Answer:
1/33Step-by-step explanation:
Typically you would want to solve this equation by dividing both sides by 3 but we need to find an equivalent equation that gives the same answer. 3 divided by 3 is the same as 3 times 1/3. Thus;
3x * 1/3 = 9 * 1/3
x = 3
Best of Luck!
Answer:
3
Step-by-step explanation:
3x = 9

An athlete's target heart rate, in beats per minute, is $80\%$ of the theoretical maximum heart rate. The maximum heart rate is found by subtracting the athlete's age, in years, from 220. To the nearest whole number, what is the target heart rate of an athlete who is 26 years old
Answers
Answer:
155
Step-by-step explanation:
Since the question states that;
Maximum heart rate= 220 - athletes age
If athletes age = 26 years
Maximum heart rate= 220 - 26 = 194
Again;
athlete's target heart rate= 80% × Maximum heart rate
Athlete's target heart rate= 0.8 × 194= 155
Point G and point H are the same distance form point F. Which coordinates could be the location of point H?
Answers
Answer:
[tex]H = (5,1)[/tex]
Step-by-step explanation:
The attachment is not clear. However, the points of G and F are:
[tex]F = (3, 2)[/tex]
[tex]G = (4, 4)[/tex]
And the options are:
[tex]A.\ (1, 2) \\ B. (4, 2)\\ C. (5, 1) \\ D. (2, 5)[/tex]
Required
Determine the coordinates of H
This question will be solved using distance formula, D
[tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Since F is equidistant of G and H, the formula can be represented as:
[tex]D = \sqrt{(x_2 - x)^2 + (y_2 - y)^2}[/tex] and
[tex]D = \sqrt{(x_1 - x)^2 + (y_1 - y)^2}[/tex]
Where:
[tex](x_1,y_1) = (4,4)[/tex]
[tex](x,y) = (3,2)[/tex]
[tex]H = (x_2,y_2)[/tex]
Substitute values for x , y , x2 and y2 in [tex]D = \sqrt{(x_2 - x)^2 + (y_2 - y)^2}[/tex]
[tex]D = \sqrt{(x_2 - 3)^2 + (y_2 - 2)^2}[/tex]
Square both sides:
[tex]D^2 = (x_2 - 3)^2 + (y_2 - 2)^2[/tex]
Substitute values for x , y , x1 and y1 in [tex]D = \sqrt{(x_1 - x)^2 + (y_1 - y)^2}[/tex]
[tex]D = \sqrt{(4 - 3)^2 + (4 - 2)^2}[/tex]
Square both sides:
[tex]D^2 = (4 - 3)^2 + (4 - 2)^2[/tex]
[tex]D^2 = (1)^2 + (2)^2[/tex]
[tex]D^2 = 1 + 4[/tex]
[tex]D^2 = 5[/tex]
Substitute 5 for D^2 in [tex]D^2 = (x_2 - 3)^2 + (y_2 - 2)^2[/tex]
[tex]5 = (x_2 - 3)^2 + (y_2 - 2)^2[/tex]
From the list of given options, the values of x and y that satisfy the above condition is: (5,1)
This is shown below
[tex]5 = (5-3)^2 + (1-2)^2[/tex]
[tex]5 = (2)^2 + (-1)^2[/tex]
[tex]5 = 4 + 1[/tex]
[tex]5 = 5[/tex]
Other options do not satisfy this condition. Hence, the coordinates of H is:
[tex]H = (5,1)[/tex]

The letters in the word SANTA CLAUS are printed on identical index cards with one letter per card. The ten cards are then placed in a hat, and one card is randomly chosen (without looking) from the hat. The chance process we are interested in is what letter is on the selected card.
Answers
The missing part:
Make a model of probability showing the set of outcome and the probability value of each outcome.
Answer:
Step-by-step explanation:
From the given information:
a) From the word SANTA CLAUS, outcomes are all distinct letters.
This implies that the outcomes are S, A, N, T, C, L, U, S
For S, N, T, C, L, U, S letters, each of them is repeated once.
Thus, their respective probability = [tex]\dfrac{1}{10}[/tex]
A is repeated thrice, so probability for A = [tex]\dfrac{3}{10 }[/tex]
Using the probability distribution table; we have the following.
outcome S A N T C L U S
probability [tex]\dfrac{1}{10}[/tex] [tex]\dfrac{3}{10 }[/tex] [tex]\dfrac{1}{10}[/tex] [tex]\dfrac{1}{10}[/tex] [tex]\dfrac{1}{10}[/tex] [tex]\dfrac{1}{10}[/tex] [tex]\dfrac{1}{10}[/tex] [tex]\dfrac{1}{10}[/tex]

Prove that log(3) 7 is an irrational number
Answers
Answer:
Proof below
Step-by-step explanation:
Irrational and Rational Numbers
We need to use the basic property of logarithms:
[tex]log_b\ a=x\ \ \Rightarrow b^x=a[/tex]
We are given:
[tex]log_3\ 7[/tex]
And we will prove it's an irrational number, i.e., it's not a rational number.
Recall a rational number can always be expressed as a fraction a/b, where a and b are integer numbers. Thus, if the expression was a rational number, then:
[tex]\displaystyle log_3\ 7=\frac{a}{b}[/tex]
Applying the property:
[tex]\displaystyle 3^{\frac{a}{b}}=7[/tex]
Raising to the power of b:
[tex]3^a=7^b[/tex]
It's not possible to find two integers a and b that satisfy the condition above. That contradiction comes from the assumption that [tex]log_3\ 7[/tex] is rational, thus, it's proven [tex]log_3\ 7[/tex] is irrational.

*****HELP ASAP WILL MARK BRAINLIEST****** Ignore if you don't know!!!! Geometry problem: Point D is the incenter of triangleABC, if DE=x^2 and DF= 20-8x, find each of the following
Answers
Answer:
x = 2
DG = 4
Step-by-step explanation:
The thing to know about the incenter of a triangle, is that the segments to each side are equidistant. In other words, they are identical lengths.
This means that ED = FD = GD.
Which means:
DE = DF
x^2 = 20 - 8x
So we need to solve for X. I would solve this using factoring:
Subtract 20 from both sides.
x^2−20=−8x
Add 8x to both sides.
x^2−20+8x=0
Rearrange the polynomial to put it in standard form. Place the terms in order from highest to lowest power.
x^2+8x−20=0
Factor the left hand side by grouping. First, the left hand side needs to be rewritten as x^2+ax+bx−20. To find a and b, set up a system to be solved.
a+b=8 ab=1(−20)=−20
Since ab is negative, a and b have the opposite signs. Since a+b is positive, the positive number has greater absolute value than the negative. List all such integer pairs that give product −20.
(−1,20) (−2,10) (−4,5)
Calculate the sum for each pair.
−1+20=19
−2+10=8
−4+5=1
The solution is the pair that gives sum 8.
a=−2 b=10
Rewrite x^2+8x−20 as (x^2−2x)+(10x−20).
(x^2−2x)+(10x−20)
Factor out x in the first and 10 in the second group.
x(x−2)+10(x−2)
Factor out common term x−2 by using distributive property.
(x−2)(x+10)
To find equation solutions, solve x−2=0 and x+10=0.
x = 2
x = −10
In this case, X is equal to 2 as the solution -10 doesn't make much sense given the context of the problem.
To find DG we just need to plug the solution back into one of the equations and solve:
20 - 8x
20 - 8(2)
20 - 16 = 4
DG = 4

x=2

kristen and brett found three different deals on the same smart tv they want to figure out which deal is better before tax
1.Original Price: $320
Discount: 15% off
2.Original Price: $349.99
Discount: 75% off
3. Original Price: $360
New Price: $280
Answers
Answer:
Option 2 would be the better deal, as long as they would only pay $ 87.37 for the smart TV.
Step-by-step explanation:
To determine which deal is better before taxes, the aforementioned discounts must be made at the original prices and their results compared, through the following calculations:
1)
320 - (320 x 15/100) = X
320 - 48 = X
272 = X
2)
349.49 - (349.49 x 75/100) = X
349.49 - 262.11 = X
87.37 = X
3)
280 = X
Therefore, as can be seen, option 2 would be the better deal, as long as they would only pay $ 87.37 for the smart TV.
