Answer:
95
Step-by-step explanation:
We have the expression q over 19 = 5 and are asked to solve for q.
We have a dillemma here, q is in a fraction, to solve, all we need to do is get rid of this fraction. Since 19 is the denominator, we can multiply it by both sides :
[tex]\frac{q}{19} = 5[/tex]
19 * 5
95
Therefore :
q = 95

-9 ÷ +3
Answers
Answer:
-3
Step-by-step explanation:
-9 divided by +3 can be written as -9 divided by 3, because when you have a positive number, you don't have to write a plus sign in front of it. Next, we can just do 9/3 and then add the negative sign to the result to get our answer. 9 divided by 3 is equal to 3, and when you add the negative sign, you get -3.

If using the method of completing the square to solve the quadratic equation
x²-10x – 15 = 0, which number would have to be added to "complete the
square"?
Answers
Answer:
For quadratic equations that cannot be solved by factorising, we use a method which can solve ALL quadratic equations called completing the square. We use this later when studying circles in plane analytic geometry.
Completing the square comes from considering the special formulas that we met in Square of a sum and square of a difference earlier:
(x + y)2 = x2 + 2xy + y2 (Square of a sum)
(x − y)2 = x2 − 2xy + y2 (Square of a difference)
To find the roots of a quadratic equation in the form:
\displaystyle{a}{x}^{2}+{b}{x}+{c}={0}ax
2
+bx+c=0,
follow these steps:
(i) If a does not equal \displaystyle{1}1, divide each side by a (so that the coefficient of the x2 is \displaystyle{1}1).
(ii) Rewrite the equation with the constant term on the right side.
(iii) Complete the square by adding the square of one-half of the coefficient of x to both sides.
(iv) Write the left side as a square and simplify the right side.
(v) Equate and solve.
Example 1
Find the roots of x2 + 10x − 4 = 0 using completing the square method.

Answer:

Step-by-step explanation:
Answer:
To determine the value of X, what you would need to do is to use a trigonometric ratio, that would make use of the value of x and the side length of 12. This can either be, sin 30 or cos 60. Both of them will enable you to solve for x.
The final value for x would be either
X = 12/Sin 30
X = 12/Cos 60
Compute these in your calculator and you will find the final value in these cases.

Answers
Answer:
y = 1x + 7
Step-by-step explanation:
The equation formula for this scenario is y = mx + b
m = slope
b = y-intercept
To find the slope, pick two points. I picked (2,9) and (4,11).
Subtract 11 from 9, you'll get 2.
Subtract 4 from 2, you'll get 2.
2/2 equals 1. The slope (m) = 1
To find the b, y-intercept, plot the points on a graph and see if the linear line across the y-intercept. For this case, the y-intercept is 7.
The equation is: y = 1x + 7

Jada sister Earns a commission. She makes 3.5 of them out she sells. Last week she sold, 7000 Worth of furniture. How much was her commission?
Answers
Answer:

Step-by-step explanation:
3.5% of 7000 = 0.035 × 7000 = 245
Jada has a stand in the marketplace where she sells ground cumin. Her weekly expenses are $300, and she sells her cumin at a fixed price per kilogram. If she sells 120 kilograms of cumin, her weekly net profit is $600.
Answers
Answer:
Step-by-step explanation:
The net profit of the marketplace is the difference between the revenue and the expenses. The revenue is the product of number of kilograms sold and the price per kilogram.
Profit = Revenue - Expenses
600 = 120x - 300
The value of x from the equation is 7.5. The answer therefore for the first question is $7.5. Then, the number of kilogram of cumin she needs to sell to cover the expenses is $300/$7.5 and that is equal to 40.

The area covered by a topic lie plant triples every year. By what factors does the are covered by the plant increase every month?
Answers
Answer:
16.67%
Step-by-step explanation:
If area triples every year :
This means that :
With an initial area of 10;
Area at the end of the year = 3 * 10 = 30
Percentage increase per year :
(30 - 10) / 10 * 100%
(20 / 10) * 100%
2 * 100%
= 200% per year
Therefore, monthly increase %
Yearly % increase ÷ number of months in a year
200% ÷ 12
= 16.666666%
= 16.67%

Step-by-step explanation:
every triangle all three angles equal 180 for a right triangle you know that one angle is 90 degrees for this triangle we know that another angle is 47 so
90+47 = 137 now we can take 180 - 137 = 43
so your third angle is 43
