There are 324 students in Jefferson middle school. 5/12 of the students are 7th graders. 1/4 of the students are 9th graders. The rest are 8th graders. How many students are 8th graders?

Answer:

17 is C

18 is add

19 is C

Step-by-step explanation:

Question 18 is worded a little weird.

so. (x^2)(x^3) = x^5, so you should add the expotents when you are multiplying them.

Answer:

The total surface area of this object is 510 cm^2.

Step-by-step explanation:

Here L = 12 cm, W = 7 cm and H = 9 cm.  

There are 2 panels 12 by 9 cm, 2 panels 12 by 7 cm, and 2 panels 7 by 9 cm.  The combined areas are:  

2(108 cm^2) + 2(84 cm^2) + 2( 63 cm^2)  =  510 cm^2 total area

Answer:

C

Step-by-step explanation:

The secant- tangent angle MLK is half the difference of the intercepted arcs, that is

[tex]\frac{1}{2}[/tex] (KN - KM) = 70° ( multiply both sides by 2 to clear the fraction )

KN - KM = 140°

KN - 61° = 140° ( add 61° to both sides )

KN = 201° → C

1 Escritura unida

Según la NGLE se unen las palabras que se interpretan como una unidad y en las que, por tanto, la marca de plural solo afecta al último elemento:[1]

el bajorrelieve, los bajorrelieves

la mediapunta, las mediapuntas

En un buen número de casos, el primer elemento puede seguir teniendo individualidad para parte de los hablantes y admitir la marca del plural. La Gramática admite algunos de esos casos, de modo que las dos formas son posibles, que se escribirán unidas o separadas según se dé ese plural o no:

el puercoespín, los puercoespines; el puerco espín, los puercos espines

el arcoíris, los arcoíris; el arco iris, los arcos iris

el medioambiente, los medioambientes; el medio ambiente, los medios ambientes.

el pavorreal, los pavorreales; el pavo real, los pavos reales

La Gramática prefiere, como norma general, la forma en una palabra.

Answer:

x = 2

Step-by-step explanation:

First, add like terms:

2x + 8x - 11 = 9

10x - 11 = 9

Add 11 to both sides:

10x = 20

Divide each side by 10

x = 2

So, the answer is x = 2

Answer:

4 and 1/2 hours or 270 minutes

Step-by-step explanation:

Each student spend 30 minutes to set up the puppet show.

+30

They spent twice as long to put everything away.

+30 +30

Current total: 90 minutes

The show was open for three hours

+180 (60 minutes in an hour x 3 hours)

Current total: 270

Total: 270 minutes

OR

Divide 270 by 60 minutes in an hour, which would be 4.5 hours.

Answer: 1 hour and 30

Step-by-step explanation:

First, you multiply 30 minutes x2 and get 60. 60 minutes is an hour so now you have an hour. Then you add 30 minutes to that and get 1 hour and 30 minutes. Then, you subtract 3 hours minus 1 hour, and 30 minutes and get 1 hour and 30 minutes.

Answer:

x = 12

Step-by-step explanation:

81 + 57 + 2x + 18 = 180

156 + 2x = 180

2x = 24

x = 12

If the measures of triangle are  81⁰, 57⁰ and (2x+18)⁰then value of x is 12.

A triangle is a three-sided polygon that consists of three edges and three vertices.

The given triangle has three angles 81⁰, 57⁰ and (2x+18)⁰

According to the angle sum property.

The sum of three angles of triangle is 180⁰

81⁰+57⁰+(2x+18)⁰=180⁰

81+57+2x+18=180

We need to find the value of x of for eighty one plus fifty seven plus two times of x plus eighteen equal to one hundred eighty.

Add 81, 57 and 18

156+2x=180

Subtract 156 from both sides

2x=180-156

2x=24

Divide both sides by 2

x=12

Hence the value of x is 12.

Answer:

Krystal collected 315 pop-can tabs while Natasha collected 565 pop-can tabs.

Step-by-step explanation:

Let x be number of pop-can tabs Krystal collected

Krystal: x

Natasha: x + 250

x + x + 250 = 880

2x = 880 - 250

2x = 630

x = 315

Krystal: 315 pop-can tabs

Natasha: 315+250 = 565 pop-can tabs
