Answer:
<em>$40 </em>will be the total cost of the ribbon.
Step-by-step explanation:
To find the cost of ribbon to be put on the edges of rectangular banner, we need to:
1. Find the perimeter of the rectangle.
2. Multiply the perimeter with the per foot cost to find the total cost.
Let us find the perimeter first:
Perimeter of a rectangle is given as:
Here, the dimensions of rectangle are 4ft by 6ft.
So, perimeter = 
It is given that per foot cost is $2.
Total cost of the ribbon = 
<em>$40 </em>will be the total cost of the ribbon.
Answer:
Step-by-step explanation:
To get the zeros of the expression 2x(x - 5)(x+7), we are going to equate the expression to zero and find the corresponding value of x as shown;
2x(x - 5)(x+7) = 0
2x = 0
x-5 = 0
x+7 = 0
From 2x = 0
x = 0/2
x = 0
From x-5 = 0
x = 0+5
x = 5
From the equation x+7 = 0
x = 0-7
x = -7
Hence the values of the zeros are {-7, 0, 5}
Answer:
1,Let us suppose that the height of the ladder is h and the horizontal distance of the ladder from the wall is d, then we use these two important trigonometric functions; the sine and the cosine.
h = sin 78 * 8 m and d = cos 78 * 8m where sin 78 = 0.9781 and cos 78 = 0.2079
With the given values, I expect you to do the two multiplications yourself. You will obtain a near to 8 m answer for the height h and a near to 1.7 m answer for the distance d.
2, The ship is 15 km from the port.
3,30m The ship must travel 15.6km 10 km 8. A rectangular field is 40 m long and 30 m wide. Carl walks from one corner of the field to the opposite corner along the edge of the field. Jade walks across the field diagonally to arrive at the same corner. Tip How much shorter is Jade's shortcut? Show your work. Sketch a diagram Carl-40m ade - b?= C² first. 40m. Jade = a't 62=(3 30' + 402 c 900 + 1,600 e? C² =2,5 U0 %3D C=/2500 C=50 10m shorter. jade shortcut is 172
