's apply the distributive property:

[tex]\mathsf{2(3w - 5y)}[/tex]

[tex]= \mathsf{2(3w) - 2(5y)}[/tex]

[tex]= \boxed{\mathsf{6w - 10y}}[/tex]

Given:

The worlds largest flower, the Rafflesia, has a circumference of 286 centimeters.

To find:

The diameter of the flower.

Solution:

We know that, the circumference of a circle is:

[tex]C=2\pi r[/tex]

Where, r is the radius.

[tex]C=(2r)\pi [/tex]

[tex]C=d\pi [/tex]                            [tex][\because 2r=d][/tex]

Where, d is the diameter.

Putting [tex]C=286, \pi=3.14[/tex] in the above formula, we get

[tex]286=d(3.14)[/tex]

[tex]\dfrac{286}{3.14}=d[/tex]

[tex]91.0828=d[/tex]

[tex]d\approx 91.08[/tex]

Therefore, the diameter of the flower is about 91.08 centimeters.

Answer:

J: (-3,1) K: (4,2) L: (3,-4)

Step-by-step explanation:

Answer:

Step-by-step explanation:

7. <A + <B = 180° [Since Co-interior angles]

=> 51° + <B = 180°

=> <B = 180° - 51°

=> <B = 129° (Ans)

8. <M + <N = 180° [Since Co-interior angles]

=> 95° + <N = 180°

=> <N = 180° - 95°

=> <N = 85° (Ans)

Given:

[tex]\text{cosec}\theta -\cot \theta =\dfrac{1}{M}[/tex]

To find:

The value of [tex]\text{cosec}\theta +\cot \theta [/tex].

Solution:

We have,

[tex]\text{cosec}\theta -\cot \theta =\dfrac{1}{M}[/tex]

We know that,

[tex]\text{cosec}^2\theta -\cot^2 \theta=1[/tex]

It can be written as:

[tex](\text{cosec}\theta -\cot \theta)(\text{cosec}\theta +\cot \theta)=1[/tex]

[tex]\dfrac{1}{M}\times (\text{cosec}\theta +\cot \theta)=1[/tex]

[tex]\text{cosec}\theta +\cot \theta=1\times M[/tex]

[tex]\text{cosec}\theta +\cot \theta=M[/tex]

Therefore, the value of [tex]\text{cosec}\theta +\cot \theta [/tex] is [tex]M[/tex].

Answer:

x = 9

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 6) and (x₂, y₂ ) = (x, - 5 )

m = [tex]\frac{-5-6}{x-2}[/tex] = [tex]\frac{-11}{x-2}[/tex] , then

[tex]\frac{-11}{x-2}[/tex] = - [tex]\frac{11}{7}[/tex] ← numerators are equal, so equate the denominators

x - 2 = 7 ( add 2 to both sides )

x = 9
