Answer:

Alecia lives farther from school

Step-by-step explanation:

Georgia

we know that

The distance from the school to her home is 67/100 of a mile

[tex]\frac{67}{100}=0.67\ miles[/tex]

Alecia

we know that

The distance from the school to her home is

3/10 of a mile plus 4/10 of a mile

so

[tex]\frac{3}{10}+\frac{4}{10}=\frac{7}{10}=0.7\ miles[/tex]

Compare the distances

[tex]0.7\ miles>0.67\ miles[/tex]

therefore

Alecia lives farther from school

Final answer:

The answer explains that Georgia lives farther from school than Alecia based on the distances they walked.

Explanation:

Alecia: Walked 3/10 mile from school + 4/10 mile back home = 7/10 mile total distance.

Georgia: Walked 67/100 mile total distance.

Alecia vs. Georgia: Alecia walked 0.7 mile, Georgia walked 0.67 mile. Georgia lives farther from the school as 0.7 > 0.67 mile.

Answer:

Final simplified expression is 6.

Step-by-step explanation:

We have been given an expression [tex]216^{\frac{1}{3}}[/tex].

Now we need to simplify [tex]216^{\frac{1}{3}}[/tex] So let's do that by factoring 216 first so that we can have same repeating factor thrice

[tex]216^{\frac{1}{3}}[/tex]

[tex]=(6*6*6)^{\frac{1}{3}}[/tex]

[tex]=(6^3)^{\frac{1}{3}}[/tex]

Apply formula [tex](x^m)^n= x^{m*n}[/tex]

[tex]=6^{3*\frac{1}{3}}[/tex]

[tex]=6^{1}[/tex]

[tex]=6[/tex]

Hence final simplified form is 6.

Answer:

Step-by-step explanation:

0.41*2=0.82

0.82*2=1.64

divide by 2...pattern is 3.28,1.64,0.82,0.41

Another pattern with the same fourth term is one where to get the next term in the sequence we multiply the previous one by -2, and the first term is -0.41,

We have the pattern:

0.41, 0.82, 1.64, 3.28

Is ratter easy to see that it is a geometric sequence, such that each term is twice the previous term:

Now we just want to make another pattern that has the same fourth term, so we can play with the given pattern.

Suppose we start with -0.41, and instead of by 2, we multiply each time by -2, then we get:

And so on, so we just found another pattern that has the same fourth term, but behaves differently.

The answer is A because the rest of them for any given x you get 2 or more values of y

Let side B = X

Then side A = 2x

Side C = 2x +1

Mow you have x + 2x + 2x+1 = 76

Simplify:

5x +1 = 76

Subtract 1 from both sides:

5x = 75

divide both sides by 5:

x = 75 /5

x = 15

Side A = 2x = 2*15 = 30 cm

Side B = x = 15 cm

Side C = 2x +1 = 2*15 +1 = 30+1 = 31 cm

Unknown scale is 1.25

Step-by-step explanation:

Here size of fonts have been enlarged with a scale factor. Scale factor means a common factor by which a sequence is formed.

The given sequence will be a geometric sequence.

So common ratio between 3rd and 4th fonts = [tex]\frac{1.954}{1.563}=1.25[/tex]

This ratio will be same in 1st and second fonts = [tex]\frac{1.25}{1}=1.25[/tex]

So unknown scale size is 1.25

Answer: option a.

Step-by-step explanation:

The [tex]\lim_{x \to a} f(x)[/tex] give us information about the behavior of the function when the variable x gets closer to the value a. In other words, it tells us to what value y gets closer when x gets closer to the value a.

In this case we are evaluating the limits when:

Answer:

A) 0.335; B) 0.343; C) 0.599

Step-by-step explanation:

For part A,

To find the probability that the user has more than one infection per year, we can either add together the probabilities for 2, 3, 4 and 5; or we can add together the probabilities for 0 and 1 and subtract them from 1:

1-(P(X = 0)+P(X = 1))

= 1-(0.343+0.322) = 1-0.665 = 0.335

For part B,

The probability that the user has no infections per year is P(X = 0); this is 0.343.

For part C,

The probability that the user has between 1 and 3 infections (inclusive) per year is

P(1 ≤ X ≤ 3) = 0.322+0.201+0.076 = 0.599

The probabilities are as follows: A. An echinacea user is likely to experience more than one infection per year with probability 0.335. B. The likelihood of an echinacea user having no infections per year is 0.343. C. The probability that an echinacea user has between one and three infections, inclusive, is 0.599.

Sine and cosine do not have infinite range.

The range of secant excludes (-1, 1), so the only remaining possibility for the red curve is tan(x).

Answer:

4

Step-by-step explanation:

Given in the question a logarithm expression

[tex]7^(log_{49}16 )[/tex]

We will use Exponent of Log Rule

[tex]b^(log_{b}k ) = k[/tex]

here b = 7

        k = 16

So suppose

[tex]7^(log_{49}16 ) = x\\Take square on both sides\\(7^(log_{49}16 ) )^{2} = x^2\\49^(log_{49}16)= x^2[/tex]

Now, according to the rule

16 = x²

to find x only take square root on both sides of the equation

x = √16

x = 4

so [tex]7^(log_{49}16 )[/tex] = 4

Answer:

TRUE

Step-by-step explanation:

tanθ = 1/cotθ

cotθ = 0 when θ = ±(1/2)π, ±(3/2)π, … ±[(2n+1)/2]π.

∴ tanθ is undefined when θ = ±[(2n+1)/2]π.

secθ = 1/cosθ

cosθ = 0 when θ = ±(1/2)π, ±(3/2)π, , …, ±[(2n+1)/2]π.

∴ secθ is undefined when θ = ±[(2n+1)/2]π.

The tangent and secant functions are undefined for the same values of θ.

Answer:

True

1,400 bracelets in 3 and a half hours

Step-by-step explanation:

First you have to find how many minutes are in 3 and a half hours. 1 hour is 60 minutes, so 60 + 60 + 60 is 3 hours or 180 minutes and 30 minutes is a half an hour. Therefore 3 and a half hours equals 210 minutes. Set up an equal proportion: 100 bracelets / 15 min = x bracelets / 210 min. Use algebra to solve: 100 * 210 = 15x → 21000 = 15x → 1400 = x.

1400 bracelets can the factory produce in three and a half hours.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

A factory can produce 100 bracelets every 15 minutes.

So, In one minutes the factory produced

= 100 /15

= 20/3

Now, In three and a half hours ( 210 minutes) the factory can make

= 20/3 x 210

= 20 x 70

= 1400

Hence, In three and a half hours 1400 bracelets can be made.

Answer:

Part 1) [tex]m<ECF=90\°[/tex]

Part 2) [tex]m<AKB=77.5\°[/tex]

Part 3) [tex]m<ACF=75\°[/tex]

Step-by-step explanation:

Part 1) Find the measure of angle ECF

we know that

CF is tangent at point C

so

the radius EC is perpendicular to the tangent CF

therefore

[tex]m<ECF=90\°[/tex]

Part 2) Find the measure of angle AKB

we know that

The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite

[tex]m<AKB=\frac{1}{2}(arc\ AB+arc\ DC)[/tex]

substitute the values

[tex]m<AKB=\frac{1}{2}(50\°+105\°)=77.5\°[/tex]

Part 3) Find the measure of angle ACF

we know that

The inscribed angle is half that of the arc it comprises

[tex]m<ACF=\frac{1}{2}(arc\ AB+arc\ BF)[/tex]

substitute the values

[tex]m<ACF=\frac{1}{2}(50\°+100\°)=75\°[/tex]

Answer:

∠ ECF = 90°

∠AKB = 77.5°

∠ACF = 75°

Step-by-step explanation:

The given figure is a circle E.

Line CF is tangent at point C.

(1) To find measures of angle ECF

Since line FC is tangent at point C and radius ECis always perpendicular to the tengent.

So ∠ ECF = 90°

(2) Measure of angle AKB

By theorem of angle formed by two interesting chords.

∠ AKB = [tex]\frac{1}{2}[/tex] (arc AB + arc CD)

= [tex]\frac{1}{2}[/tex] (50 + 105) = [tex]\frac{1}{2}(155)[/tex]

∠AKB = 77.5°

(3) Measure of angle ACF

Since tangent chord angle = [tex]\frac{1}{2}[/tex] (intercepted arc)

m (∠ACF) = [tex]\frac{1}{2}[/tex] (m arc AB + m arc BC)

= [tex]\frac{1}{2}(50+100)[/tex]

[tex]\frac{1}{2}(150)[/tex]

∠ACF = 75°
