Answer:
D. 7.5 inches
Step-by-step explanation:
So, we can find the ratio of the big triangle to the small one by dividing the values of the hypotenuse.
So, 18/6 = 3
Big:small = 3:1
So, using this we can make an equation to find AD.
Let's say ED=x.
AD is basically ED (x) + AE (5).
Since ED is part of the small triangle, and AD is part of the big one, we can use the 3:1 ratio from above.
So, 
=3.
Multiply both sides by x, getting x+5 = 3x.
Subtract the x: -x -x
And you get 5=2x, giving you 2.5 = x.
However, we're not done yet, as 2.5 is the value of ED, but we need AD.
Remember, AD is = ED + AE.
So, AD = 2.5 + 5.
Finally, AD = 7.5
Answer - 13.098 gm
Description -
Dear student,
As we know 
⇒ Mass = Density * Volume
so multiplying given Volume with the Density of gold ,we can calculate the mass of the gold . Density of gold at room temp. is 19.32 grams per cubic centimeter.
so mass of the sliver of gold = 19.32 * 0.678 = 13.098 (ans)
Answer:
7 units
Step-by-step explanation:
Given that :
house is at (−4, 10). Her school is at (−4, 3)
House location = (-4, 10)
School location = (-4, 3)
Distance from house to school (d) :
Distance between two points :
x = sqrt[(x2 - x1)^2 + (y2 - y1)^2]
x1 = - 4 ; y1 = 10 ; x2 = - 4 ; y2 = 3
d = sqrt[(-4 - (-4))^2 + (3 - 10)^2]
d = sqrt[(-4 + 4)^2 + (-7)^2]
d = sqrt(0 + (-7)^2)
d = sqrt(49)
d = 7 units
Since 3cups = 9cups ... and they are asking how much water would go in 2cups of sugar .. then the answer would be ..
6cups of water
because you cross multiply.
