1400/85 = 16.47

largest integer below that is 16

Answer:

A) 0 (no solutions)

Step-by-step explanation:

Solve the equation:

3x - 10(x+2) = 13 - 7x

3x - 10x -20 = 13 - 7x

-7x - 20 = 13 - 7x

-20 = 13

Since both sides are clearly not equal to each other, no solution can satisfy both sides to be equal to each other. So A is correct.

Answer:

It would be 0

Step-by-step explanation:

because its -7x+20=13-7x which in the end would 20=13

Answer:

20x-3y

Step-by-step explanation:

combine the like terms

so first do 10x-2x=8x

then you're gonna add from the line the 10x and the 2x which is going to give you 20x

no finally you are left with one number with the y variable, that is 3y.

Therefore your answer is 20x-3y

To maximize the chances of buying cherries as well as asparagus, Elena should choose the North market. There is 0.44 probability of both cherries and asparagus.

"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."

P(A) = n(A)/n(S)

where,  n(A) is the number of favorable outcomes,

n(S) is the total number of events in the sample space.

"These are two events wherein the occurrence of one event does not affect the occurrence of another event"

If A, B are independent events then their combine probability is given by,

P(A ∩ B) = P(A) × P(B)

For given example,

Let P(A) represents the probability of cherries available at market and P(B) represents the probability of asparagus available at market.

The availability of cherries and the availability of asparagus are

independent of each other

So, the probability of buying cherries as well as asparagus from the North market would be,

⇒ P = P(A) × P(B)

⇒ P = 0.8 × 0.55

⇒ P = 0.44                                     ....................(1)

And the probability of buying cherries as well as asparagus from the South market would be,

⇒ P = P(A) × P(B)

⇒ P = 0.65 × 0.6

⇒ P = 0.39                                    .......................(2)

From (1) and (2),

To maximize the chances of buying cherries as well as asparagus, Elena should choose the North market. There is 0.44 probability of both cherries and asparagus.

Answer:

OC=48

RK=100

Step-by-step explanation:

We can use proportions to find both OC and RK.

[tex]\frac{OK}{KY} =\frac{OC}{RY}[/tex]

[tex]\frac{12}{24} =\frac{OC}{96}[/tex]

[tex]24OC=1152[/tex]

[tex]OC=48[/tex]

[tex]\frac{KC}{RK} =\frac{OK}{KY}[/tex]

[tex]\frac{50}{RK} =\frac{12}{24}[/tex]

[tex]12RK=1200[/tex]

[tex]RK=100[/tex]

Answer:

RK = 100

OC = 48

Step-by-step explanation:

Scale factor = 12/24 = 1/2

1/2 RK = 50

RK = 2* 50

RK = 100

1/2 RY = OC

1/2 * 96 = OC

48 = OC

OC = 48

Answer:

Step-by-step explanation:

Use a^2 + b^2 = c^2 to get the third side.

a = 12

b = ?

c = 37

a^2 + b^2 = c^2

144 + b^2 = 37^2

144 + b^2 = 1369       Subtract 144 from both sides.

-144              -144

b^2 = 1225                Take the square root of both sides

sqrt(b^2) = sqrt(1225)

b = 35

Perimeter = a + b + c

Perimeter = 12 + 35 + 37

Perimeter = 84

Answer: The correct answer is C

-1/4r+6p

Step-by-step explanation:

Answer:

(1, 3)

Step-by-step explanation:

Given the expression

x+y = 4 ... 1

y = 2x+1 ....2

Substitute equation 2 into 1

x + (2x+1) = 4

3x + 1 = 4

3x = 4-1

x = 3/3

x = 1

Since y = 2x + 1

y = 2(1) + 1

y = 3

Hence the solution to the equation is (1,3). This means that the coordinate point on the graph where both lines intersect will be at (1, 3)

Answer:

C  (n - 15 = 4)

Step-by-step explanation:

This is the answer becuase it can be rewritten as:

n - 4 = 15 (by subtracting 4 from both sides and adding 15 to both sides);

this equation describes the "written" (verbal) equation.

Answer:

$800 total paid for four loins. Everyone gets one ribeye so price of steak per person is four dollars.

Step-by-step explanation:

1 ribeye per person -> 50 ribeyes per loin -> 200 (people going)/50 (people fed per loin) = 4 (loins needed) -> $200.00 x 4 loins = $800 of loin total and 4 dollars per ribeye (1 ribeye per person)

answer:

1/433 (decimal: 0.002309)

step-by-step explanation:

5/2,165

= 1/433

to change 1/433 to decimal we'll divide the numerator by the denominator-

1÷433

=0.00230946882

so we're going to round to the ten-millionths place

5 or more raise the floor, 5 or less let it rest

4>5

so 0.002309

good luck :)

i hope this helps

Answer:

19%

Step-by-step explanation:

40/50 = x/100

solve for x

x is equal to 20%

but out of the answer choices it's 19%.

Answer: 19%

Step-by-step explanation:

50, percentage decreased by 60% (percent) of its value = 20

50, percentage decreased by 80% (percent) of its value = 10

50, percentage decreased by 19% (percent) of its value = 40.5

50, percentage decreased by 40% (percent) of its value = 30

Hence, the answer is 19%

Answer:

c is the answer becoz Evey angle make 180 degree and as 6 is used

Answer:cos( A + B ) = cosAcosB - sinAsinB ;

cos( A + B ) / ( cosAsinB ) = ( cosAcosB - sinAsinB ) / ( cosAsinB ) = ( cosAcosB ) / ( cosAsinB ) - ( sinAsinB ) / ( cosAsinB ) = cosB / sinB - sinA / cosA = cotB - tanA ;

tan²(x) - sin²(x) = sin²(x)/cos²(x) - sin²(x)

… = sin²(x) (1/cos²(x) - 1)

… = sin²(x) (sec²(x) - 1)

… = sin²(x) tan²(x)

Step-by-step explanation:

The function that models the height of the curved arch in feet, f(x) = -0.0009·x² + 1.24·x + 1.65

The height of the platform = 2 feet + The maximum height of the arch

The amount of stretch of the bungee before retracting = 420 feet

The vertex of the parabola is the point x = (-b/2·a), from which we get;

At the maximum height of the arch, x = -1.24/(2 × -0.0009) = 6,200/9 =  688.[tex]\overline 8[/tex]

The maximum height of the arch = f(688.[tex]\overline 8[/tex]), therefore, we have;

f(688.[tex]\overline 8[/tex]) = -0.0009×(688.[tex]\overline 8[/tex])² + 1.24 × (688.[tex]\overline 8[/tex]) + 1.65 = 428.76[tex]\overline 1[/tex]

The maximum height of the arch = 428.76[tex]\overline 1[/tex] feet

The height of the platform above the ground = 2 ft. + 428.76[tex]\overline 1[/tex] ft. = 430.76[tex]\overline 1[/tex] ft.

Therefore;

The height of the platform above the ground = 430.76[tex]\overline 1[/tex] feet > The amount the bungee will stretch before retracting = 420 ft.

430.76[tex]\overline 1[/tex] ft, > 420 ft.

Therefore, the jumper is totally safe.
