Answer:
slope = 20
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (10, 200) ← 2 points on the line
m = [tex]\frac{200-0}{10-0}[/tex] = [tex]\frac{200}{10}[/tex] = 20

Someone please help me out!!
Answer:
D 3/4
Step-by-step explanation:
imagine a circle with its center in point A and going through point C.
the radius of that circle is 50 (AC).
remember, tan of an angle is sin/cos of that angle.
now rotate in our imagination that triangle to the right around point A, so that the side AB becomes the bottom base line.
now you see that 30 = sin(A)×radius = sin(A)×50
and 40 = cos(A)×radius = cos(A)×50
so, tan(A) = (sin(A)×50)/(cos(A)×50) = sin(A)/cos(A) = 30/40
= 3/4

Which similarity statement expresses the relationship between the two triangles?
triagleZYX- triangleCAB
triangleZYX-triangleACB
triangleZYX-triangleCBA
triangleZYX - triangleABC
Given:
The figure of two triangles.
To find:
The similarity statement for the given triangles.
Solution:
The corresponding sides of similar triangles are proportional.
In the given triangles,
[tex]\dfrac{XY}{AB}=\dfrac{6}{12}[/tex]
[tex]\dfrac{XY}{AB}=0.5[/tex]
Similarly,
[tex]\dfrac{YZ}{BC}=\dfrac{3}{6}[/tex]
[tex]\dfrac{YZ}{BC}=0.5[/tex]
And,
[tex]\dfrac{XZ}{AC}=\dfrac{7}{14}[/tex]
[tex]\dfrac{XZ}{AC}=0.5[/tex]
Since [tex]\dfrac{XY}{AB}=\dfrac{YZ}{BC}=\dfrac{XZ}{AC}[/tex], therefore
[tex]\Delta XYZ\sim \Delta ABC[/tex]
It can be written as:
[tex]\Delta ZYX\sim \Delta CBA[/tex]
Therefore, the correct option is A.

A water slides at a party of s 15 feet tall.The base of the water slide is 8 feet long.what is the length of the slide?
Answer:
It would be 17 feet.
Step-by-step explanation:
So to do this, there is a right triangle being made with the height of the water slide and its base (length). With this, the Pythagorean Theorem can be used to find the hypotenuse of these lengths by the equation:
a^2 + b^2 = c^2
So by plugging in the given legs of the triangle, the answer can be found.
15^2 + 8^2 = c^2
225 + 64 = c^2
289 = c^2
c = 17
Item 19 Your pump empties the water from a swimming pool in 6 hours. When your friend's pump is used together with your pump, the pool is emptied in 1.5 hours. How long (in hours) does it take your friend's pump to empty the pool when working alone
Answer:
0.75 hours
Step-by-step explanation:
Time taken by my pump = 6 hours
Time taken by friend's pump = x
Combined time = 1.5 hours
Rate :
my pump = 1/6
Combined rate = 1/1.5
Combinwd rate = 1/6 + 1/x
Hence :
1/6 + 1/x = 1/1.5
(x + 6) / 6x = 1.5
x + 6 = 9x
x - 9x = - 6
-8x = - 6
x = - 6 / - 8
x = 0.75 hours
A calculator costs $85 at staples if the calculator is 20% off how much do you pay?
Answer:
$ 17 off
Step-by-step explanation:
20% is one fifth of the price
So divide 85 by 5 you get 17
Since you only get one 1/5 of the price off you save $17
Just to check and make sure you can do 17 * 5 = 85

A car dealership offers two types of discounts.
Discount 1: Take 5% off the original price of a car built last year, and then receive a $3,500 rebate.
Discount 2: Take 10% off the original price of a car built this year, and then rece ve a $1,250 rebate.
A customer is deciding between two cars. Car R was bure ast year and has an original price of $25,340. Car 5 was built this vear and has an original price of 522.960. .
Based on this information, which statement is true?
F The customer would pay $19,524 for cars S.
G The customer would pay $24.078 For Cars R.
H The customer would pay $21,824 For Cars S.
J The customer wou d pay $23.10 O Car R.
Question:
Based on the same question options as found an online resource, we have;
Statement
G. The customer would pay $24,073 for car R
Answer:
The true statement
G. The customer would pay $24,073 for car R
Step-by-step explanation:
Discounts are deductions from the original price of a commodity or service
A rebate is a partial refund after payment is made
The discount offered by the car dealership are;
Discount 1;
5% reduction off a car built last year's original price, + $3,500 rebate
Discount 2;
10% reduction off a car built this year's original price + $1,250 rebate
The year car R was built = Last year
The original price for car R = $25,340
Let 'A' represent the amount the customer would pay, let, 'p' represent the price of the car, let 'd' represent the discount offered, and let 'r' represent the rebate
Given that the payment is made before the rebate, we have;
The amount the customer will pay, A = p - (p×d)
Therefore;
The amount the customer would pay for car R = $25,340 - (0.05 × $25,340) = $24,073
The amount the customer would pay for car S = $22,960 - (0.1 × $22,960) = $20,644
Therefore, the true statement, is the customer would pay $24,073
Answer:
$24,073

The value of an investment after t years is given by the function, A (t) = 500 (1 + 0.07t).
Complete the following statement. The initial value of the investment is_____,and the annual simple interest rate is____percent.
For the first blank
A. $500
B. $700
For the second blank
A.50
B.70
C.7
D.0.5
E.0.07
Answer:
A. $500
C. 7 percent
Step-by-step explanation:
Your problem follows the format of the Simple Interest Formula.
The formula is described as follows: A = P(1 + r*t)
Where P = initial value
r = interest rate as a decimal
t = amount of time.
In your equation of A = 500 ( 1 + 0.07 t )
we can see that 500 represents the P value which is the initial value of the investment.
We can also see that the rate is 0.07. Then converted from a decimal to a percent would be 7 percent.

X
オー2
x + 5
x + ]
A
7.5
B.
10
C
2.5
D
5
Answer:
D 5
Step-by-step explanation:
the same scaling factor s applies to all sides when transforming from the small to the large triangle.
x×s = x + 5
(x-2)×s = x +1
=> s = (x+5)/x
=> (x-2)×(x+5)/x = x + 1
=> x² + 3x - 10 = x² + x
=> 3x - 10 = x
=> 2x = 10
=> x = 5
A cylinder has a height of 8 inches and a radius of 7 inches. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth. Cubic inches
Answer:
No idea, just wanna learn and get points
Answer: [tex]1230.88\ in.^3[/tex]
Step-by-step explanation:
Given
A cylinder has a height [tex]h=8\ in.[/tex]
Radius of the cylinder is [tex]r=7\ in.[/tex]
Volume of the cylinder is given by [tex]V=\pi r^2 h[/tex]
Insert the values
[tex]\Rightarrow V=\pi \times 7^2\times 8\\\Rightarrow V=3.14\times 49\times 8\\\Rightarrow V=1230.88\ in.^3[/tex]
Thus, the volume of the cylinder is [tex]1230.88\ in.^3[/tex]

Mr. Falk is going to replace the carpet in his basement. The basement is
rectangular with a length of 27 feet and a width of 18 feet. If the cost of the
carpet is $32 per square yard, what will be the total cost?*
==========================================================
Explanation:
1 yard = 3 feet
We'll divide by 3 to convert from feet to yards
27 feet = 27/3 = 9 yards18 feet = 18/3 = 6 yardsThe basement is 9*6 = 54 square yards in floor area.
At $32 per square yard, the total cost to carpet the floor is 32*54 = 1728 dollars.
A tiene la mitad de lo que tiene B. Si A gana 66 y B pierde 90. A tendrá del doble de lo que le quede a B ¿cuanto tiene cada uno?
Respuesta:
a = 82; b 164
Explicación paso a paso:
a = 1 / 2b - - - (1)
a gana 66 = a + 66
b = b - 90
a = 2b
a + 66 = 2 (segundo - 90) - - - (2)
Ponga a = 1 / 2b en (2)
1 / 2b + 66 = 2 (b-90)
0.5b + 66 = 2b - 180
0.5b - 2b = - 180 - 66
-1,5b = - 246
b = 164
a = 1 / 2b
a = 1/2 * 164
a = 82
