From the first diagram shown, we can see that 1 cupcake costs $1.5

To get the price of 5 cupcakes

Since 1cupcake = $1.5

5 cupcakes = $x

cross multiply

1 * x = 5 * 1.5

x = $7.5

Hence 5 cupcakes will cost $7.5

Since 1cupcake = $1.5

18 cupcakes = $x

cross multiply

1 * x = 18 * 1.5

x = $27

Hence 5 cupcakes will cost $27

To get the number of cupcakes priced $18

Since 1cupcake = $1.5

x cupcake = $18

1.5x = 18

divide both sides by 1.5

1.5x/1.5 = 18/1.5

The converted money in Canadian dollars is $111.6.

Given that, Irlene has just returned from a business trip in Britain with £200 of uncashed traveler's cheques.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the converted Canadian dollars be x.

x = 200 × 0.5544 + 0.65% of 200 × 0.5544

= 110.88 + 0.0065 × 110.88

= 111.60072

≈ 111.6

Therefore, the converted money in Canadian dollars is $111.6.

To get the fraction of the square shaded we would use the rows and columns

For the row:

The total on the 1st row = 1

The first row is divided into 10. This means each box in the first row: 1/10

One of the box is shaded. This implies the fraction shaded in the first row is 1/10

For the column:

The total on the 1st column = 1

The column is also divided into 10 box which means each box represent 1/10

Since one of the box in the column is shaded, it represent 1/10

Fraction of the whole square shaded = fraction shaded in the row × fraction shaded in the column

Fraction of the whole square shaded = 1/10 × 1/10

Fraction of the whole square shaded = 1/100

So answer is,

We are given the equality

and told to solve for a. That is, we should apply mathematical operations on both sides of the equality so we "isolate" variable a on one side of the equality. We start by multiplying both sides by a, so we get

Now, we subtract 2a from both sides. We get

We can factor on the left side a as a common factor, so we get

Finally, we divide by (g-2) on both sides, so we get

The decibel value for this cats purr round to the nearest decibel is; 25

Decibel (dB) is a unit for expressing the ratio between two physical quantities, such as measuring the relative loudness of sounds. One decibel (0.1 bel) is equal to 10 times the common logarithm of the power ratio.

Decibels are a unit of measure used to describe how loud a sound is. Now, I₀ is the intensity of threshold sound, which is sound that can barely be perceived by the human ear.

The loudness of a sound, in decibels, with intensity I is given by;

dB = 10 log₁₀(I/I₀)

We are given the intensity of a cat’s purr as I = 320I₀

Thus;

dB = 10 log₁₀(320I₀/I₀)

dB = 10 log₁₀(320)

dB = 25.05 ≈ 25

In order to determine the ratio of the perimeters for the given rectangles, first calcualte their perimeters. Use the following formula:

P = 2w + 2l

w: width

l: length

For the smaller rectangle you have:

w = 2cm

l = 4 cm

P = 2(2cm) + 2(4cm) = 4cm + 8cm = 12cm

For the bigger triangle you have:

w' = 4cm

l' = 8cm

P' = 2(4cm) + 2(8cm) = 8cm + 16cm = 24cm

Then, you have:

P/P' = 12cm/24cm = 1/2

Hence, the ratio is 1:2

Answer:

1728 cm ^ 3.

Step-by-step explanation:

we are given 12 cm

As we know formula of volume of cube = s ^3 ( side * side * side ) So = 12 * 12* 12 = 1728 cm ^ 3.

Find the Volume cylinder (8cm) (12cm) h = 8cm r = 12cm h = 8 cm r = 12 cm. The volume of a cylinder is equal to the area of the base πr2 π r 2 times the height. π⋅(radius)2 ⋅(height) π ⋅ ( r a d i u s) 2 ⋅ ( h e i g h t) Substitute the values of the radius r = 12 r = 12 and height h = 8 h = 8 into the formula to find the volume of the cylinder

The cost of 200 rectangular pieces of canvas given its dimensions is $36.

The first step is to determine the area of one of the rectangular pieces. A rectangle is a two-dimensional quadrilateral with four right angles.

Area of a rectangle = length x width

6 X 4 = 24 in²

The next step is to determine the area of the 200 rectangular pieces.

Area of the 200 rectangular pieces = 200 x 24in² = 4,800 in²

The last step is to determine the cost of the 200 rectangular pieces.

Total cost = total area x cost per squared inches

The given figure is;

It is given that :

The measurements of angles 1 and 3 are the same.

The measurement of angle 2 equals 110°.

PART A:

Since, angle 1 , 2 and 3 are lie at the same point on the same line

Thus, from the property of angle on a line

Sum of all angles on a strainght line at a point is equal to 180 degree

thus;

Angle1 + Angle2 + Angle 3 = 180

Angle 1 + Angle 2 + Angle1 = 180 {Angle1 = Angle 3, given}

2(Angle 1) + Angle 2 = 180

2 (angle 1) + 110 = 180 {Angle 2 = 110, given}

2(Angle 1) = 180 -110

2(Angle 1) = 70

Angle 1 = 70/2

Angle 1 = 35

Since, angle 2 = 110

The sum of angle 1 and 2 is 110 + 35

Sum of angle 1 and 2 = 145

PART B:

From the properties of the rectangle;

All the angles of a rectangle are 90°

In the given rectangle;

Thus, in the triangle form by the angle3, 4 and the right angle

Sum of all angles in a triangle is equal to 180

Angle 3 + Angle 4 + 90 = 180

35 + Angle 4 + 90 = 180

Angle 4 + 125 = 180

Angle 4 = 180 - 125

Angle 4 = 55

If the line is parallel to y = -3/4 x + 1/4 then the slope is -3/4

the form of an equation is y = mx +b

In this case m = -3/4

Using the point given (4, -2) we will find the value of b:

y = mx + b

y = -3/4 x + b

Using the values of the point (4, -2).... x = 4 and y = -2

-2 = (-3/4)(4) + b

Solving for b:

-2 = -3 + b

-2 + 3 = b

1 = b

b = 1
