I'll only answer the first question, 'The data representation is useful because it tell and shows you what industry, what is the yearly cost and the highest qualifications.'
Answer:
It’s correct
Step-by-step explanation:
You‘ve got the first angle correct! You‘ve got the second angle correct. The third angle is also correct! angle.
Now the third angle has a way of Tricken ya! So heres a way to solve:
5 x 20= 100
100-40= 60
GOOD JOB! have a good night!
Answer:
(There's a confusion here, is x 2 x times 2? The answer and explanation are based on x multiply by 2)
y = -8
Step-by-step explanation:
Substitution Method-
y = x 2 - 4
x = -2
y = (-2) 2 - 4
PEMDAS - parentheses; exponents; Multiplication & Division; Addition & Subtraction
we are going to multipl -2 and 2 together ---> -4
y = -4 - 4
Same sign add, different sign subtract.
Same sign keep the sign, different sign keep the larger.
y = -8
Please mark brainliest!
Hope this helps!
Thank you,
Have a great day!
Answer:
In the graph we can find two points, lets select:
(2, 15) and (4, 30)
Those are the first two points.
Now, for two pairs (x1, y1) (x2, y2)
The slope of the linear equation y = s*x + b that passes trough those points is:
s = (y2 - y1)/(x2 - x1)
So the slope for our equation is
s = (30 - 15)/(4 - 2) = 15/2
then our linear equation is
y = (15/2)*x + b
now we can find b by imposing that when x = 2, y must be 15 (for the first point we selected)
15 = (15/2)*2 + b = 15 + b
b = 15 - 15 = 0
then our equation is:
y = (15/2)*x
Where we used a division and a multiplication.
For this case we can model the problem as a rectangle triangle.
We have two sides.
We want to find the hypotenuse of the triangle.
We have then:
h = root ((a) ^ 2 + (b) ^ 2)
Substituting values we have:
h = root ((6) ^ 2 + (8) ^ 2)
h = root (36 + 64)
h = root (100)
h = 10
Answer:
If you could walk straight from one school to the other, the 2 schools would be at:
h = 10 blocks
