Answers

Answer 1
Answer:

Answer:

2500g

Step-by-step explanation:

In the Metric Decimal System. Each subunit (to the left) is 10 times higher or 1/10 times lower .

1Kg           1hg         1dag    1g        1dcg       1cg        1 mg

1000g     100g      10g     1g         0.1g            0.01g       0.001g

From the scheme above, we have many relations. The one that answers the question is below followed by a rule of three:

1 kg----1000g

2.5kg-----x

x=2500g
Answer 2
Answer: 1 kg= 1000g

So to go from kilograms to grams, multiply by 1000:
2.5kg*1000= 2500 g

Answer: 2500 g

A hose fills a hot tub at a rate of 2.58 gallons per minute. How many hours will it take to fill a 268​-gallon hot​ tub?

Answers

Answer:

1.73 hours

Step-by-step explanation:

This can be solved with proportions.

(2.58 gallons)/(1 minute) = (268 gallons)/(x minutes) \n

Cross multiply and you get:

2.58x gallons * minutes = 268 gallons * minutes\n

Divide by 2.58 gallons and you get:

x minutes = (268 gallons)/(2.58 gallons) * minutes \nx minutes = 103.876 minutes\nx = 103.876 minutes\n

And to find out the number of hours that is, divide by 60 and you get 1.73 hours.

Which statement best describes the area of the triangle shown below? A coordinate grid is shown with a triangle.. The base is 4 units, and the height is 4 units. A It is one-half the area of a rectangle of length 4 units and width 2 units.B.It is one-half the area of a square of side length 4 units.
C.It is twice the area of a rectangle of length 4 units and width 2 units.
D.It is twice the area of a square of side length 4 units.

Answers

Answer:

The answer is B.It is one-half the area of a square of side length 4 units.

Step-by-step explanation:

Given a coordinate grid shown with triangle of measurements with base 4 units and height also 4 units.

We have to find the area of triangle which can be calculated as

⇒ Area=(1)/(2) * base * height

                  = (1)/(2)* 4 * 4=8squareunits

we have to choose the statement describes the area of the triangle evaluate above.

Option A: Not matched ∵equals to (1)/(2)[area of rectangle of length 4 units width 2 units]= (1)/(2)* 4 * 2=4 sq units                                  

Option B: matched : given one-half the area of a square of side length 4 units.

⇒ (1)/(2)* 4 * 4=8 squnits

Option C : Not matched : It is twice the area of a rectangle of length 4 units and width 2 units

⇒2* length* breadth=2* 4* 2=16 sq units

Option 4 : Not matched : It is twice the area of a square of side length 4 units.

⇒ 2* 4 * 4=32 squnits

So, the correct option is B. It is one-half the area of a square of side length 4 units.

Answer:The answer is B.
