Step-by-step explanation:
i hope i didnt answer too late i see that ot says 7 min remaining but oh well
the answer
equation: (7x-13)+(x+29)+(3x + 5) = 180 (the reason why i put = to 180 is because every triangle adds up to 180 degrees)
first of all add the numbers: 29-13+5 = 21--- then add variables: 7x+3x+x= 11x
you get ur equation as: 11x + 21 = 180--- 180-21=11x---159=11x--- 159/11=14 9/20
x = 14 9/20 permiter = 88.15 + 43.45 + 48.35 = 179.95
really hope this helps :) good luck
What is an equation in slope-intercept form of the line that passes through (6, 10) and is parallel to the graph of y=1/3x−1?
Given:
The equation of line is
[tex]y=\dfrac{1}{3}x-1[/tex]
To find:
The equation of line in slope-intercept form parallel to given line and passes through (6,10).
Solution:
The slope intercept form of a line is
[tex]y=mx+b[/tex] ...(i)
where, m is slope and b is y-intercept.
The equation of given line is
[tex]y=\dfrac{1}{3}x-1[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=\dfrac{1}{3}[/tex]
Slope of given line is [tex]\dfrac{1}{3}[/tex].
We know that slope of parallel lines are same. So, the slope of required line is [tex]\dfrac{1}{3}[/tex].
Since slope of required line is [tex]\dfrac{1}{3}[/tex] and it passes through (6,10), therefore the equation of line is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-10=\dfrac{1}{3}(x-6)[/tex]
[tex]y-10=\dfrac{1}{3}(x)-\dfrac{1}{3}(6)[/tex]
[tex]y-10=\dfrac{1}{3}(x)-2[/tex]
Add 10 on both sides.
[tex]y-10+10=\dfrac{1}{3}(x)-2+10[/tex]
[tex]y=\dfrac{1}{3}(x)+8[/tex]
Therefore, the required equation of line is [tex]y=\dfrac{1}{3}(x)+8[/tex].
Musa and Akiola together invest $52,000 in a business and agree to share the profit in the ratio of their investment. Musa receives $5,000 and Akiola receives $8,000 as a profit at the end of the first year. How much did each invest?
Money invested by Musa and Akiola together in a buisness=$52,000
Profit earned by Musa =$5,000
Profit earned by Akiola=$8,000
Ratio of profit earned by Musa to the profit earned by Akiola:-
[tex] = 5000 : 8000[/tex]
Now, let us simplify the ratio of their profits:-
[tex] = 5000 : 8000[/tex]
[tex] = \frac{5000}{8000} [/tex]
[tex] = \frac{5000 \div 1000}{8000 \div 1000} [/tex]
[tex] = \frac{5}{8} [/tex]
[tex] = \bold{ 5 : 8}[/tex]
Thus, the ratio of profit earned by Musa to the profit earned by Akiola=5:8
It is given that :-The ratio of profit earned by Musa to the profit earned by Akiola=The ratio of money invested by Musa to the money invested by Akiola
Which means :-The ratio of money invested by Musa to the money invested by Akiola=5:8
Then :-Money invested by Musa :-
[tex] = \frac{5}{5 + 8} \: \: of \: \: 52000[/tex]
[tex] = \frac{5}{13} \: \: of \: \: 52000[/tex]
[tex] = \frac{5}{13} \times 52000[/tex]
[tex] = \frac{5 \times 52000}{13} [/tex]
[tex] = \frac{260000}{13} [/tex]
[tex] = \bold{\$ \: 20,000}[/tex]
Thus, the money invested by Musa =$20,000
Money invested by Akiola:-
[tex] = \frac{8}{5 + 8} \: \: of \: \: 52000[/tex]
[tex] = \frac{8}{13} \: \: of \: \: 52000[/tex]
[tex] = \frac{8}{13} \times 52000[/tex]
[tex] = \frac{8 \times 52000}{13} [/tex]
[tex] = \frac{416000}{13} [/tex]
[tex] = \bold{ \$ \: 32,000}[/tex]
Thus, the money invested by Akiola =$32,000
As the sum of their investments add up to form $52,000 we can conclude that we have found out the correct amount of money each of them invested in the business.
Therefore, the money invested by Musa in the buisness =$20,000 and the money invested by Akiola in the buisness=$32,000

Find the angle measures. Justify you responses.
Given: a//b, m<3= 63 degrees
Find: m<6, m<7
(The < is used as the angle sign)
Answer:
i think 89
Step-by-step explanation:
Answer:
m∠6 = 117º
m∠7 = 63º
Step-by-step explanation:
m∠3 = m∠7 = 63º(corresponding angles)
180º - m∠3 = m∠6 = 117º (same side interior angles are supplementary)
or
180º-m∠7 = m∠6 = 117º (linear pair)
4. Two savings accounts each start with a $200 principal and have an interest rate of 5%. One account earns simple interest and the other is compounded annually. Which account will earn more interest over 10 years? How much more?
Answer:
The compounded annually account will earn more interest over 10 years
Step-by-step explanation:
The rule of the simple interest is I = Prt, where
P is the original valuer is the rate in decimalt is the timeThe rule of the compounded interest is A = P[tex](1+\frac{r}{n})^{nt}[/tex], where
A is the new valueP is the original valuer is the rate in decimaln is the number of periodst is the timeThe interest I = A - P
∵ Each account start with $200
∴ P = 200
∵ They have an interest rate of 5%
∴ r = 5% = 5 ÷ 100 = 0.05
∵ One account earns simple interest and the other is compounded
annually
∴ n = 1 ⇒ compounded annually
∵ The time is 10 years
∴ t = 10
→ Substitute these values in the two rules above
∵ I = 200(0.05)(10)
∴ I = 100
∴ The simple interest = $100
∵ I = A - P
∵ A = 200[tex](1+\frac{0.05}{1})^{1(10)}[/tex]
∴ A = 325.7789254
∵ I = 325.7789254 - 200
∴ I = 125.7789254
∴ The compounded interest = $125.7789254
∵ The simple interest is $100
∵ The compounded interest is $125.7789254
∵ $125.7789254 > $100
∴ The compounded annually account will earn more interest
over 10 years

Interpret the correlation coefficient.
the data show a ___ ___ correlation.
Answer:
ŷ = -0.18363X + 19.71681
-0.9685
Step-by-step explanation:
Given the data:
Mileage, x: 22 14 18 30 8 24
Price, y: 16 17 17 14 18 15
Using the online regression calculator :
The regression equation obtained is :
ŷ = -0.18363X + 19.71681
Where ;
y = predicted variable
- 0.18363 = slope or gradient
X = predictor variable
19.71681 = intercept
The correlation Coefficient R = -0.9685
This signifies a strong negative relationship between the x and y variable.
The line of best fit has an equation of:
y = -0.1875x + 19.625
A linear equation is given by:
y = mx + b;
where y, x are variables, m is the slope of the line and b is the y intercept.
Let x represent the mileages (in thousands of miles) and y the selling prices(in thousands of dollars) of used automobiles.
Plotting the points using geogebra graphing calculator, the line of best fit has an equation of:
y = -0.1875x + 19.625
Therefore the slope is -0.1875 and the y intercept is 19.625

Keiko, Juan, and Tony have a total of $80 in their wallets. Keiko has $5 less than Tony. Juan has 3 times what Tony has. How much does each have?
Answer:
Keiko 12 + Juan 51 + Tony 17 = $80
Step-by-step explanation:
K + J + T = 80
K=T-5
J=3T
T=T
T-5 + 3T + T = 80
5T -5 = 80 --> 5T = 85 --> T = 17
now that u know T=17, substitute the value of T to find K and J
K=(17)-5 = $12
J=3(17) = $51
T= $17

In the morning, the temperature was 15∘F. During the day, the temperature fell 37 degrees. Which expression shows how to find the temperature at the end of the day?
Answer:
- 22°F
Step-by-step explanation:
Given that :
Morning temperature = 15°F
Change in temperature = fall by 37 degree
The temperature of the end of the day:
Morning temperature + (change in temperature)
Fall by 37° = decrease in temperature by 37° = - 37°
15°F + (-37°F)
15°F - 37°F
= - 22°F

what is an equation of the line that passes through the points (0,8) and (6,7)? Put your answer in fully reduced form.
Step-by-step explanation:
Hey there!
The given points are;(0,8) and (6,7).
Note: Remember to use two point formula for finding the eqaution which has two points.
Or
You can find Slope through the slope formula and then use one point formula to find eqaution.
Now, let's use here two point formula.
The formula is;
[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]
Now, keep all values.
[tex](y - 8) = \frac{7 - 8}{6 - 0} ( x - 0) [/tex]
Simplify it.
[tex](y - 8) = - \frac{1}{6} (x)[/tex]
[tex]y - 8 = - \frac{1}{6} x[/tex]
[tex]or \: \frac{1}{6} x + y - 8 = 0[/tex]
Therefore, the eqaution is; (1/6)X + y - 8 = 0.

If the graph of f(x) = x is shifted up 9 units, what would be the equation of the new graph?
A. g(x) = f(x) – 9
B. g(x)=f(x – 9)
c. g(x) = 9 - f(x)
D. g(x) = f(x) + 9
Answer:
b. g (x) = 9f (0)
Step-by-step explanation:
hope it help
==========================================================
Explanation:
Replace f(x) with y. This is valid because both represent outputs of a function. This means f(x) + 9 is the same as y+9, which means "move every point up 9 units".
For instance, the point (1,1) turns into (1,10) after moving it up 9 units. Here we added 9 to the y coordinate while keeping the x coordinate the same. You can write the translation rule as [tex](x,y) \to (x, y+9)[/tex]

Write the equation of the parabola in vertex form that has the following properties: passes through the point (2, 12) and has a vertex of (4,-4)
Answer:
f(x) = 4(x - 4)² - 4Step-by-step explanation:
f(x) = a(x - h)² + k - vertex form of the equation of the parabola with vertex (h, k)
so the equation of parabola with the vertex (4, -4) is
f(x) = a(x - 4)² - 4
passes through the point (2, 12) means if x=2 then f(x)=12
12 = a(2 - 4)² - 4
12 +4 = a(-2)² - 4 +4
16 = 4a
a = 4
Therefore the equation (in vertex form) of parabla is:
f(x) = 4(x - 4)² - 4
g(x)=−x+5, solve for x when g(x)=-2
