Answer:

Number 7 will appear 11 times in 1000

(hope this helps can I pls have brainlist (crown) ☺️)

Step-by-step explanation:

7 does not occur in 1000. So we have to count the number of times it appears between 1 and 999. Any number between 1 and 999 can be expressed in the form of xyz where 0 < x, y, z < 9. You have 1 × 9 × 9 = 81 such numbers.

If you can help would that would be amazing
shutvik [7]

Answer:

yes for the first one

because if you take number one for an example and use it for y

1^7*1^7*1^7=1 and 1^7*7*7=1

they both equal one

2.) \sqrt{x}

\sqrt[3]{x}\sqrt[6]{x}=\:x^{\frac{1}{3}}x^{\frac{1}{6}}=\:x^{\frac{1}{3}+\frac{1}{6}}

=x^{\frac{1}{3}+\frac{1}{6}}

join 1/3+1/6= 1/2

then you get the answer

\sqrt{x}

Step-by-step explanation:

Answer:

Question 3: b \geq 2

Question 4: r < -5

Question 5: y \leq -6

Step-by-step explanation:

Question 3:

b + 2 \geq 4\\b + 2  -2 \geq 4 - 2\\b \geq 2\\

Question 4:

13 > 18 + r\\13 - 18 > 18 -18 + r\\\\-5 > r\\ r < -5sign flips when r switches sides

Question 5:

3y \leq 2y - 6\\3y - 2y \leq 2y - 2y - 6\\\\y \leq - 6\\

Answer:

x ≥ 661.424°F or x[661.424,∞) and x ≤ - 27°F or x(-∞,-27]

Step-by-step explanation:

The melting point of the substance is - 32.78°C, then the melting point in °F is given by  

C = \frac{5}{9} (F - 32)

⇒ F - 32 = \frac{9}{5}C

⇒ F = 32 + \frac{9}{5} (-32.78)

⇒ F = - 27.004°F

Again, the boiling point of the substance is 349.68°C, hence, the boiling point in °F is  

F = 32 + \frac{9}{5} (349.68)

⇒ F = 661.424°F

Therefore, the range of temperature in °F for which the substance will not be in liquid state will be x ≥ 661.424°F or x[661.424,∞) and x ≤ - 27.004°F or x(-∞,-27.004], where x is the temperature of the substance in °F. (Answer)
