Given:

To find:

Answer:

Let's assume that the length is 2x and the width is 1x.

We know that the formula to find the perimeter of a rectangle is as follows:

Perimeter = 2 × (Length + Width)

Substituting the values that we have, into the formula above,

84 = 2 × (2x + 1x)

84 = 2 × 3x

84/2 = 3x

42 = 3x

x = 42/3

x = 14

Since we know the value of 'x', let's use it to find the length and the width.

Length = 2x = 2 × 14 = 28

Width = 1x = 1 × 14 = 14

Since we now know the length and the width, let's find the area of the rectangle.

The formula to find the area of a rectangle:

Area = Length × Width

Substituting the values we have into the formula,

Area = 28 × 14

Area = 392

Therefore, the area of the rectangle is 392 square yards.

Hope it helps. :)

Answer:

(a) Leann is incorrect

(b) For every main dish, there are 3 sides

(c) 6 selections

Step-by-step explanation:

See attachment for complete question

Given

Main Dish: Burger (B), Chicken (C), Pasta (P)

Sides: Apple (A), Fries (F)

Solving (a): Is Leann list correct?

From the question, the list is: BA, BF, CA, CF, PA, PF, AB, FB, AC, FC, AP, FP

This list is incorrect because:

AB is the same BA, BF is the same as FB and so on

Solving (b): Number of sides for each Main dish

From the question:

[tex]Main\ dish = 2[/tex]

[tex]Sides = 3[/tex]

This implies that:

For every main dish, there are 3 sides

Solving (c): Total number of selection

In (b), we have:

[tex]Main\ dish = 2[/tex]

[tex]Sides = 3[/tex]

So: the total is:

[tex]Total = Main\ dish * Sides[/tex]

[tex]Total = 2 * 3[/tex]

[tex]Total = 6[/tex]

Given:

44 cu. cm of wire is drawn into a wire of diameter 2 mm.

To find:

The length of the wire.

Solution:

We know that,

1 cm = 10 mm

1 cu. cm = 1000 cu. mm

We have, a wire of cylindrical shape.

Volume of the wire = 44 cu. cm

                                = 44000 cu. mm

Radius of the wire = 2 mm

Volume of a cylinder is:

[tex]V=\pi r^2h[/tex]

Where, r is the radius and h is the height.

Putting V=44000, [tex]\pi=\dfrac{22}{7}[/tex] and r=2, we get

[tex]44000=\dfrac{22}{7}\times 2^2\times h[/tex]

[tex]44000\times \dfrac{7}{22}=4h[/tex]

[tex]14000=4h[/tex]

Divide both sides by 4.

[tex]\dfrac{14000}{4}=h[/tex]

[tex]3500=h[/tex]

Therefore, the length of the wire is 3500 mm or 350 cm.

Answer:

Yes

Step-by-step explanation:

A triangle is a "right" triangle if its lengths fullfil the Pythagorean theorem:

[tex]a^2+b^2=c^2[/tex]

Here, a and b are the shorter "legs" of the triangle, adjacent to its right angle, while c is the "hypotenuse," the longest side and the one opposite the right angle.

If we call the 1.9 cm and 2.7 cm our legs, the sum of their squares is:

[tex]2.7^2+1.9^2=10.9[/tex] cm

While squaring our hypotenuse gives us

[tex]3.3^2=10.89[/tex] cm

The fact that we measured the triangle's side lengths to 1 decimal point of accuracy means that there's a little margin of error baked into the measurement. The two previous calculations are within 0.01 cm of each other, which is more than close enough, so we can say that yes, this could be a right triangle.

Answer:

Rate = 4%

Step-by-step explanation:

Simple interest = (principal × rate × time) / 100

Principal = $399.00

Rate = ?

Time = 2 years

Interest = $31.92

Simple interest = (principal × rate × time) / 100

31.92 = (399 * x * 2) / 100

31.92 = 798x / 100

Cross product

31.92 * 100 = 798x

3192 = 798x

x = 3192 / 798

x = 4%

Rate = 4%

Answer:

11 1/4

Step-by-step explanation:

Multiply this by three, 3, 6, 9.

3/4, 1 2/4, 2 1/4.

2 + 9 = 11.

11= 1/4 = 11 1/4

Answer:

Max drank 11 1/4 cups of milk today.

Explanation:

Convert the mixed number (3 3/4) to a fraction.  

Then your equation becomes:

15/4 x 3/1 (since he tripled the cups of milk he drank you multiply by 3 which as a fraction is 3/1)

Next:

15/4 x 3/1= 11 1/4!

Answer:

Step-by-step explanation:

True

Answer:

it would be A.

Step-by-step explanation:

10% off means she pays 90% of the original price. (100% - 10% = 90%)

62 x 0.90 = 55.80 the sale price of the dress is $55.80

Now add the tax by multiplying the sale price by 1 + tax rate:

55.80 x 1.0675 = 59.57

She paid $59.57

Answer:

10% off means she pays 90% of the original price. (100% - 10% = 90%)

62 x 0.90 = 55.80 the sale price of the dress is $55.80

Now add the tax by multiplying the sale price by 1 + tax rate:

55.80 x 1.0675 = 59.57

She paid $59.57

Answer:

530.66

Step-by-step explanation:

The computation of the area of the cross section is shown below

Given that

Volume = 9208 m^3

Now let us assume the radius be r

So volume = 4 ÷ 3 πr^3

9202.8 × 3 ÷ 4π = r^3

27,608.4 ÷ 4 × 3.14 = r^3

27,608.4 ÷ 12.56 = r^3

2,198.12 = r^3

r = 13

Now the area of the cross section is

= πr^2

= 3.14 × (13)^2

= 530.66

Answer:

262 square feet

Step-by-step explanation:

The required expression model for the cost of the ramp is y = 2.20x.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Let the area of the ramp be x and the cost to build the ramp be y,

According to the question,
The material Santiago will use to build the ramp costs $2.20 per square foot.

Total cost = 2.20 × area of the ramp

Substitute the variable in the above expression,

y = 2.20x

The above equation represents the equation model for the cost of ramp y for the x square foot area of the ramp.

Thus, the required expression model for the cost of the ramp is y = 2.20x.
