Answer:

20%

Step-by-step explanation:

65 and 78 are both multiples of 13. Divide both by 13, we get 5 and 6.

If we use 5 as our main value (100%), 6 would be 120% as adding 1 to the main number (5) increases it by 20%. So 6 is a 20% increase from 5.

Answer:

The probability that the next spin will land on blue is 0.12.Step-by-step explanation:

The result of the several spins are as follows:

Color           Frequency

Red                  18

Blue                   9

Green               18

Yellow              19

Purple               12

TOTAL             76

Compute the probability that the next spin will land on blue as follows:

Thus, the probability that the next spin will land on blue is 0.12.

Answer:

i don't think you can (but i could be wrong)

Step-by-step explanation:

my thinking is that since there is still an unknown variable even after you've multiplied that there can't be an equivalent expression

Answer:

a = -36/7

Step-by-step explanation:

55 + 7a = 19

(55 - 55) + 7a = (19 - 55)

7a = -36

7a/7 = -36/7

a = -36/7  the fraction can't be simplified any further

The expression has the approximate value between 6 and 7 will be √42 which is 6.48.

When the original integer is multiplied by itself, the result is a square root. The result generated when a quantity multiplies itself is known as the number of the square.

The expression has the approximate value between 6 and 7 clear the all the apply.

a. √36 = 6

b. √38 = 6.16

c. √42 = 6.48

d. √50​ = 7.07

The expression has the approximate value between 6 and 7 will be √42 which is 6.48.

Then the correct option is C.

Answer:

m<PRQ=15°

Step-by-step explanation:

so we're given that PQ and RQ are sides of a regular 12-sided polygon (dodecagon)

a regular polygon is a polygon that has all angles be the same measure AND have all sides be the same length

because of that, PQ=RQ, and ΔPQR is isoceles

now we need to find what the question is asking for: m<PRQ

because of base-angles theorem, m<PRQ=m<RPQ

we need to find m<PQR

a dodecagon is 1800° in measure

and we need 1/12th of that measure, since <PQR is 1 out of the 12 interior angles on the dodecagon (a dodecagon has 12 vertecies, so 12 angles). Also because the polygon is regular, every interior angle has the same measure.

so find the measure of <PQR

<PQR= 1/12*1800=150°

now to find the measure of <PRQ:

there are 180° in a triangle

so subtract 150° from 180°

180°-150°=30°

30° is the sum of the base angles (<PRQ is one of the base angles in a triangle)

the base angles are the same measure, so that means the measure of <PRQ is 1/2 the measure of the sum of the base angles

therefore m<PRQ=15°

hope this helps!

Answer:

m∠1 = m∠3 = m∠5 = m∠7 = m∠9 = m∠11 = 76°

m∠2 = m∠4 = m∠6 = m∠8 = m∠10 = m∠12 = 104°

Step-by-step explanation:

Vertical angles are congruent.  When lines are parallel, corresponding angles are congruent.

m∠1 = m∠3 = m∠5 = m∠7 = m∠9 = m∠11 = 76°

m∠2 = m∠4 = m∠6 = m∠8 = m∠10 = m∠12 = 180 - 76° = 104°

Answer:

Tasa efectiva anual= 0.1722= 17.22%

Step-by-step explanation:

Dada la siguiente información:

Tasa de interes anual= 16% capitalizable mensualmente

Primero, debemos calcular la tasa nominal mensual:

Tasa mensual= 0.16 / 12= 0.01333

Ahora, usando la siguiente formula, la tasa efectiva anual:

Tasa efectiva anual= (1 + i)^n - 1

Tasa efectiva anual= (1.01333^12) - 1

Tasa efectiva anual= 0.1722= 17.22%

Answer:

408.2cm

Step-by-step explanation:

Given data

Area of base= 25πcm^2

Height= 8cm

Let us find the radius of the cylinder

Area= πr^2

25π= πr^2

25= r^2

r= √25

r= 5cm

Let us now find the surface area

SA=2πrh+2πr^2

Substitute

SA= 2*3.14*5*8+ 2*3.14*5^2

SA= 251.2+ 157

SA= 408.2cm

Hence the surface area is  408.2cm

Answer:

1200

Step-by-step explanation:

We can gather from what's given that y=20xy represents the total number of bottles produced in the given time in seconds, which is x. When x=1, y=20, This means that each second the machine can make 20 soda bottles. Each minute is 60 seconds, so when x=60, y=20*60 =1200 soda bottles.

Answer:

1140 households

Step-by-step explanation:

The results of a computer survey of 80 households in Westville are shown in the table.

So from the table we can see that 6 households have 3 numbers of computers.

So the probability is [tex]$\frac{6}{80}$[/tex]

Therefore, the probability of number of houses from a total of 15,200 houses to have exactly three computers is = [tex]$\frac{6}{80} \times 15200$[/tex]

                                                          = 1140 houses

Step-by-step explanation:

V = (π)r^2(h)

R = 1/2 diameter

   = 24/2 = 12

   = 12

H = 12

V = (π)12^2(12)

V = (π)144(12)

V = (π)1728

V = 5428.67

Answer:

43in

Step-by-step explanation:

Let the length of the pieces be x and y

Since the total length is 258in, then;

x+y = 258... 1

If One piece is five times the length of the other, then x = 5y ....2

Substitute 2 into 1

From 1:

x+y = 258

5y+y = 258

6y = 258

y = 258/6

y = 43

Since x = 258-y

x = 258-43

x = 215

Hence the length of the shorter piece is 43in
