Answer:

(3,11)

Step-by-step explanation:

Turn both equations into linear equations:

y=2x+5

y=5x-4

Then, just graph both equations.

Find the point where the two lines intersect. That point of intersection is the solution. That coordinate is (3,11).

How much larger is 6 times 10 to the 5th power compared to 2 times 10 to the 3rd power

lora16 [44]

Answer:

Either 10 times or 598,000.

Step-by-step explanation:

6 x 10 ^ 5 = 600,000

2 x 10 ^ 3 = 2,000

If we are figuring out the exact number, 600,000 - 2,000. If we are finding out how many powers larger, count.

600,000 - 2,000 = 598,000

600,000 is 10 times larger than 2,000.

A football player is running the length of a 100 yard long football field. For the first part of the field, he runs at a rate of

notka56 [123]

Answer:

$\frac{2}{5}$ th part of the field is covered in the second sprint.

Step-by-step explanation:

A football player is running the length of a 100 yard long football field.

Let player sprints x yards with the speed = 2 yards per second.

So time taken to cover x yards player will take time = $\frac{x}{2}$ seconds

Now rest distance (100 - x) yards when covered with the speed of 4 yards per second, so time taken to cover this distance = $\frac{Distance}{Speed}$

= $\frac{100-x}{4}$ seconds

Now total time taken by the player can be represented by the equation

$\frac{x}{2}+\frac{100-x}{4}=40$

Now we can solve this equation for the value of x.

$\frac{2x+100-x}{4}=40$

x + 100 = 40×4

x + 100 = 160

x = 160 - 100 = 60 yards

And length of the second part will be = 100 - 60 = 40 yards

Now the fraction of the field covered by the player in second sprint will be

= $\frac{40}{100}$

= $\frac{2}{5}$ or 40%

Therefore, $\frac{2}{5}$ th part of the field was covered in second sprint.

What is the product of (7 x 10^-5) x (5 x 10^-8) (7 x 10^-5) x (5 x 10^-8) = ? x 10^?

arsen [322]

Answer:

$3.5\times10^-^1^2$

Step-by-step explanation:

$(7 \times 10^-5) \times (5 \times 10^-8)$

Evaluate

$(7 \times 5)\times(10^-^5\times10^-^8)$

$35\times10^-^5^-^8$

$35\times10^-^1^3$

$35\times10^1\times10^-^1^3$

$3.5\times10^1^-^1^3$

$3.5\times10^-^1^2$

Thus, the answer is $3.5\times10^-^1^2$
