Answer:
90°
Step-by-step explanation:
5, 12 and 13 are the sides of a right triangle ( Pythagorean triple )
13 is the measure of the hypotenuse whose opposite angle is 90°
12*4= 48
48 + 1 = 49
So there are 49 / 8 in the highway overall.
49 / 7 = 7
So there are 7 speed limit signs overall.
The answer is 3.0×10¹².
(5×10⁷)(6×10⁴)
(5×6)(10⁷×10⁴)
30×10⁷⁺⁴
30×10¹¹
Since the constant cannot be greater than 10, move the decimal point to the left.
30×10¹¹
3.0×10¹¹
The decimal was moved by one space, so the constant must be multiplied by 10 the one power. The 10 to the eleventh power still needs to be multiplied as well.
3.0×10¹⁺¹¹
3.0×10¹²
Since two exponents with the same base are being multiplied, it can be simplified by adding the exponents. Therefore, the final answer is 3.0×10¹².
Answer:
two of them are possible which one is the correct
For every other number, you multiply by 2 and then add 3.
2 x 2 is 4, then 4 + 3 is 7, then 7 x 2 is 14, then 14 + 3 is 17...
