Five workers dig a trench 5 yards long in 5 hours. How many workers are needed to dig a 100 yards long in 100 hours?

Answer:

The answer is SAS. ( Option C )

Step-by-step explanation:

S A S congruence theorem is used to prove △MNP ≅ △ABC.

Given △MNP and △ABC are connect between points B and M.

In △MNP and △ABC

Side PN = Side BC (given)

angle PNM = angle ABC (given)

Side NM = Side AB (since AM and BN are congruent so NM and AB are also congruent)

So, by Side Angle Side Congruence rule  △MNP ≅ △ABC.

Hence S A S congruence theorem is used to prove △MNP ≅ △ABC.

Answer:

27/16 chapters completed in 1.5 hours

Step-by-step explanation:

Jeff read 3/8 part in minutes = 20

He read complete chapter in minutes =[tex]\frac{20}{\frac{3}{8}}=\frac{20}{3} \times 8 = \frac{160}{3} minutes[/tex]

60 minutes = 1 hour

[tex]\frac{160}{3} minutes = \frac{160}{3} \times \frac{1}{60}=\frac{8}{9} hours[/tex]

So, No. of chapters completed in[tex]\frac{8}{9}[/tex] hours = 1

No. of chapters completed in 1.5 hours = [tex]\frac{1}{\frac{8}{9}} \times 1.5=\frac{27}{16}[/tex]

Answer:

80°

Step-by-step explanation:

SPO+OPA+APC= 180°

(Angles on a straight line sum up to 180)

60+OPA+40=180

OPA=180-100

=80°

So, BPU is also 80°

(Vertically opposite angles are always equal)

Answer:

80⁰

Step-by-step explanation:

SPU = CPR = 40⁰ ( vertically opposite)

BPU + 40 + 60 = 180⁰ (straight line angle)

BPU = 180 - 100

BPU = 80⁰

Perimeter of the parallelogram EFGH is 11.76 units

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length.

A parallelogram is a simple quadrilateral with two pairs of parallel sides.

Given,

The coordinates of the parallelogram = E(1,3), F(0,2), G(4,0) and H(5,1)

We know that,

In parallelogram EF=HG and EH=FG

Perimeter of the Parallelogram = 2(a + b)

Distance between EF = a = [tex]\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1}})^{2} }[/tex]

[tex]=\sqrt{(0-1)^{2} +(2-3)^{2} }\\=\sqrt{1+1} \\=\sqrt{2}[/tex]

a =1.41 units

Distance between EH = b =[tex]\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1}})^{2} }[/tex]

[tex]=\sqrt{(5-1)^{2} +(1-3)^{2} }\\=\sqrt{16+4} \\=\sqrt{20}[/tex]

b =4.47 units

Perimeter of the Parallelogram = 2(a + b)

=2(1.41+4.47)

=11.76 units

Hence,  the Perimeter of the Parallelogram EFGH is 11.76 units

Answer:

1875 square miles

Step-by-step explanation:

There are a total of 10 women and 3 men. Let's define two variables:

Given that they inherited a 30000 (square miles) of land and that each brother has inherited double what each sister has inherited, we can establish the next equations:

2*w = m

10*w + 3*m = 30000

Replacing the first equation into the second one, and solving for w:

10*w + 3*2*w = 30000

16*w = 30000

w = 30000/16

w = 1875 square miles

Your mom, and all of her sisters, inherited 1875 square miles each

Answer:

-3/5

Step-by-step explanation:

The slope of a perpendicular line is always the negative reciprocal of the slope of the original line.

1/(5/3) * - 1 =  -3/5

The slope of the line that is perpendicular to the graph of y = 5/3 x + 8 is -3/5.

Equation of a line in slope intercept form is y = mx + b, where m is the slope of the line and b is the y intercept, which is the y coordinate of the point where it touches the Y axis.

Given a line,

y = 5/3 x + 8

Comparing with the slope intercept form,

Slope of the given line = 5/3

Any line perpendicular to the given line has a slope which is the negative reciprocal.

Slope of the perpendicular line = -3/5

Hence the required slope is -3/5.

Answer:

1595 ft^2

Step-by-step explanation:

The answer is obtained by adding the areas of sectors of several circles.

1. Think of the rope being vertical going up from the corner where it is tied. It goes up along the 10-ft side. Now think of the length of the rope being a radius of a circle, rotate it counterclockwise until it is horizontal and is on top of the bottom 20-ft side. That area is 3/4 of a circle of radius 24.5 ft.

2. With the rope in this position, along the bottom 20-ft side, 4.5 ft of the rope stick out the right side of the barn. That amount if rope allows for a 1/4 circle of 4.5-ft radius on the right side of the barn.

3. With the rope in the position of 1. above, vertical and along the 10-ft left side, 14.5 ft of rope extend past the barn's 10-ft left wall. That extra 14.5 ft of rope are now the radius of a 1/4 circle along the upper 20-ft wall.

The area is the sum of the areas described above in numbers 1., 2., and 3.

total area = area 1 + area 2 + area 3

area of circle = (pi)r^2

total area = 3/4 * (pi)(24.5 ft)^2 + 1/4 * (pi)(4.5 ft)^2 + 1/4 * (pi)(14.5 ft)^2

total area = 1414.31 ft^2 + 15.90 ft^2 + 165.13 ft^2

total area = 1595.34 ft^2

Answer:

B. 3

Step-by-step explanation:

→You need to get rid of the (-x + 4) in the denominator, and to do so, you must multiply both sides by it:

[tex]\frac{2x-3}{-x+4} =3[/tex]

2x - 3 = 3(-x + 4)

→Distribute the 3 to (-x + 4):

2x - 3 = -3x + 12

→Add 3x to both sides:

5x - 3 = 12

→Add 3 to both sides:

5x = 15

→Divide both sides by 5:

x = 3
