Tonya drove 343 miles the first day of her trip. how many days will it take her to drive the remaining 1,200 miles if she continues at the same rate?
Answer:
3.5 days
Step-by-step explanation:
Given
[tex]Day\ 1 = 343\ miles[/tex]
Required
Number of days to drive 1200 miles
Represent as ratio:
[tex]Day\ 1 = 343\ miles[/tex]
[tex]Ratio = 1 : 343[/tex]
For 1200 miles
[tex]Ratio = x : 1200[/tex]
Equate both ratios
[tex]x : 1200 = 1 : 343[/tex]
Express as fractions
[tex]x/1200 = 1/343[/tex]
Multiply by 120
[tex]x/1200 *1200= 1/343*1200[/tex]
[tex]x= 3.4985[/tex]
[tex]x= 3.5[/tex] --- approximated
In right triangle ABC shown below, the midpoint of hypotenuse AC is located at D and segment BD is drawn.
AB = 12 and BC =16, then explain why BD=10. Hint: consider what you know about the diagonals of a
rectangle.
9514 1404 393
Answer:
diagonal AC is 20, so all half-diagonals are 10. BD is one such.
Step-by-step explanation:
The length of hypotenuse AC is given by the Pythagorean theorem:
AC² = AB² + BC²
AC² = 12² +16² = 400
AC = √400 = 20
The midpoint of AC is 10 units from A and from C.
Consider point E that finishes rectangle ABCE. Then diagonals BE and AC meet at their midpoints, D. The diagonals of a rectangle are the same length, so the four half-diagonals are congruent:
AD = CD = ED = BD = 10
_____
Alternate solution
The "rise" from BC to D is half of AB, so is 6.
The "run" from AB to D is half of BC, so is 8.
The Pythagorean theorem tells you BD = √(6² +8²) = 10.

Step-by-step explanation:
A solar heating device can recharge (store heat) in a single sunny day enough to provide for the next two days. In other words, the only times that the solar heat must be augmented by some other heat source is when there are three or more consecutive cloudy days. During the heating season, a period of 120 days, the weather patterns are described by the following Markov chain:
Sunny Cloudy
Suuny 1/2 1/2
Cloudy 1/3 1/3
Using this information, construct another Markov chain which is capable of indicating when the solar heat must be augmented. Hint: Think carefully about your state definition.
Answer:
Step-by-step explanation:
Suppose the number of days is represented with the states(S) provided that a sunny day, with a maximum of three.
i.e.
S = (0, 1, 2, 3)
It implies that; if we assume that [tex]X_n=2[/tex], what this means is that today appears cloudy, then yesterday was cloudly as well while the day before yesterday was sunny.

4(8+y)=96 I need this answer if anyone knows it let me know
Answer:
y = 16
Step-by-step explanation:
Given
4(8 + y) = 96 ( divide both sides by 4 )
8 + y = 24 ( subtract 8 from both sides )
y = 16
Answer:
y = 16
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*(8+y)-(96)=0
4 • (y + 8) - 96 = 0
Pull out like factors :
4y - 64 = 4 • (y - 16)
4 • (y - 16) = 0
Solve : 4 = 0
This equation has no solution.
A non-zero constant never equals zero.
Solve : y - 16 = 0
Add 16 to both sides of the equation :
y = 16
Last year, Tim rode his bike a total of 50 3/8 miles. This year, he rode his bike a total of 258 3/4 miles. Which of the following explains about how much farther Tim rode his bike this year than last year? A. About 200 times farther; Subtract last year's distance from this year's distance to get 208 3/8.
Then round to the nearest hundred to get 200.
B. About 50 times farther; Round each distance to the nearest whole number.
Then multiply last year's distance by 50 to see that 259 is close to 50 × 5.
C. About 10 times farther; 258 is about 5 times 50, and 34 is 2 times 38, so multiply 5 × 2 to get 10.
D. About 5 times farther; Round each distance to the nearest whole number.
Then multiply last year's distance by 5 to see that 259 is close to 50 × 5.
Answer:
D

If 3/4 of the class likes soda and 3/5 of those who like soda prefer Coke, what PERCENT of the whole class that likes Coke?
Answer:
For soda =3/4
For coke= 3/5 X 3/4=9/20
Whole class is 1....
Therefore X% of 1 =9/20
Solving :
X/100 X 1 =9/20
X/100=9/20
20X =900
X= 900/20 = 45%

A local pizza shop has a membership program for frequent buyers. The membership costs $20 per month and members get a discounted price of $1.50 per slice of pizza. Shandra purchased a membership to this pizza shop. How much would Shandra have to pay the pizza shop if she bought 5 slices of pizza this month? What would be the monthly cost for x slices of pizza?
Answer:
Shandra would pay $27.50 for 5 slices
Cost = 20+1.50x
Step-by-step explanation:
Given
[tex]Membership = \$20[/tex]
[tex]Discounted\ Price = \$1.50[/tex] per slice
Solving (a): Cost of 5 slices
Represent the total price with y and the number of slice with x.
So, we have:
[tex]y = Membership + Discounted\ Price * x[/tex]
This gives:
[tex]y = 20+ 1.50* x[/tex]
In this case: x = 5.
So, we have:
[tex]y = 20+ 1.50* 5[/tex]
[tex]y = 20+ 7.50[/tex]
[tex]y = 27.50[/tex]
Shandra would pay $27.50 for 5 slices
Solving (b): Cost of x slices
This has been solved in (a).
[tex]y = 20+ 1.50* x[/tex]
[tex]y = 20+1.50x[/tex]
Hence, the cost of x slices is 20+1.50x

Answer:
592.83 ft^2
Step-by-step explanation:
First estimate the area of the rectangle:
Area rectangle = Base x Height = 20 * 36 = 720 ft^2
and then subtract from it the area of a semi-circle of radius 18/2 = 9 ft
Using the formula for the semicircle's area:
Semi-circle's area= pi * R^2 / 2 = 3.14 * 9^2 / 2 = 127.17 ft^2
Such gives us:
720 ft^2 - 127.17 ft^2 = 592.83 ft^2

Forty percent of all high school graduate work during the summer to earn money for college tuition for the upcoming fall term. Assuming a binomial distribution, if 6 graduates are selected at random, what is the probability that none of the graduates have a summer job
Answer:
[tex]0.0467[/tex] is the probability that none of the graduates have a summer job
Step-by-step explanation:
Here
P [tex]= 0.40[/tex] and n [tex]= 6[/tex]
Probability that none of the graduate gets job
this means that x = 0
P (x = 0) [tex]= ^6C_0 * (0.40)^0 * (0.60)^6[/tex]
P (x = 0) [tex]= 0.0467[/tex]
