Answer:
4d^4
Step-by-step explanation:
There is a bag with only red marbles and blue marbles.
The probability of randomly choosing a blue marble is
5/12
.
There are 72 marbles in total in the bag and each is equally likely to be chosen.
Work out how many red marbles there must be.
Answer:
42 reds.
Step-by-step explanation:
There are 72 marbles in the bag.
P(Red) = 1 - Blue = 1 - 5/12 = 7/12
P(red) = 7/12 * 72 = 42
If 1 - 5/12 confuses you, then find the blue first
5/12 * 72 = 5 * 72/12 = 5 * 6 = 30
The rest must be red.
72 - 30 = 42
Gasoline costs $3.37 per gallon. Mary's father puts 9i gallons in the tank of his car. How much will the gasoline cost?
9 gallons of gasoline would cost 30.33
9 x 3.37=30.33 you just have to multiply the gas by the gallons and then that will give you your answer
A rectangular pyramid has a volume of 32 cubic feet. Find one possible set of measurements
for the base area and height of the pyramid.
Answer:
Ghe possible set of measurements for the base area and height are;
(96, 1)
(48, 2)
(32, 3)
(24, 4)
(16, 6)
(12, 8)
Step-by-step explanation:
Formula for volume of a rectangular pyramid is;
V = ⅓Bh
Where;
B is area of base
h is height of pyramid
Thus, if volume is 32, then;
32 = ⅓Bh
Multiply both sides by 3 to get;
Bh = 96
Factors of 96 are; 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, and 96
Thus, the possible set of measurements for the base area and height are;
(96, 1)
(48, 2)
(32, 3)
(24, 4)
(16, 6)
(12, 8)
A straight road to the top of a hill is 2500 feet long and makes an angle of 12° with the horizontal. Find the height of the hill. Round to the nearest foot.
The height of the hill is 520 ft
The height of the hill, h the length of the road, L and the ground form a right angled triangle with length of the road as the hypotenuse side and the height of the hill as the opposite side to the angle the road makes with the horizontal, Ф.
Now, from trigonometric ratios,
sinФ = h/L
The height of the hillMaking h subject of the formula, we have
h = LsinФ
Since L = 2500 ft and Ф = 12°, thus
h = LsinФ
h = 2500 ft × sin12°
h = 2500 ft × 0.2079
h = 519.78 ft
h ≅ 520 ft to the nearest foot
So, the height of the hill is 520 ft

Use the Rational Root theorem to determine the factors of x^3 - 2x^2 - 13x - 10 given that one factor is (x + 1)
Answer:
The correct option is;
D. (x - 5)·(x + 2)·(x + 1)
Step-by-step explanation:
The Rational Root theorem is expressed mathematically as follows;
[tex]Possible \ rational \ roots = \dfrac{Factors \ of \ the \ constant \ term}{Factors \ of \ the \ leading \ coefficient}[/tex]
The given polynomial is presented as follows;
x³ - 2·x² - 13·x - 10
A factor of the polynomial = (x + 1)
The factors of the constant term, -10 = -10, -5, -2, -1, 10, 5, 2, and 1
The factors of the leading coefficient, (the coefficient of the variable having the highest degree or power, x³) = 1
Given that (x + 1) is a known factor, the other two factors are either (x + 5) and (x - 2) or (x - 5) and (x + 2)
The option, that combines (x + 1) and the other two factor combination is (x - 5)·(x + 2)·(x + 1)
∴ The solution which meets the condition is (x - 5)·(x + 2)·(x + 1)
We check;
(x - 5)·(x + 2)·(x + 1) = x³ - 2·x² - 13·x - 10

r = j + 3
We subtitube r to find j,
r = 9 j = 9 + 3 = 12
r = 15 j = 15 + 3 =18
r = 21 j = 21 + 3 = 24
And we found A as answes.
Answer:
CStep-by-step explanation:
r = j + 3 ⇒ j = r - 3Table C is the correct one
r = 9 ⇒ j = 6r = 15 ⇒ j = 12r = 21 ⇒ j = 18La suma de los ángulos internos de un heptágono es:
