Answer:
Step-by-step explanation:
A triangle's angles have to equal to 180 degrees , so option B is not a triangle because it equals to 175
Answer:
A. Triangle? Yes. How do I know? Triangles add up to 180 degrees, and the angles measures add up to 180.
B. Triangle? No. How do I know? The angle measures only add up to 175 degrees, so it can’t be a triangle.
C. Triangle? Yes. How do I know? A triangle = 180 degrees and the angle measures add up to 180.
Slope of (7, -2) and (2, -6)
Answer:
[tex]\boxed{\sf{m=\frac{4}{5}}}[/tex]
Step-by-step explanation:
In order to solve this problem, we will use the slope.
Slope:
[tex]\sf\dfrac{Y_2-Y_1}{x_2-x_1}=\dfrac{rise}{run}[/tex]
y2=(-6)
y1=(-2)
x2=2
x1=7
Solve the problem by rewriting it down.
[tex]\sf{\dfrac{(-6)-(-2)}{2-7} }=\dfrac{(-6)+2}{2-7}=\boxed{\dfrac{4}{5} }[/tex]
m=4/5
Therefore, the slope is 4/5.
I hope this helps! Feel free to correct me if I am wrong.
PLEASE HELP Solve for x. Round to the nearest tenth, if necessary.
ANSWER:
2.1
EXPLANATION:
angle = 38
opposite side = 1.3
hypotenuse = X
Based on this we must use sine (opposite / hypotenuse)
sin (38⁰) = 1.3 / x
x = 1.3 / sin (38⁰) [use calculator]
x = 2.1
In order to join a dancing club there is a $30 startup fee and a $4 monthly fee. Write an equation in slope intercept form that models this situation.
Answer:
y = 4x + 30
Step-by-step explanation:
The startup fee is $30 and must be paid before you begin. This means that 30 in the y-intercept. You pay $30 at 0 months. Then you have to pay $4 every month after that. This means that 4 is the slope. So, after x months, the total amount you have paid, y, is
y = 4x + 30

2/4 + 3/9 in Modeling Fractions?
Answer: 13/12
Step-by-step explanation:
Reduce the fraction 3/9 to the lowest terms by extracting and canceling out 3.
The least common multiple of 4 and 3 is 12. Convert 3/4 and 1/3 to fractions with denominator 12.
Since 9/12 and 4/12 have the same denominator, add them by adding their numerators.
Add 9 and 4 to get 13.

Which ratio best defines relative frequency? Number of nonfavorable outcomes:Number of possible outcomes Number of possible outcomes:Number of nonfavorable outcomes Total number of times an experiment is performed:Number of times an event occurs Number of times an event occurs:Total number of times an experiment is performed.
The ratio which best defines relative frequency is, number of times an event occurs:Total number of times an experiment is performed.
What is relative frequency?Relative frequency of a event is the measure of something happens relative to the total outcomes of that event.
The relative frequency can be given as,
[tex]f_r=\dfrac{f}{n}[/tex]
Here, (f) is the frequency of the number of times data occurred in an event and (n) is the total number of outcomes.
The relative frequency can also be defined as, it is the ratio of subgroup frequency to the total frequency of any event.
Now, the ratio has to be find out which best defines relative frequency. Lets check options,
Number of non-favorable outcomes:Number of possible outcomes-Here, the non-favorable outcomes is asked but for the relative frequency the favorable outcomes is considered. Number of possible outcomes:Number of non-favorable outcomes-The number of total outcomes is considered for a relative frequency. Total number of times an experiment is performed:Number of times an event occurs-This ratio is inverse as the ratio of relative frequency.Number of times an event occurs:Total number of times an experiment is performed-This is the correct option, as it justify the definition of the relative frequency.Hence, the ratio which best defines relative frequency is, number of times an event occurs:Total number of times an experiment is performed.

The quotient of the start fraction 7 superscript 7 negative 6 over 7 squared end fractions is,
[tex]\dfrac{1}{7^8}[/tex]
What is the quotient?Quotient is the resultant number which is obtained by dividing a number with another. Let a number a is divided by number b. Then the quotient of these two number will be,
[tex]q=\dfrac{a}{b}[/tex]
Here, (a, b) are the real numbers.
The number given in the problem is,
[tex]\dfrac{7^{-6}}{7^2}[/tex]
Let the quotient of these number is n. Therefore,
[tex]n=\dfrac{7^{-6}}{7^2}\\[/tex]
Now if the power of numerator is negative, then it can be written in denominator with positive power of the same number. Therefore, the above equation written as,
[tex]n=\dfrac{1}{7^2\times7^{6}}\\n=\dfrac{1}{7^{2+6}}\\n=\dfrac{1}{7^8}[/tex]

Element X is a radioactive isotope such that every 22 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 1200 grams, how long would it be until the mass of the sample reached 800 grams, to the nearest tenth of a year?
Step-by-step explanation:
s1 = 1200 g
s2 = 1200×2^(-1/22)
s3 = 1200×2^(-2/22)
...
s23 (22 years later) = 1200×2^-22/22 ≈ 1200×2^-1 = 1200/2
sn = 1200×2^(-(n-1)/22)
what is the n, so that the result is 800 g ?
800 = 1200×2^(-(n-1)/22)
800/1200 = 2^(-(n-1)/22)
2/3 = 2^(-(n-1)/22)
log2(2/3) = -(n-1)/22
22×log2(2/3) = -(n - 1) = -n + 1
n = -22×log2(2/3) + 1 = 13.86917502...
since we stared counting with n=1 for the starting quantity, the number of years is truly 1 less than n (s2 is after 1 year, s3 after 2 years ...).
so, we know for n = 13.86917502..., that in fact
12.86917502... ≈ 12.9 years have passed until the mass of the sample reached 800g.
