Answer:

Square lot and 187500

Step-by-step explanation:

To find question number A, we can calculate the area of each lot. The square plot is:

2/5×2/5=4/25

The first one is

2/3×3/8=1/4

Then we can make both have the same denominator:

1/4=25/100, 4/25=16/100

That means that the square lot is bigger.

We know that the area is 1/4 square mile. So it's 1/4 of 750,000

That's

1/4×750000=187500

Hope that helps! :)

Answer:

8000 (Estimated) and the real difference would be 7934

Step-by-step explanation:

An estimated difference would be 8000, we get this number by subtracting 23,000 from 31,000 to make the subtraction much faster. The real answer to this would be 7934 which is pretty close to 8000 which is the estimation

Answer:

7/8 ÷ 2/8 = 3 1/2

Step-by-step explanation:

When we divide two fractions, such as 7/8 ÷ 2/8, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.

The quotient obtained from the division of given fractions is 7/2.

Given that, 7/8 divided by 2/8.

Dividing fractions is nothing but multiplying the fractions by reversing one of the two fraction numbers or by writing the reciprocal of one of the fractions. By reciprocal we mean, that if a fraction is given as a/b, then the reciprocal of it will b/a.

Here, 7/8 ÷ 2/8

= 7/8 × 8/2

= 7/2

Therefore, the quotient obtained from the division of given fractions is 7/2.

Answer:

a = 10

d = 5

Step-by-step explanation:

[tex]a_{n}=a + (n-1)d\\\\a_{5}=30\\\\a + (5-1)*d=30\\\\[/tex]

a + 4d = 30 ------------------(I)

[tex]a_{13}=70\\\\a + (13-1)d=70[/tex]

a + 12d =70 -------------(II)

Multiply equation (II) by (-1) and then add.So, 'a' will be eliminated and you can find the value of d

(I)         a +   4d = 30

(II)*(-1)   -a - 12d = -70   {Now add}

               - 8d   =  - 40

Divide both sides by (-8)

d = -40/-8

d = 5

Plugin d = 5 in equation (I)

a + 4*5 = 30

a + 20 = 30

a = 30 - 20

a = 10

(a) Slope is rise over run, or change in y over change in x.

1 -> 3 ( [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{4 - -8}{-1 - -5} = \frac{4 + 8}{-1 +5}= \frac{12}{4} =\frac{12}{4}[/tex] )

2 -> 3 ( [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{1 - 7}{0 - 2} = \frac{-6}{- 2} =\frac{6}{2}[/tex] )

3 -> -1/3 ( [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{-7 - -3}{6 - -6}= \frac{-7+3}{6+6}=\frac{-4}{12}=-\frac{1}{3}[/tex] )

(b) If a line is parallel, the slopes will be the same. If they are perpendicular, the slopes will be are negative reciprocals of one another. If they are neither, then their slopes don't match up in any way.

1 & 2 -> Parallel

1 & 3 -> Perpendicular

2 & 3 -> Perpendicular

     Note - Since 1 & 2 are parallel, then both 1 and 2 will be perpendicular to 3!

Answer:

Line 1: slope: 1

Line 2: slope: -3/2

Line 1 and line 2: neither

Line 3 slope: - 1/3

Line 1 and 3: neither

Line 2 and 3: neither

Step-by-step explanation:

Line 1: (-5,-8) and (-1,4)

Slope: (4 - - 8)/(-1 - - 5) = 12/4 = 3

Line 2: (2,7) and (0,10)

Slope: (10 -7)/(0 - 2) = 3/-2 = -3/2

Line 3. ((-6,-3) and (6,-7)

Slope: (-7 - - 3)/(6 - -6)= -4/12= -1/3

Step-by-step explanation:

The probability of obtaining a red marble in one sample is 5/11. Since you are sampling twice the probability of picking a red marble both times is 5/11 x 5/11 = 25/121. That is slightly less than one time in five.

Answer:

Step-by-step explanation:

1) Area of triangle= 1/2 x b x h

b = 7.6cm h= 3.4cm

Area= 1/2 x 7.6 x3.4 = 12.92cm²

2)Divide the shape into a triangle and a rectangle

Area of rectangle : l x b

L= 20cm, b= 7cm

= 20 x 7 = 140 cm²

Area of triangle =1/2 x b xh

B = 20cm, h= 16 - 7 = 9cm

1/2 x 20x 9= 90cm²

Total area = 140 + 90 = 230cm²

3) area of triangle = 1/2 x b x h

B = 12cm, h= 5cm

= 1/2 x 12 x 5 = 30cm²

4) area of triangle = 1/2 x b x h

B = 15cm, h= 8cm

= 1/2 x 15 x 8 = 60cm²

5) divide the shape into two rectangles; the lower and the upper

Area of rectangle= l x b

Upper rectangle, l= 10cm, b= 27 - 9 = 18cm

Area= 10 x 18= 180cm²

Lower rectangle, l= 24cm, b= 9cm

Area = 24 x 9= 216cm²

180 + 216 = 396cm²

Answer: C

Step-by-step explanation: the key is to look at the relationships between the numbers. The y value increments by 5.5 or 5 respectively, which LOOKS like additive. However, it is actually multiplicitve, since the question is the relation between X and y, not the y values. From there you can simply test that 5x1=5, 5x2=10, etc, etc.

Angle A and B are shown to be the same which means the 2 sides are the same. Using the 2 sides solve for x.

2x -24 = x-2

Add 24 to both sides

2x = x + 22

Subtract x from both sides:

X = 22

Bc = x , so BC = 22

Step-by-step explanation:

Since the base angles are the same, SV and TV must be the same length
