Answer:
300G
Step-by-step explanation:
Here is the complete question
A wedding cake weighed 8kg. If 2/5th of its weight was flour, 5/16th was sugar,1/4th was cream and the rest were nuts, find the weight of nuts.
fraction of the cake that was nuts = 1 - (2/5 + 5/16 + 1/4)
1 - 
= 3/80
wight of nuts = 3/80 x 8 = 0.3 kg = 300g
Answer:
1. B
2.C
Step-by-step explanation:
A plot of land in the shape of a vertical ellipse. The equation of the ellipse is
If the foci are 8 feet from the center, then 
If the plot of land is 34 feet across the vertical axis, then 
Use formula 
(because ellipse is vertical, then b>a) to find a:
Then the plot of land is 2a=30 ft across the other axis.
If b>a, the eccentricity of the ellipse is
Answer:
y=-x+4
Step-by-step explanation:
Slope= Difference in y over difference in x position:
(2-8)/(2--4) --> -6/6 --> <u>-1</u>
The slope is -1
We can put what we have so far in slope intercept form: y=-1x+b
The y-intercept (also known as b) in this equation is 4
In slope-intercept form this line would be written as y=-1x+4,
or simply just y=-x+4
Q - 756 = 612 |add 756 to both sides
Q - 756 + 756 = 612 + 756
Q = 1368
6r+7=13+7r
Move 7r to the other side. Sign changes from +7r to -7r.
6r-7r+7=13+7r-7r
6r-7r+7=13
-r+7=13
Move +r to the other side. Sign changes from +7 to -7.
-r+7-7=13-7
-r=6
Multiply by -1 to get positive and for 6
-r(-1)=6(-1)
r=-6
Answer: r=-6
