The correct answer is A
70/75 × 100 = 93.33333%
100% – 93.33333% = 6.66667% (to 1dp it's 6.7%)
Answer:
The constant of proportionality is option D i.e 5.
Step-by-step explanation:
Variation:
Variation problems involve fairly simple relationships or formulas, involving one variable being equal to one term. There are two types of variation i.e.
- Direct variation
- Inverse variation
Direct Variation:
Mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.
Example
where, k is constant of proportionality.
The above given example is of Direct Variation
∴ y = 5 x
∴ k = 5 = constant of proportionality.
Inverse Variation:
Mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.
Example
where, k is constant of proportionality.
Answer:
the combination of numbers must then be:
9.7 + 8.6 which results to 18.3
9.6 + 8.7 yields 18.3 as well.
LMK if I was wrong.
Yours Truly.
Answer:
Step-by-step explanation:
The equations are:
The two graphs intersect when:
To find the area under the curve for the first equation:
To find the area under the curve for the second equation:
To find the total area:
Simplifying the equation:
Note: The reason the area is equal to the area two minus area one is that the line, area 2, is above the region of interest (see image).
