Step-by-step explanation:
I am not sure I understand the answer options.
but normally the answer should be "commission".
as this is the defined way of payment, when you get paid based on the items sold.
but in any case, what math question is this ?
Answer:
d=6+2t
Step-by-step explanation:
Let
t=number of ten dollar bills
d=number of dimes
Number of dimes is six more than two times the number of ten dollar bills
d=6+2*t
d=6+2t
Answer:
The height of the lamp post is 15 feet ⇒ 1st answer
Step-by-step explanation:
The ladder , the lamp post and the ground formed a right triangle, the length of the ladder is its hypotenuse (l), the height of the lamp post (h) and the horizontal distance on the ground between the base of the ladder and the base of the lamp post (d) are the legs of the triangle
By using Pythagoras Theorem ⇒ <em>the square of the hypotenuse is equal to the sum of the squares of the other two legs</em>
∵ l² = h² + d²
∵ The length of the ladder is 25 feet
∴ l = 25
∵ The ladder is placed 20 feet from the lamp post
- That means the distance between the base of the ladder and
the base of the lamp post on the ground
∴ d = 20
- Substitute the values of l and d in the Pythagoras formula
∵ (25)² = h² + (20)²
∴ 625 = h² + 400
- Subtract 400 from both sides
∴ 225 = h²
- Take √ for both sides
∴ 15 = h
∴ The height of the lamp post is 15 feet
We have to choose which expression represents the height of the prism.
The base is a square of edge length x units.
Base Area = x · x = x²
Volume of the prism = B · h
x³ = x² · h
h = x³ : x²
h = x
Answer: x units.
The solid shape is a SPHERE.
And the surface area of a sphere is given as;
Given the radius r, of the circle as 8cm and pie = 3.14;
The area of the sphere is 803.84 square centimeters
But to the nearest tenth, the area of the sphere 803.8 square centimeters
