Answer:
b=4 bills
Step-by-step explanation:
Let
b = number of bills received
a = number of adds received
l = number of letters received
m = number of magazines received
The Moore family received 27 pieces of mail, consisting of bills, ads, letters, and magazines:
b + a + l + m = 27
They received 3 more ads than letters:
a = l + 3
The same number of bills as letters:
b = l
5 more magazines than ads:
m = a + 5
Plug l = b into a = l + 3, we get: a = b + 3
Plug a = b + 3 into m = a + 5, we get: m = b + 3 + 5 that is m = b + 8
Now plug l = b, a = b + 3 and m = b + 8 into b + a + l + m = 27:
b + b + 3 + b + b + 8 = 27
evaluate the expression 3(x+4)- w when x=5and w =7
The expression 3(x+4)- w when x=5and w =7 can be evaluted by substituting x=5and w =7 in 3(x+4)- w.
\(undefined\)let x and y be i.i.d. unif(0, 1). (a) compute the covariance of x y and x y . (b) are x y and x y independent studysoup
If x and y be i.i.d. unif(0, 1), then the covariance of x + y and x - y is zero.
Yes, x y are x y independent studysoup.
Here x and y be i.i.d. unif(0, 1)
The i.i.d stands for independent and identically distributed
unif means that the uniformly distributed
Here x and y are i.i.d unif (0,1)
The covariance is defined as the relationship between the two random variables . Therefore, variance of one variable is equal to the change in another variable
Here we have to find the covariance of x + y and x - y
According to the properties of covariance
Cov(x+ y, x - y) = Cov (x, x) + Cov(y, x) - Cov(x, y) - Cov(y, y) = 0
Because Cov(x, x) = Cov (y, y)
Cov(y, x) = Cov(x, y)
Therefore, the covariance of x+y and x - y is 0.

There are 4 triangles with base of 5 and height of 8.4
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 5 x 8.4 = 21 m^2
Multiply by 4 = 21 x 4 = 84 m^2
Area of the base = length x width = 5 x 5 = 25 m^2
Total area = 84 + 25 = 109 m^2
logx+5 64 = 2
Please help!!
Solve and round to the nearest 100th
Explain how
WILL GIVE BRAINIEST FIRST ANSWER
The left-hand side of the equation represents the logarithm of 64 with base x, and it is not possible to find a real value of x that satisfies the equation.
solve the equation logₓ(64) + 5 = 2, we can follow these steps:
Step 1: Move the constant term to the other side of the equation:
logₓ(64) = 2 - 5
logₓ(64) = -3
Step 2: Rewrite the equation in exponential form:
x^(-3) = 64
Step 3: Rewrite 64 as a power of x:
x^(-3) = x^6
Step 4: Set the exponents equal to each other:
-3 = 6
The equation -3 = 6 is not true, which means there is no real solution to the given equation.
Therefore, the equation logₓ(64) + 5 = 2 has no solution in the real number system.

You buy 3.18 pounds of oranges, 1.25 pounds of peaches, and 1.96 pounds of grapes. What is your total bill
Answer:
$6.39
Step-by-step explanation:
Just add the cost of everything
3.18 + 1.25 + 1.96 = 6.39
Answer:
total bill= 6.40
Step-by-step explanation:
You buy 3.17 pounds of apples, 1.25 pounds of pears, and 2.56 pounds of oranges.
Total bill = 3.18 + 1.25 +1.96 = 6.39
Total bill = 6.39 pounds.
We can see the number after the decimal is greater than 5 so the number would be increased by 1.
Total bill = 6.40 pounds .

2m+8m=27+13
10m=40
m=40÷10
Therefore, m=4
Answer:
2m - 13 = -8m +27
2m + 8m = 27 + 13
10m = 40
m = 4
15. Math. The poissonier receives 30 lb.. 4 oz. of
dressed mahi-mahi. After filleting and skinning.
13 lb.. 12 oz. of fillets were produced. What
is the yield percentage of the fillets? If the
whole dressed mahi-mahi was purchased
for $5.85/b.. what is the per pound cost of
the fillets?
Answer:
To find the yield percentage of the fillets, we need to divide the weight of the fillets by the weight of the dressed mahi-mahi and then multiply by 100 to get a percentage:
Yield percentage = (Weight of fillets / Weight of dressed mahi-mahi) x 100%
First, we need to convert the weights to a common unit, such as ounces:
Weight of dressed mahi-mahi = 30 lb. 4 oz. = 484 oz.
Weight of fillets = 13 lb. 12 oz. = 220 oz.
Now we can calculate the yield percentage:
Yield percentage = (220 oz. / 484 oz.) x 100% = 45.45%
So the yield percentage of the fillets is 45.45%.
To find the per pound cost of the fillets, we need to divide the total cost of the dressed mahi-mahi by its weight in pounds, and then multiply by the yield percentage to get the cost per pound of fillets:
Total cost of dressed mahi-mahi = 30.25 lb. x $5.85/b. = $176.96
Weight of dressed mahi-mahi in pounds = 30.25 lb.
Weight of fillets in pounds = 13.75 lb.
Cost per pound of fillets = (Total cost of dressed mahi-mahi / Weight of dressed mahi-mahi) x Yield percentage / 100%
Cost per pound of fillets = ($176.96 / 30.25 lb.) x 45.45% = $3.04/lb.
Therefore, the per pound cost of the fillets is $3.04/lb.
Which of the following conditions are sufficient to show that triangle ABC sim triangle QPR
Select all that apply.
A. m angle Q = 63
B. m angle R = 81
D. m angle P = 81
C. RP = 4.5
Answer:
C. RP = 4.5
Step-by-step explanation:
You want to know what condition is sufficient to show ∆ABC ~ ∆QPR, given three sides and 2 angles in ∆ABC, and 2 sides in ∆QPR.
SimilaritySimilarity can be shown if all three sides are proportional, or if two angles are congruent.
The offered answer choices only list one angle, so none of those will work. The answer choice that makes the third side of ∆QPR be in the same proportion as the corresponding side of ∆ABC is the condition of interest.
C. RP = 4.5
__
Additional comment
The side ratios in the two triangles are ...
AB : BC : CA = 10 : 9 : 6
QP : PR : RQ = 5 : PR : 3
For these ratios to be the same, PR must be half of BC, just as the other segments in ∆QPR are half their counterparts in ∆ABC.

A large box holds twice as many chocolates as a medium box and three times as many chocolates as a small box. Noor fills three times as many small boxes as medium boxes and twice as many medium boxes as large boxes. Altogether she packs 1296 chocolates. In total, how many chocolates does she pack into the small boxes.
The number of chocolate which goes into the small boxes is 100 chocolate
EquationChocolate in small boxes = xChocolate in medium boxes = 3xChocolate in large boxes = 3x + 2(3x)= 3x + 6x

A dance team decided to sell fruit snacks to raise money for an upcoming competition. The dancers charged $3.00 for each fruit snack they sold. In 4 days, they sold 24 packs of fruit snacks. How much money could the team earn for seven days at that same rate?
Answer:
126 dollars
Step-by-step explanation:
(i'm gonna be doing my work here, dont mind me LOL)
okay, so they sold 24 packs in 4 days. divide 24 by 4 and you get 6. multiply 6 by 3 and you get 18.
now, multiply 18 by seven and you get 126.
bam!! the dance team could earn 126$ in 7 days ^__^ hope you get an A!
Answer:
$126
Step-by-step explanation:
Let x = packs sold in 7 days
Set up a proportion. days/days = packs/packs
4/7 = 24/x
4x = 24(7) = 42 packs sold in 7 days
At $3/pack, the amount earned in 7 days = 3(42) = $126
