Answer:

a)  See the attachment for the completed Venn diagram.

b)  The number of people who liked to watch television only is 20.

c)  The total number of people who took part in the survey was 200.

Step-by-step explanation:

Draw a Venn diagram with two overlapping circles.

Label one circle "Radio" and the other circle "TV".

Given that 50 people like to listen to the radio but not like to watch television, place the number 50 in the part of the radio circle that does not overlap the TV circle.

Given that 120 people like to listen to the radio, and 50 people like to listen to the radio but not like to watch television, then the number of people who like to listen to the radio and watch tv is:

Therefore, place the number 70 in the part where the two circles overlap.

Given that 110 people don't like to watch television, and 50 people like to listen to the radio but not like to watch television, then the number of people who don't like to listen to the radio or watch television is:

Therefore, place the number 60 in the area outside the two circles.

Given that 80 people don't like to listen to the radio, and 60 people don't like to listen to the radio or watch television, then the number of people who like to watch the television only is:

Therefore, place the number 20 in the part of the TV circle that does not overlap the radio circle.

Now the Venn diagram has been completed, we can find the total number of people who took part in the survey by adding all the numbers in the Venn diagram:

Therefore, there was a total of 200 people who took part in the survey.

The equation 2(x - 4) = 2x - 8 has infinitely many solutions.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given equation is 2(x - 4) = 2x - 8.

Solving this,

Using the distributive property, a (b + c) = ab + ac, 2(x - 4) = (2 × x) - (2 × 4).

Substituting in the original equation,

(2 × x) - (2 × 4) = 2x - 8

2x - 8 = 2x - 8

2x - 2x = -8 + 8

0 = 0

Right hand side and left hand side are equal if we put any value for x.

So it has infinitely many solutions for x.

With given features we can definably say that Both triangles are congruent under ASA Criteria.

A triangle is a closed polygon made up of three line segments that intersect at three different angles.

If the sides and angles of two triangles are the same length, the triangles are said to be congruent. As a result, two triangles can be superimposed side by side and angle by angle. Congruence is the term used to describe the relationship between an object and its mirror image. When two objects or shapes superimpose on one another, they are said to be congruent. They are identical in terms of shape and size. Line segments of the same length and angles of the same measure are congruent in the context of geometric figures.

Given far opposites angle are same = 25°

Given intersected line makes equal line

Intersecting angles are equal due to vertically opposite angle theorem.

The length of the radius of the circle is 7.5 inches.

The radius formula is easily obtained by halving the circle's diameter. The line segment created when we join a point on a circle's circumference to its exact center is referred to as the ring's radius. The radius of a circle is the separation between its centre and circumference. Always, the diameter is twice the radius. As a result, the formula is created by multiplying the diameter by two.

Given that the diameter of the circle is 15 inches.

The radius of the circle is half the measure of the diameter.

That is,

R = d/2

R = 15/2

R = 7.5 inches

The customer had a 3-hour repair when paying $96 without a coupon.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

With a coupon, the customer paid $66 for a 3-hour repair.

The coupon gives a 40% discount on the inspection fee, so let's call the original inspection fee "x". Then the customer paid 0.6x + 14*3 = $66.

Solving for x, we get x = $30.

Without a coupon, the customer paid $96.

We want to find out how many hours of repair were done for $96.

Let's use a similar equation to solve for the number of hours:

Let's call the number of hours "h". Then the customer paid 30*0.6 + 14h = $96.

Solving for h, we get h = 3.

The linear equation that gives the dollar value V of the product in terms of the year t is V = - $5600t + $344,000.

V(t) is a function of t that expresses the value in the year 2000+t.  

We know that the decrease is $5600 per year.

So,

V(t) = -$5600t + c

With the root values 6 and 8 the quadratic equation is x² - 6x +8 = 0.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

The roots of the quadratic equation are -

HCF of smallest prime number, LCM of smallest composite number

The smallest prime number is 2.

So, the HCF of 2 is 2.

The smallest composite number is 4.

So, the LCM of 4 is 4.

If m and n are the roots of a quadratic equation ax² + bx + c = 0, then the sum of the roots is (m+n) and the product of the roots is (mn).

And then the quadratic equation becomes x² - (m+n)x +mn = 0.

So, here m = 2 and n = 4.

The sum of roots is -

(m + n) = (2 + 4) = 6

The product of roots is -

(mn) = (2 × 4) = 8

So, the quadratic equation is x² - 6x +8 = 0.

Therefore, the equation is x² - 6x +8 = 0.

The distance from point A to point B is 1496 ft.

Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.

Given that, a boat is at point A which at 724 ft distance from a lighthouse making an angle of elevation to the lighthouse’s beacon-light of 16°, when moved to some distance B making an angle of elevation to the lighthouse’s beacon-light of 5°, we need to find the distance from point A to point B.

Refer to the figure attached,

The whole scene is creating two right triangles, rt Δ CDA and rt Δ CDB

Using the trigonometric functions, in rt Δ CDA,

We have,

tan 16° = CD/DA

CD = tan 16° × 724

CD = 207.6

Therefore, the height of the lighthouse is 207.6 ft

Now,

tan 5° = CD/DB

DB = CD / tan 5°

DB = 2373

The distance between A and B = DB-DA = 2373 - 724 = 1496

Hence, the distance from point A to point B is 1496 ft.

120 calories make up one cup amount of calories. Three cups of the cereal have 360 calories in them.

1. Determine how many calories are in a cup: 120 calories are in 3/4 cup; 3/4 cup is 120 calories.

2. Determine how many calories are in 3 cups: 3 cups at 120 calories each equals 360 calories.

You must divide the total amount of calories in a serving of 3/4 cup by 3/4 cup to determine the unit rate for calories per cup of a certain cereal. In this instance, a serving of the cereal that is 3/4 cup in size has 120 calories. As a result, 120 calories are the number of calories in a cup. You must multiply the unit rate for calories per cup (120 calories) by 3 cups to see how many calories are in 3 cups of cereal. This indicates that there are 360 calories in 3 cups of the cereal.

Answer: The total amount paid for shoes = $63.75

Step-by-step explanation:

The original price of the shoes = $ 80

Sale Discount = 25 %

So, the discount offered = 25 % of 80 = 20

So, the Discounted Price  = Marked price - discount

= $ 80 -$ 20 = $ 60

Now, we need to calculate the sale tax of 6.25 % on $ 60.

Also, we know that  Sales Tax = Sales Tax rate x Sale Price

= $ 60 x 0.0625  = $ 3.75

Total Cost = Sale Price + Sales Tax

=  $ 60 + $ 3.75  = $63.75

Hence, the total amount paid for shoes = $63.75 included sales tax
