Answer: 33 mph
Step-by-step explanation:
First find out what 40% of 55 is:
= 40% * 55
= 22 mph
This means that the speed reduces by 22 mph inside the city.
The speed inside the city is therefore:
= 55 - 22
= 33 mph

Tell whether the ratios form a proportion
2: 8/3 and 2/3: 6
Answer:
no
Step-by-step explanation:
you can cross-multiply and see if you get the same products
(2/1 ÷ 8/3) / (2/3 ÷ 6/1)
2/1 · 6/1 ≠ 8/3 · 2/3
12 ≠ 16/9

12 feet = meters
Answer:
3.7 metres
Step-by-step explanation:
1 foot = 0.305 metre
12 foot = 12 × 0.305
= 3.6576
Rounding the answer to nearest hundredth
3.6576 = 3.7000
= 3.7 metres

Way to do#since the x inside (x) change into (5), then just change the x with (5)
f(x) = 3x + 2
f(5) = 3(5) + 2

Triangle ABC is rotated 45 digress counterclockwise about vertex A to obtain triangle XYZ. If the m
8n - 2(n+5) = -3 + 6n
Answer:
No solution
Step-by-step explanation:
There are no values of n that make the equation true.
8n −2(n+5) = −3 + 6n
First Step: Simplify both sides of the equation
(Distribute) 8n + (-2)(n) + (-2)(5) = -3 + 62
8n + -2n + -10 = -3 + 6n
(Combine like terms) (8n + −2n) + (−10) = 6n − 3
6n + −10 = 6n − 3
6n − 10 = 6n − 3
Step 2: Subtract 6n from both sides
6n − 10 − 6n = 6n − 3 − 6n
-10 = -3
Step 3: Add 10 to both sides
-10 + 10 = -3 + 10

A cylinder has a diameter of 6 cm and a height of 14 cm. What is the approximate volume of a cone with the same diameter and height
as the cylinder?
The approximate volume of a cone with the same diameter and height as the cylinder is 131.95 cm³.
How to calculate the volume of a cylinder?In Mathematics and Geometry, the volume of a cylinder can be calculated by using this formula:
Volume of a cylinder, V = πr²h
Where:
V represents the volume of a cylinder.h represents the height of a cylinder.r represents the radius of a cylinder.Radius = diameter/2 = 6/2 = 3 cm.
By substituting the given parameters into the volume of a cylinder formula, we have the following;
Volume of cylinder, V = π × 3² × 14
Volume of cylinder, V = π × 9 × 14
Volume of cylinder, V = 395.8 cm³.
For the volume of this cone, we have:
Volume of cone, V = 1/3 × πr²h
Volume of cone, V = 1/3 × 395.8
Volume of cone, V = 131.95 cm³.

Please help me, I forgot how to do this):
Answer:
x = 8
Step-by-step explanation:
Recall that the interior angles of a triangle always add up to 180 degrees.
Therefore: 77 + 50 + 7X - 3 = 180, or:
77 + 7X - 3 = 130, or:
7x = 56
Dividing both sides by 7 yields x = 8

William left a 20% tip on a $15.80 lunch bill. How much did he pay for lunch?
Answer:
18.96
Step-by-step explanation:
15.8x120%=18.96
Answer:
the answer is 3.16 so 20 percent of 15.80 is 3.16
Step-by-step explanation:
15.80/100 = 0.158 and then 0.158 times 20 = 3.16 then 15.80 + 3.16 = 18.96 so the ANSWER IS $18.96

The length of a rectangle is 16 units more than its width. The area of the rectangle can be expressed as
x^4 – 64.
Which expression represents the width of the rectangle?
The width of the rectangle represented by the expression (x⁴ – 64)/x.
What is rectangular shape?A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle.
Given:
The length of a rectangle is 16 units more than its width.
Let the length is x units.
Then width = (x + 16) units.
The area of the rectangle can be expressed as
x⁴ – 64 = length x width
x⁴ – 64 = x (x + 16)
x + 16 =(x⁴ – 64)/x
Therefore, the width expression is (x⁴ – 64)/x.
