Answer: Each apple would cost $0.75.

Step-by-step explanation: If each juice is $1.75, then 2 of them equal $3.5. Subtract this from $9.50 to get 6 dollars remaining. We know now we can buy 8 apples from the remaining 6 dollars. So from this, divide 6 by 8, you get $0.75.

Dafna11 [192]

The customer gave me:
-- a ticket worth $5
-- a ticket worth $2
-- a bill worth $100
   Total. . . . . . .$107

I gave him:
-- some gas worth $17.01
-- a ticket worth    $ 5
-- two $1 tickets $ 2
-- a ticket worth    $ 3
Total. . . . . . . .$27.01

The total value of everything we trade has to be equal.

I owe him ( $107.00 - $27.01 ) =   $79.99 in change

Step-by-step explanation:

1) $(-4)^2{\cdot}(-4)$

We know that, $a^x{\cdot}a^y=a^{x+y}$

$(-4)^2{\cdot}(-4)=(-4)^{2+1}\\\\=(-4)^3\\\\=64$

2) $(-2)^5{\cdot} (-2)^3$

Again using above property,

$(-2)^5{\cdot} (-2)^3=(-2)^8\\\\=256$

3) $5^{-3}$

We know that,

$a^{-x}=\dfrac{1}{a^x}$

So,

$5^{-3}=\dfrac{1}{5^3}\\\\=\dfrac{1}{125}$

4) $2.5^2=2.5\times 2.5\\\\=6.25$

Hence, this is the required solution.

The roof of the building shown below has a span of 48 feet. The rafters upon which the roof is laid are 30 feet long, including

anyanavicka [17]

Solution :

Given :

Span of the roof = 48 feet

Length of the rafter = 30 feet (including the 4 feet overhung)

So, for the 30 feet long rafter, 26 feet will be rafter length from the high point of the roof to the edge of the roof and 4 feet will be the roof overhung.

Therefore, the horizontal span per rafter is

$=\frac{48}{2}$
