You spend $30.40 on 4 CDs. Each CD costs the same amount and is on sale for 80% of the original price. a. Write and solve an equation to find how much you spend on each CD. Let p represent the price you pay for each CD. Equation: =30.40 You spent $ on each CD. Question 2 b. The next day, the CDs are no longer one sale. You have $25. Will you be able to buy 3 more CDs? No, you will not be able to buy 3 more CDs. Question 3 c. Explain your reasoning for part (b). Each CD costs $ at the regular price, so 3 CDs would cost $ .

Answers

Answer:

$7.6 ;

No, you will not be able to buy 3 more CDs

$9.5

$28.5

Step-by-step explanation:

Given that :

Cost of 4 CDs = $30.40

Cost per CD is equal

Sale price = 80% of original price

Price p per CD:

Cost of 4 CDs / number of CDs

$30.40 / 4

= $7.6

No, you will not be able to buy 3 more CDs

If x = original price

80% of x = 7.6

0.8x = 7.6

x = 7.6 / 0.8

x = $9.5

$9.5 * 3 =$28. 5

Hence, $25 can't buy 3 CDs the next day (28.5 > $25)

In ΔUVW, u = 44 inches, ∠W=56° and ∠U=117°. Find the length of v, to the nearest inch.

Answers

Answer:

The length of v is 6 inches

Step-by-step explanation:

Here, we want to calculate the length of v to the nearest inch

The best way to go about this is to use the sine rule

But before we proceed, we need the measure of angle V

Mathematically, since we have a triangle

W + U + V = 180

This is the sum of angles in a triangle

56 + 117 + V = 180

V = 180-56-117

V = 7 degrees

so we proceed to use sine rule to get the length of v

Mathematically;

v/Sin V = u/Sin U

Thus;

v/sin 7 = 44/sin 117

v = 44sin 7/sin 117

v = 6.018

This is approximately 6 inches

Find the coordinates of the point where y-4x=1 crosses the y axis

Answers

Answer:

(a) (-1/4,0)

(b) k = (10-c)/2

Step-by-step explanation:

(a) A point passing through the y-axis is the same as finding the y-intercept.

[Move terms to right-hand side; y = mx + b form]

y = 4x + 1

[Find x, when y = 0]

0 = 4x + 1

-1 = 4x

-1/4 = x

At x = -1/4, y = 0 therefore the point: (-1/4,0) crosses the y-axis.

(b) To find the value of k in (k,10), we need to find x. Given y= 10 x=k c=constant

[Find x by plugging in known values]

Using y = 2x + c,

10 = 2k + c

10 - c = 2k

(10-c)/2 = k

Find the circumference and the area of a circle with radius 7ft .
Use the value 3.14 for pi, and do not round your answers. Be sure to include the correct units in your answers.

Answers

Answer:

C=43.96 ft.

A=153.86 ft.^2

Step-by-step explanation:

for circumference, use C=2πr

for area, use A=π[tex]r^{2}[/tex]

The circumference and the area of a circle with radius 7 feet are 43.96 feet and 153.86 square feet, respectively.

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.

And the general formula of the circle,

(x – h)²+ (y - k)² = r²,

where (h, k) is the center and r is the radius of the circle.

Given:

A circle with radius 7 feet.

Then the circumference of the circle,

= 2πr

= 2(3.14)(7)

= 43.96 feet.

The area of the circle,

= πr²

= (3.14) (49)

= 153.86 square feet.

Therefore, circumference is 43.96 feet and area is 153.86 square feet.

Kate is 4 years older than Bob. If the sum of their ages is 28, what are the ages of
Kate and Bob?

Answers

Bob is 24 Kate is 28

Answer:

Kate is 16, Bob is 12

Step-by-step explanation:

Since Kate is 4 years older than Bob, Kate's age is represented by the following equation:

B+4=K

Bob's age is just B

Now, the sum of their ages is 28, which means we add Kate's and Bob's age:

Instead of writing K+B=28, we would write the equation with the same variable:

B+4+B= 28

(B+4= Kate's age)

add like terms

2b+4=28

subtract 4 from both sides

2b=24

divide by 2

b=12

12 is Bob's age and to find Kate's age, we add 4

Kate is 16.

Emma is 10 years old. she asked her father how old he is. her father answered, "when you are my age I will be 70." how old is Emma's father.

Answers

Answer:

Step-by-step explanation:

Emma age: yE = 10 + x (x is timeline)

Father age: yF = A + x (x is timeline, A is Father age today)

in time x1: Emma will be A years old, and Father will be 70 years old.

yE (x1) = 10 + x1 = A

yF (x1) = A + x1 = 70

System of equations with unknown values: x1 and A.

substract equation 1 - equation 2:

10 - A = A - 70 ⇒ 80 = 2A ⇒ A = 40

So, father is 40 years old now

Emma's father is 40 years old

Let the age of Emma father be y

Age of emma = 10 years

In x years time;

Emma age will be 10 + xFathers age will be y + x

If in x1 years time, Emma will be y years old and his father will be 70 years old

Emma age: yE = 10 + x (x is timeline)

Emma's current age will be 10 + x = yHis father;s current age will be y + x = 70

Solving both equations simultaneously;

10 - y = y - 70

10+70 = y + y

80 = 2y

2y = 80

y = 80/2

y = 40 years

Hence Emma's father is 40 years old
