A food production company is choosing between two suppliers of grain. Supplier A sells grain for $5.25 per bushel plus a delivery fee of $3 per bushel. Supplier B sells the grain for $6.50 per bushel plus a flat delivery fee of $1,500 each week. Which supplier would cost more if the production company bought 500 bushels of grain each week?

Answer:

Supplier A is cheaper than supplier B.

Step-by-step explanation:

Supplier A sells grain for $5.25 per bushel plus a delivery fee of $3 per bushel.

Supplier B sells the grain for $6.50 per bushel plus a flat delivery fee of $1,500 each week.

When 500 bushels are bought from supplier A.

(5.25\times500)+(3\times500)

=> 2625+1500=4125 dollars

When 500 bushels are bought from supplier B.

(6.50\times500)+1500

=> 3250+1500=4750 dollars

Therefore, Supplier A is cheaper than supplier B.

The Mendes family bought a new house 5 years ago for $100,000. The house is now worth $198,000. Assuming a steady rate of growth, what was the yearly rate of appreciation?

(new amount-old amount)=(198,000)-(100,000)=98% increase

98/5 years=19,600
Yr 1=$100,000+19,600=$119,600
Yr 2=$119,600+19,600=$139,200
Yr 3=$139,200+19,600=$158,800
Yr 4=$158,800+19,600=$178,400
Yr 5=$178,400+19,600=$198,000

The mortgage grew at a steady rate of $19,600 over the 5 years...

Terri is analyzing a circle, y2 + x2 = 36, and a linear function g(x). Will they intersect? y2 + x2 = 36 g(x) graph of the function y squared plus x squared equals 36 x g(x) −4 −4 −2 −2 2 2 Yes, at positive x-coordinates or zero Yes, at negative x-coordinates or zero Yes, at negative and positive x-coordinates or zero No, they will not intersect

Answer:

The graph of the circle and function g(x) intersects at the positive and negative x-coordinates as well as at the origin.

Step-by-step explanation:

The equation of circle is given as:

x^2+y^2=36

also the graph of the function g(x) is given by:

We are given a set of values in a table as:

  x         g(x)

−4       −4

 −2        −2

   2          2

Hence, the function g(x) could be computed with the help of slope intercept form of a equation as:

y=mx+c; where m denotes the slope of the line and c denotes the y intercept.

when x=-4 g(x)=y=-4

-4=-4m+c

also when x=-2 then y=g(x)=-2

-2=-2m+c

on solving the above two equations using elimination method we get,

m=1 and c=0

hence, y=g(x)=x

Now we are asked tgo find whether the graph of the circle and g(x) intersect each other or not.

Clearly from the graph we could see that the graph of the circle and function g(x) intersects at the positive and negative x-coordinates as well as at the origin.

A small plane is 4 miles by land away from the airport. The angle of elevation from the airport to the airplane is 6.5 degress. What is the altitude of the plane? Round your answer to the nearest tenth of a mile.

Make the drawing of the right triangle

x, the opposite side to the angle is the altitude of the plane

4 miles, is the adyacent side of the angle

the angle is 6.5°

then, tan(6.5°) = x / 4 miles

solve for x:

x = 4tang(6.5°) miles = 4(0.1139) = 1.25 miles

That would be C.

20x + 5y = 50
5y = - 20x + 50
y = -20/5x + 50/5
y = - 4x + 10
now in y = mx + b form. the m represents ur slope and the b represents ur y intercept. So here, u have a slope of -4 and a y intercept of 10.

If a is a rational number and b is a rational number, why could c be an irrational number? represents the solution set of the compound inequality mc011-1.jpg?

Because even though 'a' and 'b' are rational, and their squares are
also rational, that doesn't guarantee that the sum of their squares
has a rational square root.

Examples:

1 and 2
Sum of squares = 5
√5 is irrational

2 and 3
Sum of squares = 13
√13 is irrational

4 and 5
Sum of squares is 41
√41 is irrational

'c' is rational only when 'a', 'b', and 'c' form a . . . . . wait for it . . . . .

The value of x in this system of equations is 1. 3x y = 9 y = –4x 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x (–4x 10) = 9 –x 10 = 9 –x = –1 x = 1 what is the value of y?

We have two unknowns from the equation therefore, two equations are needed. These equations are:

3x + y = 9
y = –4x +10 

To solve for y, we first substitute the second equation to the first one.
3x + –4x +10= 9 
x = 1

We substitute the value of x to either of the equations and solve for y.

y = –4(1) +10 
y = 6

A customer went to a garden shop and bought some potting soil for $11.50 and 9 shrubs. the total bill was $94.75. write and solve an equation to find the price of each shrub. a. 9p 11.5p = $94.75; p = $4.62 b. 9p $11.50 = $94.75; p = $11.75 c. 9p $11.50 = $94.75; p = $9.25 d. 9(p $11.50) = $94.75; p = $5.00

Let

p---------> the price of each scrub

s----------> the price of the potting soil

T--------> total bill

we know that

 T=9p+s

in this problem

 T=\$94.75\\ s=\$11.50\\p=?

substitute the values in the formula above

 \$94.75=9p+\$11.50

solve for p

 9p=94.75-11.50

 9p=83.25

 p=9.25

therefore

the answer is the option C

 \$94.75=9p+\$11.50

 p=9.25

Solomon needs to justify the formula for the arc length of a sector. which expression best completes this argument? the circumference of a circle is given by the formula c=pi * d , where d is the diameter. because the diameter is twice the radius, c= 2 * pi * r. if equally sized central angles, each with a measure of n°, are drawn, the number of sectors that are formed will be equal to 360°/n° the arc length of each sector is the circumference divided by the number of sectors, or _____. therefore, the arc length of a sector of a circle with a central angle of n° is given by 2*pi*r*n/360 or pi*r*n/180 . a. 2*pi*r/270/n b. 2*pi*r/360/n c. 2*pi*r/180/n d. 2*pi*r/90/n

Answer:  The answer is (b). \dfrac{2\pi r}{\frac{360^\circ}{n^\circ}}.


Step-by-step explanation: Let us consider a circle with centre "O" and radius OA=OB=r units. We know that the circumference of a circle is 2\pi\times radius~of~the~circle, so the circumference of Circle 'C' is given by

Circumference=2\pi r.

Also, let us central angles of equal size of 'n°', the the number of sectors formed is given by

no.~of~sectors=\dfrac{360^\circ}{n^\circ}.

Now, the formula for arc length of a sector is given by

arc~length~of~of~a~sector=\dfrac{Circumference~of~the~circle}{no.~of~equally~sized~sectors}.

arc~length~of~of~a~sector=\dfrac{2\pi r}{\frac{360^\circ}{n^\circ}}.

Thus, (b) is the correct option.

Answer:

37  and  39

Let

x-------> the first odd number

x+2----> the second consecutive odd number

we know that

x+\frac{x+2}{3}=50 ----> linear equation that represent the situation

solve for x
