Answer:
y = 90°
Step-by-step explanation:
- 110° is the measure of exterior angle of bigger triangle.
- -> (x + x) + 70° = 110° (By exterior angle theorem)
- y is the measure of exterior angle of smaller triangle.
- -> y = x + 70° (By exterior angle theorem)
Multiplying 5 to the first fraction we get 15/25+1/25=16/25
Answer:
12 blueberries, 4 strawberries
Step-by-step explanation:
For every 3 blueberries, there is 1 strawberry. So 3 + 1 = 4
As there are a total of 16 berries in the bowl, 16/4 = 4 so there are 4 lots of "3 blueberries and 1 strawberry".
Therefore, there are 3 x 4 = 12 blueberries
1 x 4 = 4 strawberries
Answer:
The rate of the slower car is 69km/hr
Step-by-step explanation:
Please kindly check the attached files for explanation.
We all are familiar with (x,y) coordinate plane where some lines or curves are drawn. These curves are drawn or made up using some (x,y) points. These values of (x,y) points satisfy the equation of curves.
The equation of x and y variables is called a Relationship. Now, a Function is a "special relationship of x and y variables" where each input x has a single answer for output y.
In other words, we can say any relation y=f(x) would be a "Function" if and only if each value of x input give us a unique value of y output from the equation. No two values of y can be output of same x-value input.
For example:- y = f(x) = 2x is a Function because each value of x would give unique answer for y. x=4 gives y=8.
Another example is:- y = f(x) = √x is "not a function" because one-value of x would give two answers of y. x=4 gives y= -2 and y=2.
