27 and 36


12 is too short to be multiplied by 9, 21 can be multiplied by 3 but not 9 again, 3 can’t go into 45. Which leaves 27 and 36. 3 times 9 equals 27. 3 times 12 equals 36, 9 times 4 equals 36.

In a fireplace, about 3/4 of an 18 inch log will burn in 1/3 of an hour. How many hours will it take to burn 2 1/2 logs
Karo-lina-s [1.5K]
\bf \begin{array}{ccll}
\stackrel{burned}{log}&\stackrel{time}{hr}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{3}{4}&\frac{1}{3}\\\\
2\frac{1}{2}&h
\end{array}\implies \cfrac{\frac{3}{4}}{2\frac{1}{2}}=\cfrac{\frac{1}{3}}{h}\implies \cfrac{\frac{3}{4}}{\frac{2\cdot 2+1}{2}}=\cfrac{\frac{1}{3}}{\frac{h}{1}}

\bf \cfrac{\frac{3}{4}}{\frac{5}{2}}=\cfrac{1}{3}\cdot \cfrac{1}{h}\implies \cfrac{3}{4}\cdot \cfrac{2}{5}=\cfrac{1}{3h}\implies \cfrac{6}{20}=\cfrac{1}{3h}\implies 6\cdot 3h=20\cdot 1
\\\\\\
18h=20\implies h=\cfrac{20}{18}\implies h=\cfrac{10}{9}\implies h=1\frac{1}{9}

about 1 hour and 6 minutes with 36 seconds.

2- 10+ x = 6 -8 + 12<br> Please answer ASAP :)
Arisa [49]

Answer: X=18

Step by Step:

2−10+x=6−8+12

Step 1: Simplify both sides of the equation.

2−10+x=6−8+12

2+−10+x=6+−8+12

(x)+(2+−10)=(6+−8+12)(Combine Like Terms)

x+−8=10

x−8=10

Step 2: Add 8 to both sides.

x−8+8=10+8

x=18

Given the parent function f(x)=x^2 in red, write the equation for the transformed function g(x) in green.
Nataly_w [17]

Answer:

g(x) = 2x² + 1

Step-by-step explanation:

The parabola got thinner, so to show that, you put a 2 <u><em>before</em></u> x²<em> </em>to show that the graph was <em>dilated </em>(or thinned) by a factor of <em>2 </em>(Note: this number can also be <em>negative</em>, so if the dilation factor is negative, it's okay). Since the parabola shifts up by <em>1</em>, you then add + 1<em> </em><em><u>after</u></em> x² to show the positive upward shift.

Your full equation would look like this: g(x) = 2x² + 1

Dilation: this just means that every point on the parent function was double (or whatever the factor is) in the transformed function.
