Step-by-step explanation:
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.
What is Graph?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:
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.
A driver can deliver his newspapers in 80 minutes. His friend can take care of the same route in 2 hours. How long would it take them to do the job together?
Using the together rate, it is found that it would take them 48 minutes to do the job together.
What is the together rate?The together rate is the sum of each separate rate.
In this problem, consdering the measures in minutes:
The driver's ratio is of [tex]\frac{1}{80}[/tex].His friend's ratio is of [tex]\frac{1}{120}[/tex].The together ratio is of [tex]\frac{1}{x}[/tex].Hence:
[tex]\frac{1}{x} = \frac{1}{80} + \frac{1}{120}[/tex]
[tex]\frac{1}{x} = \frac{3 + 2}{240}[/tex]
[tex]x = \frac{240}{5}[/tex]
[tex]x = 48[/tex]
It would take them 48 minutes to do the job together.

A wizard walks into a wand shop to
purchase a magic wand. He chooses
a wand that is 22 cm long. Will the
wand fit into the box shown? Explain.
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.

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)

Answer:
x = 1 and y = -8/3
step-by-step explanation:
In order to solve this, insert equation 1 into 2solve 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.

Mr. Campbell has a square garden with an area of 256 square feet. He wants to put a fence along 3 sides of the garden. How many feet of fencing will he need?
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.

White shapes and black shapes are used in a game.
Some of the shapes are circles.
All the other shapes are squares.
О
The ratio of the number of white shapes to the number of black shapes is 5:11
The ratio of the number of white circles to the number of white squares is 3:7
The ratio of the number of black circles to the number of black squares is 3:8
Work out what fraction of all the shapes are circles.
The fraction of the shape that is circle is 9/32.
What is a Circle's Shape?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.

An angle measureless 60 degrees the measure of it complementary angle. What is the measure of each angle
Step-by-step explanation:
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.
please mark me as brainlist pleaseGiven :
An angle which measures less 60° the measure of its complementary angle.⠀
To Find :
The measure of its complementary angle.⠀
Solution :
Let's assume the one of the complementary angle as "x" and the other angle as (x - 60)° .
Now,
According to the Question :
[tex]\: \qquad \dashrightarrow \sf{{x {}^{ \circ} + (x - 60) {}^{ \circ} = {90}^{ \circ} }}
[/tex]
[tex]\: \qquad \dashrightarrow \sf{{x {}^{ \circ} + (x - 60) {}^{ \circ} = {90}^{ \circ} }}
[/tex]
[tex]\: \qquad \dashrightarrow \sf{{x {}^{ \circ} + x {}^{ \circ} - 60 {}^{ \circ} = {90}^{ \circ} }}
[/tex]
[tex]\: \qquad \dashrightarrow \sf{{{2x}^{ \circ} = {90}^{ \circ} + 60 {}^{ \circ} }}
[/tex]
[tex]\: \qquad \dashrightarrow \sf{{{2x}^{ \circ} = 150 {}^{ \circ} }}
[/tex]
[tex]\: \qquad \dashrightarrow \sf{{x = \dfrac{150 {}^{ \circ}}{2 {}^{ \circ}} }}
[/tex]
[tex]\: \qquad \dashrightarrow \bf{{{x}^{ \circ} = 75 {}^{ \circ} }}
[/tex]
Therefore,
One angle = 75°Other angle = 75° – 60° = 15°⠀
Henceforth ,
The measure of the two angles are 75° and 15° .
