260 ÷ 8 1/8 =

convert the fraction to a decimal

1 ÷ 8 = 0.125

260 ÷ 8.125 = 32

Answer:

Step-by-step explanation:

a). tan(75°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

                  = [tex]\frac{11}{k}[/tex]

    k = [tex]\frac{11}{\text{tan}(75)}[/tex]

    k = 2.947

    k = 2.95 cm

b). cos(52°) = [tex]\frac{16}{s}[/tex]

    s = [tex]\frac{16}{\text{cos}(52)}[/tex]

    s = 25.988

    s ≈ 25.99 cm

c). sin(5°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

               = [tex]\frac{16.1}{q}[/tex]

    q = [tex]\frac{16.1}{\text{sin}(5)}[/tex]

    q = 184.727

    q ≈ 184.73 cm

Answer:

x = 23.33333

y = 35

Step-by-step explanation:

3x+2y=70

Geometric figure: Straight Line

Slope = -3.000/2.000 = -1.500

x-intercept = 70/3 = 23.33333

y-intercept = 70/2 = 35

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 35/1 so this line "cuts" the y axis at y=35.00000

y-intercept = 70/2 = 35

Calculate the X-Intercept :

When y = 0 the value of x is 70/3 Our line therefore "cuts" the x axis at x=23.33333

x-intercept = 70/3 = 23.33333

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 35.000 and for x=2.000, the value of y is 32.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 32.000 - 35.000 = -3.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = -3.000/2.000 = -1.500

Geometric figure: Straight Line

Slope = -3.000/2.000 = -1.500

x-intercept = 70/3 = 23.33333

y-intercept = 70/2 = 35

Answer: Each shirt costs $1.25, and each hat costs $2.5.

Step-by-step explanation:

Let x= Cost per T-shirt, y = Cost per Hat.

As per given,

3x+3y=11.25        (i)

4x+2y=10             (ii)

Multiply 4 to equation (i)

12x+12y=45          (iii)

12x+6y= 30             (iv)

Eliminate (iv) from (iii), we get

6y= 15

⇒ y = 2.5

Put value of y in (i)

3x+3(2.5)=11.25

⇒3x+7.5=11.25

⇒3x= 3.75

⇒x= 1.25

Hence, each shirt costs $1.25, and each hat costs $2.5.

Answer:

1/81

Step-by-step explanation:

P(H,H,H,H)=16/81

fourth root of 16/81= 2/3

so the probability of getting tails would be 1/3

probability of getting 4 tails would be:

P(T,T,T,T)=(1/3)^4

=1/81

The probability of getting 4 tails when the coin is thrown 4 times is 1/81

We have:

P(Head 4 times) = 16/81

This means that:

P(Head)^4 =  16/81

Take the 4th root of both sides

P(head) = 2/3

The probability of a tail is calculated as:

P(tail) = 1 - P(Head)

This gives

P(tail) = 1 - 2/3

P(tail) = 1/3

When thrown 4 times, we have:

P(tail)^4 = (1/3)^4

P(tail) = 1/81

Hence, the probability of getting 4 tails when the coin is thrown 4 times is 1/81

The number of dimes cannot be 10 because the number of dimes in the jar will be equal to 12.

The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities to compare them.

As per the data in the question,

The ratio of Dimes to pennies: 3 : 8

Number of Pennies in jar = 32

Assume that the number of Dimes in the jar is x.

So, the number of dimes will be,

x = (32 × 3)/8

x = 12 Dimes.

Weight limit of an elevator = 1800 pounds

Average weight of each person who comes in the elevator = 160 pounds

Quantity of items with them = 3 pounds

Let the number of people who can ride the elevator at one time be x.

Which means :

[tex] =\tt 160x + 3 = 1800[/tex]

[tex] = \tt160x = 1800 - 3[/tex]

[tex] = \tt160x = 1797[/tex]

[tex] =\tt x = \frac{1797}{160} [/tex]

Answer:

 4.50

Step-by-step explanation:

4 = Whole number. 1 = Numerator. 2 = Denominator. To get 4 1/2 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction.

The decimal form of  4 and 1/2  is 4.5

Decimal is a fraction written in a unique form. The dot notation is used to represent the fraction form.

Therefore, 4 and 1/2 in decimal form is represented as follows;

Mixed fraction = 4  1 / 2

Improper fraction = 9 / 2

decimal form of  1 / 2 = 0.5

Therefore, 4 1 / 2 = 4.5
