Answer:
x=60
Step-by-step explanation:
Answer: The equation 60 + x= 3x -70 could be set up to solve for x.
Step-by-step explanation:
The two remote interior angles sums will equal to the exterior angle .
Meaning that angle 60 plus angle x has to equal to angle 3x -70.
60 + x= 3x -70 Now solve for x by adding 70 to both sides
+70 +70
130 + x = 3x Now subtract x from both sides
-x -x
130 = 2x Divide both sides by
x = 65

Diane flipped a coin 600 times and it landed heads up 240 times. What is the relative frequency of the coin landing heads up based on the results of this experiment?
4%
6%
40%
60%
Step-by-step explanation:
The relative frequency of the coin landing heads up is 0.4 or 40%.
Step-by-step explanation:
We are given that,
Total number of times coin is tossed = 600
Number of times heads comes = 240
Since, 'relative frequency' is the fraction of number of times an event occurs and the total number of events.
Thus, the relative frequency that heads comes = \frac{240}{600}
600
240
i.e. Relative frequency that heads comes = 0.4 or 40%
Thus, the relative frequency of the coin landing heads up is 0.4 or 40%.
Answer: 40%

Find the hypothesis for side a 16 side b 20
I think you mean to say "hypotenuse". If so, then use the pythagorean theorem to get the following
a^2 + b^2 = c^2
16^2 + 20^2 = c^2
256 + 400 = c^2
656 = c^2
c^2 = 656
c = sqrt(656)
c = sqrt(16*41)
c = sqrt(16)*sqrt(41)
c = 4*sqrt(41)
The hypotenuse is exactly 4*sqrt(41) units long

Triangle GHJ with vertices G(-2,4), H(3,6), and J(3,-2) is dilated by a factor of centered at the origin. What are the coordinates of G' after the dilation? 63,4) (2,4) . 3) O 12 2 3 3 3 (3,-4)
Answer:
The answer would most likely be the second one because that one makes the most sense here.
Step-by-step explanation:
When a triangle is dilated, the size of the triangle changes.
The coordinate of G' after dilation is: (a) [tex]\mathbf{(-\frac 23,\frac 43)}[/tex]
The vertices are given as:
[tex]\mathbf{G = (-2,4)}[/tex]
[tex]\mathbf{H = (3,6)}[/tex]
[tex]\mathbf{J = (3,-2)}[/tex]
The scale factor (k) is given as:
[tex]\mathbf{k =\frac 13}[/tex]
So, the image of G is calculated as:
[tex]\mathbf{G' = k \times G}[/tex]
This gives:
[tex]\mathbf{G' = \frac 13 \times (-2,4)}[/tex]
[tex]\mathbf{G' = (-\frac 23,\frac 43)}[/tex]
Hence, the coordinate of G' after dilation is: (a) [tex]\mathbf{(-\frac 23,\frac 43)}[/tex]

f(n) = 4(3)n − 1; f(5) = 324
Answer:
answer is C f(n) = 4(3)n; f(5) = 972
Step-by-step explanation:

The graph is an illustration of an exponential function
The true statement is (d) [tex]\mathbf{f(n) = 4(3)^{n-1}}[/tex], [tex]\mathbf{f(5) = 324}[/tex]
An exponential function is represented as:
[tex]y = ab^{x-1}[/tex]
From the graph, we have the following points
[tex](x_1,y_1) = (1,4)[/tex]
[tex](x_2,y_2) = (2,12)[/tex]
So, we have:
[tex]y = ab^{x-1}[/tex] --------- [tex](x_1,y_1) = (1,4)[/tex]
[tex]4 = ab^{1-1}[/tex]
[tex]4 =ab^0[/tex]
[tex]4 =a \times 1[/tex]
[tex]4 =a[/tex]
[tex]a = 4[/tex]
[tex]y = ab^{x-1}[/tex] --------- [tex](x_2,y_2) = (2,12)[/tex]
[tex]12 = ab^{2-1[/tex]
[tex]12 = ab[/tex]
Substitute [tex]a = 4[/tex]
[tex]12 = 4b[/tex]
Divide both sides by 4
[tex]3 = b[/tex]
[tex]b =3[/tex]
Recall that:
[tex]y = ab^{x-1}[/tex]
So, we have::
[tex]y = 4(3)^{x-1}[/tex]
Express as a function of n
[tex]\mathbf{f(n) = 4(3)^{n-1}}[/tex]
Substitute 5 for n, to calculate the 5th term
[tex]\mathbf{f(5) = 4(3)^{5-1}}[/tex]
[tex]\mathbf{f(5) = 4(3)^4}[/tex]
[tex]\mathbf{f(5) = 324}[/tex]
Hence, option (d) is correct

Mrs. Dobbs rides a taxi that charges a flat rate of $6.75 plus $3.20 per mile. The taxi charges Lupita $40.03 in total for her trip.
Subtract the flat rate from the total, then divide by price per mile for total miles:
40.03 - 6.75 = 33.28
33.28/3.20 = 10.4 miles.
Lupita drove 10.4 Miles for her trip.
Explanation:
40.03 - 6.75 = 33.28 dollars left
33.28 ÷ 3.20 = 10.4 Miles
Find out how long it takes a $ investment to double if it is invested at compounded . Round to the nearest tenth of a year. Use the formula . A. years B. years C. years D. years
Answer:
(A) 8.8 years
Step-by-step explanation:
Given that the principal amount = $ 3100
Rate of compound interest = 8% compounded semiannually.
The given formula is
[tex]A=P\left(1+\frac{r}{n}\right)^{nt}[/tex]
Where A is the final amount, P is the principal amount, r is the rate of compound interest, t is the time and n is the number of times per year the interest is compounded.
From the given condition,
P=$3100
r= 8%=0.08 compounded semiannually
n=2
A=2 x 3100=$ 6200.
Put all these in the given formula to get the required time, we have
[tex]6200=3100\left(1+\frac{0.08}{2}\right)^{2t}[/tex]
[tex]\Rightarrow \left(1+0.04\right)^{2t}=6200/3100[/tex]
[tex]\Rightarrow 1.04^{2t}=2\\\\\Rightarrow 2t\log_{10}(1.04)=\log_{10}(2)\\ \\\Rightarrow 2t =\frac{\log_{10}(2)}{\log_{10}(1.04)}\\\\\Rightarrow 2t =17.673\\\\\Rightarrow t = 17.673/2=8.8365\\[/tex]
On rounding to the nearest tenth of a year, t=8.8 years.
So, the invested amount will be double in 8.8 years.
Hence, option (A) is correct.
