Step-by-step explanation:

1/6*1/6

Answer:5:6

Step-by-step explanation:

a = ( 1 , 6 )

b = ( 4 , 9 )

[tex]slope = \frac{y(b) - y(a)}{x(b) - x(a)} \\ [/tex]

Now just need to put the coordinates in the above equation :

[tex]slope = \frac{9 - 6}{4 - 1} \\ [/tex]

[tex]slope = \frac{3}{3} \\ [/tex]

[tex]slope = 1[/tex]

Answer:

x= 2b-a

Step-by-step explanation:

Answer:

x=2b-a

Step-by-step explanation:

The first step is to subtract 2a from both sides to get the equation 2x=4b-2a

The next step is to divide by 2 so you can get x by itself which turns the equation to x=2b-a

Step-by-step explanation:

Answer:

I am expected to win $150

Step-by-step explanation:

We need to calculate the probability of drawing 2 black cards with replacement

There are 26 black cards in a deck of cards

The probability of drawing a black card is thus 26/52 = 1/2

So the probability of drawing two black cards in succession with replacement will be 1/2 * 1/2 = 1/4

So the probability of not drawing the two in succession will be 1 - 1/4 = 3/4

so out of twenty trials the number of times the drawing will occur will be 1/4 * 20 = 5 times

The number of times it will not occur will be 20-5 = 15 times

The amount my friend will win will be 5 * 30 = 150

The amount I will win will be 20 * 15 = 300

The amount I expect to win in the deal will be 300-150 = $150

Step-by-step explanation:

diameter of semicircle is 6 so radius is 6/2=3

so perimeter of the circle would be

p=2πr

p=2π*3=6π=18.8

But we have a semicircle so perimeter will be

P=p/2=18.8/2=9.4

The perimeter of the figure now would be

Perimeter=9+8+8+9.4=25+9.4=34 approximately.

The perimeter of the figure below, composed of an isosceles trapezoid and one semicircle is 34.4 units.

The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.

From the given figure, equal sides of an isosceles trapezoid is 8 units, and parallel sides are 9 units and 6 units.

Radius of semicircle is 6/2 = 3 units

Now, perimeter = 9+8+8+Circumfrence of a semicircle

= 25+πr

= 25+3.14×3

= 25+9.42

= 34.4

Therefore, the perimeter is 34.4 units.

Answer:

17[tex]\frac{1}{3}[/tex]miles

40miles

Step-by-step explanation:

Given parameters;

Distance traveled by  the car = 1[tex]\frac{1}{2}[/tex]miles  = [tex]\frac{3}{2}[/tex]miles

Time taken = 2[tex]\frac{1}{4}[/tex]minutes  = [tex]\frac{9}{4}[/tex]minutes

Unknown:

Distance covered in 26minutes and in 1hr = ?

Solution:

Speed is the rate of change of distance with time.

   Speed  = [tex]\frac{distance}{time taken}[/tex]

A. Insert the parameters and find the speed;

   Speed  = [tex]\frac{\frac{3}{2} }{\frac{9}{4} }[/tex] = [tex]\frac{3}{2}[/tex] x [tex]\frac{4}{9}[/tex] = [tex]\frac{2}{3}[/tex]miles/minutes

Distance covered in 26minutes;

   Distance  = speed x time

   Distance  = [tex]\frac{2}{3}[/tex] x 26  = [tex]\frac{52}{3}[/tex] miles  = 17[tex]\frac{1}{3}[/tex]miles

B. Distance covered in 1hr or 60minutes;

He is wrong

Step-by-step explanation:

105≠ 50

10+10+10+10=50

5(10)= 50

To get 105 you would have to add 10 ten times and then add 5. Adding ten five times will only give you are value of 50.

Answer:

800

Step-by-step explanation:

9 goes into 72 eight times, nine goes into 0 zero times

The complete statement is as follows:

The quotient of, 7200/9 = 800.

Quotient is the result which we get by dividing the one number by the other.

Where, the number which is getting divided is known as 'dividend'  and the number which divides the dividend is known as 'divisor'.

So,

Quotient = Dividend ÷ Divisor.

Or,

[tex]\text{Quotient} = \frac{\text{Dividend}}{\text{Divisor}}[/tex]

In 7200÷9, 7200 is dividend and 9 is divisor. We have to find the quotient.

Applying the division on 7200 by 9.

Since, 9 is very less than 72. Take the first 2 digits.

72÷9 = 8

There is no remainder.

Now, take three digits:

720÷9 = 80

Still no remainder is here.

Move to the last digit (0) and apply division.

7200÷9 = 800

No remainder is there.

That means the quotient of, 7200 divided by 9 is 800.

Hence, the quotient of 7200/9 = 800.

Answer:

2x+y=−7

Step-by-step explanation:

Sum of two angles that are complementary = 90°

Let the smaller angle be x .

Then the larger angle = 2x

Let us make an equation to find the measure of both the angles :-

[tex]2x + x = 90[/tex]

[tex]3x = 90[/tex]

[tex]x = \frac{90}{3} [/tex]

[tex]x = 30[/tex]

Which means :-

Measure of the small angle = 30°

Measure of the larger angle = 2 × 30 = 60°

Therefore , the measure of the bigger angle is 60° .
