Berries per ⅓ hour = 5¼ pounds =21/4

Per pound = $0.75

Berries to be picked in one hour = 21/4 × 3 = 15¾ pounds

Total money made in 1 hr= 15¾ × 0.75 = $11.81

Brady has a four square ball with a diameter of 12 inches when it is inflated what is the volume of the foursquare ball to the n

polet [3.4K]

Answer:

904.9 in^3

Step-by-step explanation:

Given data

We are told that the ball is 12 inches in diameter

R= diamter/2= 12/2= 6 in

The volume of a sphere is given as

V= 4/3πr^3

substitute

V= 4/3*3.142*6^3

V= 4/3*3.142*216

V=2714.688/3

V=904.9 in^3

Hence the volume is 904.9 in^3

Find the equation of the line, in slope intercept form that passes through the point (-6,5) and has slope 1/3

nexus9112 [7]

Answer:

y = x/3 + 7

Step-by-step explanation:

Use the equation: y - y1 = m(x - x1)

Plug in the given values into the equation:

y - 5 = (1/3)(x + 6)

Simplify the right side:

y - 5 = (x/3) + 2

Finally, add 5 to both sides:

y = x/3 + 7

Jack and Julio each improved their yards by planting daylilies and geraniums. They bought their supplies from the same store.

o-na [289]

Cost of one daylily is $2 and cost of one geranium is $4.

Step-by-step explanation:

Let,

Cost of one daylily = x

Cost of one geranium = y

According to given statement;

x+5y=22 Eqn 1

13x+y=30 Eqn 2

From Eqn 1;

x=22 - 5y

Putting this value of x in Eqn 2;

$13(22-5y)+y=30\\286-65y+y=30\\-64y=30-286\\-64y=-256$

Dividing both sides by -64

$\frac{-64y}{-64}=\frac{-256}{-64}\\y=4$

Putting y=4 in Eqn 1

$x+5(4)=22\\x+20=22\\x=22-20\\x=2$

Cost of one daylily is $2 and cost of one geranium is $4.
