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$, Cords cost 24$

How do you solve 3x+4y=12 and 2x=y-6

Answers

3x +4y =12

2x = y-6 Rewrite this as y = 2x+6

now replace that for y in the first equation

3x + 4(2x+6) = 12

now do all the calculations:

3x + 8x +24 =12

11x + 24 = 12

11x = -12

x = -12/11 = -1 1/11

now substitute -12/11 for x in the 2nd equation and solve

y = 2x+6

y = 2(-1 1/11) +6

y = 42/11 = 3 9/11

How many kilometers can the prius travel on 16 liters of gasoline?

Answers

Prius can travel up to 4.23 × x kilometers on 16 liters of gasoline.

It is given that Prius runs on gasoline.

We have to find out that how many kilometers it can run if amount of gasoline is 16 liters.

What will be the value of 16 times of a number x ?

The value will be ; 16 × x .

No. of kilometers Prius travels depends on what is the model of Prius . Also quality of roads makes a difference.

∵ 1 liter = 0.264172 gallons

⇒ 16 liters = 16 × 0.264172 = 4.23 gallons

Let's say a Prius travels x kilometers per gallon.

So ; on 16 liters of gasoline , Prius will travel ;

x × 4.23 = 4.23 × x kilometers

Thus , Prius can travel up to 4.23 × x kilometers on 16 liters of gasoline.

an angle measures 12 degrees less than 3 times its supplement

Answers

Given that the angle measures 12 degrees less than 3 times the supplement, the size of the angle will be:
suppose the size of the supplement is x;
the size of the angle supplementary to x will be:
3x-12
Given that the sum of supplementary angles is 180, thus;
x+(3x-12)=180
solving for x we get:
4x-12=180
4x=180+12
4x=192
x=192/4
x=48
the size of the supplementary angles will be:
48*3-12

D) A number line with a closed circle on 2, an open circle on 6, and shading in between

Answers

To do this, you first have to solve the first inequality for x: 2x+5>9, 2x>4 and x>2. Now solve the next one for x as well: 5x <=30, x<=6. Now work on putting them onto a number line together. Since there is not an "equal to" with that greater than, the circle is open above the 2. The next one has an "equal to" with it so that's a closed circle above the 6. This is a conjunction, meaning the solution will show what is shared between the 2 inequalities, so you have an open circle above the 2 and shading to the right til you get to the closed circle above the 6 (which is technically shaded to the left down to the open circle at 2). So your choice is B.

In a circle with an 8-inch radius, a central angle has a measure of 60°. How long is the segment joining the endpoints of the arc cut off by the angle?

Answers

calculate circumference first:

C = 2πr
C = 2(3.14159)(8 inches)
C = 50.265 inches

then 60/360 = 1/6 of the circle

50.265 inches / 6
= 8.378 inches (Round answer as needed)

Answer:

The length of segment joining the endpoints of the arc is [tex]8\ in[/tex]

Step-by-step explanation:

we know that

In the triangle ABC

see the attached figure to better understand the problem

[tex]AC=BC[/tex] -----> is the radius of the circle

[tex]m<CAB=m<CBA[/tex]

[tex]m<ACB=60\°[/tex] ----> given problem (central angle)

Initially the triangle ABC is an isosceles triangle

Remember that

the sum of the internal angles of triangle must be equal to [tex]180\°[/tex]

For this particular case, the isosceles triangle ABC becomes an equilateral triangle, as the three angles are equal to [tex]60\°[/tex]

The equilateral triangle has three equal sides and tree equal angles

[tex]AC=BC=AB[/tex]

Hence

The length of segment joining the endpoints of the arc is [tex]8\ in[/tex]

A sketch of the normal distribution is shown in the figure below.
The mean is μ, and the curve is symmetric about the mean.
The total area under the curve is 1.

The standard deviation is σ.

The interval (μ-2σ, μ+2σ) contains approximately 95% of the total area.

Answer: 95%

A line with a slope of 3 passes through the point (2,5) what is the equation of this line?

Answers

y=3x-4 because the form of a line's equation is y=mx+b where m is the slope or three in this case and b is the value of y in the y intercept and in this case it is -4 so you get y=3x+(-4) or y=3x-4.

Slope of the line equals 3 at the points (2,5) so m=0
The equation is a horizontal line, therefore the slope is 0.

A surveyor measures the angle of elevation to a point on a mountain to be 18 degrees the point on the mountain is horizontally 4 miles away from the surveyor the vertical change in elevation from the point where the surveyor is standing to the point on the mountain is___ miles?

Answers

This is right triangle trig and you are looking for the height of the triangle. The reference angle is 18 degrees, the side adjacent to that angle is 4 and you are looking for the side opposite the reference angle. The trig identity that helps us find that missing side is tangent:
[tex]tan(18)= \frac{x}{4} [/tex]
and 4 tan(18) = x.
x = 1.3 miles

Answer:

1.3 miles

Step-by-step explanation:

Solution:-

- The surveyor stands at a platform that is B = 4 miles and at an elevation of θ = 18 ° away from the point on the mountain.

- We can construct a right triangle from surveyor to the point of observation. To determine the change in height/elevation (H) we will apply the trigonometric relation as follows:

tan ( θ ) = H / B

- Solve for the elevation (H):

H = B*tan ( θ )

H = 4*tan ( 18 )

H = 1.3 miles

- The change in elevation from surveyor to point of observation is H = 1.3 miles.

Given tan A = .78 find angle A in degrees. Round your answer to the nearest hundredth.

Answers

Tangent is one of the simplest trigonometric functions which relates the sides of the triangle. This function is the ratio between the measure of the side opposite to the angle and the side adjacent to it. This can be calculated through the reverse equation of,
tan⁻¹(0.78) = A
The value of A in the equation to the nearest hundredth is 37.95°.

Answer:

[tex]A\approx 37.95^{\circ}[/tex]

Step-by-step explanation:

We have been given that [tex]\text{tan}(A)=0.78[/tex]. We are asked to find measure of angle A in degrees.

We will inverse tangent to find measure of angle A as:

[tex]A=\text{tan}^{-1}(0.78)[/tex]

[tex]A=37.954230875133^{\circ}[/tex]

Upon rounding our answer to nearest hundredth, we will get:

[tex]A\approx 37.95^{\circ}[/tex]

Therefore, the measure of angle A is approximately 37.95 degrees.

What is the range of this function?

Answers

The answer is C. Just plug in the maximum and minimum domain values (because the function is linear, you don't have to worry about more complicated things happening in the middle) and be careful with the signs.

Answer:

c) -16 ≤ x < 5

Step-by-step explanation:

The given function is f(x) = -3x + 2 and domain is -1 < x ≤ 6

The maximum value of the domain is 6 and the minimum value of the domain is -1.

To find the range, plugin the maximum and minimum value of the domain.

Plug in x = 6 in the given function, we get

f(6) = -3(6) + 2 = -18 +2 = -16

f(-1) = -3(-1) + 2 = 3 + 2 = 5

So the range is -16 ≤ x < 5
