The conclusion is:

Answer:

If a=0.6 and b=0.75, then a·b=9/20 and a/b=4/5

Step-by-step explanation:

The value of a•b =0.045 and a/b = 8

A number expressed as a quotient, in which a numerator is divided by a denominator

given: a=0.6, b= 0.075

Now, a*b= 0.6*0.075

               = 0.045

and, a/b

= 0.6/0.075

=8

Hence, a*b= 0.045 and a/b =8

Given:

The arithmetic sequence is:

10, 12, 14, 16, ...

To find:

The function that generates the given sequence if n is an integer.

Solution:

We have,

10, 12, 14, 16, ...

Here, the first term is 10 and the common difference is:

[tex]d=a_2-a_1[/tex]

[tex]d=12-10[/tex]

[tex]d=2[/tex]

The nth term of an arithmetic sequence is:

[tex]a_n=a+(n-1)d[/tex]

Where, a is the first term, d is the common difference and [tex]n\geq 1[/tex].

Putting [tex]a=10,d=2[/tex] in the above formula, we get

[tex]a_n=10+(n-1)2[/tex]

[tex]a_n=10+2n-2[/tex]

[tex]a_n=8+2n[/tex]

Therefore, the function [tex]a_n=8+2n, n\geq 1[/tex] generates the sequence.

Answer:

No

Step-by-step explanation:

you can check with the pythagorean theory

[tex]8^{2}+9^{2} =12^{2}[/tex]

64 + 81 = 144

145 = 144

this is not true, therefore those side lengths do not make a right triangle.

Answer:

4

Step-by-step explanation:

This equation is in the form y = mx + b

In all cases, m equals the slope

So in this case, the slope would be 4.

Answer:

However, if you're trying to find the arc length of a partial circle, it's not the same as the circumference of the same circle wholly. You need to find out the circumference of the whole circle first before you can find the arc length (or the circumference of the partial circle).

Answer:10

Step-by-step explanation:24-6-8=10

The distance travelled by the ray will be 26 inches. Then the correct option is B.

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

In a science experiment, a student concluded that a ray has to travel a distance from one corner at the top of the rectangular prism to the opposite side where the surface touching the floor is intersected.

If the length, width, and height of the prism are given as 24 inches and 8 inches, 6 inches respectively.

Then the distance travelled by the ray will be

We know the formula

D² = L² + W² + H²

We have

L = 24 in

W = 6 in

H = 8 in

Then the distance will be

D² = 24² + 6² + 8²

D² = 576 + 36 + 64

D² = 676

D = 26 in

Thus, the correct option is B.

Answer:

Step-by-step explanation:

Answer:

The value of x is 28°

Step-by-step explanation:

2x + 1 and 33° together forms 90° angle.

So, we need to find the angle at the 2x + 1.

--> 90° - 33°

= 57°

So, 2x + 1 gives 57°.

So, to find x :-

2x + 1 = 57°

2x = 57 - 1

2x = 56

x = [tex]\frac{56}{2}[/tex]

x = 28

Answer: $826.8

Step-by-step explanation:

First, we add the amount of money that the machines sold for:

$420 + $360 = $780

Next, we multiply it by the sales tax, 6%,

$780 x 6%(0.06) = $46.80

Finally, we add this to the total:

$780 + $46.80 = $826.80

Alternatively, you can add the total sales and multiply by 106% using the 2-step method.

Answer:

x>3

Step-by-step explanation:

you would subtract 5x from 2x and get -3x+10 < 1

then subtract 10 from 1 and get -9 so

-3x<-9 then divide and flip sign x>3 hope this helps

Answer:

x>3

Step-by-step explanation:

1.subtract both sides

2x+10 -5 < 5x+1 -5

-3x+10<1

2.subtract 10 from both sides

-3x+10 -10 < 1 -10

-3x<-9

3.divide both sides with number including x

-3x < -9

-3      -3

= x > 3

Answer:

I would choose two 12 inch pizza if I want more pizza as two 12 inch pizzas have larger circumference than one 18 inch pizza

c=πd

circumference= pie × diameter

c=2πr

circumference= 2×pie×radius

A=πr²

Area= pie×square radius

Pie= 22/7, 3.14( depends on the question, sometimes the value of pie will be given in the question)

radius= half of diameter

To find perimeter of circle use 2πr

To find area of circle use πr² or πd

Answer:

148 = x

Step-by-step explanation:

Using the Secant and Tangent Intersection theorem we can say;

38 = 1/2 (x - 72)

38 = 1/2x - 36

74 = 1/2x

(74)/(1/2) = x

148 = x
