Explanation:
Thor: 30 laps
Shaq: 5/9 Thor's laps.
To find how many laps Shaq did, we have to multiply Thor's laps by 5/9:
[tex]30\times\frac{5}{9}=\frac{30\times5}{9}=\frac{150}{9}[/tex]And simplify the fraction:
[tex]\frac{150}{9}=\frac{50}{3}[/tex]It's an improper fraction. Written as a mixed number:
[tex]\frac{50}{3}=16\frac{2}{3}[/tex]Answer:
Shaq did 16 2/3 laps around the lake

The point P. = (x,1/3) lies on the unit circle shown below. What is the value of x insimplest form?
When a point (x,y) lies on a unit circle, the following equation holds true:
[tex]x^2+y^2=1[/tex]We are given
[tex]y=\frac{1}{3}[/tex]and need to find x.
Let's put it into the equation and figure out x. Shown below:
[tex]\begin{gathered} x^2+y^2=1 \\ x^2+(\frac{1}{3})^2=1 \\ x^2+\frac{1}{9}=1 \\ x^2=1-\frac{1}{9} \\ x^2=\frac{8}{9} \\ x=\sqrt[]{\frac{8}{9}} \\ x=\frac{\sqrt[]{8}}{\sqrt[]{9}} \\ x=\frac{\sqrt[]{8}}{3} \end{gathered}[/tex]We can simplify the square root of 8 by using the radical property:
[tex]\sqrt[]{a\cdot b}=\sqrt[]{a}\sqrt[]{b}[/tex]Thus, square root of 8 becomes:
[tex]\sqrt[]{8}=\sqrt[]{4\cdot2}=\sqrt[]{4}\sqrt[]{2}=2\sqrt[]{2}[/tex]Thus, the simplest form of x is:
[tex]x=\frac{2\sqrt[]{2}}{3}[/tex]How many tablespoons of blue paint should Elena mix with 6 cups of white paint and blue paint? How many batches would this make?
According to the given graph, 2 cups of white paint are in the same ratio as 6 tablespoons of blue paint.
So, if she has 6 cups of white paint, we just have to multiply the number of tablespoons by 3.
[tex]6\times3=18[/tex]So, Elena needs 18 tablespoons of blue paint.Additionally, this would make three batches because the given ratio is being multiplied by 3.Which interval notation represents a function with a domain of all real numbers greater than -3 and less than 6?A.) -2
The domain is the values of x, and if we want x to fit the inequalities they gave us, we have that
[tex]-3\leq x<6[/tex]if p || , m<7 = 131°, and m<16 = 88°, find the measure of the missing angle m<13 = ?
Answer:
[tex]m\angle13=92^o[/tex]Explanation:
First, we match the angles
9 = 11
10 = 12
16 = 14
15 = 13
Therefore, if we find angle 15, we find an angle 13.
Angle 15 is supplementary to angle 16; therefore,
[tex]\angle16+\angle15=180^o[/tex]Since
[tex]\angle16=88^o[/tex]Therefore,
[tex]88^o+\angle15=180^o[/tex]subtracting 88 from both sides
[tex]\angle15=180^o-88^o[/tex][tex]\angle15=92^o[/tex]which is our answer!
6. Use common denominators for these fractions. Arrange them from smallest to largest.
Given the fractions:
[tex]\frac{9}{16},\frac{3}{8},\frac{1}{4},\frac{5}{8}[/tex]We will arrange them from the smallest to the greatest using the common denominators
So, the common denominator for the fractions will be = 16
[tex]\begin{gathered} \frac{9}{16}=\frac{9}{16} \\ \\ \frac{3}{8}=\frac{2\cdot3}{2\cdot8}=\frac{6}{16} \\ \\ \frac{1}{4}=\frac{4\cdot1}{4\cdot4}=\frac{4}{16} \\ \\ \frac{5}{8}=\frac{2\cdot5}{2\cdot8}=\frac{10}{16} \end{gathered}[/tex]So, the answer will be the arrange will be:
[tex]\begin{gathered} \frac{4}{16},\frac{6}{16},\frac{9}{16},\frac{10}{16} \\ \\ \frac{1}{4},\frac{3}{8},\frac{9}{16},\frac{5}{8} \end{gathered}[/tex]
Mars is about 142 million miles from the sun. The earth is about 93,000,000 miles from the sun. How much farther from the sun is Mars than the earth? Express the answer in scientific notation State the letter of the correct answer. A.) 235x10 B.) 2.35x107 C) 4.9x10 D.) 49x107
D)
1) Let's visualize it to better understand this
2) Let's pick the distance between Mars and the Sun, and subtract it by the distance (Earth-Sun):
[tex]142,000,000-93,000,000=49,000,000=49\cdot10^6\text{ or 4.9 }\cdot10^7[/tex]3) So Mars is 4.9 x 10^7 miles farther from the sun than the Earth.
Solve for Time Principle $2,000Interest $480Rate 8%
ANSWER:
t = 3
STEP-BY-STEP EXPLANATION:
Given:
Principle (P) = 2000
Interest (I) = 480
Rate (r) = 8% = 0.08
The simple interest formula is the following:
[tex]I=P\cdot r\cdot t[/tex]We substitute each value and solve for t, like this:
[tex]\begin{gathered} 480=2000\cdot 0.08\cdot \:t \\ \\ t=\frac{480}{2000\cdot0.08}=\frac{480}{160} \\ \\ t=3 \end{gathered}[/tex]Therefore, the time would be 3 periods (it depends on the interest rate if it is annual, monthly, etc.)
Graph the line 3x - 5y = 18
Given:
3x - 5y = 18
To graph this line, rewrite the equation in slope-intercept form:
y = mx + b
Where m is the slope and b is the y-intercept.
Subtract 3x from both sides:
3x - 3x - 5y = -3x + 18
-5y = -3x + 18
Divide all terms by -5:
[tex]\begin{gathered} \frac{-5y}{-5}=\frac{-3x}{-5}+\frac{18}{-5} \\ \\ y=\frac{3}{5}x-\frac{18}{5} \end{gathered}[/tex]Thus, the slope intercept form of the equation is:
[tex]y=\frac{3}{5}x-\frac{18}{5}[/tex]Any line can be graphed using two or more points.
Let's determine two points on the line.
Input 6 for x and solve for y:
[tex]\begin{gathered} y=\frac{3}{5}\ast6-\frac{18}{5} \\ \\ y=\frac{18}{5}-\frac{18}{5} \\ \\ y=0 \end{gathered}[/tex]Also, the y-intercept is:
[tex](0,-\frac{18}{5})[/tex]convert the fraction to decimal:
[tex]-\frac{18}{5}=-3.6[/tex]Thus, we have the points:
[tex]\begin{gathered} (0,-3.6) \\ (6,\text{ 0)} \end{gathered}[/tex]x y

Select all that apply. What value(s) for x make(s) the equation true?-8y - 2 = -8y - 2
According to the given data we have the following equation:
-8y - 2 = -8y - 2
In order to calculate the value(s) for x make(s) the equation true we would have to calculate variable y as follows:
We would substitute the y with the values 0, -15, 37, 343
So, if we substitute for 0
-8(0)-2=-8(0)-2
0-2=0-2
-2=-2
value for x=0 applies.
if we substitute for -15
-8(-15)-2=-8(-15)-2
120-2=120-2
118=118
if we substitute for 37
-8(37)-2 +8(37)+2=0
-296-2 +296+2=0
if we substitute for 343
-8(343) -2 +8(343)-2=0

A piece of wire 32 cm long is cut into two pieces, each to be bent to make a square. The length of a side of one square is to be 4 cm longer than the length of a side of the other How should the wire be cut?The length of the shorter piece of wire is :
Let P1 represent the perimeter of the larger square and let P2 represent the perimeter of the smaller square. Since the piece of wire is 32 cm long and both squares are made of this wire, we have the following:
[tex]P_1+P_2=32[/tex]Now let x be the length of the side of the smaller square. Since the larger square has sides 4cm longer than the length of the side of the other square, we have the following:
[tex]\begin{gathered} P_1=4(x+4) \\ P_2=4x \end{gathered}[/tex]using these expressions on the first equation and solving for x, we get:
[tex]\begin{gathered} 4(x+4)+4x=32 \\ \Rightarrow4x+16+4x=32 \\ \Rightarrow8x=32-16=16 \\ \Rightarrow x=\frac{16}{8}=2 \\ x=2 \end{gathered}[/tex]we have that x = 2. Then, the length of the shorter piece of wire will be the perimeter of the smaller square, therefore, the length of the shorter piece of wire is P2 = 4(2) = 8 cm

1.
The location of w and t on the number line arenot exact so you will need to approximate .
In the first point w, it is between -4 and - 3 but closer than -4 compared to -3.Additionally, the point w is located at a position greater than -3.5 .It will be okay to approximate point w at -3.6.
w= -3.6
In the second point t, it is located between 0 and 1 but closer to 0 than 1. Additionally, t is less than 0.5 because it is located at a position less than 0.5, hence it is approximately at : t = 0.4
w= -3.6 and t = 0.4 -------approximated actual values
The two real numbers for w and t will be :
w= - 4 and t = 0 ---------approximated real numbers.
NB;
w= -3.7 and t= 0.3 is also a correct approximate because the difference of +/- 0.1 can be allowed for this case.

Use the Leading Coefficient Test to determine the end behavior of the polynomial function. f((x) = (x + 1)(x + 4)(x + 5)^5
Answer:
The graph falls to the left and rises to the right.
Explanation:
Given f(x) defined below:
[tex]f\mleft(x)=(x+1)(x+4)(x+5)^5\mright?[/tex]We are to determine the end behavior of the polynomial using the Leading Coefficient Test.
When using the Leading coefficient test, the following rule applies:
• When the ,degree is odd, and the ,leading coefficient is positive,, the graph falls to the left and rises to the right.
,• When the ,degree is odd, and the ,leading coefficient is negative,, the graph rises to the left and falls to the right.
,• When the ,degree is even, and the ,leading coefficient is positive,, the graph rises to the left and right.
,• When the ,degree is even, and the ,leading coefficient is negative,, the graph falls to the left and right.
Back to our function, f(x):
[tex]\begin{gathered} f(x)=(x+1)(x+4)(x+5)^5 \\ \text{Degree}=7\text{ (Odd)} \\ \text{Leading Coefficient = 1 (Positive)} \end{gathered}[/tex]From the first rule above, we can conclude that the graph falls to the left and rises to the right.
A graph of f(x) is attached which confirms this end behavior.
