Answer:
a) 6 cups
Step-by-step explanation:
We can use a ratio for this:
sugar : flour
2 : 3
x : 9
2 3
--- = ---
x 9
Cross multiply:
2 (9) = 3x
18 = 3x
6 = x
x = 6
To double-check, you can plug the value back into the ratio and make them fractions, then simplify to see if it gets the original amount. Here's what I'm talking about:
2 : 3
x : 9 ======> 6 : 9
[tex]\frac{6}{9} \frac{/3}{/3} = \frac{2}{3}[/tex]
Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 20)(0,20) and (6, 1280)(6,1280).
Answer:
[tex]y=20(2)^x[/tex]
Step-by-step explanation:
We want to write an exponential function that goes through the points (0, 20) and (6, 1280).
The standard exponential function is given by:
[tex]y=ab^x[/tex]
The point (0, 20) tells us that y = 20 when x = 0. Hence:
[tex]20=a(b)^0[/tex]
Simplify:
[tex]20=a(1)\Rightarrow a=20[/tex]
So, our exponential function is now:
[tex]y=20(b)^x[/tex]
Next, the point (6, 1280) tells us that y = 1280 when x = 6. Thus:
[tex]1280=20(b)^6[/tex]
Solve for b. Divide both sides by 20:
[tex]64=b^6[/tex]
Therefore:
[tex]b=\sqrt[6]{64}=2[/tex]
Hence, our function is:
[tex]y=20(2)^x[/tex]

Can Someone Help? I'll Give Points And I'll Follow You! :)
Answer:
I believe that it is A, C and G
Step-by-step explanation:
for A(7×2=14)+4=18 is equivalent to (3×2=6)+5+(4×2=8)-1=18
For C it is right because with the values being the same at x value at first the second equation would have one extra but it does subtract that.
For G check c :)

1. What is the measure of angle B04?
2. What is the measure of angie BDA?
3. What is the measure of angle BCA?
Using the inscribed angle theorems, the measure of the indicated angles are:
1. m∠BOA = 30°
2. m∠BDA = 15°
3. m∠BCA = 15°
What is the Inscribed Angle Theorems?Based on the inscribed angle theorems, the following relationships are established:
Inscribed angle = 2(measure of intersected arc)Central angle = measure of intersected arcGiven:
Intercepted arc BA = 30°
1. ∠BOA is central angle
Thus:
m∠BOA = 30° (inscribed angle theorems)
2. ∠BDA is inscribed angle.
m∠BDA = 1/2(30) = 15° (inscribed angle theorems)
3. m∠BCA = m∠BDA = 15° (inscribed angle theorems)

Answer:
x=4
Step-by-step explanation:
1. 2x+4=12
2. 2x+4-4=12-4
3. 2x=8
4. 2x/2=8/2
5. x=4
Answer:
x=4
Step-by-step explanation:
2x+4=12
Step 1: subtract both sides by 4
4-4=0 and 12-4=8
Now you are left with 2x=8
Step 2: divide 2 on both sides
2/2=1x and 8/2=4
Therefore, x=4
