Round off 3. 55 to one significant figure

1 answer:

Answer:

3.6

Step-by-step explanation:

We must first clarify how a number is rounded.

To round a number to unity we have to look at the first number after the comma.

If this number is less than 5 (1, 2, 3, 4) we should not do anything, but if that number is 5 or greater (5, 6, 7, 8, 9) we must add a unit to the number.

That is to say:

<5 do nothing

=> 5 round to the next number (+1)

So in the case of 3.55 it would be.

3.55 = 3.6

A liquid at temperature 7575F is placed in an oven at temperature 450450. The temperature of the liquid increases at a rate 77 t

hichkok12 [17]

Answer: $\dfrac{dT(t)}{dt}=77\times (450-T)$

Step-by-step explanation:

Given

The temperature of the liquid is $75^{\circ}F$ placed in an oven with temperature of $450^{\circ}F$ .

Initially difference in temperature of the two

$\Delta T=450-75\\\Rightarrow \Delta T=375^{\circ}F$

According to the question

$\Rightarrow \dfrac{dT(t)}{dt}=77\cdot \Delta T\\\\\Rightarrow \dfrac{dT(t)}{dt}=77\times (450-T)\quad [\text{T=75}^{\circ}F\ \text{at t=0}]$

Henry sells rings for $8 dollars each his expenses are $1.50 per ring plus $91 for supplies how many rings does he need to sell

Ne4ueva [31]

Henry needs to sale 14 rings for his revenue to equal his expenses.

Step-by-step explanation:

Given,

Selling price of ring = $8

Expense on one ring = $1.50

Cost of supplies = $91

Let,

x represent the number of rings.

Expenses = 91+1.50x

Revenue = 8x

Equal expenses means;

Revenue = Expenses

$8x=91+1.50x\\8x-1.50x=91\\6.5x=91$

Dividing both sides by 6.5

$\frac{6.5x}{6.5}=\frac{91}{6.5}\\x=14$

Henry needs to sale 14 rings for his revenue to equal his expenses.
