The difference b/w the temperatures are

dt=43.5

This is further explained below.

<h3>What is temperature?</h3>

Generally, The term "temperature" refers to a physical quantity that indicates the degree to which an object or radiation is warm.

There are three different kinds of temperature scales: those, like the SI scale, that are defined in terms of the average temperature,

In conclusion, There are three different kinds of temperature scales: those, like the SI scale, that are defined in terms of the average temperature,

dt=19.7--23.8)

dt=43.5

Write the expression as either the sine, cosine, or tangent of a single angle. (2 points)

sattari [20]

Answer:

cos(π/3)cos(π/5) + sin(π/3)sin(π/5) = cos(2π/15)

Step-by-step explanation:

We will make use of trig identities to solve this. Here are some common trig identities.

Cos (A + B) = cosAcosB – sinAsinB

Cos (A – B) = cosAcosB + sinAsinB

Sin (A + B) = sinAcosB + sinBcosA

Sin (A – B) = sinAcosB – sinBcosA

Given cos(π/3)cos(π/5) + sin(π/3)sin(π/5) if we let A = π/3 and B = π/5, it reduces to

cosAcosB + sinAsinB and we know that

cosAcosB + sinAsinB = cos(A – B). Therefore,

cos(π/3)cos(π/5) + sin(π/3)sin(π/5) = cos(π/3 – π/5) = cos(2π/15)

Answer:

Step-by-step explanation:

B. For roses you could sell 84 bunches of 14 roses. For tulips, you could sell 70 bunches of 18 tulips, and for gerberas, you could sell 75 bunches of 18 gerberas.

C. well 8 dollars times 84 is $672. 11 times 70 equals $770, and 9 times 75 is $675. in total $2,117.

D. i - 1176 well to start we add up all the digits to see if its sum is divisible by 9. 1+1+7+6=15. 15 is not a multiple of 9 so its not divisible.

ii. 1260 well to see if 1260 is divisible by 8 is by taking the last 3 digits of the number and dividing it by 8. 260 divided by 8 equals 32.5. since 32.5 is a decimal and 8 can't go into 260 evenly 1260 is not divisible by 8.

Solve the following equation for z. 3yz+z=-2

vodomira [7]

Answer:

z=-2/3y+1

Step-by-step explanation:

Let's solve for z.

3yz+z=−2

Step 1: Factor out variable z.

z(3y+1)=−2

Step 2: Divide both sides by 3y+1.

z(3y+1)

3y+1

−2

3y+1
