The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.
Answer:
x = 348
Step-by-step explanation:
The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.
0.15x + 65 + 0.1x + 28 = 180
0.25x + 93 = 180
0.25x = 180 - 93
0.25x = 87
x = 87/0.25
x = 348

Working out shown in image above.
a line is perpendicular to y=-2x+5 and intersects the point (-4,2). what is the equation of this perpendicular line?
Answer:
y = 1/2x + 4
Step-by-step explanation:
If the line is perpendicular to y = -2x + 5 then the new line has a slope of 1/2.
So solve for b: using y = mx + b
2 = 1/2(-4) + b
2 = -2 + b
4 = b
Put it all together
y = 1/2x + 4

Find the slope of the line that passes through A(0,−5) and B(3,−4) .
Answer: 1/3
Step-by-step explanation: slope is the difference between the y values over the difference of the x values
The slope of the line that passes through A(0,−5) and B(3,−4) will be 1/3.
What is slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
The slope could be positive or negative.
The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by
Slope = (y₂ - y₁)/(x₂ - x₁)
Slope m = (-4 + 5)/(3 - 0)
m = 1/3
Hence "The slope of the line that passes through A(0,−5) and B(3,−4) will be 1/3".

that’s the problem and the answer i just need to know how to show the work. pls help me
9514 1404 393
Explanation:
The work can be done in your head, so there's really nothing to show.
If you want to go into painful detail, you can do this ...
[tex](2\sqrt{3x})(3\sqrt{6x^2})=(2\sqrt{3x})(3x\sqrt{6})=6x\sqrt{3\cdot6x}\\\\=6x\sqrt{3^2\cdot2x}=6x\cdot3\sqrt{2x}=\boxed{18x\sqrt{2x}}[/tex]
There may be some other intermediate steps you can show, or you can combine steps to the extent you think is appropriate.

7) Isidro pays $20 a month for Netflix. He also pays $0.10 for each
show he streams. Last month Isidro had a Netflix bill of $40. Write
and solve an equation to determine how many shows Isidro streamed
last month.
Answer:
200 shows
Step-by-step explanation:
subtract the total ($40) from how much he pays a month ($20) to get the total of how much he paid in shows total ($20)
40-20=20
divide the total bill of shows ($20) by how much it costs per show ($0.10) to get how many shows he has watched (200)
20/0.10=200

What are Linear Equations?An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution
On a graph, a linear equation forms a straight line. On a graph, a nonlinear equation produces an S-curve, a bell curve, or another nonlinear shape.
Given data ,
Let the linear function be represented as A
Now , the value of A is
The total cost for the SUV is given by
y₁ = 2,840x + 17,980
And , the total cost for the car is
y₂ = 3,210x + 17,980
when x = 2 years
y₁ = $ 23,660
y₂ = $ 24,400
The cost of the car is greater than cost of the SUV
Hence , the linear equations are solved

Given:
The figure of a right triangle ABC.
To find:
The trigonometric ratios [tex]\sin B, \tan A, \cos B[/tex].
Solution:
Using Pythagoras theorem,
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
[tex]AB^2=AC^2+BC^2[/tex]
[tex](10)^2=(6)^2+BC^2[/tex]
[tex]100-36=BC^2[/tex]
[tex]64=BC^2[/tex]
Taking square root on both sides.
[tex]\sqrt{64}=BC[/tex]
[tex]8=BC[/tex]
So, measure of BC is 8 units.
Now,
[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]
[tex]\sin B=\dfrac{AC}{AB}[/tex]
[tex]\sin B=\dfrac{6}{10}[/tex]
[tex]\sin B=\dfrac{3}{5}[/tex]
Similarly,
[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]
[tex]\tan A=\dfrac{AC}{BC}[/tex]
[tex]\tan A=\dfrac{6}{8}[/tex]
[tex]\tan A=\dfrac{3}{4}[/tex]
And,
[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]
[tex]\cos B=\dfrac{BC}{AB}[/tex]
[tex]\cos B=\dfrac{8}{10}[/tex]
[tex]\cos B=\dfrac{4}{5}[/tex]
Therefore, the required trigonometric ration are [tex]\sin B=\dfrac{3}{5}, \tan A=\dfrac{3}{4}, \cos B=\dfrac{4}{5}[/tex].
