3. Una caravana migrante, procedente de Honduras debe recorrer 5 km en 4 días si quiere alcanzar al tren conocido como la Bestia que los conducirá al Norte de México, el primer día debido al intenso calor solo avanzan 1200 metros, el segundo día ya los espera un retén militar pero aun así avanzan 1 2/3 km, el tercer día caminan un kilómetro y medio. Si quieren llegar a tiempo para tomar el tren, ¿Cuánto debe recorrer la caravana el último día? A) 18/29 B) 19/30 C) 20/31 D) 21/32
Answer:
B) 19/30
Step-by-step explanation:
Se deben recorrer 5km en total, en números fraccionarios se recorren:
1er día:
1200m = 1.2km = 6/5km
2do día:
1 + 2/3km = 5/3km
3er día:
1.5km = 3/2km
La suma da:
6/5km + 5/3km + 3/2km = 36/30km + 50/30km + 45/30km = 131/30km.
5km son 150/30km.
150/30km - 131/30km = 19/30 km
La respuesta es:
B) 19/30Work out the size of angle of x

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 1) = 2. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 1 = 2. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - nine halfs plus twelve = thirty-three halfs.
Add: the result of step No. 2 + 5/

Step-by-step explanation:
The sum of 4[tex]\frac{1}{2}[/tex] and 8[tex]\frac{3}{14}[/tex] is 12[tex]\frac{5}{7}[/tex].
What is addition?Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.
Let the required number be n.
According to the question,
the sum of 4[tex]\frac{1}{2}[/tex] and n is equal to 12[tex]\frac{5}{7}[/tex].
In numeric form,
4[tex]\frac{1}{2}[/tex] + n = 12[tex]\frac{5}{7}[/tex]
Simplifying,
9/2 + n = 89/7
Substituting constant to term one side,
n = 89/7 - 9/2
n = 115/14
n = 8[tex]\frac{3}{14}[/tex]
Therefore, the number is 8[tex]\frac{3}{14}[/tex].

Negative or positive 576(-999)(-1)(-1)(-3)
Answer:
Positive
Step-by-step explanation:
neg x neg = pos
neg x neg = pos
pos x pos x pos = pos
Answer:
Positive.
Step-by-step explanation:
Start with parenthesis, we have a negative x negative = positive times the next negative = negative times the last parenthesis which is negative so negative times negative = positive. Then times the positive by the remaining number outside parenthesis and get positive times a positive = positive.
How can you find a function that has
roots?
The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.
Answer:
The roots of a function are the x-intercepts.

The volume of a square that is 2 feet on all sides is ?
Answer:
8 cubic feet
Step-by-step explanation:
2*2*2=8
Assuming you are talking about a cube, the volume would be the side^3. In this case you said all sides are 2 feet long then the volume would be:
2^3 ft^3 or 8 cubic feet!
A mosaic tile is shown below. Dan wants to cover a 600-square-inches area. How many mosaic tiles does Dan need?
Answer:
B. 30
Step-by-step explanation:
The mosaic tile has a trapezoidal shape, so that its area can be determined as follows;
Area of a trapezium = [tex]\frac{1}{2}[/tex](a + b)h
where: a and b represent the length of its plane sides, and h is the height.
Area of a mosaic tile = [tex]\frac{1}{2}[/tex](4 + 6) 4
= 10 x 2
Area of a mosaic tile = 20 square inches.
But, Dan wants to cover a 600 square inch area.
So that the number of tiles needed = [tex]\frac{600}{20}[/tex]
= 30
The number of mosaic tiles needed by Dan is 30.

If two dice are rolled, what is the probability that their sum will be 10, given that both dice are odd?
a. 1/6
b. 1/7
c. 1/8
d. 1/9
Answer:
I think it is either 1/6 or 1/8
Hope it helps :)
The probability that the sum of the numbers on two dice will be 10 is 1/12.
What is probability?
Probability is the chance of happening an event or incident. It is calculated as the ratio of the possible cases to the total number of cases.
When two dice are rolled, total possible outcome = (6²) = 36
Number of ways to get a sum of 10 is 3. That is {(6, 4), (5, 5), (4, 6)}.
Hence, the probability to get a sum of 10
= number of possible cases/ total number of cases
= 3/36
= 1/12

I need to know the all the blanks including the equation on the bottom and y intercept and slopes
Answer:
See answers below
Step-by-step explanation:
Using the coordinates from the table (0, 12) and (1, 14)
m = 14-12/1-0
m = 2/0
m = 2
Hence the slope of the table is 2
y intercept occurs at x = 0
Substitute m = 2 and (0,12) into the equation y = mx+c
12 = 2(0) + b
12 = b
b = 12
Hence the y-intercept is 12
Get the equation
Recall that y = mx+c
y = 2x + 12
Hence the required equation is y = 2x+12
