Answer:

Step-by-step explanation:

2. 2(3x+4)=10

6x+8=10

6x+8-8=10-8

6x=2

x= 1/3

3.  2x + 7 = 5x + 16

7 + 2x = 5x + 16

7 + 2x = 16 + 5x

7 + 2x + -5x = 16 + 5x + -5x

7 + -3x = 16 + 5x + -5x

7 + -3x = 16 + 0

7 + -3x = 16

7 + -7 + -3x = 16 + -7

0 + -3x = 16 + -7

-3x = 16 + -7

-3x = 9

x = -3

4.   x/3-8=-2

x/3=6

x=18

5. 3x-6=-12

3x-6+6=-12+6

3x=-6

x=-2

sorry but i cannot solve 1 or 6 because i am quite stupid

What is the value of the x in the equation? x+1/8=3/4​
creativ13 [48]

Answer:

x = 5/8

Step-by-step explanation:

Isolate the variable by subtracting 1/8 from both sides:

3/4 - 1/8 = 5/8

Now, the equation is:

x = 5/8

Therefore, the answer is 5/8

Suppose that demand in period 1 was 7 units and the demand in period 2 was 9 units. Assume that the forecast for period 1 was fo
Zepler [3.9K]

Answer:

Step-by-step explanation:

Forecast for period 1 is 5

Demand For Period 1 is 7

Demand for Period  2 is 9  

Forecast  can be given by

F_{t+1}=F_t+\alpha (D_t-F_t)

where

F_{t+1}=Future Forecast

F_t=Present\ Period\ Forecast

D_t=Present\ Period\ Demand

\alpha =smoothing\ constant  

F_{t+1}=5+0.2(7-5)

F_{t+1}=5.4

Forecast for Period 3

F_{t+2}=F_{t+1}+\alpha (D_{t+1}-F_{t+1})

F_{t+2}=5.4+0.2\cdot (9-5.4)

F_{t+2}=6.12

Through how many radians do the minute hand and the hour hand move between 1:00 p.m. and 1:45 p.m. (on the same day)? ​
timofeeve [1]

Answer:

π/8 radians

Step-by-step explanation:

THIS IS THE COMPLETE QUESTION

In 1 h the minute hand on a clock moves through a complete circle, and the hour hand moves through 1 12 of a circle. Through how many radians do the minute hand and the hour hand move between 1:00 p.m. and 1:45 p.m. (on the same day)?

SOLUTION

✓If the minute hand on a clock moves through complete circle in 1 hour, then it means that it goes through a circle and angle of circle in radians is 2π.

Between 1:00 p.m. and 1:45pm in the same day we have 45 minutes i.e (1.45 pm -1pm)

Within the 1hour minutes, the hand can move with complete cycle of 2π radians

Then At time t= 45minutes

Angle through the circle at 45 minutes= 45/60 ×2π radians

= 3π/2 radians

And if the hour hand goes through a complete cycle 1/12 as told in the question we have 1/2 × 2π radians

For t=45 minutes

Then 1/12 × 2π ×45/60

= π/8 radians

Hence, the minute hand and the hour hand move π/8 radians between 1:00 p.m. and 1:45 p.m.

stepan [7]
ANSWER:
There are 30 geese.
STEP-BY-STEP EXPLANATION:
Let y be the total no. of animals
Share= ratio/total ratio X total
50= 5/8 X y
50= 5y/8
50 X 8= 5y
y= 400/5
y= 80
The total no. of animals is 80
80-50=30 ans.
