Answer:
[tex]5\frac{23}{64}\approx 5.36 [/tex] cubic meters.
Step-by-step explanation:
We have been given that the surface area of a cube is [tex]18\frac{3}{8}[/tex] square meters and we are asked to find the volume of the cube.
Since we know that surface area of a cube with each edge equals a units is:
[tex]\text{Total surface area of cube}=6a^2[/tex]
Let us find length of each edge using surface area formula.
[tex]18\frac{3}{8}=6a^2[/tex]
Let us convert our given area into mixed fraction.
[tex]\frac{147}{8}=6a^2[/tex]
Upon dividing both sides of our equation by 6 we will get,
[tex]\frac{147}{8*6}=a^2[/tex]
[tex]\frac{147}{48}=a^2[/tex]
Upon taking square root of both sides we will get,
[tex]\frac{7\sqrt{3}}{4\sqrt{3}}=a[/tex]
[tex]\frac{7}{4}=a[/tex]
Now we will use volume of cube formula with each side length 'a'.
[tex]\text{Volume of cube}=a^3[/tex]
[tex]\text{Volume of cube}=(\frac{7}{4})^3[/tex]
[tex]\text{Volume of cube}=\frac{343}{64}[/tex]
[tex]\text{Volume of cube}=5\frac{23}{64}[/tex]
[tex]\text{Volume of cube}=5.359375\approx 5.36[/tex]
Therefore, the volume of cube will be [tex]5\frac{23}{64}[/tex] cubic meters.
Solve h + p = 4(k − 8) for k.
Answer:
[tex]\frac{h+p+32}{4}[/tex]
Step-by-step explanation:
distribute the parenthesis
h + p = 4k - 32 ( isolate 4k by adding 32 to both sides )
h + p + 32 = 4k ( divide both sides by 4 )
k = [tex]\frac{h+p+32}{4}[/tex]
expand the brackets, to get 4k-32
sp you have; h + p = 4k - 32
add 32 to both sides== h + p + 32 = 4k
/4
k= (h + p+ 32)/4

Answer: 40 ounces=2.5 pounds
Step-by-step explanation:
Since 1 pound=16 ounces. You have to see how many times 16 goes into 40, it goes in forty 2 times with 8 left over so that means we need decimal, since 8 is half of 16 the answer is 2.5.
Final answer:
To convert 40 ounces of meat to pounds, divide by the unit equivalence of 16 ounces per pound, resulting in 2.5 pounds of meat needed for the recipe.
Explanation:
The student is asking how many pounds are equivalent to 40 ounces of meat. To find the answer, you will need to know the unit equivalence between ounces and pounds.
The unit equivalence is 1 pound = 16 ounces. Therefore, to convert ounces to pounds, you divide the number of ounces by the unit equivalence.
Converting 40 ounces to pounds:
Start with the given amount in ounces: 40 ounces.Use the unit equivalence: 1 pound = 16 ounces.Divide 40 ounces by 16 ounces per pound to find the number of pounds.40 ounces ÷ 16 ounces/pound = 2.5 pounds
So, the recipe requires 2.5 pounds of meat.

Which value is the same as 2 tenths?
2 tenths is equal to 0.2 in decimal format. This is derived from its fraction format, 2/10, and its place value in the base-ten number system, which is a 'tenths' place.
Explanation:In mathematics, the value that is equivalent to 2 tenths is 0.2. This is because when we say 'tenths', we are referring to a fractional or decimal value that has a denominator of ten in the context of fractions or one place after the decimal point.
Therefore, 2 tenths is essentially 2 divided by 10 which equals 0.2 in decimal format. We can further illustrate this using a base-ten number system. In this system, each place to the right of the decimal point represents a 'tenths' place value. Therefore, in the number 0.2, the digit '2' is in the 'tenths' place.

A recursive rule for an arithmetic sequence is a1=-2; an=an-1 -9
What is an explicit rule for this sequence?
The explicit rule for the given arithmetic sequence is an = -2 + (n - 1) * (-9)
Explanation:An arithmetic sequence is a sequence of numbers in which each term is found by adding a common difference to the previous term. In this case, the recursive rule for the arithmetic sequence is given as a1 = -2 and an = an-1 - 9.
To find the explicit rule for this sequence, we need to find a formula that directly calculates the nth term of the sequence. We can do this by examining the pattern in the sequence:
First term: a1 = -2Second term: a2 = a1 - 9 = -2 - 9 = -11Third term: a3 = a2 - 9 = -11 - 9 = -20Fourth term: a4 = a3 - 9 = -20 - 9 = -29...From the pattern, we can see that each term is obtained by subtracting 9 from the previous term. So, the explicit rule for this arithmetic sequence is given by:
an = a1 + (n - 1) * d
where a1 is the first term, n is the term number, and d is the common difference. Plugging in the values, we have:
an = -2 + (n - 1) * (-9)
Simplifying this equation gives the explicit rule for the sequence.
Final answer:
The explicit rule for the arithmetic sequence is an = -2 + (n-1)(-9).
Explanation:
An explicit rule for an arithmetic sequence is given by the formula:
an = a1 + (n-1)d
Where:
an is the nth term of the sequence
a1 is the first term of the sequence
n is the position of the term in the sequence
d is the common difference between consecutive terms
In this case, the first term (a1) is -2 and the common difference (d) is -9. Therefore, the explicit rule for this sequence is:
an = -2 + (n-1)(-9)

Dan wants to make 12 pancakes but what quantity of each ingredient should he use for 240g plain flour,2 eggs and 600ml milk?
To make 12 pancakes, Dan should use 20g of plain flour, 2 eggs, and 50ml of milk.
Explanation:To determine the quantity of each ingredient needed to make 12 pancakes, we can use the ratio of ingredients given in the recipe:
240g plain flour : 2 eggs : 600ml milk
To find the quantity of plain flour needed for 12 pancakes, we can set up a proportion:
240g / x = 12 / 1
Cross multiplying, we get:
x = (240g * 1) / 12
x = 20g
Therefore, Dan should use 20g of plain flour for 12 pancakes. Similarly, he should use 2 eggs and 50ml of milk for 12 pancakes.

Julia is allowed to watch no more than 5 hours of telivison a week. So far this week, she has watched 1.5 hours. write and solve an inequality to show how many hours of teli she can watch this week. ( can u show your work along with it? )
Answer:
she can watch 3.5 hours this week.
Step-by-step explanation:
Julia is allowed to watch no more than 5 hours of television a week.
Let x be the number of hours she can watch per week
number of hours not more than 5 hours
so x<=5
She already watched 1.5 hours. so inequality becomes
x+ 1.5 <= 5
Now we solve for x
subtract 1.5 on both sides
x + 1.5 < = 5 - 1.5
x < = 3.5
So, she can watch 3.5 hours this week.

there are 11 regular players and 5 substitute players on a soccer team how many players are on 15 soccer teams ??
Answer:
225 players (including the substitutes)
Step-by-step explanation:
11 regular player and 4 substitutes makes 15 team members per team.
15 players on each team times 15 teams gives you 225 players in total.
The total number of players on 15 soccer teams can be calculated by multiplying the total number of players (including regular and substitute) on one team (16 players) by the number of teams (15), which equals 240 players.
Explanation:The subject of this question is Mathematics, and it's referencing a concept of multiplication in a real-world context. To determine the total number of players on 15 soccer teams, you consider that each team is composed of 11 regular players and 5 substitutes. So, the total number of players on one team is 16 (11 regular players + 5 substitutes).
To find out the number of players on 15 teams, you multiply the number of players on one team by 15. That is, 16 players * 15 teams = 240 players. So, there are 240 players on 15 soccer teams.

Which of the following would earn the same amount of interest as a $600 principal with 2.5% interest for 6 years?
To earn the same amount of simple interest as $600 with 2.5% interest over six years ($90), another investment combination that would yield the same interest amount is $1,000 at 3% interest for 3 years.
Explanation:The student is asking which investment would earn the same amount of simple interest as a principal of $600 with 2.5% interest over 6 years. The formula for calculating simple interest is Interest = Principal imes Rate imes Time. For the given principal of $600 with 2.5% interest over 6 years, the interest earned would be:
Interest = $600 imes 0.025 imes 6
Interest = $90
To find another investment with the same interest earned, one must find a principal, rate, and time that satisfy the equation:
Interest Earned = New Principal imes New Rate imes New Time = $90
An example would be a principal of $1,000 with 3% interest for 3 years:
Interest Earned = $1,000 imes 0.03 imes 3
Interest Earned = $90
This indicates that both investments would earn the same amount of interest over their respective periods.
Given g(x)=3x+5, find g(-6)
g(-6) This means that x = -6, so you can plug in -6 for "x" in the equation

g(-6) = -18 + 5
g(-6) = -13
To find g(-6), substitute -6 into the given function and simplify the expression.
Explanation:To find g(-6), we substitute -6 into the given function, g(x) = 3x+5.
So, g(-6) = 3*(-6) + 5
g(-6) = -18 + 5
g(-6) = -13

Anyone know? Will mark brainliest if correct!
The answer is A. g(x).
Here's why:
f(x) = -x^4 - 2: This function is a downward-facing parabola (due to the negative coefficient of x^4) with a maximum y-value at its vertex. The vertex occurs at x = 0, and the maximum y-value is f(0) = -2.
g(x) = -3x^3 + 2: This function is a cubic function with a local maximum, but it does not have a global maximum. However, its maximum value is still greater than the maximum value of f(x).
Key points:
The maximum y-value of f(x) is limited to -2 because of the negative leading coefficient and the constant term of -2.
g(x) doesn't have a defined maximum y-value, but it can reach values greater than -2, making its maximum value larger than that of f(x).
Therefore, g(x) has the largest maximum y-value among the two functions.

Jasmine practices the piano for 10 minutes on Monday. Every day she increases her practice time by 5. If she continues this pattern, how many minutes will she practice on the 7th day?
Answer:
40 minutes
Step-by-step explanation:
Day 1) Monday --> 10 min.
Day 2) Tuesday --> 15 min.
Day 3) Wednesday --> 20 min.
Day 4 )Thursday --> 25 min.
Day 5) Friday --> 30 min.
Day 6) Saturday --> 35 min.
Day 7) Sunday --> 40 min.
Using the formula for the nth term in an arithmetic sequence, we find that Jasmine will practice for 40 minutes on the 7th day.
Explanation:The problem can be solved by using arithmetic progression. The first term of this sequence is the amount of time Jasmine spent practicing on Monday, which is 10 minutes. The common difference is the amount of time she adds to her practice every day, which is 5 minutes. To find out how long she will practice on the 7th day, we can use the formula for the nth term in an arithmetic sequence: a + (n-1)d.
Plugging in our values, we find:
10 + (7-1)*5 = 10 + 30 = 40.
So, Jasmine will practice for 40 minutes on the 7th day.
