Benjamin bought a 3-pound bag of flour for $6.95. What is the unit price per ounce of flour? (1 pound = 16 ounces)

Answers

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

since money is measured in hundreths, you would round up (because thats how money works) so it would be roughly 15 cents. unless your teacher wants you to round down to 14 cents

Jamian bought a total of 35 bagels and donuts for a morning meeting. He paid a total of

$25.75. Each donut cost $0.55 and each bagel cost $1.20. The system of equations

b + d = 35

1.200 + 0.55d = 25.75 models this situation, where b is the number of bagels and d

is the number of donuts. How many of each did Jamian buy?

{ 1.200

Jamian bought

bagels and

donuts.

Answers

Answer:

Number of bagels = 10

Number of donuts = 25

Step-by-step explanation:

Let Number of bagels = b

Number of donuts = d

As given,

Each donut cost $0.55 and each bagel cost $1.20

⇒ Cost of d donuts = $0.55d

Cost of b bagels = $1.20b

Also given,

Jamian bought a total of 35 bagels and donuts

⇒ b + d = 35 ........(1)

Also,

He paid a total of $25.75.

⇒ 1.20b + 0.55d = 25.75 .........(2)

Now,

Multiply equation (1) by 1.20 , we get

1.20( b + d = 35 )

⇒1.20b + 1.20d = 42 ..........(3)

Now,

Subtract equation (2) from equation (3), we get

1.20b + 1.20d - ( 1.20b + 0.55d ) = 42 - 25.75

⇒1.20b + 1.20d - 1.20b - 0.55d = 16.25

⇒0.65d = 16.25

⇒d = [tex]\frac{16.25}{0.65}[/tex] = 25

⇒d = 25

Put the value of d in equation (1) , we get

b + d = 35

⇒b + 25 = 35

⇒b = 35 - 25 = 10

⇒b = 10

∴ we get

Number of bagels = b = 10

Number of donuts = d = 25

write the equation 6x-3y=9 in slope-intercept form. Then graph the line described by the equation .

A student said we cannot subtract 1.97 from 20 because 1.97 has two decimal digits and 20 has none. Do you agree with his statement? Explain or show your reasoning.

Answers

Answer:

Step-by-step explanation:

everything has a infinite amount of zeroes behind the decimal point or where it ends at least

Just add a decimal after 20 because it is a whole number.
20.00 - 1.97 = 18.03
Just remember to line up your decimals when subtracting.

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?

Answers

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

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

Answers

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]

What is the function rule for this table? 10 POINTS! BRAINLIEST to correct answer!

Answers

The function tule for the table is
y = 2x

If you line the table vertically, you can see the x value is +1 because how does 0 go to 1, you add one to it.

With the y variable, you can view its being multiplied by 2 since 5x2 = 10 , 10x2 = 20 and so on.

Therefore the function rule is y=2x

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.

Answers

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 fewest number of consecutive primes, starting with 2, that when summed produce a number divisible by 7?

Answers

Answer:

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.
