What is 5/10+1/5 to this problem please help me

1 answer:

5 0

Let's look at it like this:
5/10+1/5 = (5/10) + (1/5)
5/10 = 0,5
1/5 = 0,2
so it's 5/10 + 1/5 = (5/10) + (1/5) = 0,5 + 0,2 = <u>0,7 </u>

1.18. A fish tank has a base, B, with an area, in square inches, modeled by B(x) = 2x + 6x + 4.

Alekssandra [29.7K]

Answer:

The volume of fish tank is $V(x)=2x^3+12x^2+22x+12$

Step-by-step explanation:

Area of Base of fish tank = $Length \times Breadth$

We are given that A fish tank has a base, B, with an area, in square inches, modeled by $B(x) = 2x^2 + 6x + 4.$

So, $Length \times Breadth =2x^2 + 6x + 4.$

Height of tank = x+3

Volume of tank = $Length \times Breadth \times Height$

So, Volume of tank = $(2x^2 + 6x + 4)(x+3)$

Volume of Tank = $2x^3+6x^2+4x+6x^2+18x+12=2x^3+12x^2+22x+12$

Hence The volume of fish tank is $V(x)=2x^3+12x^2+22x+12$

A student runs 100 meters in 11 seconds. What is the speed of the student?

DiKsa [7]

100m= 0.621371 miles

11 seconds = 0.0030556 hours

s=d/t

0.0621371miles/0.0030556hours = 20.3355miles/hours

The<br> What is the slope of the line?

Shtirlitz [24]

Answer:

-1

Step-by-step explanation:

Slope is calculated with the general equation $\frac{x_{2}-x_{1} }{y_{2}-y_{1}}$ where you compare the difference between two sets of data points on the slope.

I will use the points (-2, 0) and (0, -2).

$\frac{-2-0{} }{0-(-2){}}$

This gives us -2/2 or a slope of -1
