There are 8 pints in one gallon. So, Avery would need 8 times 2 pints because she needs 2 gallons and there are 8 pints in every gallon.
8 x 2 = 16
Now subtract what she already has from the total she needs.
16 - 7 = 9
So, Avery needs 9 more pints of milk.
Answer: At 6% = $66,800
At 10% = $34,400
Step-by-step explanation:
Let S be his savings. He divided S into x that goes at 6% and y at 10%
As he put twiced as much at the lower-yielding one, x = 2y
Simple interest is given by: Amount x interest x time
This way I₁ = x . 0.06 . 1 = 0.06x
I₂ = y. 0.10 . 1 = 0.10y
As x = 2y, I₁ = = 0.06 . 2y = 0.12y
As we know that the annual interest was $7348
I₁ + I₂ = 7348
0.12y + 0.10y = 7348
0.22y = 7348
y = 7348/0.22
y = 33,400
As x = 2y, x = 2.33,400 = 66,800
This was he invested $33,400 and $66,800
Answer:
(15 – 22x)/4x(2x – 5)
Step-by-step explanation:
Let us take the numerator first:
(1/2x – 5) – (7/8x – 20) = (1/(2x – 5)) – (7/4(2x –5)) = (8x – 20 – 7(2x – 5))/(4(2x – 5)(2x – 5)
= (8x – 20 – 14x + 35)/4(2x – 5)² = (15 – 22x)/4(2x – 5)²
The denominator is: x/2x – 5
So we now have:
(15 – 22x)/4(2x – 5)² ÷ x/(2x – 5) = (15 – 22x)/4(2x – 5)² x (2x – 5) /X = (15 – 22x)/4x(2x – 5)
You find the area of each side and add it all together.
l=length h=height b=base
rectangle/square: 2(lxh)+2(hxb)+2(bxh)
Answer:
V = 10,240mm^3
Step-by-step explanation:
The volume of pyramid is given by the following formula:
(1)
b: base of the pyramid = (32mm)^2
h: height
Thus, it is necessary to find the value of h, by using the Pitagoras's theorem, one half of the base and the slant height (which forms a rectangle triangle with h):
by replacing in (1) you obtain:
hence, the volume is 10240mm^3
