James is reading a book and noticed the page numbers are consecutive integers whose product is 1640. What is the value of the larger page number?
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:
7. <B = 129°8. <N = 85°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)

consider the equation a(4-x) =-3x + b What values of a and b make the solution of the equation x = -5
Answer:
Step-by-step explanation:
hello :
put x = -5 in this equation : a(4-x) =-3x + b
a(4+5) =15 + b
9a = 15 +b
b = 9a - 15
the values of a and b is all order pair : ( a ; 9a-15) a real number
How to find the missing dimensions of a prism
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

The worlds largest flower, the Rafflesia, has a circumference of 286 centimeters. Find the approximate diameter of the flower. Use 3.14 for pie. Round to the nearest hundredth if necessary.
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.

If cosec theta-cot theta is equal to 1/M then what is the value of cosec theta +cot theta
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].

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:
m(n + p) = mn + mp
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]
Answer: 6w - 10y

Slope= -7/4
Y-intercept= 5
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

What would the missing value be?
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
