The array shown has two numbers filled in: 2 and 7. What does the 2 mean in the
array? What does the 7 mean in the array?

Answer:

1) 0.25%

Step-by-step explanation:

Ratio= weight in g/ volume in ml

1. percent strength = 12.5× 10-³g /5ml × 100%

=0.25%

Answer:

0.25%

Step-by-step explanation: Convert mg to g (1g = 1000mg)

12.5mg/1000mg = 0.0125g/5ml ( 0.0025) x 100 = 0.25%

Answer:

M3 = 105°

angles on a straight line add up to 180°

M3 = 180 - 75

= 105°

Answer:

[3m - n = 2]

-3m - n + n = 2 + n

3m - n + 2

-3m/3 = n+2/3

m=1/3 n+2/3

Answer:

m=1/3n + 2/3

[2m + n = - 7]

-Let's solve for m.

2m+n=−7

Step 1: Add -n to both sides.

2m+n+−n=−7+−n

2m=−n−7

Step 2: Divide both sides by 2.

2m/2= −n−7/2

m= −1/2n + −7/2

Answer:

m= −1/2n + −7/2

Answer:[tex]x^{2}+\frac{11x}{5}-\frac{12}{5}[/tex]

Step-by-step explanation:

The roots are really just what x is when the equation is equal to zero. So, an equation with these roots would look like this:

(x+3)(x-4/5)=y

however, this is not standard form. To get standard form we will need to expand the equation using FOIL.

x^2+3x-4x/5-12/5=

x^2+11x/5-12/5

and that would be your answer.

Answer:

40

Step-by-step explanation:

Lets put the 3/4 at the beginning and expand this bracket :

3/4(x-4) = 27

3/4x - 3 = 27

Now we add 3 to both sides :

3/4x = 30

Now we times both sides by 4 :

3x = 120

Now we divide both sides by 3:

x = 40

Answer:

A. Three

explanation :

In Spherical Geometry, a triangle can have three right angles!

The correct answer is option D which is the difference between the mean times is about 16 times the mean absolute deviation of the data sets.

Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.

The difference between the mean times is about 16 times the mean absolute deviation of the data set.

127.9-127.4=0.5

0.26-0.23=0.03

0.5/0.03=16.6666

We can see that the ratio of the mean times difference is 16 times the mean deviation by solving the above.

Therefore the correct answer is option D which is the difference between the mean times is about 16 times the mean absolute deviation of the data sets.

Answer + Step-by-step explanation:

x² + 4x + 29 = 0

⇔ [x² + 4x] + 29 = 0

⇔ [x² + 4x + 4 - 4] + 29 = 0  (just add and subtract 4)

⇔ [x² + 4x + 4] - 4 + 29 = 0

⇔ (x + 2)² - 4 + 29 = 0   (Replace x² + 4x + 4 by (x + 2)²)

⇔ (x + 2)² + 25 = 0

⇔ (x + 2)² = -25  impossible because (x + 2)² > 0 and  -25 < 0

By solving a linear equation, we will see that the total cost for renting the bus is $90.

Let's say that the total cost is C.

When there are 20 students, each student should pay:

p = C/20

When the other 10 students are added (for a total of 30) each student pays:

p' = C/30.

We know that the cost for each of the original 20 students decreased by $1.50, so:

p' = p - $1.50

Then we have 3 equations to work with:

p = C/20

p' = C/30.

p' = p - $1.50

Now we can replace the first and second equations into the third one:

C/30 = C/20 - $1.50

Now we can solve this linear equation for C:

C/20 - C/30 = $1.50

C*( 1/20 - 1/30) = $1.50

C*(30/600 - 20/600) = $1.50

C*(10/600) = $1.50

C*(1/60) = $1.50

C = 60*$1.50 = $90

So the total cost for renting the bus is $90.

The correct answer is option D. Which is the even function is f (x) = x⁴.

The function in which when the sign of the input variable is changed the output remains the same is called the even function. Mathematically we can write it as f(x) = f(-x ).

let us check the given four options:-

A f(x) = √x ;  f(-x) = √-x  here f(x) ≠ f(-x)

B f(x) = x ;  f(-x) = -x    here f(x) ≠ f(-x)

C f(x)  = x³ + 1 ; f(-x) = -x³ + 1  here f(x) ≠ f(-x)

D f(x)  = x⁴  ;  f(-x) = (-x)⁴ = x⁴  here f(x) = f(-x)

We can see that in the option D the f(x) = x⁴ is an even function because f(x) = f(-x).

Therefore the correct answer is option D. Which is the even function is f (x) = x⁴.
