Chill dude.                          

Stop with the all caps.    

25 is the answer.

G = green sweets

Ratio of blue to green = 3:5

Ratios are essentially fractions, and can be converted into fraction form

Therefore, number of blue sweets is 3/5 of green sweets, which can also be represented as 3/5g

Number of green sweets to red sweets is 6:1

We can also flip this ratio around and the ratio would still have the same value.

Number of red sweets to green sweets = 1:6

In fraction form, the number of red sweets is 1/6 of green sweets, which is also 1/6g.

Since there are less than 270 sweets in the box, we can use this expression to represent the sweets in the box:

G + 3/5g + 1/6g < 270

Find a common denominator for the fractions.

5 * 6 = 30, thus a common denominator would be 30.

Since G is a variable with no coefficient, 1 would be implied because no coefficient is present.

So when multiplying G to get a common denominator, the numerator would be 30. 30/30 = 1

G * 30 = 1 * 30

G = 30/30g

Multiply the rest of the numerators and you’ll get:

30/30g + 18/30g + 5/30g < 270

Add.

1 + 18/30g + 5/30g = 1 23/30g

Convert this into an improper fraction.

53/30g < 270

Now divide both sides by 53/30.

(53/30g) ÷ (53/30) < 270 ÷ (53/30)

= g < 270 ÷ (53/30)

Dividing fractions is complex, so you can simply switch the numerator and denominator and multiply:

G < 270 x (30/53)

= g < 8,100/53

Since the number of red sweets to green sweets is 1/6g the number of green sweets, the number of red sweets is 1/6 of 8,100/53.

R = red sweets

R < 8,100/53 x 1/6

8,100 x 1 = 8,100

53 x 6 = 318

R < 8,100/318

318 goes into 8,100 25 times, regardless of any remainder.

Therefore, the greatest possible number of red sweets in the box is 25 red sweets.

A 30 foot ladder is set against the side of a house so that it reaches up 24 feet. If Alexander grabs the ladder at its base and pulls it 10 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 14 ft.) Round to the nearest tenth of a foot.

Answers

Answer:

The answer would be 10.8

Step-by-step explanation:

By finding the missing base side on the original triangle (which is 18), we add 10 to that number to find the base side on the second triangle. We can then use the equation "sin(21.04) = x/30" to find the missing length side (21.04 is the degree measurement).

Hope this helps :)

The height of the wall till the ladder reaches in when it grabs 10 feet farther will be 10.77 feet.

What is a triangle?

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

The ladder is making a right-angle triangle with a wall as shown below.

By Pythagoras's theorem,

x² = 30² - 24²

x = 18

By Pythagoras's theorem,

y² = 30² - (18 + 10)²

y = 10.77 feet

Hence "The height of the wall till the ladder reaches in when it grabs 10 feet farther will be 10.77 feet".

At a game booth, a student gets a box of candy as the prize for winning a game. The boxes come in four colors: white, red, green, and blue. There are 10 boxes of each color. All the boxes are equally likely to be given away as prizes. Which expression shows the probability of the first winner receiving a white box and the second winner also receiving a box of the same color? (1 point)

Select one:
a. (10/40) * (9/39)
b. (10/40) * (10/39)
c. (10/40) + (9/39)
d. (10/40) + (10/39)

Answers

Answer:

a. (10/40) * (9/39)

Step-by-step explanation:

Since, the total number of white box = 10,

Red box = 10,

Green box = 10,

And, Blue box = 10,

Thus, the total number of boxes = 10 + 10 + 10 + 10 = 40

The probability of receiving white box by first winner =  White box / Total box = 10/40

Since, the replacing is not allowed ( Because, here boxes are allotted )

Thus, the remaining white box = 10 - 1 = 9,

And, the remaining total boxes = 40 - 1 = 39,

Thus, the probability of receiving white box by second winner = Remaining white box / Remaining total box = 9/39

Hence, the probability of the first winner receiving a white box and the second winner also receiving a box of the same color = 10/40 * 9/39

Which is required expression.

Answers

Answer:

Hello! answer: x = 11

Step-by-step explanation:

These are vertical angles in simple terms meaning they are across from each other and if you folded them over each other they would match up and they will equal the same measure so 13 × 11 = 143 143 - 10 = 133 therefore x = 11 Hope that helps!

X = 11
Both of those angles are equal to each other, so 133= 13x-10, add 10 from both sides to cancel out the “-10”. You get 143=13x and then divide both sides by 13 and you get x= 11
