Answer:
the weight of the steel beam and steel beam length
let y be weight and x be length of it
y=ax
where a is the constant
we can find it if we have two sets of values of y and x
Answer:
y=5x^2+30x+58
y=−x^2+8x−26
Step-by-step explanation:
Vertex form is y = a(x – h)^2 + k, where (h, k) is the vertex.
Standard for is Ax + By = C
simply rewrite the equations using the formulas
1/1 = 1
1/2 = 0.5
1/3 = 0.3
1/4 = 0.25
1/5 = 0.2
vvvvvvvv
1/6 = 0.16
^^^^^^^^^
The correct answer is 82% of 50 (41) / 170% of 30 (51) /65% of 80 (52)
Explanation:
The first step to know whether a value is greater than another is to find the value each percentage represents depending on the total. This process is shown below.
1. 65% of 80- This implies 80 is 100% and 85% needs to be found. Use the following formula:
80 / 100 = 0.8 x 65 = 52 or the total number divided by 100 and multiplied by the percentage you want to know
2. 82% of 50 - Repeat the same process
50 / 100 = 0.5 x 82 = 41
3. 170% of 30
30 / 100 = 0.3 x 170 = 51
4. Finally organize the values
82% of 50 (41)
170% of 30 (51)
65% of 80 (52)
