Answer:

[tex]A=1817\ \text{yards}^2[/tex]

Step-by-step explanation:

Given that,

The length of sign, l = 79 yard

Width, b = 23 yards

We need to find the area of his sign. It is in the form of a rectangle. The area of a rectangular shape is given by :

[tex]A=l\times b\\\\A=79\times 23\\\\A=1817\ \text{yards}^2[/tex]

So, the area of his sign is [tex]1817\ \text{yards}^2[/tex].

Answer:

  [tex]\text{c. }f(n)=3f(n-1);f(1)=2[/tex]

Step-by-step explanation:

The first term is 2, so part of the recursive definition is ...

  f(1) = 2

The common ratio is 6/2 = 3, so each term is 3 times the previous one. That part of the recursive definition is ...

  f(n) = 3·f(n -1)

These two parts of the definition match choice C.

Answer:

z=(-6)

Step-by-step explanation:

(2/3)*z=(-4)

2*z=3*(-4) --> We move the 3 from the left to the right part of the equation. It was dividing, so we move it multiplying.

2*z=(-12)

z=(-12)/2 --> It's the inverse case of before. 2 was multiplying, so we move it to the right by dividing it.

z=(-6)

The answer is 856 units^2

Answer:

856

Step-by-step explanation:

= 2 × (14×12 + 14×10 + 12×10)

= 2 × (168 + 140 + 120)

= 2 × 428

= 856

Answer:

-21

Step-by-step explanation:

3x-5=2

4x 2=2

2x-3=2

add them together you will get -21

I used long division to solve the problem

Answer:

x=20

Step-by-step explanation:

use proportions

121:11

or 11:1

take 10 and multiply it by 11 to get the length of the other side.

110

set the equation equal to that length

5x+10=110

-10 on both sides

5x=100

÷5 on both sides

x=20

Answer:

90°

Step-by-step explanation:

[tex](\pi /2) * 180 = 90[/tex]

Whenever you are required to transfer from Radians to Degrees, simply multiply the Numerator by 180° (180). Treat the [tex]\pi[/tex] as a variable such as x and y, and divide by the numerator.

Answer:

Final Value = 17.50 × (1 + 4/100)

Final Value = 17.50 × (1 + 0.04)

Final Value = 17.50 × (1.04)

Final Value = 18.2

Answer:

131.3 miles

Step-by-step explanation:

The two cars are moving from different directions. The total distance between the two cars = 118 miles + 256 miles = 374 miles.

Let us assume that the two cars meet at point O, let the distance between car c and O be d₁, the distance between car d and point O be d₂, hence:

d₁ + d₂ = 374 miles       (1)

Let speed of car d be x mph, therefore speed of car c = 2x mph (twice of car d). If it take the cars t hours to meet at the same point, hence

For car c:

2x = d₁/t

t = d₁ / 2x

For car d;

x = d₂/t

t = d₂/ x

Since it takes both cars the same time to meet at the same point, therefore:

d₁/2x = d₂ / x

d₁ = 2d₂

d₁ - 2d₂ = 0         (2)

Solving equation 1 and 2 simultaneously gives d₁ = 249.3 miles, d₂ = 124.7 miles

Therefore the distance from point of meet to Boston = 249.3 - 118 = 131.3 miles

   Both the cars will meet at 131.33 miles from Boston.

Given in the question,

Distance between two cars = 118 + 256 = 374 miles

Let these cars meet at a point P.

Let the distance between the car C and point P = 'x' miles

Therefore, distance between car D and point P = (374 - x) miles

Time taken 't' by car C to travel the distance 'x' miles,

[tex]\text{Time}=\frac{\text{Distance}}{\text{Speed}}[/tex]

[tex]t=\frac{x}{2v}[/tex]  -------(1)

Time taken 't' by the car D to travel (374 - x) miles,

[tex]t=\frac{(374-x)}{v}[/tex] ---------(2)

Substitute the value of 't' from equation (2) to equation (1),

[tex]\frac{x}{2v}=\frac{374-x}{v}[/tex]

[tex]\frac{x}{2}=374-x[/tex]

[tex]\frac{3x}{2}=374[/tex]

[tex]x=249.33\text{ miles}[/tex]

From the picture attached,

Distance between Boston and the meeting point = (x - 118) miles

                                                                                   = 249.33 - 118

                                                                                   = 131.33 miles

     Therefore, both the cars will meet at a point 131.33 miles distant from Boston.

Step-by-step explanation:

From the question, we are informed that there are 5 ¾ feet of lights to wrap around a pillar and that every time the lights wrap around, it uses up ⅛ ft of the lights.

The number of times that the lights can be wrapped around the pillar will be:

= 5 ¾ feet ÷ ⅛ ft

= 23/4 / 1/8

= 23/4 × 8
