Answer:
A= 560mph, B=5,600miles in 10 hours
Step-by-step explanation:
If you divide 3,360 by 6 to get the mph for part a, you’ll then multiply that by 10 to get part b.
3,360 / 6= 560
560*10=5,600

What are congruence triangles?If pairings of corresponding sides and corresponding angles are equal, two triangles are said to be congruent. They are the exact same size and form.
Consider triangles SQT and SRQ
Angle RSQ = Angle QST
Angle SRQ = Angle STQ (90 degrees)
side SQ = side SQ (common)
By Angle Angle Side (AAS) property , both triangles are congruent.
Thus, Side RQ = Side QT
Substitute the values,
3x + 12 = 4x - 8
4x - 3x = 12 + 8
x = 20
Put x =20 in RQ
RQ = 3x + 12
= 3×20 + 12
RQ = 72
Therefore, the Side of Triangle RQ = 72 units.

Darlene is buying a cake for her parent’s anniversary party. She has two to choose from. The cakes are similar prisms.
What is the ratio of the volumes of the smaller cake to the larger cake?
Select the correct response:
A. 8:27
B: 16:81
Ratio of the volumes of the smaller cake to the larger cake is A: 8 : 27.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given are two cakes in the form of a rectangular prism.
Volume of the rectangular prism = Length × Width × Height
Volume of the smaller cake = 12 × 8 × 2
= 192 inches³
Volume of the larger cake = 18 × 12 × 3
= 648 inches³
Ratio of volumes = 192 / 648
= 24 / 81 [Dividing by 8]
= 8 / 27 [Dividing by 3]
Hence the required ratio is 8 : 27.

What is 3+0.75x=5.25-0.25 equal?
3 + 0.75x = 5.25 - 0.25x
0.75x = 2.25 - 0.25x
x = 2.25
3 + 0.75(2.25) = 5.25 - 0.25(2.25)
3 + 1.6875 = 5.25 - 0.5625
4.6875 = 4.6875

The rides at an amusement park have restrictions based on height. For the Swan Ride, the minimum height is 2 feet and the maximum height is 3 feet. Write and solve an absolute value equation that has these minimum and maximum heights as its solutions.
Answer:
11 feet
Step-by-step explanation:
The solution for the absolute value equation is height = 2.5 feet, which lies between the minimum and maximum height restrictions of 2 feet and 3 feet for the Swan Ride.
We have,
The absolute value equation representing the height restrictions for the Swan Ride would be:
| h - 2 | = 3 - h
To solve this equation:
Solving this equation gives:
For height - 2 ≥ 0:
height - 2 = height - 3
-2 = -3 (no solution in this case)
For height - 2 < 0:
-(height - 2) = height - 3
-height + 2 = height - 3
2 + 3 = height + height
5 = 2 * height
height = 5 / 2
height = 2.5 feet
Thus,
The solution for the absolute value equation is height = 2.5 feet, which lies between the minimum and maximum height restrictions of 2 feet and 3 feet for the Swan Ride.

Answer fast please.
[tex] \sf{ \red{ \underline{Solution - }}} \\ [/tex]
Given equation is 1/(x+2) - 1/(x-2) = 1
=> [(x-2)-(x+2)]/(x+2)(x-2) = 1
=> (x-2-x-2)/(x²-4) = 1
=> (-2-2)/(x²-4) = 1
=> -4/(x²-4) = 1
=> x²-4 = -4
=> x²-4+4 = 0
=> x² +0 = 0
=> x² = 0
The standard form is x² = 0 or x²+0x+0 = 0
Here I have used this formulae in your all questions.
The standard quadratic equation is ax²+bx+c = 0

59°
A. isosceles
B. equilateral
C. neither
Answer:
Neither
Step-by-step explanation:
180-59-61 = 60 degrees
It is an scalene triangle = no equal angles
Step-by-step explanation:
option C is correct ( neither).
because the other side is 180-61-59 = 60.
therefore, the three angles are different, and it's a scalene triangle.

Answer:
C
Step-by-step explanation:
Can't be B or D because the slope is negative but B and D have positive slopes. It's not A because slope is y2-y1/x2-x1. Take points (0,8) and (6,5) to plug into equation.
5-8/6-0= -3/6=-1/2
Therefore the answer is C since the y-intercept is 8 and the slope is -1/2
