How could you explain that 21/30 is greater than 2/3?

Answers

Answer 1

Answer: well its greater than 2/3, because 2/3= 20/30, so 21/30 is greater.

Answer 2

Answer: To begin with, 2/3 can also be written as 20/30
Now we see that 21 is greater than 20.
So, in this one way we can say that 21/30 is slightly greater than 2/3.
Still didnt understand?
Lets go deep down, Maybe converting the fraction to a decimal will be good.
So when we convert the fraction 21/30, it gives us the decimal value:0.7
The same thing with 2/3, it gives us a non-ending decimal value:0.6667
However, dont get confused by the fact that 0.66667 is so close to 0.7
Although it is close enough, 0.7 is still higher.
In closure, 21/30 is greater than 2/3

since 10 is smaller than 100, Garricks plant is SHORTER than Zan's plant

This means that each mm for Garrick will result in a GREATER percent error

10-8=2. His measurement was 2 mm off

100-88=12 so Zans answer was 12 mm off

2/10*100=20%

12/100*100=12%

The required, any triangle that has two sides and the included angle between them given can have its area calculated using the trigonometricarea formula.

What is the triangle?

The triangle is a geometricshape that includes 3 sides and the sum of the interior angle should not be greater than 180°

The trigonometric area formula can be used to calculate the area of a triangle when we know the lengths of two sides and the included angle between them. The formula is:

Area = 1/2 * a * b * sin(C)

where a and b are the lengths of the two sides, and C is the angle between them.

Therefore, if we are given the lengths of two sides and the angle between them, we can use the trigonometric area formula to calculate the area of the triangle. This formula is particularly useful when we do not know the height of the triangle or cannot easily calculate it using other methods.

So, any triangle that has two sides and the included angle between them given can have its area calculated using the trigonometric area formula.

If you draw a line diagonal from one top corner to the opposite bottom corner you will have made 2 triangles. Then you can use the Pythagorean theorem to figure out the diagonal measure (or hypotenuse of the triangle.c squared=15 squared + 27 squaredc squared= 225+729c squared= 954c= square root of 954c=30.88I would round that up to 31 inches

B.31 inches, I got this from 30.88 and I rounded.
1st. Draw a line diagonal from one top corner to the opposite bottom corner(you will have 2 triangles)
2nd.Pythagorean theorem to figure out the hypotenuse of the triangle.
c^2=15^2 + 27^2 c^2= 225+729 c^2= 954 c= square root of 954 c=30.88, aka 31 inches.

Madison loves her stuffed dolphin toy. The toy is 27 inches long. If her brother came and sliced the dolphin in half what would the size of the dolphin be?

Answers

27 divided by two(half) =13.5 inches :)

The size of the dolphin would be 13.5 inches long because half of 27 is 13.5.

27/2 = 13.5

Alida has a cough her mother gives her 10ml of cough syrup and 0.5L of water how many ml of liquid was she given in all

Answers

Answer:

510ml

Step-by-step explanation:

Answer:

510

Step-by-step explanation:

1ml=0.001L

so lets take "x" as the amount of ml that 0.5 liters equal:

x ml=0.5L

cross multiply:

$(1)/(0.001) =(x)/(0.5)$

0.5=0.001x

x=500

so 500ml=0.5l

add 10ml of cough syrup to 500 ml of water to get TOTAL liquid quantity:

500+10=510

510 ml
