10. A freight train leaves a station and travels at a rate of 30 miles per hour. Two hours later, an express train leaves
the same station traveling in the same direction at a rate of 50 miles per hour. In how many hours will the express train
overtake the freight train?

The picture is not clear... the Question has got cut at the sides .... please take the picture properly and the post the Question again... please

[tex]\\\\\huge\underline\mathbb\pink{ANSWER:}\\\\[/tex]

No they are not unequal... i. e. the two wires A and B are equal .

[tex]\frac{1}{3}[/tex] of A = [tex]\frac{1}{3}[/tex] of B

=> [tex]\frac{3}{3}[/tex] × A = B

=> 1 × A = B

=> A = B

:. The length of A = the length of B .

Answer:

$13.5

Step-by-step explanation:

Given data

We are given that the tax per CD is  $1.30

Hence for the 3 CDs the total tax = 3*1.3= $3.9

Also, the cost of the three CDs before tax = 44.4-3.9

=$40.5

Hence the cost of each CD before tax is

=40.5/3

=$13.5

The two triangles he drew and also the calculations he did are missing, so i have attached them.

Answer:

His calculations are not correct

Step-by-step explanation:

From the attached image showing the triangle, we can see that for the smaller triangle with w, 5.5 and 45° angle, it is clear that;

Opposite side is 5.5

Adjacent side is w

And angle is 45°.

Hypotenuse is unknown

Thus, from trigonometric ratios;

Opposite/adjacent = tan (angle)

Thus;

5.5/w = tan 45°

In Skylar's calculation, he expressed it as; 5.5/w = sin 45°

Therefore, his calculation is wrong.

Secondly, for the bigger triangle, it is clear that;

Opposite side is 5.5

Adjacent side is w + x

And angle is 35°.

Hypotenuse is unknown

Thus;

5.5/(w + x) = tan 35°

Whereas,skylar expressed his own as;

5.5/(w + x) = sin 35°

Again his calculation is wrong.

Answer:

peen

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let all the measurements be in same unit.

200 cm = 2 m

2000 mm = 2 m

Let distance jumped by Jack = x m

Distance jumped by Jerzy = x + 2

Distance jumped by Abdullah = (x+ 2) + 2 = x + 4

Total = 12.69 m

x + x +2 +x +4 = 12.69

x +x + x + 2 + 4 = 12.69

         3x + 6      = 12.69

                  3x = 12.69 - 6

                 3x  = 6.69

                    x = 6.69/3

                    x = 2.23 m

distance jumped by Jack =2.23m

Distance jumped by Jerzy = 2.23 + 2 = 4.23 m

Distance jumped by Abdullah = 2.23 + 4 = 6.23 m

Required Question:

Which number in the list is the greatest?

Answer:

25 yards

Step-by-step explanation:

Given

[tex]Distance:2\ 21\ 4\ 3\ 25[/tex]

Required

The greatest distance moved

To do this, we make comparison between the 5 distances given and select the greatest.

By comparison:

[tex]25 > 2[/tex]

[tex]25 > 21[/tex]

[tex]25 > 4[/tex]

[tex]25 > 3[/tex]

Hence, the greatest distance is 25 yards

Answer:

a. Perimeter of the figure = 80 units

b. Area of the figure = 480 square units

Step-by-step explanation:

Length of side of octagon

[tex] =2\sqrt {13^2 - 12^2} [/tex]

[tex] =2\sqrt {169 - 144} [/tex]

[tex] =2\sqrt {169 - 144} [/tex]

[tex] =2\sqrt {25} [/tex]

[tex] =2\times 5[/tex]

[tex] =10\: units[/tex]

a. Perimeter of the figure = 8*10 = 80 units

b. Area of the figure

[tex] = 8 \times \frac{1}{2} \times 10 \times 12 \\ \\ = 4 \times 120 \\ \\ = 480 \: {units}^{2} [/tex]

Answer:

114×10^5..............

Using the formulas

AB=s(s﹣a)(s﹣b)(s﹣c)

V=ABh

s=a+b+c

2

Solving for V

V=1

4h﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=1

4·12·﹣184+2·(18·18)2+2·(18·2)2﹣184+2·(18·2)2﹣24≈215.66641

or 216.

Step-by-step explanation:

C= 2πr

C=2 x 3.14 x 7.5 = 47.1 (Divide by 2 for half circle)

47.1 ÷ 2 = 23.55 + 15 + 15 + 15 = 68.55

Your Answer is C

Answer:

y > - (4/3) x - 3

Step-by-step explanation:

use (y2-y1)/(x2-x1) for slope, which is negative (use two points given, (-6, 5) and (3, -7))

y intercept is -3, but you can plug in values for x and y in any of two points given: (-6, 5) and (3, -7)

Then, dashed line indicates values along line are not included in inequality relationship

since shaded region is above line, the inequality uses ">"

Answer:

91.7 inches to 1 decimal place

Step-by-step explanation:

We will use Pythagoras's theorem to find the height of the pyramid.

The height of the Pyramid forms a right-angled triangle with half of the base and the slant height.

We can get half the length of the base by dividing the length of one side of the base = 20.4 by 2 = 10.2in

slant height = 92.3in

Therefore height = [tex]\sqrt{92.3^{2} -10.2^2} =91.73in[/tex]

The height of the pyramid is 91.73inches to 1 decimal place
