Answer:
D/ h =q
Step-by-step explanation:
D = qh
Divide each side by h to isolate q
D/ h = dh/h
D/ h =q
Step-by-step explanation: To solve for q in the equation d = qh, all we have to do is get q by itself on the right side of the equation.
Since q is being multiplied by h, to get q by itself,
we simply divide both sides of the equation by h.
On the right, the h's cancel and we are re left with q.
On the left we have [tex]\frac{d}{h}[/tex].
So our answer is [tex]\frac{d}{h} = q[/tex].

Find the slope of the line graphed
Answer:
The slope is 3/2
Step-by-step explanation:
To find slope you do rise over run
Rise being how much you go up or go down
Run being how much you move sideways
Always measure Rise first, it is the numerator and then Run as the denominator.
Answer:
m= 3/2.
Step-by-step explanation:
To find the slope, use the two points shown in the graph which as (-1, 2) and (1, 5). Plug these into the slope formula [tex](m= \frac{y_{2}-y_{1} }{x_{2}-x_{1}} )[/tex]
[tex]m= \frac{5-2 }{{1+1}}[/tex]
[tex]m= \frac{3}{2}[/tex]
Therefore, the slope of the graph is 3/2.

A baseball team played 82 games. The team won 7 more than twice as many games as it lost. The equation l+2l+7=82 models this relationship, where l is the number of games lost. How many games did the team lose? How many games did the team win?
Answer:
The team lost 25 games and won 57.
Step-by-step explanation:
I am going to say what:
w is the number of games won.
As the problem states, l is the number of games lost.
The team won 7 more than twice as many games as it lost.
This means that [tex]w = 2l + 7[/tex]
A baseball team played 82 games.
This means that:
[tex]w + l = 82[/tex]
[tex]2l + 7 + l = 82[/tex]
[tex]3l = 75[/tex]
[tex]l = \frac{75}{3}[/tex]
[tex]l = 25[/tex]
And
[tex]w = 2l + 7 = 2*25 + 7 = 57[/tex]
The team lost 25 games and won 57.

There are eight black socks six blue socks and 14 White Sox in a drawer if one sock is randomly chosen from the drawer than what is the probability that the sock not be blue
Answer:
The probability that the socks picked is not blue is 11/14
Step-by-step explanation:
In this question, we are to calculate that a socks selected from random from the group of socks given in the question is not a blue socks.
This means the socks would either be a black or a white socks
Firstly, we find the total number of socks = 8 + 6 + 14 = 28 socks
Now the probability of picking a blue socks will be 6/28 = 3/14
We must understand that the probability of not picking a blue socks = 1 - the probability of picking a blue socks
Thus, the probability of not picking a blue socks will be 1 - 3/14 = 11/14
Answer:
The probability that a sock chosen at random is not blue P = 11/14 = 0.786
Step-by-step explanation:
Probability is the chances of getting a particular outcome.
Given:
Black socks = 8
Blue socks = 6
White socks = 14
Total = 8+6+14 =28
The probability that a sock chosen at random is not blue P;
P = number of non-blue socks ÷ total number of socks
Number of non blue socks = black + white socks = 8+14 = 22
Substituting the values;
P = 22/28 = 11/14
P = 11/14 = 0.786
can someone help me with exercise 1 please
Answer:
A) 5X+6=2X+30
6 = -3X+ 30 (Subtracted 5X from both sides)
-24 = -3X (Subtracted 30 from both sides)
8 = X (divide -3 from both sides)
B) Isolate the variable by dividing each side by factors that don't contain the variable. x = 8
Nadia drew a design for a copper wire sculpture as shown above.She plans to make a wire frame that includes the perimeter of the square and the circumference of the circle.She has 5 feet of copper wire.Does she have enough wire for the sculpture?
Answer:
She does not have enough wire.
Step-by-step explanation:
The complete question included a design for her sculpture. It is a circle inscribe in a square and the length of the square is 9 inches. The picture above describe the design.
She has in possession a 5 ft of copper to construct a circle inscribe in a square.
The square is 9 inch length.
Perimeter of the square = 4L
where
L = length
Perimeter of the square = 4 × 9
Perimeter of the square = 36 inches
Circumference of a circle = 2πr
r = diameter/2 = 9/2 = 4.5 inches
Circumference of a circle = 2 × π × 4.5
Circumference of a circle = 2 × 4.5 × 3.14
Circumference of a circle = 9 × 3.14
Circumference of a circle = 28.26 inches.
The sculpture will consume 36 inches for the square and 28.26 inches for the circle. The total length for the sculpture will be 36 + 28.26 = 64.26 inches.
She has 5 ft copper for the sculpture . Let us covert the inches to ft to know if the copper wire is enough.
12 inches = 1 foot
64.26 inches = ?
cross multiply
wire required for the sculpture = 64.26/12
wire required for the sculpture = 5.355 ft
She does not have enough wire.
Answer:
No she does not have enough

Find the circumferences of the two circles circle a has a radius of 21 meters and circle b has a radius of 28 meters Is the relationship between the radius of a circle and the distance around the circle the same for all circles
Answer:
The circumference for circle a is [tex] \\ C = 131.9430[/tex]m.
The circumference for circle b is [tex] \\ C = 175.9240[/tex]m.
The relationship between the radius of a circle and the circumference (the distance around the circle) is constant and is the same for all circles and can be written as [tex] \\ \frac{C}{r} = 2\pi[/tex] or, in a less familiar form, [tex] \\ \frac{r}{C} = \frac{1}{2\pi}[/tex]. The number [tex] \\ \pi[/tex] is constant for all circles and has infinite digits, [tex] \\ \pi = 3.14159265358979....[/tex].
Step-by-step explanation:
The circumference of a circle is given by:
[tex] \\ C = 2*\pi*r[/tex] [1]
Where
[tex] \\ C[/tex] is the circle's circumference.
[tex] \\ r[/tex] is the radius of the circle.
And
[tex] \\ \pi = 3.141592....[/tex] is a constant value (explained below)
We can say that the distance around the circle is the circle's circumference.
The circumferences of the two circles given are:
Circle a, with radius equals to 21 meters ([tex] \\ r = 21m[/tex]).
Using [1], using four decimals for [tex] \\ \pi[/tex], we have:
[tex] \\ C = 2*\pi*r[/tex]
[tex] \\ C = 2*3.1415*21[/tex]m
[tex] \\ C = 131.9430[/tex]m
Then, the circumference for circle a is [tex] \\ C = 131.9430[/tex]m.
Circle b, with radius equals to 28 meters ([tex] \\ r = 28m[/tex]).
[tex] \\ C = 2*3.1415*28[/tex]m
[tex] \\ C = 175.9240[/tex]m
And, the circumference for circle b is [tex] \\ C = 175.9240[/tex]m.
We know that
[tex] \\ 2r = D[/tex]
That is, the diameter of the circle is twice its radius.
Then, if we take the distance around the circle and we divided it by [tex] \\ 2r[/tex]
[tex] \\ \frac{C}{2r} = \frac{C}{D} = \pi[/tex]
This ratio, that is, the relationship between the distance around the circle (circumference) and the diameter of a circle is [tex] \\ \pi[/tex] and is constant for all circles. This result is called the [tex] \\ \pi[/tex] number, which is, approximately, [tex] \\ \pi = 3.141592653589793238....[/tex] (it has infinite number of digits).
We can observe that the relationship between the radius of a circle and the circumference is also constant:
[tex] \\ \frac{C}{2r} = \frac{C}{D} = \pi[/tex]
[tex] \\ \frac{C}{2r} = \pi[/tex]
[tex] \\ \frac{C}{r} = 2\pi[/tex]
However, this relationship is [tex] \\ 2\pi[/tex].
We can rewrite it as
[tex] \\ \frac{r}{C} = \frac{1}{2\pi}[/tex]
And it is also constant.
Answer:
Circle A is 42π
circle C is 56π

You pick a card at random. Without putting the first card back, you pick a second card at random.
What is the probability of picking a 3 and then picking a 5?
Simplify your answer and write it as a fraction or whole number.
Answer:
You have three card : 3, 4, and 5.
You first pick one card randomly, the probability of picking a 3 is:
P = 1/3
You then pick a second card without putting the first card back, the probability of picking a 5 is:
P = 1/2
=> The probability of picking a 3 and then picking a 5:
P = (1/3) x (1/2) = 1/6
