A horticulture class is filling planters with soil. Each planter is to be filled full.
How many cubic feet of soil will be needed to fill 15 planters measuring 2 feet by
3 feet by 1 foot?
O a.) 55 cu ft
Ob.) 45 cu ft
Oc.) 35 cu ft
O d.) 48 cu ft
Answer:
90 ft³
Step-by-step explanation:
V = LWH
V = (2 ft)(3 ft)(1 ft)
V = 6 ft³
Each planter has a volume of 6 ft³.
total volume = 15 × 6 ft³ = 90 ft³
A greedy hamster hoarded 2 piles of sunflower seeds. Yesterday the ratio of the seeds in these piles 3:4; but today the greedy hamster placed another 2 pounds of seeds in the bigger pile. He also ate 1/4 pound from the smaller pile and now the quantities of seeds in those piles is in the ratio of 5:16. What was the weight of each pile yesterday
The weight of each pie will be 6 and 8 pounds respectively if the ratio of the seeds in these piles 3:4
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
We have:
A greedy hamster hoarded 2 piles of sunflower seeds. Yesterday the ratio of the seeds in these piles was 3:4
Let 3x and 4x are the seeds from the smaller and bigger pile.
= 4x + 2 (greedy hamster placed another 2 pounds of seeds in the bigger pile)
= 3x - 1/4 (ate 1/4 pound from the smaller pile)
4x + 2 = 5x
Because the quantities of seeds in those piles is in the ratio of 5:16
After solving:
x = 2
Smaller pile weight = 3x = 3(2) = 6
Bigger pile wieght = 4x = 4(2) = 8
Thus, the weight of each pie will be 6 and 8 pounds respectively if the ratio of the seeds in these piles 3:4

Factor by Grouping.
25x^2-20x-12
Answer:
ac = -300-20 = -30 +10(5x +2)(5x +(-6))Step-by-step explanation:
The sequence of required answers provides a step-by-step solution to the problem.
Factors of acIn the given trinomial, we identify the coefficients as ...
ax² +bx +c = 25x² -20x -12 ⇒ a=25; b=-20; c=-12
Then the ac product is ...
ac = (25)(-12) = -300
The factor pairs that make this product can be listed as ...
-300 = (-300)(1) = (-150)(2) = (-100)(3) = (-75)(4) = (-60)(5) = (-50)(6) = (-30)(10) = (-25)(12) = (-20)(15) . . . . (only pairs with a negative sum are listed)
The sums of these pairs are -299, -148, -97, -71, -55, -44, -20, -13, -5.
The factors of the ac product that add to -20 are -30 and 10.
Factor by groupingThese factors are used to rewrite the -20x term as a sum.
25x² -20x -12 = 25x² -30x +10x -12
Grouping these terms in pairs, we can identify common factors:
= (25x² -30x) +(10x -12)
= 5x(5x -6) +2(5x -6)
= (5x +2)(5x +(-6))
Write out the form of the partial fraction decomposition of the function. Do not determine the numerical values of the coefficients.[tex]\frac{t^4+t^2+1}{(t^2+4)(t^2+2)^2}[/tex]
The form of the partial fraction decomposition is [tex]\frac{At + B}{(t^2 + 4)} + \frac{Ct + D}{(t^2 + 2)} + \frac{Et + F}{(t^2 + 2)^2}[/tex]
How to decompose the function?The fraction is given as:
[tex]\frac{t^4 + t^2 + 1}{(t^2 + 4)(t^2 + 2)^2}[/tex]
To decompose the above, we make use of the following rule:
[tex]\frac{px^n + qx^m +....+ r}{(x^2 + a)(x^2 + b)^2} = \frac{Ax + B}{(x^2 + a)} + \frac{Cx + D}{(x^2 + b)} + \frac{Ex + F}{(x^2 + b)^2}[/tex]
So, we have:
[tex]\frac{t^4 + t^2 + 1}{(t^2 + 4)(t^2 + 2)^2} = \frac{At + B}{(t^2 + 4)} + \frac{Ct + D}{(t^2 + 2)} + \frac{Et + F}{(t^2 + 2)^2}[/tex]
Hence, the form of the partial fraction decomposition is [tex]\frac{At + B}{(t^2 + 4)} + \frac{Ct + D}{(t^2 + 2)} + \frac{Et + F}{(t^2 + 2)^2}[/tex]

The slope and the y-intercept of the function are: A. Slope = -2/5; y-intercept = -1/3.
How to Find Slope and Y-intercept of a Linear Function?Slope (m) = change in y / change in x.
Using two pairs of points form the table value, (1/4, -13/30) and (2/3, -3/5)"
Slope (m) = (-13/30 - (-3/5))/(1/4 - 2/3)
Slope (m) = (-13/30 + 3/5))/(1/4 - 2/3)
Slope (m) = (1/6)/(-5/12)
Slope (m) = (1/6)(12/-5) = 12/-30
Slope (m) = -2/5
Plug in m = -2/5 and (x, y) = (2/3, -3/5) into y = mx + b to find the y-intercept (b).
-3/5 = -2/5(2/3) + b

Chris is mixing 2 different types of fruit juice together for a summer drink. The two types of juices he is using is one that is 30% strawberry concentrate and the other is 55% lemon concentrate. If he wants 2 L that is 40% concentrate of the fruit juices, how much of each should be used to create the drink?
The total amount of the drink is 2L. Strawberry concentrate will be X amount, and lemon concentrate will be the other part which is 2 - X.
---Note that we can only use one variable because there is only one equation to be set up here. That's why "the other part" is simply the total amount minus the strawberry amount.
0.4(2) = 0.3(x) + 0.55(2 - x)
---0.4, 0.3 and 0.55 are the decimal equivalents of 40%, 30% and 55%
0.8 = 0.3x + 1.1 - 0.55x
0.8 = -0.25x + 1.1
-0.3 = -0.25x
x = 1.2
Therefore, Chris should use 1.2L of strawberry concentrate and 0.8L of lemon concentrate to get 2L of a 40% concentrate mixture.

The final displacement is 2cm in the right.
Given that the object begins from 0 and moves 3 cm towards the left side and then, 5 cm towards the right side.
The displacement is known as shortest distance between the initial and final positions.
Let the x-axis be the positive, +ve, and on the right side and negative -ve on the left side.
Thus, displacement would be:
D= 0 -3 +5
D= 2 cm

let (-5,-7) be a point on the terminal side of theta. find the exact values of cos theta, sec theta, and cot theta
a. The exact value of cosθ = -5/√74
b. The exact value of secθ = -√74/5
c. The exact value of cotθ = 5/7
How to find the trigonometric ratios
Since the terminal side of the θ is the point, (-5, -7), we need to find the length of the terminal side.
So, r = √(x² + y²) where
x = -5 and y = -7So, r = √(x² + y²)
r = √((-5)² + (-7)²)
r = √(25 + 49)
r = √74
The value of the trigonometric ratio cosθ
Since the trigonometric ratio cosθ = x/r
Substituting the values of x and r into the equation, we have
cosθ = x/r
cosθ = -5/√74
So, the exact value of cosθ = -5/√74
The value of the trigonometric ratio secθSince the trigonometric ratio, secθ = r/x
Substituting the values of x and r into the equation, we have
secθ = r/x
secθ = √74/-5
secθ = -√74/5
So, the exact value of secθ = -√74/5
The value of the trigonometric ratio cotθ
Since the trigonometric ratio cotθ = x/y
Substituting the values of x and y into the equation, we have
cotθ = x/y
cotθ = -5/-7
cotθ = 5/7
So, the exact value of cotθ = 5/7
