Answer:

Difference = 2.25°

Step-by-step explanation:

Here we are given that at depth the Temperature T is inversely proportional to the depth x.

$T$ ∝ $\frac{1}{x}$

$T= 4500 \times \frac{1}{x}$

Where 4500 is constant

Now we have to find the difference in the temperature at 1200 mts and 3750 mts

1. x=1200

$T= 4500 \times \frac{1}{x}$

$T= 4500 \times \frac{1}{1200}$

$T= 3.75$

2. x=3750

$T= 4500 \times \frac{1}{x}$

$T= 4500 \times \frac{1}{3750}$

$T=1.2$

Hence Difference is

T = 3.75 -1.20

= 2.25

Therefore The difference of the temperature at 1200 mts and 3750 mts is T=2.25°

there is $3080 in the math department fund. They need to deposit enough money in the fund to pay for a shipment work $2800, and

tiny-mole [99]

Answer:

3080+d > = 3300

Step-by-step explanation:

The first question to ask is how much money do they need in the fund?

They need the shipment costs plus the future shipment costs

2800+500 = 3300

They have 3080

Let d = how much they need to deposit

How much they have plus how much they need to deposit must be greater than or equal to how much they need.

3080+d > = 3300

Which equation represents a circle with the same radius as

sattari [20]

Answer :

$(x+1)^2+(y-1)^2=4^2$ and $(x+1)^2+(y-1)^2=16$

Step-by-step explanation:

Given : A circle with the same radius as the circle shown but with a center at (-1.1).

To find : Which equation represents a circle ?

Solution :

The equation of a circle with center (h,k) and radius r is given by :

$(x-h)^2+(y-k)^2=r^2$

Here, we are given (h,k)=(-1,1)

and radius r=4 units

So, equation of circle will be :

$(x-(-1))^2+(y-1)^2=4^2$

$(x+1)^2+(y-1)^2=4^2$

or $(x+1)^2+(y-1)^2=16$

Therefore, the required equations of circle are

$(x+1)^2+(y-1)^2=4^2$ and $(x+1)^2+(y-1)^2=16$

Bogdan [553]

A confidence interval tells us how many percents we are confident about the range of a parameter. In this problem, <span>a 95% confidence interval for the mean number of hours spent relaxing or pursuing activities they enjoy was (1.38, 1.92). That means we're 95% confident that the Americans spend from 1.38 hours to 1.92 hours per day on average relaxing or pursuing activities they enjoy. In other words, 95% of the samples of the same size would have a mean number of hours relaxing or pursuing activities they enjoy between 1.38 to 1.92.</span>

lions [1.4K]

First of all, we know that a professional volleyball player can jump an average of 2.5 times higher than the average person which means that the player could jumps 2.5 times higher than the normal do. For example, if the normal people jumps 3 inches height, the professional player could jumps 2.5(3)=7.5 inches height. In this case, if an an average person can jump 2x inches high which leads to that the professional player could jumps 2.5(2x) higher. As a result, C is your final answer. Hope it help!

Find the value of X.

Kobotan [32]

Answer:

x = 18.46

Step-by-step explanation:

Find the last angle of the triangle.

180-90-72 = 18

The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

cos(b) = adj/hyp

CosB=a/c rewrite to get

6/CosB (72) = 19.41

Find the last side of the triangle using the Pythagorean theorem.

b=square root c^2 - a^2

b=square root 376.99 - 36

b= 18.46
