Answer:

-8.66666667 feet because:

Step-by-step explanation:

-2 1/3 x 3 = 7

-2 1/3 ÷ 2 = 1.66666666667

7 + 1.6666666667 = 8.66666667

Answer:

Step-by-step explanation:

Each plane has a starting altitude and a fixed rate of climb. Its altitude at some time t will be the sum of the starting altitude and t times the rate of climb.

__

  altitude = starting altitude + t × rate of climb

  a(t) = 4000 +35.25t

  b(t) = 2427 +65.5t

The planes will be at the same altitude at the same time when ...

  a(t) = b(t)

  4000 +35.25t = 2427 +65.5t

  1573 = 30.25t . . . . . . . . . . subtract 2427+35.25t

  52 = t . . . . . . . . . . . . . divide by 30.25

That altitude is ...

  a(52) = 4000 +35.25×52 = 4000 +1833 = 5833

52 seconds will pass before the planes are at the same altitude.

Their altitude then will be 5833 feet.

The value of AB id 0.5 unit.

The Angle-Angle-Angle (AAA) criterion for the similarity of triangles states that “If in two triangles, corresponding angles are equal, then their corresponding sides are in the same ratio (or proportion) and hence the two triangles are similar”.

Any pair of angles each of which is on the same side of one of two lines cut by a transversal and on the same side of the transversal are called corresponding angles and they are always equal.

According to the given question.

A, B and C lie on the straight line segment. and A, E, and D are also lie in the straight line segment.

Also, BE = 1.75m, CD = 7m and BC = 1.5m

Now, in ΔAEB and ΔADC

EB is parallel to BC

So,

∠AEB ≅ ∠ADC   (corresponding angles)

∠ABE ≅ ∠ACD   (corresponding angles)

∠EAB ≅ ∠DAC    (common angle to the both triangle)

Hence, by AAA Similarity rule

ΔAEB is similar to ΔADC

Therefore,

[tex]\frac{AE}{AD} =\frac{BE}{CD} =\frac{AB}{AC}[/tex]         (sides of the similar triangles are in proportion)

So,

[tex]\frac{BE}{CD} =\frac{AB}{AC} \\\implies \frac{AB}{AC} =\frac{1.75}{7} ....(i)[/tex]

Now, AC = AB + BC   (as, A, B, and C lie on a straight line)

[tex]\implies \frac{AB}{AB+BC} =\frac{1.75}{7}[/tex]       (from (i))

[tex]\implies \frac{AB}{AB+1.5} =\frac{1.75}{7}[/tex]

[tex]\implies 7AB = 1.75AB + 1.75(1.5)[/tex]

[tex]\implies 7AB -1.75AB = 2.625[/tex]

[tex]\implies 5.25AB = 2.625[/tex]

[tex]\implies AB = \frac{2.625}{5.25} = 0.5[/tex]

Hence, the value of AB id 0.5 unit.

Step-by-step explanation:

Answer:

5/12 (corrected)

Convert with lowest common denominator, 12(find by multiplying)

1/3 = 4/12

1/4 = 3/12

Add the fraction's numerators

4 + 3 = 7

Subtract by 1 whole

7/12 - 12/12 = 5/12

Thus, your answer is 5/12

Answer:

5/12

Step-by-step explanation:

to give the fractions the same denominator, find their gcm

3 * 4 = 12

therefore multiply 1/3 by 4/4 to get 4/12

multiply 1/4 by 3/3 to get 3/12

3/12 + 4/12 = 7/12

to find the remainder subtract

12/12 - 7/12 = 5/12

your answer is 5/12

Answer:

Step-by-step explanation:

let C' be the bigger circle

and C be the smaller circle and r its radius.

Area(C') = π × (9² -  r²)

Area(C) = π × r²

Area(shaded region) = area(C') - area(C)

                                  = π × (9² -  r²)

the statement “the area of the shaded region is twice that of the smaller circle ” means  π × (9² -  r²) = 2 × π × r²

Now, let’s solve the equation:

π × (9² -  r²) = 2 × π × r²

⇔ π × (9² -  r² - 2r²) = 0

⇔ π × (81 -  3r²) = 0

⇔ 81 -  3r² = 0

⇔ 81 = 3r²

⇔ r² = 27

⇔ r = √27

⇔ r = 3√3

Answer:

6.32

Step-by-step explanation:

Area of bigger circle = π(9)² = 81π cm²

Area of smaller circle = π(9)²/2 = 81π/2 = 40.5πcm²

Area scale factor = (Linear Scale factor)²

81π/40.5π = 9²/x² {cancel the π}

81/40.5 = 81/x² (cross multiplication)

81x² = 40.5 × 81

√x² = √40.5 (square root both sides)

x = 6.32
