The Kennedy Middle School cafeteria charges students $3 for 1 6 of a pizza. What is the cost per pizza?

Answer:

[tex]\huge\boxed{a=-21}[/tex]

Step-by-step explanation:

[tex]-7=\dfrac{1}{3}a\to\dfrac{1}{3}a=-7\qquad|\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup\cdot\dfrac{1}{3\!\!\!\!\diagup}a=(-7)(3)\\\\a=-21[/tex]

9514 1404 393

Answer:

  false

Step-by-step explanation:

You can check to see if the sum of squares of the smaller two numbers is equal to the square of the larger.

  8² +15² vs 17.5²

  64 +225 vs 306.25

At this point, you need go no further. The sum of two integers will not have a fractional part, so cannot be equal to 306.25.

  289 vs 306.25 . . . . the long side is too long for a right triangle.

If you were familiar with some of the Pythagorean triples, you would know that the closest triple is {8, 15, 17}, so (8, 15, 17.5) does not represent a right triangle.

A few common Pythagorean triples are ...

  {3, 4, 5}, {5, 12, 13}, {7, 24, 25}, {8, 15, 17}, {9, 40, 41}

Answer:

105km

Step-by-step explanation:

From the above question, the scale is

2.5 cm = 15km

Therefore,

17.5 cm = x

We Cross Multiply

2.5cm × x = 15km × 17.5 cm

x = 15km × 17.5cm/2.5

x = 262.5/2.5

x = 105 km

Therefore, the number of actual kilometres that are represented by 17.5 centimetres on the map is 105 kilometres.

Answer:

x=1.5

Step-by-step explanation:

Answer: x = 18/12 or 3/2

Step-by-step explanation:

5x + 2 = 17x - 16

2 = 12x - 16

18 = 12x

18/12 = x

Answer:

52metre

Step-by-step explanation:

Let us use proportion in solving this question, the land has a scale of 1 1/4 cm to 3 1/4 m then the proportion is

( 1 1/4)/ (3 1/4 ) =[blueprint of the plot of land/length of the actual peace of land]

But we need to convert those mixed fractions to improper fraction for easy simplification

1 1/4= [(4×1)+4]= 5/2

3 1/4=[(4×3)+1)]=13/4

Then we can proceed with simplification as

(5/2)/(13/4)=[blueprint of the plot of land/length of the actual peace of land]

But we were given length of the actual peace of land as 20 cm, then

(5/2)/(13/4)=[blueprint of the plot of land/20]

If we cross multiply we have

[blueprint of the plot of land] ×13/4 =5/2 ×20

[blueprint of the plot of land] =(5/2 ×20)÷(13/4)

= 50/(13/4)

=(4×13)/50

= 52

Therefore, the length of the actual peace of land is 52metre

Answer:

11 months

Step-by-step explanation:

Nate needs $850 total, and he already has $300. So, the money left that he needs is 850-300 which is $550.

Now, he can save $50 each month, and we need to find the amount of months, x, it will take to reach his goal.

He needs $550, to the equation is:

50x=550

We need to isolate x, so we divide both sides by 50.

x=11

It will take Nate 11 months to save for the trip.

Answer:

11 months

Step-by-step explanation:

850-300=550

550÷50=11

Answer:

$1000 + $25m and $1300 - 25m ;

1100 + 2.75m

2010 (4th month)

2011 ( 7th month)

Step-by-step explanation:

Joline's account :

Initial deposit = $1000

Monthly deposit = $25

Monthly withdrawal = $25

Number of months = 12

Let m = number of month at any point in time

Initial deposit + total deposit

Amount in Joline's account ; first 12 months

$1000 + $25m - - - (1)

Next 12 months :

$1000 + $25 *12 - 25m

1300 - 25m

Sofia's account :

Deposit amount = $1100

Interest per month = 0.25% = 0.0025

1100 + (1100 * 0.0025 * m)

1100 + 2.75m - - (2)

To find the month:

Equate equation 1 and 2, then find m

$1000 + $25m = 1100 + (1100*0.0025*m)

1000 + 25m = 1100 + 2.75m

25m - 2.75m = 1100 - 1000

22.25m = 100

m = 100 / 22.25

m = 4.494

In year 2010, they have approximately the same amount in the fourth month

1300 - 25m = 1100 + 2.75m

1300 - 1100 = 2.75m + 25m

200 = 27.75m

m = 200 / 27.75

m = 7.207

In 2011 ; they have approximately the se amount in the 7th month

Answer:

0.00675

Step-by-step explanation:

0.00675 rounded miles

Answer:

All are acute

Step-by-step explanation:

Acute angles are any angles that are less than 90°.

Right angles are angles that measure 90°.

Obtuse angles are angles that are more than 90°.

As we can see, 24, 29, and 32 are all less than 90°, making them all acute.

Best of Luck!

Answer:60

Step-by-step explanation:

32 divided by 4 is 8 8 an hour per worker 90 mins is hour and a half 8 times 5 40 each person can make 4 in 30 min so 20

40+20=60

sorry i am a bad explainer

60 widgets can five workers make in 90 minutes.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

4 workers can make 32 widgets in an hour .

1 hour = 60 mint.

now,

4 workers work 60 mint. to make 32 widgets

so, 1 workers work 60 mint. to make =32/4

                                                             =8 widgets

1 workers work 1 mint. to make =8/60 widgets

i.e.  1 workers work 90 mint. to make =8*90/60 widgets

5 workers work 90 mint. to make =8*90*5/60 widgets

solving we get,

5 workers work 90 mint. to make =60 widgets

hence, 60 widgets can five workers make in 90 minutes.
