Answer:
7/6
Step-by-step explanation:
p=3/4*q
q=14/9*r
so p=3/4*14/9r=7/6r
Which of the following is written as a rational function
The function written in the rational form is, C. F(x) = (x - 5)/3x
What are rational numbers?Rational numbers are subsets of real numbers which can be written in the form of p/q, where q ≠ 0. As at q = 0 it is undefined.
Similarly, A rational expression is also written in the form of p/q, where p and q are algebraic expressions and q ≠ 0.
From the given options, F(x) is written in the form p/q,
Where, p = x - 5 and q = 3x.
Therefore, The rational function is, F(x) = (x - 5)/3x, where x ≠ 0.
As at x = 0 the function is undefined.

Steve played a car race game. He gained some points, lost 27 points, and
finished with less than 400 points. Which of the following inequality
represents the given situation?
A.)X - 400 < 27
B.)x + 27 < 400
C.)X - 27 > 400
D.) X - 27 < 400
According to the information we can infer that the correct inequality that represents the given situation is D.) X - 27 < 400.
Which inequality does represent the given situation?Let's break down the information provided: Steve gained some points, lost 27 points, and finished with less than 400 points. To represent the number of points Steve had initially, let's use 'X'.
After gaining some points, his total would be X + G, where G represents the gained points.After losing 27 points, his total would be X + G - 27.Since he finished with less than 400 points, we can express this as X + G - 27 < 400.
Simplifying the equation, we get X - 27 < 400.According to the above we can conclude that the correct inequality that represents the given situation is D.) X - 27 < 400.

WILL MARK BRAINLIEST!! Multiply. −1/2⋅3/4 a)−2/3 b) −3/8 c) 3/8 d)2/3
Explanation:
When multiplying fractions, we multiply the numerators together, and the denominators are handled separately.
The numerators in this case are -1 and 3. They multiply to -3
The denominators multiply to 2*4 = 8
So that's how we end up with -3/8 as the final answer
This fraction cannot be reduced any further, because 3 and have 8 no factors (other than 1) in common.
Resolve the expression [tex]\frac{(x-2)}{(x^{2} +1)(x-1)^{2} }[/tex] into the simplest partial fractions
The partial fraction expansion will look like
(x - 2)/((x ² + 1) (x - 1)²) = (ax + b)/(x ² + 1) + c/(x - 1) + d/(x - 1)²
Get everything in terms of a common denominator, and compare the numerators on both sides:
x - 2 = (ax + b) (x - 1)² + c (x ² + 1) (x - 1) + d (x ² + 1)
Expand the right side:
x - 2 = (ax + b) (x - 1)² + c (x ² + 1) (x - 1) + d (x ² + 1)
x - 2 = (a + c) x ³ + (-2a + b - c + d) x ² + (a - 2b + c) x + b - c + d
Match up the coefficients and solve the resulting system of equations:
a + c = 0
-2a + b - c + d = 0
a - 2b + c = 1
b - c + d = -2
==> a = -1, b = -1/2, c = 1, d = -1/2
So the expansion into partial fractions is
(x - 2)/((x ² + 1) (x - 1)²) = (-x - 1/2)/(x ² + 1) + 1/(x - 1) - 1/(2 (x - 1)²)
… = -(2x + 1)/(2 (x ² + 1)) + 1/(x - 1) - 1/(2 (x - 1)²)

find the area of the right triangle
Answer:
the area of right angle is 1.5×2.5=3.75
Answer:
1.5 units^2
Step-by-step explanation:
If we say that the missing side is x, we can use the pythatgorean theorem to find it.
1.5^2 + x^2 = 2.5^2 => 2.25 + x^2 = 6.25 => x^2 = 4 => x=2
The area of a triangle is hieght * base * 1/2 => 1.5 * 2 * 1/2 = 1.5
the ratio of corresponding side of similar triangles is 5:2, then find the ratio of their areas
Answer:
25:4
Step-by-step explanation:
The ratio of the sides is 5:2
The ratio of the areas is the scale factor squares

How much of salt would you get if you evaporate all water from:
375g of a 12% salt solution

Answer:
45g
Step-by-step explanation:
The amount of salt left once the whole water is evaporated can be calculated as follows
= 12% × 375
= 12/100 × 375
= 0.12×375
= 45
Hence 45g of salt is left after the evaporation of water
Answer:
45g

1/7= 7 ) 1 (, the basic definition of division
which are partcial products
for 34 x 28
Answer:
952
Step-by-step explanation:
34 = (30 + 4)
28 = (20 + 8)
34 x 28 = (30 + 4) x (20 + 8)
34 x 28 = 30 x 20 + 30 x 8 + 4 x 20 + 4 x 8
34 x 28 = 600 + 240 + 80 + 32
34 x 28 = 952

. A research study about test anxiety will measure the change in heartrate of the test-taker. The researcher randomly assigns participants into one of two groups, either the Test group or the No-test group (where the first group takes a timed test and the second group reads for the same amount of time). What is the operational definition of the independent variable
Answer:
Timed test.
Step-by-step explanation:
An operational definition gives exactly what the independent variable means and its mode of measurement. The Independent variable is the variable in a research or experimental study which causes a change in the the measured variable. Hence, the independent variable is the predictor variable. In the study above, the independent variable is the timed test which is used to observe changes in the heart rate of the test taker (test anxiety). The change innheartrate of the test taker is the dependent variable.
