Answer:
x = 10
missing angle = 83°
Step-by-step explanation:
These are supplementary angles meaning they have a sum of 180°.
8x + 3 + 97 = 180
8x + 100 = 180
8x + 100 - 100 = 180 - 100
8x = 80
x = 10
Substitute the value for the variable.
8(10) + 3
80 + 3
83
Answer:
A. $1500
Step-by-step explanation:
We need to find the countertop area, so let's calculate the areas of the rectangles that the problem broke the countertop into:
1. "1 rectangle has a base of 70 inches and height of 20 inches"
The area of a rectangle is denoted by: A = bh, where b is the base and h is the height. Here, b = 70 and h = 20, so the area is: A = 70 * 20 = 1400 inches squared
2. "The other rectangle has a base of 20 inches and height of 30 inches"
Again, use A = bh: b = 20 and h = 30, so A = 20 * 30 = 600 inches squared
Add up these two areas: 1400 + 600 = 2000 inches squared.
The problem says that the cost is $0.75 per square inch, so multiply this by 2000 to get the total cost of 2000 square inches:
2000 * 0.75 = $1500
Thus, the answer is A.
Hope this helps!
Answer:
not sure but i think 64 ?
(40 - x) ÷ 2
this is because we first deduct the difference
The function rule for the equation y = -5x - 1 is
(x,y) ⇒ (0,-1) , (-1,4) , (3,-16)
<h3>What is dependent variable and independent variable ?</h3>
In a mathematical equation independent variable is set by us to examine the give equation or function how it is behaving or it's value for a specific value being set by us.We can also think of independent variable as the input to a function and dependent variable as the output.
According to the given question
y = -5x -1 the table is illustrated below
x -2 -1 0 1 2 3
y 9 4 -1 -6 -11 -16
