Answer:
72.3
Step-by-step explanation:
So, to find the average you need to add all the numbers together and divide it by the amount of numbers there are, if that makes sense.
so in your question: 100 + 90 + 80 + 89 + 75 + 0= 434
and there are 6 numbers that you had to add together, so you divide 434 by 6, which is 72.3 so that's the answer! It's quite easy once you understand how to do it :)

One store has carrots on sale for $1.1 for 3 pounds, while another store has carrots on sale for $0.78 for two pounds. Which store has the better deal?
Maria want to buy a pencil for everyone in her class. It costs $0.78 for 3 pencils. How much Maria have to spend if she bought a pencil for each of her 24 classmate?
Answer:
1) The store selling for 1.1 per 3 lbs
2) $6.24
Step-by-step explanation:
1)
1.1/3 = 0.37
0.78/2 = 0.39
0.37 is cheaper so it's a better deal
2)
[tex]\frac{0.78}{3} =\frac{x}{24} \\\\3x=18.72\\x=6.24[/tex]
Answer:
1.10 for 3 is the better deal. It will cost $6.24 for the pencils.
Step-by-step explanation:
Do two separate problems but find how much it is for 1 carrot. So the first is:$1.10 divided by 3 carrots = .366 or 37 cents per carrot.
The second one is: .78 divided by 2 carrots = .39 cents per carrot.
If you break 24 students into groups of 3, that would be 8 groups. 24 divided by 3 = 8.
8 sets of 3 pencils is .78 x 8 = $6.24

d) final coat of notebook: $3.15
I need help plz any one if you can explain
Answer:
C
Step-by-step explanation:
A 1 2-liter bottle for $0.89
1 liter = .89 /2 = $0.445
B 3 1-liter bottles for $1.50
1 liter = $1.50/3 = $0.50
C 24 0.5-liter bottles for $5.25
1 liter = 5.25 / 12 = $0.4375
D 36 0.25-liter bottles for $4.75
1 liter = $4.75 / 9 = $0.53
Give me brainllest
Answer:
C is the best buy
Step-by-step explanation:
0.89/2 = 0.445
3 * 1 litre bottles = 3 litres
1.50/3 = 0.5
24 * 0.5 litres = 12 litres
5.25/12 = 0.4375
36 * 0.25 liters = 9 liters
4.75/9 = 0.52777777

Trechelle is buying a sports coat that has a regular price of $90. This coat is on sale with a 20% discount. She knows she needs to pay 8\%8% sales tax on the discounted price. Trechelle thinks to herself 20\%-8\%=12\%20%−8%=12%. She now believes this means she is really only getting a 12% discount, and 12% of $90 is $10.80. She works out the sports coat will cost her $79.20$. Is Trechelle’s reasoning correct or will the sports coat actually cost a different amount?
Answer:
Trechelle's reasoning is incorrect.
Step-by-step explanation:
the cost is $88.2. hope it helps bye.

A circle is shown. 4 radii are drawn. Chords are drawn to connect the radii points on the circle to form 2 triangles. The triangles have base lengths of 6 centimeters and the other 2 sides have lengths of 5 centimeters. The distance between the base of the triangle to the outline of the circle is 1 centimeter. Everything around the triangles is shaded.

Will mark branliest. What can the maximum number of digits be in the repeating block of digits in the decimal expansion of 1/17?
Answer:
Step-by-step explanation:
Let n=2α⋅5β⋅m , where gcd(m,10)=1 . Then, the decimal expansion of 1n is of the form
0.a1…akak+1…ak+ℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(1) ,
where k=max{α,β} and ℓ is the least positive integer for which m∣(10ℓ−1) . In other words, ℓ is the order of 10 in the multiplicative group of units modulo m . So ℓ∣ϕ(m) by Lagrange's theorem.
In particular, if gcd(n,10)=1 , then α=β=k=0 , m=n , and
1n=0.a1…aℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(2)
Therefore, we know that
117=0.a1…aℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(3)
Here ℓ is the least positive integer for which 17 divides 9…9ℓtimes , and we know that ℓ divides ϕ(17)=16 .
Successively squaring 10 modulo 17 gives
102≡−2(mod17),104≡4(mod17),108≡−1(mod17),1016≡1(mod17) .
So ℓ=16 in expansion (3) .
In fact,
a1…a16×17=1016–1.
a1…a8+a9…a16=108−1 .
The first fact has nothing to do with the denominator n being prime. The second fact has everything to do with n being prime, and was discovered by E. Midy in 1836 .

Answer:
55 bricks
Step-by-step explanation:
First find the area of one brick by multiplying 10x6x4, which is 240 cm^3. Then divide that from 13,200 which gives you 55 bricks.
Answer:
55 bricks
Step-by-step explanation:
First, we know they used 13,200 cm^3 of concrete. cm^3 is a volume, so in order to find how many bricks can be made, we must find the volume of each brick. Multiply the dimensions of each brick. 10*6*4=240cm^3. Now, divide 13,200cm^3/240cm^3=55 bricks
Kelly deposited $4,205 in an account for 3.5 years. She earned $662.29 in interest. What interest rate did the bank pay her?
Answer:
r = 4.5%
Step-by-step explanation:
Formula:
I = Prt
r = I/(Pt)
Given:
I = 662.29
P = 4205
t = 3.5
Work:
r = I/(Pt)
r = 662.29/(4205 * 3.5)
r = 662.29/14717.5
r = 0.045
r = 4.5%
find the circumference of a circle with a radius of 9.8 in. (urgent)
Answer: 61.58
Step-by-step explanation:
C = 2 π r = 2 · π · 9.8
π = pi
radius times pi (3.14) times 2 (because two radius makes the diameter)
9.8 times 3.14 times 2 = 61.57522in

Regina buys eggs at the local supermarket. They are sold in different quantities and at different prices. The quantities and prices are shown.
Brand A: 6 eggs $1.77
Brand B: 12 eggs $3.75
Brand : 18 eggs $5.24
Brand D: 24 eggs $7.10
Assuming all the eggs are of similar quality, which decision should Regina make if she wants to get the best price per egg?
Help
Answer:
Brand C
Step-by-step explanation:
Brand A: 1.77/6=$0.30
Brand B: 3.75/12=$0.31
Brand C: 5.24/18=$0.29
Brand D: 7.10/24=$0.30
Based on the price per egg of each brand (calculated above), the best price per egg would be brand C.
Beth has already jogged 3 miles. She plans to jog less than 12 miles. Which inequality can be
used to find the number of miles (m) she has left to jog?
m - 3 < 12
m +3 > 12
m-3 > 12
m+ 3 < 12
Answer:
The total number of miles Beth plans to jog cant go over 12, and she has already jogged for 3 miles, then she needs to jog for another m miles. This can be written mathematically like: 3 + m < 12.

Answer:
Zoom it
mark me as brainliest
The answer is 3
Open the brackets:2(3x - 7)=6x -14
6x - 14 +18 =22
Take all the numbers to the other side
6x =22+14-18
6x =18
Divide by 6 kn both sides
x=3
Which expression represents the relationship between the step number n and the total number of small squares in the pattern?

A.
B.
C.
D.
Answer: n squared - 1
Step-by-step explanation:
The relationship between the step number {n} and the total number of small squares in the pattern is -
f(n) = 2ⁿ - 1.
What is expression in mathematics?An expression in mathematics is a combination of terms both constants and variables.
Given is a pattern of small squares as described -
Step 1 has 0 squares.
Step 2 has 3 squares : 2 by 2 but missing the lower right square.
Step 3 has 8 squares : 3 by 3 but missing the lower right square.
We can write the general expression for step {n} as -
Step {n} will have : 2ⁿ - 1 squares with missing the lower right square.
or
f(n) = 2ⁿ - 1
Therefore, the relationship between the step number {n} and the total number of small squares in the pattern is -
f(n) = 2ⁿ - 1.
