Answer:
(c) The angles measure 90°.
Step-by-step explanation:
A (convex) quadrilateral with four equal-length sides must be a rhombus, so must have opposite sides parallel and diagonals that are perpendicular bisectors. In order for the rhombus to be a square, its angles must measure 90°.

Suppose that the relation S is defined as follows. S= {(4,9), (-9,4), (0, -9), (6, 6)} Give the domain and range of S. Write your answers using set notation.

range =
Answers
Given:
The relation S is:
[tex]S=\{(4,9),(-9,4),(0,-9),(6,6)\}[/tex]
To find:
The domain and range of S.
Solution:
If a relation is defined by the set of ordered pairs (x,y), then the domain is the set of x-values and range is the set of y-values.
Let R be a relation defined as [tex]R=\{(x,y):x\in R,y\in R\}[/tex], then [tex]Domain=\{x:x\in R\}[/tex] and [tex]Range=\{y:y\in R\}[/tex].
The given relation is:
[tex]S=\{(4,9),(-9,4),(0,-9),(6,6)\}[/tex]
Here, x-values are 4,-9,0,6 and the y-values are 9,4,-9,6.
So, the domain and range of the given relation S are
[tex]Domain=\{-9,0,4,6\}[/tex]
[tex]Range=\{-9,4,6,9\}[/tex]
Therefore, [tex]Domain=\{-9,0,4,6\}[/tex] and [tex]Range=\{-9,4,6,9\}[/tex].

The pair of figures to the right are similar. Compare the first figure to the second. Give the ratio of the perimeters and the ratio of the areas .
Answers
Given:
The pair of similar triangles.
Base of smaller triangle = 10 in
Base of larger triangle = 14 in
To find:
The ratio of the perimeters and the ratio of the areas.
Solution:
Ratio of perimeter of similar triangles is equal to the ratio of their corresponding sides.
[tex]\text{Ratio of perimeters}=\dfrac{10\ in.}{14\ in.}[/tex]
[tex]\text{Ratio of perimeters}=\dfrac{5}{7}[/tex]
[tex]\text{Ratio of perimeters}=5:7[/tex]
The ratio of area of similar triangles is equal to the ratio of squares of their corresponding sides.
[tex]\text{Ratio of areas}=\dfrac{(10)^2}{(14)^2}[/tex]
[tex]\text{Ratio of areas}=\dfrac{100}{196}[/tex]
[tex]\text{Ratio of areas}=\dfrac{25}{49}[/tex]
[tex]\text{Ratio of areas}=25:49[/tex]
Therefore, the ratio of the perimeters is 5:7 and the ratio of the areas 25:49.

Answers
Answer:
Well assuming you mean which will be the better option it would be the 60 ounce and 1.20 option. Since if you find the unit rate for that you’d only get 0.02 dollars for each ounce of soda. And for the 20 ounce one you’d get 0.05 dollars per ounce. The better option is the 60 ounces bottle for 1.20.

If 2 inches is about 5.08 centimeters, about how many inches is 32 centimeters? Round your answer to the nearest hundredth if necessary.
Answers
Answer:
12.60 inches
Step-by-step explanation:
Divide 5.08 by 2 to get 2.54. This means that for every 1 inch, there is 2.54 centimeter. Using this rule, we divide 32 by 2.54 to get 12.598 inches, or 12.60 if we round to the nearest hundredth.

Answers
9514 1404 393
Answer:
10. $16,000
11. 4%
12. 16.9%
Step-by-step explanation:
10. The amount of the loan plus interest is given by the formula ...
I = Prt
P = I/(rt) = $7840/(0.07×7) = $16,000
Richard initially deposited $16,000.
__
11. The total of principal plus interest is ...
A = P(1 +rt)
Solving for r gives ...
r = (A -P)/(Pt) = (528000 -240000)/(240000×30) = 0.04 = 4%
The percentage rate used was 4%.
__
12. The interest formula is ...
I = Prt
Solving for r gives ...
r = I/(Pt) = $845/($1000×5) . . . . . . 60 months = 5 years
r = 0.169 = 16.9%
To earn $845 in interest, you would need a rate of 16.9%.

A researcher tests the braking distances of several cars. The braking distance from 60 miles per hour to a complete stop on dry pavement is measured in feet. The braking distances of a sample of cars are normally distributed, with a mean of 129 feet and a standard deviation of 5.18 feet. What is the longest braking distance one of these cars could have and still be in the bottom 1%
Answers
Answer:
The longest braking distance one of these cars could have and still be in the bottom 1% is of 116.94 feet.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The braking distances of a sample of cars are normally distributed, with a mean of 129 feet and a standard deviation of 5.18 feet.
This means that [tex]\mu = 129, \sigma = 5.18[/tex]
What is the longest braking distance one of these cars could have and still be in the bottom 1%?
This is the 1st percentile, which is X when Z has a pvalue of 0.01, so X when Z = -2.327.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-2.327 = \frac{X - 129}{5.18}[/tex]
[tex]X - 129 = -2.327*5.18[/tex]
[tex]X = 116.94[/tex]
The longest braking distance one of these cars could have and still be in the bottom 1% is of 116.94 feet.
