Answer:
267x2 -8x -8 where
x=- 4± 2√ 538/267
Step-by-step explanation:
x2 - 2x -89x2 - 16x2 - 163x2 + 10 x + 8
= x2 -89x2 - 16x2 - 163x2 - 2x+ 10 x + 8
= -267x2+8x +8
= 267x2 -8x -8
First the like terms are arranged and then added . All the co efficients of x2 are added and x are added separately.
Using the quadratic equation to find the value of x
a= 267 , b= -8 and c= -8
x= -b±√b²- 4ac/ 2a
x= -8±√64 +8544/534
x= -8±√8608/534
x=-8±√ 2 x 2 x 2 x 2 x 2 x 269/534
x=-8± 4√ 2 x 269/534
x=- 4± 2√ 2 x 269/267
x=- 4± 2√ 538/267

Water flows through a pipe at a rate of 91 fluid ounces every 2.5 weeks. Express this rate of flow in cups per hour. Round your answer to the nearest hundredth.
Answer:
The answer is "[tex]0.22\ \frac{\ fl \ oz}{\ hours}\\\\[/tex]"
Step-by-step explanation:
rate[tex]=\frac{91 \ fl oz}{2.5 \ weeks}\\\\[/tex]
Requird
Calculating the rate as per hour:
[tex]rate=\frac{91 \ fl oz}{2.5 \ weeks}\\\\[/tex]
there are 168 hoours in week so the ate becomes
[tex]rate=\frac{91 \ fl oz}{2.5 \times 168 \ hours}\\\\[/tex]
[tex]=\frac{91 \ fl oz}{420 \ hours}\\\\= 0.2167 \ \frac{\ fl \ oz}{\ hours}\\\\[/tex]
[tex]=0.22 \ \ \frac{\ fl \ oz}{\ hours}\\\\[/tex]

A large pizza has a diameter of 14 inches. A medium pizza has a diameter of 10 inches. How much larger is the area of the large pizza than the area of the medium pizza. Round your answer to the nearest hundredth place. ** Use 3.14
A. 12.56
B. 50.24
C. 75.36
D. 78.50
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.
What is the area of the circle?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

if the central angle is 3pie/4 and the radius is 13 what's the arc length
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

N is between A and X. AN = 2x + 1, NX = 3x, and AX = 21. what is AN?
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

£490 is divided between Richard, Stephen & Bridget so that Richard gets twice as much as Stephen, and Stephen gets three times as much as Bridget. How much does Stephen get?
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]
Stephen gets £147
If angle obc=90, angle boc =35 what is the measure of angle bco??? Help this is due today!!
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°
