Answer:
30% of the meat on the platter is ham.
Step-by-step explanation:
90 slices = 100%
10% = 9 slices
90 - 63 = 27 slices (this is the amount of ham)
10% x 3 = 30% = 27 slices of ham
Answer:
27 slices of ham which is about 30% of the meat.
Step-by-step explanation:
In this problem we have given
no. of slices of meat=90
no of slices of turkey's meat=63
Percent of ham in platter=?
No of ham slices= Total slices -turkey slices
=90 - 63
= 27 slices
therefore no of ham slices=27
percent of ham slices=Ham slicesx100/total slices
=27x100/90%
=30%
Therefore percent of ham's in patter=30%
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.

There are 96 coins in a bottle. 1\2 of the coins are £1 coins. The rest of the coins are 50p coins. work out the total value of the 96 coins I need help with this
Answer:
£72
Step-by-step explanation:
Firstly, if half of 96 coins are £1 coins then:
96/2 * 1 = value of half the coins = £48
Now, we simply need to multiply 96/2 by 0.5 to find the value of these coins:
48 * 0.5 = 24
Now we can add the two:
48 + 24 = 72
So the value of the 96 coins are £72.

Yesterday, Julie’s bank account balance was $39.99. Today, she made a withdrawal from her account. The current balance is –$10.28.
How much did she withdraw from her account?
A). $50.27
B). $29.71
C). $0.00
D). $19.61
Answer:
A). $50.27
Step-by-step explanation:
Add $39.99 and -$10.28 to get $50.27
Final answer:
Julie withdrew $50.27 from her account, which can be calculated by adding her previous balance of $39.99 to the absolute value of her negative current balance, $10.28.
Explanation:
The question asks to determine how much was withdrawn from Julie's bank account, given that her balance went from $39.99 to -$10.28. To do this, we subtract the current balance from the previous balance. So the calculation is $39.99 - (-$10.28).
First, subtracting a negative is the same as adding its absolute value, so the equation can be rewritten as $39.99 + $10.28.
When these two values are added together, we get a total of $50.27. This means that Julie withdrew $50.27 from her account.
Therefore, the correct answer is A). $50.27.
what type of green paint is made by mixing 2 cups of yellow with 3.5 cups of blue a.find a mixture that will make the same shade of green but a smaller amount
Answer:
Step-by-step explanation:
We are given that a shade of green is prepared using 2 cups of yellow and 3.5 cups of blue.
We want to make the same shade of green, but lesser quantity. We can assume a smaller value for either of the yellow or the blue colors, and find the corresponding value of the other to figure out the answer.
Let us assume that 1 cup of yellow is mixed with x cups of blue to prepare the same shade of the green. Now we can set up the ratios as shown below:
[tex]\frac{1}{x}=\frac{2}{3.5}\\2x=3.5\\x=1.75[/tex]
Therefore, 1 cup of yellow and 1.75 cups of blue color will also make the same shade of green

Determine ‘a’ and ‘d’ for t7= 3 + 5x and t11= 3 + 23x (formula is tn= a + (n-1) x d)
(25 POINTS!!)
Final answer:
To determine 'a' and 'd' for tn = a + (n-1)x, substitute the values of 'n' and 't' into the equations and solve the system of equations.
Explanation:
To determine 'a' and 'd' for tn = a + (n-1)x, we need to find the values of 'a' and 'd' that satisfy both t7 = 3 + 5x and t11 = 3 + 23x.
Step 1: Set up two equations
t7 = 3 + 5x
t11 = 3 + 23x
Step 2: Use the formula tn = a + (n-1)x to substitute the values of 'n' and 't' in the equations.
a + 6d = 3 + 5x (equation 1)
a + 10d = 3 + 23x (equation 2)
Step 3: Solve the system of equations.
Subtract equation 1 from equation 2: (a + 10d) - (a + 6d) = (3 + 23x) - (3 + 5x)
Cancel out the 'a' terms and simplify the 'd' and 'x' terms: 4d = 18x
Divide both sides by 18: d = 4.5x
Substitute the value of 'd' in equation 1 to solve for 'a': a + 6(4.5x) = 3 + 5x
Expand and simplify the equation: a + 27x = 3 + 5x
Subtract 5x from both sides: a + 22x = 3
Subtract 22x from both sides: a = 3 - 22x
So, the values of 'a' and 'd' are a = 3 - 22x and d = 4.5x.

g(-6) This means that x = -6, so you can plug in -6 for "x" in the equation
g(x) = 3x + 5
g(-6) = 3(-6) + 5
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

Enzel goes online to buy a graphing calculator. He finds a site that currently has a promotion of 15% off on all orders over $50. Enzel decides to buy his graphing calculator, with a price tag of $83, at this site because he knows that he will get the 15% discount when he checks out. Enzel pays 4.5% sales tax on the discounted price and pays a shipping fee of $6.35. What is the total of Enzel’s online purchase?
So firstly, we need to find the discounted price. Since this is going to be a decrease by percentage, we will be using this format:
(1 - p)m(p = percentage in decimal form and m = original price)In this case:
[tex]15\% = 0.15\\\\(1-0.15)*83\\0.85*83\\70.55[/tex]
Now that we have the discounted price, we must apply the 4.5% sales tax. Since this is going to be an increase by percentage, we will be using this format:
(1 + p)mIn this case:
[tex]4.5\%=0.045\\\\(1+0.045)*73.55\\1.045*70.55\\73.72[/tex]
Now we have the discounted price with the sales tax. Now all we have to do is add the shipping fee:
[tex]73.72+6.35=80.07[/tex]

According to the manufacturer, about 26% of sour candy in a package of Sandy's Sours are grape. What is the probability that the first grape candy chosen from the bag will be, at LEAST, the third candy chosen overall?
To find the probability that the first grape candy chosen from the bag will be, at least, the third candy chosen overall, you multiply the probability that a candy is not grape (0.74) by itself (since we're considering two independent events, both candies not being grape). The answer is 0.5476.
Explanation:The subject of this question is probability which is a branch of mathematics. You're looking to find the probability that the first grape candy drawn from a bag of Sandy's Sours will be, at least, the third candy chosen overall.
Given that 26% of the candies are grape, the probability that the first candy drawn is not grape is 1 - 0.26 = 0.74 (or 74%). Since we're looking for the first grape candy to be the third candy drawn or later, we need the first two candies to be not grape.
The probability that the first candy drawn is not grape is 0.74. Because each candy draw is an independent event (the result of one draw does not affect the results of any other draws), the probability that neither the first nor the second candy drawn is grape is 0.74 * 0.74 = 0.5476 (or 54.76%).

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.

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)
