Which ordered pair is a solution of the equation 2x - 3y = 18?
Answers
Answer:
(3,-4)
Explanation:
The easiest way to solve this question is to use each of the given order pairs, substitute with them in the equation and check whether the equation is satisfied or not.
The given equation is:
2x - 3y = 18
1- For (0,8):
2(0) - 3(8) = -24 .....> not equal to 18 .....> wrong choice
2- For (2,5):
2(2) - 3(5) = -11 .....> not equal to 18 .....> wrong choice
3- For (3,-4):
2(3) - 3(-4) = 18 .....> equal to 18 ......> correct choice
4- For (6,2):
2(6) - 3(2) = 6 .....> not equal to 18 ......> wrong choice
Based on the above, the correct choice is (3,-4)

Find the area of the triangle. (round to the nearest whole number)
Answers
============================================================
Explanation:
Check out the attached image. I've added in points A through D. The points A,B,C are the vertices of the largest triangle. Point D is directly below point A, and point D is on segment BC.
To find the area of the largest triangle ABC, we need the base length BC, which is broken up into segments x and y
x = length from C to D
y = length from D to B
Let's find x first
Triangle ADC is a right triangle, so we can use the pythagorean theorem
a^2 + b^2 = c^2
x^2 + 15^2 = 17^2
x^2 + 225 = 289
x^2 = 289 - 225
x^2 = 64
x = sqrt(64)
x = 8
Follow similar steps to find y
a^2 + b^2 = c^2
y^2 + 15^2 = 25^2
y^2 + 225 = 625
y^2 = 625 - 225
y^2 = 400
y = sqrt(400)
y = 20
Therefore
BC = x+y
BC = 8+20
BC = 28
The base of the triangle ABC is BC = 28 units
b = base
b = 28
The height is AD = 15
h = height
h = 15
We can now find the area of triangle ABC
Area = b*h/2
Area = 28*15/2
Area = 420/2
Area = 210
The area of the triangle is 210 square inches

Answers
Answer:
Rotate clockwise around right most point.
Step-by-step explanation:
We are given that,
The room has an oil stain as shown in the graph.
It is required to rotate the kite figure to fully cover the stain.
So, we get,
If we rotate the figure clockwise, it will completely cover the stain.
Moreover, the figure should be rotated around the right most point clockwise, which will become the center of rotation.
Describe the type of angles formed when you divide a circle into 4 equal parts
Answers
when a circle is divided into four equal parts, we will get 4 right angles
so

When we divide a circle into 4 equal parts, the angles formed are the right angles.
When a circle is divided into 4 equal parts, we get 4 quarters of the circle.
What is a quarter of a circle?The area that is intercepted by two radii that are at 90° to each other and a quarter portion of the circumference of a circle is known as a quarter circle.
In a quarter of a circle, the angle between radii is 90 degrees.
So, When we divide a circle into 4 equal parts, the angles formed are the right angles.
Hence, When we divide a circle into 4 equal parts, the angles formed are the right angles.

What is the total number of outcomes in the sample space for Tossing a coin and spinning a spinner with 5 equal sections
Answers
because a coin has two sides ( heads or tails) then the spinner is 5 equal sections so 2/5 <3
hope it helps
There are 10 possible outcomes in the sample space when tossing a coin and spinning a spinner with 5 equal sections.
When tossing a coin and spinning a spinner with 5 equal sections, the total number of outcomes in the sample space can be calculated by multiplying the number of outcomes for each event.
For the coin toss, there are 2 possible outcomes: heads (H) or tails (T).
For spinning the spinner, there are 5 possible outcomes: each of the 5 sections.
So, the total number of outcomes in the sample space is the product of these two numbers:2×5=10.
Complete question :
What is the total number of outcomes in the sample space for Tossing a coin and spinning a spinner with 5 equal sections?

find the value of sin2a, if tana=-12/5 in the fourth quadrant
Answers
Recall the following identities:
[tex]1+\tan^2a=\sec^2a=\dfrac1{\cos^2a}[/tex]
[tex]\cos^2a=\dfrac{1+\cos2a}a[/tex]
from which we get
[tex]1+\left(-\dfrac{12}5\right)^2=\dfrac1{\cos^2a}[/tex]
[tex]\implies\cos^2a=\dfrac{25}{169}[/tex]
Since [tex]a[/tex] is in the fourth quadrant [tex]\left(\dfrac{3\pi}2<a<2\pi\right)[/tex] we know that [tex]\cos a[/tex] should be positive, so when we take the square root here, we should take the positive root.
[tex]\implies\cos a=\sqrt{\dfrac{25}{169}}=\dfrac5{13}[/tex]
Now recall that
[tex]\cos^2a+\sin^2a=1[/tex]
and since [tex]a[/tex] is in the fourth quadrant, we expect [tex]\sin a[/tex] to be negative. So,
[tex]\sin^2a=1-\cos^2a=\dfrac{144}{169}\implies\sin a=-\sqrt{\dfrac{144}{169}}=-\dfrac{12}{13}[/tex]
One final identity:
[tex]\sin2a=2\sin a\cos a[/tex]
from which we get
[tex]\sin2a=2\cdot\left(-\dfrac{12}{13}\right)\cdot\dfrac5{13}=-\dfrac{120}{169}[/tex]
a new parking lot is being built for a medical office. the expression representing the number of parking spots in the new lot is 15x/4-9 where x represents the number of parking lots in the first row. how many spots are in the parking lot if there are 32 parking spots in the first row?
Answers
Answer:
The number of spots in the parking lot if there are 32 parking spots in the first row =111.
Step-by-step explanation:
We are given that a new parking lot is being built for a medical office.
We are given that
The expression representing the number of parking spots in the new lot =[tex]\frac{15x}{4}-9[/tex]
Where x= The number of parking lots in the first row
We have to find number of spots in the parking lot when parking spots in the first row is 32.
The number of parking spots in the first row =x=32
Substitute the value of x in the given expression then we get
Number of spots in the parking lot =[tex]\frac{15\times 32}{4}-9[/tex]
Number of spots in the parking lot=[tex]\frac{480}{4}-9[/tex]
The number of spots in the parking lot=120-9
The number of spots in the parking lot=111.
Hence, the number of spots in the parking lot if there are 32 parking spots in the first row=111.

solve for x please!!!!
Answers
11) Since the triangle has a pair of congruent base angles, it is an isosceles triangle which means that the two pairs of legs are congruent.
Make them equal to each other in an equation.
5x = x + 20
Subtract x from both sides.
4x = 20
Divide both sides by 4.
x = 5
12) The two legs are congruent so that means the base angles must be congruent. First find the measure of the base angles. Create an equation:
x + x + 50 = 180
Combine like terms.
2x + 50 = 180
Subtract 50 from both sides.
2x = 130
Divide both sides by 2.
x = 65
Now make the base angle plus x equal 180, because they form a straight line.
65 + x = 180
Subtract 65 from both sides.
x = 115
13) You know the vertex angle (top angle) is 90 degrees because it is supplementary to a right angle. The triangle is isosceles because the two legs are congruent, so make the base angles plus 90 add up to 180 in an equation.
x + x + 90 = 180
Combine like terms.
2x + 90 = 180
Subtract 90 from both sides.
2x = 90
Divide both sides by 2.
x = 45
