Answer:

table 4

Step-by-step explanation:

for it to be a function it has to have different domains, so you just have to find the table with different first numbers.

Express the edge length of a cube as a function of the cube's diagonal length d. Then express the surface area & volume of t

Lorico [155]

D = sqrt(3s^2) where s is the length of the side. Solving for s,

3s^2 = d^2 iff 
s^2 = d^2 / 3 iff 
s = sqrt(d^2 / 3) 
= d / sqrt(3) or d sqrt(3) / 3 

Surface area of the cube = 6 s^2. Thus, 
A = 6 (d / sqrt(3))^2 
= 6d^2 / 3 
= 2d^2 

Volume = s^3. Thus, 
V = (d / sqrt(3))^3 
= d^3 / 3sqrt(3) 
= d^3 sqrt(3) / 9

Your friend's swimming pool is in the shape of a rectangular prism, with a length of 25 feet, a width of 8 feet, and a height of

RUDIKE [14]

Answer:

Part a) $V=1,000\ ft^{3}$

Part b) $h=5\ ft$

Part c) $=718\ gal$

Step-by-step explanation:

Part a) What is the volume of your friend's swimming pool?

we know that

The volume of a rectangular prism is equal to

$V=LWH$

substitute the values

$V=(25)(8)(5)=1,000\ ft^{3}$

Part b) Your swimming pool is in the shape of a cylinder with a diameter of 16 feet and has the same volume as your friend's pool. What is the height of your pool?

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

we have

$V=1,000\ ft^{3}$

$r=16/2=8\ ft$ ----> the radius is half the diameter

substitute and solve for h

$1,000=\pi (8)^{2} h$

$h=1,000/(64 \pi)$

$h=1,000/(64*3.14)=5\ ft$

Part c) While you were on vacation, 6 inches of water evaporated from your pool. About how many gallons of water evaporated from your pool?

remember that

$1\ ft=12\ in$

$6\ in=6/12=0.5\ ft$

Find the volume of water for $h=5-0.5=4.5\ ft$

$V=(3.14)(8)^{2}(4.5)=904.32\ ft^{3}$

the volume of water evaporated is equal to

$1,000\ ft^{3}-904.32\ ft^{3}=95.68\ ft^{3}$

convert to gallons

remember that

$1\ ft^{3}=7.5\ gal$

$95.68\ ft^{3}=95.68*7.5=718\ gal$

Answer:

La respuesta correcta es la opción d) 5 a 1.

Step-by-step explanation:

Para calcular la relación entre los ingresos de Mary en 2019 ( $I_{2019}$ ) con respecto a sus ingresos en 2018 ( $I_{2018}$ ), partimos de que los ingresos de Mary en 2019 fueron un 20% mayores que sus ingresos en 2018:

$I_{2019} = 20\% \: I_{2018}$

$I_{2019} = \frac{20}{100}I_{2018}$

$\frac{100}{20}I_{2019} = I_{2018}$

$5I_{2019} = I_{2018}$

Entonces, la relación entre los ingresos de Mary en 2019 es 5 veces los ingresos de Mary en 2018. Por lo tanto, la respuesta correcta es la opción d) 5 a 1.

Noah drew 22 hearts and 76 circles. What is the ratio of circles to all the shapes?

dimulka [17.4K]

You would make a fraction with circles on the top which would be 76. Then you would add 22 to 76 and get 97 because that is the number of all of the shapes. That would mean your fraction would be 76/97. If u want to simplify that is up to you.
