Here is your equation:
In this equation, you're looking for the value of d alone. That means you would have to move everything next to the variable to the other side. You can do that by doing the opposite of what's being done to it.
In this equation, 5d is being subtracted by 10(-10). The opposite of that is adding 10(+10). You would have to add 10 to both sides, since -10 and +10 cancel out each other.
The first thing you are going to do is add 10 to both sides.
Now you're left with the equation 5d=30. Remember that you're looking for d alone. In the current equation, d is being multiplied by 5(5d ⇒ 5 × d). Again, you're going to do the opposite of what's being done to it. The opposite of multiplying is dividing, therefore, you're going to divide both sides by 5, since the 5 divided by 5 is 1, which cancels out the 5.
Divide both sides by 5.
That means the answer to your equation is d = 6.
Answer:
d = 6
Step-by-step explanation:
Let us follow these steps to make d the subject.
First, add 10 to both sides.
5d - 10 = 20
5d = 10+ 20
5d = 30
Divide both sides by 5.
d = 6
Statements A, B, and C are true.
Step-by-step explanation:
Step 1:
A cone, a cylinder and a sphere all have radii of 3 inches. The cone and cylinder have heights of 2 inches.
The volume of the cone, Here r = 3 inches and h = 2 inches.
So the volume of the cone cubic inches.
The volume of the cylinder, Here r = 3 inches and h = 2 inches.
So the volume of the cylinder = cubic inches.
The volume of the sphere, Here r = 3 inches.
So the volume of the sphere cubic inches.
Step 2:
Now we check to see which statements are true.
A. About 113 cubic inches of catnip will fit inside a sphere-shaped toy so it is true.
B. About 18.8 cubic inches of catnip will fit inside a cone-shaped toy so it true.
C. The sphere-shaped toy holds the most of the three so it is true.
D. No shape holds 169.6 cubic inches, so D is false.
E. The toys shaped like a cone and a cylinder do not hold the same amount of catnip in them. So it is false.
P.S. I couldn't see the options B, D, and E completely.
Answer and step-by-step explanation:
The box must be 5 inches long.
The formula for the volume of a rectangular prism (a box) is
V = length*width*height
The volume of 200, the height is 10 and the width is 4. This gives us
200 = length*10(4)
Letting x be the length,
200 = x(10)(4)
200 = 40x
Divide both sides by 40:
200/40 = 40x/40
5 = x
What is the actual distance between the two places?
Answer:
14,800in^2
Step-by-step explanation:
ok so to find the area of a trapezoid, we use the equation A=((a+b)/2)h. So Area is equal to base a (the one on the top) plus base b (the one on the bottom) divided by two (so a+b/2) and then multiply that number by h (the height. So we do it like this
(145+225)/2 x 80
But remember, we follow PEMDAS, so we multiply first
(a+b)80
370(80)= 29600
now we can divide
29600/2= 14,800sq in (or in^2)
14800
(145+225)x80 and divided by 2
b. (6, –8)
c. (–4, 3)
d. (1, –1)
