Answer:
53.8 mi^2
Step-by-step explanation:
First we need to determine the radius of the crater. The circumfence formula is C = 2(pi)r, and here C = 26 miles. Thus,
26 mi = 2(pi)r, so that
26 mi
r = ------------ = 4.13 miles
2pi
Then the area of the crater is A = (pi)r^2, or:
A = 3.14(4.13 mi)^2 = 53.8 mi^2

State if the triangles in each pair are similar. If so, state how you know they are similar
A.They are similar by the AA rule
B.They are not similar
C.They are similar by the SSS rule
Answer: C. They are similar by the SSS rule
Step-by-step explanation:
There are three ways to prove triangle similar
AA similar theorem--Two corresponding angles in two triangles are the congruentSAS similar theorem--Two corresponding pairs of sides of two triangles are proportional, and the angle in between two sides are congruentSSS similar theorem--All corresponding sides of two triangles are proportional--------------------------------------------------------------------------------
Here, we see in the figures, the side lengths are given, and there are no angles. So, supposedly, we are going to use SSS similar theorem.

MN corresponds to UV
ML corresponds to UT
LN corresponds to TV
MN/UV=24/8=3
ML/UT=33/11=3
LN/TV=42/14=3
∴MN/UV=ML/UT=LN/TV
∴They are similar

What's (7.3 x 10^-1) (.004) in standard notation
Answer:
.73(.004) or .00292
Step-by-step explanation:
First, you should look at the equation: (7.3x10^-1). This means you would have to move the decimal to the left one time. So, the equation would be .73(.004).
If you wanted to find the answer to this equation, you would get .00292.
Standard notation: (.73)(.004).
Answer:
2.92 x 10⁻³Step-by-step explanation:
(7.3 x 10⁻¹) (0.004) = (7.3 x 10⁻¹)(4 x 10⁻³) =(7.3*4) x 10⁻¹⁻³ =29.2 x 10⁻⁴ = 2.92 x 10⁻³classify the polynomial −8a2x2+15

Determine if the two triangles are congruent. If they are, state
the condition.
Answer:
HL
Step-by-step explanation:
Since we have two pairs of congruent sides with the included angle, one pair of which are the hypotenuses, then the triangles are congruent by HL.
Answer:
HL
Step-by-step explanation:
They are both Right triangles (a given set of triangles are congruent if the corresponding lengths of their hypotenuse and one leg are equal.)

The resale value of a bike decreases by 14% per year. A new bike is valued at $350. Approximate the resale value after 4 years to the nearest dollar.
Answer: $191.45
Step-by-step explanation:
This question requires the price of a bike in future so you can use the future value formula to calculate it:
Future value = Amount * (1 + rate)^ no. of periods
= 350 * (1 - 14%)⁴
= 350 * 0.54700816
= $191.45
The rate is subtracted from 1 instead of being added to represent that the value is decreasing not increasing.

Step-by-step explanation:
M varies directly as n, and m=14 when n=7 a) Write an equation that relates m and n b) find m when n=16 c) find n when m=30
Answer:a)m =K n
b)m = 32
c)n=15
Step-by-step explanation:
M varies directly as n can be expressed mathematically as
m ∝ n
Introducing the constant of proportionality, K, we have that
m =K n
Now when m=14 and n=7, K becomes
14=K X 7
K=14/7 = 2
b) find m when n=16
m =K n
m = 2 x 16=32
c) find n when m=30
m =K n
30=2 x n
n=30/2 =15
Expression is formed using numbers, variables, and mathematical operations. The value of m, when the value of n is 16 is 32.
What is Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
As we know that the value of m is directly varying with n, therefore, we can write the relationship as,
[tex]m \propto n[/tex]
Now, in order to remove the proportionality, we will add a constant,
[tex]m = kn[/tex]
As the value of m and n is given as 14 and 7, substitute the values in order to get the value of the constant k,
[tex]m = kn\\14 = k(7)\\\dfrac{14}{7} = k\\k=2[/tex]
We know the value of the constant k is 2, therefore, the equation can be written as,
[tex]m=2n[/tex]
Substitute the value of n as 16, to get the value of m,
[tex]m=2n\\m=2(16)\\m=32[/tex]
Hence, the value of m, when the value of n is 16 is 32.

Why is the median better to represent the data of a stem and leaf plot? I NEED THE ANSWER NOW PLSSSS
Answer:
The median value is better because it is not affected by the skewness of the data
Step-by-step explanation:
The median is better in representing the data of a stem and leaf plot because the median value is not affected so much by outliers and skewness of the data. for example: for a downward skewed stem and leaf plot the value of the median is greater than the mean value
Hence the median value is a better representation of the central tendency
A store clerk put out packages of chocolate chip and oatmeal cookies on a shelf. The ratio of the number of packages of oatmeal cookies to total cookies on the shelf was 3 to 10.
Which number could be the number of packages of chocolate chip cookies the clerk put out on the shelf?
a 9
b 6
c 20
d 14
Answer:
D) 14
Step-by-step explanation:
If the ratio of oatmeal to total cookies is 3:10 and chocolate chip is the only other type of cookie, that means there’s 7 choco chip for every 10 total cookies. Assuming the clerk put the cookies out in packages or something of 10, the answer would be D since it is the only answer that is a multiple of 7
