What is the area of the rectangle

Answer:

La ordenada de Q es 7.

Step-by-step explanation:

La ecuación de una recta es:

y = a*x + b

donde a es la pendiente y b es la ordenada al origen.

Para este problema, sabemos que la pendiente es -2

Entonces:

a = -2

y = -2*x + b

También sabemos que esta recta pasa por el punto (5, -1)

Esto significa que cuando evaluamos la ecuación en x = 5, y toma el valor y = -1

Si reemplazamos esos valores en la ecuación, obtenemos:

-1 = -2*5 + b

-1 = -10 + b

-1 + 10 = b

9 = b

Entonces la ecuación de la recta es:

y = -2*x + 9

Sabemos que el punto Q está en la línea, y la abscisa de este punto es 1.

Entonces este punto es Q (1, k)

donde k es la ordenada de este punto.

Porque nuestra línea también pasa por este punto, podemos concluir que cuando x = 1, y = k

Reemplazando eso en la ecuación tenemos:

k = -2*1 + 9 = -2 + 9 = 7

k = 7

La ordenada de Q es 7.

Answer:

120 pounds

Step-by-step explanation:

65% of y= 78 pounds

[tex]\frac{65}{100}[/tex] × y = 78 pounds

65y = 78  × 100=7800

y= 7800/65= 120 pounds

Answer:

$3.56

Step-by-step explanation:

mark me brainlest please

Answer:

3.56

Step-by-step explanation:

First you wanna add the prices of all the food so its

Two Eggs= 3.38

Slice of Bacon= 1.49

Orange Juice= 1.09

Add All then you get 5.96 and add sales tax so you get 6.44

The Subtract 10.00 - 6.44 = A/3.56

Answer:

Abel gets 9 apples while Gino gets 6 apples.

Step-by-step explanation:

Total age = 20 (Abel's age =12 + Gino's age =8)

Abel's share =

[tex] \frac{12}{20} \times \frac{15}{1 } = 9[/tex]

Gino's share =

[tex] \frac{8}{20} \times \frac{15}{1} = 6[/tex]

Answer:

x < -2 (No, he shouldn't have reversed the inequality symbol).

Step-by-step explanation:

Given the algebraic expression;

19 - 2(1 - x) < 13

Opening up the bracket, we have;

19 + (-2*1) + (-2*-x) < 13

19 + (-2) + (2x) < 13

19 - 2 + 2x < 13

17 + 2x < 13

Rearranging the equation, we have;

2x < 13 - 17

2x < -4

Dividing both sides by 2, we have;

x < -2

Hence, your friend shouldn't have reversed the inequality symbol (sign).

Note: you should only flip the inequality symbol (sign) when you're dividing by a negative number such as -2.

For example, if we had re-arranged the equation as;

17 - 13 < -2x

4 < -2x

Dividing both sides by -2, we have;

4 > x

Answer:

m<1 = 48°

m<2 = 132°

m<3 = 132°

m<5 = 48°

Step-by-step explanation:

Given:

m<4 = 48°

Required:

m<1, m<2, m<3, and m<5

Solution:

m<1 = m<4 (alternate exterior angles are congruent)

m<1 = 48° (substitution)

m<2 = 180° - (m<1) (linear pair theorem)

m<2 = 180° - 48° (substitution)

m<2 = 132°

m<3 = m<2 (alternate interior angles are congruent)

m<3 = 132° (substitution)

m<5 = m<4 (corresponding angles are congruent)

m<5 = 48° (substitution)

Answer:

14√6.

Step-by-step explanation:

√54 = √9√6 = 3√6

√486 = √81 √6 = 9√6.

√24 = √4√6 = 2√6.

So √54 + √486 + √24

= 3√6 + 9√6 + 2√6

= 14√6.

Answer:

Step-by-step explanation:

Ice forms when the temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius). When you add salt, that temperature drops: A 10-percent salt solution freezes at 20 °F (-6 °C), and a 20-percent solution freezes at 2 °F (-16 °C). On a roadway, this means that if you sprinkle salt on the ice, you can melt it.

Answer:

375.66 cm²

Step-by-step explanation:

The two semicircles add to a full circle.

For the circle, d = 18 cm.

r = d/2 = 9 cm.

A = LW - πr²

A = (35 cm)(18 cm) - 3.14(9 cm)²

A = 375.66 cm²

9x = 81

x = 9

Then, multiply it by the biggest side which is 4:

9 x 4 = 36

Answer:

2 hours, 4 hours

Step-by-step explanation:

So lets go over what we know.

There are already 10 worksheets created.

Every 1 hour 3 more are made.

27 worksheets need to be made.

Ok, the first thing we can do is subtract the amount of worksheets needed by the amount we laready have:

27-10

=

17

Now, lets divide the amount of worksheets we still need, by how many we make each hour:

17/3

=

Well, 3 goes into 15, 5 times. Then 2 is left. So we know it takes 5 2/3 hours to create all 27 worksheets.

Looking at the answers, 6 hours, 8 hours, and 10 hours would work. However 2 hours and 4 hours would not work.

Hope this helps! ;)
