Huh? what do you mean
Does this mean -5 over 3
or -3 over 5??? Or what does that mean??? PLEASE HELP
Answer:
That’s -5 over 3 ! :)
Step-by-step explanation:
The -5 is above/over the 3
3 over -5 would look like 3/-5 and the picture you are showing has -5/3.
You can make a solar hot-dog cooker by shaping foil-lined cardboard into a parabolic trough and passing a wire through the focus of each end piece. How far from the bottom should the wire be placed?
Answer:
The wire should be placed at a height of 2.25 inches from the bottom
Step-by-step explanation:
With the assumption that the shape of the solar hot-dog cooker is a parabola. we have the equation for the shape given as y = a·x² + b·x + c
Whereby the coordinates of the vertex is taken as (h, k) = (0, 0), we have;
c = 0
∴ y = a·x² + b·x
From the diagram, we have;
When x = 6, y = 4
When x = -6, y = 4
Which gives;
4 = a·(-6)² + b·(-6) = 36·a - 6·b
4 = 36·a - 6·b.........................................(1)
4 = a·(6)² + b·(6) = 36·a + 6·b
4 = 36·a + 6·b........................................(2)
Subtracting equation (1) from equation (2) gives;
4 - 4 = 36·a - 6·b - (36·a + 6·b) = -12·b
0 = -12·b
b = 0
Therefore;
4 = 36·a - 6×0
a = 4/36 = 1/9
The focus = F(h, k + p)
p = 1/(4·a) = 1/(4 × 1/9) = 1/(4/9) = 9/4 in = 2.25 inches
The coordinates of the focus, F = (h, k + p) = (0, 9/4) = (0, 2.25)
Therefore, the wire should pass through the focus and placed at 2.25 inches above the bottom.

if x equals 3 cubed what does this problem equal 2x= If x = 33:
2x = ?
Answer:
2x = 54
Step-by-step explanation:
The given information;
x = 3^3
solve
x = 27
(beacuse 3^3 = 3 * 3 * 3 = 27
find 2x:
2x = 2 * x
x= 27
2 * 27 = 54
2x = 54

Six cousins inherited a total of StartFraction 5 Over 8 EndFraction of their great aunt’s assets, which they divided evenly. What fraction of their great aunt’s assets did each cousin inherit?
Answer:
For us to determine the answer to this item, we simply have to divide the given fraction of the great aunt’s property that is to be divided among the cousins by 6.
N = 5/8 / 6
The value of N in the equation is 5/48 or 0.104. Thus, each of the cousins will receive 10% of the great aunt’s property.
Answer:
5/48

multiply the first and third terms
-20 times 1 equals -20. take the -1
*what are two numbers that multiply together that equals -20 but add to equal -1?
-5 times 4 equals -20
-5 plus 4 equals -1
(r-5)(r+4)
1 x^2 + 8 x + 12
multiply the first and third terms
12 times 1 equals 12. take the 8
*what are two numbers that multiply together that equals 12 but add to equal 8?
6 times 2 equals 12
6 plus 2 equals 8

A school sold brownies and cupcakes at a bake sale. There were 592 total items available for sale. All 286 brownies were sold. Of the cupcakes for sale, 49 did not sell. How many cupcakes did sell at the bake sale? Select the correct equation to solve. A. 592 - 286 - 49 = c B. 592 - 286 + 49 = c C. 592 + 286 - 49 = c
Answer:
A. 592 - 286 - 49 = c
Step-by-step explanation:
A school sold brownies and cupcakes at a bake sale. There were 592 total items available for sale. All 286 brownies were sold. Of the cupcakes for sale, 49 did not sell. How many cupcakes did sell at the bake sale?
Total number = 592
Total number of brownies = 286
The cup cakes for sale = 592 - 286
= 306 cupcakes.
49 of the cupcakes did not sell
The cupcakes that sold = 306 - 49
= 257 cupcakes were sold.
Therefore, the correct equation to solve. A. 592 - 286 - 49 = c

A fish was swimming 3 in a half feet below the water surface at 7:00 a.M. Four hours later, the fish as at a depth that is 5 one fourth feet below where it was at 7:00 a.M. What rational number represents the position of the fish with respectto water surface at 11:00 a.M
Answer:
8 3/4 below sea level
Step-by-step explanation:
Given that:
Depth of fish at 7:00 A. M = 3 1/2 feets below sea level
Depth at 11:00a.m (4 hours later) = 5 1/4 feets below it's position at 7:00 a. M
Rational number to represent position of fish with respect to the water surface at 11:00 a. M
Position at 11:00 a. M :
Addition of the two depth distances given :
(3 1/2 + 5 1/4)
7/2 + 21/4 = (14 + 21) / 4 = 35 / 4
35/4 = 8 3/4 feets below sea level
Answer:
8.75, 8 3/4 or 35/4
Step-by-step explanation:
3 1/2 + 5 1/4
=(3+5) + (1/2 + 1/4)
=8 + (2/4 + 1/4)
=8 + 3/4= 8 3/4
=8 3/4= 35/4

Write the following number in Scientific Notation.
Explain what you did to get your answer
560,000,000,000,000,000
Answer:
5.6 * 10^17.
Step-by-step explanation:
There are 17 digits after the 5 .
So it's 5.6 * 10^17.
Note that the first number must lie between 1 and 10.
I don't really understand which number we have to write in scientifc notation but I am assuming it is the number 560,000,000,000,000,000.
Ok so, 560,000,000,000,000,000 in scientific notation is 5.6 x 10^17.
This is because if you count the number of spaces behind the decimal point of 5.6 it is equal to 17. So, you would write the answer 5.6 x 10^17.
