Laurie is not correct because, the 3 bags of topsoil is less than 40 pounds. The correct option is - D.Laurie is not correct because the weight of 3 bags of topsoil is less than 40 pounds.
Weight & ConversionFrom the question, we are to determine if Larie is correct or not
From the given information,
Laurie needs at least 40 pounds of topsoil.
Then,
If she buys 3 bags of topsoil that weigh 200 ounces each, she will get 600 ounces of topsoil.
Now, convert 600 ounces to pounds
NOTE: 16 ounces = 1 pound
Then,
600 ounces = (600/16) pounds
600 ounces = 37.5 pounds
Hence, the 3 bags of topsoil will weigh 37.5 pounds of topsoil.
Since, Laurie needs at least 40 pounds of topsoil, then Laurie is not correct because, the 3 bags of topsoil is less than 40 pounds. The correct option is - D.Laurie is not correct because the weight of 3 bags of topsoil is less than 40 pounds.

F(x) = 5x -3 solve for f(5)
Answer:
22
Step-by-step explanation:
f(x)=5x-3
f(x)=5(5)-3
f(x)=25-3
f(x)=22
Answer:
[tex]f(5)=22[/tex]
Step-by-step explanation:
since the function is f(x), then you would plug in the 5 since that is x value that is being given then it would be [tex]f(5)=5(5)-3[/tex]. from there multiply 5 and 5 to get 25 then subtract 3 to get 22.

-[tex]\frac{10}{1}[/tex]Answer:
lydia's answer is correct.
Step-by-step explanation
4/5 X 10=8 because
[tex]\frac{4}{5}[/tex] X [tex]\frac{10}{1}[/tex] -->we do the denominator first so 5 x 1 = 5 so now it's
[tex]\frac{4}{5}[/tex] [tex]\frac{10}{5}[/tex] so 4 X 10= 2 x 5(we replace 10 with that ) over 5 and the you will be left with 4 x 2 over 5 that is because 5 and 5 canceled out so
now you're left with this 4 x 2 = 8 so 8 is you final answer without the fraction :) hope this helps

A storage tank is 20% filled with water. The storage tank holds, 1,160 gallons of water. How many gallons of water are needed to fill the storage tank to the top?
The storage tank requires an additional 4,640 gallons of water to be filled to the top, calculated by finding the total tank capacity using the 20% already filled and subtracting the current water volume.
The student asks about the amount of water needed to fill a storage tank to the top given that the tank is already 20% full with 1,160 gallons of water. To find out how much more water is required, we first need to establish the total capacity of the tank.
Since 1,160 gallons represent 20% of the tank's capacity, we can calculate the full capacity by dividing the amount of water currently in the tank by 0.2. After finding that number, we need to subtract 1,160 from the total capacity to find the amount of water needed to fill the tank.
Calculation:
1. Calculate the full capacity of the tank:
Total capacity = 1,160 gallons / 0.20 = 5,800 gallons.
2. Calculate the gallons of water needed to fill the tank:
Gallons needed = Total capacity - Current amount of water
Gallons needed = 5,800 gallons - 1,160 gallons = 4,640 gallons.
Therefore, 4,640 gallons of water are needed to fill the storage tank to the top.

(08.05)Theresa earned scores of 88 points, 84 points, 88 points, and 91 points on four tests. What is the lowest score she can get on the fifth test and still finish with an average score of 90 points?
96 points
97 points
98 points
99 points
Answer: D) 99 Points
Step-by-step explanation: Theresa earned scores of 88 points, 84 points, 88 points, and 91 points on four tests
Therefore the totals points are 351
351 is her total score for 4 tests, if she gets an average score of 90 on her fifth test then all we have to do is:
5 x 90 = 450 (The 5 being her fifth test)
450-351 = 99

To simplify the given expression, we first simplify the fraction within the square root, performing the division of similar bases by subtracting exponents. Then, we take the square root of 64 to get 8 and obtain the final simplified expression: 8/x^2y.
Explanation:To solve the specific expression, equivalent to StartRoot StartFraction 128 x Superscript 5 Baseline y Superscript 6 Baseline Over 2 x Superscript 7 Baseline y Superscript 5 Baseline EndFraction EndRoot, we will start by simplification inside the square root bracket. Perform the division with the fractions first. As a general rule, when dividing powers with the same base, we subtract the powers.
We'll start by simplifying 128/2, which is 64. For x Superscript 5 Baseline / x Superscript 7 Baseline, subtract the exponents, which gives us x to the power of -2 (since 5-7 is -2). For y Superscript 6 Baseline / y Superscript 5 Baseline, we also subtract the exponents, which results in y to the power of 1, or simply y.
Hence, the simplified version of the fraction inside the square root is 64x^-2y. Finally, since the square root of 64 is 8, and the square root of any variable raised to the negative power is the reciprocal of the variable, our final simplified expression is 8/x^2y.

A scientist needs 120 ML of a 20% acid solution for an experiment. The lab has available at 10% solution and a 25% solution. How many milliliters of the 10% solution and how many milliliters of a 25% solution should the scientist mix to make the 20% solution?
Answer:
40 milliliters of the 10% solution and 80 milliliters of the 25% solution the scientist should mix to make the 20% solution.
Step-by-step explanation:
Given:
A scientist needs 120 ML of a 20% acid solution for an experiment. The lab has available at 10% solution and a 25% solution.
Now, to find the milliliters of 10% solution and 25% solution to make 20% solution:
Let the 10% solution be [tex]x.[/tex]
And let the 25% solution be [tex]y.[/tex]
So, total milliliters of solution are:
[tex]x+y=120\\\\x=120-y\ \ \ \ .....(1)[/tex]
Now, to get the milliliters of 10% solution and 25% solution to make 20% solution we solve the equation:
[tex]10\%\ of\ x+25\%\ of\ y=20\%\ of\ 120\\\\\frac{10}{100} \times x+\frac{25}{100} \times y=\frac{20}{100} \times 120\\\\0.10x+0.25y=24[/tex]
Substituting the value of [tex]x[/tex] from equation (1) we get:
[tex]0.10(120-y)+0.25y=24\\\\12-0.10y+0.25y=24\\\\12+0.15y=24[/tex]
Subtracting both sides by 12 we get:
[tex]0.15y=12[/tex]
Dividing both sides by 0.15 we get:
[tex]y=80.[/tex]
Thus, the 25% solution is 80 ml.
Now, substituting the value of [tex]y[/tex] in equation (1) we get:
[tex]x=120-y\\\\x=120-80\\\\x=40\ ml.[/tex]
Hence, the 10% solution is 40 ml.
Therefore, 40 milliliters of the 10% solution and 80 milliliters of the 25% solution the scientist should mix to make the 20% solution.
A construction manager weighs a bundle of 9 identical bricks and a 7 pound concrete block. The bundle weighs 30 pounds.
Answer:
30 = 9x + 7
Step-by-step explanation:
The total weight of the bundle = 30 pounds
The weight of the bricks = x pounds
But he carried 9 bricks = 9x pounds
He also carried additional 7 pounds of concrete block.
An equation to show the total weight he carried is
30 pounds = (9x + 7) pounds
Since 9x represents the total weight of the bricks he carried
7 represents the weight of the concrete block
And 30 pounds represents the total weight of everything he carried.
Suppose Theta is an angle in standard position whose terminal side lies in
Quadrant 3. If sine--12/13, find the value of tan Theta
A. -12/5
B. 13/5
C. 5/12
D. 12/5
The correct answer is tan Theta = 12/5.
The task is to find the value of tan Theta given that in a position where its terminal side lies in Quadrant 3 and sine is -12/13. In the third quadrant, both sine and tangent are negative, so we expect a negative ratio for tan Theta. Since sine equals opposite over hypotenuse, we have:
sin Theta = opposite/hypotenuse = -12/13
The negative sign indicates that the opposite side is in the negative direction (downward in this case).
To find tan Theta, we'll use the Pythagorean theorem to find the length of the adjacent side:
opposite^2 + adjacent^2 = hypotenuse^2
(-12)^2 + adjacent^2 = 13^2
144 + adjacent^2 = 169
adjacent^2 = 169 - 144
adjacent^2 = 25
adjacent = [tex]\sqrt{5}[/tex]
Because we're in the third quadrant, where the x-coordinate (adjacent side in the context of the unit circle) is negative, adjacent = -5.
Now, tan Theta = opposite/adjacent = -12/-5 = 12/5.
Therefore, the correct answer is D. 12/5.
