elp pls I need elp pls pls

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!

Answer:

[tex]A=41.86 cm^{2}[/tex]

Step-by-step explanation:

The area of the shaded regions= [tex]\frac{0}{360}* \pi [(4)^{2}-(3)^{2}][/tex]

[tex]=\frac{120}{360} *3.14*(10)(4)\\[/tex]

[tex]=\frac{3.14*10*4}{3}[/tex]

[tex]A=41.86 cm^{2}[/tex]

Answer:

an extra 1/2 can

Step-by-step explanation:

if you change 1/3 into 2/6, you can see that he originally fed 2/6 of a can and now feeds 5/6 meaning that not he feeds an extra 3/6 which simplifies into 1/2

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.

Answer:

35

Step-by-step explanation:

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.

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.

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.
