Answer:
Step-by-step explanation:
So basically you want to find the total percentage of cakes that weren't sponge cakes first.
You already have the 50% of party cakes. For the 1/5 percent of fruit cakes, you can multiply it by 20/20, to get 20/100, and then just take the 20 to get 20% that were fruit cakes.
Now you can just add the percentages together.
50% + 20% = 70%
So now you know 70% weren't sponge cakes, out of 100%.
So here you can just subtract 70% from 100% to figure out the remaining part of 100%, which must be sponge cakes.
100% - 70% = 30%
So 30% of the cakes were sponge cakes.
Answer:
21.6 m long
Step-by-step explanation:
To do this, we find the scale factor of the fencepost and the shadow.
3/1.8 = 1.66666667
So, we know that when we take the original length and multiply it, we get the new one, so:
1.666666667 * x = 36
x being the original length. Now, we divide both sides by 1.66666667 to get x alone and find the original length.
x = 21.6
To double check, we can take the scale factor and multiply it by the original to get the shadow.
21.6 * 1.666666667 = 36
It is correct
Answer: The y-intercept is 1
Step-by-step explanation:
y = mx + b m = slope, and b = y-intercept
plugging in the given values, we get
-9 = (-5/4)(8) + b
simplify to get
-9 = -10 + b
b = 1
y-intercept = 1
<span> there are six sides to a cube 1 2 3 4 5 6
the chances of getting less than or more than 3 are halved so for every
2 rolls there is 1 chance are you going to hit less than 3
so the answer is 2:1 </span>
