The maximum walking speed S, in feet per second of an animal can be modeled by the equation S= √gL , where g=32ft/sec

Answers

Answer:

1.41

Step-by-step explanation:

The maximum walking speed S, in feet per second, of an animal can be modeled by the equation S= √(gL), where g = 32ft/sec² and L is the length, in feet, of the animal's leg. To the nearest hundredth, how many times greater is the maximum walking speed of a giraffe with a leg of 6 feet than a hippopotamus with a leg of 3 feet?

Step 1: Calculate the maximum walking speed of a giraffe

The leg of a giraffe measures L = 6 ft.

Sg= √(g × Lg)

Sg= √(32 ft/s² × 6 ft) = 13.86 ft/s

Step 2: Calculate the maximum walking speed of a hippopotamus

The leg of a hippopotamus measures L = 3 ft.

Sh= √(g × Lh)

Sh= √(32 ft/s² × 3 ft) = 9.80 ft/s

Step 3: Determine how many times greater is the maximum walking speed of a giraffe than a hippopotamus

We will make the ratio Sg/Sh

Sg/Sh = (13.86 ft/s)/(9.80 ft/s) = 1.41

The maximum walking speed of a giraffe is 1.41 times greater than the maximum walking speed of a hippopotamus.

What is the ratio?

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

The leg of a giraffe measures L = 6 ft.

S(g)= √(g×L)

S(g) = √(32 ft/s² × 6 ft)

S(g) = 13.86 ft/s

The maximum walking speed of a hippopotamus:

The leg of a hippopotamus measures L = 3 ft.

S(h)= √(g×L)

S(h) = √(32 ft/s² × 3 ft)

S(h) = 9.80 ft/s

The ratio S(g) to S(h)

S(g)/S(h) = 13.86/9.80 = 1.41

S(g) = 1.41S(h)

Thus, the maximum walking speed of a giraffe is 1.41 times greater than the maximum walking speed of a hippopotamus.

Evaluate 3xy + b if x = -4 ,y = 2 , and b = 5

Answers

Answer:

-19

Step-by-step explanation:

ok so since they give you all the variables you can substitute their values

for example instead of 3xy you can write 3*(-4)y

so that is the basic idea for this problem

after substituting, the new equation is 3*(-4)*2 +5

i plan on using order of operations, or PEMDAS

3*(-4)=(-12)

(-12)*2=(-24)

-24+5=-19

so the answer is -19

hope this helps!

Pizza Palace's largest pizza box has side lengths of 18 inches. A customer wants to special order a pizza
with an area of 300 square inches. Will the pizza fit in one of Pizza Palace's pizza boxes?

Answers

Answer:

No,the pizza will not fit in the box

Step-by-step explanation:

Since the diameter of the pizza is 19.6 inches which is greater that the side length of the box, the pizza is longer than the side lengths of the box

to get the diameter of the pizza,Since the pizza is circular in shapeArea of a circle = π r²where r is the radius and the area is 300 inch²

300 = 3.142 × r²

[tex] {r}^{2} \: = \: \frac{300}{3.142} \\ {r}^{2} = 95.48 \\ r \: = \sqrt{95.48} \\ r \: = \: 9.8 \: inches[/tex]But diameter is two times the radius So.....diameter = 2r Diameter of the pizza = 2 × 9.8Diameter of the pizza = 19.6 inches

Top box equals 10

(5x2)

Middle box equals 15

(5-2+2) x 3

Bottom box equals 10

(5x2)

Answer:

35 in sq.

Step-by-step explanation:

Find the area of each rectangle and add them together.

Area of a rectangle = length*height

Top rectangle: This one is easy. Length=2 Width=5

5*2=10

Middle rectangle: There's a missing segment in the width but we can find it. Notice the bottom rectangle's width includes the missing segment + 2 (look at the top rectangle). 5-2 is 3. Add the 2 of the known segment to the 3 of the previously unknown segment.

Length=3 Width=5

5*3=15

Bottom rectangle: This one is also easy. Length=2 Width=5

2*5=10

10+15+10=35 in sq.

¿es cierto que si se suman los resultados de la tabla del con los de la tabla del 5 se obtienen los resultados del 7 ¿porque

Answers

Answer:

Efectivamente, si se suman los resultados de la tabla del 2 con los de la tabla del 5 se obtienen los resultados de la tabla del 7.

Step-by-step explanation:

Esto es así porque 7 puede formarse a través de diversas sumas (7+0, 6+1, 5+2 o 4+3). Por ende, en el caso de las tablas de multiplicaciones, decir, por ejemplo, 7 x 3, es igual a decir 5 x 3 + 2 x3, dado que 5 + 2 es igual a 7.

Entonces, siguiendo el ejemplo, dado que 7 x 3 es igual a 21, la suma de 5 x 3 igual a 15 y 2 x 3 igual a 6 es 21 (15 + 6), con lo cual la afirmación es correcta.
