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

The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis. The x-intercept is the x value when y = 0. Another way to reword that is when the graph crosses the x-axis.Step-by-step explanation:
x-int
According to the graph, it crosses the x-axis at 5. Therefore, our x-int is (5, 0)
y-int
According to the graph, it crosses the y-axis at 4. Therefore, our y-int is (0, 4)

the difference between two numbers is 48. the ratio of the two nukbers is 7:3. what are tge two numbers
The difference between the two numbers is 48. The ratio of the two numbers is 7 : 3. Hence, 84 and 36 are the two numbers.
Given :-
The difference between the two numbers is 48.
The ratio of the two numbers is 7 : 3.
To Find :-
The Two Numbers
Solution :-
Let the first number be 7x
And the second number be 3x
According to the Question,
⇒ 7x - 48= 3x
⇒ 7x-3x = 48
⇒ 4x = 48
⇒ x = 48/4
⇒ x = 12
1st number is= 7x = 84
2nd number= 3x = 36
Hence, 84 and 36 are the two number

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%

A line's y-intercept is 9, and its slope is 10. What is its equation in slope-intercept form?
Answer:
y=10x+9
Step-by-step explanation:
Slope intercept form is y=mx+b
m represents slope so 10 replaces the m
b represents the y-intercept (where the line crosses the y-axis) so 9 replaces the b
Is 0.000027 greater than 270?
Answer:
no because it is lower than 1 and 270 is higher
Answer:
No, because 0.000027 is a decimal. Any decimal with 0. *something* will be less than one. 27 is more than one. Thus, the statement is false.
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 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
This is approximately 25.612 when you use your calculator.

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.
