The equation that represents the number of T-shirt , number of colours of shirt and total order is 3x + 50xy.

The number of colours and T- shirts are the variable quantity while the cost of order is the fixed quantity.

The number of members in the school choir = 75

The charge for one shirt = $3

Let the number of T-shirts ordered be x

Cost of ordering x shirts = 3x

Therefore,

Charge for each colour to be printed = $50

Let the number of colours to be printed on each T- shirt be represented by y

Therefore,

Cost of printing y colours on each T- shirt = 50y

Cost of printing y colours on x number of T-shirts = x(50y) = 50xy

Hence, the equation that represents the number of T-shirt , number of colours of shirt and total order is as follows:

Total cost  = 3x + 50xy

Hence, the fixed quantity and variable quantity are as follows:

The number of colours on the shirts is a variable quantity

The number of shirts ordered is a variable quantity

The cost of order is fixed quantity

Answer:

The number inside radical is 29

Step-by-step explanation:

Given:

To find:

Distance Formula:

[tex]\displaystyle \large{\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}[/tex]

Determine (x2,y2) = (1,1) and (x1,y1) = (3,-4). Therefore:

[tex]\displaystyle \large{\sqrt{(1-3)^2+(1-(-4))^2}}\\\displaystyle \large{\sqrt{(-2)^2+(1+4)^2}}\\\displaystyle \large{\sqrt{4+5^2}}\\\displaystyle \large{\sqrt{4+25}}\\\displaystyle \large{\therefore \sqrt{29}}[/tex]

Therefore, the number inside the radical is 29

Answer:

[tex]\sqrt{29}[/tex]

Step-by-step explanation:

Hi there!

We are given the points (1, 1) and (3, -4)

We want to find the distance between the points

Distance can be found using the formula [tex]\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We can label the values of the points first, before calculating to help avoid confusion and mistakes.

[tex]x_1 = 1\\y_1 = 1\\x_2 = 3 \\y_2 = -4[/tex]

Now substitute these values into the formula

d = [tex]\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]

d = [tex]\sqrt{(3-1)^2 + (-4-1)^2}[/tex]

Now, using order of operations, first simplify what is in the parentheses:

d = [tex]\sqrt{(2)^2 + (-5)^2}[/tex]

Now raise 2 and -5 to the second power.

d = [tex]\sqrt{4 + 25}[/tex]

Add the numbers together under the radical

d = [tex]\sqrt{29}[/tex]

The distance is [tex]\sqrt{29}[/tex]

Hope this helps!

Answer:

see explanation

Step-by-step explanation:

you are looking for perfect square factors of the numbers under the radical sign. both numbers and the sum are irrational because they contain √5

125 = 5×25

80 = 5×16

3√125 = 3√(25×5) = 3×5√5 = 15√5

√80 = √(16×5) = 4√5

1)  15√5 + 4√5 = 19√5      the √5 is the same square root so you add the coefficients

perfect square factors are bold

4×√(25×2)×√(9×2) =

4×5×3×√(2×2) =

60×√4 =

2)  60 × 2 = 120

the numbers are both irrational but the answer is rational because √2 ×√2 = √4 = 2

Answer:

x = 150

y = 30

Step-by-step explanation:

x° = 5y° (corresponding angles) (1)

x° + y° = 180° (Linear pair angles) (2)

From equations (1) and (2), we find:

5y° + y° = 180°

-> 6y° = 180°

-> y° = 180°/6

-> y° = 30°

-> y= 30

-> x° = 5(30°) = 150° (From equation 1)

-> x = 150

Using a system of equations, it is found that:

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

The theater was full, hence:

x + y + z = 277.

There are half as many adults as there are children, hence:

x = 2z.

The theater charges $5.00 for children, $7.00 for students, and $12.00 for adults. The total ticket sales were of $2002, hence:

5x + 7y + 12z = 2002.

Replacing the second equation into the other two:

y + 3z = 277 -> y = 277 - 3z

7y + 22z = 2002.

Then:

7(277 - 3z) + 22z = 2002

z = 63

y = 277 - 3z = 277 - 3 x 63 = 88

x = 2z = 2 x 63 = 126.

Answer:

  104 feet

Step-by-step explanation:

The Pythagorean theorem can be used to find the hypotenuse of a right triangle with legs 40 feet and 96 feet. It tells you ...

  h² = 40² +96²

  h² = 1600 +9216 = 10816

  h = √10816 = 104

The distance from one corner to the opposite corner is 104 feet.

______

Additional comment

You may recognize that the ratios of the given lengths are 40:96 = 5:12. These match the legs in the Pythagorean triple (5, 12, 13). This tells you the third side (diagonal) of the triangle is 13 ratio units, or 13×(8 ft) = 104 ft.

Answer:

x = 0.71; y = 2.43

Step-by-step explanation:

y = 2x + 1

y = 9x - 4

9x - 4 = 2x + 1

7x = 5

x = 5/7

y = 2x + 1

y = 2(5/7) + 7/7

y = 10/7 + 7/7

y = 17/7

x = 0.71; y = 2.43

Answer:

517

Step-by-step explanation:

We can draw a Venn diagram to represent the data.

First, identify the groups.

Then draw the Venn diagram to represent the groups.

Given 73 students study all subjects:

E ∩ M ∩ S = 73   (add this to the middle section)

Next, add the numbers for the sections where the students study 2 topics.

E ∩ M but not S:  152 - 73 = 79

M ∩ S but not E:  79 - 73 = 6

S ∩ E but not M:  139 - 73 = 66

Now complete each circle by making sure that the values add up to the total value given.

Only E = 254 - S ∩ E - E ∩ M - E ∩ M ∩ S = 254 - 66 - 79 - 73 = 36

Only M = 280 - E ∩ M - M ∩ S - E ∩ M ∩ S = 280 - 79 - 6 - 73 = 122

Only S = 280 - M ∩ S - S ∩ E - E ∩ M ∩ S = 280 - 6 - 66 - 73 = 135

To find the total number of students in the school, add the numbers in each section of the Venn diagram:

73 + 79 + 6 + 66 + 36 + 122 + 135 = 517
