Answer:

  (c)  3√3

Step-by-step explanation:

The altitude forms the long side of a 30°-60°-90° right triangle whose short side is 6/2 = 3 cm.

The ratios of side lengths in a 30°-60°-90° triangle are ...

  1 : √3 : 2

Multiplying these ratio values by 3 gives the right triangle side lengths of ...

  3 : 3√3 : 6

where 6 is the side length of the equilateral triangle. The length 3√3 is the altitude of that equilateral triangle.

The height of the triangle is 3√3 cm.

Answer: do you still need help?

Step-by-step explanation:

Answer:

Yes it is

Step-by-step explanation:

When we simplify 15:12, we receive 5:3

Therefore, 5:3 is equvilaent to 15:12

Using this unit ratio, we can solve for other rations

For example, 5:3, the unit ratio, times 2 is 10:6

5 * 2 = 10

3*2 = 6

10, 6 = 10:6

Answer:

$222

Step-by-step explanation:

6(32) + 30

192 + 30 = 222

Hence option B ,$222 is correct .

What is a function?

When we arrange numbers given to us in the pattern they follow and provide them with variables are called function.

How to solve?

zaria works $6 pr hour hence function becomes 6h she also receives $30 additional as bonus.

hence the function 6h+30

where h=32

hence 6*32+30=$222

Answer:

[tex]\boxed{\textsf{ The first negative term of the sequence is \textbf{-4} .}}[/tex]

Step-by-step explanation:

A sequence is given to us . And we need to find the first negative term of the sequence. So the given sequence to us is :-

[tex]\sf\implies Sequence = 31 , 26 , 21 , 16 ..... [/tex]

Here first term of the sequence is 31. And the common difference is 26 - 31 = -5 . Hence here (-5) is added to each number to obtain the second number of the sequence .

Here the last term mentioned is 16. And we are subsequently adding (-5) to each term to obtain the next term . Next third term will be obtained after adding 5×(-3) = -15 .

And that term will be , 16 - 15 = 1 .

Hence the last positive term is 1 . The next term term after adding (-5) will be the first negative term.

[tex]\sf \implies 1st \ negative \ term = 1 -5 =\pink{-4} . [/tex]

$20>$75>$60

Step-by-step explanation:

hope it helps

The system of inequalities that represent the situation are -

x < 20

y ≤ 60

x + y ≤ 75

We have $75 to spend on books and music and we want to spend less than $20 on music and no more than $60 on books.

We have to determine which system represents the situation.

Assume the cost spend on toffees is $x and that on chocolates is $y. Then-

x > 20

y < 15

x + y ≤ 50

Solve them graphically and you will find the possible solution set.

According to the question, we have -

Amount available to spend = $75

For music → amount < $20

For books → amount ≤ 60

Assume the cost spend on music is $x and that on books is $y.

Then -

x < 20

y ≤ 60

x + y ≤ 75

Check the graph attached for solution region. The points inside the  triangle formed (marked by red thick boundary) represents the points which satisfy the above conditions.

Answer:

There are 6 strawberry candies in the bag

Step-by-step explanation:

The probability of an event occurring = (The number of required outcome) ÷ (The number of possible outcome)

The given parameters in the question are;

The number of different types of fruit in Marina's bag = 3

The type of fruits in the bag = Lemon, watermelon, strawberry

The probability of choosing strawberry, P = 1/5

The number of lemon candies in the bag = 16

The number of watermelon candies in the bag = 8

Let, 'x', represent the number of strawberry candies in the bag

Therefore, by the definition of probability, we have;

P = 1/5 = x/(x + 16 + 8)

x + 16 + 8 = 5·x

16 + 8 = 5·x - x = 4·x

24 = 4·x

∴ x = 24/4 = 6

The number of strawberry candies in the bag, x = 6 strawberry candies.

Step-by-step explanation:

Answer:

Step-by-step explanation:

These binomials make up the difference of squares.

3x * 3x = 9x^2

3x * 5 = 15x

-5 * 3x = - 15x

-5 * 5 = - 25

Notice the 2nd and 3rd terms. They are equal except that one is plus and the other minus. That means they cancel. You are left with

9x^2 - 25

Using Pythagoras Theorem,

(AB)^2+ (AC)^2= (BC)^2

(9)^2+ (12)^2 = (BC)^2

81+144= (BC)^2

225= (BC)^2

BC= √225

BC= 15

Length of the longer stick = 45 cm

Step-by-step explanation:

Let the length of shorter stick be x cm

Therefore, length of longer stick = (x + 9) cm

According to the given information:

[tex] \frac{2}{5} (x + 9) = \frac{1}{2} x \\ \\ 2 \times \frac{2}{5} (x + 9) = x \\ \\ 4(x + 9) = 5x \\ \\ 4x + 36 = 5x \\ \\ 36 = 5x - 4x \\ \\ 36 = x \\ \\ x + 9 = 36 + 9 = 45 \\ [/tex]

Length of the longer stick = 45 cm
