Answer:
Step-by-step explanation:
Therefore, three consecutive integers that add up to 297 are 98, 99, and 100. We know our answer is correct because 98 + 99 + 100 equals 297 as displayed above.
Answer: 28
Step-by-step explanation:
there are 3 boys for every 4 girls, so 4 times 4 is equal to 16. Now just multiply 3 times 4. 16 + 12 = 28.
Answer:
15%
Step-by-step explanation:
The price of the tablet was increased from $180 to $207.
Increase = $207 - $180
= $27
Therefore,
Percentage increase = increase/initial amount x 100%
That’s $27/$180 x 100%
0.15 x 100
15%
The percentage increase was 15%
Answer:
i think its x
Step-by-step explanation:
The value of cos 67.4° is 5/13.
According to trigonometric identities used in mathematics, sin of an angle is equal to cos of 90 - the given angle. Mathematically, this means that, suppose we have an angle x, then-
sin(90 - x) = cos x
Here, we are given that sin 22.6° = 5/13. As we can observe that (90 - 67.4) is equal to 22.6, and we need to find the value of cos 67.4° only. Thus we can write the given equation as follows-
sin22.6° = sin(90 - 67.4°)
= cos 67.4°
Thus, sin 22.6° = cos 67.4°
Hence, cos 67.4° = 5/13
Thus, the value of cos 67.4° comes out to be 5/13.
