A rectangular television's length is 3 inches more than twice the width. The perimeter of the TV is 144 inches. What is an equation to find the width?
Answer:
52 inches
Step-by-step explanation:
We know that the perimeter of a rectangle is equivalent to twice the width plus twice the length.
P
=
2
w
+
2
l
Since the length is 18 more then the width, we can rewrite
l
as
(
w
+
18
)
.
Plug in that in place of
l
and plug in 244 for the perimeter, and you can solve for the width.
244
=
2
w
+
2
(
w
+
18
)
Distribute:
244
=
2
w
+
2
w
+
36
Combine like terms:
244
=
4
w
+
36
Subtract 36 from each side:
208
=
4
w
Divide each side by 4:
52
=
w
Angles use the diagram at the right (HELP PLEASE)
aughhhh i suck at this topic
Answer:
x = 18
Step-by-step explanation:
The given angle is a right-angled triangle.
Such triangles have an angle that equals 90°.
The square attached at the base represents 90°. [Whenever you such a square between two sides, simply put the angle between those sides equal to 90.]
So, the points we know about this triangle:
One angle is = 90Another angle given in the question is 72°.*Property*
The sum of all angles in a triangle = 180
==> 90 + 72 + x = 180
==> 162 + x = 180
==> x = 180 - 162
==> x = 18

Answer:
1/2 and 1/10
Step-by-step explanation:
needs to be explained
Answer:
B
Step-by-step explanation:
92 x 49 = 4508 which is the area of the rectangle because you do length times height.
To Find the area of a circle you need to find the radius which is half of your diameter which is 20
20/2=10
Then for the area of your circle the formula is Pie r squared (π r^2)
Plug into your calculator π x 10^2 to get 314.16
Finally you subtract 314.16 from 4508 to get your answer 4193.84
Since on the sheet it looks like you have to round it would just round up to 42,000ft^2 which is B

Step-by-step explanation:
I did it in my head but I'm sure it's correct cause the first two points are on the same x-axis but the numbers for the y-axis are different which means that the answer has to have one of the same y-axis numbers from one of the first two y-axes this process singles it out to (7, 27).

The temperature after 2 hours, 5 hours and half an hour are respectively;
-6°C, -15°C and -1.5°C
How to calculate tempoerature change?We are told that the current temperature is 3°C. If the current falls at a constant rate of 3°C per hour. Then;
1) After 2 hours, temperature will be;
0 - (2 * 3) = -6°C
2) After 5 hours, temperature will be;
0 - (3 * 5) = -15°C
3) After half an hour, the temperature will be;
T = 0 - (1/2 * 3)
T = -1.5°C
4)At 1 hour ago, the temperature is;
T = 0 + (1 * 3) = 3°C
5) At 3 hours ago, the temperature is;
T = 0 + (3 * 3)
T = 9°C
6) At 4.5 hours ago, the temperature is;
T = 0 + (3 * 4.5)
T = 13.5 hours

Step-by-step explanation:
How do I solve this proportional problem?
Phone 1 has the length of 2.6 and height of 5.4
Phone 2 has the height of 6.21 and the length of _____
What is the length of the Phone 2? Keep in mind that the answer is gonna to proportional.
The length of the phone 2 is 2.99 units.
Given data:
Phone 1 has the length of 2.6 and height of 5.4
Phone 2 has the height of 6.2 units.
The length of the phone 2 is represented as L.
So, the lengths and heights are in proportion.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
So, [tex]\frac{6.2}{5.4} =\frac{L}{2.6}[/tex]
On cross multiplying:
L = 1.15 * 2.6
L = 2.99 units.
Hence, the length is 2.99 units.
