The miles he traveled by plane is nine times greater than the miles traveled by automobile. If the total is 600 miles, then the total distance traveled by automobile would be 60 miles, making the total traveled by airplane 540 miles.
Step-by-step explanation:
To find a set of 3 leg lengths that will form a right-angled triangle, the square of the largest leg must be equal to the sum of the squares of the other 2 legs.
We try out all the options:
39² = 1521, 15² + 36² = 1521.
12² = 144, 8² + 4² = 80.
17² = 289, 13² + 9² = 250.
Since 39² equals 15² + 36², option A is the correct answer.
Answer:
<u>50</u>
Step-by-step explanation:
<u>Changing into complex form:</u>
(6 + 8i) * (3 - 4i)
= 18 - 24i + 24i - 32 (i^2)
= 18 - 32(-1)
= 18 + 32
= <u>50</u>
Answer:
Step-by-step explanation:
2y+4=10
we will subtract 4 from both sides
2y=10-4
2y=6
y=3
Answer:
If an image of a triangle is congruent to the pre-image, then the scale factor of the dilation must be n = 1. Dilating an image with a dilation factor of 1 will result to the same image and that ensures the congruency between the pre-image and the dilated image.
