How would you find the two triangles are similar?
Answer:
The answer should be A.
Step-by-step explanation:
Well, to determine how two triangles are similar you first look at the image of what they give you.
As you can see the images shows only degree angles.
Looking at your option to see degree angles.
In some options, there is a side length of a triangle, but we aren't given a side length on both triangles so that answer does that apply.
Our last option is between A and D.
D is false as we determine the triangles are similar to each other.
RCW and VCB are vertically opposite meaning their 25° are the same to each other.
We know that every triangle adds up to 180.

The graph of r = -10 cos θ has which of the following characteristics?
Answer choices are listed below.
Step-by-step explanation:
If we convert
[tex]r = - 10 \cos(x) [/tex]
to a Cartesian equation,
[tex] {r}^{2} = - 10 r \: \cos(x) [/tex]
[tex] {x}^{2} + {y}^{2} = - 10x[/tex]
[tex] {x}^{2} + 10x + {y}^{2} = 0[/tex]
[tex] {x}^{2} + 10x + 25 + {y}^{2} = 25[/tex]
[tex](x + 5) {}^{2} + {y}^{2} = 25[/tex]
So we have a circle with center (-5,0), with a diameter of 10.
What is the area of the figure below?
Answer:
B. 33cm^2
Step-by-step explanation:
To calculate the area of a figure, you'll need to multiply the base times the height.
So, you calculate the area of the two figures and you add them up.
(4x2) + (5x5) = 33cm^2
Answer:
The answer is B. 33 cm^2
Step-by-step explanation:
Area Formula of Square/Rectangle: Area = Length * Width
Left Box:
Area = Length * Width
Area = 4 cm * 2 cm = 8 cm^2
Right Box:
Area = Length * Width
Area = 5 cm * 5 cm = 25 cm^2
Total Area = 8 cm^2 + 25 cm^2 = 33 cm^2
prove that y=2x^2-6x+7 and y=x^2-2x+3 touch each other and find the point of contact
Answer:
See below ~
Step-by-step explanation:
We need to prove they are equal.
Equate the values to each other.
2x² - 6x + 7 = x² - 2x + 3x² - 4x + 4 = 0(x - 2)² = 0x = 2Now input the x-value in the 1st equation.
y = 2(2)² - 6(2) + 7y = 8 - 12 + 7y = -4 + 7y = 3Now input the same in the 2nd equation.
y = (2)² - 2(2) + 3y = 4 - 4 + 3y = 3Since the same x-value, on inputting in both equations, give the same y-value, it is proved they touch each other.
Point of Contact

Answer:
C. 15800 to spare
Step-by-step explanation:
All you have to do is add up the total money he has to spend money, then you add up the total cost, and subtract the total money he has to spend by the total cost, and you're left with he has 15,800 left to spare. ;)
He should make a loan from the investors about 4.6%..
What is Percentage?To determine the volume or chance of commodity in terms of 100, use the chance formula. Per cent simply means one in a hundred. With the chance formula, a number between 0 and 1 can be expressed. A number that's expressed as a bit of 100 is what it is. It's substantially used to compare and determine rates and is represented by the symbol.
Total quantum plutocrat Korey have
= Saving plutocrat heritage plutocrat
= $,500$,000
= $,500
Total quantum of charges
= Store Fixtures amount + Computer and Cash Register amount + Inventory amount +Rent amount + Insurance amount
= $2700 + $1200 + $17400 +$10800 + $3000
= $35100
So, Fund taken through loans and investor
= Total quantum of charges -Total quantum plutocrat Korey have
= $ 35100-$ 33500
= $ 1600
and, the percentage is
= 1600 x 100 / 35100
= 4.6%
He should make a loan from the investors about 4.6%.

What is the equation of a line in general form that does not have a y-intercept and goes through the point (3,6) ?
(** I know the answer is x-3 = 0, please EXPLAIN)
Answer:
[tex]x = 3[/tex]
Step-by-step explanation:
Step 1: Determine the equation
So we know that our equation does not have a y-intercept which means that it doesn't intersect ANYWHERE on the y-axis. Therefore, this means that our equation will be a straight vertical line that doesn't move side to side and just goes straight up and down. We also know that our point is (3, 6) which means that our x-value will be 3 and this is where the equation will be located.
There are several ways to display our answer where x = 3 is the most common way which basically means give me all of the y-values for the same x value of 3. Another way of saying it is x - 3 = 0 which either way when adding 3 to both sides gives you x = 3 which is what I usually go with.
Answer: [tex]x = 3[/tex]
Answer:
x = 3 or x - 3 = 0
Step-by-step explanation:
Given
It does not have a y-interceptPasses through the point (3, 6)Solving
If the line cannot touch the y-axis, it has to be parallel to it (in other words, the line must be vertical)Since the x-value is constant for a vertical line and it passes through the point (3, 6), the equation of the line will be :x = 3 or x - 3 = 0Find the value of the trigonometric ratio.

20) What fraction of the square is shaded if the line inside divides the square into two equal parts?
please help me fast please
Answer:
3/8 of the area is shaded
Step-by-step explanation:
this can be determined by deviding the total shape into parts and determining those parts
so we see the top right 1/4 of the shape has a square that is shaded, with the triangle only covering 1/2 of this shape becuase the hypotenuse ((diagnal edge of a right triangle)) devides the square in half
beings that 1/2 of the 1/4 square is shaded, we know that in reation to the whole shape that the small shaded area is equal to 1/8 ((1/2 ÷ 1/4 = 1/8))
same can be said for the bottum shape, with the bottum half of the whole shape half covered we can determine its total shaded area in relation to the shape ((1/2 ÷ 1/2 = 1/4))
the left top shape is completely unshaded so we wont need to calculate any shadded area into the equation
with the total shape covered by 1/4 + 1/8 we can find the least common denominator between the two fractions to get a simplifide answer for the total shaded area
1/4 = 2/8
2/8 + 1/8 = 3/8
this leaves 5/8 of the shape unshaded
3/8 fraction of the square is to be shaded.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
In the top right 1/4 of the shape has a square that is shaded, with the triangle only covering 1/2 of this shape because the hypotenuse divides the square in half.
1/2 of the 1/4 square is shaded, we know that in relation to the whole shape that the small shaded area is equal to 1/8.
same can be said for the bottom shape, with the bottom half of the whole shape half covered we can determine its total shaded area in relation to the shape.
1/4 = 2/8
2/8 + 1/8 = 3/8
Hence, 3/8 fraction of the square is to be shaded.

A store buys a remote control robot for $60. They mark it up by 30%. What will be the selling price
Step-by-step explanation:
The store buys a remote control robot for $60 plus it marks up by 30%.
First, we need to convert 30% to a decimal of 0.30.
Then we multiply 60 by 0.30.
60*0.30=18
We know we have to add the original price of $60 with an $18 markup.
60+18=78
We now get $78 as the selling price.

sum of three number= 98
to find:the second number.
solution:Let the three numbers be x, y and z
Sum of the numbers is 98.
x + y + z = 98………………(i)
The ratio of the first to the second is 2/3.
x/y = 2/3
x= 2/3 × y
x= 2y/3
The ratio of the second to the third is 5/8.
y/z= 5/8
z/y= 8/5
z= 8/5 × y
z= 8y/5
Put the value of x = 2y/3 and z = 8y/5 in (i).
2y/3 + y + 8y/5= 98
49y/15= 98
49y= 98 × 15
49y= 1470
y= 1470/49
y= 30
Therefore, the second number is 30.
