ΔT= 313.5k-240.3k = 73.2k.

Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature).Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius.

One unit increase in the Kelvin scale is the same as a one-degree increase in the Celsius scale. The only difference between these two scales is zero points of the thermometer.

ΔT= highest T° in k - lowest T° in k

40.5°c+273= 313.5k

-32.7°c+273= 240.3k

therefore the difference will be 73.2k

Kloe can make 4 flower arrangement

The number of flowers in each flower arrangement is 6 sun flowers, 4 roses and 12 white carnations.

The number of flower arrangements can be calculated as follows;

The first step is to calculate the HCF between the three numbers

24= 6 × 4

16= 4 × 4

48= 12 × 4

The HCF is 4

Hence the number of flower arrangement is 4  and the number of flowers in each flower arrangement is 6 sun flowers, 4 roses and 12 white carnations

The rocket moves really fast with high speed.

A projectile that receives thrust from a rocket engine is known as a rocket (from the Italian rocchetto, which means "bobbin/spool"). All of the propellant carried by the rocket is used to create the exhaust from its engine.

In actuality, the absence of an atmosphere in space allows rockets to operate more effectively.

Due to their ability to reach Earth's escape velocity, multistage rockets can reach any maximum altitude. Rockets may produce significant accelerations and are powerful, light, and lightweight when compared to airbreathing engines.

In order for rockets to go forward and function in the vacuum of space, their action-reaction engines quickly discharge exhaust in the opposite direction.

The measure of PQT = 142.

We know what ray QS bisects angle PQT. If you draw out angle PQT and ray QS you can see that angle PQS is congruent to angle SQT. Because of the definition of angle bisector. This also means that angle SQT is half of PQT. Because of this we know that we can set the measure of PQT equal to 2 times the measure of SQT.

So we can set up and solve the following equation as such:

2(8x-25) = 9x +34

16x - 50 = 9x +34

7x -50 = 34

7x = 84

x = 12

Again I this doesn't seem to be your final answer. To find the answer the measures of each angle you're going to want to plug 12 in for x for one of the angles. So I'll do it for angle SQT.

8(12) - 25

96 -25

71

So the measure of angle SQT should be 71. Therefore since QS bisects PQR, the measure of angle PQS should also be 71. The measure of PQT should be double that which makes it 142.

Answer:

The required number is 6. 6+6=12. 6×6=36.

Step-by-step explanation:

If we compare numbers -√7 and 3.12345 we find that 3.12345 is always greater than -√7.

What are inequalities ?

When two values are compared , an inequality represents whether one is greater than, less than, or not equal to the other.

It is given that there are two numbers which are  -√7 and 3.12345.

Let's compare the,.

We know that an irrational number is a number which can't be expressed other than using roots.

Here -√7 is an irrational number and if we represent that in decimal form then it can be written as :

-√7 = - 2.6467

Now , as this number is negative decimal number it is less than the other number given which is 3.12345 because 3.12345 is a positive decimal number. And we know that value of a positive number is always greater than a negative number.

i.e.,

3.1245 > -√7

Therefore , if we compare numbers -√7 and 3.12345 we find that 3.12345 is always greater than -√7.

Step-by-step explanation:

The exponential function that would be a good model for the bouncing ball is [ 60 * [tex]0.6^{x}[/tex]] .

Given : height = 5 feet

            rebound on first bounce = 35 inches

            rebound on second bounce = 21.5 inches

To find :  exponential function that would be a good model for the                      bouncing ball

Calculation :

at x = 0

ht. = 5 feet = 60 inches

at x = 1

ht. = 35 inches

at x = 2

ht. = 21.5 inches

( 21. 5 / 35 ) * 100 = 60 % approx.

Since , the ht. rebounded is about 60% of the previous ht. rebounded , the exponential function that would be used would be of the form y = a * ( [tex]b^{x}[/tex] ) .

We need to know about logarithm to solve this problem. The greatest integer that is less than log 0.08 is -2.

Logarithm is the exponent which is raised to a base to get a certain number. There are a few rules of logarithm, log a + log b can be written as log ab, log a- log b can be written as log a/b, when the number for which the logarithm is calculated is raised to a power, then the power can be directly multiplied to the log itself. Logarithms when written as log has a base of 10 and the logarithm of a number same as its base is always 1, log of 1 is zero.

log 0.08= log 8/100= log 8- log 100 = [tex]log 2^{3} -log 10^{2}[/tex]

The missing value of the inverse variation is 8

The inverse variation property states that , whenever the product of values of two quantities is a constant value then there is opposite variation between these two corresponding values. Or we can also say that if the productive nature of two corresponding values is constant, then one quantity is inversely varies with second quantity.

Let say if x and y are two values and k is a constant value, then

According to inverse variation

k = xy or y = k/x

In the given question,

Take the order pair (4,6)

As it is an inverse variation, we can substitute it

y=k/x  

6=k/4

K=24

Answer:

The record time that was achieved in 1970 was 5.78 seconds.

Step-by-step explanation:

It is given that the first one-mile speed record was made by Henry Ford in 1904 when he drove the mile in 39.40 seconds.

It is further stated that this time was 33.62 s slower than the record achieved in 1970.

Now, let us consider the first statement;

Henry Ford covered one mile in time (1904) = 39.40 sec

Now, let us consider the second statement given;

Time taken by Henry Ford (1940) was slower than the time someone else achieved in one miles by = 33.62 sec

So, to calculate the time taken in 1970;

=> 39.40 - 33.62 sec

=> 5.78 sec

Therefore, the record time that was achieved in 1970 was 5.78 seconds.
