Answer:

x=70

Step-by-step explanation:

Angle 1 will be 90° when it subtends a 180° arc. That means the sum of 100° and (x+10) must be 180°, so (x+10) = 80°.

We assume this is intended to mean ...

... (x +10)° = 80° . . . . . note the ° symbol added outside parentheses

... x +10 = 80 . . . . . divide by °

... x = 70 . . . . . . . . .subtract 10

_____

If the intent is (x+10°) = 80°, then x=70°.

Comment on the numbers here

Units need to be properly specified in problems of this nature. As written, we probably should assume that 10 is radians, and x is a large negative number, about -8.60374 (radians), or -492.958°.

A number of radians is a "pure number." It has no units. The term "radians" is used to signify that the number is considered to be an angle measure.

Answer:

He must start his journey by 11 AM

Step-by-step explanation:

Speed of Toshi while walking up the mountains is 1.5 kilometres per hour

Speed of Toshi while walking down the mountains = 2 * Speed of Toshi while walking up the mountains = 3 kilometres per hour

Time taken to travel 9 Km in the upward direction by Toshi = 9 Km/1.5 kilometres per hour = 6 hours

Time taken to travel 9 Km in the downward direction by Toshi = 9 Km/3 kilometres per hour = 3 hours

He will take total 6 hours + 3 hours = 9 hours to travel 18 Km distance

Thus, He must start his journey by 11 AM

aleksley [76]

Answer-

The price of gas will be $4.2

Solution-

Gas prices in shelby county = $3.00 per gallon

Market scientist predicts a 40% increase in the price of gas in the coming month.

So the new price will be,

$=3+(3\times \dfrac{40}{100})$

$=3+(3\times 0.4)$

$=3+1.2$

$=4.2$

Therefore, the price of gas will be $4.2

For this case we have the following functions:
f (x) = 3x + 4
g (x) = 2 ^ x - 1
The intersection with the y axis of the original functions is:
f (0) = 3 (0) + 4 = 0 + 4 = 4
g (0) = 2 ^ 0 - 1 = 1 - 1 = 0
The transformations that must be applied so that they have the same intersection with the y axis are:
f (x) - 3
g (x) + 1
Answer:
f (x) - 3
g (x) + 1
option 1
