If lines a and b are parallel determine the value of x.
==================================================
Work Shown:
If line a is parallel to line b, then the alternate interior angles (4x-30) and (2x) are equal to one another.
Let's solve for x
4x-30 = 2x
4x-2x = 30
2x = 30
x = 30/2
x = 15

substitute this equation x+3y=18 & -x-4y=-25
Answer:
{x,y} = {3/7,-43/7}
Step-by-step explanation:
System of Linear Equations entered :
[1] x + 3y = -18
[2] -x + 4y = -25
Graphic Representation of the Equations :
3y + x = -18 4y - x = -25
Solve by Substitution :
// Solve equation [1] for the variable x
[1] x = -3y - 18
// Plug this in for variable x in equation [2]
[2] -(-3y-18) + 4y = -25
[2] 7y = -43
// Solve equation [2] for the variable y
[2] 7y = - 43
[2] y = - 43/7
// By now we know this much :
x = -3y-18
y = -43/7
// Use the y value to solve for x
x = -3(-43/7)-18 = 3/7
Solution :
{x,y} = {3/7,-43/7}

Rizwana borrowed 4500 for three years with simple interest of 7 ½% per annum. How much did she repay?
Answer: 1012.50
Step-by-step explanation:
The formula for calculating Simple interest is:
= Principal × Rate × Time
= 4500 × 7 1/2% × 3
= 4500 × 7.5/100 × 3
= 4500 × 0.075 × 3
= 1012.50
Therefore, the simple interest is 1012.50
For the following right triangle, find the side length x. Round your answer to the nearest hundredth.

13
Answer:
8.31
Step-by-step explanation:
By Pythagoras Theorem,
(10)² + x² = (13)²
=> x² = (13)² - (10)²
=> x² = 169 - 100
=> x² = 69
=> x = [tex]\sqrt{69}[/tex]
=> x ≈ 8.31

A cylinder has a volume of 48 cubic cm. What is the volume of a cone with the same radius and height?
Answer:
16 cm^3
Step-by-step explanation:
The computation of the volume of a cone is shown below:
As we know that
The Volume of the cylinder is πr^h
And the volume of the cone is 1 ÷ 3 πr^h
Also the height and the radius is the same for both
so, the volume of the cone is
= 1 ÷ 3 × 48
= 16 cm^3

i need help with geometry!
Step-by-step explanation:
If m is parallel to n and one of its angle is 25
Therefore, the vertically opposite angle to angle of 25 is also equal to 25
Now, we have to find x
Therefore, x=180-25 ( interer angles on the same side of the transversal so addition of both angles is 180)
Therefore, x =155

How to expand this binomial?
Answer:
[tex] {y}^{8} + 8 {y}^{7} + 28 {y}^{6} + 56 {y}^{5} + 70 {y}^{4} + 56 {y}^{3} + 28 {y}^{2} + 8y + 1[/tex]
Answer:
Step-by-step explanation:
This is an ugly binomial expansion, which you should try to remember
These are the coefficients for the power
1,2,1 for power two
1,3,3,1 for p=3
1,4,6,4,1 for p=4
1,5,10,10,5,1 for p=5
you should see a pattern here :)

In general the terms are ordered for the expansion of (a+b) that has the form
a^n(b^0)+a^(n-1)b^1+...a^0(b^n) since we have (y+1)^8 we wind up with

What is the exact value of sec 0 in simplest form with a rational denominator?
Answer:
Step-by-step explanation:
Don't use 0 as a substitute for θ. 0 is always 0.
cosθ = -5/(2√15)
secθ = 1/cosθ = -2√15/5
The exact value of sec θ is -8.6/5.
What is Trigonometry?One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.
We have,
Point(-5, -7).
Here, x= -5 and y= -7
So, r = √x² + y²
r= √(-5)² + (-7)²
r= √25 + 49
r = √74
r= 8.6
So, sec θ= H/ B
= r/x
= 8.6/ (-5)
= -8.6/ 5

Find the circumference of the circle. Use as part of the answer
Answer:
21.99115 ≈ 22 cm
Step-by-step explanation:
1) So basically in the problem, they give you 7 cm as the diameter.
2) The circumference formula is C = 2πr (if they give you a radius) or C = πd (In this case, this would be the formula to use.)
3) Plug in; C = π(7) = 21.99114858 ≈ 22 cm
