Step-by-step explanation:

First one is #2

Second one is #1

I'm positive about this

Assuming 0x6A is given in base 16, first convert [tex]152_b[/tex] and [tex]6A_{16}[/tex] to a common base, say base 10:

[tex]152_b=1\cdot b^2+5\cdot b^1+2\cdot b^0=(b^2+5b+2)_{10}[/tex]

[tex]6A_{16}=6\cdot16^1+10\cdot16^0=106_{10}[/tex]

Then

[tex]b^2+5b+2=106[/tex]

[tex]b^2+5b-104=(b-13)(b+8)=0[/tex]

[tex]\implies b=13[/tex]

Answer:

The value of b is, 8

Step-by-step explanation:

Determine the value of b;

Given:

[tex](152)_b = 0x6A[/tex]             ....[1]

Since, 0x6A represents the hexadecimal form.

First convert this hexadecimal form into decimal form:

[tex](6A) = (6 \times 16^1)+(A \times 16^0) = (96)+(10 \times 1) = 96+10 = 106[/tex]

⇒[tex]0x6A = 106[/tex] (decimal form)

Now we have to convert this decimal form into octal

8  |  106

8   |  13   | 2

     |   1    | 5

          1

Then, the octal form we get, [tex](152)_8[/tex]

Substitute these in [1] we have;

[tex](152)_b=(152)_8[/tex]  

On comparing both sides we get;

b = 8

Therefore, the value of b is, 8

Answer: Last option

Step-by-step explanation:

1. According to the properties of exponents, you have that:

[tex]a^{-n}=\frac{1}{a^n}\\\\(a^n)^m=a^{mn}[/tex]

2. Then, he must simplify the expression as following:

[tex](4z^8)^{-3}={4^{-3}z^{8(-3)}=\frac{1}{64z^{24}}[/tex]

3. Therefore, as you can see, should have also applied the negative exponent to 4 to get [tex](4z^8)^{-3}={4^{-3}z^{8(-3)}=\frac{1}{64z^{24}}[/tex]

Answer:

The correct answer option is He should have also applied the exponent -3 to 4 to get [tex]4^{-3}z^{8 \cdot(-3)} = 4^{-3}z^{-24} = \frac{1}{64z^{24}}[/tex].

Step-by-step explanation:

The following expression was to be simplified by Mario:

[tex] (4z^8)^-3 [/tex]

Given this expression, we need to apply this rule on it in order to simplify:

[tex] (a b)^m = a^m \cdot b^m [/tex]

So we would get:

[tex] (4z^8)^-3 [/tex]

[tex]4^{-3} \cdot (z^8)^{-3}[/tex]

[tex]\frac{1}{4^3} \cdot z^{-24}[/tex]

[tex]\frac{1}{64z^{24}}[/tex]

This would be the right simplification for the given expression but by looking at Mario's work shown, we can conclude that:

He should have also applied the exponent -3 to 4 to get [tex]4^{-3}z^{8 \cdot(-3)} = 4^{-3}z^{-24} = \frac{1}{64z^{24}}[/tex].

Answer:

The option B (4 5/8,-2 3/4)  = (4.6 , -2.75) will be the coordinates belonging in the box.

Step-by-step explanation:

A.(4 3/4,-3 3/4) = (4.75,-3.75)

B.(4 5/8,-2 3/4)  = (4.6 , -2.75)

C.(4 1/4,-5 1/2)  = (4.25, -5.5)

D.(4 1/8,-2 3/5) = (4.125, -2.6)

The first point of line segment is: (5.5, -4.25)

second will be (4.75,-3.75)

third will be (4.6 , -2.75)

fourth will be (4.125, -2.6)

and fifth is  (3.75,-1.25)

The option C is not correct i.e not included in line segment.

The option B will be the coordinates belonging in the box.

The two little lines through the two sides of the triangle mean that they are the same length.

When two sides of a triangle are the same, the two lower inside angles are also the same.

Angle A is given as 50 degrees, so angle C is also 50 degrees.

The sum of the three inside angles need to equal 180 degrees, so angle B would equal 180 - 50 - 50 = 80 degrees.

Angle B = 80

Angle C = 50

Answer:

34,860

Step-by-step explanation:

In a sample of 32 residence, 24 take Vitamin C. From here we can get the proportion of residents who take Vitamin C, which is 24/32 = 3/4 = 0.75

0.75 in  percentage is 75%. This means 75% of the residents in sample take Vitamin C.

We can expect the same percentage of people in entire population to take Vitamin C.

Total population of city = 46480

Expected number of residents who take vitamin C in the city = 75% of 46480

= 0.75 x 46480

= 34860

This means, 34860 is an estimate of number of city residents who take Vitamin C supplement daily.

Based on the sample study and assuming its representativeness of the general population, it is estimated that approximately 34,860 residents of the city take a vitamin C supplement daily.

In the sample study, the proportion of residents who take vitamin C supplements daily is calculated by dividing the number of individuals who reported taking the supplement (24) by the total number of individuals in the sample (32). This yields a proportion of 0.75, or 75%. Then, we can apply this proportion to the total population of the city to estimate the number of residents who take vitamin C daily. Therefore, the estimated number is 0.75 * 46,480 = 34,860.

In conclusion, assuming that the small sample is representative of the larger population, we would estimate that "approximately 34,860" city residents take a vitamin C supplement daily.

The answer is 3 units up

Answer: ∠D.

Step-by-step explanation:

because they are in the same position (2nd letter placement)

If quadrilaterals CDEF ≅ MNPQ, then it follows that ∠N ≅ ∠D.

Hence ∠D is correct.

If CDEF and MNPQ are congruent,

Then it means they have the same shape and size.

In other words, all of their corresponding angles and sides are equal.

Therefore, if ∠C is congruent to ∠M,

∠D is congruent to ∠N,

∠E is congruent to ∠P, and

∠F is congruent to ∠Q.

This is because congruence is a relation of equality between two geometric figures.

So, if two triangles (or any other polygons) are congruent,

Then all of their corresponding angles and sides are equal.

Therefore, if CDEF ≅ MNPQ, then it follows that ∠N ≅ ∠D.

Divide the first number by the second number for each ratio:

A. 1 to 4 = 1/4 = 0.25 = 25%

B. 4 to 1 = 4/1 = 4 = 400%

C. 2 to 5 = 2/5 = 0.4 = 40%

The answer is C.

An equivalent ratio to 40% is 2 to 5, which is option C. The percentage is simplified by dividing it by the greatest common divisor to find its simplest ratio form.

To find a ratio equivalent to 40%, we first understand that percentages are a way of expressing a ratio where the second term is 100. Therefore, 40% is the same as saying 40 out of 100 or 40/100.

Next, we simplify this fraction to its lowest terms. Dividing both numerator and denominator by their greatest common divisor, which is 20 in this case, gives us 2/5. Thus, the ratio equivalent to 40% in its simplest form is 2 to 5, which corresponds to option C.

If we were to check the other options given, A (1 to 4) and B (4 to 1) are equivalent to 25% and 400% respectively, while D (5 to 2) is equivalent to 250%. Hence, these are not correct.

To illustrate the concept, let's consider an example. If the scale dimension is 4 cm, then to find the actual dimension using the proportion 1:2=4:x, we would cross-multiply to find x, which would be 8 cm, showing how ratios can be used to find corresponding values.

t 1/2 = 20

Try inserting the numbers in the half-life formula.

Answer:

93.75 gm.

Step-by-step explanation:

We have been given that an element has half life of about 20 days. We are asked to find the amount of 3000 gm sample left after 100 days.

We will use half-life formula to solve our given problem.

[tex]A=a\cdot (\frac{1}{2})^{\frac{t}{h}}[/tex], where,

A = Amount left after t units of time,

t = Time,

a = Initial amount,

h = Half-life.

Upon substituting our given values in above formula, we will get:

[tex]A=3000\cdot (\frac{1}{2})^{\frac{100}{20}}[/tex]

[tex]A=3000\cdot (0.5)^{5}[/tex]

[tex]A=3000\cdot 0.03125[/tex]

[tex]A=93.75[/tex]

Therefore, 93.75 gm of sample is left after 100 days.

Disclaimer: The number of cities in Asia will be 8 and not 888.

Elyse can choose from 960 different combinations of cities.

The different ways in which objects from a set can be picked, often without replacement, to produce subsets are known as permutations and combinations. When the order of selection is a factor, this selection of subsets is termed a permutation; when order is not a factor, it is called a combination.

We are given 4 continents, with a number of cities to choose from for Elyse to visit.

The table is like this:

Continent                          Number of cities

Europe                                           10

Asia                                                8

Africa                                              4

Australia                                         3

We use permutations and combinations to find the number of combinations Elyse will have to choose from.

We can say that for every 10 cities in Europe, she can choose any of the 8 cities in Asia. Similarly, for every 8 cities in Asia, she can choose any of the 4 cities in Africa. And similar is the case for Africa and Australia.

∴ Elyse can choose from a combination of 10*8*4*3 cities,

or, Elyse can choose from a combination of 960 cities.
