Lyla is planning on riding his bike no more than 65 miles during the week. She has already ridden 17 miles. Write and solve an inequality to find how many more miles she can ride. Then interpret the solution.
Answer:
17 + m ≤ 65
Step-by-step explanation:
Maximum distance = 65 miles
Number of miles already ridden = 17
Expression to represent how many more miles, 'm' she can ride ;
Number of miles already ridden + m ≤ maximum distance
17 + m ≤ 65
m ≤ 65 - 17
m ≤ 48
The amount of additional miles Lyla can ride is at most 48 miles
Add 2 to both sides of the equation.
So, I have this half-done equation, and the next step is to add 2 to both sides, how do I do that? Please help with a legit answer, thankyou so much!
x^3=∛(x-2)
Answer:
x = -1.135 (approx).
Step-by-step explanation:
x^3 = ∛(x - 2)
Cube both sides:
x^9 = x - 2
Subtract x and add 2 to both sides:
x^9 - x + 2 = 0
We could solve this for real roots by drawing a graph.
I did this and got one root x = -1.135 (approx).
The other 8 roots are complex.

Step-by-step explanation:
[tex]\triangle{PQR}[/tex] is a right triangle. Use the Pythagorean Theorem:
(leg)^2 + (leg)^2 = (hypotenuse)^2
The length of PR is r + 4; it's the hypotenuse.
[tex]PQ^2+QR^2=PR^2[/tex]
[tex]r^2+8^2=(r+4)^2 \\ r^2+64=r^2+8r+16 \\ 64=8r+16 \\ 48=8r \\ 6=r[/tex]
Remember, to expand [tex](r+4)^2[/tex] you multiply [tex](r+4)(r+4)[/tex]

x<-4 is the correct answer
Solve the right triangle. Round decimal answers to the nearest tenth.
Answer:
See solution below
Step-by-step explanation:
According to pythagoras theorem
hyp^2 = opp^2 + adj^2
10^2 = 4^2 + b^2
100 = 16 + b^2
b^2 = 100-16
b^2 = 84
b = √84
b ≈ 9
Using SOH CHA TOA identity
sin B = AC/AB
Sin B = 9/10
B = arcsin0.9
B ≈ 64degrees
sinA = BC/AB
Sin A = 4/10
A = arcsin0.4
A ≈ 24degrees

A ball is dropped from a height of 12 feet and returns to a height that is one-
half of the height from which it fell. The ball continues to bounce half the
height of the previous bounce each time. How far will the ball have traveled
vertically when it hits the ground for the fourth time? It might be helpful to
sketch the path of the ball.
Answer:
33.75 ft
Add up every time it travels both up and down.
12 + 6 + 6 + 3 + 3 + 1.5 + 1.5 + .75 = 33.75 on the fourth landing.
Step-by-step explanation:
The ball traveled a total of 12 feet vertically when it hit the ground for the fourth time.
What is Distance?The length along a line or line segment between two points on the line or line segment.
The ball is dropped from a height of 12 feet, so we can represent this with the point (0,12) on a coordinate plane.
The ball then bounces up to a height of 6 feet (half the height of the previous bounce), so we can represent this with the point (1,6) on the coordinate plane.
The ball then bounces down to a height of 3 feet (half the height of the previous bounce), so we can represent this with the point (2,3) on the coordinate plane.
The ball then bounces up to a height of 1.5 feet (half the height of the previous bounce), so we can represent this with the point (3,1.5) on the coordinate plane.
The ball then hits the ground for the fourth time.
The distance of the first bounce is 12 - 6 = 6 feet.
The distance of the second bounce is 6 - 3 = 3 feet.
The distance of the third bounce is 3 - 1.5 = 1.5 feet.
The distance of the fourth bounce is 1.5 - 0 = 1.5 feet
The total distance the ball traveled vertically is: 6 + 3 + 1.5 + 1.5 = 12 feet
Hence, the ball traveled a total of 12 feet vertically when it hit the ground for the fourth time.

a college loan of 15000 has a 3% annual simple interest rate what is the interest the student will pay after 5 years
Answer:
Interest = $ 90000
Step-by-step explanation:
Given, Principal= $15000
Rate = 3%
Time = 5 years
Interest = P × R × T/100
Therefore, Interest = 15000 × 3 × 5/100
(dividing 100 by 5 to get 20)
= 15000 × 3 × 20
= 90000

70% of the 60 coffee mugs at Zeke's Pancake House are dirty. How many dirty coffee mugs are there at the pancake house?
Answer:
42
Step-by-step explanation:
Since 70% is just 70/100 or 0.70, you would multiply it by the 60 coffee mugs to find out how many of the coffee mugs are dirty.
Work:
60 * 0.70 = 42
This means that 42 of the coffee mugs are dirty out of the 60 coffee mugs.

Answer:
A a. 25 minutes
Step-by-step explanation:
Let x = time in minutes.
Aquarium I contains y water at time x.
y = 4.6 + 1.2x
Aquarium II contains y water at time x,
y = 54.6 - 0.8x
We want the amounts of water to be equal, so we set the right parts of the equations equal and solve for x, the time in minutes.
4.6 + 1.2x = 54.6 - 0.8x
Subtract 4.6 from both sides.
Add 0.8x to both sides.
2x = 50
Divide both sides by 2.
x = 25

Does the function f(x) = 2(x-2)^2+3 have a minimum or a maximum? What is the minimum or maximum? Justify your answer.
Answer:
Hello. It does have a maximum and minimum. You would have to use the formula x=-b/2a to find both of them. So first you have the equation which is x=2(x-2)^2+3, which you would have to make it an equation which is equals to F(x)=2x^2-8x+11. So b would be 8 and a would be 2. Enter them into the formula. So the answers would be (2,3)

What is Transformation?A transformation is a method of modifying a polygon or other two-dimensional object on a plane or coordinate system.
Dilation - When the image becomes larger or smaller than the preimage, it is said to be "shrinking" or "enlarging."A reflection is a mirrored preimage; "a flip.""A turn" - The picture is the preimage rotated around a fixed point.Shear - All of the points along one side of a preimage remain stationary, while all of the other points move parallel to that side in proportion to the distance from the given side; "a skew."Translation - The image is offset from the preimage by a constant value; "a slide."If a translation (x, y) - (x + 6. y-10) is applied to figure ABCD.
Then, the coordinates after Translation
A (-3, 4) -----> A'( -3 +6 , 4 -10)-----> A'(3, -6)

A) 1d + 12 = 14-20
B) 4(20+5) = 10r
C) -2(5 + x) - 1 = 3(x + 3)
Answer:
A) -18 B) r=10 C) x=-4
Step-by-step explanation:
A) 1d + 12 = 14-20
Step 1: Simplify both sides of the equation.
1d+12=14−20
d+12=14+−20
d+12=(14+−20)(Combine Like Terms)
d+12=−6
d+12=−6
Step 2: Subtract 12 from both sides.
d+12−12=−6−12
d=−18
Answer:
d=−18
B) 4(20+5) = 10r
Step 1: Simplify both sides of the equation.
100=10r
Step 2: Flip the equation.
10r=100
Step 3: Divide both sides by 10.
r=10
C) -2(5 + x) - 1 = 3(x + 3)
Step 1: Simplify both sides of the equation.
−2(5+x)−1=3(x+3)
(−2)(5)+(−2)(x)+−1=(3)(x)+(3)(3)(Distribute)
−10+−2x+−1=3x+9
(−2x)+(−10+−1)=3x+9(Combine Like Terms)
−2x+−11=3x+9
−2x−11=3x+9
Step 2: Subtract 3x from both sides.
−2x−11−3x=3x+9−3x
−5x−11=9
Step 3: Add 11 to both sides.
−5x−11+11=9+11
−5x=20
Step 4: Divide both sides by -5.
x=−4
