Math and Arithmetic

2.90 hours is equivalent to 2 hours and 54 minutes. To convert the decimal portion, you multiply 0.90 by 60, which gives you 54 minutes. Therefore, 2.90 hours can be expressed as 2 hours and 54 minutes.

The sum of 1387 and 5678 is 7065.

Interval training typically involves alternating periods of high-intensity exercise with lower-intensity recovery or rest phases. This approach can be applied to various forms of exercise, such as running, cycling, or strength training. The high-intensity intervals push the body to exert maximum effort, while the recovery periods allow for partial rest, enhancing overall endurance and fitness levels. This method is effective for improving cardiovascular health, boosting metabolism, and increasing athletic performance.

Oh, dude, it's like this: "how much further" typically means to add distance or time to a current measurement or situation. If you're driving and someone asks, "How much further?" they want to know the additional distance you have left to travel. So, yeah, it's basically about adding on, whether it's miles on the road or minutes in a meeting.

'4'

4^(3) = 4x4x4 = 16 x 4 = 64

This question cannot be answered sensibly. A square foot is a measure of area, with dimensions [L2]. A foot is a measure of distance, with dimensions [L]. Basic dimensional analysis teaches that in most cases you cannot convert between measures with different dimensions without additional information.

The Area could be a rectangle/ square, or other four sided figure.

However, assuming it is a square.

Then one side is sqrt(1521) = 39/ ft

Hence being a square to ther side is also '39' ft.

NB You need to be more specific as to the shape of the area.

[4] / [-1/2] =>

4/1 X -2/1 = -8/1 = -8 The answer!!!!!

Note the change of sign to (X) and the inversion of the denominator.

A "step" is not a very precise measurement; different people have steps of different lengths. However, a step is usually slightly less than a meter, so the answer will probably be: somewhat more than 1200 steps.

One very easy way to answer this is to see that 30 = 2 * 15. 2 = 200%. You can check this by seeing that 100% of 15 is 15, so twice that (200%) is 30.

The word "Hello" can be represented in binary using ASCII encoding. Each letter corresponds to a specific ASCII value that can be converted to binary. For example, "H" is 72 (binary 01001000), "e" is 101 (binary 01100101), "l" is 108 (binary 01101100), and "o" is 111 (binary 01101111). Therefore, "Hello" in binary is: 01001000 01100101 01101100 01101100 01101111.

There are 0.009km in 9 metres, however if the question is how many km are there in 9 miles then the answer is 14.5km (to 1 decimal place)

Remember

12 inches = 1 foot.

So in 247 inches there are 247/12 = 20 feet and 7 inches.

Acute ; < 90 degrees

Right Angles ; 90 degrees

Obtuse ; >90 degrees but < 180 degrees.

Straight line ; 180 degrees . An arc swept around a point on a straight line

Reflex ; The 'outside' angle to an acute or obtuse angle.

It is: 3*3*3 = 27

x - 4y = 4

Algebraically rearrange to

4y = x - 4

y = x/4 - 4/4

y = (1/4)x - 1

It is now in the form of y = mx + c

Where 'm' is the slope and 'c' is the y-intersect.

Hence the slope is ' 1/4' and y intersect is ' -1 '.

LCM of 20 and 49 is 980.

14 out of 6 simplifies to 7/3 by dividing both numbers by 2. As a mixed number, 7/3 = 2⅓.

To find the middle quantity, we first calculate the total sum of the five quantities using the average. The average of 5 quantities is 70, so their total sum is (5 \times 70 = 350). The known quantities are 50, 70, 60, and 80, which sum to (50 + 70 + 60 + 80 = 260). Therefore, the middle quantity is (350 - 260 = 90).

As a mixed number, 56 is the same as 1 55/1. When we convert it back into an improper fraction we get 1 x 1 = 1 + 55 = 56. Then we place it over the original denominator so 56/1.
