Tyler is building a fish tank in the shape of a sphere that has a diameter of 18 inches. Based on Tyler's research, it is recomm
Karo-lina-s [1.5K]

Answer: 4 fishes

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:  

Volume of a sphere = 4/3 x π x (diameter/2)^3  

Replacing with the values given:  

V = 4/3 x π x (18/2)^3  

v = 4/3 x π x (9)^3 = 3,053.63 in3  

Next, we have to divide the volume of the tank by 693 in3 (volume for each fish)

3,053.63/693 =4.40 = 4 fishes

Feel free to ask for more if needed or if you did not understand something.

Nikki drew a rectangle with a perimeter of 18 units on a coordinate grid. Two of the vertices were (4, –3) and (–1, –3). What co
Talja [164]

Answer:

There are two possible solutions for the other two vertices of the rectangle:

(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)

Step-by-step explanation:

Geometrically speaking, the perimeter of a rectangle (p) is:

p = 2\cdot b + 2\cdot h (1)

Where:

b - Base of the rectangle.

h - Height of the rectangle.

Let suppose that the base of the rectangle is the line segment between (4, -3) and (-1, -3). The length of the base is calculated by Pythagorean Theorem:

b = \sqrt{[(-1)-4]^{2}+[(-3)-(-3)]^{2}}

b = 5

If we know that p = 18 and b = 5, then the height of the rectangle is:

2\cdot h = p-2\cdot b

h = \frac{p-2\cdot b}{2}

h = \frac{p}{2}-b

h = 4

There are two possible solutions for the other two vertices of the rectangle:

(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)

In ΔUVW, the measure of ∠W=90°, the measure of ∠U=40°, and WU = 1.8 feet. Find the length of UV to the nearest tenth of a foot.
Dmitry_Shevchenko [17]

Answer: 2.3

Step-by-step explanation:

​

=

x

1.8

​

\cos 40=\frac{1.8}{x}

cos40=

x

1.8

​

x\cos 40=1.8

xcos40=1.8

Cross multiply.

\frac{x\cos 40}{\cos 40}=\frac{1.8}{\cos 40}

cos40

xcos40

​

=

cos40

1.8

​

Divide each side by cos 40.

x=\frac{1.8}{\cos 40}=2.3497\approx 2.3\text{ feet}

x=

cos40

1.8

​

=2.3497≈2.3 feet
