Aaron ran 5/8 mile to his friend's house. Then he ran another 1/4 mile to the park.
Complete question : Aaron ran 5/8 mile to his friend's house. Then he ran another 1/4 mile to the park. Find Aaron's total miles ran?
Answer:
7/8 miles
Step-by-step explanation:
Given that:
Distance to friend's house = 5/8 miles
Then, Distance to park = 1/4 miles
Total. Distance ran :
(5/8 + 1/4)
L.C.M of 4 and 8 = 8
(5 + 2) / 8 = 7/8 miles
Total distance ran = 7/8 miles

x+5y=5
-x+6y=-5
Please Help Me Thank you :)
Answer:
(5, 0)
Step-by-step explanation:
For the first line, we can isolate x by subtracting 5y on both sides.
x=5-5y.
Now we can use substitution on the second line!
-(5-5y)+6y=-5
= -5+5y+6y=-5
=-5+11y=-5
=11y=0
y=0
We subsitute y for the first line,
x+5(0)=5
x+0=5
x=5
We can check our work by plugging in x and y
5+5(0)=5 ✔
-5+6(0)=-5 ✔

A community is building a new outdoor basketball court. The length of the court is twice the width.
Answer:
Step-by-step explanation:
The width of the basketball court is given by W(A) = √(A/2), and the length is given by L(A) = √(2A). These expressions allow you to calculate the width and length of the court for a given area A in square feet.
The problem states that the width of the basketball court (W) can be modeled by the equation:
W(A) = √(A/2)
where A is the area of the court in square feet.
Since the length (L) of the basketball court is twice the width (W), we can express it as:
L = 2W
Now, let's find the expression for the length (L) in terms of the area (A) of the court.
Step 1: Substitute the value of W from the given model into the expression for L:
L = 2 × √(A/2)
Step 2: Simplify the expression:
L = √(4A/2)
L = √(2A)
So, the expression for the length (L) of the basketball court in terms of its area (A) is given by L = √(2A).
To summarize, the width of the basketball court is given by W(A) = √(A/2), and the length is given by L(A) = √(2A). These expressions allow you to calculate the width and length of the court for a given area A in square feet.

Answer:
8 = x
y = 29
Step-by-step explanation:
4x + 17 = y + 20 because vertical angles theorem.
y + 20 = 5x + 9 because interior angles theorem.
4x + 17 = 5x + 9 because same side interior angles theorem.
Subtract 9 from both sides and subtract 4x from both sides.
8 = x
Plug 8 in for x and solve.
5 times 8 is 40, plus 9 equals 49. Subtract 20 from both sides and you get 29.
5(8) + 9 = y + 20
49 = y + 20
29 = y

"A rectangle has a height of 5 cm and its base is increasing at a rate" of 3/2 cm/min. When its area is 60 cm2, at what rate is the diagonal of the rectangle increasing?
The rate at which the diagonal of the rectangle is increasing is 18/13 cm/min.
To find the rate at which the diagonal of the rectangle is increasing, we can use the relationship between the sides of the rectangle, its area, and the diagonal.
Given that Height of the rectangle (h) = 5 cm
The rate at which the base is increasing (db/dt) = 3/2 cm/min
Area of the rectangle (A) = 60 cm²
We can determine the base (b) using the formula for the area of a rectangle:
A = b x h
60 = b x 5
b = 12 cm
Next, the Pythagorean theorem:
d² = b² + h²
d² = 12² + 5²
d² = 144 + 25
d² = 169
d = 13 cm
Now, to determine the rate at which the diagonal is increasing (dd/dt), we can differentiate the equation for the diagonal with respect to time:
d² = b² + h²
2d x (dd/dt) = 2b x (db/dt) + 0 x (dh/dt)
2d x (dd/dt) = 2b x (db/dt)
(dd/dt) = (b (db/dt)) / d
Substituting the known values:
(dd/dt) = (12 x (3/2)) / 13
(dd/dt) = 36/26
(dd/dt) = 18/13 cm/min
Therefore, the rate at which the diagonal of the rectangle is increasing is 18/13 cm/min.

The air conditioning unit for marcus building has the shape of a cube and has a volume of 0.512 cubic meters.This air conditioner will be replaced with another cube-shaped unit with a volume of 1 cubic meter. By how much will the edge length of the air conditioner change?
Answer:
The edge length of the air conditioner changed by 0.2m
Step-by-step explanation:
The volume of a cube is S^3
The edge length of the former unit is cube root of 0.512 which is 0.8 m
The edge length of the new is cube root of 1 which is 1 m

Answer: I think it’s 0.1 or 1/10 but I’m kinda confused
Step-by-step explanation: someone pls correct me if I’m wrong
1/2 is 0.5
2/5 is 0.4
0.5-0.4=0.1
0.1=1/10
1/10 of carrot, fluffy will eat at night.
What is fraction?Fractions represent the parts of a whole or collection of objects. A fraction has two parts. The number on the top of the line is called the numerator, below one is called denominator
Given,
Fluffy bunny ate 1/2 of a carrot in the morning
By the end of the day he ate 2/5 of left carrot = 2/5
Whole carrot can be considered as 1.
Carrot left after eating 1/2 of it in the morning
= 1 - 1/2
= 1/2
Carrot left after eating 2/5 part
= 1/2 - 2/5
= (5 - 4)/10
= 1/10
Hence, fluffy ate 1/10 of carrot at night.

Answer:
Total volume of the rectangular prism = 54 cubic centimeters
Step-by-step explanation:
Volume of a single layer in a rectangular prism = 9 cubic centimeters
There are 6 layers in the rectangular prism
What is the total volume, in cubic centimeters, of the rectangular prism?
Total volume of the rectangular prism = Volume of a single layer in the rectangular prism × number of layers in the prism
= 9 cubic centimeters × 6 layers

Answer:
h = 100
Step-by-step explanation:
plz mark my answer as brainlist plzzzz vote me also
Answer:
100°
Step-by-step explanation:
Ok so it looks overwhelming at first, but you just need to make sections and break it down
You are looking for h°, so you want to make it a triangle
The angles of this triangle would be h°, 40°, and x°
You can find x° by using the 140° on the same line
it is a straight line, so that means its angle is 180°
180° - 140° = 40°
x° = 40 °
so now you know that the angles in the triangle are h°, 40°, and 40°
Every triangle has angles that measure to 180°
180° - 40° - 40° = 100°
h° = 100°

Ms. Raab and Ms. Levy both drink coffee in the
mornings.
Ms. Raab adds 1 more teaspoon to each cup of
coffee than Ms. Levy. Together, they both add 5
teaspoons of sugar to their coffees.
How many teaspoons of sugar does Ms. Raab add?
How many teaspoons does Ms. Levy add?
Set up an equation to show this, and then solve.
Answer:
Ms Levy = 2
Ms Rabb = 3
Step-by-step explanation:
Let :
Number of teaspoons taken by Ms Levy = x
Number of teaspoons taken by Ms Rabb = x + 1
Total number of teaspoons taken by both = 5
(Number of teaspoons taken by Ms Rabb + Number of teaspoons taken by Ms Levy) = total number of teaspoons taken
x + 1 + x = 5
2x + 1 = 5
2x = 5 - 1
2x = 4
x = 4/2
x = 2
Hence,
Number of teaspoons of sugar added by Ms Levy = x = 2
Number of teaspoons of sugar added by Ms Rabb = x + 1 = 2 + 1 = 3
