Answer:

In bold.

Step-by-step explanation:

1.

There are a total of 11 letters in the bag including 4 vowels, 7 consonants.

The letter m appears twice in mathematics.

(a) Probability(getting a vowel) = 4/11.

(b) Probability(getting a consonant) = 7/11.

(c) Probability(getting a letter m) = 2/11.

2.

Let the number be n, then:

8 + 2n = 40

2n = 32

n = 16.

Answer:

1) 30%, 50%, 10%

2) x = 24

Step-by-step explanation:

<em>Hey there!</em>

<em />

1) "MATHMATICS"

a) Vowels - a, e, i, o, u

This is 3/10 of the letters meaning pulling a vowel is 30%.

b) Constants - B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, X, Z

Well there are 5 constants in mathematics so the percent is 50%.

c) Letter "m"

The letter m is 1/10 meaning pulling the letter m is a 10%.

2) 8 added to twice a number gives 40. Find the number

Well lets set u an equation,

8 + x + 8 = 40

16 + x = 40

-16

x = 24

<em>Hope this helps :)</em>

Ayudaaaaa porfavor Convertir las unidades de medida 8 000 m = _______ km 4 000 g = _______ kg 3 000 m = ________ km 7 m = ______

jek_recluse [69]

Answer:

a) $x = 8\,km$ , b) $x = 4\,kg$ , c) $x = 3\,km$ , d) $x = 700\,cm$ , e) $x = 3\,cm$ , f) $x = 100\,mm$ , g) $x = 7\,mm$ , h) $x = 10000\,mL$ , i) $x = 8\,m$ , j) $x = 6000\,g$

Step-by-step explanation:

a) 1 kilómetro equivale a 1000 metros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

$x = 8000\,m \times \frac{1\,km}{1000\,m}$

$x = 8\,km$

b) 1 kilogramo equivale a 1000 gramos, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

$x = 4000\,g \times \frac{1\,kg}{1000\,g}$

$x = 4\,kg$

c) 1 kilómetro equivale a 1000 metros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

$x = 3000\,m \times \frac{1\,km}{1000\,m}$

$x = 3\,km$

d) 1 metro equivale a 100 centímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

$x = 7\,m \times \frac{100\,cm}{1\,m}$

$x = 700\,cm$

e) 1 centímetro equivale a 10 milímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

$x = 30\,mm \times \frac{1\,cm}{10\,mm}$

$x = 3\,cm$

f) 1 centímetro equivale a 10 milímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

$x = 10\,cm \times \frac{10\,mm}{1\,cm}$

$x = 100\,mm$

g) 1 centímetro equivale a 10 milímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

$x = 70\,mm\times \frac{1\,cm}{10\,mm}$

$x = 7\,mm$

h) 1 litro equivale a 1000 mililitros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

$x = 10\,L\times \frac{1000\,mL}{1\,L}$

$x = 10000\,mL$

i) 1 metro equivale a 100 centímetros, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

$x = 800\,cm \times \frac{1\,m}{100\,cm}$

$x = 8\,m$

j) 1 kilogramo equivale a 1000 gramos, entonces obtenemos el valor requerido mediante la siguiente regla de tres simple:

$x = 6\,kg\times \frac{1000\,g}{1\,kg}$

$x = 6000\,g$

Given the slope and one point on the line:

statuscvo [17]

Answer:

y= -2x + 11

Step-by-step explanation:

standard form for lines is y=mx+b

m is the slope and b is the y intercept

we already know that m is -2, so we just need to figure out the intercept.

the point given is (7,-3)

points are written as (x,y) so we can plug it into the equation with 7 for the x and -3 for y

-3 = -2 (7) + b

-3 = -14 + b

11 = b

so the equation is y=-2x+11

Write an equation in point-slope form for the line that passes through the point with the given slope. (-5, -8), m = -2 *

chubhunter [2.5K]

Answer:

$y+8=-2(x+5)$

Step-by-step explanation:

To create the equation using the point slope form which is $y-y_{1} =m(x-x_{1} )$ substitute the terms with the points given above.

$y-(-8)=-2(x-(-5))\\$

After plugging it in, then you simplify the terms which gives you...

$y+8=-2(x+5)$
