Answer:
12.5 miles per hour
Step-by-step explanation:
The speed is the distance divided by time.
3.75 miles/0.3 hours= 12.5 miles per hour
Answer:
12.5 miles per hour
Step-by-step explanation:
To answer this question you have to make sure that the hours (denominator) equals to 1. To do this, divide 3.75 by 0.3, thus making the 0.3 hours into 1 hour. This results in 12.5 miles per hour, the correct answer. Hope this helped!

Solve for x.
X^2-6x+10=2
Answer:
x = 2, 4
Step-by-step explanation:
Step 1: Write out quadratic
x² - 6x + 10 = 2
Step 2: Subtract 2 on both sides
x² - 6x + 8 = 0
Step 3: Factor
(x - 4)(x - 2) = 0
Step 4: Find roots
x - 4 = 0
x = 4
x - 2 = 0

- 3(4r - 8) = 36 - 2r
Answer:
r= -1.2
Step-by-step explanation:
first use distributive property
- 3(4r - 8) = 36 - 2r
-12r +24 = 36-2r
+2r. +2r
-10r +24= 36
-24. -24
-10r = 12
/-10. /-10
r= -1.2
Answer:
Step-by-step explanation:
Equation: -3(4r - 8) = 36 - 2r
Step 1:
-12r + 24 = 36 - 2r Multiply (4r - 8) by -3 using the Distributive Property.
Step 2:
-10r + 24 = 36 Add -12r and -2r by 2r.
Step 3:
-10r = 12 Subtract 24 and 36 by 24.
Step 4:
r = -12/10 Divide both sides by -10
Step 5:
r = -6/5 Simplify the fraction.
what is n to the -2 power times n to the 6 power
Answer:

Step-by-step explanation:
So we have:
[tex]n^{-2}\cdot n^6[/tex]
We can use the following property:
[tex]x^a\cdot x^b=x^{a+b}[/tex]
Thus, our expression is equivalent to:

Mr. Freeman has a square cornfield. Which of the following could be the
area of the cornfield if the sides are measured in whole numbers?
150 square acres
189 square acres
200 square acres
225 square acres
Step-by-step explanation:
Notice that 15 squared = (3 * 5)^2 = 9 * 25 = 225.
So the area of the cornfield can be 225 square acres.

What are the coordinates of Q'Q
Q is located at (0,6)
The translation rule is [tex](x,y) \to (x+7,y-5)[/tex] which says to add 7 to the x coordinate and subtract 5 from the y coordinate. Doing that to (0,6) moves it to (7,1) which is where point Q' is located.
In other words, if you shift point Q(0,6) seven units to the right and five units down, then it arrives at Q ' (7,1)
Answer: (7, 1)The coordinates of Q' are [tex]Q'(x,y) = (7, 1)[/tex].
Note - There are typing mistakes in the question. Correct statement is presented below:
Point Q' is the image of [tex]Q(0,6)[/tex] under the translation [tex](x,y) \to (x+7, y-5)[/tex]. What are the coordinates of Q'.
In this question we should use the point and the operation described in statement. Vectorially speaking, a translation is defined by the following operation:
[tex]P'(x,y) = P(x,y) + T(x,y)[/tex] (1)
Where:
[tex]P(x,y)[/tex] - Original point.[tex]P'(x,y)[/tex] - Translated point. [tex]T(x,y)[/tex] - Translation vector.If we know that [tex]Q(x,y) = (0,6)[/tex], then the coordinates of [tex]Q'(x,y)[/tex] are:

The coordinates of Q' are [tex]Q'(x,y) = (7, 1)[/tex].

Answer:

Step-by-step explanation:
Because they both of the same base, we can merge 2^5 and 2^3 into one term: 2^8 (2^(3+5))
4 is = 2^2 so we can change 4^4 to 2^8.
(2^(2*4)).
Thia means we now have 2^8/2^8 which is 1.

During a backgammon game, Jimmy rolled two dice on the board. Find the probability that the sum obtained was greater than 8 given that the number on one die was a 6
Answer:
2/3Step-by-step explanation:
This problem bothers on probability
Given that two dice are expected to give an outcome of sum greater than 8
But in the problem statement the first die is already settled since it is showing 6 already.
Now for the second die, the possible outcomes that will add up with the first die to produce a figure greater than 8 are (3,4,5,6)
The probability of obtaining either of these numbers is 4/6= 2/3
Having the first die settled, this means that the probability of obtaining a sum of 8 is 2/3

The Midpoint of UV is M(4, -6). Find V given U(7, -9)
Answer:
(1, -3)Step-by-step explanation:
Given the Midpoint of UV is M(4, -6) and U(7, -9), we are to find the other coordinate V. The formula for calculating the midpoint of two coordinates is expressed as shown;
M(X,Y) = (x1+x2/2, y1+y2/2)
X = x1+x2/2
Y = y1+y2/2
Given (X,Y) = ()4, -6)
U (x1, y1) = (7, -9)
To get x2 and y2, we will substitute the given values into th formula above;
4 = (7+x2)/2
cross multiply
4*2 = 7+x2
8 = 7+x2
x2 = 8-7
x2 = 1
Similarly for y2;
-6 = (-9+y2)/2
cross multiply
-6*2 = -9+y2
-12 = -9+y2
y2 = -12+9
y2 = -3
Hence the other coordinate V(x2, y2) is (1, -3)

Daniel growing corn in a square field. The length of one side is 100 yards he needs to purchase fertilizer for the corn field. Each bag covers 50 square yards .How many bags do he need?
Answer:
200 bags are needed
Step-by-step explanation:
First let us determine the area of the corn field:
Shape of cornfield = square
Area of a square = Length × Length
where: Length = 100 yards
∴ Area = 100 × 100 = 10,000 square yards
1 bag of fertilizer is needed to cover 50 square yards:
50 square yards = 1 bag of fertilizer
[tex]\therefore 1 \ square\ yard\ = \frac{1}{50}\ bag\\10,000\ square\ yards\ =\ \frac{1}{50} \times 10,000 = \frac{10l000}{50} \\ = 200 bags[/tex]
Hence, 200 bags are needed.
Answer:
200 bags are needed

Consider this expression.
(x + 9)(x - 2) - 9x - 6
What is equivalent?
Answer:
We can find an expression equivalent to the one given by expanding the expression given,
[tex](x + 9)(x - 2) - 9x - 6\\x^2-2x+9x-18-9x-6\\x^2-2x-24[/tex]
So [tex]x^2-2x-24[/tex] is a possible expression.
The required expression equivalent to (x + 9)(x - 2) - 9x - 6 is (x + 4)(x - 6).
Given that,
(x + 9)(x - 2) - 9x - 6, an equivalent expression is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
= (x + 9)(x - 2) - 9x - 6
= x² + 9x -2x -18 - 9x - 6
= x² - 2x - 24
= x² -6x + 4x - 24
= x (x - 6) + 4 (x - 6)
= (x + 4)(x - 6)
Thus, the required expression equivalent to (x + 9)(x - 2) - 9x - 6 is (x + 4)(x - 6).

Point E is on line segment DF. Given DE = 2x, EF = 2x – 6, and
DF = 3x + 5, determine the numerical length of EF.
Answer: EF =
Answer:
EF is 16.
Step-by-step explanation:
So we know that Point E is somewhere on Line DF. In other words, DE plus EF must equal DF. In an equation, this is:
[tex]DF=DE+EF[/tex]
We are given that DE is 2x, EF is 2x-6, and DF is 3x+5. So, substitute:
[tex](3x+5)=(2x)+(2x-6)[/tex]
Now, solve for x.
On the right, combine like terms:
[tex]3x+5=4x-6[/tex]
Subtract 4x from both sides:
[tex]-x+5=-6[/tex]
Subtract 5 from both sides:
[tex]-x=-11[/tex]
Divide both sides by -1:
[tex]x=11[/tex]
Now that we know x is 11, substitute this back into the equation for EF to find EF.
[tex]EF=2x-6[/tex]
Substitute 11 for x:
[tex]EF=2(11)-6[/tex]
Multiply:
[tex]EF=22-6[/tex]
Subtract:
[tex]EF=16[/tex]

a. $6,824.60
b. $6,355.10
c. $6,324.00
d. $6,220.00
Answer:
Option c.
Step-by-step explanation:
It is given that the piecewise function represents the Social Security taxes for 2009.
[tex]Tax=\begin{cases}0.062x & \text{ when } 0< x < 106,800 \\ \$6,621.60 & \text{ when } x > 106,800 \end{cases}[/tex]
We need to find Rachel's security tax if she earned $102,000 in 2009.
Since 102,000 lies in [tex]0<x<106,800[/tex], therefore
[tex]Tax=0.062x[/tex]
Put x=102000.
[tex]Tax=0.062(102000)[/tex]
[tex]Tax=6324[/tex]
So, the Social Security tax is $6324.
Therefore, the correct option is c.

How do I solve this problem?
Answer:
Step-by-step explanation:
The first 2 pieces of this function agree at pi/4, so we will set them equal to each other and sub in pi/4 for x to solve for k:
[tex]ksin(\frac{\pi}{4})+(\frac{\pi}{4})^2=\frac{\pi}{4}+2[/tex] and
[tex]k(\frac{\sqrt{2} }{2})+\frac{\pi^2}{16}=\frac{\pi}{4}+2[/tex] and we'll multiply everything by 16 to get rid of the fractions. Doing that gives us:
[tex]8k\sqrt{2}=4\pi+32-\pi^2[/tex] and
[tex]k=\frac{4\pi+32-\pi^2}{8\sqrt{2} }[/tex] so
k = 3.067
The next one is a bit tricky if you're not up on your natural log equations.
Again, we set these equal to each other because they meet at the value of e. We sub in e for x and solve for m:
[tex]x +2=mlne^x[/tex]
We'll sub in e for x. ln of e to the x power is equal to x, so
e + 2 = me and
[tex]m=\frac{e+2}{e}[/tex] so
m = 1.736
Hope that helps!
