Answer:
4. x=120
5. x=65
9. x=150
10. x=45
Step-by-step explanation:
4. Half=180
There is already a 60, so you do 180-60=120. x=120.
5. This is a parallel line, so you determine the opposite angle of 115, which is 65. That just becomes the x. x=65
9. It is similar to #5, You look at the opposite side of 30 (15+15) which is 150. That just comes to the other side which is x=150.
10. A triangle has 180 degrees in total. 45 degrees is already given, and line j is 90 degrees which means a full line is 180. 180-90=90.
90+45=135
180-135=45
x=45

Anton bought a picnic cooler. His total bill, with tax, was $7.95.
He paid 6 percent sales tax. How much did he pay for the cooler
alone without the tax?
Answers
Answer:
$ 7.50
Step-by-step explanation:
The cost of the picnic cooler would be 100%.
With the 6% sales tax, Anton would pay 106% of the cost if the picnic cooler.
(since 100% +6%= 106%)
106%(picnic cooler)= $7.95
Cost of picnic cooler= 100%(picnic cooler).
Cost of picnic cooler

From the figure the correct options are ΔABC ~ ΔDEC, ∠B ≅ ∠E, 3DE = 2AB.
Given that a right triangle ΔABC is being dilated by a scale factor of 2/3 and reflected over the side AC to form the ΔDEF.
Since we know that in reflection transformations the object are similar so we can conclude that ΔABC ~ ΔDEC.
Also, by the definition of similar triangles,
∠B ≅ ∠E, ∠A ≅ ∠D and ∠ACB ≅ ∠DCE.
Now since the scale factor is 2/3,
so,
2AB = 3DE
2BC = 3CE
2AC = 3DC
Hence the correct options are ΔABC ~ ΔDEC, ∠B ≅ ∠E, 3DE = 2AB.

Answers
Answer:
13 inches
Step-by-step explanation:
Draw a square and draw a diagonal line through it. It creates a right triangle. So we can then use the Pythagoras theorem to find the length of the object at it's max. so we do a^2+b^2=c^2. So we do (12*12) + (5*5) = 169 and the square root of 169 is 13.

Answers
Answer:

Step-by-step explanation:
Add these two side lengths together. We get 37. Unless the 3rd side is LESS than 37, we cannot form a triangle.
Next, subtract 15 from 22, obtaining 7. The 3rd side has to be GREATER than 7 in order for the sides 7+, 15 and 22 to form a triangle.

The graph shows a journey in a car. Which of the statements most likely describes the journey back to the starting point at the the portion of the graph labeled O?
Answers
Answer:
The car travels different distance per unit of time.
Step-by-step explanation:
Distance per unit time on graph will be = Distance for a given point time/ Time
if we see this in terms of x and y , it will be the slope of the curve on given graph.
y/x = slope of graph
Now solving it becomes easier.
We know that
slope = [tex]tan\alpha[/tex] where [tex]\alpha[/tex] is the positive angle with x axis
For part I
The slope will be tan of some acute angle and we know that
tan of acute angle varies between 0 to 1.
Distance per unit time on graph will be between 0 to 1
for part J
Line is parallel to x axis and hence angle with x axis will be 0
thus,
tan 0 = 0
slope of part j is 0
Distance per unit time on graph will be = 0
For part k the distance is changing at each point hence we have to find
distance for each point and time for each point on coordinate and hence
Distance per unit time on graph for part k will be different at each point.
part L and N can be explained on similar grounds as J
O can be explained by explanation for part K.
Part M can be explained by explanation of part I
here difference will be that slope is obtuse and hence
slope or distance per unit time will be negative
as tan for obtuse angle is between -1 to 0.
Thus, correct option will be
The car travels different distance per unit of time.

Answers
Let’s see if I can help you :)!
With two points you can define a line.
So, the line parallel to s is q, which has these two pointS: (3,6) and (6,3)
There are different ways to get the line. For instance, this one:
Y = a*x+b
a = slope = difference_y/difference_x = (3-6)/(6-3) = -1,
y = -x + b,
Now use any point, say (3,6) to get b:
6 = -3+b-> b - 9.
Line is y = -x + 9,
It checks out in the other point: (6,3) —> 3 = -6+9 = 3. Good.
Other method:
y-y2 = a*(x-x2), where (x2,y2) is one of the two points and a is the slope as defined before.

10) A rectangular patio measures 3x+4 meters by
2x-1 metres. If the perimeter of the patio measures 96
meters. Find the area of the patio.
Answers
This problem requires multiple steps, so please read through the whole answer to get a good understanding on how to solve this problem
Step 1: Create an equation for the perimeter respect to x
The equation for the perimeter p is:
[tex]p=2w+2l[/tex] where w is the width and l is the length
The length is 3x+4 and the width is 2x-1, so substitute these values into the equation:
[tex]p=2(3x+4)+2(2x-1)[/tex]
[tex]=6x+8+4x-2[/tex]
[tex]=10x+6[/tex]
This is the equation for the perimeter
Step 2: Solve for x since we are given the perimeter
We are given that the perimeter is 96, thus we can create the equation:
[tex]10x+6=96[/tex]
Subtract 6 from both sides
[tex]10x=90[/tex]
Divide both sides by 10
[tex]x=9[/tex]
We have now found the value of x
Step 3: Find the length and width now that we know x
Plug the value of x into the expressions for the length and the width that we are given
[tex]\text{Length}=3x+4=3(9)+4=31[/tex]
[tex]\text{Width}=2x-1=2(9)-1=17[/tex]
Step 4: Solve for the area now that we know the dimensions
This is probably the easiest step. Multiply the length and width to find the area:
[tex]31 \times 17=527[/tex]
The area of the patio is 527.
I've double- and triple-checked that this is the correct answer, so do not worry about any errors.
Let me know if you need any clarifications, thanks!

What is the Volume of a Rectangle?
The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle
Volume of Rectangle = Length x Width x Height
Volume of Rectangle = Area of Rectangle x Height
Given data ,
The radius of the solid = 10 yards
The height of the solid = 6 yards
The length of the box = 4 yards
The width of the box = 4 yards
Now ,
The volume of the solid = Volume of the cylinder - Volume of box
And ,
The Volume of cylinder = π x r² x h
The Volume of box = length x width x height
So , substituting the values in the equation , we get
Volume of Cylinder = π x r² x h
= ( 22/7 ) x 10 x 10 x 6
= ( 22/7 ) x 600
= 1884.95 yards³
Volume of the box = length x width x height
= 4 x 4 x 6
= 96 yards³
Therefore ,
The volume of the solid = Volume of Cylinder - Volume of the box
The volume of the solid = 1884 yards³ - 96 yards³
= 1788 yards³
Hence , the volume of the solid is 1788 cubic yards
