Answer:
75 inches
Step-by-step explanation:
First, the perimeter of a rectangle is 2(length)+2(width). The length and total of the perimeter was given to us, so the equation looks like 2(48)+2(w)=246
96+2w=246 (multiply and add where you can on both sides)
2w=150 (get all of the variables on one side and the numbers on the other)
w=75 (simplify to get your final answer)
width is 75 inches. [make sure to add the units!]

Answer:
∠ A ≈ 77.8°
Step-by-step explanation:
Using the Sine rule in Δ ABC
[tex]\frac{BC}{sinA}[/tex] = [tex]\frac{AB}{sinC}[/tex]
[tex]\frac{37}{sinA}[/tex] = [tex]\frac{29}{sin50}[/tex] ( cross- multiply )
29 × sinA = 37 × sin50° ( divide both sides by 29 )
sinA = [tex]\frac{37sin50}{29}[/tex] , then
A = [tex]sin^{-1}[/tex] ( [tex]\frac{37sin50}{29}[/tex] ) ≈ 77.8° ( to 1 dec. place )

Step-by-step explanation:
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.
In a class of 29 students, 20 have a brother and 8 have a sister. There are 3 students who do not have any siblings. What is the probability that a student chosen randomly from the class is an only child?
Answer: 1/4 = 0.25 = 25%
Step-by-step explanation:
Let x be the number of students having both brother and sister.
Brother only is 9-x
Sister only is 16-x
Brother only + sister only + both + neither = 28
(9-x) + (16-x) + x + 7 = 28
32 - x = 28
x = 4
The probability per the diagram is 4/16 = 1/4
Per definition of conditional probability:
prob( brother | sister) = prob ( brother AND sister) / prob ( sister)
= 4/16 = 1/4
1/4 = 0.25 = 25%

3/29

Answer:
9 1/3
Step-by-step explanation:
6 2/3 + 2 2/3 = ?
6 + 2 = 8
2/3 + 2/3 = 4/3 = 1 1/3
8 + 1 1/3 = 9 1/3
Sharon skated for 9 1/3 hours.

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.)

A right triangle undergoes a sequence of transformations to generate a new
triangle. Which of the following sequences of transformations would result in
the two triangles being similar but not congruent?
Answer:
Option a.
Step-by-step explanation:
Two figures are similar if they have the same shape, but maybe different sizes, so if we have a triangle, and we dilate/contract it with a scale factor K, the original triangle and the dilated/contracted one will be similar.
Two figures are congruent if they have the same shape and size. For example, transformations that do not change the size will make congruent figures, those transformations are reflections, rotations and translations.
Now we need to find a sequence of transformations that would result in the two triangles being similar but no congruent, then we need to find the sequence of transformations that has a dilation/contraction in it.
The only sequence that has a dilation is the first one:
a) Rotation 90° centered about the origin, followed by a dilation of scale factor 3 centered about the origin.
Then option a is the correct one.
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

Answer:
(B) Among registered voters, there was a steep increase in social media usage to follow political figures across all age groups and party
Step-by-step explanation:
From the chart of the question. It can be seen that at an average when comparing the year 2010 against the year 2014, there is an obvious or sharp increase in social media usage to follow political figures
There is also the issue of party affiliation which contributes to such an increase.
