A father is 40 years older than his daughter. 3 years ago he was 5 times older from his daughters age. What are their current ages?

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

[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:

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

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:

y=-4

Step-by-step explanation:

(y+4)3-6y=2(4-2y)

(y)(3)+(4)(3)+-6y=(2)(4)+(2)(-2y)

3y+12+-6y=8+-4y

(3y-6y)+12=-4y+8

-3y+12=-4y+8

-3y+12+4y=-4y+8+4y

y+12=8

y+12-12=8-12

y=-4

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

Step-by-step explanation:

Midsegment is the half the length of the parallel side of the triangle.

So parallel sides of the triangles, which are the side of the base of the pyramid are:

Answer:

the length of the base of the pyramid =2×58=116

since the mid segment line from the midpoint is half of the third one or base.

Answer:

A = 226.08

Step-by-step explanation:

Assuming that you are  wrapping the sides of the cylinder and the circular top and bottom, then the formula for the surface area of the cylinder is:

A=2πrh+2πr^2 so substitute for each variable A=2(3.14)(3)(9) + 2(3.14)(3)^2

notice how I substituted 3 for the radius since it is 1/3 of 9 (the height)

Solving we get A = 169.56 + 56.52 = 226.08

Answer:

68.55

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

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.

Answer:

x=2

Step-by-step explanation:

First, you want to distribute -2 into both terms in the parenthesis.

-2(x-3) = -2x+6

Now you have -2x+6=-3x+8

Next, I want to only have x on one side of the equation to solve it, so I will add 3x to both sides.

x+6=8

Finally, I subtract 6 from both sides so x is alone on one side of the equation

x=2

Now I know x = 2. To double check this, I can substitute 2 in for x in the original equation.

-2(2 - 3) = -3(2) + 8

-2(-1) = -6 +8

2 = 2

Both sides equal eachother, so x = 2 is the correct solution.

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.
