the length of a rectangle playground in a scale drawing is 12 inches. if the scale is 1 inch = 10 feet, what Is the actual length. please show me how you got the answerrr

Answer:

3x

Step-by-step explanation:

If you have 2x, that would mean there is 1x and 1x. T

he question asks what 2x+2x+1x is, and since all three have the same variable you can just add the coefficient.

The coefficients are 1, 1, and 1 since they are in front of the variable.

The variable is x.

Therefore, since 1+1+1=3, your answer is 3x.

Answer:

Choice C.

Step-by-step explanation:

Kermit likes :

15 tea bags

every 2 liters

Peggy:

90 tea bags

12 liters

You would simplify it by dividing 90 by 15, equaling 6. And 12 divided by 2, also equaling 6. Which would mean they are equal and Peggy's tea is exactly like Kermit's favorite iced tea.

Answer:  The correct choice is

Choice (C)  It is just right.

Step-by-step explanation:  Given that Kermit's favorite iced tea is made with 15 tea bags in every 2 liters of water and Peggy made a 12 liter batch of iced tea with 90 tea bags.

We are to select the correct choice that describes the thinking of Kermit about Peggy's Iced tea.

The ratio of quantity of water and number of tea bags in Kermit's favorite iced tea is given by

[tex]R_k=2:15.[/tex]

And the ratio quantity of water and number of tea bags in Peggy's iced tea is given by

[tex]R_p=12:90=\dfrac{12}{90}=\dfrac{2}{15}=2:15.[/tex]

Since the ratio of water and number of tea bags in Peggy's iced tea is same as that in Kermit's favorite iced tea, so

Kermit will think that Peggy's iced tea is just right.

Choice (C) is CORRECT.

Answer:

a) UXW = 78        b) UWY = 48         c)  WZX = 48          d) XYZ = 42

Step-by-step explanation:

There are many ways you can do this, but I'll just describe one for each.

a) Angle YWV is vertical to XWZ, so they are congruent. Angle XWZ is an alternate interior angle with angle UXW, so UXW = 78.

b) All the angles that revolve around point W must add up to 360. We already know 4 angles due to vertical angles, so 78 + 78 + 54 + 54 = 264.

360 - 264 = 96.   There are two angles left, and since they are vertical they must be congruent. 96/2 = 48, so angle UWY is 48 degrees.

c) We already know that the angle vertical to UWY is 48, so WZX is also 48 degrees because they are alternate interior angles.

d) Angle UWY is 48 degrees and angle WUY is 90 degrees because of the perpendicular line. Now we can find XYZ, the remaining angle.

90 + 48 = 138.           180 - 138 = 42.          So XYZ = 42 degrees.

I hope this helped. I'm open to any questions you may have. :)

Answer:

a) UXW = 78 degrees

b) UWY = 48 degrees

c) WZX = 48 degrees

d) XYZ = 42 degrees

Step-by-step explanation:

Apply rules and theorems:

Angles in a triangle add up to 180 degrees.

Angles on a straight line add up to 180 degrees.

Right angles are 90 degrees.

Vertically opposite angles are equal.

With these we can solve for the angles.

Answer: [tex]25\pi\ ft^2[/tex] (First option)

Step-by-step explanation:

The formula for calculate the area of a circle is the one shown below:

[tex]A=r^2\pi[/tex]

Where r is the radius of the circle.

XY is the diameter. Then the radius is:

[tex]r=\frac{10ft}{2}\\r=5ft[/tex]

Substitute values into the formula shown above. Therefore, the area of the circle is:

[tex]A=(5ft)^2\pi \\A=25\pi\ ft^2[/tex]

Answer:

The correct answer is first option 25pi ft2

Step-by-step explanation:

Formula

Area of circle = πr²

r - Radius of circle

To find the area of given circle

Here XY = 10 ft

XY is the diameter of given circle

Radius r = Diameter/2 = 10/2 = 5 ft

Area = πr² = π5² = π x 5 x 5 = 25π ft²

Therefore area of given circle is 25π ft²

The correct answer is first option.

Answer:

Step-by-step explanation:

We have:

h = 40 ft

2r = 20 ft → r = 10 ft

Substitute to the formula of a Surface Area of a cylinder:

[tex]SA=2\pi r^2+2\pi rh[/tex]

[tex]SA=2\pi(10^2)+2\pi(10)(40)=2\pi(100)+2\pi(400)\\\\=200\pi+800\pi=1,000\pi\ ft^3\\\\\pi\approx3.14\to SA\approx1,000(3.14)=3,140\ ft^3[/tex]

Answer:

96°

Step-by-step explanation:

so we are given two angles, we can use the two angles that were given to find the angles inside the triangle (2 of them)

then once we find those two angles in the triangle, we can use those to find the third angle

then we can figure out what x is

so both a straight line and a triangle are 180°

angle 1: 180°-134° = 46°

angle 2: 180°- 130° = 50°

now we add the two angles together: 46° + 50° = 96°

one triangle = 180°

180° - 96° = 84° = angle 3

now we can find x by subtracting 84° from 180°

180°-84° = 96°

Answer:

x = 96 degrees

Step-by-step explanation:

As you know the sum of a set of exterior angles is 360 degrees

so

x + 130 + 134 = 360

x + 264 = 360

x = 360 - 264

x = 96

Answer:

[tex]\large\boxed{3\dfrac{18}{19}}[/tex]

Step-by-step explanation:

[tex]\text{First step:}\\\text{Convert the mixed number to the improper fractions:}\\\\7\dfrac{1}{2}=\dfrac{(7)(2)+1}{2}=\dfrac{15}{2}\\\\1\dfrac{9}{10}=\dfrac{(1)(10)+9}{10}=\dfrac{19}{10}\\\\7\dfrac{1}{2}:1\dfrac{9}{10}=\dfrac{15}{2}:\dfrac{19}{10}\\\\\text{Dividing by a fraction is the same as multiplying by the inverse of a fraction}\\\\=\dfrac{15}{2}\cdot\dfrac{10}{19}=\dfrac{15}{2\!\!\!\!\diagup_1}\cdot\dfrac{10\!\!\!\!\diagup^5}{19}=\dfrac{15}{1}\cdot\dfrac{5}{19}=\dfrac{75}{19}=3\dfrac{18}{19}[/tex]

First, convert the mixed fractions into improper fractions. Then, turn the division problem into a multiplication problem by utilizing the concept of reciprocal. This gives us 75/19, or about 3.95 in decimal.

We first need to convert the mixed fractions into improper fractions. To do this, we multiply the whole number by the denominator of the fractional part and then add the numerator, placing this sum over the original denominator. This makes 7 1/2 into 15/2 and 1 9/10 into 19/10. The division problem 7 1/2 divided by 1 9/10 simplifies to 15/2 divided by 19/10.

Next, we remember that dividing by a fraction is the same as multiplying by its reciprocal. The reciprocal of a fraction is obtained by swapping the numerator and denominator. So, we change our division problem into a multiplication problem, transforming 15/2 divided by 19/10 into 15/2 * 10/19.

After multiplying these fractions, we get 150/38, which simplifies to 75/19, which is approximately 3.95 when converted to decimal.

Answer:

Step-by-step explanation:

∠6 and ∠7 are Alternate Interior Angles.

The lines l and m are parallel, therefore ∠6 and ∠7 are congruent.

m∠6 = m∠7 → 4x - 15 = x + 30        add 15 to both sides

4x = x + 45          subract x from both sides

3x = 45            divide both sides by 3

x = 15

Answer:

[tex]\angle 6 =45^{\circ}[/tex]

Step-by-step explanation:

We are given that l || m

[tex]\angle 6 = 4x-15[/tex]

[tex]\angle 7 = x+30[/tex]

Since l || m

So, [tex]\angle 6 = \angle 7[/tex] (Alternate interior angles are equal )

So, [tex]4x-15 =  x+30[/tex]

[tex]3x= 45[/tex]

[tex]x= 15[/tex]

[tex]\angle 6 = 4x-15=4(15)-15 = 45^{\circ}[/tex]

So, [tex]\angle 6 =45^{\circ}[/tex]

Let x = - 2

y = - abs(-2)

The absolute command changes - 2 to + 2

y = - abs(2)

y = - 2 because of the minus sign in front of  the absolute value command.

Answer:

4(x-3)(x+6)

Step-by-step explanation:

We factor out the 4 first since all numbers are divisible by 4. That leaves us with x^2+3x-18.

Then we factor this to get (x-3)(x+6).

So the factored form of the equation is 4(x-3)(x+6)

Step-by-step explanation:

The factors of the equation 4x²+12x -72 will be 4(x-3)(x+6).

A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Factor out the 4 first since all numbers are divisible by 4. That leaves us with x² +3x -18.

4( x² +3x -18 ) = 4 ( x² + 6x - 3x -18 )

                      = 4 ( x(x+6) -3 (x + 6)

                      = 4 ( x + 6 ) ( x - 3 )

Hence, the factors are 4 ( x + 6 ) ( x - 3 ).

The mathematical expression for "the product of z, x, and y" can be represented as [tex]\( z \times x \times y \)[/tex].

The mathematical expression for "the product of z, x, and y" can be represented as [tex]\( z \times x \times y \)[/tex]. In this expression, the symbol [tex]\( \times \)[/tex] denotes multiplication, and the three variables [tex]\( z \), \( x \), and \( y \)[/tex] are multiplied together to obtain their product.

This expression succinctly captures the idea of multiplying these three variables. In mathematical terms, a product refers to the result of multiplying two or more numbers or variables.

Therefore, [tex]\( z \times x \times y \)[/tex] represents the outcome of multiplying the values represented by the variables [tex]\( z \), \( x \), and \( y \)[/tex].

This expression provides a clear and concise way to articulate the mathematical concept of the product of three variables.

The product of ( z ), ( x ), and ( y ) is: ( zxy ).

To translate the phrase "the product of ( z ), ( x ), and ( y )" into a mathematical expression, follow these steps:

1. Identify the Variables:

  The variables involved in the expression are ( z ), ( x ), and ( y ).

2. Understand the Operation:

  The term "product" indicates multiplication.

3. Write the Expression:

  To express the product of ( z ), ( x ), and ( y ) mathematically, you simply multiply these variables together.

1. Start with the First Two Variables:

  Multiply ( z ) and ( x ) together.

[tex]\[ z \times x \][/tex]

2.Include the Third Variable:

  Now, multiply the result from the first step by ( y ).

[tex]\[ (z \times x) \times y \][/tex]

3. Simplify the Expression:

  In multiplication, the order in which you multiply numbers does not matter due to the commutative property of multiplication. Therefore, we can drop the parentheses.

[tex]\[ z \times x \times y \][/tex]

The mathematical expression for "the product of ( z ), ( x ), and ( y )" is:

[tex]\[z \cdot x \cdot y\][/tex]

or simply:

[tex]\[zxy\][/tex]

This is the complete mathematical translation of the given phrase.
