Answer:
-127.488°
Step-by-step explanation:
45" is 0.75 of 1', so -128° 30' 45" = -128° 30.75'
Next: 30.75' is 30.75/60 of 1°, and or -128° plus 0.5125 of 1°.
The final answer is found by adding 0.5125° to -128°:
-128.0000°
+ 0.5125°
--------------------
-127.4875
To the nearest thousandths of a degree, that would be -127.488°
Answer:
There are 9 000 000 = 9 million reptiles in the US.
Step-by-step explanation:
Percentages and ratio:
The double of a measure, for example, is 200% of the measure.
So 1000% of a measure is 10 times the measure.
There are 90 million pet dogs in the US. The number of dogs is 1000% the number of reptiles.
The number of pet dogs is 10 times the number of reptiles, which means that:
There are 9 000 000 = 9 million reptiles in the US.
10,740
Step-by-step explanation:
multiply by 3, because 4 x 3 equals 12, so that infers 3580 x 3, which equals 10,740
Answer:
5
The least number 12500 need to be multiplied by to make it a perfect square is 5.
Corrected question;
By which least number should 12500 be multiplied to make them perfect squares
Step-by-step explanation:
Perfect squares are squares of whole numbers.
Like 4,9,16 etc.
For 12500, we need to first of all reduce it to its Lowest factors.
12500 = 2×2×5×5×5×5×5
Grouping the factors into pairs of thesame factors.
12500 = (2×2) × (5×5) × (5×5) × 5
Looking at the pairs of factors, we can observe that the last factor 5 need to be paired to make the number a perfect square.
So, when the number is multiplied by 5;
12500 × 5 = (2×2) × (5×5) × (5×5) × (5×5)
62500 = (2×2) × (5×5) × (5×5) × (5×5)
62500 = (2×5×5×5)^2 = 250^2
Hence, 62500 is a perfect square.
The least number 12500 need to be multiplied by to make it a perfect square is 5.
Obtuse, because the triangle has an angle greater than 90 degrees.
