Answer:
PQ = 40
Step-by-step explanation:
First, set up a proportion:
[tex]\frac{12}{16} =\frac{30}{x}[/tex]
Then, cross-multiply and solve:
[tex]12x = 16(30)[/tex]
[tex]12x = 480\\\\\frac{480}{12x} \\\\PQ = 40[/tex]

what two numbers multiply to 56 and add to -15
Answer:
-7 and -8
Step-by-step explanation:
because 7 times 8 equals 56 and negative times a negitive equals a positive and -7 added to -8 equals -15
The pair of numbers which fulfill the given condition 2.6 & -1.76
and -17.6 & 2.6.
What is a quadratic equation ?An equation is quadratic in form if it can be written in the form of ax + bx + c = 0, where a, b, and c are constants and x is the variable.
Let x and y be the two numbers we're trying to find. We know that:
x * y = 56 (equation 1)
x + y = -15 (equation 2)
y = -15 - x (equation 3)
Substituting equation 3 into equation 1, we get:
x * (-15 - x) = 56
-x² - 15x + 56 = 0
x² + 15x - 56 = 0
Using the quadratic formula, we get:
x = (-b ± √(b² - 4ac)) / 2a
where a = 1, b = 15, and c = -56.
Substituting the values, we get:
x = (-15 ± 20.2) / 2
x = (-15 + 20.2) / 2 = 2.6
x = (-15 - 20.2) / 2 = -17.1
For x = 2.6:
y = -15 - x = -15 - 2.6 = -17.6
So, one possible pair of numbers is x = 2.6 and y = -17.6.
For x = -17.1:
y = -15 - x = -15 - (-17.1) = 2.1
So, another possible pair of numbers is x = -17.1 and y = 2.1.
Therefore, the two numbers that multiply to 56 and add to -15 are approximately -17.1 and 2.6, or vice versa.

Because angle TQR & angle TRU are complementary angles, meaning they add up to 90º.
So if TQR = 18, then:

Solve the pair of simultaneous equations and leave the answer as a fraction in
its lowest term. 2x − 3 = y, x+ y= 8
Answer:
x = 11/3 = 3 2/3
y = 13/3 = 4 1/3
Step-by-step explanation:
Here, we want to solve the system of equations simultaneously
x + y = 8
2x -3 = y
From the second equation, we have an equation for y
we can simply proceed to substitute this into the first equation
x + 2x - 3 = 8
3x - 3 = 8
3x = 8 + 3
3x = 11
x = 11/3
Recall;
y = 2x - 3
y = 2(11/3) - 3
y = 22/3 - 3
y = (22-3(3))/3
y = (22-9)/3 = 13/3

Answer:
30.96 m^2
Step-by-step explanation:
Side length of the square is also the diameter of the semicircle so:
r = 0.5 * 12 m = 6 m
Since you want the area of the shaded area, you have to subtract the area of both semi circles from the area of the square:
Square Area - Semi Circle Area - Semi Circle Area = Shaded Region Area
(12 m * 12 m) - (0.5 * 3.14 * 6^2 m) - (0.5 * 3.14 * 6^2 m)
= 144 - 56.52 - 56.52
= 30.96 m^2

M1 = mean (for the entire test) of the group that received the positive binary variable (i.e. the “1”).
M0 = mean (for the entire test) of the group that received the negative binary variable (i.e. the “0”).
Sn = standard deviation for the entire test.
p = Proportion of cases in the “0” group.
q = Proportion of cases in the “1” group.
Most people won’t work this formula by hand as most statistical software packages can calculate the coefficient for you.
1.) The graph of g(x) = ax? opens downward and is narrower than the graph of f(x) = x? Which of the following
could be the value of a?
a. 5
b. 0.5
C. -5
d. -0.5
Answer:
C. -5
Step-by-step explanation:
for g(x) =ax and f(x) = x, both are linear function. There is nothing to be upward or downward and both are lines nothing to compare its narrowness.
If g(x) = ax² vs f(x) = x²
Then a = -5 is the answer (-: downward and 5: vertical stretch)

A diver is 50 ft below sea level. Which integer correctly represents the situation?
Answer:
50 feet below sea level. First, look for keywords. The word “below” means you will need to use a negative integer. The answer is -50.
Step-by-step explanation:
hope this helps...
(─‿─)
Negative integers are used to represent values below zero, and in this context, "-50" represents a depth of 50 feet below the sea level.
In the context of sea level and vertical position, we often use positive and negative numbers to represent positions above or below a reference point, which is usually considered to be sea level.
When we say the diver is 50 feet below sea level, it means the diver is at a depth of 50 feet under the surface of the sea. In this case, we use negative numbers to represent positions below sea level.
So, if we consider sea level as the reference point (zero level), the number line extends in both positive and negative directions. Positive numbers represent positions above sea level, and negative numbers represent positions below sea level.
Since the diver is 50 feet below sea level, we represent this as -50. The negative sign indicates that the diver is below the reference point (sea level), and the absolute value of 50 represents the depth of 50 feet.
Therefore, the integer -50 correctly represents the situation of a diver being 50 feet below sea level.
