Tatum walks her dog 2/3 mile every day after school. How many miles does she walk her dog in 5 days
The number of miles that Tatutm walk her dog in 5 days is given by: Option B: 10/3 (in miles)
How to add two fractions?Let we have to add two fractions as:
[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]
Then we will find Lowest Common Multiple (LCM) of [tex]b_1[/tex] and [tex]b_2[/tex]. That will help to make the denominators same.
Once the denominators become same, the numerators can add up directly, giving us the final result of addition.
For this case, we're given that:
Each day, Tatum walks her dog 2/3 milesFor 5 days, the total distance her dog walked = 2/3 + 2/3 + 2/3 + 2/3 + 2/3
Since denominators are same, thus:
[tex]\dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} = \dfrac{2+2+2+2+2}{3} = \dfrac{10}{3}[/tex]
We could've easily done it as: 2/3 + 2/3 + 2/3 + 2/3 + 2/3 = 5 times 2/3 = [tex]5 \times \dfrac{2}{3} = \dfrac{5 \times 2}{3} = \dfrac{10}{3}[/tex]
Thus, the number of miles that Tatutm walk her dog in 5 days is given by: Option B: 10/3 (in miles)

2x-y=8
x+2y=4
for the system of equation above, what is the value of x+y?
Answer:
4
Step-by-step explanation:
2x-y=8 ---> y= 8-2x
substitute y=8-2x into x+2y=4
x + 2(8 - 2x) = 4
x + 16 - 4x = 4
-3x = -12
x = -12/-3
x = 4
substitute x=y into y=8-2x
y = 8 - 2(4)
y = 8 - 8
y = 0
therefore,
x+y= 4+0

In a hydroelectricity production, water falls from a dam into a turbine wheel 49 m below. What is the velocity of water at the turbine?
A) 0 m/s
B) 15.5 m/s
C) 31 m/s
D) 46.5 m/s
Answer:
C: 31 m/s
Step-by-step explanation:
It falls from a dam.
Thus;
Initial velocity; u = 0 m/s
Height; h = 49 m
Acceleration due to gravity is 9.8 m/s²
To solve for the final velocity this, we will use Newton's third equation of motion;
v² = u² + 2gh
v² = 0² + 2(9.8 × 49)
v = √960.5
v ≈ 31 m/s

Answer:
B reflected over y, translated up
Step-by-step explanation:
The left-right reversal means there was a reflection over a vertical line. The only one among the offered choices is the y-axis.
If the lines are reflected over the y-axis, the points on the y-axis don't move. The intercepts would still be 2 and 5 after the reflection.
However, the y-intercepts have moved up 3 units to 5 and 8.
Lines g and h were reflected over the y-axis and translated up 3 units.

Mrs. Williamson had 18 students in her homeroom at the beginning of the school year and 24 students at the end of the year. What was the approximate percent increase in the number of students in Mrs. Williamson’s homeroom?
25%
33%
57%
75%
Answer:
25%
Step-by-step explanation:
An easy way to figure this out is just by dividing the initial amount of students (18) by the current amount of students (24), and then subtracting 1.
So, 18/24 = 0.75 (aka 75%), and 1 - 0.75 = 0.25 (aka 25%)

Equation: 2x + 1 = 9x - 13
There are two chairs in each row.
Step-by-step explanation:
Looking at the problem, we see that Hue can form two rows of chairs with 1 left over, or 9 rows if she gets 13 more. With that information we can create the equation 2x + 1 = 9x - 13. Now let's solve for x.
2x + 1 = 9x - 13
What we can do first is subtract 9x from both sides. This is done so all of the variables are on one side. Thus that becomes...
2x + 1 - 9x = -13
Now, combine -9x and 2x to get -7x.
-7x + 1 = -13
Now subtract 1 from both sides. This is done so we solve for x directly.
-7x = -13 - 1
Subtract -1 from -13 to get -14.
-7x = -14
Now divide both sides by -7.
x = -14/-7
Divide -14 by -7 to get 2. Remember, dividing two negatives gives you a positive!
x = 2
With that, the equation is solved. There are 2 chairs in each row.

the fastest 3 runners in a race qualify for the next event. how many different groups of Runners could advance to the next event from a race that has seven runners
Answer:
35 different groups of 3 runners can be selected
Step-by-step explanation:
Here, we want to simply calculate the number of 3 runners that can advance in a race from a total of 7
What we want to do here is to simply get different groups of 3
So, we have it that we simply want to know the number of different ways we can select 3 from a total of 7
We can simply use combination for this;
We have the general combinatorial as;
nCr = n!/(n-r)!r!
With respect to this particular question, n = 7 and r = 3
So we have;
7C3 = 7!(7-3)!3! = 7!/(4)!3! = 35

Se sabe que el virus SARS-CoV-2 es de forma aproximadamente esférica cuyo diámetro del virus se ha encontrado para colocar entre 50 nanómetro a 140 nanómetro. Halle la dimensión para dicho volumen a) L2T b) L3 c) L4 d) ML3
Answer:
L³
Step-by-step explanation:
De la pregunta anterior se nos dice que el diámetro del virus esférico
= 50 - 140 millas náuticas
Radio = 50 - 140 nm / 2
= 25 - 70 millas náuticas
El volumen de una esfera es
= 4/3 πr³
Usando el análisis dimensional
4/3 = constante
π = constante
[r] = Dimensión de longitud = L
Por lo tanto, la dimensión del volumen de la esfera = L³
Your ship sinks and you swim to a nearby island. On this island, the inhabitants do not use money. The island residents use island fruit as money.
If 60 bananas = 20 coconuts
35 figs = 15 oranges
10 coconuts = 25 figs
200 figs = 1 boat
How many bananas would you need to purchase a boat to get off the island?
Answer:
240 bananas
Step-by-step explanation:
You would need 8 sets of figs. 10 coconuts is equal to 25 figs so you need 80 coconuts. You would need enough bananas to get 4 sets of coconuts. 60*4 = 240
Answer:
To buy the boat you would need 240 bananas.
Explanation:
3 bananas = 1 coconut
1 coconut = 2.5 figs
200 figs (price of boat) = 80 coconuts
80 coconuts (price of boat) = 240 bananas
