Hank estimated the width of the door to his classroom in feet. What is a reasonable estimate?

Answers

2 feet, because you aren’t going to have a regular classroom door be 9 feet wide, or have it be 1 foot wide because there are some non really disabled kids but they still have wheel chairs and stuff and it won’t be easy for them to get through a door that is 1 foot wide.

You are heating liquid in a chemistry lab. Four minutes ago, the temperature of the liquid was -4 degrees Celsius. Since then, it has been going up at a steady rate of 2 degrees per minute.
A. Write an equation that tells you the relationship between temperature and time at any given time. Designate the current time as 0.
B.Use your equation to predict the temperature of the liquid 15 minutes from now.

Answers

The rate of temperature rise is 2 degrees/minute.

The relation between temperature and time is of the form
y = 2x + b
where
x = time, minutes,
y = temperature, Celsius

When x = -4 min, y = - 4°C because the temperature was - 4°C 4 minutes ago. Currently, x = 0.
Therefore
-4 = 2(-4) + b
-4 = - 8 + b
4 = b

Part A
The relation is y = 2x + 4

Part B
When x = 15 (15 minutes from now), the temperature will be
y = 2(15) + 4 = 34°C

Answer: 34°C

Which letter would it be ??

Answers

It would be A.

C and D are the ones that are closest to incorrect.

If we say pi equals 3.14, and then multiply that by 3, we get 9.42.

9.42/2 = 4.71

So it has to be less then 4.71.

The square root of 21 is about 4.5.

So therefore, since pi + 1 is about 4.14, that is incorrect.

5 is larger then 4.71, so that is incorrect.

2[tex] \sqrt{6}[/tex] would then equal [tex] \sqrt{6} * \sqrt{4} [/tex], and then [tex] \sqrt{24} [/tex]

The square root of 24 is extremely close to the square root of 25, so it would be extremely close to 5, which would be incorrect.

So A would be the correct answer.

the nth term of a sequence is n+7 . what are the first 3 terms of the sequence

Answers

The answer is 34 hope this helps

Answer:

First 3 terms of the sequence are:

8,9,10

Step-by-step explanation:

The nth term of a sequence is n+7 .

We have to find the first three terms of the sequence

First term(n=1)   = 1+7 =8

Second term(n=2)   = 2+7 =9

Third term(n=3)      = 3+7 =10

Hence, first 3 terms of the sequence are:

8,9,10

We notice from the choices, that the problem is solved using the Pythagorean theorem somehow. How?

If ABC was a right triangle, the hypotenuse would be BC (the largest side), so the right angle would be A.

In that case we would have 54 squared (which equals 2916) equal to the sum of the squares of 22 and 51 (which equals 3085).

If the triangle was a right triangle, [tex]22^2+51^2[/tex] would be exactly equal to [tex]54^2[/tex], but it is larger. This means that a right angle is not large enough to 'enclose' [tex]22^2+51^2[/tex]. Thus angle A must be opened more that 90°.

Thus the answer is D:
 an obtuse triangle because  [tex]22^2+51^2>54^2[/tex]

There are 946 milliliters in a quart. There are 2 pints in a quart. How many milliliters are in a pint?

Answers

Answer:

Find out the  how many milliliters are in a pint .

To prove

As given

There are 946 milliliters in a quart.

There are 2 pints in a quart.

Thus

946 milliliters = 1quart =  2 pint

Than

946 milliliters =  2 pint

[tex]1\ pint = \frac{946}{2}\ millilitre[/tex]

1 pint = 473 millilitre

Therefore 473 milliliters are in a pint .

Answer:

How many 1760 got in 4710

Answers

4710 divided by 1760
The answer is 2.671

"The correct answer is 2.675.

To find out how many times 1760 is contained within 4710, we simply divide 4710 by 1760:

[tex]\[ \frac{4710}{1760} = 2.675 \][/tex]

This means that 1760 is contained exactly 2 times in 4710 with a remainder.

The decimal part (0.675) represents the fraction of the third 1760 that is not complete.

To express this as a fraction, we can write 0.675 as [tex]\(\frac{675}{1000}\),[/tex] which can be simplified by dividing both the numerator and the denominator by 125, giving us [tex]\(\frac{5.4}{8}\) or \(\frac{27}{40}\)[/tex] when expressed in lowest terms. Therefore, 4710 contains 2 complete sets of 1760 and a partial set equivalent to [tex]\(\frac{27}{40}\)[/tex] of 1760."

Recall:

Formula for volume of a cube is given as:

[tex]V = a^{3}[/tex]

where,

[tex]a =[/tex] length of each edge of the cube

[tex]V = 8[/tex]

Plug in the value into the formula to find a.

A game normally cost $53.00, but Isabel used a coupon and got the game for $37.10. The coupon was for what percent off.

Answers

We could use the numbers and the difference of the original cost - the end price in a equation.

53 × x/100 = 15.9

Cross multiply 100 × 15.9.

53x=1590

Divide both sides by 53.

x=30

The coupon was 30%
i think it is 30 because if you take 37.90 from 53.00 you get 15.90 and you calculate it like this:
                                          15.90×100≈1590÷53≈30%

given a right cone with radius r and slant height s, what does the formula pi rs represent

Answers

The formula of pi rs represents the formula to find the lateral surface area of a right cone.
Answer:

The formula πrs represent the lateral surface area of the cone.

Step-by-step explanation:

Lateral surface area--

The lateral surface area of a solid ( i.e. a three dimensional object) is the area of all the sides of the solid excluding the area of the base as well as top of the solid.

If r is the radius of the cone and s is the slant height of the cone then the lateral surface area of the cone is given by the formula:
