A percentage is a way to describe a part of a whole. The approximate percent decrease in the price is 21.87%, thus, the correct option is B.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given the reduction in the price is $7, while the original cost is $32. Therefore, the approximate percent decrease in the price is,

Percentage decrease = 7/32  × 100%

                                     = 21.87%

Hence, the approximate percent decrease in the price is 21.87%, thus, the correct option is B.

The correct question is:

Helen got a $7 reduction in the price of a pair of jeans that are normally $32. What is the approximate percent decrease in the price?

The percent decrease is approximately 15%.

The percent decrease is approximately 21%.

The percent decrease is approximately 43%.

Step-by-step explanation:

x is the number.

(x + 5) - 2x : the sum of the number and 5 decreased by twice the number.

or simplified without the brackets

x + 5 - 2x = 5 - x

The approximate value of b in the triangle is D. 9.4 units.

From the information, it should be noted that WZY and XWY are similar triangle.

The corresponding ratio will be:

XW/WZ = XY/WY = WY/ZY

The calculation of WZ using Pythagoras will be 7.81.

This will be substituted into the ratio.

b/7.81 = 6/5

The correct statements are:

There are four ways to choose the committee.

There are three ways to form the committee if person D must be on it.

If persons B and C must be on the committee, there are two ways to form the committee.

It is given that:

A membership committee of three is formed from four eligible members.

1)

There are four ways to choose the committee.

This statement is true.

since we have to choose 3 members out of the 4 members so we can use the method of combination.

2)

There are three ways to form the committee if person D must be on it.

This statement is also true.

since D has to be in the committee, this means we have to choose 2 more people out of the three people to form the committee.

3)

If seven members are eligible next year, then there will be fewer combinations.

This statement is wrong.

Since we have to choose 3 members out of 7 members so the number of possible combinations will be:

i.e. there are 35 combinations possible.

4)

If persons B and C must be on the committee, there are two ways to form the committee.

if B and C have to be in the committee then we have to choose just one person out of the two people left.

Hence, the statement is true.

5)

If persons A and C must be on the committee, then there is only one way to form the committee.

If A and C have to be in the committee then as in last option we have to choose any one of the two person left.

so possible number of ways are 2.

Answer: D) 1/5

Step-by-step explanation:

Format for point-slope form:  y-y₁=m(x-x₁)

x1, y1 is a point on the line

m is the slope

So in this equation, m = 1/5

so, the slope is 1/5

hope this helps!

Answer:

A) y = –3x+8

Step-by-step explanation:

first off, a negative equation means the graph is downward sloping from left to right –> \. So with this in mind you can immediately eliminate C and D because they are upward sloping graphs. B also doesn't work because it doesn't go through (3,–1). This leaves A as the right answer

the constant number is the number on the y-axis. So, for –3x+2, +2 is the y-coordinate on the y-axis. the slope is -3x meaning down 3, right 1. –3x+8 is the only answer that is perpendicular.

Answer:

it can't be solved if we don't know the values of atleast one of the x and y.

Hope this helps.

Good luck ✅.

Answer:

Step-by-step explanation:

2x + 3y = 6

y = x/3 - 3

Since the second equation is already solved for y, we can easily use the substitution method.

Substitute y in the first equation with x/3 - 3

2x + 3(x/3 - 3) = 6

2x + x - 9 = 6

3x = 15

x = 5

Now use the second equation, and x = 5, to solve for y.

y = x/3 - 3

y = 5/3 - 3 = 5/3 - 9/3

y = -4/3

Answer: (5, -4/3)

Step-by-step explanation:  

The multiplicative rate is 9 if the table that shows an exponential function option fourth is correct.

It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x

where a is a constant and a>1

We have a table that shows an exponential function.

As we know the exponential function:

y = a(b)ˣ

Plug x = 1, y = 6

6 = ab ...1

Plug x = 2, y = 4

4 = ab²  ...2

Divide equations 1 and 2

ab²/ab  = 4/6

b = 2/3

Plug the value of b in the 1 equation.

a(2/3) = 6

a = 9

y = 9(2/3)×

The multiplicative rate = 9

Thus, the multiplicative rate is 9 if the table that shows an exponential function option fourth is correct.

Elizabeth will take 9 hours and 45 minutes to catch up with Duane using the given speed-distance-time values.

The speed-distance-time relations are:

Speed = Distance/Time, Distance = Speed*Time, and Time = Distance/Speed.

The distance traveled by Duane on the bike at 14 miles per hour for 3 hours = 14*3 miles = 42 miles.

The time that Elizabeth takes to cover 42 miles jogging at 5 miles per hour = 42/5 hours = 8.4 hours.

The distance traveled by Duane in the extra time which Elizabeth took to reach his bike (8.4 - 3 = 5.4 hours) walking at 2 miles per hour = 2*5.4 = 10.8 miles.

Now, the distance between Elizabeth and Duane is 10.8 miles, before Elizabeth starts riding the bike.

Keeping the distance constant, we calculate the relative speed to calculate the time to cover this distance.

Relative speed = Elizabeth's speed - Duane's speed {As Elizabeth is moving towards Duane, that is, covering the distance but Duane is moving away from Elizabeth, that is, increasing the distance}.

or, Relative speed = 10 - 2 = 8 miles per hour.

Time taken to cover the distance = 10.8/8 = 1.35 hours.

Therefore, the total time taken by Elizabeth to catch up with Duane = 8.4 + 1.35 hours = 9.75 hours or 9 hours and 45 minutes.

Explanation:  Given that we have the slope and a point on the graph we can use the point slope formula to find the equation of the line.

Answer:

  58.0°

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relationships between sides of a right triangle and trig functions of the acute angles.

Here, the hypotenuse of the triangle is given (17 cm), as is the side adjacent to angle x (9 cm). This suggests using the relation ...

  Cos = Adjacent/Hypotenuse

  cos(x) = (9 cm)/(17 cm) = 9/17

The angle for this cosine value is found using the inverse trig function.

  x = arccos(9/17)

  x ≈ 58.034°

Rounded to the nearest tenth, the angle is ...

  x = 58.0°

ABCD is a parallelogram (Given)

As opposite angles of a parallelogram are equal

Also

From (1) and (2)

<A is congruent to <FCE

The value of 'x' is 25.00

The given figure is a triangle

To find the value of 'x', first find the value of the other side

Using

Hypotenuse square = opposite square + adjacent square

16^2 = 10^2 + y^2

256 = 100 + y^2

Make y subject of formula

y = √ 256- 100

y = √ 156

y= 12. 49

To find 'x'

28^2 = x^2 + 12.59^2

784 = x^2 + 158. 51

x^2 = 784 - 158. 51

x^2 = 625. 49

x =√ 625. 49
