y = [? ]
Enter
Answer:
90°
Step-by-step explanation:
2x = 60° and x = 30 the sum of interior angles in a triangle is = 180°
60° + 30° + y = 180°
y = 90°
find the value of y
Answer:
y = 60
Step-by-step explanation:
The figure given is a parallelogram;
opposite angles in a parallelogram are equation;
So;
<POR = <PQR
<POR = 2y - 60
<PQR = y
Therefore;
2y - 60 = y
-60 = y - 2y
-60 = -y
y = 60

The number of sheets of paper available for making notebook is 75,000. Each sheet makes 8 pages of a notebook. Each notebook contains 200 pages. How many notebooks can be made from the paper available?
Each sheet makes 8 pages,
Therefore, total no. of pages = 75,000 × 8 = 600,000
No. of pages for each book = 200
Therefore, no. of notebooks made = 600,000 ÷ 200
= 3000

Answer:
123.5
Step-by-step explanation:
Answer:
123.5
Step-by-step explanation:
To round 123.456 to the nearest tenth consider the hundredths’ value of 123.456, which is 5 and equal or more than 5. Therefore, the tenths value of 123.456 increases by 1 to 5.

explain the steps to finding the vertex of g(x) = 3x2 + 12x + 15
Answer:
Vertex: (-2, 3)
Step-by-step explanation:
We first have to find the x - variable of the vertex point.
The formula to find the x - variable is x = -b/ 2a.
[tex]3x^{2} + 12x + 15[/tex]
a b c
Substitute the values into the formula.
x = - 12 / 2(3)
x = - 12 / 6
x = - 2 < - This is the x - variable
Now we have to find the y - variable of the vertex point.
To find the y - variable, we have to substitute the x value into the original equation ([tex]3x^{2} + 12x + 15[/tex]).
g(x) = y
[tex]y = 3(-2)^{2} + 12(-2) + 15\\[/tex]
[tex]y = 3(4) - 24 + 15[/tex]
[tex]y = 12 - 24 + 15[/tex]
[tex]y = - 12 + 15[/tex]
[tex]y = 3[/tex]
So, now that we have the x and y values, we can find the vertex which is (-2, 3).
Hope this helps!

It should be the answer but you may double check on a calculator.
using the function below, calculate f(4).
Answer:
D. 8
Step-by-step explanation:
Using the graph of the function above, f(4) can be easily determined by tracing the corresponding coordinate of x = 4. When x = 4, on the x-axis, y = 8 on the y-axis.
The value of f(4), simply means, what is the value of y when x = 4.
Thus, the value of f(4) = 8.
The right answer is D. 8.

The total of your dinner bill plus tip is $16.00. You left a $3.20 tip. Write an expression to describe this situation.
Answer:
y= 16x - 3.2
Step-by-step explanation:
The expression for the given situation will be $16-$3.20 = $12.8, where $12.8 is the cost of dinner only.
What is an expression?An expression in maths is a sentence with a minimum of two numbers or variables and at least one maths operation.
Given that, The total of your dinner bill plus tip is $16.00. You left a $3.20 tip, we need to create an expression for this information,
The total cost = $16
Given for tip = $3.20
The dinner will cost = $16-$3.20 = $12.8
Therefore, the expression can be $16-$3.20 = $12.8
Hence, The expression for the given situation will be $16-$3.20 = $12.8, where $12.8 is the cost of dinner only.
