Step-by-step explanation:
The following is a list of perfect Cubes
13 = 1
23 = 8
33 = 27
43 = 64
53 = 125
63 = 216
73 = 343
83 = 512
93 = 729
103 = 1000
If a variable with an exponent has an exponent which is divisible by 3 then it is a perfect cube. To get the cube root, we simply divide the exponent by 3. For example x9 is a perfect cube, its cube root is x3 . x11 is not a perfect cube.
EDMENTUM / PLATO ANSWER!!!!!!!!
CAN JUST WRITE:
= (50%)
= (69.2%) :)))))
First, let's count:
there are 26 possible outcomes for E1 (black card)
there are 4x9 = 36 possible outcomes for E2, to pick a numbered card (any color)
there are 2x9 =18 possible outcomes for E1 (black) AND E2 (numbered, spade + clower)
the probability of E1 AND E2 is the ratio of the count of possible outcomes for E1 + E2 and the count of all possible outcomes (52 choices to pick a card from the deck):
P(E1 and E2) = 18/52 (34.6%)
And as asked:
P(E1) = 26/52 = 1/2 (50%)
P(E2) = 36/52 = 9/13 (69.2%)
Answer:
45.5 sq. feet
Step-by-step explanation:
Area of trapezoid is given by 1/2(sum of parallel sides) * height of trapezoid.
In the problem
Parallel sides are bottom and top sides with length of 8.5 feet and 5.5 feet
Thus sum of Parallel sides = 8.5 feet + 5.5 feet = 14 feet
Height = 6.5 feet.
Thus,
area of trapezoid = 1/2*(14)* 6.5 feet = 7*6.5 feet = 45.5 sq. feet
The area of the trapezoid is whose sides are 8.5 feet and 5.5 feet with a height of 6.5 feet is 45.5 feet squared.
A trapezoid is a quadrilateral with parallel opposite sides and a height.
Mathematically, the area of a trapezoid can be calculated by using the expression:

b.
Common characteristics, all equations are parallel lines and are increasing function
c.
Common characteristics, all the equations pass through the origin.
d.
Common characteristics, all the equations pass through the origin and lie on the same points. The three equations are the same.
e.
The three equations intersect at (2,-2).
How many dollars did he pay per pound of rice?
dollars per pound
(b) A color printer prints 18 pages in 8 minutes.
How many pages does it print per minute?
pages per minute
Ivan paid $0.42 per pound of rice and the color printer prints 2.25 pages per minute.
(a) To find the dollars per pound, we divide the total cost by the total weight.
Dollars per pound = Total cost / Total weight
Given that Ivan bought 24 pounds of rice for $10, we can calculate: Dollars per pound = $10 / 24 pounds = $0.42 per pound (rounded to the nearest hundredth).
(b) To find the pages per minute, we divide the total number of pages by the total number of minutes.
Pages per minute = Total pages / Total minutes
Given that the color printer prints 18 pages in 8 minutes, we can calculate: Pages per minute = 18 pages / 8 minutes = 2.25 pages per minute (rounded to the nearest hundredth).
Joshua deposited
(a). $12.85 in coins
(b). $77.14 in checks
The linear equation in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.
According to the given question
Joshua deposited checks worth six times the value of the coins he deposited.
Let Joshua deposit the value of coins be x. Then the value of x will be 6x
There is total deposit of $90.
⇒ x + 6x = 90
⇒ 7x = 90
⇒ =$12.85
Therefore,
= $77.14
Hence, he deposit total $12.85 in coins and $77.14 in checks.
