2.5/6 = h/9 h=? What does this mean
Answers
Answer:
h = 3.75
Step-by-step explanation:
Step 1: Write equation
2.5/6 = h/9
Step 2: Solve for h
Cross multiply: 22.5 = 6hDivide both sides by 6: 3.75 = hRewrite: h = 3.75Step 3: Check
Plug in h to verify it's a solution.
2.5/6 = 3.75/9
0.416667 = 0.416667
Answer:
h = 3.75
Step-by-step explanation:
Given
[tex]\frac{2.5}{6}[/tex] = [tex]\frac{h}{9}[/tex] ( to solve for h, cross- multiply )
6h = 22.5 ( divide both sides by 6 )
h = 3.75

Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−2.5(−2−3x)+2.5(−4x−1)=−2x−4x
(−2.5)(−2)+(−2.5)(−3x)+(2.5)(−4x)+(2.5)(−1)=−2x+−4x(Distribute)
(7.5x+−10x)+(5+−2.5)=(−2x+−4x)(Combine Like Terms)
Step 2: Add 6x to both sides.
Step 3: Subtract 2.5 from both sides.
Step 4: Divide both sides by 3.5.

Write an equation of the line that passes through (3,7) and is parallel to the line shown.
An equation of the parallel line is y=__.
Answers
at first we should find the equation of this line so we should find a in the equation of y = a x + b and we do not care about b as it is parallel so a = ( (4 -(-2)) ÷ 1 -(-2)) = 2 so y = 2 x + b and we put x = 3 and y = 7 the result is 7 = 2×3 + b and b = 7 - 6 = 1 the equation is y = 2x + 1
if u pour all the liquid in a cone into a cylinder with the same height and radius then you will fill half of the cylinder with liquid
Answers
Answer:
No, the liquid will not fill half of the cylinderStep-by-step explanation:
The volume of a cylinder is 3 times bigger than a cone with equal radius and height
To know this we have to compare the volumes of both solids first.
Let us assume the height and radius of the cone and radius are
6 and 2 mm respectively
so that the volume of a cone is given as
Volume of cone= 1/3 πr^2h
and the volume of cylinder is given as
Volume of cylinder= πr^2h
1. Volume of cone= 1/3 πr^2h
Volume of cone= 1/3 *3.142*(2)^2(6)
Volume of cone= 75.408/3
2. Volume of cylinder= πr^2h
Volume of cone= 3.142*(2)^2(6)
Volume of cone= 75.408
From the analysis the volume of a cylinder is three times bigger the volume of a cone with similar radius and height

can someone please help me and explain how to change 2x − 3y = 9
into slope intercept form
Answers
Answer:
y=2/3x-3
Step-by-step explanation:
first, you have to isolate the y, so subtract 2x from both sides. -3y=-2x+9
Next, we must divide all sides by -3, so y=-2/-3x-3
Finally, simplify the equation to y=2/3x-3
Answer:
y=mx+b
y=2/3x + -3
2/3 is the slope points are (0,-3)
Step-by-step explanation:
2x-3y =9
subtract 2x from each side leaving it -3y = -2x +9
now divide both sides by -3 -3y/-3=-2x/-3 +9/-3
y= 2/3+ -3

Answers
Answer:
C.) T2, -4(x, y)Step-by-step explanation:
did on edge :)
The rule of translation of the triangle EFG is (c) T-2,4(x,y)
How to determine the translation rule?We have:
Pre-image: E(–3, 4), F(–5, –1), and G(1, 1).Image: E’(–1, 0), F’(–3, –5), and G’(3, –3).Taking E and E', we have:
E = (-3, 4)
E' = (-1, 0)
Subtract E from E'.
So, we have:
(x, y) = (-1 + 3, 0 - 4)
Evaluate
(x, y) = (2, -4)
This can be rewritten as:
T-2,4(x,y)
Hence, the rule of translation is (c) T-2,4(x,y)

A student did an experiment to test the hypothesis that brand name paper towels soak up water better than generic paper towels. What would be the independent variable in the student's experiment?
Answers
Answer: The independent variable is the brand and the dependant variable is the amount of water you use.
Step-by-step explanation:
The Independent variable is the condition that you change in an experiment.
The dependant variable is the condition that you measure in an experiment.
The independent variable in the student's experiment is the type of paper towel used.
In an experiment, there are three types of variables:
The independent variable : the experimenter can change or manipulate this variable in order to determine its effect on the dependent variable. The dependent variable : this is the variable whose value would be determined in the experiment.The extraneous variable : this is the variable that can affect the result of the experiment but it is not researched in the experiment.In this question the type of towel used would determine the amount of water that can be absorbed. This makes the type of towel used the independent variable. The dependent variable is the amount of water absorbed.

Omari and his two cousins received the same amount of money to go to the movies. Each boy spent $15. Afterward, the boys had $30.75 altogether. How much money did each boy receive?
Answers
Answer:
Each boy recieved $25.25 each
Step-by-step explanation:
First, you add up all the money the 3 boys spent.
15+15+15=45
Then you add the sum of the equation to the amount all the boys had afterward.
45+30.75=75.75
Finally, you divide that product to 3 boys.
75.75/3=25.25
Therfore the answer is $25.25 each.

for the equation x + y = 3. How many possible values for x are there if x and y are both whole numbers?
A.2
B.3
C.4
Answers
Answer:
A
Step-by-step explanation:
Because it is 2+1 and 3+0, those are the only solution, therefore A is correct
======================================================
Explanation:
The set of whole numbers is {0, 1, 2, 3, ...}
So we include 0 and any positive number that doesn't have decimal or fractional components to it. Negative values are not included.
If we plug in x = 0, then x+y = 3 solves to y = 3If we plug in x = 1, then x+y = 3 solves to y = 2If we try x = 2, then x+y = 3 solves to y = 1Lastly, x = 3 leads to y = 0Whatever you pick for x, the y value must add to it to get 3. Both x and y must be numbers from the set of whole numbers.
There are four cases shown in the bullet points above, so we have four different solutions. We can't move onto x = 4 because the y solution would be y = -1, but -1 is not in the set of whole numbers.

If the backpack costs $16, which equation represents the situation in which x denotes the cost per binder and y denotes the total cost of Jesse’s purchase?
Answers
The 16 is the cost of the backpack, which you add to the 3 binders which cost x each. This gives you the total, y.
Hope this is helpful!!
The equation represents the situation in which x denotes the cost per binder and y denotes the total cost of Jesse’s purchase is 16+3x=y.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Jesse wants to purchase three binders and a backpack. If the backpack costs $16
From the data given in the question:
The linear equation can be framed as follows:
y = 16 + 3x
Or
16 + 3x = y
Thus, the equation represents the situation in which x denotes the cost per binder and y denotes the total cost of Jesse’s purchase is 16+3x=y.
The options are:
16+y=3x
16+3x=y
y+3x=16
3+16x=y
