On roller-skates, Ian can travel 3/4 of a mile in 5 minutes. On his bike, he can travel 3 1/2 miles in 12 minutes. How fast, in miles per hour, can Ian travel on roller skates and on his bike?
Answer:
Roller skates speed = 9 miles per hour
Bike speed = 17.5 miles per hour
Step-by-step explanation:
On roller-skates, Ian can travel 3/4 of a mile in 5 minutes.
Speed = Distance(miles)/Time(hours)
Convert 5 minutes to hour
60 minutes = 1 hour
5 minutes = 5/60
= 1/12 hour
Hence, his speed =
3/4mile ÷ 1/12
= 3/4 × 12/1
= 9 miles per hour
On his bike, he can travel 3 1/2 miles in 12 minutes.
Convert 12 minutes to hour
60 minutes = 1 hour
12 minutes = 12/60 = 1/5
Hence, his speed =
3 1/2 mile ÷ 1/5
= 7/2 ÷ 1/5
= 7/2 × 5/1
= 35/2 miles per hour
= 17.5 miles per hour

The local newspaper has letters to the editor from 80 people. If this number represents 4percent of the newspaper's readers, how many does the newspaper have?
Answer:
2000 newspaper readers
Step-by-step explanation:
Let the total number did newspaper readers the local news paper has be represented by x
Therefore,
4% of x = 80 people
Hence,
4/100 × x = 80
4x/100 = 80
Cross Multiply
4x = 100 × 80
4x = 8000
x = 8000/4
x = 2000 people
Therefore, the number of people the newspaper has is 2000 newspaper readers

Given f(x)=2^x and g(x)=f(x-3)+4, write the new function rule (equation) for function g and describe (using words*) the two transformations that occur between function f and function g.
Answer:
The first thing we do is find out what f(x-3) is[tex]f(x)=2^x\\f(x-3)=2^{x-3}[/tex] this is can be simplified using the rules of exponents[tex]f(x-3)=2^{x-3}\\f(x-3)=2^x\div2^3\\f(x-3)=\frac{2^{x}}{8}[/tex] Then we put that into g(x) [tex]g(x)=f(x-3)+4\\g(x)=\frac{2^{x}}{8}+4[/tex] The first transformation is at f(x), where it is divided by 8, and then inserted into g(x) which increases the new transformed f(x) by 4Suppose you want to prove the converse of the Pythagorean Theorem by drawing two triangles. If
one of the triangles has side lengths of m, n, and p, such that m² + n2 = pº what should
be the lengths of the sides that form a 90-degree angle in the second triangle?
А
m and n
B
m and p
С
n and p
D
p and p
Answer:
a
Step-by-step explanation:
The sides of the right angle that form 90° will be 'm' and 'n'. Then the correct option is A.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
"In the event that the square of a side is equivalent to the amount of the square of the other different sides, then triangle should be correct point triangle".
The Pythagoras theorem formula is given as
H² = P² + B²
Assume you need to demonstrate the opposite of the Pythagorean Hypothesis by drawing two triangles.
If one of the triangles has side lengths of m, n, and p, such that m² + n² = p².
Then the sides of the right angle form 90° will be 'm' and 'n'. Then the correct option is A.

Without graphing, determine whether the function represents exponential growth or exponential decay. Then find the y-intercept.
A. Exponential growth; 4
B. Exponential decay; 4
C. Exponential growth; 0
D. Exponential decay; 5
I will give brainliest to the correct answer!
Answer:
Exponential decay; 4
Step-by-step explanation:
This represents exponential decay, because the number which is being raised to the power x is less than one. This means that as x increases, y decreases.
The y-intercept occurs when x is equal to zero. When x = 0, we have [tex]y = 4(5/6)^0 = 4(1) = 4[/tex], so the y-intercept is 4.

Three friends said their heights were 5 and start fraction 13 over 30 end fraction feet, 5 and one-sixth feet, and 5 and start fraction 68 over 90 end fraction feet. Put the heights of the friends in order from least to greatest.

Answer:
[tex]5\frac{1}{6} < 5\frac{13}{30} < 5\frac{68}{90}[/tex]
Step-by-step explanation:
Represent the friends with A, B and C
[tex]A = 5\frac{13}{30}[/tex]
[tex]B = 5\frac{1}{6}[/tex]
[tex]C = 5\frac{68}{90}[/tex]
Required
Order from least to highest
First, we convert the given parameters to decimal
[tex]A = 5\frac{13}{30}[/tex]
[tex]A = 5 + \frac{13}{30}[/tex]
[tex]A = 5 + 0.43[/tex]
[tex]A = 5.43[/tex]
[tex]B = 5\frac{1}{6}[/tex]
[tex]B = 5 + \frac{1}{6}[/tex]
[tex]B = 5 + 0.17[/tex]
[tex]B = 5.17[/tex]
[tex]C = 5\frac{68}{90}[/tex]
[tex]C = 5 + \frac{68}{90}[/tex]
[tex]C = 5 + 0.76[/tex]
[tex]C = 5.76[/tex]
So, we have:
[tex]A = 5.43[/tex] [tex]B = 5.17[/tex] [tex]C = 5.76[/tex]
Order from least to greatest
[tex]B = 5.17[/tex] [tex]A = 5.43[/tex] [tex]C = 5.76[/tex]
Replace them with the original values
[tex]B = 5\frac{1}{6}[/tex] [tex]A = 5\frac{13}{30}[/tex] [tex]C = 5\frac{68}{90}[/tex]
Hence, the correct order is:
[tex]5\frac{1}{6} < 5\frac{13}{30} < 5\frac{68}{90}[/tex]

in the diagram <4 = <40 °. Find the measure of <3 = (?)°
Answer:
∠3=140°
Step-by-step explanation:
∠4 = 40°
∠3 + ∠4 = 180° (co-exterior angles are equal)
∠3 + 40° = 180°
∠3 = 180° - 40°
∠3 = 140°
[tex]or^{}[/tex]
∠2 = ∠4 = 40° (corresponding angles)
∠3 + ∠2 = 180° (linear pair)
∠3 + 40° = 180°
∠3 = 180° - 40°
∠3 = 140°

Given the function f(x) = x^2, which of the following represents a vertical shift of 3 units up?
9514 1404 393
Answer:
f(x) = x² +3
Step-by-step explanation:
The transformation
g(x) = a·f((x -c)/b) +d
represents a vertical expansion by a factor of 'a', a horizontal expansion by a factor of 'b' (before the horizontal shift), a horizontal (right) shift by 'c' units, and an upward shift by 'd' units.
You want only an upward shift of 3, so ...
g(x) = f(x) +3
For f(x) = x^2, the shifted function is ...
f(x) = x^2 +3
__
Other choices are ...
b. (x -3)^2 = right shift by 3
c. 3x^2 = vertical expansion by a factor of 3
d. (x +3)^2 = left shift by 3

>The rule for the translation can be written as T3, –5(x, y).
>The rule for the translation can be written as
(x, y) → (x + 3, y – 3).
>The rule for the translation can be written as
(x, y) → (x – 3, y – 3).
>Triangle ABC has been translated 3 units to the right and 5 units down.
Answer:
Option (2) and Option (5)
Step-by-step explanation:
Blue triangle ABC has been translated to form the image triangle A'B'C' (in red).
Let take a point A of ΔABC,
Coordinates of point A → (-1, 3)
Coordinates of point A' → (2, -2)
Rule for the translation will be,
A(-1, 3) → A'(2, -2)
A(-1, 3) → A'(-1 + 3, 3 - 5)
A(x, y) → A'(x + 3, y - 5)
[tex]T_{3, -5}(x, y)[/tex]
ΔABC has been translated 3 units to the right and 5 units down.
Therefore, Option (2) and Option (5) will be the correct options.
