One is 48, the other is 90 since it is supplementary to the other right angle. All three angles of a triangle always add up to 180 degrees.

So 48+ 90 + x = 180
x = 42 degrees

a wheel has a diameter of 15cm. The wheel travels 50 metres. How many revolutions does the wheel complete?
TEA [102]

Answer:

106

Step-by-step explanation:

The diameter of the wheel is 15 cm or 0.15 m.

The circumference of the wheel is 0.15π m ≈ 0.47 m.

So the wheel moves 0.47 m with each revolution.

The wheel travels 50 m, so the number of revolutions is:

(50 m) / (0.47 m/rev) ≈ 106 revolutions.

Show the following conjectures are false by finding a counterexample.
Julli [10]

''All prime numbers are odd."

That is incorrect because if we consider the smallest odd number, 2, is an even number. We can say that except 2, all prime numbers are odd.

14. section is wrong. For example, both numbers can be negative, so when we multiple these two, it will equals a positive value.

At how many points does the graph of the function below intersect the x-axis?
Angelina_Jolie [31]
Setting y=0, we can solve the quadratic equation or factor the polynomial to
(5x-1)•(5x-1) = 0
(5x-1)^2 = 0
5x-1=0
x=1/5 or 0.2
So there is only one root and the function intersects the x-axis at only one point.
The answer is B. 1.
