round 40408 to the nearest 100

There are two statements here, showing quantities in real world which are additive inverse of each other :

2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.

here, we can depict going up as +2 miles and going down the trail as -2

4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.

And here we can assume going up the ground aa + 2000 ft and going down aa - 2000 ft .

Answer:

The options are (2) and (4).

Step-by-step explanation:

2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.

→ Up 2 mi (+2) and down 2 mi (-2).

4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.

→ Here they are, ascends 2000 ft (+2000) and descends 2000 ft (-2000).

Answer:

A = 16,800 feet

Step-by-step explanation:

a = (t-g)/- 0.0035

- 38.8 = - 0.0035a + 20

a = (-38.8 - 20) / -0.0035

a = ( - 58.8) / - 0.0035

a = 16,800 feet

Answer:

y =-5x-17

Step-by-step explanation:

Slode-intercept is

y = mx + c

The first step is to find the slope, that is the m

To do that, use this formula

Y2 - y1

------------

X2- x1

And u will get - 5

Now since u got m, u also actually have y and x, those are the coordinates they gave u. U can choose either one,(-3, - 2) or (-4, 3), cuz they would give u the same answrs

So let's say I chose (-4, 3)

So x = - 4, y = 3

y=mx +c

3= - 5(-4) +c

C = - 17

Therefore your end product will be

y = - 5x - 17

Answer:

3.2 cm

Step-by-step explanation:

800 m = 80000 cm (as every meter has 100 cm).

now, on the map that distance goes down 1/25000th of the original distance.

so,

80000 / 25000 = 80/25 = 16/5 = 3 1/5 = 3.2 cm

Se debe remover aproximadamente 140.848 centímetros cúbicos de madera para reducir las esferas a anillos con altura de 6 centímetros.

En esta cuestión se precisa calcular el volumen de la esfera y sustraer los volúmenes de dos casquetes esféricos de igual cantidad [1] y un cilindro recto respectivo a la operación de taladrado. [2] La cantidad de madera a remover queda definida por la siguiente expresión:

[tex]V = \frac{2\pi}{3}\cdot h^{2}\cdot (3\cdot R - h) + \pi\cdot r^{2}\cdot (2\cdot R-2\cdot h)[/tex] (1)

Donde:

Si sabemos que [tex]h = 1\,cm[/tex], [tex]R = 4\,cm[/tex] y [tex]r = 2.5\,cm[/tex], entonces la cantidad de madera a remover es:

[tex]V = \frac{2\pi}{3}\cdot (1\,cm)^{2}\cdot [3\cdot (4 \,cm) - 1\,cm] +\pi\cdot (2.5\,cm)^{2}\cdot [2\cdot (4\,cm)-2\cdot (1\,cm)][/tex]

[tex]V \approx 140.848\,cm^{3}[/tex]

Step-by-step explanation:

This is basically a calculator problem, though you can do it in your head. Follow the order of operations.

Here we have a problem of composition of functions.

Remember that:

(f ° g)(x) = f( g(x) )

Now we have the table:

x      | 1 2 3 4 5 6

f(x)   | 6 4 4 1 6 4

g(x)  | 5 5 2 1 4 3

Using the table, we want to find:

To read the table, for example for f(5) first you go to the "x" part of the table and find the 5.

Now you go to the f(x) table and see which is the value of f(5), in this case, we can see that f(5) = 6.

a)  f(g(1))

First, looking at the table, we can see that:

g(1) = 5

Then:

f(g(1)) = f(5)

Again, looking at the table we can see that f(5) = 6

Then we have:

f(g(1)) = 6

b) g(f(1))

Same approach as before:

f(1) = 6

then g(f(1)) = g(6)

And looking at the table, g(6) = 3

Then:  g(f(1)) = 3

c)  f(f(1))

f(1) = 6

f(f(1)) = f(6) = 4

f(f(1))  = 4

d)  g(g(1))

g(1) = 5

then:

g(g(1)) = g(5) = 4

g(g(1)) = 4

e) (gof)(3)

This is equal to:

(gof)(3) = g(f(3))

we know that f(3) = 4

then:

g(f(3)) = g(4) = 1

(gof)(3) = 1

f) (fog)(6) = f(g(6))

We can see that:

g(6) = 3

then:

f(g(6)) = f(3) = 4

Concluding:

(fog)(6) = 4

Step-by-step explanation:

Answer:

x > -1/3

Step-by-step explanation:

so first we are going to distribute the numbers outside of the parenthesis. which gives us the equation

18-9x-8+12x > 9

then we are going to add our like terms

so 12x + -9x gives us 3x

and 18 + -8 gives us 10

so it would gives us the equation 3x+10>9

we then subtract 10 from both sides to keep our numbers on the right which gives us

3x > -1

then we divide by 3 on both sides to get X

and we then get X > -1/3

Answer:

D

Step-by-step explanation:

Distribute 10 in the equation

10 x 3 + 10 x 4 = 70

Answer D. 10(3+4)

Answer:

180 cm²

Step-by-step explanation:

x = length

y = width

perimeter of a rectangle is the sum of all sides, so, 2×length plus 2×width.

x = 5y

72 = 2x + 2y

using the first equation as substitute in the second equation

72 = 2×(5y) + 2y = 10y + 2y = 12y

y = 6 cm

x = 5y = 5×6 = 30 cm

area = x × y = 30 × 6 = 180 cm²
