Answer:

1,000 days

Step-by-step explanation:

6 tires per minute = 600 per hour

600 per hour times 10 hours = 6,000 per day

Divide 6,000,000 by 6,000 per day = 1000 days.

Answer:

When you multiply two imaginary numbers, you are essentially multiplying them by itself or squaring them. If we recall, an imaginary number is the square root of -1. By squaring this number, you're eliminating the square root, ending up with -1 (aka a real number).

Step-by-step explanation:

smart boi

Step-by-step explanation:

A = (3, 6)

B = (6, 9)

C = (9, 3)

first scaled down (dilated) by the factor of 1/3 in the direction of the origin = point (0, 0).

then moved left by 2 units and down by 3 units.

the dilation about the origin simply multiplies each coordinate by the scale factor.

Ad = (3×1/3, 6×1/3) = (1, 2)

Bd = (6×1/3, 9×1/3) = (2, 3)

Cd = (9×1/3, 3×1/3) = (3, 1)

to move 2 units to the left means to subtract 2 from the x coordinates.

to move 3 units down means to subtract 3 from the y coordinates.

A' = (1-2, 2-3) = (-1, -1)

B' = (2-2, 3-3) = (0, 0)

C' = (3-2, 1-3) = (1, -2)

therefore, B is the right answer option.

Answer:

One of the earliest known mathematicians were Thales of Miletus.

Archimedes of Syracuse

The first calculation of π ( pi ) was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.

Answer:

4:1

Step-by-step explanation:

So, although the ratio 8:2 is technically correct, it is not in its simplest form. To get it into its simplest form you need to find the largest multiplying factor that is the same for both numbers. In this case, 2 is the largest factor because it goes into both 2 and 8. Now, you need to divide the entire ratio by 2 the reach the simplest form, so 8 divided by 2 equals 4, and 2 divided by 2 equals 1. This gives us our final ratio of 4:1.

Step-by-step explanation:

Answer:

21.15 ft

Step-by-step explanation:

18.7 - 14.3 = 4.4 = pool depth

25.55-4.4 = 21.15 = slide height

Answer:

The height of the tallest water slide is 58.55 feet.

Step-by-step explanation:

To find the height of the tallest waterslide, we need to add the height from the surface of the pool to the point where Dominic reached before going down the water slide and the height of the water slide itself.

Dominic jumped from a height of 14.3 feet above the surface of the pool and traveled 18.7 feet straight down into the water, so his total distance from the surface of the pool to the point where he started going up the water slide is:

14.3 feet + 18.7 feet = 33 feet

From there, he traveled up 25.55 feet to the top of the water slide, so the height of the tallest water slide is:

33 feet + 25.55 feet = 58.55 feet

Therefore, the height of the tallest water slide is 58.55 feet.

Answer:

3102.12

Step-by-step explanation:

add the starting weight 788.52 plus the weight he gained 2.313.6

788.52 + 2.313.6 = 3102.12

Answer:

Therefore, the values of "x" and "y" are -1000/312 and -115/39 respectively.

Step-by-step explanation:

[tex] \sf \leadsto 8x - 7y = -5 - - - (i)[/tex]

[tex] \sf \leadsto -x + 4y = -15 - - - (ii)[/tex]

By first equation,

[tex] \sf \leadsto 8x - 7y = -5[/tex]

[tex] \sf \leadsto 8x = -5 + 7y[/tex]

[tex] \sf \leadsto x = \dfrac{-5 + 7y}{8} [/tex]

Now, we can find the original value of y.

[tex] \sf \leadsto -x + 4y = -15[/tex]

[tex] \sf \leadsto \bigg( \dfrac{-5 + 7y}{8} \bigg) + 4y = -15[/tex]

[tex] \sf \leadsto \dfrac{-5 + 7y}{8} + 4y = -15[/tex]

[tex] \sf \leadsto \dfrac{-5 + 7y + 32y}{8} = -15[/tex]

[tex] \sf \leadsto \dfrac{-5 + 39y}{8} = -15[/tex]

[tex] \sf \leadsto -5 + 39y = -15(8)[/tex]

[tex] \sf \leadsto -5 + 39y = -120[/tex]

[tex] \sf \leadsto 39y = -120 + 5[/tex]

[tex] \sf \leadsto 39y = - 115[/tex]

[tex] \sf \leadsto y = \dfrac{ - 115}{39} [/tex]

Now, we can find the original value of x.

[tex] \sf \leadsto 8x - 7y = -5[/tex]

[tex] \sf \leadsto 8x -7 \bigg( \dfrac{ - 115}{39} \bigg) = -5[/tex]

[tex] \sf \leadsto 8x + \dfrac{805}{39} = -5[/tex]

[tex] \sf \leadsto \dfrac{312x + 805}{39} = -5[/tex]

[tex] \sf \leadsto 312x + 805 = -5(39)[/tex]

[tex] \sf \leadsto 312x + 805 = -195[/tex]

[tex] \sf \leadsto 312x = -195 - 805[/tex]

[tex] \sf \leadsto 312x = -1000[/tex]

[tex] \sf \leadsto x = \dfrac{-1000}{312} [/tex]

Answer:

x^2+y^2=256

Step-by-step explanation:

The general formula for a circle is (x - h)^2 + (y - k)^2 = r^2; where (h , k).

Thus, (x - 0)^2 + (y - 0)^2 = (16)^2 is x^2 + y^2 = 256

Answer:

2b[tex]^{8}[/tex]

Answer:

Step-by-step explanation:

y = x(x^2 -5x + 6)      Factor out a common term (GCF)

y = x(x - 2) (x - 3)       Factor the trinomial

     (x - 2) = 0     (x - 3) = 0      x = 0

 Therefore x = 2, 3, or 0

Answer:

424,752.7 cm³

Step-by-step explanation:

Since you need to convert from English units to Metric units, you can do that first.

Convert each measurement to centimeters instead of feet since your final answer is in cubic centimeters.

1 foot = 30.48 centimeters

Length = 3 ft    30.48cm

              -----  x ------------    =  91.44 cm

                1            1 ft

Width =  2 ft       30.48cm

            -------  x  -------------  =   60.96 cm

                1             1 ft

Height = 2.5 ft      30.48cm

              --------  x  ------------  =  76.2 cm

                  1            1 ft

The volume is equal to L x W x H

91.44cm x 60.96cm x 76.2cm = 424,752.7 cubic centimeters

Answer:

(x + 1)(x - 7) is the odd one.

Step-by-step explanation:

1) sum= 8

Product = 7

Factors = 1 , 7    {1*7 = 7  & 1+7 = 8}

x² + 8x + 7 = x² + x + 7x + 7

                 = x(x +  1) + 7(x + 1)

                 =(x +1 )(x + 7)

2) x² - 8x + 7 = x² -x -7x + (-1)*(-7)

                      = x(x - 1) - 7(x - 1)

                     =(x - 1)( x - 7)

3)Sum = 6

Product = -7

Factors = (-1) , 7   { -1 + 7 = 6   & (-1)*7 = -7}

x² + 6x - 7 = x² - x + 7x - 7

                   = x(x - 1) + 7(x - 1)

                   = (x  - 1)(x + 7)

Answer:

(x+1)(x-7) is the odd one out
