Answer:If you are using a calculator, simply enter 770×100÷70, which will give you the answer.
Step-by-step explanation:
Y = mx + c
m = 2
y = 2x + c
At (5, 0)
0 = 2(5) + c
c = -10
y = 2x - 10
M = milk
C= cheese
X=meat
milk = 0.5c
meat = 4c
cheese = 1c
<span>4 +0.5 = 1c = 5.5c</span>
C= 42/5.5 = 7.64
X = 7.64 x 4 = 30.56
M =7.64 * 0.5 = 4.67
30.56 + 3.82 + 7.64 = approximately $42
Answer:
The Width = 65.44 inches
The Height = 36.81 inches
Step-by-step explanation:
We are told in the question that:
The width and height of an newer 75-inch television whose screen has an aspect ratio of 16:9
Using Pythagoras Theorem we known that:
Width² + Height² = Diagonal²
Since we known that the size of a television is the length of the diagonal of its screen in inches.
Hence, for this new TV
Width² + Height² = 75²
We are given ratio: 16:9 as aspect ratio
Width = 16x
Height = 9x
(16x)² +(9x)² = 75²
= 256x² + 81x² = 75²
337x² = 5625
x² = 5625/337
x² = 16.691394659
x = √16.691394659
x = 4.0855103303
Approximately x = 4.09
For the newer 75 inch tv set
The Height = 9x
= 9 × 4.09
= 36.81 inches
The Width = 16x
= 16 × 4.09
= 65.44 inches.
