Write an equation for the proportional relationship shown in the table.
x 0.5 1 1.5 2
y 27 54 81 108

Step-by-step explanation:

the total surface area is the sum of the individual areas.

we have the ground area : a 6×6 square. = 36 cm²

and we have 4 equal triangles.

the area of a triangle is baseline × height / 2.

which is for each of these triangles

6 × 12 / 2 = 3 × 12 = 36 cm²

so, the total surface area of the pyramid is

36 + 4×36 = 5×36 = 180 cm²

Solution:

We know that:

This means that:

First, let's find the area of the triangle and square. Then, substitute them in the surface area equation to find the surface area of the pyramid.

Hey there!

12 pieces make a dozen

12 pieces uses 2 cup of flour

That means per flour is 6

=> 6s = 36

Substitute 6s = 36

=> 6s = 36 { obtain a formula for s}

=> s = 36/6 { Divide}

=> s = 6

Therefore, they need 6 scoops of flour

Answer:

3x-3

expanding the brackets

3 times x and -1 times 3

Answer: x = 15

Step-by-step explanation:

The perimeter is the sum of the 2 lengths and 2 widths.

Step 1: 2 times the length is 4x + 10

Step 2: 2 times the width is 2x - 20

Step 3: Add the both results together.

6x - 10

Step 4: Create an algebraic equation.

6x - 10 = 80

Step 5: Solve for x.

6x = 90

6x/6 = 90/6

x = 15

y = -9.5 + x/4

Step-by-step explanation:

1. x-4y=38

-x -x

2. -4y= 38-x

/-4 /-4 /-4

3. y= -9.5 + x/4

The equation of a line x- 4y = 28 in slope intercept form is y = (1/4)x - 7.

Slope can be defined as the rate of change of the y-axis with respect to the x-axis. Slope can also be thought of as rise over run which is (y₂-y₁)/(x₂-x₁).

We know the equation of a line in slope intercept form is y  mx + b.

Where slope = m, y-intercept = b, and (x,y) are the points that lie on the line.

Given x - 4y = 28.

-4y = - x + 28.

4y = x - 28.

y = (1/4)x - 7.

Answer:

  c.  Upward facing parabola-shaped; y-intercept (0, -5); symmetrical with respect to the y-axis

Step-by-step explanation:

The positive leading coefficient tells you the graph opens upward. (Eliminates B and D)

The constant -5 tells you the y-intercept is -5. (Eliminates A, which shows an x-intercept, not a y-intercept.)

The function is a vertical translation and scaling of the parent function y=x². There is no translation left or right, so the axis of symmetry remains the y-axis.

Question :-

Answer :-

Explanation :-

As per the provided information in the given question, we have been given that Lenght of the Rectangle is 12 cm and Breadth of the Rectangle is given 10 cm . And, we have been asked to calculate the Area of Rectangle .

For calculating the Area of Rectangle , we will use the Formula :-

[tex] \bigstar \: \: \boxed{ \sf{ \: Area \: of \: Rectangle \: = \: Length \: \times \: Breadth \: }} [/tex]

Therefore , by Substituting the given values in the above Formula :-

[tex] \dag \: \: \: \sf {Area \: of \: Rectangle \: = \: Length \: \times \: Breadth} [/tex]

[tex] \longmapsto \: \: \sf {Area \: of \: Rectangle \: = \: 12 \: \times \: 10} [/tex]

[tex] \longmapsto \: \: \textbf {\textsf {Area \: of \: Rectangle \: = \: 120 \: cm² }} [/tex]

[tex] \underline {\rule {190pt} {4pt}} [/tex]

The area of the given rectangle.

[tex]area = length \times width[/tex]

[tex]a = 12 \times 10[/tex]

[tex]a = 120 \: {cm}^{2} [/tex]

Therefore, the area of the given rectangle is 120 square centimeters.

The angles FGH and FJH are corresponding angles

The measure of angle mFJH is 46,2 degrees

The given parameters are:

mFGH = (6x + 21) and mFJH = (17x - 28),

To calculate the angle FJH, we make use of the following equation

mFGH = mFJH

So, we have:

6x + 21 = 17x - 28

Collect like terms

17x - 6x = 21 + 28

Evaluate

11x = 48

Divide both sides by 11

x = 48/11

Recall that:

mFJH = (17x - 28),

So, we have:

mFJH = 17 * 48/11 - 28

mFJH = 46,2

Hence, the measure of angle mFJH is 46,2 degrees

Step-by-step explanation:

1) 2:5 ratio

This is a fairly simple process, you count how many of each and then put them in order the way the question asks.

So there are 5 cans and 2 bottles. The question asks "bottles to cans" so the correct answer HAS to be 2:5, NOT 5:2.

2) 3:1

There is 1 spoon and 3 forks. The question asks "forks to spoons" so the correct answer HAS to be 3:1, NOT 1:3

There is $2.4 less is the sale price of the black coat than the sale price of the blue coat.

Discount is a kind of reduction or deduction in the cost price of a product.

Given

Maria is trying to decide which one of two winter coats she should buy.

The blue coat usually costs $48 but is on sale for 25% off.

The black coat usually costs $56 but is on sale for 40% off.

The cost of the blue coat after 25% discount;

[tex]= 48\times \dfrac{25}{100}\\\\= 48 \times \dfrac{1}{4}\\\\= 12[/tex]

The cost of the blue coat after discount = $48 - $12 = $36

The cost of the black coat after 40% discount;

[tex]= 56 \times \dfrac{40}{100}\\\\= 56 \times 0.40\\\\=22.4[/tex]

The cost of the black coat after discount = $56 - $22.4 = $33.6

The price of the coat less is the sale price of the black coat than the sale price of the blue coat is;

= $36 - $33.6

= $2.4

Hence, there is $2.4 less is the sale price of the black coat than the sale price of the blue coat.
