Answer:

Stephen gets £147

Step-by-step explanation:

Given

Let

[tex]S = Stephen; B = Bridget; R = Richard[/tex]

So:

[tex]S + B + R = 490[/tex]

[tex]R = 2S[/tex]

[tex]S = 3B[/tex]

Required

Find S

Make B the subject in [tex]S = 3B[/tex]

[tex]B = \frac{S}{3}[/tex]

Substitute: [tex]R = 2S[/tex] and [tex]B = \frac{S}{3}[/tex] in [tex]S + B + R = 490[/tex]

[tex]S + \frac{S}{3} + 2S = 490[/tex]

Take LCM

[tex]\frac{3S + S + 6S}{3}= 490[/tex]

[tex]\frac{10S}{3}= 490[/tex]

Solve for S

[tex]S = \frac{490 * 3}{10}[/tex]

[tex]S = 49 * 3[/tex]

[tex]S = 147[/tex]

Answer:

The bigger pizza has a diameter of 14 inches, or a radius of 14 / 2 = 7 inches.

The smaller pizza has a diameter of 12 inches, or a radius of 12 / 2 = 6 inches.

Step-by-step explanation:

The area of a circle is πR2 where R is the radius.

The difference in the size of the pizzas is  

Area of bigger pizza - Area of smaller pizza

= π(7 inches)2 - π(6 inches)2 = = 49π inches2 - 36π inches2 = 13π inches2  

The area of the large pizza is 13π inches² larger than the area of the medium pizza.

The bigger pizza has a diameter of 14 inches,

a radius = 14 / 2 = 7 inches.

The smaller pizza has a diameter of 12 inches.

radius = 12 / 2 = 6 inches.

The area of the circle is defined as the product of the pie and the square of the radius.

The area of the circle =πR²

The area of a circle is πR², where R is the radius.

The difference in the size of the pizzas = Area of bigger pizza - Area of smaller pizza

= π(7 inches)² - π(6 inches)²

= 49π inches² - 36π inches²

= 13π inches²

Step-by-step explanation:

Answer:

5^6

Step-by-step explanation:

by the law of exponents,

5^2 * 5^(-8)

5^ [2+ (-8)]

5^(2-8) = 5^-6 = 1/5^6 = 5^6

Answer:

AN = 9

Step-by-step explanation:

so we can imagine this in a line like:

A---------------N---------------X

Step 1 : solve for x

AX=21 (our total)

because we know that AN+NX together makes AX, we put that into an equation

AN + NX = AX

(2x+1) + (3x) = 21

2x + 1 + 3x = 21  <-- subtract 1 from both sides

2x + 3x = 20  <-- add 2x +3x

5x = 20   <-- divide 5 from both sides

x = 4

Step 2 : input x into AN

AN = 2x + 1  <-- input 4 for x

AN = 2(4) + 1  <-- simplify from there

AN = 9

just did it

Answer:

The area of the rectangle is Length x width. So 12x4 would =48 sq cm. The area of the circle is ( 3.14 ) x r2.

The area of the circle would be = (3.14)x2^2)=12.56 cm sq.

So the total  area is= Area of rectangle +Area of circle

TA=48+12.56

TA=60.56 sq cm

because, in the sequence they are subtracting 3 in each one it goes so, first it was 16-3= 13, 13-3= 10, and so on. Hope I helped :3

Answer:

∠BCO = 55°

Step-by-step explanation:

The sum of all the angles in a triangle is always 180°, so we need to subtract 90° and 35° from 180° to get ∠BCO.

180° - 90° - 35° = 55°

x=12

Step-by-step explanation:

70+x+50+4x=180

combine like terms

120+5x=180

-120. -120

5x= 60

isolate x

5x=60

x=12

Step-by-step explanation:

Answer:

Complementary angles are 90 degrees, and supplementary angles are 180 degrees.

Step-by-step explanation

First you figure out the answer to the equation,then once u figure out the answer,you subtract it by 90 but, only subtract the complementary angles by 90. Afterwards,you do the same thing for finding the measure to B.

Step-by-step explanation:

there are 7 decimal places from between 2 and 3 to the very end. so the answer is 7

Answer: 2.36x^10

Step-by-step explanation:

Answer:

The arc length is 9.75 pi units

Step-by-step explanation:

Mathematically, we use the formula below to get the length of an arc

Length of an arc is;

theta/360 * 2 * pi * r

where theta is the central angle

for 3pi/4 ; let us convert to degrees

The degree measure is 180 degrees for pi

so 3pi/4 will be (3 * 180)/4 = 135 degrees

So we have the arc length as follows;

135/360 * 2 * pi * 13 = 9.75 pi unit
