What is the answer to − 4/7 = 5/2t ( its a one step equation)

The given figure is a rectangle.

Given angles are- m∠BDC = 47°, m∠CAB = 52°, and m∠BEC = 99°

The sum of the angles m∠BDC = 47°, m∠CAB = 52° is the measure of  m∠BEC  which is 99°

This is sufficient to prove. Measure of angle A and D are 90 degrees each as they are right angles triangles. So, inner angle A is 90-52 = 38 degrees. Inner angle D will be    90-47  =43 degrees.

Measure of triangle AED = 180 degrees

Let inner E = x

then, 38+43+x=180

x=99 degrees

Outer E and inner are vertical angles and so, they are same.

Moreover, triangles AED and BEC are same so E is 99 degrees

Step-by-step explanation:

3.56 x 10⁻⁵

the exponent of 5 tells you to move the decimal 5 places

the negative sign tells you to move the decimal to the left.

Equation Given: 3.56 x 10^-5  

Simple Explanatio: Lets start with this 10^-5 since the exponents is a negative you must subtract the exponent from the base and after you do so this is what your left with -5 and now since we have done the work lets rewrite the answer as 3.56 x 10^-5 the equation may not be changed but that's how i was told to do it and now solve. The decimal in 3.56 will be moved to the left five times because this equation has an negative exponent not a positive so you should end up with the simple answer of 0.0000356

Answer:

x = 5/2

Step-by-step explanation:

Isolate x by adding 2x to both sides, obtaining:  5 - 2x + 2x = 2x.  Then 5 = 2x, and dividing both sides by 2 results in x = 5/2.

The polynomial 55° + 6st - 85° - 6t has 4 terms and a degree of 10 after it has been fully simplified.

To determine the number of terms in a polynomial, count the separate algebraic expressions that are added or subtracted. In this case, the polynomial is composed of four distinct terms: 55°, 6st, -85°, and -6t.

Next, the degree of a term in a polynomial is the highest power of its variable. Examine each term to identify the variable and its corresponding exponent. The term 55° has a degree of 0 since any nonzero constant raised to the power of 0 is 1. Both 6st and -6t have a degree of 2, as the variables s and t are raised to the power of 1. Lastly, the term -85° has a degree of 1.

To find the overall degree of the polynomial, identify the term with the highest degree. In this case, it is the term 6st, which has a degree of 2. Therefore, the fully simplified polynomial has four terms and a degree of 2, making the correct statement: "It has 4 terms and a degree of 10."

Complete question :-

ANSWER: D

Answer:

5.23 years, the time at which the coin has increased in value to $150.

Step-by-step explanation:

Use the exponential function f(t) = 4*2^t.

Substitute $150 for f(t):  $150 = 4*2^t.

Simplify this by dividing both sides by 4:  $150/4 = 2^t, or $37.50 = 2^t.

Next, solve for the value of t.  To do this, take the common log of both sides, obtaining:

log 37.50 = t*log 2.  Thus, t = [log 37.50] / [log 2].  Evaluate this using a calculator:

t = 1.57403 / 0.30103 = 5.23 time units.  For example, this could be 5.23 years.

Answer:

It will take about 17.7 years, or almost 18 years, for the coin to be worth $150.

Because the initial year was 2016, the coin is predicted to be worth $150 in 2034.

Step-by-step explanation:

When dealing with a quadratic equation, you usually assign the following name to the coefficients of the variables:

[tex] ax^2+bx+c=0 [/tex]

So, [tex] a [/tex] is the coefficient of [tex] x^2 [/tex], [tex] b [/tex] is the coefficient of [tex] x [/tex] and [tex] c [/tex] is the constant term.

In your case, the coefficient of [tex] x^2 [/tex] is -3, so [tex] a=-3 [/tex]

The coefficient of [tex] x [/tex] is -2, so [tex] b = -2 [/tex]

The constant term is 6, so [tex] c = 6 [/tex]

Call that number x.

Then rewrite as equation:

4x+6=7x

solve for x

6=3x

2=x

So the number is 2.

Check that 2 is the number by following the original wording, mentally.

Hey there!!

Let's take the number as 'x'

4 times the number is 4x

This is increased by 6

We will have to add 6.

... 4x + 6

7 times a number is 7x

... 7x

Both these values are equal.

Hence,

... 4x + 6 = 7x

... 6 = 3x

... x = 2

Hence, the number is 2.

The complete statement is:

There were 59 bacteria after 5 hours

The initial population of the bacteria is given as:

[tex]a =100[/tex]

The proportion left after each hour is given as:

[tex]b = 90\%[/tex]

An exponential function is represented as:

[tex]f(x) = ab^x[/tex]

Substitute values for (a) and (b)

[tex]f(x) = 100 \times (90\%)^x[/tex]

Express percentage as decimal

[tex]f(x) = 100 \times (0.9)^x[/tex]

After 5 hours, the value of x is 5

i.e. x = 5

So, we have:

[tex]f(x) = 100 \times (0.9)^5[/tex]

Evaluate the exponent

[tex]f(x) = 100 \times 0.59049[/tex]

Multiply

[tex]f(x) = 59.049[/tex]

Approximate

[tex]f(x) = 59[/tex]

Hence, there were 59 bacteria after 5 hours

for anyone in the future that needs this the answer is The rule (x,y) ----> (x+2, y-4) represents a translation 2 units RIGHT and 4 units DOWN

Step-by-step explanation:

A translation is a transformation that moves every point in a figure in the same direction by the same amount. The rule (x, y)→(x+2, y−4) represents a translation of 2 units right and 4 units downwards

A translation is a transformation that moves every point in a figure in the same direction by the same amount. It is also a sort of transformation in which each point in a figure is moved the same distance in the same direction resulting in the same figure again.

For any graph, if the value of x is increased it moves in the right direction while it moves in the left direction if the value is decreased.

Similarly, For any graph, if the value of y is increased it moves upwards while it moves in downwards if the value is decreased.

Now, as per the given rule of transformation, (x, y)→(x+2, y−4), the graph will translate 2 units right and 4 units downwards.

Hence, The rule (x, y)→(x+2, y−4) represents a translation 2 units right and 4 units downwards.

Answer:

Intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

Step-by-step explanation:

Required vector is consists of the two components

vx= 2+4=6 units  and vy= 1 unit and vx ⊥ vy

We will use Pythagorian theorem to find intensity of the vector v

v∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 units

The angle ∡α between vector and east direction we wil find with tanα

tanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

The percentage decrease in price from $4.59 to $4.09 is 10.9%, while the percentage increase from $4.09 to $4.59 is 12.2%. Therefore, the percentages of change are not the same and the percentage increase is a greater change.

To calculate the percentage decrease in price from $4.59 to $4.09, we subtract $4.09 from $4.59, then divide by the original price of $4.59, and multiply by 100: (($4.59 - $4.09) / $4.59) * 100 = 10.9%. Therefore, the percentage decrease is 10.9%.

For the percentage increase from $4.09 back to $4.59, we similarly subtract $4.09 from $4.59, divide by the 'new' original price of $4.09, and multiply by 100: (($4.59 - $4.09) / $4.09) * 100 = 12.2%. Therefore, the percentage increase is 12.2%.

The resultant decrease and increase percentages are not the same. The percentage increase of 12.2% is a greater change compared to the 10.9% decrease.

To calculate the median: you want to organize all the numbers in it's data so it should look like this:  2, 5, 5, 8, 10, 12, 18, 20.

Now that it is organized look for the middle number so 9 is our median. I got this by adding 8 + 10 which equals 18 then dividing it by 2. So anytime you have 2 middle numbers add them then divide it by 2 it will always be your median.

To determine the mode: look for the number the occurs the most. I only see two 5's so the answer is 5 for our mode.

To determine the mean: Add all the numbers together then divide it by how many numbers there are so there are 8 numbers divide it by 8 after we add them.

2+5+5+8+10+12+18+20= 80 divide it by 8 and it equals 10. So 10 is the mean.

Answer:

Step-by-step explanation:

We will use the conditional probability in this case

We use conditional probability when two cases occur are dependent.

So by using:

[tex]\frac{P(A\capB)}{P(B)}[/tex]

Here, A is the event of experience needed.

And B is the event of part-time

Substituting the values in the formula we get:

[tex]\frac{6}{14}=.42[/tex]

Intersection of experience needed and part-time is 6

And part-time total is 6+8=14

To get in percent we will multiply it by 100

42% is the required probability.
