Answer: [tex]V = 24,416.64m^{3}[/tex]

Step-by-step explanation:

Solve for v  by simplifying both sides of the equation, then isolating the variable.

Formula: [tex]v = \frac{4}{3} \pi r^{3}[/tex]

Plugin the variable: [tex]v = \frac{3}{4}\pi (18^{3})[/tex]

Solve:

[tex]v = \frac{4}{3} 3.14 (5,832)[/tex]

Maggie made 3kg of fudge. She and her friends ate some and now there are 1 3/4 kg left. How many kg of fudge did maggie and her friends eat?

Answers

Answer:

1 1/4 kg

Step-by-step explanation:

Maggie made 3kg of fudge. She and her friends ate some and now there are 1 3/4 kg left. How many kg of fudge did maggie and her friends eat?

The kg of fudge thay maggie and her friends ate is calculated as:

Initial kg of fudge - kg of fudge left

= 3 kg - 1 3/4 kg

3/1 kg - 7/4 kg

Lowest common denominator = 4

= 12 - 7/4 kg

= 5/4 kg

= 1 1/4 kg

Lydia is playing Galaxy 8RX. After three misses, the game is over. Last week, Lydia kept track of how long her games lasted. Hse msde a line plot of her data. Lydia said,"My best time is 2 3/4 minutes longer than my worst time because 4 1/4-1 1/2=2 3/4. Is subtraction the correct operation to compare Lydia's best and worst times?Explain. Are Lydia's calculations accurate?Show how you know. In the line plot, what do the numbers Lydia subtracted represent? Does Lydia's conclusion make sense? How did you decide? If not, what can you do to improve her reasoning? ​

Answers

Answer:

Yes ; Yes ; Yes it makes sense

Step-by-step explanation:

1.) Lydia used subtraction operator to define and establish a relationship between her best and worst game times ; Hence we could conclude that Lydia is correct as this gives the range between both times.

From the numbers given in the question as their is no graph attached :

4 1/4 - 1 1/2

17/4 - 3/2

(17 - 6) / 4

11 /4

= 2 3/4

The subtracted numbers represent the duration of each of the three times game was played ; Hence the numbers represents the game times.

Yes ; Her conclusion makes sense ; as she was able to deduce the range between her best and worst game time

Answer:

Write - 11x^2 as a difference
x^4 - 4x^2 - 7x^2 + 28
Factor out x^2 from the expression
x^2 x (x^2 - 4) - 7x^2 + 28
Factor out - 7 from the expression
x^2 x (x^2 - 4) - 7 (x^2 - 4)
Factor out x^2 - 4 from the expression
(x^2 - 4) x (x^2 - 7)
Use a^2 - b^2= (a-b)(a+b) to factor the expression
(x-2) x (x + 2) x (x^2 - 7)
And that’s how it’s (x-2) x (x + 2) x (x^2 - 7) ..... yea and .-.

Answers

Answer: 3.9ft²

Step-by-step explanation:

Find the area of the rectangle first:

= Length * Width

= 2 * 1.5

= 3 ft²

Find the area of the semi-circle by finding the area of a circle and dividing it by 2:

= πr²

= 3.14 * 1.5/2 * 1.5/2

= 1.76625‬ft²

Divide by 2:

= 1.76625‬/ 2

= 0.88 ft²

Add the area of the rectangle to the semi-circle:

= 3 + 0.88

= 3.9ft²

3. What is the value of h?

Answers

Answer:

h=3

Step-by-step explanation:

(12-6)/(h--5)=3/4 ~ basic slope equation

6/(h+5)=3/4 ~ simplification

24=3(h+5) ~ multiply both sides by (h+5) and 4 to clear the fractions

24=3h+15 ~ distribute the 3

9=3h ~ subtract 15

h=3 ~ divide by 3

Answer:

Step-by-step explanation:

slope = -3

slope = (h-6)/(8-6) = (h-6)/2 = -3

h-6 = -6

h = 0

A local boys club sold 156 bags of mulch and made a total of $596. It sold two types of mulch: hardwood for $4.00 a bag and pine bark for $3.75 a bag. How many bags of each kind of mulch did it sell?

Answers

44 bags of hardwood, 112 bags of pine bark mulch.

we have two equations. I’ll call hardwood h, and pine bark p.

The number of bags: h + p = 156
The cost of the bags: 4h + 3.75p = 596

Start by solving the first equation for h in terms of p
h = 156 - p

Then substitute that in the other equation for h, and solve for a numerical value of p

4(156-p) + 3.75p = 596
624 -4p + 3.75p = 596
28 = 0.25p
p = 112

Now plug that in to the first equation to get the numerical value of h
h + p = 156
h + 112 = 156
h = 44

Check the math:
4(44) + 3.75(112)
176 + 420 = 596

pick the number that will make the following expression true.​

Answers

Step-by-step explanation:

If the cost of cereal is 35rand for 1 kg, this can be expressed as;

35 and = 1kg

To get the cost of 25grams, we can write

25g = x

0.025 kg  = x

Divide both expressions

35/0.025 = 1/x

35x = 0.025

x = 0.025/35

x = ​7.14*10^-4rand

Hence the cost of 25g is  ​7.14*10^-4rand

The mnemonic SOH CAH TOA reminds you of the relationships between sides and trig functions. The relevant relations here are ...

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

In your diagram, leg 'a' is opposite angle α and adjacent to angle β. Similarly, leg 'b' is opposite angle β and adjacent to angle α. The hypotenuse is 'c' in all cases.

So, filling the table is a matter of identifying adjacent and opposite legs. You will notice that the sine of α is the cosine of β and vice versa.
