The gasoline gauge on a van initially read one third

3/4 - 1/3 = 9/12 - 4/12 = 5/12

(5/12) / 10 = 1 / x
5/12x = 10
x = 10* 12/5
x = 120/5 = 24 gallons...so when full, the tank holds 24 gallons

so if it is already 3/4 full, then u just need 1/4 to fill
1/4(24) = 24/4 = 6......so u would need 6 more gallons to fill the tank up to full capacity.

Rachel is a stunt driver. One time, during a gig where she escaped from a building about to explode(!), she drove to get to the

Answer:

$D(t)=-24t+166$

Step-by-step explanation:

Let

D(t) = the distance to the safe zone (measured in meters)

t = time (measured in seconds)

Given:

Rachel's rate = 24 meters per second

At $t_1=4$ seconds $D(t_1)=70$ meters

Find: D(t)

Rachel's rate is the slope of the function D(t). Since the distance is decreasing when the time is increasing, the slope must be negative.

Hence, the function expression is

$D(t)=-24t+b$

To find b, substitute $t_1=4$ and $D(t_1)=70:$

$70=-24\cdot 4+b\\ \\70=-96+b\\ \\b=70+96\\ \\b=166$

So,

$D(t)=-24t+166$

the area of a triangle is 96 2. the height of the triangle is 8 inches. find the perimeter of the triangle if each side of the t

Anastasy [175]

Area = 1/2 bh
96 = 1/2 x b x 8 = 4b
b = 96/4 = 24 inches

Perimeter = 3b [since the other sides are equal to the base]

P = 3 x 24 = 72 inches.

Zoe has a board 5 1/4 long. she cut off a piece. now the board is 3 5/6 feet long. how long was the piece she cut off

KatRina [158]

The piece Zoe cut off would be 1 and 5/12 ft long.
5 and 1/4 - 3 and 5/6
The least common denominator is 24.
5 and 6/24 - 3 and 20/24
5 and 6/24 becomes 4 and 30/24
4 and 30/24 - 3 and 20/24 = 1 and 10/24
1 and 10/24 can be simplified to 1 and 5/12.
