Answer:
£295.2
€1.39
Step-by-step explanation:
€1 = £0.72
a) €410= £0.72*410= £295.2
b) £1= €1/0.72= €1.39
The answer is 79 and 80.
x - the number of the first locker
x + 1 - the number of the consecutive locker
Their sum is 159.
x + x + 1 = 159
2x + 1 = 159
2x = 159 - 1
2x = 158
x = 158 / 2
x = 79
x - the number of the first locker: x = 79
x + 1 - the number of the consecutive locker x + 1 = 79 + 1 = 80
Answer:
k=8
Step-by-step explanation:
divide both sides by 11 to get nine
then subtract 1 from both sides to get
8
Answer:
On the science test the point ( 0 , 424 ) the intercepts is bigger
Step-by-step explanation:
The relation hours spend vs science test score is
y = 6.5*x + 424
And the relation hours spend vs Maths test score is
y = 7.2*x + 34.7
Making x = 0 ( student does not study at all ) we get:
For science score test woul be
y = 0 + 424
In case of maths
y = 0 + 34.7
That mean student without studying will get better score in science.
The point ( 0 , 424) ( science ) represents the interception with y axis
in Maths case such point is ( 0 . 34.7)
Answer:
(7, 24, 26)
Step-by-step explanation:
A Pythagorean triple must have an odd number of even numbers. The triple (7, 24, 26) is not a Pythagorean triple.
_____
<em>Additional comment</em>
For an odd integer n, a triple can be formed as ...
(n, (n²-1)/2, (n²+1)/2)
That is, the following will be Pythagorean triples.
- (3, 4, 5)
- (5, 12, 13)
- (7, 24, 25)
- (9, 40, 41)
- (11, 60, 61)
Another series involves even numbers and numbers separated by 2:
(2n, n²-1, n²+1)
- (8, 15, 17)
- (12, 35, 37)
- (16, 63, 65)
In this list, if n is not a multiple of 2, the triple will be a multiple of one from the odd-number series.
It is a good idea to remember a few of these, as they tend to show up in Algebra, Geometry, and Trigonometry problems.
