Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Cost for 5 weeks i.e. 15 classes = $108

Cost of per class is given by

[tex]\frac{108}{15}=7.2[/tex]

Cost for 8 weeks i.e. 24 classes = $125

Cost of per class is given by

[tex]\frac{125}{24}=5.21[/tex]

Amount of saving of per class by taking the 8 week class is given by

[tex]7.2-5.21=\$1.99[/tex]

Hence, Option 'C' is correct.

The decimal form of the given percent 203% is 2.03

A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction. The word "percent" means "per hundred." So, whenever you see a number with a percent sign (%), you can imagine it as a fraction,

Percent is from the Latin adverbial phrase per centum meaning “by the hundred.” The Latin phrase entered English in the 16th century.

Example: 10% means 10 out of every 100. So if 10% of 500 people have ice cream, then 50 people have ice cream.

Given that, what is decimal form for the 203 percent,

Since, the percent is any number in its 100th part,

Therefore, 203% = 203/100

Since, it is 100 in the denominator,

The decimal will be put after two digits in the numerator,

Therefore,

203% = 203/100 = 2.03

Hence, the decimal form of the given percent 203% is 2.03

When a system has one answer or in other words, the graphs of the equations intersect one time, the system is called a consistent system of linear equations and therefore the equations are independent.

When a system has no solution meaning, the graphs of the equations don’t interconnect at all, the system is known to be an inconsistent system of linear equations and the equations are independent.

So therefore, the answer is yes.

Answer: 704 feet

Step-by-step explanation: speed of car is V= 60 miles per hour

First convert the speed from miles per hour to feet per second .

[tex]V=\frac{60\times 5280}{60\times 60} \frac{ft}{s} = 88 \frac{ft}{s}[/tex]

Now Length of tunnel , L= speed of car x time taken

Therefore [tex]L=88\times 8 feet=704 feet[/tex]

The time it takes the rock to reach the canyon floor is after 3.99seconds

The intercept is the point where the axis is equal to zero. Give the quadratic equation that represents the height h (in feet) of an object t seconds after it is dropped expressed as:

h = -16t² + 255

The rock reaches the ground when h(t) = 0. Substitute

h = -16t² + 255

h = -16t² + 255 = 0
16t² = 255
t² = 255/16
t² = 15.9375

t = 3.99seconds

Hence the time it takes the rock to reach the canyon floor is after 3.99seconds

The first factor has a degree of 7, the second has a degree of 6, and the third has a degree of 5. The product has a degree of 7, the highest among them.

To determine the degree of each polynomial in the expression[tex]2a^7 - 16a^6 + 18a^5[/tex], we need to understand that the degree of a polynomial is the highest exponent of the variable in that polynomial.

The first factor is[tex]2a^7[/tex]. Here, the highest exponent of the variable 'a' is 7. So, the degree of the first factor is 7.

The second factor is[tex]-16a^6[/tex]. In this case, the highest exponent of 'a' is 6. So, the degree of the second factor is 6.

The third factor is [tex]18a^5[/tex]. Here, the highest exponent of 'a' is 5. So, the degree of the third factor is 5.

Now, to find the degree of the product of these three factors when added together, we need to find the highest degree among them. In this case, the highest degree is 7 (from the first factor). Therefore, the product has a degree of 7.

In summary:

The first factor has a degree of 7.

The second factor has a degree of 6.

The third factor has a degree of 5.

The product has a degree of 7.

These degrees reflect the highest power of 'a' in each term of the polynomial expression.

Final answer:

To confirm that a transformation is not a rigid motion, use a protractor to check for any changes in angles within a shape post-transformation. If the angles have changed, the transformation is not rigid. Corresponding side length changes further confirm this.

Explanation:

To confirm that a transformation is not a rigid motion using a protractor, you must look for changes in the shape's size or the angles between any two adjacent sides. A rigid motion, also known as an isometry, will preserve distances and angles between all points on a shape. Therefore, if after a transformation, using a protractor shows that the angles within the shape have changed, or that the corresponding sides are not congruent, then the transformation is not a rigid motion.

For example, if you have a triangle and apply a transformation, such as dilation or shearing, the new angles can be measured with a protractor. If they are different from the original triangle's angles, this confirms the transformation was not a rigid motion. Additionally, if the distances between corresponding points on the figure have changed, which you can measure with a ruler, this also confirms that the transformation is not rigid.

To find two numbers a and b whose sum a + b is 0 and whose difference a - b is 2, we can set up a system of equations and solve for the values of a and b.

To find two numbers a and b whose sum a + b is 0 and whose difference a - b is 2, we can set up a system of equations:

a + b = 0

a - b = 2

We can solve this system by adding the two equations:

(a + b) + (a - b) = 0 + 2

2a = 2

a = 1

Substituting the value of a back into one of the equations, we find that b = -1.

Therefore, the two numbers are 1 and -1.

Step-by-step explanation:

Answer-

Area of the kite is 14.0 sq.units

Solution-

[tex]\text{Area}_{WXYZ}=\text{Area}_{WXY}+\text{Area}_{WZY}[/tex]

From the graph, in the triangle WXY

Base = WY=4 units,

Height = 3 units

[tex]\text{Area}_{WXY}=\dfrac{1}{2} \cdot base\cdot height=\dfrac{1}{2} \cdot 4\cdot 3=6\ sq.unit[/tex]

From the graph, in the triangle WZY

Base = WY=4 units,

Height = 4 units

[tex]\text{Area}_{WZY}=\dfrac{1}{2} \cdot base\cdot height=\dfrac{1}{2} \cdot 4\cdot 4=8\ sq.unit[/tex]

[tex]\therefore \text{Area}_{WXYZ}=6+8=14\ sq.units[/tex]

Option (b) 4(3-x)+6x=3x+12+2x is the equation that has the solution x = all real numbers because it simplifies to an identity, which is true for any value of x.

Among the given equations, the one that has the solution x = all real numbers is essentially an identity, meaning that for any value of x you plug into the equation, the equation will hold true. To determine which equation is an identity, each equation must be simplified.

Let's take option (b) as an example:

4(3−x)+6x=3x+12+2x

4∙3 - 4∙x + 6∙x = 3∙x + 12 + 2∙x

12 - 4∙x + 6∙x = 3∙x + 12 + 2∙x

12 + 2∙x = 5∙x + 12

12 - 12 + 2∙x - 2∙x = 5∙x - 2∙x + 12 - 12

0 = 3∙x - 3∙x

After simplifying, we end up with 0 = 0, which is an identity and is true for all values of x, hence this is the equation where x is all real numbers.
