Answer:

61

Step-by-step explanation:

Here's a neat trick when you have an odd number of consecutive numbers.

Call the middle number k

Then the smaller number is k-1

The larger number is k + 1

The two ones will cancel.

k-1 + k + k-1 = 180

3k = 180

k = 180/3

k = 60

Therefore the largest number is k + 1 = 60 + 1 =61

Answer:

Step-by-step explanation:

To make the problem easier to solve, we will set it up as the equation of the length of time of each class times the number of classes equals the total amount of minutes. However, since we don't know the number of classes, we'll symbolize our two unknowns with two variables.

75x + 45y = 705

(75x + 45y)/15 = 705/15

5x + 3y = 47

y = (47-5x)/3

It looks like we can't simplify the equation any more, so now it is a matter of trial and error. The minimum number of Saturday classes means the maximum number of weekday classes. We first will test for the maximum by assuming there are no Saturday classes, then will work our way up until x is an integer.

If x = 0

(47-5(0))/3 = 47/3 = 15.6666

If x = 1

(47-5(1))/3 = 42/3 = 14

This works. Therefore, the maximum number of weekday classes is 14, or choice b.

The width = 8 meters

Step-by-step explanation:

The length: a (m)

The width: b (m)

We cannot have a negative length and a negative width: a>b>0

Eq. I: a=2b-4

Eq. II: ab=96

Substitute the value of a from Eq. I into Eq. II: (2b-4).b=96

Solve for b:

(2b-4).b=96

2[tex]b^{2}[/tex]-4b-96=0

[tex]b^{2}[/tex]-2b-48=0

[tex]b^{2}[/tex]+6b-8b-48=0

b.(b+6)-8.(b+6)=0

(b+6).(b-8)=0

b=8; b=-6

As mentioned above, b>0. Therefore, b=8

Conclusion: if the area of the rectangle is 96 square meters then its width is 8 meters.

The width of the given rectangle is 8 units.

A rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Let's say the length of the rectangle is L and the width is W

Given that,

The length of a rectangle is four meters less than twice its width.

So,

L = 2W - 4

And,

Area = 96 square meter

LW = 96

Now by substituting

2W² - 4W = 96

W² - 2W - 48 = 0

W² -8W + 6W - 48 = 0

W(W - 8) + 6(W - 8) = 0

(W + 6)(W - 8) = 0

W = 8, -6 since distance cannot be negative so it will be 6 meters.

Hence "The width of the given rectangle is 8 units".

Answer:

5.6 miles

Step-by-step explanation:

Let's set up a proportion using the following setup.

[tex]\frac{miles }{minutes}=\frac{miles }{minutes}[/tex]

We know Maya can run 7 miles in 80 minutes.

[tex]\frac{7miles }{80minutes}=\frac{miles }{minutes}[/tex]

We don't know how many miles she can run in 64 minutes. Let's say she can run x miles in 64 minutes.

[tex]\frac{7miles }{80minutes}=\frac{x miles }{64 minutes}[/tex]

[tex]\frac{7}{80}=\frac{x}{64}[/tex]

We want to solve for x (miles in 64 minutes). Therefore, we must isolate x on one side of the equation.

x is being divided by 64. The inverse of division is multiplication. Multiply both sides of the equation by 64.

[tex]64*\frac{7}{80}=\frac{x}{64}*64[/tex]

[tex]64*\frac{7}{80}=x[/tex]

[tex]64*0.0875=x[/tex]

Answer:

12/18=2/3

Step-by-step explanation:

You should add up every marbles to find out how many marbles are in total. Then, you should add the green and black marbles. There are 4 black marbles, and 8 green marbles, which results 12 black+green marbles. Then you should make a fraction 12/18, because you are finding the probability of the green+black marbles out of the total marbles. If you simplify, you get 2/3.

The probability of randomly selecting a green or black marble is 12/18.

Probability is the ratio that determines how likely an event is to occur from a set of possible events.

Total number of green marbles = 8

Total number of black marbles = 4

Total number of yellow marbles = 6

Total number of marbles = Total number of green marble + Total number of black marbles + Total number of yellow marbles = 18

P(selecting a green marble) = Total number of green marbles/Total number of marbles

= 8/18

P(selecting a black marble) = Total number of black marbles/Total number of marbles

= 4/18

P(selecting a green or black marble) = (Total number of green marbles + Total number of black marbles)/Total number of marbles

= (8 + 4)/18

= 12/18

Therefore, we have found the probability of randomly selecting a green or black marble to be 12/18.

Explicación paso a paso:

Dado el conjunto de un triángulo equilátero con cada uno de sus lados en progresión geométrica, si el primer triángulo mide un lado de 1 cm y una razón común de 2 cm, para obtener el lado del triángulo 29, usaremos la fórmula para calcular el enésimo término de la progresión geométrica. expresado como;

Tn = ar ^ (n-1)

a es el primer término

n es el número de términos

r es la razón común.

Dados los siguientes parámetros

a = 1, r = 2 y n = 20 (ya que estamos buscando el lado del vigésimo triángulo)

Sustituyendo los parámetros dados en la fórmula para obtener el lado del triángulo 20, tendremos;

T20 = 1 (2) ^ 20-1

T20 = 1 (2) ^ 19

T20 = 2 ^ 19

T20 = 524,288 cm

Por lo tanto, la medida de la longitud de un lado del vigésimo triángulo equilátero es 524,288 cm.

Perímetro del vigésimo triángulo equilátero = 3 × 524,288 = 1,572,864cm

Answer:

(-2, 6)

Step-by-step explanation:

Since you want a 1 to 7 ratio, you want to divide the line into 2 parts, where one part has a length of 1 and the other has a length of 7. So the total length of the line is 8.

Start by looking at the difference in the X and Y coordinates.

X = | -4 - 12 | = | -16 | = 16

Y = | 7 - -1 | = | 8 | = 8

You could calculate the length of the line using pythagorian's theorem, but that's not needed. Simply use similar triangles. We have a right triangle with legs of length 16 and length 8. We want a similar triangle that is 1/8th as large (to get the desired 1 to 7 ratio). So divide both legs by 8, getting lengths of 16/8 = 2, and 8/8 = 1.

Now add those calculated offsets to point A.

A has an X coordinate of -4 and B has an X coordinate of 12 and the X coordinate for C must be between those limits. So calculate -4 + 2 = -2 to get the X coordinate for C.

The Y coordinate of A is 7 and the Y coordinate of B is -1. And since the Y coordinate must be between then, you have 7 - 1 = 6.

So the coordinates for C is (-2, 6)
