Answer: s(s+4)=7, 7 shelves
Step-by-step explanation:
I think it's easiest to find these type of answers by finding the common factors of a number. First 77, they are 1×77 & 7×11.so you can have 11 rocks on 7 shelves or 7 rocks on 11 shelves. The question states the number or rocks on the shelf is more than the number of shelves, so you must have 11 rocks on 7 shelves. You know you have 77 rocks, so the equation must equal 77. I plugged 7 in for s in the equations to determine the correct answer. 7(7+4)=77.
Answer: 28.5 square units.
Step-by-step explanation: Separate the figure into a rectangle and a triangle. Count the length and width of the rectangle. The length of the rectangle is 8 units and the width is 3 units. To find the area use the formula l*w. 8*3=24.
Next find the area of the triangle section. The triangle is 3 units tall and 3 units wide. To find the area use the formula 1/2(l*w). 3*3=9. 9/2=4.5.
Finally add the areas of the rectangular section and the triangular section. 24+4.5=28.5.
To find slope, use the formula:
(y2-y1)/x2-x1)
So here is what it will look like:
(9--7)/(1--3)
Since you are subtracting a negative, then it turns unto a positive so you are adding the numbers together.
(9+7)/1+3)
16/4
4
The slope of the line is 4/1 or 4. Which means that you will go up or "rise" 4 and go to the left or "run" 1.
Hope this helps!
Answer:
ok so first you add all the prices together.
$9:00+$7:00+$8:00+$6:00+$4:00=34
then divide 34 by the number of prices.
34/5
then you get the mean
$6.8 is the mean
