Explanation:
The tenths decimal place is right after the decimal point
7 is in the tenths place
The digit just to the right of 7 is 4
Since the 4 is not 5 or larger, this means we erase everything after the 7 and go with 3.7
If we had something like 3.76, then the 7 bumps up to 8 to get 3.8
The length of the rectangle is 5 more than twice the width. If the perimeter is 10 times that of the width, what is the width, length, and perimeter of the rectangle?
Width of the rectangle is 2.5, Length is 10 and perimeter is 25
Given
Length of rectangle is 5 greater than double of width
let us say width = w
According to the question length L = 5 + 2w
Perimeter is 10 times the width
P= 10w
we know that perimeter of a rectangle is 2(L+W)
Substituting the values in the formula we get
10w = 2(5+2w + w)
10w = 10 + 6w
w= 2.5
From this length L = 5+2(2.5)
L = 10
Perimeter P = 10W
P= 10(2.5)
P= 25
Hence the length is 10, width is 2.5 and perimeter is 25

Answer:
14 units²=============================
Given Vertices A(-5,2), B(-3,2), C(-2,-5), D(-4,-5)To find The area of ABCDSolutionWe can observe that:
1. AB and CD are horizontal segments, since both endpoints have same y-coordinates:
A and B have y = 2, C and D have y = - 52. AB and CD are of same length:
AB = - 3 - (-5) = 2,CD = - 2 - (-4) = 2.It means the ABCD is a parallelogram, since two opposite sides are parallel and of same length.
The area of parallelogram is:
A = bh, where b- base length, h - heightWe know the length of the base, it is found above, 2 units.
The height is the difference of y- coordinates:

Use I = PTR to solve
(time is in years)
I=$252
R=7% find T.
P=$900
The time period in years T = 4 years
The simple interest amount = $252
The rate of interest per year as percentage = 7%
The principal amount = $900
The simple interest I = PTR
Where I is the interest amount
P is the principal Amount
T is the time period involved in years
R is the rate of interest per year as a percent
Substitute the values in the equation
252 = 900 × T × (7 / 100)
252 = 900 × T × 0.07
252 = 63 × T
Move the 63 to other side
T = 252 / 63
T = 4 years
Hence, the time period in years T = 4 years

The function f(x) = 210-60x represents a second trip, where f(x) is the number of miles
the car is from its destination after x hours. Which trip takes less time? Explain.
Answer:
the trip represented by f(x) takes less time
Step-by-step explanation:
Given a table of time and distance to go, and a function f(x) = 210-60x representing the same for a different trip, you want to know which trip takes less time.
TableThe table has values ...
(time in hours, remaining distance in miles) = (1, 150), (2, 100), (3, 50)
This shows you the remaining distance decreases by 50 miles for every hour added to the travel time. That means the remaining 50 miles will be reduced to zero after 4 hours.
The trip represented by the table takes 4 hours.
EquationThe function f(x) = 210-60x will have a value of zero when ...
0 = 210 -60x
0 = 3.5 -x . . . . . . divide by 60
x = 3.5 . . . . . . . . add x
The trip represented by the function f(x) takes 3.5 hours.
The second trip takes less time.
ou have three jars of gumballs. the first jar has 100 white gumballs and 25 green, the second jar has 50 white and 150 blue, and the third jar contains 500 white and 10 red. if you randomly draw one gumball from each jar, what is the probability for at least one white gumball?
The probability for at least one white gumball is 0.196
Consider the following:
First jar:100 whites, 25 green
Total=100+25
=125 gumball
P(White)=100/125=0.8
Second jar:50 whites, 150 blue
Total=50+150
=200 gumballs
P(White)=50/200=0.25
Third jar:500 whites, 10 red
Total=500+10
=510
P(White)=500/500=0.98
Now, probability for at least one white is
=P(white in jar 1)*P(white in jar 2)*P(white in jar 3)
=0.8*0.25*0.98

Ivan has been given a list of 5 bands and asked to place a vote. His vote must have the names of his favorite, second favorite, and third favorite bands from the list. How many different votes are possible?
Using combinations, there are a total of 20 distinct voting combinations.
We now have five bands. We'll refer to them as A, B, C, D, and E.
John will choose two bands from the available five if he is required to vote for his favorite and second-favorite.
We must pair bands and discover every possible combination in order to determine the TOTAL number of different possibilities.
The results/totals are as follows:
AB, AC, AD, AE
BA, BC, BD, BE
CA, CB, CD, CE
DA, DB, DC, DE
EA, EB, EC, ED
Thus, there are a total of 20 distinct voting combinations.
Since you already know that each of the five initial bands (A, B, C, D, and E) will result in a multiple of four, you may accomplish it more simply without listing by taking the five bands.

Write an equation in standard form for the line that passes through the given points
(3,0) and (0, -2)
Equation of a line in the standard form that passes through the points (3, 0) and (0, -2) will be [y = (2/3)x - 2].
As per the question statement, a straight line passes through the points (3, 0) and (0, -2).
We are required to determine the equation of the above mentioned line in it's standard form.
To solve this question, we need to know the formula to write the standard equation of a line passing through two points (x₁, y₁) and (x₂, y₂) which goes as [tex][(y-y_{1})=\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}(x-x_{1})][/tex].
Here, let (x₁, y₁) be (3, 0) and (x₂, y₂) be (0, -2).
Therefore, equation of our concerned line passing through the two points (3, 0) and (0, -2), by substituting [(x₁, y₁) = (3, 0)] and [(x₂, y₂) = (0, -2)] in the above mentioned formula, will be [(y - 0) = {(-2 - 0)/0₂ - 3)}(x - 3)]
Or, [y = {(-2)/(-3)}(x -3)]
Or, [y = (2/3)(x - 3)]
Or, [y = (2/3)x - 2]

Answer: 9 units to the right and 5 units down
Step-by-step explanation:
1) Measure the length.
You can find that you can match point C with point W. Next find how much it goes to the right and left.
Right from (C->W): 9 squares
Down from (C->W): 5
2) Fill in the blank
9 units to the right and 5 units down
Answer:
ΔABC ≅ ΔNKW because when ΔABC is translated 9 units right and 5 units down, it results in the other triangle.
Step-by-step explanation:
The triangles are congruent as the measures of their corresponding sides and angles are the same.
To determine the translation of ΔABC to ΔNKW, find the change in the x and y values from one of the points of ΔABC to its corresponding point of ΔNKW.
Point C = (0, 0)Point W = (9, -5)Therefore:
ΔABC ≅ ΔNKW because when ΔABC is translated 9 units right and 5 units down, it results in the other triangle.

A piggy bank contains $2.65 in nickles and dimes. if the number of nickles is 7 less than three times the number of dimes. how many of each are there
In this question, we have been given a piggy bank contains 2.65$ in nickels and dimes. Then There are 29 nickels and 12 dimes in the piggy bank.
We need to find the number of nickels and dimes if the number of nickels is 7 less than three times the number of dimes.
Let x be the number of nickels and y be the number of dimes.
We know that, 1 dollar = 20 nickels
and 1 dollar = 10 dimes
So, we get an equation
0.05x + 0.1y = 2.65 ...........(1)
Also the number of nickels is 7 less than three times the number of dimes.
x = 3y - 7 .................(2)
Substitute above value of x in equation (1)
0.05(3y - 7) + (0.1)y = 2.65
0.15y - 0.35 + 0.1y = 2.65
0.25y = 2.65 + 0.35
0.25 y = 3
y = 12
Substitute above value of y in equation (2)
x = 3(12) - 7
x = 29
Therefore, there are 29 nickels and 12 dimes in the piggy bank.
