How many times larger is 8 x 108 than 2 x 104 ?

Answer:

1) -5+(-1)+7

-6+7

=1

2) 19+(-3)+6

16+6

=22

Answer:

1: 1

2: 22

Step-by-step explanation:

1 ) -5 + (-1) is -6, because they both have the same sign.

-6+7} when there is a negative and a postive, put the postive in front

so it will look like this 7-6 which is 1

2) 19+(-3) is basically 19-3, which is 16, and 16+6=22

Extra note:

when you see n+(-n), always remove the + sign and subtract

when you see -n+n, always switch the roles of the two

when you see -n+-n, remove the - sign and add it back later

when you see -n-n, think of -n+n

I hope these helps :)

Answer:

a soda can has diameter 2.5 and 4.8 find surface is divides by 1.98

Answer:

The solution is given below:

Step-by-step explanation:

Given that

The equation is 4.2x

It could present the total price for the no of goods

Here we take an example

The price per chips is $4.2

And, the number of chips purchased be x

And, the total price would be y

So if 5 chips were purchased, so the total price would be

y = $4.2 (5)

= $21

hence, the above represent the description

Answer:

(x,y)=(4,6)

Step-by-step explanation:

3x+4y=36

y=-1/2 x+8

step 1: substitute the value of y

[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]

step 2: solve equation for x

[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]

3x-2x+32=36

x+32=36

x=36-32

x=4

step 3: substitute the value of x

[tex]y=-\frac{1}{2} (4)+8[/tex]

Step 4: solve equation for y

[tex]y=-\frac{1}{2} (4)+8[/tex]

y=-2+8

y=6

there for the answer is

(x,y)=(4,6)

Answer:

The starting height of the raiders is 39 meters.

Step-by-step explanation:

Physically speaking, a free fall motion is an uniformly accelerated motion due to gravity. Mathematically, speaking the equation of motion for the height of an object under free fall is a second order polynomial (quadratic function).

Let [tex]h(t) = -9.8\cdot t^{2}-5\cdot t + 39[/tex] be the height of the riders, in meters, the starting height is the height evaluated at [tex]t = 0\,s.[/tex] Hence, we proceed to the determined the required data by direct evaluation:

[tex]h(0) = -9.8\cdot (0)^{2}-5\cdot (0) +39[/tex]

[tex]h(0) = 39[/tex]

The starting height of the raiders is 39 meters above the ground.

Blue square

Step-by-step explanation:

looking like rhombus because right angle is 90 degrees and a square has 4 right angles

Answer:

The slope is 2!

Step-by-step explanation:

To find the slope of a line, you must first find two points that are EXACTLY on the grid.

Two points I picked are (-1, -2) and (0,0).

Now count how many points the numbers are far from each other up and down. So, starting from (-1,-2) to (0,0), the points are two points away from each other vertically (on the y-axis)

Now find how far they are on the x-axis

Once again I counted and they are 1 point away from each other horizontally.

Now you need to turn these two points into a fraction.

Slopes are rise/run or y/x

So:

The slope is 2/1.

Also, the slope is positive as the line ascends (goes up).

If the line were negative or going down, the slope would be negative, but the line is positive.

So, the answer is 2!

Answer:

k=1/4

Step-by-step explanation:

x² - 5kx+ k=0  ....(1)

suppose 2 roots: a and 4a

(x-a)(x-4a)=0

x² - 5ax + 4a² = 0 ....(2)

compare (1) and (2): -5a = -5k              a=k

4a² = k                4a² = a   (substitute)

a(4a-1) = 0

a = 0 or a = 1/4        (if a=0   k=0 and x=0 is not the solution)

a = 1/4      k = 1/4

(a₂ = 1/4 * 4 = 1)

Answer:

k = 1/4.

Step-by-step explanation:

Let the roots be  r and 4r   and using the fact that sum of the roots = -b/a and product = a/c, we have:

r + 4r = -(-5k)

r*4r = k

5r = 5k

4r^2 = k

From the 3rd equation:

r = k, therefore:

4k^2 = k

4k = 1

k = 1/4.

Answer:

x int = (2/3,0)

y int = (0,4)

Step-by-step explanation:

x intercept y=0

6x+0=4

6x=4

x=4/6

x=2/3

(2/3,0)

y intercept x=0

6(0)+y=4

y=4

(0,4)

Answer:

(0,4) and ([tex]\frac{2}{3}[/tex], 0)

Step-by-step explanation:

6(0) + y = 4

y = 4

(0,4)

6x + 0 = 4

6x = 4

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

([tex]\frac{2}{3}[/tex], 0)
