Answer:
\(10:02:24\ \text{pm}\)
Step-by-step explanation:
d = Distance to travel = 880 miles
s = Average speed of the car = 65 mph
Time taken to cover the distance is
\(t=\dfrac{d}{s}\\\Rightarrow t=\dfrac{880}{65}\\\Rightarrow t=\dfrac{176}{13}\ \text{h}=13.54\ \text{hours}\)
Time the car stopped
\(3\times 10+60=90\ \text{minutes}=1.5\ \text{hours}\)
Total time of the journey
\(13.54+1.5=15.04\ \text{hours}\)
Converting \(0.04\ \text{hours}\) to minutes
\(0.04\times 60=2.4\)
So, the total time taken for the journey is \(15\ \text{hours and }2\ \text{minutes and }24\text{seconds}\)
Time when they reach their destination
\(7:30+15:2.4\approx 10:02:24\ \text{pm}\)

Answer:
AB = 2
Step-by-step explanation:
the triangles are similar so that means there is a constant ratio for each side length. so comparing the ratios from the bigger triangle to the smaller triangle, leaves us with 9/3 and 15/5. if you take those and divide them you get 3 for both of them which is the constant. so then in order to find the length of AB just take the side length of XY (6) and divide it by 3 (the constant ratio) and there you have your answer!
hope this helps.
given the following formula solve for y.
Answer:
D. y = x-2(w+z)
Step-by-step explanation:
w = (x-y)/2 -z
Add z to each side
w+z = (x-y)/2 -z +z
w+z = (x-y)/2
Multiply each side by 2
2(w+z) = (x-y)/2 *2
2(w+z) = x-y
Subtract x from each side
2(w+z) -x = x-y-x
2(w+z) -x = -y
Multiply each side by -1
-2(w+z) +x = y

Given that ZCFE ZCFA, mZCFB = 68°, and mZEFD= 62°, find the measure of ZAFD.
The measure of ZAFD is 50 degrees.
Based on the given information:
ZCFE is congruent to ZCFA.
mZCFB = 68°.
mZEFD = 62°.
To find the measure of ZAFD, we can use the fact that angles in the same segment of a circle are equal.
Since ZCFE and ZCFA are congruent, angle ZCFE is equal to angle ZCFA.
Therefore, mZCFA = mZCFE.
Now, let's find the measure of angle ZCFE:
mZCFE = mZCFB + mZEFD (Angle Addition Postulate)
mZCFE = 68° + 62°
mZCFE = 130°
Since ZCFA is congruent to ZCFE, we can conclude that mZCFA is also equal to 130°.
Now, to find the measure of ZAFD, we need to consider the angles in the quadrilateral ZAFD.
The sum of the angles in a quadrilateral is always 360°.
mZAFD + mZAFB + mZBFD + mZBFA = 360°
We know that mZAFB and mZBFD are equal to 90° because they are right angles (angle AFB and angle BFD are right angles in the diagram).
Therefore, we can rewrite the equation as:
mZAFD + 90° + 90° + mZBFA = 360°
Simplifying:
mZAFD + 180° + mZBFA = 360°
Rearranging the equation:
mZAFD + mZBFA = 360° - 180°
mZAFD + mZBFA = 180°
We know that mZBFA is equal to mZCFA, which is 130°.
Substituting the known values into the equation:
mZAFD + 130° = 180°
Subtracting 130° from both sides:
mZAFD = 180° - 130°
mZAFD = 50°
Therefore, the measure of ZAFD is 50 degrees.

A mother invests $6000 for her children's education, with a portion in a 4% CD account and the remainder in a 7% savings bond. The total interest earned is $360.
Let's assume the amount invested in the CD account is x dollars. Then, the amount invested in the savings bond will be the remaining amount, which is (6000 - x) dollars.
The interest earned from the CD account is given by 0.04x, while the interest earned from the savings bond is 0.07(6000 - x). The total interest earned after one year is $360, so we can set up the equation:
0.04x + 0.07(6000 - x) = 360
Simplifying the equation, we get:
0.04x + 420 - 0.07x = 360
-0.03x = -60
x = 2000
Therefore, the mother invested $2000 in the CD account (earning 4%) and $4000 in the savings bond (earning 7%) to accumulate a total interest of $360 after one year.

As a planner, you're targeting a 4% growth rate. If depreciation (delta) =0.03, capitaloutput ratio (c)=3,pi/Y=0.5, and savings out of capital income, 5(pi)=25%. At what rate should the wage earners and rural households save? (Note: Write in \%, no decimal)
If the modified Harrod-Domar Growth model, c(g+δ)=(sπ- sW)(π/Y) +sW, if you're targeting a 4% growth rate with δ= 0.03, c= 3, π/Y = 0.5 and sπ= 25%= 0.25, then the rate at which the wage earners and rural households should save is 5.67%
To find the rate, follow these steps:
Applying g= 4%= 0.04, δ= 0.03, c= 3, π/Y = 0.5 and sπ= 25%= 0.25 in the Harrod-Domar growth model, c(g+δ) = (sπ- sW)(π/Y) + sWA, we can find the value of sW .The left-hand side of the equation gives us investment, and the right-hand side gives us savings. Substituting these values we get 3(0.04+0.03)=(0.25+ sW)(0.5) +sW ⇒0.21= 0.125 +0.5sW +sW ⇒ 0.085= 1.5sW So, sW= 0.085/ 1.5= 0.0567= 5.67%Learn more about Harrod-Domar Growth model:

As the sample size becomes larger, the sampling distribution of the sample mean approaches a.
As the sample size rises, the sample distribution approaches a normal distribution.
The sample distribution approaches a normal distribution as the sample size grows. The sampling distribution's mean equals the population's mean if the number of consecutive samples is "infinite".
The Gaussian distribution is the official name for the normal distribution. However, the word "normal" was coined in the nineteenth century after a scientific inquiry revealed that numerous natural events appeared to "deviate from normal" from their typical values.
In his 1889 work Natural Inheritance, naturalist Sir Francis Galton popularized the notion of normal variability as the standard curve.

()) There are two cubes. The first cube has a volume of 1,000 cubic units. The second cube is smaller than the first, with sides only half as long. What is the volume of the second cube? D) cubic units Submit
Answer:
125 units^3
Step-by-step explanation:
Volume is l*w*h = V. A cube has all equal sides so wecan divide 1000 by 3 and get our side lengths.
You then divide the sides by 2 because the question says the second cubes sides are half the size
5*5*5 = 125
The volume of the second cube is 125 units³.
What is volume?In mathematics, ‘Volume’ is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.
Given that a cube has volume 1000 units³ and another smaller cube has smaller volume has side only half as long.
We need to find the volume of the second cube,
So, let the side of the first cube be x,
We know that the volume of a cube = side³
Therefore,
x³ = 1000
x = ∛1000
x = 10 units
Therefore, the second cube will have a side of 10/2 = 5 units
Volume of second cube = 5³ = 125 units³.
Hence the volume of the second cube is 125 units³.

solve for x using logarithm:
25^x-3(5^x)=0
Answer:
\(x = 0.68\)
Step-by-step explanation:
We would like to find out the value of x using logarithms of the given equation .The equation is ,
\(\longrightarrow 25^x - 3(5^x)=0\\\)
Add \(3(5^x)\) on both sides,
\(\longrightarrow 25^x = 3(5^x) \)
Using log to the base 10 on both sides, we have;
\(\longrightarrow log_{10}(25^x) = log_{10}\{3(5^x)\}\)
Recall that \( log(ab ) = log\ a + log\ b \) .
\(\longrightarrow log_{10}(25^x)=log_{10}3 + log_{10}5^x \)
Recall the properties of logarithm as \( log\ a^b = b\ log\ a \) .
\(\longrightarrow xlog25 = log_{10}3 + xlog_{10}5 \)
Again we can rewrite it as ,
\(\longrightarrow xlog(5^2)=log_{10}3+xlog_{10}5\\ \)
\(\longrightarrow 2x\ log_{10}5 = log_{10}3+xlog_{10}5 \\ \)
\(\longrightarrow 2x\ log_{10}5-x\ log_{10}5 = log_{10}5 \)
Simplify,
\(\longrightarrow x\ log_{10}5=log_{10}3 \)
Divide both sides by log5 ,
\(\longrightarrow x =\dfrac{log_{10}3}{log_{10}5} \)
Put on the values of log 3 and log5 ,
\(\longrightarrow x =\dfrac{0.47}{0.69} \)
Simplify,
\(\longrightarrow \underline{{\underline{\boldsymbol{ x = 0.68}}}}\)
And we are done!

Determine the cost of the points given the loan, interest rate, and number of points
purchased. Assume each point costs 1% of the loan amount:
$300,000, 4.4% APR, 1 points with 0.125% discount
The borrower would pay $3,000 for one point, which would result in a reduction of 0.125% on the interest rate, bringing it down to 4.3945%.
To determine the cost of the points in this scenario, we need to calculate 1% of the loan amount ($300,000), which is $3,000. Since the borrower is purchasing one point, the cost of the point would be $3,000.
Additionally, the borrower is receiving a discount of 0.125% on the interest rate for purchasing this point. To calculate the new interest rate after the discount, we can multiply the original interest rate (4.4%) by the discount percentage (0.125%), which gives us a reduction of 0.0055. We can then subtract this reduction from the original interest rate to get the new rate:
4.4% - 0.0055 = 4.3945%
So the borrower would pay $3,000 for one point, which would result in a reduction of 0.125% on the interest rate, bringing it down to 4.3945%.
