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.

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?
Answers
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%

Halla el MCM de 63 y 77
Answers
Respuesta:
693
Explicación:
Tenemos que dividir ambos dígitos hasta que lleguen a 1.
No importa si uno de los números no se puede dividir, pero se debe iniciar desde los números más bajos: 2, 3, 4, 5, 7...
Cómo no hay una mitad exacta, empezaremos con tercia y continuaremos dividiendo.
63 ; 77 | 3
21 ; 77 | 3
7 : 77 | 7
1 ; 11 | 11
1 ; 1
Ahora que llegamos hasta 1, el MCM es la multiplicación de los números por los que hemos dividido a los dígitos. Solo falta multiplicarlos.
3*3*7*11= 693
MCM = 693
Espero te ayude ;)

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?
Answers
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]

4(8+y)=96 I need this answer if anyone knows it let me know
Answers
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
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.
Answers
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.

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)
