Answer:-3
Just simplify the equation and you will x=-3
Answer:
The length of one leg of the triangle is 22 units
Step-by-step explanation:
The complete question in the attached figure
Let
x ----> the length of one leg of the triangle
we know that
In the right isosceles triangle of the figure
The cosine of angle of 45 degrees is equal to the adjacent side to angle of 45 degrees divided by the hypotenuse
---> equation A
----> equation B
equate equation A and equation B and solve for x


therefore
The length of one leg of the triangle is 22 units
Answer:
a) 300m
b) 15 miles
Step-by-step explanation:
a) 1 : 30 000
= 1x 30 000
= 30 000cm
= 30 000cm/ 100 Representing in metres
= 300m
b) 1 : 6
= 1x 2.5 : 6x 2.5
= 2.5 : 15
= 15 miles
Answer:
ranges from 2890 miles to 5780 miles.
Step-by-step explanation:
Let us call
the number of miles the car travels, and
the number of gallons of gas that are used, then we have the relationship
<em>(this says the car travels 17 miles for each gallon of gas).</em>
Now, when
, we have


and when
, we have


So, when
goes from 170 to 340,
goes from
to
.
Therefore, when
ranges from 170 to 340 gallons, the distance traveled ranges from 2890 to 5780 miles.
