Answer: Lena walks 63 miles in 10 days.
Step-by-step explanation:
To find out how many miles Lena walks in 10 days, you need to add up all the distances she walks each day.
From the information provided, it seems that the distances walked each day are:
23 miles, 11 miles, 10 miles, 19 miles and the remaining days is not given.
So, to find the total miles Lena walks in 10 days, you would add up the distances walked each day:
23 + 11 + 10 + 19 = 63 miles
So, Lena walks 63 miles in 10 days.
The total miles in 10 days will bed 14 miles. The closest option is OD, which is 19 miles.
How to calculate the distance covered?To find the total distance Lena walks in 10 days, we need to add up all the distances on the line plot:
Starting from day 1, we can count the distances and add them up:
On day 1, Lena walks 1 mile
On day 2, Lena walks 2 miles
On day 3, Lena walks 1 mile
On day 4, Lena walks 1 mile
On day 5, Lena walks 2 miles
On day 6, Lena walks 1 mile
On day 7, Lena walks 2 miles
On day 8, Lena walks 1 mile
On day 9, Lena walks 1 mile
On day 10, Lena walks 2 miles
Adding up all these distances, we get:
1 + 2 + 1 + 1 + 2 + 1 + 2 + 1 + 1 + 2 = 14
Therefore, Lena walks a total of 14 miles in 10 days.
Thus, the closest option is OD, which is 19 miles.

Find the measure of the given angle
Answer:
A= 110 degrees AND B= 140 degrees.
Y= 112 degrees and X= 157 degrees.
Step-by-step explanation:
Triangle XYZ is an isocoles triangle, because it has two congruent sides. 70 degrees is a measurement of an angle opposite of one of those congruent sides, so angle YXZ is also 70 degrees. By the triangle angle sum theorem, we can say that the measurement of angle YZX is 40 degrees. So, for the first triangle, by the linear pairs theorem, we can find the two missing angles.
A= 110 degrees AND B=140 degrees.
For the triangle on the right, we can use the triangle angle sum theorem to say that angle BDC is 68 degrees. Then, we can say that by the by the linear pairs theorem that angle ADE is 112 degrees. From there, we need to look at the 23 degree measurement on the lower right triangle. We can see that the angle steadily rises on that line and then we can take 180-23 by the linear pairs theorem to conclude than angle BEA is 157 degrees. This can be confirmed by looking at the two innermost angles in the top right triangle. If you take 180-23-112, you will get 45. If you add 45 to 112, you will get 157.
Y= 112 degrees and X= 157 degrees.

Find the sum of the following geometric series:
8 + 1.6 + 0.32 + 0.064 + ...
Answer:
10
Step-by-step explanation:
The given series is a geometric series with the first term a = 8, and the common ratio r = 1/5. To find the sum of the series, we can use the formula for the sum of an infinite geometric series:
S = a / (1 - r)
So, in this case, the sum of the series is:
S = 8 / (1 - 1/5) = 8 / (4/5) = 8 * (5/4) = 40/4 = 10.
Therefore, the sum of the series is 10.
Answer:
10
Step-by-step explanation:
A geometric series is the sum of the terms of a geometric sequence.
[tex]\boxed{\begin{minipage}{5.5 cm}\underline{Sum of an infinite geometric series}\\\\$S_{\infty}=\dfrac{a}{1-r}$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\ \phantom{ww}$\bullet$ $r$ is the common ratio.\\\end{minipage}}[/tex]
Given geometric series:
8 + 1.6 + 0.32 + 0.064 + ...The ellipsis means to "continue in this pattern". Therefore, find the sum to infinity of the given geometric series.
From inspection of the sequence, the first term is 8:
[tex]\implies a=8[/tex]
To find the common ratio, divide consecutive terms:
[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{1.6}{8}=0.2[/tex]
Substitute the found values of a and r into the geometric series formula:
[tex]\implies S_{\infty}=\dfrac{8}{1-0.2}=\dfrac{8}{0.8}=10[/tex]
Therefore, the sum of the given geometric series is 10.

Step-by-step explanation:
If you used good technique, you would expect the range of measurements to be small. Good technique would include using a measuring instrument that is calibrated correctly, measuring in the same position and at the same time of day, and being consistent in how you position your body during the measurement. All of these factors would help to reduce the amount of measurement error and therefore lead to a smaller range of measurements.

What is interest and its types(Simple and compound interest)?
Interest is the cost of borrowing money, where the borrower pays a fee to the lender for the loan. The interest, typically expressed as a percentage, can be either simple or compounded. Simple interest is based on the principal amount of a loan or deposit. In contrast, compound interest is based on the principal amount and the interest that accumulates on it in every period. Simple interest is calculated only on the principal amount of a loan or deposit, so it is easier to determine than compound interest.
The formula for these are
Simple Interest= P×r×n
where:
P=Principal amount
r=Annual interest rate
n=Term of loan, in years
Compound Interest=P×(1+r)^t−P
where:
P=Principal amount
r=Annual interest rate
t=Number of years interest is applied
Here,
Interest rate will be risk percentage + LIBOR
i.e.4.8%
Hence, the interest can be found by using formula for simple interest
Therefore,
SI=P*r*t
=$450000*0.048*0.25 (Time is 3 month or 0.25 years.)

Find the equation of the line that passes through (1,3) and is perpendicular to y=2x+3. Leave your answer in the form ax+by=c Where a, b and c are integers.
Answer:
2y+x=7
Step-by-step explanation:
The equation of a line is in the form:
[tex]y = mx + c[/tex]
where m is the gradient and c is the y-intercept.
In the equation y=2x+3 the gradient is 2, so to find the perpendicular gradient, it is the negative reciprocal, or in other words, flip the number upside down and make it negative:
[tex]2 = \frac{2}{1} [/tex]
[tex] \frac{2}{1} \: flipped \: upside \: down = \frac{1}{2} [/tex]
[tex] make \: \frac{1}{2} \: negative = - \frac{1}{2} [/tex]
So the gradient for the point (1, 3) is -1/2
Using y=mx+c to find c (the y-intercept) where y=1, m=-1/2, x=1, substitute these values in:
[tex]y = mx + c[/tex]
[tex]3 = - \frac{1}{2} (1) + c[/tex]
[tex]3 = - \frac{1}{2} + c[/tex]
[tex]3 + \frac{1}{2} = c[/tex]
[tex]c = \frac{7}{2} [/tex]
So the equation is:
[tex]y = - \frac{1}{2} x + \frac{7}{2} [/tex]
We need to write this in the form ax+by=c, so multiply everything by 2 to get rid of the fractions on the right:
[tex]2y = - x + 7[/tex]
Bring x to the left side by adding it:
[tex]2y + x = 7[/tex]
This is now in the form ax+by=c

Step-by-step explanation:
Did this also and used mathaway
You decide to put $5,000 in a savings account to save for a $6,000 down payment on a new car. If the account has an interest rate of 7% per year and is compounded monthly, how long does it take until you have $6,000 without depositing any additional funds?
The time it takes until the deposit amounts to $6,000 is 2.6 years
Compound interest: Calculating timeFrom the question, we are to calculate how long it takes until the deposit amounts to $6000
From the compound interest formula, we have that
A = P(1 + r/n)^nt
Where A is the amount
P is the principal
r is the interest rate
n is the number of times compounded per year
and t is the time.
From the given information,
P = $5,000
r = 7%= 0.07
n = 12
t = ?
A = $6,000
Putting the parameters into the formula
A = P(1 + r/n)^nt
6000 = 5000(1 + 0.07/12)^(12×t)
6000/5000 = (1 + 0.0058333)^12t
1.2 = (1.0058333)^12t
Take log1.0058333 of both sides
31.346375 = 12t
31.346375/12 = t
t = 2.6 years
Hence, the time it takes is 2.6 years

the ratio of height and length of a store room is 5:4 and the ratio of height and breadth is 2:3. find the area of the floor of the store room if the total area of the four walls of the store room is 2760m^2
Answer: The area of the floor of the store room is 1080 m^2
Step-by-step explanation:
We can begin by using the information provided about the ratios of the dimensions of the store room to set up a system of equations.
Let's call the height of the store room h, the length l, and the breadth b.
From the first ratio given, we know that:
h/l = 5/4
From the second ratio given, we know that:
h/b = 2/3
We can also use the information about the total area of the four walls to set up another equation.
The total area of the four walls is the sum of the area of the top and bottom walls (length x height) and the area of the two side walls (breadth x height).
So we have:
2lh + 2bh = 2760
We can now use the first two equations to solve for one of the variables in terms of the other two.
We can cross-multiply and simplify the first equation:
l = (4/5)h
We can cross-multiply and simplify the second equation:
b = (3/2)h
We can now substitute these expressions for l and b into the equation for the total area of the four walls:
2(4/5)h^2 + 2(3/2)h^2 = 2760
Solving for h, we get:
h = 30
Now that we know the value of h, we can use the equations l = (4/5)h and b = (3/2)h to find the values of l and b.
l = (4/5)h = (4/5)(30) = 24
b = (3/2)h = (3/2)(30) = 45
Now we have all the information we need to find the area of the floor, which is the product of the length and breadth of the store room
Area of floor = lb = 2445 = 1080 m^2
Explanation: By using the information about the ratios of the dimensions of the store room and the total area of the four walls, we set up a system of equations and used algebra to solve for the height, length and breadth of the store room. With this information, we were able to find the area of the floor of the store room.

What is the domain and range of the function ?
The domain of the function is (-∞, 1), (1, ∞).
the correct option is (C)
What is domain and Range?The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
Given:
As, we know the domain are the input values in the function.
So, From the graph the domain starts from -∞ to reach 1 then there is change in slope.
Next the domain starts from to ∞.
Now, range is the output value as (-4, 1).
Hence, the domain is (-∞, 1), (1, ∞).
