how close are a meter and a yard? convert 1 meter into yards by using the fact
that there are 100 centimeters in a meter, 2.53 centimeters in a inch, 12 inches in a foot, and 3 feet in a yard.

Answers

Answer 1
1 meter= 100cm

2.53cm=1 inch

12 inches= 1 foot

3 feet= 1 yard

2.53*12*3=91.08

1 yard=91.08cm
1 meter=100cm

1 meter is 8.92cm longer than 1 yard

A pair of jeans costs 75% as much as a pair of corduroy pants. what is the cost of each if the total cost for the jeans and cords is $42?
I know the answer is Jeans: $18 and Cords: $24 but how do I write that in an equation to solve??
thank you!!!

Answers

Let the pair of jeans cost x dollars and the pair of corduroy cost y dollars.

"A pair of jeans costs 75% as much as a pair of corduroy pants."

this means [tex] x=\frac{75}{100}*y [/tex], simplifying by 25:

[tex]x= \frac{3}{4} y[/tex]           (equation 1)


"the total cost for the jeans and cords is $42?"

x+y=42    (equation 2)

substitute x form equation 1, in equation 2

x+y=42 

[tex] \frac{3}{4} y+y=42[/tex]

[tex] \frac{3}{4} y+ \frac{4}{4} y=42[/tex]

[tex]7y=4*42 [/tex]

y=4*6=24

substitute y=24 in either of equations 1 or 2:

x+y=42    (equation 2)
x+24=42
x=42-24=18

Answer: Jeans cost 18$, Cords cost 24$

What is the taxi distance between A(2, 5) and B(7, 9)?

Answers

If by "taxi distance" you mean travelling along the sides of the right triangle created by the two points.

t=|x2-x1|+|y2-y1|

t=5+4

t=9 units

If you mean the actual distance between the two points then:

d^2=(x2-x1)^2+(y2-y1)^2

d^2=(7-2)^2+(9-5)^2

d^2=25+16

d^2=41

d=√41 units

d≈6.4 units (to nearest tenth of a unit)

Pyramid surface area (total): Lateral surface area + Base area

Lateral surface area = [tex] \frac{2p*a}{2} [/tex] where p is the base perimeter and a the apothem.

The base is a sqaure so, find the area of the square.

Base Area = 16*16 = 256 in²

Calculate the perimeter = 16*4 = 64 in

LSA = (64*17)/2 = (64*17)/2 = 1088/2 = 544 in²

TSA = 544+256 = 800 in²

Total surface of cone: LSA + Base Area

LSA = πra

Let's find the apotheme. Apply Pitagora, again the hypothenuse is the apotheme. The legs are the radius and the height.

a = √8²+3² = √64+9 = √73 ≈ 8,5 in.

Base area (area of the circle) = πr² = 3²*π = 9π in²

LSA = 3*8,5*π = 25,5π in²

The area of the rectangle is given by the equation A = 12c² + 60c

What is the Area of a Rectangle?

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be represented as A

Now , the equation will be

Let the length of the rectangle L = ( 3c + 15 ) feet

Let the width of the rectangle W = 4c feet

Now , the area of the rectangle A = length of the rectangle L x width of the rectangle W

Substituting the values in the equation , we get

Area of Rectangle A = ( 3c + 15 ) ( 4c )

On simplifying the equation , we get

Area of Rectangle A = ( 3c ) ( 4c ) + 15 ( 4c )

Area of Rectangle A = 12c² + 60c

Therefore , the value of A is 12c² + 60c

The pressure P exerted by a force varies inversely as the area A on which the force is applied. If 16 N/ft2 of pressure is exerted by a force on an area of 3 ft2 , what is the pressure exerted by the same force on an area of 6 ft2?
A) 8 N/ft2
B) 16 N/ft2
C) 4 N/ft2
D) 32 N/ft2

Answers

The first piece of information tells you that
16 = C / 3
Solve for C
C=16×3=48
Now find P if A = 6. and C=48
P = C/6
P = 48/6
P = 8 N/ft2

Answer:

A) 8 N/ft2

Step-by-step explanation:

Pressure is the normal force per unit area, that is, it is equivalent to the force acting on the surface unit, and is given by:

[tex]P=\frac{F}{A}[/tex]

Where:

[tex]P=Pressure\\F=Normal\hspace{3}force\\A=Area\hspace{3} where \hspace{3}force\hspace{3} is \hspace{3}applied.[/tex]

In the first case:

[tex]P=16N/ft^2\\A=3ft^2[/tex]

Using the previous equation and solving for [tex]F[/tex] :

[tex]F=P*A=16*3=48N[/tex]

Now, for the second case, since the force is the same applied in the first case, then:

[tex]P=\frac{F}{A} =\frac{48}{6} =8N/ft^2[/tex]

Therefore the answer is:

A) 8 N/ft2

at maximum speed, an airplane travels 1680 miles against the wind in 5 hours. Flying with the wind, the plane can travel the same distance in 4 hours.

Answers

The speed of the airplane with the wind is 420 mph, and against the wind is 336 mph. The speed of the wind is 84 mph.

To find the speed of the wind, we use the following formulas:

Against the wind, the airplane travels 1680 miles in 5 hours. So, the speed against the wind is : [tex]\( S_a = 1680 \div 5 = 336 \)[/tex] mph

With the wind, the airplane travels the same distance of 1680 miles in 4 hours. So, the speed with the wind is: [tex]\( S_w = 1680 \div 4 = 420 \)[/tex]mph

Let W be the speed of the wind.

Against the wind: [tex]\( S_a = S_w - W \)[/tex]

[tex]\[ 336 = 420 - W \]\[ W = 420 - 336 = 84 \][/tex]

So, the speed of the wind is 84 mph.

A solution of phosphoric acid has a boiling point of 158 degrees Celsius. What is the boiling point of the solution in degrees Fahrenheit?

Answers

Final answer:

The boiling point of a phosphoric acid solution that is 158 degrees Celsius is 316.4 degrees Fahrenheit. This is found by using the formula F = C * 9/5 + 32.

Explanation:

To convert the boiling point of a solution from degrees Celsius to Fahrenheit, we use the formula F = C * 9/5 + 32, where F represents the temperature in Fahrenheit and C represents the temperature in Celsius.

In this case, the temperature in Celsius that you want to convert is 158 degrees. So you can substitute this value in the formula as follows:

F = 158 * 9/5 + 32

When you perform the calculation, you find that the boiling point of the phosphoric acid solution is 316.4 degrees Fahrenheit.

Joseph pays $20 for his base phone in addition to the $0.10 per text. Micki pays $10 for her phone plan plus the $0.15 per text. Write a function for Joesph's phone plan and for Micki's phone plan.

Provide the number of text messages in which the plans are the same plan.

Answers

j=20+0.1t

m=10+0.15t

They wil cost the same when m=j so we can say:

10+0.15t=20+0.1t, subtract 0.1t from both sides

10+0.05t=20  subtract 10 from both sides
 
0.05t=10  divide both sides by 0.05

t=200

So when one texts 200 times, both plans cost the same amount.
Final answer:

By using the equations Cj = 20 + 0.10x for Joseph's phone cost and Cm = 10 + 0.15x for Micki's phone cost, we find their costs would both be the same if 200 text messages were sent.

Explanation:

The question is asking us to create an equation for both Joseph's and Micki's texting plans. In mathematical terms, the cost for each plan would be represented by the equation Cost = base rate + (cost per letter)x, where x represents the number of texts.

So for Joseph, the equation would be Cj = 20 + 0.10x and for Micki the equation would be Cm = 10 + 0.15x.

To find out when both plans cost the same, we set the two equations equal to each other and solve for x.

20 + 0.10x = 10 + 0.15x  

By subtracting 0.10x from both sides and then subtracting 10 from both sides we get:  

x = 200.

This means that both plans would cost the same if both parties sent 200 texts.

Determine the number of possible triangles, abc, that can be formed given c = 85°, a = 10, and c = 13.

Answers

To get the possible triangle that be formed with a triangle whose dimensions are C=85, a=10 and c=13, we need to calculate for the values of the angles. Using sine rule:
a/sin A=c/sin C=d/sin D
thus the value of angle A will be:
10/sin A=13/sin 85
10/sin A=13.05
sin A=10/13.05
sin A=0.7663
A=arcsin 0.7663
A=50
thus the n=value of angle B will be:
B=180-(85+50)
=45
The triangle formed will be an acute triangle
General rule is a<bsinA means no triangle is possible, a=bsinA means 1 triangle is possible and a>bsinA means 2 possible triangles

Find the measure of each exterior angle of a regular polygon with 24 sides

Answers

the measure of each interior angle would be 165 degrees

The formula for finding the measure of each exterior angle of a regular polygon is similar to the formula for finding the measure of each interior angle. We take the sum of the measures of the exterior angles which is always 360 degrees and we divide this by the number of sides in the polygon which is n. So the formula for finding the measure of each exterior angle of a regular polygon is simply 360 over n. In this problem since the polygon has 24 sides, we simply plug a 24 in for n and we have 360 over 15. 360 divided by 24 is 15. Therefore, the measure of each exterior angle of a regular polygon that has 24 sides is 15 degrees.
