The following statement is true about the triangles (d) D = 77 and E = 79
What is dilation?Dilation involves enlarging or reducing the side length of a shape to create another shape by a constant scale factor,
Where the scale factor does not equal to one.
How to determine the true statements in the figure?From the attached image, we understand that there are two shapes
The shapes are triangles
One triangle is the scaled factor of the other
So, the triangles are similar shapes
As a general rule, the following are the properties of a scaled copy of another figure
If the scale factor is greater than 1, the side lengths would be greater than the original figureIf the scale factor is less than 1, the side lengths would be less than the original figureThe corresponding angles of both figures are the sameUsing the above as a guide, we have the following
D =B = 77 -- by corresponding angles
Also, we have
E = A = 180 - 77 - 24 -- by corresponding angles
E = A = 79
Hence, the true statement is (d) D = 77 and E = 79

Select all that apply.A divide 2/5 by 1/4 to find the unit rate per hour B The average speed will be less than 1 mile per hour because the group travels less than a fourth of a mile in1/4 of an hour C The group traveled at an average speed of 1 3/5 miles per hour.D The average speed will be greater than 1 mile per hour because the group travels more than a fourth of a mile in1/4 of an hour .E The group traveled at an average speed of 2 1/4 of a miles per hour.
Answers
The distance traveled, d = 2/5 miles = 0.4 miles.
The time taken to travel 0.4miles is given as, t = 1/4 hr = 0.25 hr.
Thus, the average speed, s = distance traveled divided by time taken.
i.e.
[tex]\begin{gathered} \text{average speed = }\frac{distance\text{ traveled}}{\text{time taken}}\text{ = }\frac{0.4}{0.25}\text{ } \\ \text{average sp}eed\text{ = 1.6 miles/hr} \end{gathered}[/tex]we can now go through the options and see the correct answers:
option A is correct because unit rate per hour is the same thing as average speed
option B is wrong because average speed is greater than 1mile/hr from our calculation above
option C is wrong because 13/5 gives us 2.6 miles/hr
option D is correct because the average speed is indeed greater than 1
option E is wrong because average speed is 1.6 miles/hr not 2 1/4 miles/hr

A package of 5 pairs of insulated gloves costs $28.955. What is the unit price of the pairs of gloves ?
Answers
If a package of 5 pairs of insulated gloves costs $28.955,then the unit price of the pairs of gloves is $5.791
A package of 5 pairs of insulated gloves costs $28.955
The price of 5 pairs of insulated gloves = $28.955
Here we have to use the unitary method
The price of 1 pair of insulated gloves = The price of 5 pairs of insulated gloves / 5
Substitute the values in the equation and divide it
The price of 1 pair of insulated gloves = 28.955/5
= $5.791

Victor received an 8-year subsidized student loan of $24,000 at an annual interest rate of 4.55%. If victor qualifies for an income-adjusted repayment plan of $500 per month, how long (in months) will it take him to repay the loan?
Answers
Time taken by Victor to repay the subsidized student loan of $24,000 at an annual interest rate of 4.55% is equal to 59 months.
As given in the question,
Principal = $24000 (given)
Rate of interest = 4.55% (given)
Time duration of subsidized loan = 8 years (given)
Repayment (equated monthly instalment) rate = $500 per month
To find: time for Victor to repay loan
We know that Principal + Simple Interest = Amount
Let t be the expected time duration for repayment of the subsidized student loan for Victor
24000+[tex]\frac{(24000).(4.55).t}{100}[/tex] = 500x12t (Simple Interest = Principal x Rate x Time)/100
=> 24000 + 1092t = 6000t
=> 4908t = 24000
=> t = 4.89 years ≈ 59 months
Therefore, it will take 59 months for Victor to repay the subsidized student loan of $24,000 at an annual interest rate of 4.55%.

Suppose you have a $60000 loan with an annual percentage rate of 8% for 25 years? Requires monthly payment?
Answers
The required monthly payment is $ 180,000
How to calculate SI?Simple interest is the cost of borrowing money that does not take compounding into consideration. In other words, just the principal is affected by simple interest. Simple interest is calculated by multiplying the principal by the time, interest rate, and time period. "Simple Interest = Principal x Interest Rate x Time" is the written formula.
Given: Principal= $60000
Rate= 8% and time= 25 years
To calculate the monthly payment use the formula:
Simple interest=PRT/100
= 60,000×8×25/100
=120,000
And total amount accrued will be $180,000.

Step-by-step explanation:
You want to divide 8x^3-18x^2+24x+3 by 4x-1 using polynomial long division.
Polynomial long divisionPolynomial long division is similar to numerical long division, except that the quotient term is always the ratio of the leading dividend term to the leading divisor term.
As with numerical long division, the dividend at each step is reduced by the product of the quotient term and the divisor.
When the dividend is of lower degree than the divisor, the division is finished. That dividend is the remainder.
The attachment shows the division in detail. Your result is ...
q(x) +r(x)/b(x) = (2x^2-4x+5) +(8)/(4x-1)

What are median in math?
The middle number is obtained by sorting all the data points and choosing the center one (or if there are two middle numbers, taking the mean of those two numbers). Example: Because the number 4 is in the middle when the numbers are ordered (1, 4, 7), it is the median of 4, 1, and 7.First we need to sort the data from Smallest to largest data value which is allready sorted
n = 40
Five number summary can be calculated as
Minimum = 25
Q1 can be calculated as
Lower Half of 40 values is 20, so median of 20 values will give us 25th percentile so Median = (20+1)/2 = 10.5th here 10th value is 57 and 11th value is 59 so Q1 = (57+59)/2 = 58
Median = (n+1)/2 = (40+1)/2 = 20.5th value and 20th and 21st value is 72 so median = (72+72)/2 = 72
Upper 20 values after median will provide us Q3 or 75th percentile which can be calculated as 20+(20+1)/2 = 30.5th value so 30th value is 81 and 31st value is also 81. So Q3 = (81+81)/2 = 81
Max = 98
So five number summary is 25, 58,72,81,98

We need to distribute 7/8 of a gallon into cups of 1/16 of a gallon. It means that to know the number of cups, we need to divide 7/8 into 1/16.
So, let's remember how to make a division between two fractions:
[tex]\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot d}{b\cdot c}[/tex]Then, the division of 7/8 into 1/16 is equal to:
