Answer:

So you can either buy all roses or all carnations, or spend $30 on each kind:

12 roses

10 carnations

6 roses & 5 carnations

Step-by-step explanation:

If you buy a combination of roses and carnations, the amount of money you spend on each has to be a multiple of both 5 and 6. Since these are relatively prime, their least common is 5(6) = 30.

note: the reason it has to be a common multiple of 5 and 6 is because the total amount - 60 - is a common multiple.

Answer:

volume of cuboid = 2h(l+b)

Step-by-step explanation:

since you are asking the method on how to do this I will just help you out with basic idea.

first,

convert mixed fractions into fractions before writing them in given.

eg:

GIiven,

width(b)= (7×2+1)/2 = 15/2= 7.5 in

then you can find out the length by doubling the width since the question has said the length is twice the width.

after that we can find out the height by subtracting (2×2+1)/2 = 5/2= 2.5 in from the length.

finally figure out the volume by using formula for volume of cuboid i.e 2h(l+b)

Points on the graph:

(-1.5, 4.5), (3.5, 3.5)

Graph of points (-1.5, 4.5) and (-3.5,3.5) is given in attachment.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The given points are minus one point five comma four point five and minus three point five comma three point five.

(-1.5, 4.5) and (-3.5,3.5)

A coordinate plane is a tool used for graphing points, lines, and other objects

To point these points first we have to consider two lines, horizontal line and vertical line.

The horizontal line is called as X axis and vertical line is called as Y axis.

Then we have to pair (-1.5, 4.5) and (-3.5,3.5) with (x, y) coordinates.

Hence the given graph is the required answer.

Answer:

m= 27

Step-by-step explanation:

m° +66° +m°= 120° (vert. opp. ∠s)

Simplify:

2m° +66°= 120°

2m°= 120° -66°

2m°= 54°

Divide both sides by 2:

m°= 54° ÷2

m°= 27°

m= 27

Step-by-step explanation:

The fraction of the shape that is circle is  9/32.

A circle is known to have a kind of round figure that does not have any  corners or edges. They are said to be closed and two-dimensional curved shape. e.g. wall clock, a lollipop. etc.

For better understanding, note that:

The Total Black Shapes  is = 5 : 11 and then you divide by 2 to give

 10 : 22

The ratio for the white shapes is  3 : 7

Then you Sum up the units = 3 + 7 = 10

To Find the equivalent ratio for the total shapes, one has to know:

Black squares = 3 : 8  and then Multiply by 2:

Black circles  is said to be Black squares and their ratio is = 6 : 16

The Sum of the units = 6 + 16 = 22

Then you have to combine the ratios all together:

Therefore White circles : white squares : black circles : black square = 3 : 7 : 6 : 16

The Circles = 3 + 6 = 9 units

Total = 3 + 7 + 6 + 16 =32 units

The fraction of all the shapes that are circles = 9/32

Therefore,  9/32 of the shapes found are circles.

Answer:

Step-by-step explanation:

It should be noted:

Area of square garden = L² = 256

Square root both sides of the equation to find the length of the square garden. Then, use the length of the square garden to calculate the length of fence required for 3 sides of the garden.

Square root both sides.

√L² = √256

=> L = 16

Multiply the length by 3.

3L = 16 x 3 = 48 feet

Thus, Mr. Campbell will need 48 feet of fencing.

Answer:

x = 1 and y = -8/3

step-by-step explanation:

solve for x

[tex]\sf 6x+3\left(\frac{4}{3}x-4\right)=-2[/tex]

[tex]\sf 6x+4x-12=-2[/tex]

[tex]\sf \rightarrow 10x = -2 +12[/tex]

[tex]\sf \rightarrow 10x = 10[/tex]

[tex]\sf \rightarrow x = 1[/tex]

solve for y

[tex]\hookrightarrow \sf y = \frac{4}{3} x-4[/tex]

[tex]\hookrightarrow \sf y = \frac{4}{3} (1)-4[/tex]

[tex]\hookrightarrow \sf y=-\frac{8}{3}[/tex]

Answer:

x=1 and y=-8/3

Step-by-step explanation:

The easiest way to solve this is by substitution because the first equation is already in slope-intercept form.

First, take y= 4/3x -4 and substitute it into the second equation as follows: 6x + 3(4/3x -4) = -2

Next, simplify that equation to get 6x + 12/3x -12 = -2.

After that, combine all like values: 10x - 12 = -2.

Finally, add 12 to each side and divide by 10 to get x=1.

To find the y-value, substitute x=1 into either equation and solve for x (I'm choosing the first equation). y= 4/3(1) -4

In order to make simplifying this easier, I find that -4 = -12/3.

Finally, simplify: y= 4/3 - 12/3 = -8/3.

The solution to the system of equations is (1, -8/3), or x=1 and y=-8/3.

Finally complement of the supplement of twice the angle 60°=90°-60°=30

60 degrees angle is an acute angle because it is less than 90 degrees. 60° in radians is π/3 and the measure of each angle of an equilateral triangle is 60°. Therefore, it is also called a 60-degree angle triangle.

No. You can see this because the length of the box is 21, whilst the length of the wand is 22.

Answer:

Yes, it can fit in.

Using Pythagoras theorem:

Find bottom side, hypotenuse

a² + b² = c²

6² + 21² = (bottom side)²

bottom side = √477

bottom side = 3√53 cm

Then find upper diagonal, hypotenuse

(3√53)² + 5² = diagonal²

diagonal = √502

diagonal = 22.4 cm

Thus the wand can fit in the box diagonally.
