Answer:

44

Step-by-step explanation:

x + (x+2) + (x+4) + (x+6) + (x+8) + (x+10) = 294
Combine all like terms for x and integers
6x + 30 = 294

Minus 30 on both sides
6x = 264
Divide by 6
x = 44

Answer:

Step-by-step explanation:

Let's name the 6 consecutive terms as

We know that:

Solution:

Hence, the smallest number among the six consecutive numbers is 44.

In the queston given, we have a quadratic equation which we are asked to solve only with quadratic formula. The solution of the equation are 1 and 3/2

Data;

Quadratic formula is used to solve quadratic equations and it is given as

[tex]x = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}[/tex]

Let's substitute the values and solve the quadratic equation.

[tex]x = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}\\x = \frac{-5 +- \sqrt{5^2 - 4*(-2)*(-3)} }{2*(-2)} \\x = \frac{-5+-\sqrt{25-24} }{-4} \\x = \frac{-5+- \sqrt{1} }{-4} \\x = \frac{-5+1}{-4} \\x= \frac{-4}{-4} = 1\\or\\x = \frac{-5-1}{-4} \\x = \frac{3}{2}[/tex]

From the calculations above, the solutions to this equation are 1 or 3/2

Answer:

78.54 ft^2

Step-by-step explanation:

The area of a circle is pi*r^2

R is the radius, which is half the diameter, so 5.

5^2 is 25, and that times pi is about 78. 54. Because this is feet and area is squared, our unit is ft^2

Answer: 0.727 hours

Step-by-step explanation:

Call A’s distance from A’s house “a(t)” when t hours have passed. Then a(t) = 60t, because distance = rate x time.

Call B’s distance from A’s house “b(t)”. Then b(t) = 162 - 72t, because they start 162 miles away and subtract miles as time elapses.

The time at which they meet will be when a(t) = b(t). (Think about it). So now we just solve for t:

60t = 162 - 72t

132t = 162

t = 1.227 hours.

HOWEVER this isn’t quite what they asked for. They want the time they meet since B left (not A), and since B left .5 hours after, we must subtract .5. Thus the answer is 0.727 hours.

The value of length and width of the rectangle is L = 28.8 yd , W = 7.2 yd

In the above question, it is given that

Let the length be L and width be W of the given Rectangle

The length of a rectangle is 4yd longer than its width

We can write it in mathematical equation as,

L = 4W  ......eqn 1

Also, it is given that, the perimeter of the rectangle is = 72yd

And, we know that, the perimeter of rectangle = 2(L+ W)

72 = 2(L + W)

Putting value of eqn 1 in the above equation, we will get,

72 = 2( 4W + W)

36 = 5W

W = 7.2 yd

Putting the value of W = 7.2yd in eqn 1 we get,

L = 4( 7.2)

L = 28.8 yd

Hence, the value of length and width of the rectangle is L = 28.8 yd , W = 7.2 yd

Answer:

Step-by-step explanation:

Let w represent the width of the field in yards. Then 4w-9 is the length. The perimeter is given by the formula ...

  P = 2(L+W)

Substituting given values, we have ...

  492 = 2((4w-9) +w)

  246 = 5w -9 . . . . . . . divide by 2

  255 = 5w . . . . . . . . add 9

  51 = w . . . . . . . . . divide by 5

  4w -9 = 4(51) -9 = 195 . . . . the length of the field

The width is 51 yards.

The length is 195 yards.

Answer:

replace the value of x but x cannot be 0 or a negative number

Step-by-step explanation:

for example:

replace x with 1===> y will be =0 cuz ln(1) = 0

replace x with 2==> y will be = 0.7 cuz ln(2)= 0.7

replace x with 3==> y will be = 1.1 cuz ln(3)= 1.1

replace x with 4==> y will be =  1.4 cuz ln(4)= 1.4

Step-by-step explanation:

5

Answer:

5

Step-by-step explanation:

convert the mixed numbers to fractions:

2 1/2 = 5/2

divide the fractions that are equivalent to multiplication by the reciprocal of the second fraction:

5/2 ÷ 1/2 would = 5/2 x 2/1

once rearranged, multiply all of the numerators by each other. do the same with the denominators and form a new fraction with these values:

5x2 = 10

2x1 = 2

--

10/2

the GCF of 10 and 2 is 2. the result can be simplified by dividing both the numerator and denominator by 2
