Answer:
let length be b+5 and breadth be b
given,
perimeter of rectangle=150
or, 2(l+b) =150
or, 2(b+5+b)=150
or, 2b+5=150/2
or, 2b+5=75
or, 2b=70
therefore, b=35m
l=b+5
=35+5
=40m
Answer: (3, 8)
<u>Step-by-step explanation:</u>
- <u>x | y</u>
- <u>3 | 8</u>
- <u>6 | 6</u>
- <u>7 | 8</u>
- <u>9 | 12</u>
Notice that y=8 when x=3 and when x=7, so this is either a parabola or an absolute value function.
The axis of symmetry passes the midpoint of x=3 and x=7 so the axis of symmetry is x = 5.
(6,6) is given. It's mirror image <em>across the axis of symmetry</em> is (4, 6).
Similarly, (9, 12) is given. It's mirror image is (1, 12).
And (7, 8) is given. It's mirror image is (3, 8). This is the only pair available as given options for this question.
<em>Side note: Notice that the slope between (6, 6), (7, 8), and (9, 12) is the same (equal to 2) so this is the graph of an absolute value function.</em>
Answer:
The x coordinate would be 4.
Step-by-step explanation:
In order to find this, we'll make the y terms cancel. To do this, we need to multiply the whole second term by -1 and then add them together.
3x + 5y = 10
-x - 5y = -2
-----------------
2x = 8
Now that we have this, we can divide to get the answer.
2x = 8
x = 4
Answer:
<h2>15.5 units</h2>
Step-by-step explanation:
This problem is on the mensuration of flat shapes, this time a square shape.
we know that the area of a square is given as
area= length*length
area= l^2
from the problem the area is given as
area= 240 units^2
substitute area for the area in the equation and then we solve for length we have
240= l^2
squareing both sides we have
√240= l
l= 15.49 units
to the nearest hundreths it is
15.5 units
0.368 rounded to the nearest tenth is 0.4. To verify this, in order to round to the nearest tenth, you need to look at the hundredths place. In this case, that would be the 6. 6 is greater than 5 so the 3, the tenths place, goes up one number to 4. So your answer is 0.4.
