There are 3 feet in 1 yard. How many feet are equal to 10 yards
Answer:
30 feet
Step-by-step explanation:
There a 3 ft in a yard
If there's 10 yards
then multiply 10 x 3 to get 30 feet
Can someone actually help me with this
Answer: X = 30*
All circles = 360*
we can subtract 260 from that because we know the length of one so we know the other is 130.
We are then left with only 100 and we know the two sides are equivalent so 100 / 2 = 50

The velocity V of an object dropped from a tall building is given by V = V64d, where dis
the distance, in feet, the object has dropped. Find the distance when the velocity is
32 ft/sec.
Answer:
d = 0.0625 m
Step-by-step explanation:
The velocity of an object dropped from a tall building is given by :
[tex]v=\sqrt{64d}[/tex]
Where
d is the distance in feet
We need to find the distance when the velocity is 32 ft/s
Rearranging for d,
[tex]v^2=64d\\\\d=\dfrac{64}{v^2}[/tex]
Put v = 32 ft/s
[tex]d=\dfrac{64}{32^2}\\\\d=0.0625\ m[/tex]
So, the required distance is 0.0625 m.
Evaluate 18 divided by q when q=1/2
Question:
Evaluate 18 divided by q when q = 1/2
__________________________________________________
Answer:
18 divided by q
= 18/q
When q = 1/2,
= (18) / (1/2)
The 2 from the denominator of (1/2) will go up to the numerator of (18) / (1/2). We will be left with,
= (18 * 2) / (1)
= 36/1
= 36

If P = 3x2 + xy - 5y? Q = 2x2 - xy + 3y2 and R = -6x2 + 4xy - 7y2?
what is P+Q-R?
Answer:
is this helpful tell me please if im correct :)
Answer:
[tex]P+Q-R=11x^2-4xy+10y^2[/tex]
Step-by-step explanation:
I'm assuming the 2's at the end of some of the terms are meant to be exponents. So here we have
[tex]P=3x^2+xy-5y\\Q=2x^2-xy+3y^2\\R=-6x^2+4xy-7y^2[/tex]
and we're asked to find P + Q - R. Let's handle these operations left to right to cut down on clutter. Starting with P + Q, our first job should be to combine all the like terms we can. 3x² + 2x² = 5x², and xy - xy = 0, but we still can't do anything with the terms -5y and 3y². So far, this gives us
[tex]P+Q=5x^2-5y+3y^2[/tex]
Now let's handle subtracting R from this sum. The pairs of like terms here are 5x² and -6x², and 3y² and -7y². Subtracting these parts gives us 5x² - (-6x²) = 11x² and 3y² - (-7y²) = 10y², and we can subtract off the remaing 4xy in R to give us
[tex]P+Q-R=11x^2-4xy+10y^2[/tex]

How many moles of water are produced when 3.0 moles of hydrogen gas reacts with 1.8 moles of oxygen gas?
Balanced equation: 2H2 + O2 + 2H20
O 3.0 moles of water
O 3.6 moles of water
O 5.3 moles of water
O 7.0 moles of water
Answer:
3 moles of water are produced
Step-by-step explanation:
Find the limiting reactant
3.0 moles of H2 x (2 moles of H2O/2moles of H2)=3.0 moles of H20--limiting reactant, so this is the maximum amount of product that can be produced! Hope this helps
1.8 moles of O2 x (2 moles of H20/1 moles of O2)=3.6 moles of H20
3.6 moles of water are produced when 3.0 moles of hydrogen gas reacts with 1.8 moles of oxygen gas.
What is mole ?In chemistry, a mole is a unit of measurement used to quantify the amount of a chemical. It is defined as the amount of a substance containing Avogadro's number of entities (about 6.022 x [tex]10^{23[/tex]particles). The mole is a unit of measurement that is used to express the amount of a substance in terms of its molecular or atomic count. The mole is especially important in chemical reactions, where it is used to balance the number of atoms or molecules present in the reactants and products.
We have the balanced Equation:
2[tex]H_2[/tex] + [tex]O_2[/tex] ----> 2[tex]H_2O[/tex]
As, 3.0 moles of Hydrogen gas reacts with 1.8 moles of oxygen gas.
So, 1.8 moles of [tex]O_2[/tex] x (2 moles of [tex]H_2O[/tex] /1 moles of [tex]O_2[/tex])
= 3.6 moles of [tex]H_2O[/tex]
Also, 3.0 moles of Water is the limiting reactant.

Answer: The walking path around it.
Step-by-step explanation:
Remember the Pythagorean's theorem, for a triangle rectangle with catheti A and B, and with hypotenuse H, we have:
A^2 + B^2 = H^2
or
H = √(A^2 + B^2)
Here, A + B is the total distance for the path, while the hypotenuse is the distance for the bridge
Here we can see that:
A = 1170 ft
B = 520 ft
Then:
H = √( (520 ft)^2 + (1170 ft)^2) = 1280.4 ft
Now, let's compute the costs.
For the bridge, we know that each foot costs $11, then for 1280.4 ft the cost is:
Cost of the bridge = (1280.4)*$11 = $14,084.4
And for the walking path, the cost is $6 per foot, then the total cost of the path is:
Cost of the path = (520 ft + 1170 ft)*$6 = $10,140
We know that the bridge is preferred if it is within the range of $1500 for the path's cost.
This range is:
($10,140 - $1,500, $10,140 + $1,500) = ($8,640, $11,640)
Here we can see that the cost of the bridge does not belong to this range, (is higher) so the option we should recommend is the walking path around.

Please help I need to pass my class
Answer:
Step-by-step explanation:
sin(D) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{7}{14}[/tex]
= [tex]\frac{1}{2}[/tex]
= 0.5
cos(D) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{12.124}{14}[/tex]
= 0.866
tanD = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{7}{12.124}[/tex]
= 0.577
Since, sinE = cosD
Therefore, sinE = 0.866
Since, cosE = sinD
Therefore, cosE = 0.5
Since, tanE = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{12.124}{7}[/tex]
= 1.732
A circle is centered at (0,0) and has a radius of 2\sqrt{3}
Where does the point M(−3,2) lie?
Answer:
Outside of the circle
Step-by-step explanation:
First, find the equation of the circle by plugging in the center point and radius:
(x - h)² + (y - k)² = r²
(x - 0)² + (y - 0)² = ([tex]2\sqrt{3}[/tex])²
x² + y² = 12
Plug in point M to see where it lies:
x² + y² = 12
(-3)² + (2)² = 12
9 + 4 = 12
13 ≠ 12
Since this statement is false, point M lies outside of the circle.

A system of linear equations has infinitely many solutions. What is known about the slopes and y-intercepts of the graphed equations? Explain your reasoning.
Answer:
The answer is below
Step-by-step explanation:
The graph of a linear function can be represented as:
y = mx + b;
where y and x are variables, m is the slope of the graph and b is the y intercept.
A system of linear equations has infinitely many solutions, when the lines overlap at every point. In other words, they're the same exact line, having the same equation when simplified.
This means that they have the same slope and y intercepts

Which of these strategies would eliminate a variable in
the system of equations?
8x + 8y = 2
8x + 5y = 1
Answer:x = -1 / 12
Step-by-step explanation: am i right??
8x + 8y = 2 -------(1)
8x + 5y = 1 -------(2)
subtract equation (2) from equation (1)
The 8x will be eliminated, leaving us with;
3y = 1
Divide bothside of the equation by 3
y = 1/3
substituting y = 1/3 in equation (1)
8x + 8y = 2
8x + 8(1/3) = 2
8x + 8/3 = 2
subtract 8/3 from both-side
8x + 8/3 -8/3 = 2 -8/3
8x = 2 - 8/3
8x = 6 - 8 / 3
8x = - 2/3
Divide both-side of the equation by 8
8x / 8 = -2/3 ÷ 8
x = -2/3 × 1/8
x = -1 / 12
