Answer:

f = - [tex]\frac{19}{7}[/tex]

Step-by-step explanation:

Given f varies directly with m then the equation relating them is

f = km ← k is the constant of variation

To find k use the condition that f = - 19 when m = 14, thus

- 19 = 14k ( divide both sides by 14 )

- [tex]\frac{19}{14}[/tex] = k

f = - [tex]\frac{19}{14}[/tex] m ← equation of variation

When m = 2, then

f = - [tex]\frac{19}{14}[/tex] × 2 = - [tex]\frac{19}{7}[/tex]

the measure of angle X is [tex]\( 104^\circ \).[/tex]

To calculate the measure of angle X in a kite-shaped scenic overlook, we'll follow these steps:

Write the equation representing the sum of the measures of all the angles in the kite, which is [tex]\( 360^\circ \).[/tex]

Identify the two angles that are equal in the kite, which are angles X and Z.

Write the equation representing the sum of these angles and the given angle measures.

Solve for the measure of angle X.

Now, let's perform the calculation:

Equation representing the sum of the measures of all the angles in the kite:

[tex]\[ \angle X + \angle Y + \angle Z + \angle W = 360^\circ \][/tex]

Identify the two equal angles:

  Since the kite has two pairs of adjacent sides that are equal, the angles opposite these sides will be equal. So, [tex]\( \angle X = \angle Z \).[/tex]

Write the equation representing the sum of these angles and the given angle measures:

[tex]\[ \angle X + 40^\circ + \angle X + 112^\circ = 360^\circ \][/tex]

Solve for the measure of angle X:

[tex]\[ 2\angle X + 152^\circ = 360^\circ \] \[ 2\angle X = 360^\circ - 152^\circ \] \[ 2\angle X = 208^\circ \] \[ \angle X = \frac{208^\circ}{2} \] \[ \angle X = 104^\circ \][/tex]

So, the measure of angle X is [tex]\( 104^\circ \).[/tex]

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo.

My answer:

=> Area of the large rectangle = length × width  = 7*5 = 35 square units

=> Area of the middle rectangle = length × width  = 7*4 = 28 square units

=> Area of the small rectangle = length × width  = 7*3 = 21 square units

Area of top and the bottom triangles =2* [tex]\frac{1}{2}bh[/tex]  [tex]= 4*3 =12[/tex]  

Total surface area = 35 + 28 + 21 + 12 = 96 square units

Answer:

It is 136

Step-by-step explanation:

Given:

The radius of the cone = 14 ft

The slant height of the cone = 27 ft

To find the lateral surface area and the total surface area of the given cone.

Formula

The lateral surface area of the cone is

[tex]LSA = \pi rl[/tex] and

The total surface area of the cone is

[tex]TSA = \pi r^{2} + \pi r l[/tex]

where,

r be the radius and

l be the slant height of the cone.

Now

Taking r = 14 and l = 27 we get

[tex]LSA = \pi (14)(27)[/tex] sq ft

or, [tex]LSA = 1187.5[/tex] sq ft

Again,

[tex]TSA = \pi(14^2)+\pi (14)(27)[/tex] sq ft

or,[tex]TSA = 1803.3[/tex] sq ft

Hence,

The lateral surface area of the cone is 1187.5 sq ft and the total surface area of the cone is 1803.3 sq ft. Option C.

Answer: His baseball cards can be represented as 0.8 of the entire collection

Step-by-step explanation: Castor has 40 baseball cards and 10 football cards. Therefore his total number of cards is given as 40 + 10 which is 50.

The fraction of his cards which are baseball cards only is calculated as

Baseball cards = 40/50

Baseball cards = 4/5

Converting 4/5 to a decimal (which can equally be done with a calculator) gives you 0.8

Hence, the part of his entire card collection that can be represented by baseball cards is 0.8

Final answer:

To find the number of rides that you went on at the fair given the total cost, $26, and the cost per ride, $3, you can use the equation $26 = $5 + $3r. Solving for r, you find that you went on 7 rides.

Explanation:

To write an equation that shows the number of rides, r, that you went on, we need to consider the total cost you spent and the cost per ride.

The cost to enter the fair is $5, and for every ride you go on, it costs $3. So, the equation would be:

Total Cost = Cost to Enter + Cost per Ride x Number of Rides

In this case, you spent a total of $26. Plugging in the values, we get:

$26 = $5 + $3r

Now, we can solve for r by isolating the variable:

$26 - $5 = $3r

$21 = $3r

To find the number of rides, divide both sides by $3:

r = $21/$3

r = 7

Therefore, you went on 7 rides at the fair.

Answer:

120 pens and 200 pencils

Step-by-step explanation:

Let the number of pencils bought be x while pens will be y.

Cost

Considering that a pen costs $1 then for y pens, the cost will be y*$1=$y

The pencils cost $0.5 then for x pencils the cost will be $0.5*x=$0.5x

Total cost is $220 hence expressed as

0.5x+y=220

Quantity

Since the number of pencils, x were more than number of pens, y by 80 pieces then

x=80+y

Since we initially had the equation 0.5x+y=220 then we substitute x with 80+y hence

0.5(80+y)+y=220

40+0.5y+y=220

1.5y+40=220

1.5y=220-40=180

y=180/1.5=120

Since x=y+80 and y is found to be 120 then

x=120+80=200

Solution of the equation is x = -18

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given equation,

(2/3)x = -12

Multiplying with 3 on both sides,

3×(2/3)x = -12×3

2x = -36

Dividing by 2 on both sides

2x/2 = -36/2

x = -18

Hence, x = -18 is the solution of the equation.

The third answer

Step-by-step explanation:

(side note: You probably need to use a calculator that can calculate pi)

The formula to find the area of a circle is pi r squared.

In this case, pi times r squared is 19.63495....... continued

This is probably going to be rounded

so... 19.63

For all of the circles, this is multiplied by 4.

This is 78.52

The area of the square is 100 cm since 10 times 10 is 100

You take 100 cm and then subtract it by 78.54

A perfect square is a number formed by multiplying two equal integers by themselves. The number that is a perfect square is 121.

A perfect square is a number formed by multiplying two equal integers by themselves. The number 9 is a perfect square, for example, since it can be written as a product of two equal integers: 3 x 3 = 9

A number is a perfect square if another number that when divided the number the quotient is the number which divided another. Therefore, the number that is a perfect square is 121.

121 ÷ 11 = 11

Hence, the number that is a perfect square is 121.

Step-by-step explanation:

Given:

Given that the polygon has 4 sides with its exterior angles.

The exterior angles are 140°, 34°, 56° and x°

We need to determine the value of x.

Value of x:

We know that, the exterior angles of a polygon add up to 360°

Thus, we have;

[tex]140^{\circ}+34^{\circ}+56^{\circ}+x=360^{\circ}[/tex]

Adding the terms, we have;

[tex]230^{\circ}+x=360^{\circ}[/tex]

Subtracting both sides of the equation by 230, we get;

[tex]x=130^{\circ}[/tex]

Thus, the value of x is 130°

Final answer:

The value of the unknown exterior angle x in the quadrilateral is 130 degrees, calculated by subtracting the sum of the given exterior angles from the total sum of 360 degrees.

Explanation:

The student is asking about finding the value of an unknown exterior angle (x) in a quadrilateral. In geometry, the sum of the exterior angles of any polygon always equals 360 degrees. Given that three of the exterior angles are provided as 140 degrees, 34 degrees, and 56 degrees, we can find the value of the unknown exterior angle x degrees by subtracting the sum of these provided angles from 360 degrees.

First, we add the given angles:

140 degrees + 34 degrees + 56 degrees = 230 degrees

Next, we subtract the total from 360 degrees to get the value of x:

360 degrees - 230 degrees = 130 degrees

Therefore, the value of x, the unknown exterior angle of the quadrilateral, is 130 degrees.

Option A) 2/3 πx³ is the expression that represents the volume of cone in cubic units.

Step-by-step explanation:

The general formula for the volume of the cone is given by,

⇒ 1/3 πx²h

where,

It is given that,

Height of the cone is twice the radius of its base.

Therefore, the volume of the cone is represented as

⇒ Substitute h=2x in the volume of the cone volume.

⇒ 1/3 πx²(2x)

⇒ 2/3 πx³ cubic units.

Hence, option A) 2/3 πx³ is the expression that represents the volume of cone in cubic units.

Answer: 24 nickels

Step-by-step explanation:

1. n= nickels

q=quarters

2. n+q=39

.05n+.25q=4.95

3. n=39-q (Replace n with what n is equal to in the other equation) .05(39-q)+.25q=4.95

4. Solve for q: (.05x39)+(.05x-q)+.25q=4.95

5. 1.95-.05q+.25q=4.95 (Combine like terms)

6. 1.95+(-.05q+.25q)=4.95

7. 1.95+0.2q=4.95

8. Move 1.95 to the other side of equal sign by subtracting it from both sides. 0.2q=3

3/0.2= 15... so quarters=15

So if you look back at the other equation it says n+q=39. So, 39-15=24. There is 24 nickels.
