Answer:
4/5, 16/20
Step-by-step explanation:
two fractions equivalent to 8/10 are 8/10 (the original fraction itself), 16/20 (obtained by multiplying by 2), and 4/5 (obtained by dividing by 2).
To find two fractions equivalent to 8/10, we can simplify 8/10 to its simplest form and then multiply or divide the numerator and denominator by the same number to find equivalent fractions.
Step 1: Simplify 8/10 to its simplest form:
The greatest common divisor of 8 and 10 is 2. Dividing both the numerator and denominator by 2, we get 4/5.
Step 2: Find equivalent fractions:
We can multiply or divide the numerator and denominator of 8/10 by the same number to find equivalent fractions. Here are two possibilities:
Multiplying both numerator and denominator by 2:
8/10 * 2/2 = 16/20
So, two fractions equivalent to 8/10 are 8/10 (the original fraction itself), 16/20 (obtained by multiplying by 2), and 4/5 (obtained by dividing by 2).

The path of water from a hose on a fire tugboat can be approximated by the equation y = −0.0045x2 + 1.15x + 10, where y is the height, in feet, of the water above the ocean when the water is x feet from the tugboat. When the water from the hose is 3 feet above the ocean, at what distance from the tugboat is it? Round answer to nearest hundredth.
Answer:
x = 261.50 ft
Step-by-step explanation:
From the question, we want to calculate the distance from the tugboat given the height of the hose above the ocean
This means y is 3 and we want to find x
Substitute value for y
3 = -0.0045x^2 + 1.15x + 10
3 + 0.0045x^2 - 1.15x - 10 = 0
That will be;
0.0045x^2 - 1.15x - 7 = 0
we can use the quadratic formula here;
a = 0.0045
b = -1.15
c = -7
Mathematically;
x = -b ± √b^2 - 4ac/2a
Thus we have;
x = 1.15 ± √(-1.15)^2 - 4(0.0045)(-7)/2(0.0045)
We have;
x = 1.15 ± 1.2035/0.009
x = (1.15+ 1.2035)/0.009
we ignore the negative since distance cannot be negative
x = 261.50 ft

write an equation that goes through the ordered pairs (2,-1) and (4,-6)
Answer:
y = -5/2x +4
Step-by-step explanation:
Find the slope:
m = (y2 - y1) / (x2 - x1)
m = (-6 - (-1)) / (4 - 2)
m = -5 /2
y = mx + b
y = -5/2x + b
Solve for b:
y = -5/2x + b
-1 = (-5/2)(2) + b
-1 = -10/2 + b
-1 = -5 + b
b = 4
y = -5/2x + 4

The Homerun Hitter's Academy charges thirty-five dollars per hour for batting lessons, with a registration fee of fifteen dollars per year. Janice's parents paid $155 in the month of August. Part A: Using h to represent hours, write an equation to determine how many hours of batting lessons Janice had in the month of August. Part B: Solve the equation you wrote in Part A for h
Answer:
h = 4 hours
Step-by-step explanation:
Charges per hour = $35
Registration fee = $15
Janice's parents paid $155 in the month of August.
Let
h = number of hours
equation to determine how many hours of batting lessons Janice had in the month of August.
15 + 35h = 155
B. 15 + 35h = 155
35h = 155 - 15
35h = 140
Divide both sides by 35
h = 140 / 35
= 4
h = 4 hours

Help me please? I don’t really get it TT
First, you have to move the decimal point before you divide like normally. You need to move it so that the left number is a whole number.
So, 6.39/0.9 would turn into 63.9/9.
12.75/2.5 would turn into 127.5/25.
You just move the decimal how ever many times to the right to make it a whole number. In this case, it is 1 decimal place.

simplify the equation and tell whether the equation has one solution, no solution, of infinitely many solutions. 9(x+5) = 20+9x+25
Answer:
Infinite Solution
Step-by-step explanation:
no matter what you put for x you would still get 9x+45=9x+45 if you put x=8 it would equal the same on both sides
The system of equations 9(x + 5) = 20 + 9x + 25 has infiinitely many solutions.
What is the graphical solution of a system of equations?Graphical solutions of a system of equations are way of finding the intersection points of all the equations given.
A system with two or more than two equations has a solution only when they have a common intersection point.
Given, 9(x + 5) = 20 + 9x + 25.
9x + 45 = 20 + 9x + 25.
9x + 45 = 9x + 45.
So, They are basically the same straight lines coinciding with each other and have infinitely many solutions.

what is the vertex of the graph function y=4x^2+8x-2
Answer:
vertex = (-1, -6)
Step-by-step explanation:
The function you gave is in the Standard Form : y = aX^2 + bX + c.
So you use the equation x = -b/ 2a to solve for the x coordinate of your vertex.
Based on your question, a =4, b =8 and c = -2.
So you plug that in and get x = -8/2(4). Thus, x value for the vertex is -1.
Now you plug -1 into your original equation to find your y value.
y = 4 (-1)^2 + 8 (-1) -2
So y = -6. Thus, your vertex is at pt (-1, -6)

By putting every value of table x, y = (96 / x) this gives the output of table y so that this is the correct answer.
By definition, it is known that speed equals the ratio of distance and time.
Speed = Distance / Time
Therefore, according to the definition, the last two options are the possible
Let's evaluate the First option:
y = x/96
= 12/96
= 1/8
The table is not fulfilled
Let's evaluate the Second option: (12,8)
y= 2x/3
y= 2*12/3
y = 8
NOW,
(16, 6)
y= 2x/3
2*16/3
the answer will be on a fraction
The table is not fulfilled
Let's evaluate the third option:
y = (3/2) * (1 / x)
x = 12
y = (3/2) * (1/12) = 3/24 = 1/8
The table is not fulfilled
Let's evaluate the fourth option:
y = (96 / x)
x = 12
y = (96/12) = 8
Yes, the table is met.
Option 4 ) y = (96 / x)
By putting every value of table x, y = (96 / x) this gives the output of table y so that this is the correct answer.
