A rectangular garden is 17 feet wide. Its length is 3 feet more than twice the width. What is the area of the garden?

Answer:

c

Step-by-step explanation:

Option (C) No; because x and y could be additive inverses of each other is correct.

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

It is given that:

The expression is x + y

The expression can be defined as the combination of constants and variables with mathematical operators.

If x + y is rational, must x and y each can be or cannot be rational because x and y could be additive inverses of each other.

As we know, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

Thus, option (C) No; because x and y could be additive inverses of each other is correct.

To find the population of Smallville and population density per square mile, divide the total population by the area of the town.

Explanation:

The population of Smallville:

Population of Smallville: 72450

Area of Smallville: 5 miles x 1 mile = 5 square miles

Population density in Smallville:

Population density = Population / Area = 72450 / 5 = 14490 people per square mile

To scale down Tom's photo with the original dimensions of 20 cm by 30 cm to a width of 5 cm, the new length should be 7.5 cm. This is calculated using a proportion that maintains the original aspect ratio.

To determine the new length that a photo should be when scaling down, we will maintain the ratio of the original width to the original length. Tom's photo has a width of 20 centimeters and a length of 30 centimeters. If he wants to reduce the width to 5 centimeters, we calculate the new length by setting up a proportion and solving for the missing value:

We set up the following proportion:
20/5 = 30/new length

To solve for new length, we cross-multiply:
(20) * (new length) = (5) * (30)

Then,
new length = (5 * 30) / 20

So,
new length = 150 / 20 = 7.5

Therefore, the new length that Tom should have for his wallet-sized photo is 7.5 centimeters when the width is 5 centimeters.

The lines j' and k' are parallel lines.

                Option: B is the correct answer.

We are given Line j ans Line k such that both are parallel to each other.

Now as we know that the translation transformation just change the position of the location but does not changes it shape.

As both the lines were parallel to each other so on translating both of them they just shifted some units to the right but the behavior remains the same.

Also, from the figure attached to the answer we may observe that the two lines are parallel to each other as the distance between the two lines at each point is constant.

            Hence, the correct answer is:

                       Option: B

Answer: x = 9 (choice D)

Assuming this is a geometric kite, then this means that triangle ABD is a reflection over the line BD to get triangle BCD. Furthermore, this points to AB and BC being the same length

AB = BC

3x - 5 = 22 .... substitution

3x - 5+5 = 22+5 .... add 5 to both sides

Answer:

The speed of the car is 42 miles per hour

Step-by-step explanation:

Step 1:

(Blank) x s = (Blank)

Let us evaluate this. Something times s miles per hour is going to gives us? 126 miles. So, our second blank would be 126 since that's our total:

(Blank) x s = 126

Step 2:

On the other hand, our first blank would be 3. Why? Because that's the amount of time it takes us to go 126 multiplied by s miles per hour; Our new equation is:

3 x s = 126

Step 3:

We can simplify this equation to:

3s = 126

Step 4:

We now have a one step equation. Divide each side by 3 to get s by itself.

[tex]\frac{3s}{3} =\frac{126}{3}[/tex]

Step 5:

We end up getting:

s = 42

That means that the car is traveling at 42 miles per hour. If the car continues at that rate for 3 hours, the car would have traveled 126 miles.

Hope this helps!

Answer:

3 X S = 126

Step-by-step explanation:

because the variable (s) is speed then we must know that 126 is tyhe total that it is driving in 3 hours so 3 time S is 126

Answer:

184.85 square mm

Step-by-step explanation:

The area of a sector of a circle is [tex]\frac{1}{2} r^{2} \theta[/tex], where r is the radius and [tex]\theta[/tex] is the angle in radians subtended by the arc at the centre of the circle.

Since, diameter = 40.6 mm

So, radius(r)=20.3 mm and  [tex]\theta[/tex]=[tex]\frac{2 \pi}{7}[/tex] radians

So, area of sector= [tex]\frac{1}{2} r^{2} \theta[/tex]

=[tex]\frac{1}{2} (20.3)^2 (\frac{2 \times 3.14}{7})[/tex]

=184.85 square mm

The area of the sector using given data is equal to 184.96 mm².

The area of a sector with a central angle of 2π7 radians and a diameter of 40.6 mm.

To solve this, we need to find the radius of the circle, which is half the diameter, and then use the formula for the area of a sector, which is ½ ×r² × θ, where θ is the angle in radians.

First, find the radius: r = ½ × diameter = 0.5 × 40.6 mm = 20.3 mm.

Then, substitute the values into the formula for the area of a sector:

Area = ½ × (20.3 mm)² × (2π7)

        = 1/2 × (20.3)² × (2 × 3.14 /7)

        = 1/2 × 412.09 × 0.89714

        = 184.96 mm²

Rounded to the nearest hundredth, the area of the sector is 184.96 mm².

The number of bags that can be filled completely is 105 and the 3 rocks will be left over.

Division is the process of dividing a number by a given number.

Given that, the number of rocks is 1578 and the number of rocks in each bag is 15.

To find the number of bags, divide the number of total rocks by the number of total rocks in each bag:

1578/15

= 105.2

≈ 105

Now, the number of rocks in 105 bags is:

105 ×15

= 1575

So, the number of rocks left is:
1578 - 1575

= 3

Hence, the number of bags that can be filled completely is 105 and the 3 rocks will be left over.

We are given that AB ≅ CB and AD ≅ CD.

We know that BD ≅ BD, so ΔABD ≅ ΔCBD by SSS.

Then ∠1 ≅ ∠2 by CPCTC; and ∠3 ≅ ∠4, also by CPCTC.

Since ∠1 ≅ ∠2, BD is the bisector of (∠1+∠2) = ∠ABC.

Since ∠3 ≅ ∠4, BD is the bisector of (∠3+∠4) = ∠ADC.

From (5), we know BD is the angle bisector of ∠ABC. ΔABC is isosceles, so the bisector of the apex angle is also an altitude and median. That is, point M on BD and AC must be the midpoint of AC by the definition of a median.

Answer:

Toy Cars=6 and total spending by Mr.Lee=$156

Step-by-step explanation:

Let us first consider

Number of Airplanes=A Cars=C and Trains=T

Now how to start with the problem ? Just start reading it step by step. First statements says that The number of airplanes is 2/3 of The number of cars.

Now how to convert it into an mathematical expression?

here the word "=" is of most important, The number of airplanes "is" whenever you encountered "is" just place a "="

so the first statement can be converted into mathematical expression as,

A=2/3*C  (The number of airplanes is 2/3 of The number of cars.)

Now as per the second condition we can write it in mathematical form as,

C=3/5*T (The number of cars is 3/5 the number of trains).

and the third condition as,

C=3/5*T (The number of cars is 3/5 the number of trains).

Now , we have expressed the statements in mathematical expressions. we have three expressions.

Now It is also given that total number of Toys=20 so we can write it as,

A+C+T=20. ............(1)

Till now we have expressed everything in the question in mathematical form.

now for solving such type of question we need to express the expression giving total in a single entity, expressed it in terms of Airplanes,Cars or Trains,

here we are expressing it in terms of Cars so we can rewrite it (1) as,

2/3*C+C+5/3*C=20 (A=2/3*C and C=3/5*T so T=5/3*C)

by solving this we will get C=6

Total number of car toys, answer of first part

now put this value of C in expression 1,

2/3*C+C+T=20

so the value of T will be 10. T=10

and the total is toys are 20 so 20-10+6=4

Means Airplanes are 4.

Now the cost for each toy is.

A=$12,C=$8 and T=1/2 A i.e T=$6.

So the total cost would be,

4*12+6*8+10*6=$156

$156 answer of second part

I Hope this will help you to solve such kind of Problems.

Mr. Lee buys 6 toy cars for his store. The total cost for all the toys he purchased is $156. This includes the cost of toy airplanes, cars, and trains, with each toy tailoring a specific price.

The student wants to know how many toy cars Mr. Lee bought and the total cost of all toys he purchased for his store. We start with the relationships provided: the number of airplanes is 2/3 the number of cars, and the number of cars is 3/5 the number of trains. We also know that the total number of toys is 20. Let A be the number of airplanes, C be the number of cars, and T be the number of trains. So, we have A = (2/3)C and C = (3/5)T.

From these ratios, we can express airplanes and trains in terms of cars: A = (2/3)C, T = (5/3)C. The equation A + C + T = 20 becomes (2/3)C + C + (5/3)C = 20. Simplifying this, we get (10/3)C = 20, so C = 6. Thus, Mr. Lee buys 6 cars. The number of airplanes, A = (2/3) * 6 = 4, and the number of trains, T = 20 - A - C = 20 - 4 - 6 = 10.

Now let's calculate the total cost. Each toy airplane costs $12, each toy car costs $8, and each toy train costs half as much as an airplane, which is $6. The total cost is 4 airplanes * $12 + 6 cars * $8 + 10 trains * $6, which equals $48 + $48 + $60, resulting in a total of $156 spent by Mr. Lee.

Answer:

Area of triangle is 25.

Step-by-step explanation:

We have been given an isosceles right triangle

Isosceles triangle is the triangle having two sides equal.

Figure is shown in attachment

By Pythagoras theorem

[tex]BC^2=AC^2+AB^2[/tex]

AD is altitude which divides the triangle into two parts

DC=5 implies BC =10 since D equally divides BC

Let AC=a implies AB=a being Isosceles

On substituting the values in the Pythagoras theorem:

[tex]10^2=a^2+a^2[/tex]

[tex]100=2a^2[/tex]

[tex]\Rightarrow a^2=50[/tex]

[tex]\Rightarrow a=\pm5\sqrt{2}[/tex]

WE can find area of right triangle by considering height AB and AD

Area of triangle ABC is:

[tex]\frac{1}{2}\cdot BC\cdot AD[/tex]     (1)

[tex]\Rightarrow \frac{1}{2}\cdot 10\cdot AD[/tex]

And other method of area of triangle is:

[tex]\frac{1}{2}\cdot AB\cdot BC[/tex]       (2)

Equating (1) and (2) we get:

[tex]\frac{1}{2}\cdot 10\cdot AD=\frac{1}{2}\cdot a\cdot a[/tex]

[tex]\Rightarrow AD=\frac{a^2}{10}[/tex]

[tex]\Rightarrow AD=\frac{50}{10}=5[/tex]

Using area of triangle is: [tex]\frac{1}{2}\cdot BC\cdot AD[/tex]

Now, the area of triangle ABC=[tex]\frac{1}{2}\cdot 5\cdot 10[/tex]

[tex]\Rightarrow 25[/tex]

Answer:

336$

Step-by-step explanation:

Given: Each invitation costs a total of 3$.

Given: There were a total of 112 invitations made.

So, the question is asking you to find the total amount spent making the invitations. To do so we need to find the product/sum. Product in mathematical terms is used to describe the answer to a multiplication problem. Sum on the other hand is used to describe the answer to an addition problem. Now you could just add, but multiplication is a better way of simplifying the problem. So instead of saying 3 + 3 + 3 + 3.. or 112 + 112 + 122, we say 122 x 3 = x.

Now that we've created the equation, we can find the answer.

122 x 3 = 336

Answer: Andri spent 336$ on materials for her invitations.

To find the sales tax on a $60 bill with a 5% rate, convert the percentage to a decimal (0.05) and multiply by the total amount ($60). The sales tax is $3.

The sales tax on a total bill can be calculated by converting the percentage rate of the sales tax into a decimal and then multiplying it by the total amount of the bill.

In this case, the total cost is $60 and the sales tax rate is 5%. First, convert 5% into a decimal by dividing it by 100, which gives us 0.05. Then, multiply this decimal by the total bill amount to find the amount of sales tax. The calculation would be as follows:

$60 × 0.05 = $3

Therefore, the sales tax for a $60 bill at a 5% rate is $3.
