A store pays $110 for a bike. The mark up is 80%. Find the selling price.

Answer: 6.4cm

Step-by-step explanation:

The area of a trapezoid is given as:

= 1/2(a + b)h

We then slot the given values into the formula. This will be:

1/2(15.8 + b) × 7.3 = 81.03.

7.3(15.8 + b)= 81.03 × 2

7.3(15.8 + b) = 162.06

115.34 + 7.3b = 162.06

7.3b = 162.06 - 115.34

7.3b = 46.72

b = 46.72/7.3

b = 6.4

Therefore, the answer is 6.4cm.

Zeros: (5 and 9)

Step-by-step explanation:

3a² -42a +135 = 3 (a² - 14a +45) = 3 (a-5) (a-9)

3 (a-5) (a-9) = 0

a = 5 or a = 9 ..... Zeros

Answer:

3/7 times 5/4

Step-by-step explanation:

when dividing fractions, all you do is keep the first fraction, change the sign to multiplication, and flip the last fraction. In this case it would be 3/7 and 5/4

Answer:

The answer is B: 3/7 times 5/4.

Step-by-step explanation:

The process is stay, change, flip.

Stay equals keep the first fraction the same (3/7).

Change equals change the operation (division to multiplication).

Flip equals flip the second fraction (flip 4/5 to 5/4).

Answer:

The simple interest that said investment yielded was 3.75% per year.

Step-by-step explanation:

Given that Sarah's current account balance is $ 2,600, and she made a single lump sum amount of $ 2,000 eight years ago into the account, to calculate the equivalent simple interest rate (quoted annually) that she earned the following calculation must be performed:

(2,600 - 2,000) / 8 = X

600/8 = X

75 = X

2,000 = 100

75 = X

75 x 100 / 2,000 = X

7,500 / 2,000 = X

3.75 = X

Thus, the simple interest that said investment yielded was 3.75% per year.

Answer:

0

Step-by-step explanation:

f(x) = y

To find f(2), it means to find the value of y when x = 2.

From the graph, when x = 2, the corresponding y-coordinate = 0.

Therefore,

f(2) = 0

Answer:

after 42 mm the next one is 63mm and after 198mm it is 946mm

Step-by-step explanation:

The Diameter of the second circle is 63 mm and the circumference of the third circle is 946.

The circumference of a circle is the distance along a line across it. In other words, the length of a straight line created by opening a circle matches the radius of the circle. The formula to calculate circumference is C = π * Diameter.

Given that circumference of the first circle is 198mm by that we can drive the value of the diameter(D₂). from the formula of the circumference

C =  π D₂

198 = 3.14 * D₂

D₂ = 63mm.

Given that the Diameter of the first circle is 198mm by that we can drive the value of the circumference. from the formula of the circumference

C₃ =  π D₃

C₃ = 3.14 * 301

C₃ = 946 mm.

Therefore, the missing dimensions of the circular object are D₂ is 63mm and C₃ is 946mm.

Answer:

Option c.

Step-by-step explanation:

Using the normal curve to approximate a sampling distribution:

For a sample size n and a proportion n, the normal curve can be used if:

[tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]

Option a:

[tex]np = 35*0.8 = 28 > 10[/tex]

[tex]n(1-p) = 35*0.2 = 7 < 10[/tex]

So option a cannot be used.

Option b:

[tex]np = 65*0.9 = 58.5 > 10[/tex]

[tex]n(1-p) = 65*0.1 = 6.5 < 10[/tex]

So option b cannot be used.

Option c:

[tex]np = 65*0.8 = 52 > 10[/tex]

[tex]n(1-p) = 65*0.2 = 13 > 10[/tex]

So option c can be used, and is the answer

Option d:

[tex]np = 35*0.9 = 31.5 > 10[/tex]

[tex]n(1-p) = 35*0.1 = 3.5 < 10[/tex]

So option d cannot be used.

The answer is given by option c.

Answer:

23.9425 (Round if needed)

Step-by-step explanation:

This is 2 half circles so you can find the area of a circle and divide it by 2.

First circle has a diameter of 6 cm

6/2=3 cm

So, circle has radius of 3.

Area of circle= 3.14(pi) radius^2

3.14 x 3^2= 28.26

28.26/2=14.13 cm

Area of first half circle= 14.13

Repeat that process for the second circle.

3.14 x 2.5^2=19.625

19.625/2=9.8125

14.13+9.8215=23.9425

Area=23.9425

Given:

A figure of a right triangle.

To find:

The value of x and value of y.

Solution:

In a right angle triangle,

[tex]\sin \theta = \dfrac{Opposite}{Hypotenuse}[/tex]

[tex]\cos \theta = \dfrac{Base}{Hypotenuse}[/tex]

In the given triangle,

[tex]\sin (60^\circ)=\dfrac{x}{6}[/tex]

[tex]\dfrac{\sqrt{3}}{2}=\dfrac{x}{6}[/tex]

[tex]\dfrac{\sqrt{3}}{2}\times 6=x[/tex]

[tex]3\sqrt{3}=x[/tex]

And,

[tex]\cos (60^\circ)=\dfrac{y}{6}[/tex]

[tex]\dfrac{1}{2}=\dfrac{y}{6}[/tex]

[tex]\dfrac{1}{2}\times 6=y[/tex]

[tex]3=y[/tex]

Therefore, the value of x is [tex]3\sqrt{3}[/tex] and the value of y is 3.

Answer:

Since the length of the sides respects the Pythagorean theorem, these points form a right triangle.

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Right triangle:

Sum of the squares of the two smaller sides is equal to the square of the largest side(Pythagorean theorem).

Length of side PQ:

P (-2, -3), Q (4, 1)

[tex]a = \sqrt{(4 - (-2))^2+(1 - (-3))^2} = \sqrt{6^2 + 4^2} = \sqrt{52}[/tex]

Length of side PR:

P (-2, -3), R (2,4)

[tex]b = \sqrt{(2 - (-2))^2+(4 - (-3))^2} = \sqrt{4^2 + 7^2} = \sqrt{65}[/tex]

Length of side QR

Q (4, 1), R (2,4)

[tex]c = \sqrt{(2 - 4)^2+(4 - 1)^2} = \sqrt{2^2 + 3^2} = \sqrt{13}[/tex]

Pythagorean Theorem:

Smaller sides: a and c

Largest side: b

So

[tex]a^2 + c^2 = b^2[/tex]

[tex](\sqrt{52})^2 + (\sqrt{13})^2 = (\sqrt{65})^2[/tex]

[tex]52 + 13 = 65[/tex]

[tex]65 = 65[/tex]

Since the length of the sides respects the Pythagorean theorem, these points form a right triangle.

Answer:

Step-by-step explanation:

sinx=(opposite side)/(hypotenuse)

There really is no ‘explanation’ as that ratio IS the definition of sin.
