Benjamin bought a 3-pound bag of flour for $6.95. What is the unit price per ounce of flour? (1 pound = 16 ounces)
Answer:
Step-by-step explanation:
Since there are 16 oz in 1 lb, to find the amount in 3 lbs, you would just multiply it by 3
16 · 3 = 48
to find the price you divide the total price by number of oz.
6.95 ÷ 48 ≈ 0.1448

An equilateral triangle has an altitude of 21 inches. What is the side
length of the triangle?
14 2
7 2
7 3
14 3
Answer:
7[tex]\sqrt{3}[/tex]
Step-by-step explanation:
the altitude creates two congruent 30-60-90° triangles
the ratio of the sides in a 30-60-90°, respectively, are 1 : [tex]\sqrt{3}[/tex] : 2
therefore we can set up a proportion to find the side length:
let 'x' = side length of equilateral Δ
[tex]\sqrt{3}[/tex] / 1 = 21 / x
cross-multiply:
[tex]\sqrt{3}[/tex]x = 21
x = 21 / [tex]\sqrt{3}[/tex]
rationalize the denominator by multiplying numerator and denominator by [tex]\sqrt{3}[/tex]
21[tex]\sqrt{3}[/tex] / [tex]\sqrt{3}[/tex]·[tex]\sqrt{3}[/tex] = 21[tex]\sqrt{3}[/tex] / 3 or 7[tex]\sqrt{3}[/tex]

The floor of a room with dimensions 16 by 12 is covered with square tiles, each of length 0.32. How many of such tiles will be needed to cover one third of the room?
Answer:
625 tiles
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Total room floor area = 16 × 12 = 192
So, area of one third room = 192 × (1 ÷ 3)
Area of one third room = 64
Length of each tiles = 0.32
As it is a square tile, width = length, = 0.32
o, total area of each tile = 0.32 × 0.32 = 0.1024
So, number of tiles to cover 64 area of room = 64 ÷ 0.1024 = 625 tiles.
Hence, 625 tiles needed to cover one third of room.
A total of 818 tickets were sold for the school play. They were either adult tickets or student tickets. There were 68 more student tickets sold than adult tickets.
How many aduit tickets were sold?
Answer:
375
Step-by-step explanation:
If we say there were a adult tickets sold, we know that there were a + 68 student tickets sold.
a + a + 68 = 2a + 68
818 tickets were sold in total so
2a + 68 = 818
2a = 750
a = 750/2 = 375 adult tickets sold
Answer:
443
Step-by-step explanation:
So, what we basically know is the total number of tickets for adults and students altogether. In order to start this problem itself, it will require a subtraction.
So,
That's gonna be,
818 - 68= 750
For me, personally, I have a method that works for every question similar to this one. The concept is kinda weird ,yeah but it applies to all types of questions like this one.
It is
More than= Sub-add or Subadd
So, it's gonna be
this,
818 - 68= 750
750÷ 2 = 375
Number of tickets for adults will be= 375 + 68= 443

What is the fewest number of consecutive primes, starting with 2, that when summed produce a number divisible by 7?
Answer:
5
Step-by-step explanation:
The consecutive primes starting from 2 are
2, 3, 5, 7, 11
Summing gives 2 + 3 + 5 + 7 + 11 = 28
and 28 is divisible by 7
Thus the required number of primes is 5
The fewest number of consecutive primes, starting with 2, that when summed produces a number divisible by 7 is 5.
To determine what is the fewest number of consecutive primes, starting with 2, that when summed produces a number divisible by 7, the following calculation must be performed:
2 + 3 = 5 2 + 3 + 5 = 10 2 + 3 + 5 + 7 = 17 2 + 3 + 5 + 7 + 11 = 28 28/7 = 4
Therefore, the fewest number of consecutive primes, starting with 2, that when summed produces a number divisible by 7 is 5.

given a triangle with a perimeter of 56in. we know the first side is 3 inches less than twice the length of the second side, and the third side is 10 inches more than half the length of the second side. if the second side length is h, how long is the longest side? write an equation to solve for the variable.
Answer:
Side A = 25 in
Side B = 14 in
Side C = 17 in
Step-by-step explanation:
Perimeter of a triangle = 56 in
Side B = x
Side A = 2x - 3
Side C = 1/2x + 10
Perimeter of a triangle = side A + Side B + side C
56 = (2x -3) + x + (1/2x + 10)
56 = 2x - 3 + x + 1/2x + 10
56 + 3 - 10 = 2x + x + 1/2x
49 = 3 1/2x
Note: 3 1/2x = 3.5x
49 = 3.5x
x = 49/3.5
x = 14 in
Side B = x = 14 in
Side A = 2x - 3
= 2(14) - 3
= 28 - 3
= 25 in
Side C = 1/2x + 10
= 1/2(14) + 10
= 7 + 10
= 17 in

What is the solution to the equation below? 2(x - 3) = 2x + 5
Answer: No solution
Step-by-step explanation: there is not a single value of x that would make the equation true
Answer:
Your expression for 2(x - 3) would be 2x - 6 I'm not sure what the 2x + 5 is there for. Correct me if I'm wrong. If your trying to find the value of x you cannot find it. There is no solution to find the value of X.
