Here’s a graph picture...

Answer:

∠EFA

Step-by-step explanation:

Linear pair : A linear pair is a pair of adjacent angles formed when two lines intersect and the sum of these angles is 180°

Vertical angles: The opposite angles formed by the two intersecting lines are called vertical angles.

Option 1) ∠BFC

Line BE and CF intersect at point F

So, the two adjacent angles formed when two lines intersect are ∠BFC and ∠EFC.

These are linear pair.

So,  ∠BFC is a part of linear pair.

Now by the definition of vertical angles , ∠BFC has no vertical pair.

So, ∠BFC is not a part of vertical pair.

Option 2) ∠CFG

According to the definition of linear pair ∠CFG is not a part of linear pair.

According to the definition of vertical pair ∠CFG is not a part of vertical pair.

Option 3) ∠GFD

According to the definition of linear pair ∠GFD has a linear pair ∠AFG

Thus ∠GFD is a part of linear pair

According to the definition of vertical pair ∠GFD is not a part of vertical pair.

Option 4) ∠EFA

According to the definition of linear pair ∠EFA has a linear pair ∠EFD

Thus ∠EFA is a part of linear pair

According to the definition of vertical pair ∠EFA has a ∠BFD vertical pair.

Thus ∠EFA is a part of vertical pair.

Hence ∠EFA is part of a linear pair and part of a vertical pair.

Answer:

D) EFA

Step-by-step explanation:

Let's see the definition of linear pair and vertical angles.

A linear pair of angles are the adjacent angles, when the angles add upto 180°.

Vertical angles are the  opposite angles when the two lines are intersecting. The vertical angles are equal in measure.

In the given figure there are only two lines, they are AD and BE. Othere are just rays.

By look at the figure, ∠EFA is a linear pair to∠EFD and as well as vertical angle to ∠DFB.

Therefore, the answer is D) EFA

Answer: 39$

Step-by-step explanation: calls=x x=30 30*.05= 1.50 40.50-1.50= 39$

Answer:38.55

Step-by-step explanation:

because you would make x=to 30 for the time and that would make the problem

40.05-0.05*30

0.05*30=1.5 so

40.05-1.5=38.55

The answer is y = 3x - 2

Y=3x-2

The formula y=mx+b is the slope intercept formula. You would enter the information of the problem into the equation.

You would place the slope in the place of m and the y intercept in the place of b.

Since it is a negative slope it would be -2 instead of +2 if it was positive.

Answer:

295

Step-by-step explanation:

.3 x 295 = 88.5

295 - 88.5 = 206.5

For this case we must find the solutions of the following quadratic equation:

[tex]x ^ 2-5x-1 = 0[/tex]

We solve by means of[tex]x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}[/tex]

Where:

[tex]a = 1\\b = -5\\c = -1[/tex]

Substituting:

[tex]x = \frac {- (- 5) \pm \sqrt {(- 5) ^ 2-4 (1) (- 1)}} {2 (1)}\\x = \frac {5 \pm \sqrt {25 + 4}} {2}\\x = \frac {5\pm\sqrt {29}} {2}[/tex]

Finally, the roots are:

[tex]x_ {1} = \frac {5+ \sqrt {29}} {2}\\x_ {2} = \frac {5- \sqrt {29}} {2}[/tex]

Answer:

[tex]x_ {1} = \frac {5+ \sqrt {29}} {2}\\x_ {2} = \frac {5- \sqrt {29}} {2}[/tex]

Answer:

900 miles

Step-by-step explanation:

Well, 200 miles is 1 inch. 100 miles is 1/2 an inch.

Answer:

900

Step-by-step explanation:

Given: 1/4 in. = 50 miles

Find the amount of miles per inch. Multiply 4 to both sides of the equation.

(1/4 in.) x (4) = (50 miles) x (4)

4/4 in. = 200 miles

1 in. = 200 miles

Now, find the amount of miles for 4 1/2 in. Multiply 4 1/2 to both sides.

Note that 4 1/2 = 4.5

(1 in.)(4.5) = (200 miles) x (4.5)

4.5 = 200 x 4.5

4.5 = 900

900 miles is your answer.

Answer:

£9.6

Step-by-step explanation:

x = the original price of a CD

£x = 100% of the original price

The price of a CD was decreased by 20% to £7.68.

This means:

£7.68 = 100% - 20%

£7.68 = 80% of the original price

From this, we will find 1% of the original price.

£7.68 ÷ 80 = 1%

£0.096 = 1%

Since the original price ( x ) = 100% of the original price, we will find 100% of the original price.

£0.096 × 100 = 100%

£9.6 = 100%

Therefore, the original price of a CD = £9.6

The price before the decrease was approximately £9.60.

To find the price before the decrease, we need to calculate the original price before the 20% decrease. Let's call the original price 'x'. We know that after the 20% decrease, the price is £7.68.

So, if we take 20% of 'x' and subtract it from 'x', we should get £7.68. Mathematically, this can be expressed as:

x - 0.20x = 7.68

Simplifying the equation, we have:

0.80x = 7.68

Dividing both sides of the equation by 0.80, we find that 'x' is approximately 9.60. Therefore, the price before the decrease was approximately £9.60.

Answer:

x = - 2, x = 12

Step-by-step explanation:

Given

x² - 10 x  = 24 ( subtract 24 from both sides )

x² - 10x - 24 = 0 ← in standard form

To factorise the quadratic

Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 10)

The factors are - 12 and + 2, since

- 12 × 2 = - 24 and - 12 + 2 = - 10, thus

(x - 12)(x + 2) = 0

Equate each factor to zero and solve for x

x - 12 = 0 ⇒ x = 12

x + 2 = 0 ⇒ x = - 2

The solution of this quadratic equation to x² – 10 x = 24 is  x = - 2 & x = 12

A quadratic is a sort of problem that deals with a variable accelerated by using an operation called squaring. This language derives from the area of a rectangular being its facet period expanded with the aid of itself. The phrase "quadratic" comes from quadrant, the Latin word for square.

x² – 10 x = 24

⇒ x² +2X -12X -24 = 0

⇒ x (x - 2) -12(x - 2) =0

⇒ x = 12 OR ( x = -2)

The expression (4y^6)^3 - (10z^2)^3 is equivalent to 64y^18 - 1000z^6.

Factor out common powers:

64y^18 = (2^6)(y^3)^6

1000z^6 = (10^3)(z^2)^3

Rewrite the expression with factored terms:

64y^18 - 1000z^6 = (2^6)(y^3)^6 - (10^3)(z^2)^3

Apply power of a power rule:

(a^m)^n = a^(mn)

(2^6)(y^3)^6 = 2^(66) * y^(36) = 2^36 * y^18

(10^3)(z^2)^3 = 10^(33) * z^(2*3) = 10^9 * z^6

Substitute back the simplified terms:

2^36 * y^18 - 10^9 * z^6 = (4y^6)^3 - (10z^2)^3

Therefore, (4y^6)^3 - (10z^2)^3 is the equivalent expression to 64y^18 - 1000z^6. Both expressions involve the difference of cubes of binomials, with one focusing on powers of 4y^6 and the other emphasizing powers of 10z^2.

Step-by-step explanation:

$22.75

Start by finding the cost of each topping. Subtract $17.50 minus $14.00 to find that adding 2 toppings costs $3.50. Now, divide $3.50 by 2 to find that the cost for adding only one topping is $1.75.

Then, multiply $1.75 by 5 to find how much it costs to add 5 toppings. You get $8.75.

Finally, add the cost of 5 toppings to the cost of a large pizza with no toppings. $14.00 plus $8.75 equals $22.75, so a large pizza with 5 toppings costs $22.75.

Answer: $22.75

Step-by-step explanation:

Given : The cost in dollars, y, of a large pizza with x toppings from Pat’s Pizzeria can be modeled by a linear function.

A linear function is given by :-

[tex]y=mx+c[/tex]                            (1)

, where m is slope (rate of change of y w.r.t x) and c is the y-intercept.

A large pizza with no toppings costs $14.00.

i.e. for x=0 , y= 14

Put theses values in (1) , we get

[tex]14=m(0)+c\\\Rightarrow\ c=14[/tex]   (2)

A large pizza with 2 toppings costs $17.50.

i.e. for x=2 , y= 17.50

Put theses values in (1) , we get

[tex]17.50=m(2)+c[/tex]      

Put value of c from (2)

[tex]17.50=2m+14\\\\[/tex]      

Subtract 14 from both sides , we get

[tex]3.50=2m[/tex]

Divide both sides by 2 , we get

[tex]1.75=m[/tex]

Put m= 1.75 and c= 14 in (1) , the linear function representing cost of large pizza becomes [tex]y=1.75x+14[/tex]

At x= 5

[tex]y=1.75(5)+14=8.75+14=22.75[/tex]

Thus , the cost of a pizza with 5 toppings= $22.75

Answer:

The diagonal is 39.54 in

Step-by-step explanation:

First we use the Pythagorean theorem to calculate the length of the diagonal of the base.

If the base measures 13 inches by 35 inches then the diagonal is:

[tex]c = \sqrt{13^2 +35^2}\\\\c= 37.34\ in[/tex]

Now we use the Pythagorean theorem again to find the diagonal of the cube.

If the height of the box is 13 inches and the diagonal of the base is 37.34 inches then the diagonal of the cube will be

[tex]z = \sqrt{37.34^2 +13^2}\\\\z= 39.54\ in[/tex]

The baton will fit in the box if it is placed in the direction of the diagonal of the cube, since:

39.54\ in > 38 inches

Using the 3D Pythagorean theorem, the diagonal of the box is calculated to be approximately 39.53 inches, which means that Kylie's 38-inch baton will fit inside the box diagonally.

Kylie needs to check if her 38-inch long baton will fit diagonally in a box with dimensions of 13 inches by 35 inches by 13 inches. To determine whether the baton will fit, she needs to find the length of the longest diagonal of the box. This is solved by using the 3D Pythagorean theorem, which is an extension of the traditional Pythagorean theorem applied to three dimensions.

To find the length of the diagonal (d), we use the formula:

d = √(l² + w² + h²)

Where l is the length, w is the width, and h is the height of the box. Substituting the given values:

d = √(13² + 35² + 13²)

d = √(169 + 1225 + 169)

d = √1563

d ≈ 39.53 inches

The calculated diagonal length of approximately 39.53 inches indicates that Kylie's baton, which measures 38 inches, will indeed fit inside the box diagonally.

Answer:  2 years 1 month

Step-by-step explanation:

2 years 1 month at $100 a month = $2,500

$720 x 2 years = $1,440

$720 / 12 months = $60

$1,440 + $60 = $1,500

$4,000 - $1,500 = $2,500

The two investment funds will have the same amount of money after 25 months. This conclusion is reached by setting up and solving an equation where the monthly growth of the first fund, $100x, equals the monthly decrease of the second fund, $4000 - $60x.

Let's denote the time in months that it takes for both investment funds to have the same amount of money as x. The equation that represents the first fund's growth is 100x, as it grows at $100 per month. The equation for the second fund is 4000 - 60x, as it decreases by $720 per year, or $60 per month.

We can set these two equations equal to each other to solve for x: 100x = 4000 - 60x. Solving this equation involves adding 60x to both sides to yield 160x = 4000, and then dividing by 160 to get x = 25. Therefore, after 25 months, both funds will have the same amount of money.
