Answer: roughly 4.2593

Step-by-step explanation:

920/216

put the equation through a calculator

approx. 4.2593

Answer:

17.037037

Step-by-step explanation:

Answer:

:

1.

centre(h,k)=(-13,9)

radius (r)=6

we have

equation of the circle is

(x-h)²+(y-k)²=r²

(x+13)²+(y-9)²=6²

(x+13)²+(y-9)²=36you can write this equation too

x²+26x+169+y²-18y+81=36

x²+y²+26x-18y+169+81-36=0

x²+y²+26x-18y +214=0

is a required equation of the circle.

2.

centre(h,k)=(1,-1)

radius (r)=11

we have

equation of the circle is

(x-h)²+(y-k)²=r²

(x-1)²+(y+1)²=11²

(x-1)²+(y+1)²=121

you can write this equation too

x²-2x+1+y²+2y+1=121

x²+y²-2x+2y=121-2

x²+y²-2x+2y=119

is a required equation of the circle.

3.

centre (h,k)=(3,1)

radius (r)=4units.

we have

equation of the circle is

(x-h)²+(y-k)²=r²

(x-3)²+(y-1)²=4²

(x-3)²+(y-1)²=16 is a required equation.

4.

centre(h,k)=(4,-2)

radius (r)=3

we have

equation of the circle is

(x-h)²+(y-k)²=r²

(x-4)²+(y+2)²=3²

(x-4)²+(y+2)²=9

you can write this equation

Answer:

24

Step-by-step explanation:

4/17

4= favourable

17=possible

102/17=6

so the factor is 6

which means 4x6 (24) is the answer

Answer:

192 minutes

Step-by-step explanation:

if 100% is 8 hours

50% is 4 hours

75% is 2 hour

then 60% = 60/12.5 = 4.8 hours left

8-4.8 = 3.2 hours there

3.2x 60 = 192 minutes

Answer:

1824in. 2

Step-by-step explanation:

first, we need to cut it to two figure (a triangle and a rectangle), then calculate each of the area.

the area of triangle

= 12in.×48in.×1/2

= 576in.2×1/2

= 288in.2

the area of rectangle

= 32in.×48in.

= 1536in.2

the area

= 288in.2+1536in.2

= 1824in.2

Answer:

im leaning on parallelogram

Step-by-step explanation:

Parallelogram, Quadrilateral, and Rectangles

First off both of these images are parallelogram because the arrows show that both the rectangle and the square (diamond/whatever you want to call it) have pairs of parallel sides so we know that both these shapes are parallelograms

Secondly, these shapes are both quadrilaterals. A quadrilateral, by definition, is simply a four-sided figure. Both a rectangle and a square are four-sided figures so these are both quadrilaterals.

Lastly, these figures are both rectangles. Yes I know one is a square and one is a rectangle but a square is a special four sided figure that can classify as a rectangle. Every square is a rectangle but not every rectangle is a square. A rectangle by definition is a four sided polygon with two pairs of parallel sides, congruent sides, and four 90 degree interior angles.

Answer:

Probability of getting Peach scone pastry = 3 / 5

Step-by-step explanation:

Given:

Total number of pastries in store = 15

Number of Peach scone pastry = 6

Find:

Probability of getting Peach scone pastry

Computation:

Probability = Number of event / Total outcomes

Probability of getting Peach scone pastry = Number of Peach scone pastry / Total number of pastries in store

Probability of getting Peach scone pastry = 6 / 15

Probability of getting Peach scone pastry = 3 / 5

Given:

The actual length of side y is 22cm.

To find:

The length of side x by using the scale drawing.

Solution:

We know that the corresponding sides of original figure and scale drawing are proportional.

[tex]\dfrac{x}{1.8}=\dfrac{y}{1.4}[/tex]

[tex]\dfrac{x}{1.8}=\dfrac{22}{1.4}[/tex]

[tex]x=\dfrac{22}{1.4}\times 1.8[/tex]

[tex]x\approx 28.286[/tex]

Therefore, the length of side x is about 28.286 cm.

Answer:if it's proportional, it should not pass through the origin

Step-by-step explanation:

Based on the provided answers already in the table, 8 strawberries seem to be picked consistently between a span of three hours. The graph would then just be a straight line going directly up to the right.

x y

0 0

1 8

2 16

3 24

4 32

Yes, the line passes through the origin. (0,0.)

Step-by-step explanation:

-30+9x=-0.5 |x-1| -2

from the graph, we can see that both curves intersect at (3,-3)⇒x=3

put x=3 in LHS&RHS

⇒LHS=-30+9(3)=-3

RHS=-0.5 |3-1|-2=

-1/2×2-2=-1-2=-3

so the answer will be 3..

Answer:

[tex]circumference = 2\pi \: r \\ = 2 \times \frac{22}{7} \times 14 \\ 88 \: m \: fence[/tex]

Step-by-step explanation:

Part A:

(8x+6)/4= 2x+ 1.5

Part B:

72= (8x+6)

8x= 72-6

8x= 66

x= 8.25

the side length = 2x+1.5= 2(8.25)+1.5= 18 centimetres
