A store is having a sale on almonds and jelly beans. For 7lb of almonds and 9 lb of jelly beans, the total cost is $51. For 5 lb of almonds and 3 lb of jelly beans, the total cost is $27. Find the cost for each pound of almonds in each pound of jelly beans.
Answer:
the cost for each pound of almonds in each pound of jelly beans is $3.75 and $2.75 respectively
Step-by-step explanation:
The computation is shown below:
Let us assume the almons be x
And the jelly beans be y
Now the first equation would be
7x + 9y = $51
And, the second equation is
5x + 3y = $27
Now multiplied by 5 and 7 in equation 1 and 2
35x + 45y = $255
35x + 21y = $189
24y = 66
y = $2.75
Now put the y value in any one of the equation
7x + 9($2.75) = $51
7x + $24.75 = $51
7x = $51 - $24.75
7x = $26.25
x = $3.75
Hence, the cost for each pound of almonds in each pound of jelly beans is $3.75 and $2.75 respectively

Answer:
B
Step-by-step explanation:
You would need to convert the fractions to a denominator of 15 because it's the closest denominator for both.
So 1 and 2/5 can be changed to 1 and 6/15
And 1 and 1/3 can be changed to 5/15
So what you do is multiply both the numerator and denominator by how much you need to multiply to get to 15 and the denominator.
You would then add the fractions, leaving the answer to be 2 and 11/15
So for example 2 * 3 = 6 and 5 * 3 = 15, meaning the fraction would be 6/15

find the value of x to the nearest tenth
Answer:
x = 41.2
Step-by-step explanation:
Assuming the dotted line at the top is parallel to the segment with length x, it follows from the alternate interior angles theorem that the interior angle of the triangle (marked in diagram) is also 27º.
Using SOH-CAH-TOA, we get that tan(27º) = 21/x, so x = 21/tan(27º), which is approximately equal to 41.2.

1. First, think about how much salad dressing the recipe makes if you mix together 14 c lemon juice, 18 c mustard, and 14 c vinegar:
2. Next, think about how much lemon juice you will need for 1 cup of salad dressing:
3. Finally, use what you found in part 2 to find out how much lemon juice you will need for 4 cups of salad dressing:
Answer:
He needs 56c of lemon juice to make 4 salad dressings.
Step-by-step explanation:
We only need to look at how much lemon juice to make one salad dressing which would be 14c so we have to make 4 so we would do 14x4 to get how much lemon juice you need to make 4 dressings so you would need 56c of lemon juice to make 4 dressings

Is the length of DE is shown, what other length can you determine for this diagram? Help me please
Answer:
Another length of this diagram FE=12.
Step-by-step explanation:
According to diagram
In triangle FED, EM is perpendicular bisector of FD.
In ΔFED, EM ⊥ FD and FM=MD
In ΔFME and ΔDME
FM=DM (Given)
∠FME=∠DME (each 90°)
ME=ME (Common)
ΔFME ≅ ΔDME (By SAS congruence property)
Therefore, FE≅DE (by CPCT)
But DE=12
So, FE=12
Thus, Another length of this diagram FE=12.

A student has a penny, nickel, dime, and a quarter. She flips them all simultaneously and checks for heads or tails. What is the probability that all four coins will come up heads
Answer:
1/ 16
Step-by-step explanation:
Flipping a coin = HT ( 2 possibilities)
Hence, total possibility (n) of flipping 4 coins
n = 2^4 = 2 * 2 * 2 * 2 = 16 possible outcomes
(HHHH, THHH, HHHT, THHT, HHTH, THTH, HHTT, THTT, HTHH, TTHH, HTHT, TTHT, HTTH TTTH, HTTT, TTTT
Probability (A) = required outcomes of A / total possible outcomes
Hence, probability that all coins comes up head :
Number of required outcome = 1
Total possible outcomes = 16
Hence,
P(all heads) = 1/16
Using the binomial distribution, it is found that there is a 0.0625 = 6.25% probability that all four coins will come up heads.
For each coin, there are only two possible outcomes, either it is heads, or tails. The outcome of each coin is independent of other coins, hence, the binomial distribution is used to solve this question.
What is the binomial probability distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
A coin is equally as likely to come heads or tails, hence [tex]p = 0.5[/tex].The student has 4 coins, hence [tex]n = 4[/tex].The probability that all four coins will come up heads is P(X = 4), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 4) = C_{4,4}.(0.5)^{4}.(0.5)^{0} = 0.0625[/tex]
0.0625 = 6.25% probability that all four coins will come up heads.
