50% is equal to 5/10 so 5/10 were party cakes 1/5x2=2/10 so 2/10 were fruit cakes 5/10+2/10=7/10 so 10/10 which is 100% of all cakes 10/10-7/10=3/10 so 3/10 of the cakes were sponge cakes.
Answer:
24
Step-by-step explanation:
First we must recognize that this equation is a quadratic function, therefore we can use the quadratic equation and look only at the discriminate portion of that formula. However, before doing so we need to set up our equation by taking the 1 to the other side and so:
And we know that in general a quadratic function is such that:
And so our quadratic equation is:
But we only need to look at what's under the square root meaning:
This is our discriminant and since a=5, b=2 and c=-1 we have:
Answer:
Step-by-step explanation:
To solve this, we would use the formula for calculating simple interest which is:
Interest = PRT
Then, we will slot in the values given which will be:
84 = P × 3% × 7
84 = P × 0.03 × 7
84 = 0.21P
P = 84/0.21
P = $400
The Principal is $400
Answer:
0 to 10

Answer:
The angle of elevation is not properly represented
Step-by-step explanation:
Given
The question in the attachment;
Required
Determine the error
<em>See attachment for proper representation of the angle of elevation;</em>
<em>Solving further (From the Attachment)</em>
Multiply both sides by 3000
<em>The cliff is about 1212 feet high</em>
