The ratio of boys to girls in the cafeteria is 2:3. If there are 135 kids in the cafeteria, how many are boys?

Answers

Answer 1

Answer:

54

Step-by-step explanation:

Let,

No. of boys = 2x

No. of girls = 3x

2x + 3x = 135

5x = 135

x = 135/5

x = 27

No. of boys = 2x = 2(27) = 54

What is the range of possible sizes for side x? _ < x < _

Answers

Answer:

  0.5 < x < 16.5

Step-by-step explanation:

The third side of the triangle must be longer than the difference of the other two sides:

  x > (8.5 -8.0)

  x > 0.5

And it must be shorter than their sum:

  x < (8.5 +8.0)

  x < 16.5

The third side must be in the range ...

  0.5 < x < 16.5

_____

These limits are a direct consequence of the triangle inequality, which requires the sum of the two shortest sides exceed the length of the longest side.

141x + 50 + 4x = 340
What is x?

Answers

Answer:

x = 2

Step-by-step explanation:

141x + 50 + 4x = 340

=> 145x + 50 = 340

=> 145x = 290

=> x = 2

Hoped this helped.

Simplify both sides of the equation

141x+50+4x=340(141x+4x)+(50)=340(Combine Like Terms)145x+50=340145x+50=340

Subtract 50 from both sides

145x+50−50=340−50145x=290

Divide both sides by 145

[tex] = > \frac{145x}{145} = \frac{290}{145} [/tex]

Sarah wanted to buy a TV. She had $390 in her pocket. The TV she wanted was $415; however she had a 10% off coupon. The sales tax is 6%. Does she have enough money to purchase the TV?

Answers

Answer: Sarah does not have enough money to purchase the TV.

Explanation: The total price is $395.91.

Answer:

No

Step-by-step explanation:

10% of 415

= 1/10 of 415

= 1/10 * 415

= $41.5

415 - 41.5 = $ 373.5

6% of 415

= 6% * 415

= $24.9

∴ $373.5 + $24.9 = $398.4

∴ Sarah cannot buy the TV as she is $ 8.4 short.

Answer:

C

Step-by-step explanation:

step 1

Address input values.

Input values:

The fraction number = 3/12

step 2

Write it as a decimal

3/12 = 0.25

0.25 is the decimal representation for 3/12

For Percentage Conversion :

step 1

To represent 0.25 in percentage, write 0.25 as a fraction

Fraction = 0.25/1

step 2

multiply 100 to both numerator and denominator

(0.25 x 100)/(1 x 100) = 25/100

25% is the percentage representation for 3/12

Answer:

-32

Step-by-step explanation:

first you need to find the unknown #(.666) and multiple it by 6 then add 4 then times 8 by for to get - 32.

Answer:

24x - 16

Step-by-step explanation

What we're doing here is factorisation

To factorise a number, you need to multiply the number outside of the bracket (in this case -4) by both of the inside numbers (-6x and 4).

First,

-4 x -6x

-4 x -6x = 24 ,   The x also needs to be kept- coming from the -6x, so the          answer would be 24x.

You may think that because there are minuses involved, the answer would be -24x but you need to remember the rule that 2 negatives make a positive!

Next,

Multipying the outside number by the second inside again:

-4 x 4 = -16

Alongside the rule that two negatives make a postive, another rule is that one negative and one positive always result in a negative.

Finally,

Connect both of these answers

24x - 16 is the answer!

(The minus/negative symbol in the final answer is because the second multipication turned out negative, if the second number was positive, the answer would be 24x + 16.)

Step-by-step explanation:

General arithmetic sequence formula: [tex]a_n=a_1+(n-1)d[/tex]

where [tex]a_1[/tex] = first term, and d = common difference.

The first term is -8

And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.

To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula

General formula: [tex]a_n=a_1+(n-1)d[/tex]

We have [tex]a_1=-8[/tex] and d = -7

So the formula to find the nth term would be
