As part of a screening process, computer chips must be operated in an oven at 145 °C. The starting temperature is 25 °C. After 1

DaniilM [7]

Answer:

30 minutes will it take to reach its specified operating temperature from 25°C.

Step-by-step explanation:

Initial Temperature of oven = 25°C

Time taken by oven to reach 85°C temperature = 15 minutes

We have to find time taken by oven to reach at temperature of 145°C

Increase in temperature in 15 minute = 85 - 25 = 60°C

So, Time take by oven to increase 60°C temperature = 15 min

Time take by oven to increase 1°C temperature = $\frac{15}{60}=\frac{1}{4}\:minutes$

Temperature we have to increase = 145 - 25 = 120°C

Time take by oven to increase 120°C temperature = $\frac{1}{4}\times120=30\:minutes$

Therefore, 30 minutes will it take to reach its specified operating temperature from 25°C.

The endpoints of cd are c(3,-5) and D(7,9). The coordinates of the midpoint m of CD are

-BARSIC- [3]

Answer: M(5,2)

Step-by-step explanation:We use the midpoint rule:

We just have to find the arithmetic mean of the x and y-coordinates.

The endpoints of CD are given as C(3,−5) and D(7, 9).

We substitute these values to get:

Therefore the coordinates of the midpoint M of CD are (5,2) and if i'm not good at explaining here ya go :)

X-3 (2x-7)=76 what is x

liq [111]

x - 3(2x - 7) = 76
x - 3(2x) - 3(-7) = 76
 x - 6x + 21 = 76
 -5x + 21 = 76
 - 21 - 21
 -5x = 55
 -5 -5
 x = -11
