Answer:

3.25 round to the nearest whole number is 3

Step-by-step explanation:

The solution of the 3.25 when rounded off to the nearest whole number according to the rule of rounding numbers is 3.

Rounding off numbers means adjusting a number simpler by adjusting it to its nearest place according to certain rules.

In rounding off numbers, the place value starts from tens place.

Rounding to the nearest whole number: Look at the digit immediately to the right of the decimal point. If it is 5 or greater, round the number up. If it is less than 5, round the number down.

As per the given question,

Rounding 3.25 to the nearest whole number we look at the digit immediately to the right of the decimal point though it is less than 5 so, the number gives 3, according to the rule of Rounding numbers.

The solution of the 3.25 when rounded off to the nearest whole number is 3.

Answer:

a., d

Step-by-step explanation:

An open circle on a number does not include the number that has the circle. A closed circle includes the number that has the circle.

An arrow pointing to the right includes numbers that are greater than the number that has the circle. An arrow pointing to the left includes numbers that are less than the number that has the circle.

The equation is x > 5.

That means that 5 is not included, and all numbers greater than 5 are included.

5 not included: Use an open circle.

Numbers greater than 5: arrow point to the right.

Answer; a., d

Answer:

298 rolls

Step-by-step explanation:

As per the above, we were given that Emma bought 17 packages of rolls.

We need to find the number of rolls in the packages that he bought, hence

Total rolls = 17 packages × 18 rolls per package

= 306 rolls

Furthermore, since we have 8 rolls leftover, then total number of rolls eaten would be;

Rolls eaten = Total number of rolls in the beginning - rolls leftover

= 306 - 8

= 298 rolls

It therefore means that 298 rolls were eaten by Emma.

• Sum of three numbers in an AP is -3

• Their product is 24.

• The numbers .

Let the numbers be .

• (a-d) , a , (a+d) .

A/Q ,

• Sum of numbers = -3

=> a-d + a + a+d = -3

=> 3a= -3

=> a = -1 .

Now ,

• Product of numbers = 24

=>( a-d)(a)(a+d)= 24

=> (a²- d²) (a) = 24

=> (1- d²)(-1)=24

=> -1+d²= 24

=> d²= 25

=> d = ±5.

If d = 5 the numbers are :

• a+d , a , a-d = 4 , -1 , -6

If d = -5 the numbers are :

• a+d , a , a -d = -6, -1 , 4 .

The numbers are :

4 , -1 , -6 and -6, -1,4

Answer:

The two number are 10 and 12

Step-by-step explanation:

Two whole numbers have a least common multiple of 60.

We are told that:

-Each number is less than or equal to 12.

The first thing we know is that: one of that two number is 12

The next step would be to find the factors of 60

The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

The factors of 60 that is equal to or less than 12 is

1, 2, 3, 4, 5, 6, 10, 12

We would find which of these number that has the greatest common factor of 2 with 12

The factors of 10 are: 1, 2, 5, 10

The factors of 12 are: 1, 2, 3, 4, 6, 12

Then the greatest common factor is 2...

Also calculating the least common factor of 10 and 12

Multiples of 10:

10, 20, 30, 40, 50, 60, 70, 80

Multiples of 12:

12, 24, 36, 48, 60, 72, 84

Therefore,

LCM(10, 12) = 60

Therefore, two numbers with the least common multiple of 2 and greatest common factor of 60 is 10 and 12

Answer:

x = -113

y = 30

Step-by-step explanation:

110+10+2y=180

2y=180-110-10

=60

y=60/2

y=60/2 =30

-3x-10-2x+15+110+120+95=540

-3x-2x =540+10-15-110-120-95

-5x=210

x=210/-5

x=210/-5 = - 42

Step-by-step explanation:

Here,

110+2y+10=180°(being sum of angles in

a straight line)

y=180-120

y=60°,,

now,

to find the value of X,

120+95+110+3x-10+2x+15=540°(being sum of all angle of pentagon)

330+5x=540°

5x=540-330

5x=210

X=210/5

x=42°,,

Answer:

3,240°

Step-by-step explanation:

Sum of interior angles of n-sided polygon is given as (n - 2)180. Where n = number of sides of the polygon.

Sum of angles of a convex 20-gon = (20 - 2)180

= (18)180 = 3,240°

Sum of interior angles of a convex 20-gon = 3,240°

Answer:

3,240

Step-by-step explanation:

(n-2)180 n is the number of sides

Substitute 20 for n, then simplify

(20 - 2)180 = (18)180 = 3,240

3 candy bars for 0.30

Step-by-step explanation:

The same amount of bars for less is the better buy

Answer:

3 candy bars for $0.30 each is the better buy

Step-by-step explanation:

We must do the math to find out how much 3 candy bars will cost for 30 cents each.

0.30 x 3 = 0.90

Therefore, three candy bars cost 90 cents. 90 cents is less than a dollar and 50 cents. Therefore, the 3 candy bars for $0.30 each is the better deal.

Answer:

44 minutes

Step-by-step explanation:

With regards to the above information, we can calculate the minutes in which Martina's call lasted as shown below;

We can make y represent the minutes

15 - 8y/100 = 11.48

15 - 0.08y = 11.48

15 - 11.48 = 0.08y

0.08y = 3.52

y = 3.52/0.08

y = 44

It therefore means that Martina's call lasted for 44 minutes.
