Answer:
2:3
4:6
6:9
18:27
Step-by-step explanation:
The constant of proportionality is 2:3 for this problem. On the second one, I saw that there was a 6. 6 was double what 3 is so I multiplied 2 by 2 and got 4. I basically did that with the rest of the problems. like the second one there is a 6 on the left side, 6 is 3 times the amount of two so I multiplied 3 by 3 to get 9. On the last one, there was a 27 on the right side. 27 is 9 times greater than 3 so I multiplied 2 by 9 to get 18 on the left side. I hope I didn't make it too confusing.
Have a good day!

Francine rolls two 6-sided number cubes. What is the probability that she rolls a sum equal to 6? Use the diagram of the sample space to help you.
Answer:
5/36
Step-by-step explanation:
Basally you just need to see how many of the dices added up to 6. (6 and 1 don't count because that would add up to 7.)
Then find how many possibilities there were, in this case 36. 5 out of 36.
In other cases you would simplify if need be.

Reduce
only find the vertex and axis of symmetry
Answer:
vertex (5,2)
axis of symmetry: x=5
Step-by-step explanation:
vertex (h,k)
y = a(x - h)² + k
f(x)=(x-5)²+2 a = 1 h = 5 k = 2
vertex (5 , 2)
The axis of symmetry always passes through the vertex of the parabola. The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
x = 5

I have an easy and quick question. So the picture shows an answered question but how do you know to divide? I just don't understand.....
Answer:
Ok so u know to divide bc u r trying to isolate the variable and that means undoing the function in this case 0.6 is multiplied to p so u do the opposite which is division
tada
Hope this helps :)
Pls give brainliest XD :)
Answer: You're looking for what P represents
Step-by-step explanation:
You start off with the equation
then subtract the number without the variable in this case both sides. Leaving 4.5-4.5= 0 and 22.5-4.5= 18
You also need to have p as P=n (n= the number)
The equation 18/.6- 30, however you are looking for
0.6 divided by 18 which equal 0.33
so p=0.33

Step-by-step explanation:
First , Split the given figure into two parts i.e rectangle and a semi - circle.
\underline{ \underline{ \text{Given}}}: [/tex]
In rectangle :
Length ( L ) = 14 cmWidth ( W ) = 9 cmFinding the area of a rectangle :
[tex] \sf{Area \: of \: a \: rectangle = L \times W}[/tex]
⤷ [tex] \sf{14 \: cm \times 9 \: cm}[/tex]
⤷ [tex] \sf{126 \: {cm}}^{2} [/tex]
Area of a rectangle = 126 cm ²
Now , In circle :
Diameter ( d ) = 14 cm { Since In rectangle , length of both sides are equal }Radius ( r ) = [tex] \sf{ \frac{14 \: cm}{2} = 7 \: cm}[/tex][tex] \sf{Area \: of \: a \:semi - circle = \frac{1}{2} \pi \: {r}}^{2} [/tex]
⟷[tex] \sf{ \frac{1}{2} \times 3.14 \times {7}^{2} }[/tex]
⟷[tex] \sf{ \frac{1}{2} \times 3.14 \times 49}[/tex]
⟷[tex] \sf{ \frac{1}{2} \times 153.86 \: {cm}^{2} }[/tex]
⟷[tex] \sf{76.93 \: {cm}}^{2} [/tex]
Area of a semi - circle = 76.93 cm²
Now , We have :
Area of a rectangle ( A ) = 126 cm ²Area of a semi - circle ( a ) = 76.93 cm ²[tex] \sf{Area \: of \: a \: shaded \: part = A - a}[/tex]
⟷[tex] \sf{126 \: {cm}^{2} - 76.93\: {cm}}^{2} [/tex]
⟷[tex] \boxed{ \sf{49.07 \: {cm}^{2} }}[/tex]
[tex] \red{ \boxed{ \boxed{ \underline{ \sf{Our \: final \: answer : 49.07 \: {cm}^{2} }}}}}[/tex]
Hope I helped ! ♡
Have a wonderful day / night ツ

The mass of an average grain of table salt in a sample is about 3 x 10^-4 , and the mass of an average grain of rock salt in a sample is about 1.2 x 10^-2
Part A: Convert both masses to standard notation.
Part B: the mass of an average grain of rock salt is about 40 times the mass of an average grain of table salt. If you multiply the mass of table salt in standard notation by 40, what value do you get?
Part C: Is the value you got in part B equal to the mass of an average grain of rock salt? what does this mean?
Answer:
a. standard notation means in the number written in only number digits.
- to convert these multiply the two numbers given. FYI these are given in scientific notation, which is used so that numbers are easier to write.
remember: if the exponent is negative, you have move the decimal to the right. whereas, if the exponent is positive, you have to move the decimal to the left.
3 X 10^-4 --> move 4 places to the right.
answer - table salt: 0.0003
1.2 X 10^-2 --> move 2 places to the right.
answer - rock salt: 0.012
b. we know the standard notation of table salt is 0.003, so we simply multiply 40 by this.
answer - 0.0003 X 40 = 0.012
c. 0.012 = 0.012 (yes)
answer - yes the value i got in part B is equal to the mass of an average grain of rock salt. this shows that the mass of an average table salt is 1/40 times smaller than the mass of an average grain of rock salt.
- i am not sure about the "what does this mean" part. you can put whatever there but i put what i think it could be. i think it would be based on what notes you took on class.
Part(a),
The value of the masses in standard form is Rock salt: 0.012 and Table salt: 0.0003.
Part(b),
The multiplication is 0.012.
Part(c),
yielded a value equal to the mass of an average grain of rock salt. This demonstrates that the mass of an average grain of rock salt is 1/40 that of an average grain of table salt.
How to calculate the standard form?a. Standard notation means in the number written in only number digits. To convert these multiply the two numbers given. FYI these are given in scientific notation, which is used so that numbers are easier to write.
If the exponent is negative, you have moved the decimal to the right. whereas, if the exponent is positive, you have to move the decimal to the left.
3 X 10⁻⁴ --> move 4 places to the right.
Table salt: 0.0003
1.2 X 10⁻² --> move 2 places to the right.
Rock salt: 0.012
b. We know the standard notation of table salt is 0.003, so we simply multiply 40 by this.
0.0003 X 40 = 0.012
C. 0.012 = 0.012 (yes)
Yes, the value I got in part B is equal to the mass of an average grain of rock salt. this shows that the mass of an average table salt is 1/40 times smaller than the mass of an average grain of rock salt.
