Answer:

The straight-line distance (in paces) from the tree to the treasure is 80.62 paces

Step-by-step explanation:

Given:

Distance walked towards the north = 70 Paces

Distance walked towards the East = 40 Paces

To Find:

The straight line distance  from the tree to the treasure =?

Solution:

We we track the trail we can find a right triangle formed where the two sides are 70 pace and 40 pace each. The straight line distance is the hypotenuse of the triangle(Refer the figure below

Now we can find the length of the hypotenuse by Pythagorean theorem

[tex]a^2 =b^2 +c^2[/tex]

where b and c are the sides of the triangle

and a is the hypotenuse

[tex]a^2 = 70^2 +40^2[/tex]

[tex]a^2 =4900 + 1600[/tex]

[tex]a = \sqrt{4900 + 1600}[/tex]

[tex]a =\sqrt{6500}[/tex]

a =  80.62

Final answer:

The additive inverse of – 4 is 4 because when – 4 is added to 4, the result is 0. This demonstrates the concept of additive inverses in algebra, where each number has a counterpart that sums to zero.

Explanation:

The question is asking to find the additive inverse or opposite of – 4. The additive inverse of a number is the number that, when added to the original number, results in a sum of zero. This is a fundamental concept in algebra and mathematics in general. To find the additive inverse of – 4, you simply need to find a number that, when added to – 4, equals 0.

The additive inverse of – 4 is 4. This is because – 4 + 4 = 0. When you add – 4 and its additive inverse together, their sum is 0, which means 4 is the correct answer. The concept of the additive inverse is crucial in equations solving and other algebraic manipulations, assisting in understanding how to balance equations and solve for unknowns.

Answer: OPTION C.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Whrere "m" is the slope and "b" is the y-intercept.

The line intersects the y-axis when [tex]x=0[/tex], therefore, you can identify from the given table that "b" is:

[tex]b=3[/tex]

Now, in order to find the slope of that line, you can follow these steps:

1. Substitute the value of "b" and the coordinates of any point from the table and into  [tex]y=mx+b[/tex]

2. Solve for "m".

Then, choosing the point (1,1), you get:

[tex]1=m(1)+3\\\\1-3=m\\\\m=-2[/tex]

Therefore, you can determine that the equation of that line in Slope-Intercept form, is:

[tex]y=-2x+3[/tex]

The value of [tex]sin100.sin120.sin140.sin160[/tex] is [tex]0.1875[/tex]

Step-by-step explanation:

To find the value of [tex]sin100.sin120.sin140.sin160[/tex], let us find the value of each angle.

The value of [tex]sin100=0.9848[/tex]

The value of [tex]sin120=\frac{\sqrt{3} }{2}[/tex]

The value of [tex]sin140=0.6428[/tex]

The value of [tex]sin160=0.3420[/tex]

Substituting the values of sin, we get,

[tex]sin100.sin120.sin140.sin160=0.9848*\frac{\sqrt{3} }{2} *0.6428*0.3420[/tex]

Multiplying the values of sin, we get,

[tex]sin100.sin120.sin140.sin160=0.1875[/tex]

Thus, the value of [tex]sin100.sin120.sin140.sin160[/tex] is [tex]0.1875[/tex]

The lengths of the sides of the triangle are 6 m, 6 m, and 8 m.

The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.

Let the length of the first side and 2nd side are x,

Two sides of a triangle have the same length.

The third side measures 4 m less than twice the common length.

So the length of the third side = 2x - 4

Given that the perimeter of a triangle is 20 m

Since the perimeter of a triangle is the addition of the lengths of the triangle's three sides.

So the perimeter of a triangle = sum of all sides

⇒ x + x + 2x - 4 = 20

⇒ 4x = 24

⇒ x = 6

So the length of the third side = 2(6) - 4 = 8

Hence, the lengths of the sides of the triangle are 6 m, 6 m, and 8 m.

Final answer:

To find the lengths of the triangle's sides, we establish a variable x for the two identical sides. The equation 4x - 4 = 20 is solved to give x = 6. Thus, the triangle has sides of 6 meters, 6 meters, and 8 meters.

Explanation:

The question is asking to determine the lengths of the three sides of a triangle when two of the sides have the same length, and the third side is 4 meters shorter than twice the length of the other two sides. Additionally, it is given that the perimeter of the triangle is 20 meters.

Let's denote the common length of the two sides as x meters. Hence, the length of the third side would be 2x - 4 meters. Since the perimeter of the triangle is the sum of its sides, we have the following equation:

x + x + (2x - 4) = 20

This simplifies to:

4x - 4 = 20

Adding 4 to both sides gives:

4x = 24

Dividing by 4 gives:

x = 6

Therefore, the lengths of the two identical sides of the triangle are 6 meters each, and the length of the third side is 2(6) - 4 = 8 meters.

The equation of g(x) is g(x) = 6x + 11

Step-by-step explanation:

Let us revise some transformation

∵ f(x) = 2x + 5

∵ The graph of f(x) is stretched vertically by scale factor 3

- That means multiply f(x) by 3

∴ The equation of the new graph is 3(2x + 5)

∵ The new graph is translated 4 units down

- That means subtract 4 from 3(2x + 5)

∴ The equation of g(x) is g(x) = 3(2x + 5) - 4

- Simplify the equation of g(x)

∴ g(x) = 3(2x) + 3(5) - 4

∴ g(x) = 6x + 15 - 4

- Add the like terms in the right hand side

∴ g(x) = 6x + 11

The equation of g(x) is g(x) = 6x + 11

[tex]a \times b = 0.24\\b = \frac{0.24}{a} or, a = \frac{0.24}{b}[/tex].

In the above equation the proper values can not be found only when the denominator will be 0.

As for example, if a = 2, then b = 0.12.

If a = 0.12, then b = 2.

If a = 1, b = 0.24 or b = 1, a = 0.24.

Thus, a or b can be any real number rather than 0.

Answer:

x = 76°

Step-by-step explanation:

At point I

to get angle JID

angle JID + 107° = 180°. (angle on a straight line)

angle JID = 180° - 107°

angle JID = 73°

for Triangle JiD

angle DJI + 31° + 73° = 180° (Sum of angles in a triangle)

angle DJI = 180 - 104 = 76°

angle FJI = 31 + 73 =104°. ( Sum of two interior angles in a triangle is equal to one exterior angle)

Hence,

x° + 104° = 180° (angle on a straight line)

x = 76°

Answer:

Karen had 45 m and m's candy.

Step-by-step explanation:

Let the number of m and m's candy be 'x'.

Now given:

Karen gave an equal amount of m and m's to herself and four friends.

So we can say that;

Number of people m and m's candy distributed equally = 5

Also Given:

Each person receives m and m's equivalent to the largest one digit number.

Now we know that;

Largest one digit number is 9.

So we can say that;

Each person receives m and m's = 9

We need to find number of m and m's Karen have.

Solution:

So we can say that;

Total number of m and m's Karen have is equal to Number of people m and m's candy distributed equally multiplied by number of m and m's can each person receives.

framing in equation form we get;

Total number of m and m's Karen had = [tex]9\times5 = 45[/tex]

Hence Karen had 45 m and m's candy.

Here is the answer based on your question

W (Bottled water) = 7/2$

N (Cheese Nachos) = -1/2$

Step-by-step explanation:

2W + 3N = $5.50

3W + 2N = $9.50

Find the common number and subtract them. In order to find isolate the water bottles or nachos. I will do water bottles

15 (2W + 3N = $5.50)

10 (3W + 2N = $9.50)

30w + 45N = $82.5

Minus

30W + 20N = $90

= 25N = -12.5

N = -1/2$

Substitute for N

3W + 2(-1/2) =9.5

3w -1 = 9.5

3w - 10.5

w = 7/2$

3/10 = 30/100 after multiplying top and bottom by 10

so we have 30/100 + 62/100 = (30+62)/100 = 92/100

Reduce this fraction

92/100 = (23*4)/(25*4) = 23/25

Therefore, 3/10+62/100 = 23/25

The core of calculus in mathematics are functions. The unique varieties of relations are the functions.

The cost of 1 salad exists $3.

A function is a relationship between a set of inputs and a set of potential outputs, where each input is associated to exactly one outcome.

A function from a set X to a set Y in mathematics assigns each element of X exactly one element of Y. The set X is known as the function's domain, while the set Y is known as the function's codomain.

Let, the cost of 1 sandwich be 'x' and the cost of 1 salad is 'y'.

4 sandwiches = 4x

3 salads = 3y

total spent = $24

From the given equation, we get

4x + 3y = 24

If each sandwich costs $3.75,

⇒ 4(3.75) + 3y = 24

simplifying the above equation, we get

⇒ 15 + 3y = 24

⇒ 3y = 24 - 15

⇒ 3y = 9

⇒ y = 9/3

⇒ y = 3

Therefore, the cost of 1 salad exists $3.

Answer:

On the blueprint the dimensions are 48 inches by 64 inches.

Step-by-step explanation:

Given:

The scale on blueprint was 1/4 inch = 1 foot.

The actual dimensions of her bedroom are 12 feet by 16 feet.

Now, to find the dimensions on the blueprint.

Let the dimensions on the blueprint be [tex]x[/tex] by [tex]y.[/tex]

As, given the scale on blueprint:

[tex]\frac{1}{4}\ inch=1\ foot[/tex]

So, [tex]\frac{1}{4}\ inch[/tex]  is equivalent to 1 foot.

Thus, [tex]x[/tex] is equivalent to 12 feet.

And, [tex]y[/tex] is equivalent to 16 feet.

Now, solving by cross multiplication method:

[tex]\frac{\frac{1}{4}}{1} = \frac{x}{12}[/tex]

[tex]\frac{4}{1} =\frac{x}{12}[/tex]

By cross multiplying we get:

[tex]48=x[/tex]

[tex]x=48\ inches.[/tex]

Now, again:

[tex]\frac{\frac{1}{4}}{1} =\frac{y}{16}[/tex]

[tex]\frac{4}{1} =\frac{y}{16}[/tex]

By cross multiplying we get:

[tex]64=y[/tex]

[tex]y=64\ inches.[/tex]

Therefore, on the blueprint the dimensions are 48 inches by 64 inches.

After 4 weeks, Macy and Robby will have same amount in their accounts.

Step-by-step explanation:

Given,

Amount saved by Macy each week = $12.50

Let,

x be the number of weeks.

M(x) = 12.50x

Amount saved by Robby each week = $7.50

Amount Robby already have = $20

R(x) = 7.50x + 20

For same amount;

M(x) = R(x)

[tex]12.50x=7.50x+20\\12.50x-7.50x=20\\5x=20[/tex]

Dividing both sides by 5

After 4weeks, Macy and Robby will have the same amount in their bank accounts.

To determine after how many weeks Macy and Robby will have the same amount in their bank accounts, we can set up an equation based on their weekly savings and initial amounts.

Let M(t) represent Macy's savings after  t weeks, and R(t) represent Robby's savings after t weeks.

Macy's savings can be expressed as:

M(t) = 12.50t

Robby's saving can be expressed as:

R(t) = 20 + 7.50t

We want to find the number of weeks t such that  M(t) = R(t)

Setting up the equation:

12.50t = 20 + 7.50t

To solve for t, first subtract  7.50t from both sides:

12.50t - 7.50t = 20

5t = 20

Next, divide both sides by 5 to solve for t

[tex]\[ t = \frac{20}{5} \][/tex]

t = 4

Therefore, after 4weeks, Macy and Robby will have the same amount in their bank accounts.
