Shelby sold 75 raffle tickets for the school fundraiser over a 3-year period. If Kelly sold 15 less tickets than Shelby over the last 3 years, how many did Kelly sell each year on average?
Answer: 20 tickets
Step-by-step explanation:
From the question, we are informed that Shelby sold 75 raffle tickets for the school fundraiser over a 3-year period while Kelly sold 15 less tickets than Shelby. This means that the number of tickets sold by Kelly is:
= 75 - 15
= 60 tickets
The number of tickets sold by Kelly each year on average will be:
= Number of tickets sold / Number of years.
= 60/3.
= 20 tickets
over the last 3 years
what is x?
-5 (x - 1) = 40
Answer:
x= -7
Step-by-step explanation:
have a good day
Step-by-step explanation:
- 5 (x - 1) = 40(Multiply -5 by the values in the bracket)
-5x + 5 = 40(Subtract 5 on both sides)
-5x = 40 - 5
-5x = 35 (Divide both sides by -5)
x=-7

Scientists bounce a laser beam off a mirror. It reflects at the same angle as it hits the
mirror and is detected by an instrument several inches away.
Calculate the total distance of the laser beam travels. Round to the nearest tenth if necessary.
Answer and Step-by-step explanation:
Simply use triangles to find the length of the lasers.
The first triangle consists of the sides of 12 inches, 18 inches, and the laser (which is the hypotenuse).
Use the Pythagorean theorem to solve for the hypotenuse.
([tex]a^{2}+ b^{2} = c^{2}[/tex])
[tex]12^{2} +18^{2} = l^{2} \\\\144 + 324 = l^{2} \\\\468 = l^{2} \\\\Square-root-both-sides\\\\\ \\\sqrt{468} = l[/tex]
l ≈21.633
Now, we solve the other triangle.
[tex]9^{2} +6^{2} = l^{2} \\\\81 + 36 = l^{2} \\\\117 = l^{2} \\\\Square-root-both-sides\\\\\sqrt{117} =l\\l = 10.8167[/tex]
Now, add those two hypotenuses.
21.6333 + 10.8167 = 32.45
32.45 rounds up to 32.5
32.5 is the total distance the laser beam travels.

Consider this quadratic equation:
2x2+1x+3=0
Comparing it to the standard form, name a, b, and c
a=
b=
C=
Explanation: The value for a comes from the coefficient
on the x² term which in this case is 2 so we say that a = 2.
The value for b comes from the coefficient on the x term
which in this case is 1 so we say that b = 1.
The value for c comes from the constant term
which in this case is 3 so we say that c = 3.

7/9 * 10/9 * 0.62 =
(7 * 10 * 62) / (9 * 9 * 100)
Multiply
4340 / 8100
Simplify by dividing by 20.
217/405 (about 0.535)
This is less than 2/3 (about 0.66), so it has to be "a" because all the other options are greater than 2/3
For the trinomial x^2-11x+10 determine if the factors of c will will be both positive, both negative, or opposite signs.
Answer:
Two negatives
Step-by-step explanation:
I'm assuming by 'factors of c' you mean factors of the last term. For the entire trinomial, we know that there are two negative signs. To be able to get a negative 11x and then a positive 10, we would need two negatives, since two negatives equal a positive. Hope that helps!
If there's a three day rain forecast for the probability of rain , 70% Friday, 70% Saturday, 70% Sunday A) work out the probability that it will rain on all three days B) work out the probability that it will rain on exactly two consecutive days
Answer:
a) 34.3%
b) 49%
Step-by-step explanation:
In order to find the probability of a sequence of events, we need to multiply each individual probability by the others in decimal form. Therefore, we need to turn these probabilities into decimal form by dividing them by 100 like so..
70% / 100 = 0.70
Now we multiply all of them together and multiply the product by 100 to get the percentage.
0.70 * 0.70 * 0.70 = 0.343
0.343 * 100 = 34.3%
34.3% is the probability of it raining on all three days. Now to find the probability of it raining on two consecutive days we do the same but multiply only 2 probabilities
0.70 * 0.70 = 0.49
0.49 * 100 = 49%

Find the value of a5, given the sequence defined as: a1 = 32 an = (1/2)an-1
Answer:
a5 = 2
Step-by-step explanation:
If a1 = 32,
a1 = 1/2 a0 = 32
a0 = 64
With that, we know that
a0 = 64,
a1 = 32
so, a2 is definitely 16. From that, we may know the formula,
an = a0 (1/2)^n
a5 = a0 (1/2)^5
a5 = 64 (1/32)
a5 = 2

Step-by-step explanation:
At a real estate agency, an agent sold a house for $360,000. The commission rate is 25% for the real estate agency and the commission rate for the agent is 30% of the amount the real estate agency gets. How much did the agency make on the house? How much did the agent earn in commission?
Answer: See explanation
Step-by-step explanation:
a. The amount that the agency make on the house will be 25% of $360,000. This will be:
= 25% × $360,000
= 25/100 × $360,000
= 0.25 × $360,000
= $90,000
b. The amount that the agent earn in commission will be:
= 30% × $90,000
= 30/100 × $90,000
= 0.3 × $90,000
= $27,000

Suppose b varies directly with a and inversely with the square root of c. If b=5 when a=2 and c=4, find b when a=12 and
c=100
What if b
Answer:
b = 6 when a=12 and
c=100
Step-by-step explanation:
b = (k*a)/√c
b=5 when a=2 and c=4
5 = (k*2)/√4
5 = 2k/2
Cross product
5*2 = 2k
10 = 2k
k = 10/2
= 5
k = 5
find b when a=12 and
c=100
b = (k*a)/√c
= (5*12)/√100
= 60/10
= 6
b = 6
For A and B, use the indicated operations to find the answer

Answer:
10√2
Step-by-step explanation:
This is a 45-45-90 triangle which means that the two non-hyptonouse lenghts are the same which means that the bottom lenght of the triangle is also 10 units
We can then use a^2+b^2=c^2 to solve for the last side
so we have
10^2+10^2=x^2
200=x^2
sqrt200=x
and I see that they want an exact answer so you simplify sqrt200 to
10√2

Answer:
Area = 342[tex]cm^2[/tex], Perimeter = 22.79 cm
Step-by-step explanation:
First, divide the shape into 3:
An arc, a square, and a triangle.
Dimensions of shapes:
Arc:
Degree = 40°
Arms = 4 cm
Square:
All sides are 4 cm
Triangle:
base = 3 cm
height = 4 cm
hypotenuse = 5 cm
To get perimeter:
Arc length = [tex]\frac{40}{360} * (2*\pi * (4))[/tex] (4 is the arm length ) = 2.7925 cm
Arc arm = 4 cm
Square sides (only two are outside) = 2 * 4 = 8 cm
Triangle (only hypotenuse and base are outside) = 5 + 3 = 8 cm
So total perimeter is 2.7925 + 4 + 8 + 8 = 22.79cm
To get area:
Arc area (the pizza shape) = [tex]\frac{40}{2\pi } * \pi * (4)^{2}[/tex] (4 is the arm length) = 320 [tex]cm^{2}[/tex]
Square area = side * side = 4 * 4 = 16 [tex]cm^{2}[/tex]
Triangle = (1/2) * base* height = (1/2) * 3 * 4 = 6[tex]cm^{2}[/tex]
So total area is 320 + 16 + 6 = 342[tex]cm^2[/tex]
Answer:
Area=27.58 cm^2
Perimeter =22.29cm
Step-by-step explanation:
The shape consists of a sector and a trapezium
For area= area of sector +area of trapezium
[θ/360*πr^2]+[1/2(a+b)h]
[40/360*3.14*4^2]+[1/2(4+7)4]
5.58+22
27.58cm^2
For perimeter = perimeter of sector +perimeter of square +perimeter of triangle
[θ/360*2πr]+[4s]+[1/2(a+b)]
[40/360*2*3.14*4]+[4*4]+[1/2(4+3)]
2.79+16+3.5
22.29cm

What is the difference between a service charge and a finance charge?
A) A service charge is a fee which must paid every month, while a finance charge is a one-time fee assessed at the beginning or end of a loan period.
B) A service charge is a flat fee charged to a borrower, while a finance charge is a fee charged to a borrower based on the amount borrowed.
C) A service charge is a fee assessed by a lender, while a finance charge is a fee charged by a financial institution, such as a bank.
D) A service charge is a fee assessed by a lender other than interest, and a finance charge is the total of the interest paid on a loan and the service charge.
Please EXPLAIN work in detail, Thank You!
Answer:d
Step-by-step explanation: because that’s the answer
D) A service charge is a fee assessed by a lender other than interest, and a finance charge is the total of the interest paid on a loan and the service charge.
According to accounting and finance terminology, the finance charge is the total fees that you pay to borrow the money in question. This means that the finance charge includes the interest and other fees that you pay in addition to paying back the loan.
You have $20. This week, you choose to put 10% in your piggy bank. Next week, you decide to put 10% of your money in your bank again. How much money do you have left to spend?
Answer:
the amount left is 16.2
Step-by-step explanation:
The computation of the amount of money spend is shown below;
Given that
Total money available $20
This week 10% would be put in piggy bank
and, in next week 10% of the money would be put again in piggy bank
So the money left is
= $20 - $20 × 10% - ($18 × 10%)
= $20 - $2 - $1.8
= $16.2
Hence, the amount left is 16.2
