Answer:
1.5 km
Step-by-step explanation:
Length of pool = 25m
no.of lengths. = 60
Total length of he swim s = 25m* 60
= 1500m
You know , 1000m = 1km ,
so,
He swims 1500m/1000m
= 1.5 km
Since both are on the line y=10, the distance between the points is their difference in x-coordinates: 15 - (-30) = 45 units.
Answer:
d. 15, 30, 135
Step-by-step explanation:
A triangle's interior angles on a flat surface add up to 180 degrees.
a. 90 * 3 = 270 != 180
b.(80 * 2) + 200 = 360 != 180
c.40 + 50 + 60 = 160 != 180
d.15 + 30 + 135 = 45 + 135 = 180, so it has to be d.
Example -
4x2<span> + 6x + 5</span>
This polynomial has three terms. The first one is 4x2, the second is 6x, and the third is 5
The exponent of the first term is 2
The exponent of the second term is 1 because 6x = 6x1
The exponent of the third term is 0 because 5 = 5x0
What? 5x0<span> = 5?</span>
Well, anything with an exponent of 0 is always equal to 1
So, 5x0<span> = 5 × x</span>0<span> = 5 × 1 = 5</span>
Since the highest exponent is 2, the degree of 4x2<span> + 6x + 5 is 2</span>
