Answer:
r = 0
Step-by-step explanation:
slope formula is the difference of the y-values over the difference of the x-values
[r-(-3) / -4-2] = -1/2
r+3/-6 = -1/2
cross-multiply:
2(r+3) = (-1)(-6)
2r + 6 = 6
2r = 0
r = 0

The speed that a tsunami (tidal wave) can travel is modeled by the eququation where S is the speed in kilometers per hour, and d is the average depth of the water in kilometers. A tsunami is traveling at 140 km/hr. What is the approximate average depth of the water? 0.133 km 0.145 km 0.155 km
Complete question :
The speed that a tsunami can travel is modeled by the equation s = 356 StartRoot d EndRoot, where S is the speed in kilometers per hour and d is the average depth of the water in kilometers. A tsunami is traveling at 140 km/hr. What is the approximate average depth of the water? 0.133 km 0.145 km 0.155 km
Answer:
0.155 km
Step-by-step explanation:
Given the tsunami speed relation :
S = 356√d
Given a tsunami speed of 140/hr
s = 140km/hr
S = 356√d
Make d the subject
Divide both sides by 356
s / 356= √d
Hence,
140 / 356 = √d
0.3932584 = √d
Square both sides
0.3932584² = d
d = 0.1546 km
d = 0.155 km
Answer:
0.155 km

what are the coordinates of point B on AC such that the ratio of AB to BC is 2:3
The coordinates of point B on segment AC such that the ratio of AB to BC is 2 : 3 is (12 / 5, 38 / 5).
What are the coordinates of a point within a line segment?
In this problem we must use the concept of segment ratios and linear algebra operations to determine the location of a point within a line segment generated by two distinct points:
B(x, y) = A(x, y) + (AB / AC) · [C(x, y) - A(x, y)]
B(x, y) = (0, 4) + (2 / 5) · [(6, 13) - (0, 4)]
B(x, y) = (0, 4) + (2 / 5) · (6, 9)
B(x, y) = (0, 4) + (12 / 5, 18 / 5)
B(x, y) = (12 / 5, 38 / 5)
The coordinates of point B on segment AC such that the ratio of AB to BC is 2 : 3 is (12 / 5, 38 / 5).
RemarkThe statement is incomplete, complete form is shown below:

Small boxes contain DVDs, and large boxes contain one gaming machine. Three boxes of gaming machines and a box of DVDs weigh 48 pounds. Three boxes of gaming machines and five boxes of DVDs weigh 72 pounds. How much does each box weigh?
Answer:
The weight of each gaming machine be 14 pounds and that of DVD is 6 pounds.
Step-by-step explanation:
Let the weight of the gaming machine be x and that of DVD be y. ATQ,
3x+y = 48 .....(1)
3x+5y = 72 .....(2)
Subtract equation (2) from (1)
3x+y-(3x+5y) = 48 -72
y-5y = -24
-4y = -24
y = 6
Put the value of y in equation (1).
3x+6 = 48
3x = 42
x = 14
So, the weight of each gaming machine be 14 pounds and that of DVD is 6 pounds.
Answer:
DVD box weighs 6 pounds and gaming machine box weighs 14 pounds

what is the sum of the perimeter in units of the five squares in the design
Answer:
Assuming that the squares are the same size,
the sum of the perimeter of the five squares =
(20 units × side length of each square in units)
If the squares are different sizes, the sum of the perimeter of the five squares =
(4 units × side length of square 1 in units) + (4 units × side length of square 2 in units) + (4 units × side length of square 3 in units) + (4 units × side length of square 4 units) + (4 units × side length of square 5 in units)
Explanation:
The perimeter of a square is 4 × side length because a square has 4 sides and the perimeter of a figure is the surrounding length of the figure.
Determine the equation of the circle graphed below.
Answer:
(x + 5)² + (y - 1)² = 4
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (- 5, 1) and r = 2, then
(x - (- 5))² + (y - 1)² = 2² , that is
(x + 5)² + (y - 1)² = 4
Answer:
Step-by-step explanation:
hello :
hello:
note : an equatin for the circle is : (x-a)²+(y-b)²=r²
when the center is the point : C(a , b) and the radius r
use this graph : given two points in this circle A(-3,1) and B(-7,1)
1) AB/2 = r = 4/2 = 2
2) the midipoint for the segment AB is the center C
a = (-3-7)/2 and b = (1+1)/2
a= -5 and b= 1 so : C(-5 , 1)
an equation is : (x+5)²+(y-1)²=2²

Are the two triangles similar? How do you know?
Answer:
Yes, they are similar in terms of the size of their angles.
Step-by-step explanation:
The angles of a triangle always add up to 180°, so
Triangle CDE's missing angle: 180 - (60 + 53) = 67
Triangle FGH's missing angle: 180 - (67 + 60) = 53
Answer:
Yes, the triangles are similar
Step-by-step explanation:
In order for two triangles to be similar, at least two corresponding angles must be congruent.
We know DCE and GFH are congruent, because they are both 60°, so that's one angle down, now we need one more.
We can either choose to see if CDE and FGH are the same, or CED and FHG. I'll choose CDE and FGH.
We know CDE is 53°, so we need to find FGH to see if it's also 53°.
The sum of the interior angles of a triangle are 180°, so we can find FGH by doing 180-60-67=53°, so CDE and FGH are congruent.
Knowing DCE and GFH are congruent, and CDE and FGH are congruent, we can say that these triangles are similar.

Carol's car average is 17.1 miles per gallon in City driving and 24.7 miles per gallon in highway driving if she drove a total of 513.0 miles on 26 gallons of gas how many of the gallons were used for City driving
Answer:
the volume of the gas used for city driving is 17 gallons
Step-by-step explanation:
Given;
average speed for city driving, v₁ = 17.1 miles per gallon
average speed for highway driving, v₂ = 24.7 miles per gallon
total distance traveled, d = 513 miles
total gallon of gas used, t = 26 gallons
Let the volume of gas used for city driving = x
Also, let the volume used for highway driving = y
x + y = 26 -------- (1)
17.1x + 24.7y = 513 ------------(2)
From equation (1); y = 26 - x
Substitute the value of y in equation (2)
17.1x + 24.7(26-x) = 513
17.1x + 642.2 - 24.7x = 513
17.1x - 24.7x = 513 - 642.2
-7.6x = -129.2
x = 129.2/7.6
x = 17 gallons
Therefore, the volume of the gas used for city driving is 17 gallons

Convert the angle 5.5 radians to degrees, rounding to the nearest 10th.
Answer:
315.1*
Step-by-step explanation:
The value of 5.5 radians into degree is 315⁰.
What is radians?
The radian, denoted by the symbol rad, is the SI unit for measuring angles, and is the standard unit of angular measure used in many areas of mathematics.
Conversion of radian to degree = radian X 180⁰/π
Now,
Degree = 5.5 X 180⁰ X 7/22
= 6930/22
= 315⁰
Thus, the value of 5.5 radians into degree is 315⁰.

The library had 202 shelves of books. Each shelf had 14 books. Librarians checked out 907 books to students. How many books does the library have remaining? PLZ WORTH 25 POINTS
Answer:
1921 books remaining.
Step-by-step explanation:
This library is fairly organized, so each shelf only has 14 books. Now with 202 shelves, we multiple the shelves by the amount of books per shelf.
202x14=2,828
Now, with 2828 books in the library before being checked out, we need to find out how many books left after the students came.
2828-907=1,921
The answer is 1,921 books remaining.
