Answer:

Gallons of punch used = 4.94 gallons

Step-by-step explanation:

Given that:

Liters of punch purchased = 25 liters

Liters of punch left over = 6 liters

Liters of punch used = 25 - 6 = 19 liters

According to the given statement;

1 liter = 0.26 gallons

19 liters = 0.26*19 gallons

19 liters = 4.94 gallons

Hence,

Gallons of punch used = 4.94 gallons

A line had a slope of -3 and a y-intercept if 3. what is the x-intercept of the line?

Helga [31]

Answer:

The answer to your question is 1

Step-by-step explanation:

Data

slope = m = -3

y-intercept = 3

Process

1.- Find the equation of the line in the slope-y-intercept form

y = mx + b

-Substitution

y = -3x + 3

2.- Find the x intercept

-If y = 0

0 = -3x + 3

-3 = -3x

-3/-3 = x

x = 1

-The x-intercept is 1

SOLUTION:

Case: Volume of Sphere

Method:

a) The volume of a sphere whose diameter, d= 28in

The radius,

r= 28/2

r= 14 in

The Volume, therefore:

$\begin{gathered} V=\frac{4}{3}\pi r^3 \\ V=\frac{4}{3}\pi\times14\times14\times14 \\ V=11494.04\text{ }cubic\text{ }inches \end{gathered}$

b) When half of the volume is used,

$\begin{gathered} V=\frac{1}{2}V_0 \\ V=\frac{1}{2}\times11494.04 \\ V=5747.02\text{ }cubic\text{ }inches \end{gathered}$

c) The radius of the halved volume

$\begin{gathered} V=\frac{4}{3}\pi r^3 \\ 5747.02=\frac{4}{3}\pi r^3 \\ r^3=\frac{3\times5747.02}{4\pi} \\ r^3=1372 \\ r=\sqrt[3]{1372} \\ r=11.11\text{ }inches \end{gathered}$

Final answer: (To 2 d.p)

a) 11494.04 cubic inches

b) 5747.02 cubic inches

c) 11.11 inches

HELPPPPP PLS AND THANK YOU

Answer:

First, you need to know the general volume formula of a prism

$V=Sh$

We can think of the bottom as a triangle facing us, the height is 12.5ft

Use the formula to get

V=Sh=（4×6×1/2）×12.5=150 ( $ft^{3}$ )
