Answer: 739.32in

Step-by-step explanation:

Since we are informed that originally the TV was 32 inches (across the diagonal) and had an area of

446.38in while thee new TV is 53 inches across the diagonal.

The area of the new TV would simply be calculated as:

= (53 × 446.38) /32

= 23658.14 / 32

= 739.32in

Radha and her 5 friends took part in a marathon relay. they ran a total distance of 42 km and 195 m. if each friend ran 7 km, ho

Mariulka [41]

Let the total distance travelled by Radha be x .

Total number of friend = 5

total distance travelled by each friend is 7 km

$\\$

so,

$\\$

$\large{\mapsto{x\:+\:7\:×\:5\:=\:42.195}}$

$\large{\mapsto{x\:+\:35\:=\:42.195}}$

$\large{\mapsto{x\:=\:42.195\:-\:35}}$

$\large{\mapsto{x\:=\:7.195\:km}}$

as per our assumption .

that total distance travelled by Radha is x

so total distance travelled by Radha is 7.195 km

Are the equations 2x - y = - 4 and 3x + y = -1 dependent, independent or neither

steposvetlana [31]

Answer:

From the above calculations, it is clear that the consistent system has exactly one solution i.e. x = -1, y =2, therefore, it is independent.

Step-by-step explanation:

Given the system of equations

$\begin{bmatrix}2x-y=-4\\ 3x+y=-1\end{bmatrix}$

$\mathrm{Multiply\:}2x-y=-4\mathrm{\:by\:}3\:\mathrm{:}\:\quad \:6x-3y=-12$

$\mathrm{Multiply\:}3x+y=-1\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:6x+2y=-2$

$\begin{bmatrix}6x-3y=-12\\ 6x+2y=-2\end{bmatrix}$

$6x+2y=-2$

$-$

$\underline{6x-3y=-12}$

$5y=10$

so the system of equations becomes

$\begin{bmatrix}6x-3y=-12\\ 5y=10\end{bmatrix}$

solving 5y = 10 for y

$5y=10$

Divide both sides by 5

$\frac{5y}{5}=\frac{10}{5}$

simplify

$y=2$

$\mathrm{For\:}6x-3y=-12\mathrm{\:plug\:in\:}y=2$

$6x-3\cdot \:2=-12$

$6x-6=-12$

Adding 6 to both sides

$6x-6+6=-12+6$

$6x=-6$

Divide both sides by 6

$\frac{6x}{6}=\frac{-6}{6}$

$x=-1$

Therefore, the solution to the system of equations be:

$x=-1,\:y=2$

From the above calculations, it is clear that the consistent system has exactly one solution i.e. x = -1, y =2, therefore, it is independent.

pam read 5 pages of a mystery book in 3 minutes. if she continues to read at the same rate how many hours will it take her ro re

Amanda [17]

Pam would read 235 pages in 141 minutes or 2hrs and 21min.
Divide 3 from 5 to get the time it takes her to read 1 page which is 0.6 . Now multiply .6 by the number of total pages (235) to find the time it takes, which would be 141 minutes, 2.35 hours, or 2 hours and 21 minutes (whichever you prefer) ( 3/5 = .6 × 235 = 141 )
