Answer:
Step-by-step explanation:
First we need to rewrite 3x-5y=8 in slope-intercept form.
The slope of this line is
The line perpendicular to this line will have a slope that is the negative reciprocal of 3/5, which is
This line passes through (3,7).
The equation is given by:
We substitute the point and slope to get:
We multiply through by 3 to get:
Expand to obtain:
There are 1760 yards in a mile.
It would take the bee (400/(20*1760)*60*60)=40.909 seconds
If my calculations are correct
64x15,18 C is the right answer
Answer:
14. 104 degree
15. 23.5 degree
16. -4 degree
Step-by-step explanation:
14. x+6 = 110
15. 46+4x+40 = 180
16. 62-2x+90-5x = 180
Caroline needs 1 suit, 1 overcoat, and 1 pair of shoes for an outfit. To find the number of different outfits, we can multiply the number of options for each group. 6 x 3 x 4 = 72 outfit options.
We can also think about it logically. For each suit, they have 3 different coats to wear. For each suit and coat combination, they have 4 different pairs of shoes to wear. So for each suit, there are 3 x 4 = 12 coat/shoe combinations. Since there are 6 different suits, they have 6 x 12 = 72 options.
