Answer 1

Answer:

7. A=48

8.B=30

9. C=188

10. D=18

11. X=32

12.Y=40

Step-by-step explanation:

Answer 2

Answer:

7. [tex]a=48[/tex]

8. [tex]b=30[/tex]

9. [tex]c = 188[/tex]

10. [tex]d = 18[/tex]

11. [tex]x = 32[/tex]

12. [tex]y = 40[/tex]

Step-by-step explanation:

Let's do something called cross-multiplication. It's exactly what it sounds like, we multiply the top number with the denominator across the multiplication.

[tex]\frac{33}{a} = \frac{11}{16}[/tex]

[tex]11 a = 33(16)[/tex]

[tex]11a = 528[/tex]

Now we can simplify.

[tex]a=48[/tex]

So we got the answer for the first one. We can keep doing the same thing for the others.

A line passes through the origin and has a slope of 2/3​

Answers

Answer:

y=2/3x

Step-by-step explanation:

the origin is the point (0,0) and the given slope is 2/3

the equation for slope-intercept form is y=mx+b, where m is the slope and b is the y intercept

the slope is given, meanwhile, the y intercept is the point where the line passes through the y axis, and the x value is 0.

In this question, we actually have the y intercept given, which is (0,0)

we can put it all together then:

y=2/3x+0

or

y=2/3x

Se ha decidido repoblar con 150 000 árboles una zona asolada por un incencio. Se quieren plantar los árboles formando un cuadrado con el mismo número de árboles y la misma separación entre ellos. ¿Cuántos árboles se podrán plantar para formar el cuadrado más grande posible?

Answers

Responder :

Se plantarán 149769 árboles

Explicación paso a paso:

Dado que:

Número de árboles a plantar = 150.000

Los árboles deben disponerse para formar un cuadrado;

La cantidad de árboles que se pueden plantar para hacer el cuadrado más grande posible:

Área de un cuadrado = s²

Dónde; s = Longitud de cualquier lado; ya que todos los lados son iguales.

El mayor número de árboles que se pueden plantar es el cuadrado perfecto más alto hasta 150.000.

Esto se puede obtener tomando la raíz cuadrada de 150000

Cuadrado (150.000)

= 387,29833

El cuadrado del número entero da el valor cuadrado perfecto más alto antes de 150 000

Por lo tanto,

s = 387 =; 387

Cantidad total de árboles; s² = 387² = 149769

Answers

Answer:

60 students 140 adults

Step-by-step explanation:

so 200 into 3 : 7

first we just do this: 200 ÷ (3+7) = 200 ÷ 10 = 20

so a 1 in the ratio is 20 people

and theres 3 : 7

so 3 * 20 = 60

7 * 20 = 140

60 kids to 140 adults

Answer:

140 are students

Step-by-step explanation:

let k = number of kids

set up proportion based on 7 out of 10 are kids

Solve the following for the variable x.
3x - 16 = 38

Answers

Answer: x= 18

Step-by-step explanation:

3x - 16 = 38

38 + 16 = 54

3x/3 = 54/3

X= 18

Step-by-step explanation:

[tex] \tt{3x - 16 = 38}[/tex]

We want to remove the 16 first. So , Since the original equation is - 16 , we are going to use the oppsite operation and add 16 to both sides.

⟶ [tex] \tt{3x - 16 + 16 = 38 + 16}[/tex]

Simplify ! - 16 + 16 = 0 on the left. 38 + 16 = 54 on the right.

⟶ [tex] \tt{3x = 54}[/tex]

Now , we need to think how to remove the coefficient 3. Since the opposite of multiplication is division , we are going to divide both sides by 3.

⟶ [tex] \tt{ \frac{3x}{3} = \frac{54}{3}} [/tex]

Simplify ! 3 / 3 = 1 on the left and 54/3 = 18 on the right . So, our answer is 18.

[tex] \pink{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{x = 18}}}}}}}[/tex]

Answers

I got this right, look....

Evidence:

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

The ratios that have a unit rate greater than 1 are:

9/8 miles : 5/6 hours

4 miles : 3(1/3) hours

7 miles : 3/4 hours

What is a unit rate?

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

9/8 miles : 5/6 hours

4 miles : 3(1/3) hours

7 miles : 3/4 hours

The unit rate of each given ratio.

9/8 miles = 5/6 hours

Multiply 6/5 on both sides.

6/5 x 9/8 miles = 1 hour

54/40 miles = 1 hour

27/20 miles = 1 hour

1.35 miles = 1 hour

4 miles = 3(1/3) hours

4 miles = 10/3 hours

Multiply 3/10 on both sides.

3/10 x 4 miles = 1 hour

6/5 miles = 1 hour

1.2 miles - 1 hour

7 miles = 3/4 hours

Multiply 4/3 on both sides.

4/3 x 7 miles = 1 hour

28/3 miles = 1 hour

9.33 miles = 1 hour

We see that,

All of them have unit rates greater than 1.

Thus,

The ratios that have a unit rate greater than 1 are:

9/8 miles : 5/6 hours

4 miles : 3(1/3) hours

7 miles : 3/4 hours
