Step-by-step explanation:

Answer: Charity is 36 years old today.

Step-by-step explanation:

Let x = Present age of daughter.

Age of Charity = 4x

Age of her husband = 4x+6

After 10 years,

Age of daughter = x+10

Age of Charity = 4x+10

Age of her husband = 4x+6+10=4x+16

As per given,

[tex]x+10+4x+10+4x+16=117[/tex]

[tex]9x+36=117\\\\ 9x=117-36\\\\ 9x=81\\\\ x=9[/tex]

Present age of Charity = 4(9)=36 years

Hence, Charity is 36 years old today.

Answer:

Proved

Step-by-step explanation:

The options are not given. So, I will solve from scratch

Given

[tex]\frac{secx-1}{tan x}= \frac{tanx}{secx+1}[/tex]

Required

Prove

Multiply the right-hand side by [tex]\frac{secx + 1}{secx + 1}[/tex]

[tex]\frac{secx-1}{tan x} * \frac{secx + 1}{secx + 1}= \frac{tanx}{secx+1}[/tex]

Apply difference of two squares on the numerator

[tex]\frac{sec^2 x - 1}{(tanx)(secx + 1)} =\frac{tanx}{secx+1}[/tex]

In trigonometry:

[tex]tan^2x = sec^2x - 1[/tex]

So, we have:

[tex]\frac{tan^2 x}{(tanx)(secx + 1)} =\frac{tanx}{secx+1}[/tex]

[tex]\frac{tan x * tan x}{(tanx)(secx + 1)} =\frac{tanx}{secx+1}[/tex]

tan x cancels out

[tex]\frac{tan x}{secx + 1} =\frac{tanx}{secx+1}[/tex]

Answer:

[tex]Ratio = 3: 2[/tex]

Step-by-step explanation:

Given

Shape: Cube

[tex]L = 8cm[/tex]

The surface area is calculated as:

[tex]Area = 6*L^2[/tex]

[tex]A_1 = 6*8^2[/tex]

[tex]A_1 = 384[/tex]

When it is cut by half; the length is affected; so, it forms a cuboid of the following dimension:

[tex]L = \frac{8}{2} = 4[/tex] --- Length

[tex]W = 8cm[/tex] --- Width

[tex]H = 8cm[/tex] --- Height

The surface area is:

[tex]Area = 2 *(L*W + H * L + W * H)[/tex]

[tex]A_2 = 2 *(4*8 + 8 *4 + 8 * 8)[/tex]

[tex]A_2 = 2 *128[/tex]

[tex]A_2 = 256[/tex]

So, the ratio of surface area is:

[tex]Ratio = A_1 : A_2[/tex]

[tex]Ratio = 384 : 256[/tex]

Divide by 128

[tex]Ratio = 384/128 : 256/128[/tex]

[tex]Ratio = 3: 2[/tex]

Answer:

Answer:

18 stamps

Step-by-step explanation:

3/5(30) = 90/5 = 18

Answer:

Step-by-step explanation:

The chart tells you Zack has 30 stamps in total.

3/5 are animal stamps.

So you do

30 x 3/5 = 90 / 5 = 18

OR

30 / 5 x 3 = 6 x 3 = 18

Answer: 45 miles per hour

Step-by-step explanation:

Answer: if you are trying to find the hourly rate it's 45/hr. If your looking for minute rate it's .75/min. If you are looking for seconds rate it's .0125/sec

Step-by-step explanation: divide 135 by 3 for hourly rate. Divide 45 by 60 for minute rate. Divide .75 by 60 to to get seconds rate.

Answer:

Approximately [tex]5.7[/tex] inches

Step-by-step explanation:

The crossbar and two given lengths form a right triangle. We know this because we see a right angle marked on the diagram in between the two given sides.

In this case, we have a right triangle with legs of [tex]4[/tex] and [tex]4[/tex], and we need to find the hypotenuse. By the Pythagorean Theorem ([tex]a^{2} +b^{2} =c^{2}[/tex], where [tex]a[/tex] and [tex]b[/tex] are the legs and [tex]c[/tex] is the hypotenuse), we get:

[tex]4^{2} +4^{2} =c^{2}[/tex]

[tex]16+16=c^{2}[/tex] (Evaluate exponents)

[tex]32=c^{2}[/tex] (Combine like terms)

[tex]\sqrt{32}=\sqrt{c^{2}}[/tex] (Take the square root of both sides of the equation to get rid of [tex]c[/tex]'s exponent)

[tex]c=4\sqrt{2} ,c=-4\sqrt{2}[/tex]

The latter solution is an extraneous solution because the side lengths of a triangle cannot be negative. Therefore, the answer is [tex]4\sqrt{2} \approx 5.7[/tex] inches. Hope this helps!

Answer:

It is only a solution to y = x - 2, not -3x - 2y = -8

Step-by-step explanation:

I) Check y = x - 2:

y = x - 2

2 = 4 - 2

As you can see, (4, 2) is a solution to this system.

II) Check -3x - 2y = -8:

-3x - 2y = -8

(-3)(4) - (2)(2) = -8

-12 - 4 =/= 8

-12 - 4 = -16, not 8. So (4, 2) is not a solution to this system.

Answer:

Answer:

2x + 21

Step-by-step explanation:

Given :

Plant 1 : production level) 5x + 17

Plant 2 : production level = 3x - 4

To how much more plant 1 produces than plant 2 ; subtract production of plant 2 from plant 1

(5x + 17) - (3x - 4)

Open the bracket

5x + 17 - 3x + 4

5x - 3x + 17 + 4

2x + 21

Answer:

80in²

Step-by-step explanation:

Hey There!

So the first step of this problem is to find the width of the scale drawing

To do so we need to find the scale factor

To find the scale factor we divide the length of the room by the length of the scale factor

32/8=4

so the scale factor is 4

now to find the width

40/4=10

so the width of the scale drawing is 10 in

now we can find the area given the length and the width

10x8=80in²

so we can conclude that the area of the scale drawing is 80in²

Answer:

£9.80

Step-by-step explanation:

The computation of the total value is shown below:

Given that

The value of 20p coins is £2.80

So the value of 50p would be

= £2.80 × 50 ÷ 20

= £7

Now the total value is

= £2.80 +  £7

= £9.80
