When the expression given as 6 + √27/4 - √3 is simplified, the value is 6 - 1/4√3

The expression is given as

6 + root 27over 4 - root 3

Mathematically, the expression can be represented as

6 + √27/4 - √3

Expand 27 as the product of 9 and 3

So, we have the following equation

6 + √27/4 - √3 = 6 + √(9 * 3)/4 - √3

Expand the products in the above equation

So, we have the following equation

6 + √27/4 - √3 = 6 + √9 * √3/4 - √3

Evaluate the square root of 9 in the above equation

So, we have

6 + √27/4 - √3 = 6 + 3/4√3 - √3

Evaluate the like terms in the above equation

So, we have the following equation

6 + √27/4 - √3 = 6 - 1/4√3

Hence, the value of the expression given as 6 + √27/4 - √3 is 6 - 1/4√3

The number of units that is needed to be manufactured and sold per month by the company to break even is 222 units

The first step is to write out the parameters given in the question

The sales price per unit is $50

The fixed cost per month is $4000

The variable cost per unit is $32

The formula for calculating the units needed to break even can be expressed as follows

Fixed Costs ÷ (Sales price per unit – Variable costs per unit)

4000/(50-32)

= 4000/18

= 222.2

Hence 222 units are needed to be manufactured per month

Answer:

Given that 2500 students entered the Teacher Education Program.

20% of the students are male. Thus,

Thus,

Thus, the ratio of the number of males to the number of females is evaluated as

Hence, the ratio of the number of females to the number of males is thus 4:1

We know that Emma has skydived 16 times, and also Emma has skydived twice as many times as Nico, so Nico has skydived:

So, Nico has skydived 8 times.

Finally, we know that Gus has skydived 4 more times than Nico, so:

Gus has skydived 32 times.

Answer:

-2

Step-by-step explanation:

You have to use rise over run. For example, to go from (-1,0) to (-2,2), you have to go up 2 squares and go left 1. That gives you 2/-1, which is -2. Hope this helps!

Step-by-step explanation:

a probability is always

desired cases / totally possible cases

a 50% probability means 1/2 or 0.5.

that means

desired cases = 1/2 × totally possible cases

at start we have

3 red

3 white

5 blue

that makes 5 + 3 + 3 = 11 totally possible cases and 3 desired cases.

so, the starting probability to pull a white marble is

3/11.

now, we need to say

(3 + x) = 1/2 × (11 + x) (= (3+x)/(11+x) = 1/2)

to make is simpler we multiply both sides by 2 (so we get rid of the 1/2 fraction).

6 + 2x = 11 + x

6 + x = 11

x = 5

we need to add 5 white marble to give us a 50% probability to pull a white marble.

we have then

3 red

3 + 5 = 8 white

5 blue

that makes 5+8+3 = 16 totally possible cases and 8 desired cases.

so, the probability is

8/16 = 1/2

=> our calculation was correct

The number of white marbles should be added to the bag to make the probability of pulling a white marble 50% will be 5.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

A bag contains 3 red marbles, 3 white marbles, and 5 blue marbles. only white marbles will be added to the bag.

Let 'x' be the number of white marble added. Then the equation is given as,

0.50 = (x + 3) / (x + 3 + 3 + 5)

Simplify the equation, then we have

0.50 = (x + 3) / (x + 3 + 3 + 5)

0.50 = (x + 3) / (x + 11)

0.50x + 5.5 = x + 3

0.50x = 2.5

x = 5

The number of white marbles should be added to the bag to make the probability of pulling a white marble 50% will be 5.

Step-by-step explanation:

The expression 26+8 as the product of the GCF and a sum is:

2(13+4).

Given we have the expression as 26+8

We need to find the greatest common factor of the numbers 26 and 8.

26 = 2 × 13

8 = 2 × 2 × 2

Multiply all the prime factors that both numbers share in order to determine the GCF:

Therefore, GCF = 2

Now we can write the expression as:

26 + 8

=2(13 + 4)

=2×17

=34

Hence we get the required expression as 2(13 + 4).

Answer:

C' = (15, 7)

Dilation by a scale factor of 3 with the origin (0, 0) as the center of dilation, followed by a translation of 1 unit up.

Step-by-step explanation:

If two triangles are said to be similar, their corresponding angles are congruent and their corresponding sides are in the same ratio.

Given vertices of triangle ABC:

To maintain similarity (and thus keep the corresponding angles of both triangles the same) but not maintain congruence, dilate triangle ABC.

Given:

If ΔABC is dilated by a scale factor of 3, with the origin as the center of dilation, B' = (3, 12).  If the triangle is then translated 1 unit up, B' = (3, 13), which matches the given coordinate of point B'.

Therefore, the series of transformations is:

Mapping Rule:  (x, y) → (3x, 3y + 1)

Therefore, the coordinates of point C' are:

⇒ C' = (3(5), 3(2) + 1) = (15, 7)

The value of x is 4 and 0

Algebra is a branch of mathematics that helps translate real-world problems or situations into mathematical formulas. Mathematical operations like addition, subtraction, multiplication, and division as well as variables like x, y, and z are needed to construct a valid mathematical expression. Coordinate geometry, calculus, and trigonometry are just a few of the mathematics topics that involve algebra. A simple algebraic equation is 2x + 4 = 8. Algebraic expressions are the result of performing operations on variables and constants, such as addition, subtraction, multiplication, division, etc. Consider that James and Natalie came up with the notion to arrange matchsticks into numerical patterns when they were fiddling with them.

Answer:

D) 24

Step-by-step explanation:

c + r = 30            Eq. 1

4r + 8c = 144       Eq. 2

r = rectangular tables

c = circular tables

From Eq. 1:

c = 30 - r             Eq. 3

Replacing Eq. 3 in Eq. 2:

4r + 8(30-r) = 144

4r + (8*30 + 8*-r) = 144

4r + 240 - 8r = 144

-4r = 144 - 240

-4r = -96

r = -96/-4

r = 24

from Eq. 3

c = 30 - r

c = 30 - 24

c = 6

Check:

from Eq. 2

4r + 8c = 144

4*24 + 8*6 = 144

96 + 48 = 144

The equation of line passing through (-4, -16) and (5, 2) are y = 2x – 8, y - 2 = 2(x - 5) and y + 16 = 2(x + 4)

An equation is an expression that shows the relationship between two or more numbers and variables.

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

The standard form for linear equation is:

y = mx + b

Where m is the slope and b is the y intercept

The equation of line passing through (-4, -16) and (5, 2) is:

y - (-16) = [(2-(-16))/(5-(-4))](x - (-4))

y + 16 = 2(x + 4)

y = 2x - 8

Answer:

a. Exponential decay

b. f(x) = a (1 - r)^x

c. f(x) = 25(1 - 0.06)^x

d. 16 terms

Explanation:

a. Does this problem represent exponential growth or decay? How do you know?

Each day the number of terms that you know is less than the day before, so there is a decrease in the vocabulary terms memorized. It means that the problem represents exponential decay.

b. Which exponential formula below will you use for this problem? Why?

The formula for the exponential decay is:

Where a is the initial value and r is the rate of decay.

So, the formula that you will use is f(x) = a (1 - r)^x

c. Write the formula for this specific problem. Explain how you know where each number goes in the formula.

The initial value is 25 terms and the decay rate is 6%, so the specific equation is:

d. How many terms will you remember seven days later for the test? Show all your work and explain your computations.​

Now, we need to replace the value of x by 7, so:
