The proportion is solved and the number of roses is R = 21

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

If the ratio of daisies to roses is 2:7, this means that for every 2 daisies, there are 7 roses.

If there are 6 daisies, we can use this ratio to find out how many roses there are.

2 daisies = 7 roses

On simplifying the proportion , we get

1 daisy = 7/2 roses (dividing both sides by 2)

So, if there are 6 daisies:

6 daisies = (7/2) x 6 = 21 roses

Hence , there are 21 roses

Answer:

the area of a triangle is 9 because 4.24 times 4.24 equals 17.9776 estimated is 18 divided by 2 is 9 times 4 is 36. Now we divide 36 by 2 so we know what the area of the two trapezoids so we know the top and the bottom which is 18. The area of the square in between the triangles is 4.24 times 6 which is 25.22 estimated is 26. Now we add 26 with 18 which is 34. Now we have to find the area of the rectangle to do this we need to multiply 7.24 and 2 we need to do this so we know the length of the rectangle which is 14.48 estimated is 14. Now that we know the length we multiply it with the height which is 6, 14 times 6 equals  84.

84 is the rectangles area and the area for the trapezoids is 36.

84 plus 18 plus 18 equals 120 squared

Answer:

.2 degrees

Step-by-step explanation:

180-170 is 10

10/50 is .2

The size of the other angle will be 0.2 degrees.

A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

It is given that a polygon has 50 sides but one of its angles is 170 degrees.

The remaining angle will be calculated as:-

180-170 = 10

The size of the other angle is calculated below:-

Angle = 10/50

Divide the value 10 by 50 to get the angle.

Angle = 0.2

Therefore, the size of the other angle will be 0.2 degrees.

Answer:-5+x<-1

Step-by-step explanation:

Answer:

H. -5 + x < -1

Step-by-step explanation:

Okay so let's first look at our little graph thing. What is it saying? It's telling us that what ever x is, it is NOT 4 (because the circle is not filled in) and it is less than 4 (because it's all shaded in before 4). Now that we know this, lets look at our possible answers.

F. x - 3 < 7

Now, for all of these possible answers, we can solve them exactly like normal equations (like x - 3 = 7).

x - 3 < 7

[add 3 to both sides to leave the x by itself]

x < 10

Whoa, that's not right! We don't even have 10 on our graph, so F is out of the running.

G. x + 6 [tex]\leq[/tex] 10

Okay, let's work smarter, not harder here. So we can see that there is a greater than or equal to sign there. So even if we solve it and we get 4 as the answer, our graph doesn't include 4. So we can throw this answer out right away.

H. -5 + x < -1

Solve like a normal equation in the first one.

-5 + x < -1

[add 5 to both sides to leave the x by itself]

x < 4

Hey! We got something! So let's read this with words. So whatever x is, it does not include 4, and is less than 4. So now looking back on our first brainstorm of the graph, this is in line with what we want.

So this is the answer! Yay!

Just for fun let's look at the last possible answer.

I. x - 8 > -4

Again, solve like a normal equation.

x - 8 > -4

[add 8 to both sides to leave x by itself]

x > 4

Oh! Another 4! But this time the sign is different. Let's read it again with words. So whatever x is, it does not include 4 (ok, good), and is greater than 4 (oh, not good). Our graph showed us that x is less than 4. So this answer is not the answer.

So again, we keep H. as our correct answer.

Answer: 8 girls

Step-by-step explanation:

The team is split into groups that have the same ratio as the whole team.

This means that every group must obey this ratio:

12 girls  :   18 boys

At the lowest form (dividing both sides by 6), the ratio is:

2    :    3

Every group must therefore be in a ratio of; 2 : 3.

In a team group that has 12 boys, the number of girls is:

2    :    3

x    :    12

3x = 24

x = 24 / 3

x = 8 girls

Step-by-step explanation:

16cos(30)-20sin(60) -8sin(90)

look at the pattern of the numerators Millie, you can remember all of the sin and cos  functions at the special angles now. :)

sin(0) = 0 / 2

sin(30) = 1 / 2

sin(45) = [tex]\sqrt{2}[/tex] / 2

sin(60) = [tex]\sqrt{3}[/tex] / 2

sin(90) = [tex]\sqrt{4}[/tex] / 2   aka  1

now the numerators just count up from 90°

cos(90) = 0 / 2

cos(60) = 1 / 2

cos(45) = [tex]\sqrt{2}[/tex] / 2

cos(30) = [tex]\sqrt{3}[/tex] / 2

cos(0) =  [tex]\sqrt{4}[/tex] / 2   aka  1

see the pattern.. it's pretty easy to memorize, knowing that :)

now let's use the above to plug into the given equation

16* [tex]\sqrt{3}[/tex] / 2 - 20* [tex]\sqrt{3}[/tex] / 2- 8*[tex]\sqrt{4}[/tex] / 2

8* [tex]\sqrt{3}[/tex] - 10 [tex]\sqrt{3}[/tex]  -8

-2*[tex]\sqrt{3}[/tex]  - 8

this isn't quite the same answer as you got before.. I feel like it's right

Step-by-step explanation:

Given that:

Greatest whole number that round to 400,000 when rounding to the nearest hundred thousand :

To obtain the greatest whole number which rounds to 400,000, the whole number is greater Tha 400,000 and its 10 thousand digit in the number or value to be rounded must be lesser than 5.

The value would be 449,999 ; here z the 10 thousand value which is 4 is rounded to zero since it is not up to 5 and the subsequent digits also rounded to 0 to give ;

400,000 (nearest hundred thousand).

Length of the rectangle = [tex]x+4[/tex]

Width of the rectangle = [tex]x[/tex]

The perimeter of the rectangle is less than 140.

To find:

The inequality for the given situation and solve it.

Solution:

We have,

[tex]l=x+4[/tex]

[tex]w=x[/tex]

We know that, the perimeter of a rectangle is

[tex]P=2(l+w)[/tex]

[tex]P=2(x+4+x)[/tex]

[tex]P=2(2x+4)[/tex]

[tex]P=4x+8[/tex]

It is given that the perimeter of the rectangle is less than 140.

[tex]P<140[/tex]

[tex]4x+8<140[/tex]

[tex]4x<140-8[/tex]

[tex]4x<132[/tex]

Divide both sides by 4.

[tex]x<\dfrac{132}{4}[/tex]

[tex]x<33[/tex]

Therefore, the correct option is A because the sign of inequality is < and the solution of inequality is [tex]x<33[/tex].
