Which of the following is equal to 11.4 9? A. (11 x 9) + (0.4 9) B. (11 + 9) + (0.4 +9) C. (11 x 9) * (0.4 * 9) D. (11 + 9) * (0.4 +9)
Answers
Answer
Option A is correct.
(11.4 × 9) = (11 × 9) + (0.4 × 9) = 102.6
Step-by-step Explanation
The best way to explain this is to examine the options one at a time to examine the one that is the most correct.
We want to know which of the options is equal to (11.4 × 9).
11.4 × 9 = 102.6
The options are
A. (11 × 9) + (0.4 × 9)
11 × 9 = 99
0.4 × 9 = 3.6
(11 × 9) + (0.4 × 9) = 99 + 3.6 = 102.6
B. (11 + 9) + (0.4 + 9)
11 + 9 = 20
0.4 + 9 = 9.4
(11 + 9) + (0.4 + 9) = 20 + 9.4 = 29.4
C. (11 × 9) × (0.4 × 9)
11 × 9 = 99
0.4 × 9 = 3.6
(11 × 9) × (0.4 × 9) = 99 × 3.6 = 356.4
D. (11 + 9) × (0.4 + 9)
11 + 9 = 20
0.4 + 9 = 3.6
(11 + 9) × (0.4 + 9) = 20 × 3.6 = 72
Since only option A gives the same answer as the expression in the question, option A is the only correct option.

Answers
We will have the following:
First, we know that 1 miles has 5280 feet, so 10 miles will have 52800 feet.
Then we will calculate how 15 feet would be represented:
[tex]x=\frac{2in\cdot15ft}{52800ft}\Rightarrow x=\frac{1}{1760}in\Rightarrow x\approx0.000568in[/tex]So, approximately 0.000568 inches would represent 15 feet.

A chemist is using 383 milliliters of a solution of acid and water.
If 17.3% of the solution is acid, how many milliliters of acid are there?

[tex]\begin{gathered} acid=17.3\%\: of\: 383\: mL \\ acid=\frac{17.3}{100}\times383 \\ acid=0.173\times383 \\ acid=6.3\: mL \end{gathered}[/tex]Therefore, the solution has 6.3 milliliters of acid.

Answers
In the isosceles trapezoid GJIH the length of HJ is 8.6
It is given that GJIH is the isosceles trapezoid
In an isosceles trapezoid the two non parallel sides are isosceles, that is the angle formed by them and the length of those two sides are equal.
The sides ,
GH = JI
GI and JH are the two diagonals of the trapezoid.
In any isosceles trapezium have equal opposite sides. Therefore diagonals of trapezium are equal.
The length of one of the diagonal GI is 8.6
So the length of another diagonal HJ is lenght of GI = 8.6

Plane a flies 4375 miles in the same amount of time
Answers
Given the following:
plane A flies 4375 miles
plane B flies 4550 miles
plane B is flying 35 mph more than plan A.
We are should find the amount of time it takes each plane to atravel their respective distances.
The time equation is:
4375 = 4550
x x + 35
Lets cross multipy
4375(x + 35) = x(4550)
4375x + 153125 = 4550x
153125 = 4550x - 4375x
153125 = 175x
175x = 153125
x = 153125/175
x = 875
x is the speed of plane A
Speed of plane B = 875 + 35 = 910
The amount of time plane A will use is = 4375/875 = 5
The amount of time plane B will use is = 4550/910 = 5
find the inverse of each given function f(x)=4x-12f^-1(x)=______x+______
Answers
The original function is f(x) = 4x - 12...
to find the inverse function, we need to solve it for x:
f(x) = 4x - 12
f(x) + 12 = 4x
(f(x) + 12)/ 4 = x
f(x)/4 + 3 = x
if we change now f^-1(x) for x and x for f^-1(x):
x/4 + 3 = f^-1(x)
f^-1(x) = x/4 + 3
f^-1(x) = (1/4)x + 3

Answers
Given the function:
[tex]f(x)=x^2+4x-12[/tex]Let's graph the function.
Let's find the following:
• (a). x-intercepts:
The x-intercepts are the points the function crosses the x-axis.
To find the x-intercepts substitute 0 for f(x) and solve for x.
[tex]\begin{gathered} 0=x^2+4x-12 \\ \\ x^2+4x-12=0 \end{gathered}[/tex]Factor the left side using AC method.
Find a pair of numbers whose sum is 4 and product is -12.
We have:
6 and -2
Hence, we have
[tex]\begin{gathered} (x+6)(x-2)=0 \\ \\ \end{gathered}[/tex]Equate the individual factors to zero and solve for x.
[tex]\begin{gathered} x+6=0 \\ Subtract\text{ 6 frm both sides:} \\ x+6-6=0-6 \\ x=-6 \\ \\ \\ x-2=0 \\ Add\text{ 2 to both sides:} \\ x-2+2=0+2 \\ x=2 \end{gathered}[/tex]Therefore, the x-intercepts are:
x = -6 and 2
In point form, the x-intercepts are:
(x, y) ==> (-6, 0) and (2, 0)
• (b). The y-intercept.
The y-intercept is the point the function crosses the y-axis.
Substitute 0 for x and solve f(0) to find the y-intercept:
[tex]\begin{gathered} f(0)=0^2+4(0)-12 \\ \\ f(0)=-12 \end{gathered}[/tex]Therefore, the y-intercept is:
y = -12
In point form, the y-intercept is:
(x, y) ==> (0, -12)
• (c). What is the maximum or minimum value?
Since the leading coefficient is positive the graph will have a minimum value.
To find the point where it is minimum, apply the formula:
[tex]x=-\frac{b}{2a}[/tex]Where:
b = 4
a = 1
Thus, we have:
[tex]\begin{gathered} x=-\frac{4}{2(1)} \\ \\ x=-\frac{4}{2} \\ \\ x=-2 \end{gathered}[/tex]To find the minimum values, substitute -2 for x and solve for f(-2):
[tex]\begin{gathered} f(-2)=(-2)^2+4(-2)-12 \\ \\ f(-2)=4-8-12 \\ \\ f(-2)=-16 \end{gathered}[/tex]Therefore, the minimum value is at:
y = -16
Using the point form, we have the minimum point:
(x, y) ==> (-2, -16).
• (d). Use the points to plot the graph.
We have the points:
(x, y) ==> (-6, 0), (2, 0), (0, -12), (-2, -16)
Plotting the graph using the points, we have:

Height: Suppose you are 5 feet 8 inches tall. Give your height in meters and centimeters.For example, "9'2" = 2.8 meters = 2 meters and 80 centimeters."You are meters andcentimeters.
Answers
Height is 5 feet 8 inches.
1 feet is 12 inches. So,
(5*12) + 8 = 68 inches
Now, let's convert to meters.
We know:
1 inch = 0.0254 meters
So, 68 inches would be:
68 * 0.0254 = 1.7272 meters
We would need to convert the fractional part (excess of 1, which is 0.7272) to cm.
We know:
1 m = 100 cm
So,
0.7272 m is:
0.7272 * 100 = 72.72 cm

The range of the given data set will be 15.
What is the range?When the sample maximum and minimum are subtracted, the range of a collection of data is the difference between the greatest and lowest values. It uses the same units as the data to express itself.Find the biggest observed value of a variable (the maximum) and subtract the smallest observed value to determine the range (the minimum).The range is the range of values, from lowest to highest. Example: The lowest value in 4, 6, 9, 3, and 7 is 3, while the highest value is 9. The range is therefore 9 - 3 = 6.So, the range of the given data:

Answers
Let it be:
• x: The smaller number.
,• x + 22: The larger number.
The product of both numbers is:
[tex]x(x+22)[/tex]Since the product of both numbers is -121, we can write:
[tex]x(x+22)=-121[/tex]The word 'is' is represented by the symbol =.
Therefore, the equation to solve the given word problem is:
[tex]x(x+22)=-121[/tex]Step 2To find the numbers, we solve the previous equation.
[tex]\begin{gathered} x(x+22)=-121 \\ \text{ Apply the distributive property on the left side} \\ x\cdot x+22\cdot x=-121 \\ x^2+22x=-121 \\ \text{ Add }121\text{ from both sides} \\ x^2+22x+121=-121+121 \\ x^2+22x+121=0 \end{gathered}[/tex]Now, we can factor the expression on the left side using the perfect square trinomial rule.
[tex]a^2+2ab+b^2=(a+b)^2[/tex]Then, we have:
[tex]\begin{gathered} x^2+22x+121=0 \\ x^2+2\cdot11\cdot x+11^2=0 \\ (x+11)^2=0 \\ \text{ Apply square root to both sides of the equation} \\ \sqrt[]{(x+11)^2}=\sqrt[]{0} \\ x+11=0 \\ \text{ Subtract 11 from both sides} \\ x+11-11=0-11 \\ x=-11 \end{gathered}[/tex]Finally, we find the another number.
[tex]\begin{gathered} x+22=-11+22 \\ x+22=11 \end{gathered}[/tex]Therefore, the numbers are -11 and 11.
