What changes about the numbers when you go from one to the next, and what stays the same? Here, it looks like you start with the number 44, but how do you change the number from one to the next?

Okay. For each of those numbers, you are adding another zero behind the number, which means you are multiplying by 10. 44 * 10 is 440. 440 * 10 is 4,400. 4,400 * 10 is 44,000. And so on. The rule is that you are multiplying by 10.

Answer:

42.3% or 11/26

Step-by-step explanation:

IN order to calculate the percentage of people that voted for Candidate A you just need to add up the number of votes for that candidate and then multiply it by 100 and divided by the total votes.

There were 26 voters, since there were 7 that didn´t vote for anyone, so we have that 11 voted for Candidate A:

$\frac{11}{x} =\frac{26}{100}\\ x= \frac{11*100}{26}\\ x=42.30$

So the percentage of voters that voted for candidate A was 42.3 percent.

A calculator is required to obtain the final answer on this question. A solid metal sphere at room temperature 20oC is dropped i

yKpoI14uk [10]

Answer:

T = 47.1875°C

Step-by-step explanation:

Given:

Surrounding temp, Ts = 100°C

Initial Temperature ,T0= 20°C

Increase in temperature = 15°C

Final temperature, T = 20 + 15 = 35°C

Time, t = 9 seconds

Let's take Newton's law of cooling:

$T - Ts = (T_0 - Ts)e^k^t$

We'll solve for k

$35 - 100 = (20 - 100)e^9^k$

$-65 = (-80)e^9^k$

Divide both sides by -5

$13 = (16)e^9^k$

$9k = ln (\frac{13}{16})$

$k = \frac{1}{9} ln (\frac{13}{16})$

$k = -0.02307104053$

Let's now find the temperature of the ball after 18 seconds in boiling water.

Use the Newton's equation again:

$T - Ts = (T_0 - Ts)e^k^t$

$T - 100 = (20 - 100)e^-0.0^2^3^0^7^1^0^4^0^5^3^*^1^8$

$T - 100 = (-80)e^-0.0^2^3^0^7^1^0^4^0^5^3^*^1^8$

$T - 100= -52.8125$

$T = 100 - 52.8125$

T = 47.1875°C

Temperature of the ball after 18 seconds in boiling water is 47.1875°C

PLEASE HELP WORTH 40 POINTS FOR WHOEVER ANSWERS CORRECTLY!!!! PLEASE HELP

ANTONII [103]

Answer:

x = 1 ⇔ y = -2.4

x = 2 ⇔ y = -1.8

x = 3 ⇔ y = -1.2

x = 4 ⇔ y = -0.6

Step-by-step explanation:

$3x-5y=15$

→ Rearrange to make y the subject

$-5y=-3x+15$

→ Multiply everything by -1

$5y=3x-15$

→ Divide everything by 5

$y=0.6x-3$

⇒ Substitute x = 1, 2, 3 and 4

$y=0.6x-3\\ y=(0.6*1)-3\\ y=0.6-3\\ y=-2.4\\(1,-2.4)$

$y=0.6x-3\\ y=(0.6*2)-3\\ y=1.2-3\\ y=-1.8\\(2,-1.8)$

$y=0.6x-3\\ y=(0.6*3)-3\\ y=1.8-3\\ y=-1.2\\(3,-1.2)$

$y=0.6x-3\\ y=(0.6*4)-3\\ y=2.4-3\\ y=-0.6\\(4,-0.6)$

Screen-printing a batch of shirts requires 3 minutes per shirt in addition to 13 minutes of initial set-up time. If it takes 616

krek1111 [17]

Answer: 201 shirts

Step-by-step explanation:

Let x= total shirts in the batch.

Total time taken for x shirts = Initial set-up time + (Time require per shirt) × (x)

$\Rightarrow\ 616= 13+3x\\\\\Rightarrow\ 3x=616-13\\\\\Rightarrow\ 3x= 603\\\\\Rightarrow\ x=\dfrac{603}{3}\\\\\Rightarrow\ x=201$

Hence, there are 201 shirts in the batch.
