find the exact value of x. x=

Answer:135

Step-by-step explanation:

bcs 45x60 is 2700 ÷20= 135

Answer:

A.

Step-by-step explanation:

In the picture, the estimated slope goes down, so it has to be negative, eliminating 2, B and D

It isn't a gradual line, as 6x is, so that is eliminated.

When we look at the estimated line, we can count out on the grid 3 to the right and 4 down, doing that a few times.  If you then connect the dots, it will be a line probably very close to your estimate.

Answer: See explanation

Step-by-step explanation:

x - 4 = 17

Collect like terms to get the value of x

x = 17 + 4

x = 21

5x - 1 = 24

Collect like terms to get the value of x

5x = 24 + 1

5x = 25

Divide both side by 5

5x/5 = 25/5

x = 25/5

x = 5

answer is

-2

that is option b

Answer:

The distance from A to B is approximately 67.5 km

The bearing of B from A is approximately 86.89°

Step-by-step explanation:

i) The distances and the bearing of the motion of the ship is given as follows;

The distance the ship sails on a bearing of 048° = 30 km

The distance further the ship sails on a bearing of 110° = 42 km

From the drawing of the sailing of the ship created with Microsoft Visio, we have;

∠C = 48° + 70° = 118°

By cosine rule, we have;

c² = b² + a² - 2·b·a·cos(∠C)

From which we have;

c² = 30² + 48² - 2 × 30 × 48 × cos(118°) ≈ 4,556.07810082

c ≈ √(4,556.07810082) ≈ 67.5

The distance from A to B = c ≈ 67.5 km

ii) By sine rule, we have;

a/sin(A) = b/sin(B) = c/sin(C)

∴ sin(A) = a·sin(C)/c

Substituting the values of the variables gives;

sin(A) ≈ 48·sin(118°)/67.5

∠A ≈ arcsin(48·sin(118°)/67.5) ≈ 38.89°

Therefore, the bearing of B from A ≈ 48 + 38.89 = 86.89°.

Answer:

50 min

Step-by-step explanation:

Convert the hours and minutes to pure minutes. 1hr40min =60min +40min= 100min and 2.5hrs =2(60min)+30min=150min. Then subtract 150 from 100 to get 50 min longer.

Answer:

B. -1/12

Step-by-step explanation:

1/2 - 5/6 + 1/4 = -1/12

[tex] \frac{1}{2} - \frac{5}{6} = \frac{3}{6} - \frac{5}{6} = - \frac{2}{6} \\ \\ = - \frac{1}{3} + \frac{1}{4} = - \frac{4}{12} + \frac{3}{12} = - \frac{1}{12} [/tex]

Answer:

your answer will be B. y = | x+4 | - 2

Answer:

It's quite simple and there is no need for rounding, the answer should be 8ft

Step-by-step explanation:

Here's why,

This problem can be solved with the Pythagorean Theorem, since in draws a triangle.

The picture should explain it,  let's double check:

6^2+8^2=10^2

36+64=100

Looks like it checks out

Answer:

I agree, the answer should be 8ft

Answer:

Queremos hacer un problema donde tengamos adición (a + b) y substracción ( a - b) de números con signo, de tal forma que el resultado final sea 9.

El caso más simple para este tipo de problemas es algo como:

"Vas a un mercado a comprar un par de productos, el producto A cuesta $A, y el producto B cuesta $B, si solo tenés un billete de $C, cuanto será el vuelto?"

Bueno, el vuelto va a ser la diferencia entre lo que vos entregáis, $C, y el costo total de los productos que compras ($A + $B)

Entonces el vuelto va a ser:

vuelto = $C - ($A + $B)

Y queremos que el resultado de este problema sea 9, entonces podemos escribir:

vuelto = $9 = $C - ($A + $B)

Ahora debemos encontrar los valores de las incógnitas.

Podemos simplemente definir dos de ellas y encontrar la tercera, por ejemplo si $C = $20 y $A = $2, entonces:

$9 = $20 - ($2 + $B)

$9 = $20 - $2 -$B

$9 = $18 - $B

$9 - $18 = -$B

-$9 = -$B

Entonces $B será = $9.

Y el problema podría escribirse como:

"Vas a un mercado a comprar un par de productos, el producto A cuesta $2, y el producto B cuesta $9, si solo tenés un billete de $20, cuanto será el vuelto?"
