Answer:

t-5 = Ned's age

Step-by-step explanation:

t = teds age

Ted is 5 years older than Ned

t = Ned +5

Subtract 5 from each side

t-5 = Ned

t-5 = Ned's age

ted = 5 tears older than Ned.

ted = t years.

→ t = Ned's age + 5

→ Ned's age + 5 = t

→ Ned's age = t - 5

So,

Then, t - 5 = Ned's age.

Answer:

GK = 10x+1

GH = 16.4

HK = 20.6

Step-by-step explanation:

Given the expressions 4x+2=GH, 6x-1=HK and GK = 37, according to vector addition GH + HK = GK

Substituting the functions into the formula we will have:

GK = 4x+2 + 6x-1

collect like terms

GK = 4x+6x +2-1

GK = 10x+1

The algebraic expression that represents GK is 10x+1.

To get the value of x, since GK = 37

10x+1 = 37

10x = 37-1

10x = 36

x = 36/10

x = 3.6

Since GH =4x+2, substitute x = 3.6 into the function

GH = 4(3.6)+2

GH = 14.4+2

GH = 16.4

Also HK = 6x-1

HK = 6(3.6)-1

HK = 21.6-1

HK = 20.6

Hence the algebraic expression that represents GK is 10x + 1 and the value GH is 16.4, HK is 20.6

Answer:

875 ft³

Step-by-step explanation:

First, let's break it down into three different sections.

Starting with the cube on the bottom and then the rest of the Rectangular Prism.

The formula for Volume Cube  V = a³

The formula for Volume of Rectangular Prism:  V = lwh

From the picture we can see that the bottom is a cube with a lenght of 5 ft thus V = 5³ = 125 ft³

The second Rectangular Prism in the middle has a lenght of 20 ft (15 + 5), a width of 5 ft and a height of 5 ft. Use the formula above 20x5x5 = 500 ft³

The top  Rectangular Prism has a lenght & with of 5 ft and a height of 10 ft.

So again 5x5x10 = 250 ft³

Now all we need is to add them all together:

125 + 500 + 250 = 875 ft³

Answer:

b = sqrt(161)

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

8^2 + b^2 = 15^2

64 + b^2 = 225

Subtract 64 from each side

b^2 = 225-64

b^2 =161

Take the square root of each side

sqrt(b^2) = sqrt(161)

b = sqrt(161)

Answer:

[tex]sin\theta =\pm\dfrac{4}{5}\\tan\theta =\pm\dfrac{3}{4}[/tex]

Step-by-step explanation:

Kindly refer to the attached image of a right angled [tex]\triangle ABC[/tex].

Let [tex]\angle C = \theta[/tex]

Sides BC = a

AB = c and

AC = b respectively.

To prove:

[tex]sin^2\theta+cos^2\theta =1[/tex]

Proof:

Using Sine and Cosine values:

[tex]sin\theta =\dfrac{Perpendicular}{Hypotenuse}\\\Rightarrow sin\theta =\dfrac{AB}{AC} = \dfrac{c}{b }[/tex]

[tex]cos\theta =\dfrac{Base}{Hypotenuse}\\\Rightarrow cos\theta =\dfrac{BC}{AC} = \dfrac{a}{b}[/tex]

As per Pythagorean theorem:

[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow b^{2} = a^{2} + c^{2} .......... (1)[/tex]

Considering the LHS of [tex]sin^2\theta+cos^2\theta =1[/tex]:

[tex](\frac{c}{b})^2+(\frac{a}{b})^2\\\Rightarrow \frac{c^2+a^2}{b^2}[/tex]

Now, using equation (1):

[tex]\Rightarrow \dfrac{b^2}{b^2} = 1 = RHS[/tex]

Hence, proved that : [tex]sin^2\theta+cos^2\theta =1[/tex]

Now, we are given that:

[tex]cos\theta =\frac{4}{5}[/tex]

To find, sine and cosine values of the angle i.e. [tex]sin\theta = ?[/tex] and [tex]tan\theta = ?[/tex]

Using [tex]sin^2\theta+cos^2\theta =1[/tex]:

[tex]sin^2\theta+(\dfrac{4}{5})^2 =1\\\Rightarrow sin^2\theta = \dfrac{9}{25}\\\Rightarrow sin\theta = \pm \dfrac{3}{5}[/tex]

We know that:

[tex]tan\theta =\dfrac{sin\theta}{cos\theta}\\\Rightarrow tan\theta =\pm \dfrac{\dfrac{3}{5}}{\dfrac{4}{5}}\\\Rightarrow \bold{tan\theta =\pm \dfrac{3}{4}}[/tex]

Answer:

26.6°

Step-by-step explanation:

The area of a triangle is given by (1/2) * (base) * (height). The two triangles share the same height, so in order for the shaded triangle to have twice the area, its base must be twice that of the non-shaded triangle.

The non-shaded triangle is a right triangle with two 45° angles, so it's an isoceles right triangle with a base equal to its height.

This means that the height of the shaded triangle is 1/2 of its base. Knowing that we can get the angle of ACB with:

tan⁻¹(1/2) ≈ 0.4636476 (in radians)

Convert to decimal angle:

0.4636476 * (180/π) ≈ 26.6°

Answer:

[tex]y = 0.01092395604x^3[/tex]

Step-by-step explanation:

Given:

[tex]y = 0.000304x^3[/tex]

Where y is in pounds and x is in inches

Required

Represent y in kilogram and x in centimetre

[tex]y = 0.000304x^3[/tex]

The expression can be rewritten as

[tex](y\ pound) = 0.000304(x\ inch)^3[/tex]

------------------------------------------------------------------------------------------------

If [tex]0.394\ inch= 1\ cm[/tex]

Divide both by 0.394

[tex]\frac{0.394\ inch}{0.394}= \frac{1\ cm}{0.394}[/tex]

[tex]1\ inch= \frac{1\ cm}{0.394}[/tex]

[tex]1\ inch = 2.538\ cm[/tex] (Approximated)

Multiply both sides by x

[tex]x * 1\ inch = 2.538\ cm * x[/tex]

[tex]x \ inch = 2.538x\ cm[/tex]

------------------------------------------------------------------------------------------------

If [tex]2.20\ pound = 1\ kg[/tex]

Divide both by 2.20

[tex]\frac{2.20\ pound}{2.20} = \frac{1\ kg}{2.20}[/tex]

[tex]1\ pound = \frac{1\ kg}{2.20}[/tex]

[tex]1\ pound = 0.455\ kg[/tex] (Approximated)

Multiply both sides by y

[tex]y * 1\ pound = 0.454\ kg * y[/tex]

[tex]y \ pound = 0.454y\ kg[/tex]

------------------------------------------------------------------------------------------------

Substitute 0.455y kg for y pound and 2.538x cm for x inch in [tex](y\ pound) = 0.000304(x\ inch)^3[/tex]

[tex]0.454y = 0.000304(2.538x)^3[/tex]

[tex]0.454y = 0.000304(16.35x^3)[/tex]  Approximated

[tex]0.454y = 0.0049704x^3[/tex]

Divide both sides by 0.455

[tex]\frac{0.455y}{0.455} = \frac{0.0049704x^3}{0.455}[/tex]

[tex]y = \frac{0.0049704x^3}{0.455}[/tex]

[tex]y = 0.01092395604x^3[/tex]

The line crosses (1/2,0) and (0,4/7)

Let m be the slope of this line

● m = [0-(4/7)]/[(1/2)-0)]

● m = (-4/7)/(1/2)

● m = (-4×2)/7

● m = -8/7

So the slope of this line is -8/7

Answer:

28

Step-by-step explanation:

After substituting -2 for m and 5 for n, the original expression becomes:

|(-2)^2 - 7| + (5)^2, or

|4 - 7| + 25  or

|-3| + 25 = 28

Answer:

8.17.4 miles per 1 gallons 9. 2 miles per second.

Step-by-step explanation:

so you have yo divide 384 divided by 22 then boom.

Once again you have to divide 60 which is 1 hour (60 minutes is an hour) to the 32 miles. :)

Problem 8

-----------------------

Explanation:

You divide the number of miles over the number of gallons to get this result

384/22 = 17.45

Another way you could think of it is to say

384 miles = 22 gallons

Then you divide both sides by 22 getting

17.45 miles = 1 gallon

Showing that 1 gallon of gas gets you roughly 17.45 miles

=============================================

Problem 9

---------------------

Explanation:

Check out the attached diagram below. For the first column, I placed "32 miles" over "1 hour" to indicate "32 miles per hour". The second column is from the idea that 1 hour = 60 minutes. This helps us convert from hours to minutes. Note how the "hour" units cancel when we divide.

The third column helps us convert from minutes to seconds. We have the "minutes" units cancel out when they divide. It's important that one "minute" unit is on top, and the other is on the bottom. Finally, the last column helps us convert from miles to feet since 1 mile = 5280 feet.

Once this table formed, you multiply the numbers across the top to get 32*1*1*5280  = 168960

And you multiply everything along the bottom row: 1*60*60*1 = 3600

The last step is to divide the two results (top row over bottom row) getting

168960/3600 = 46.933 approximately

So 32 mph converts to roughly 46.933 ft per second.

Side note: the conversion method I used is called the "railroad method" or "railroad tracks method" as the table lines form what appears to be railroad tracks of sorts.

Area = 154 m²

Step-by-step explanation:

i pressume base = 14 m

height = 22 m

Area of a triangle = 1/2 * base * height

Area = 1/2 * 14 * 22

Area = 154 m²

The area of the triangle is given by the equation A = 154 m²

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

Given data ,

Let the area of the triangle be represented as A

Now , the value of A is

Let the height of the triangle be h

The value of h = 22 m

Let the base of the triangle be b

The value of b = 14 m

Now , area of the triangle = ( 1/2 ) x Length x Base

Substituting the values in the equation , we get

Area of the triangle A = ( 1/2 ) x 22 x 14

Area of the triangle A = 154 m²

Therefore , the value of A is  154 m²

Hence , the area of the triangle is  154 m²

Answer:

3, -2, -1, 0, 1, 2, 3

Step-by-step explanation:

Given the inequality expression |x| < 4 where x is unknown. To her the possible values of x, we must undeterstand that the absolute value of a number returns both positive and negative value.

Hence |x| can either return +x or -x

If x is positive, the inequality expression will be x<4.

If the value of x is negative, then -x<4

From -x<4

Multiply both sides by minus sign will change the sense of the inequality sign.

-(-x) > -4

x>-4

If x is greater than -4, then -4<x.

Combining both inequality will give;

-4 < x and x<4

-4<x<4

Hence the possible values of Javier's number are integers between -4 and 4.

The values are -3, -2, -1, 0, 1, 2, 3.

64

Step-by-step explanation:

Hello, we can write this two digit number 'ab', a and b being positive integer between 0 and 9.

For instance , 54, a = 5 and b =4

The number can be written 10*a+b (54=5*10+4, for instance)

The sum of a two digit number is 10.

a + b = 10

The value of the number is 16 times the units digit.

10a + b = 16b <=> 10a = 16b - b = 15b

[tex]<=> a = \dfrac{15}{10}b=\dfrac{3}{2}b=\dfrac{3}{2}(10-a)=15-\dfrac{3}{2}a\\\\<=> \dfrac{2+3}{2}a = 15\\\\<=> 5a=30 <=> a = 6[/tex]

and then, b = 10 - 6 = 4.

So the solution is 64.
