Answer:
6
Step-by-step explanation:
Find out how many boys makeup the class.
100% = 40
1% = 40 ÷ 100 = 0.40
40% = 0.40 x 40 = 16
Find 25% of the class.
25% = 0.40 x 25 = 10
40 - 25 = 15% of the boys wear shirt jacs.
16 - 10 = 6
Which of the following inequalities is true?
The American antelope (pronghorn) and the wildebeest are among the fastest mammals on the planet,
particularly at running long distances. The maximum recorded speed for the antelope is 88.5 km/h, which it
can sustain for nearly one kilometer.
On the other hand, the distance, d, in kilometers that the wildebeest can run in t hours is given by the equation
d=80.5t
Assuming both animals are running at constant speeds, which animal can run faster?
Choose 1 answer:
The American antelope
B
The wildebeest
They can run at the same speed.

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
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
4

Answer:
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.

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)

0.4 repeating as a fraction for a mixed number
Answer:
Step-by-step explanation:
1.Rewrite the decimal number as a fraction with 1 in the denominator
2.Multiply to remove 1 decimal places. Here, you multiply top and bottom by 101 = 10
3.Find the Greatest Common Factor (GCF) of 4 and 10, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,
so the answer is

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

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.
