Step-by-step explanation:

2 yards = 6 feet

6 feet = 72 inches

3 yard = 9 feet

9 feet = 108 inches

4 yards = 12 feet

12 feet = 144 inches

5 yards = 15 feet

15 feet = 180 inches

If the length of of a square increases from 3 inches to 7inches,the perimeter will increase from 12 inches to 28 inches. The perimeter will increase by 16inches

Square is a regular quadrilateral, which has all the four sides of equal length and all four angles are also equal. The angles of the square are at right-angle or equal to 90-degrees. Also, the diagonals of the square are equal and bisect each other at 90 degrees.

The perimeter of a square is determined by adding all the sides together.

Therefore the perimeter of square = 4l

when the length is 3 inches, the perimeter = 4×3 = 12inches

when the length is 7inches , the = 4× 7 = 28inches

Therefore the perimeter increased from 12inches to 28inches. It increases by 16 inches

Answer:

She has 27 quarters

Step-by-step explanation:

Let:

x = Number of nickels

y = Number of quarters

US$0.05 = 5 cents = monetary value of a nickel

US$0.25 = 25 cents = monetary value of a quarter

                      x + y = 68

                     x = 68 - y  ---- --------  (equation i)

                0.05x + 0.25y = 8.80----- (equation ii)

These two are linear simultaneous equations, which can be solved either by substitution, elimination or graphical method.

Substitution method:

Substitute (equation i) into (equation ii) to solve for y:

0.05(68 - y) + 0.25y = 8.80

Expand the brackets by applying the Distributive Law and then bring all the like terms together. y needs to be isolated and made the subject of the equation:

= 3.4 - 0.05y + 0.25y = 8.80

= 0.25y - 0.05y = 8.80 - 3.40

= 0.20y = 5.40

= y = [tex]\frac{5.40}{0.20}[/tex]

∴ y = number of quarters = 27

The angle measures for this problem are given as follows:

Angle 3 has the same measure as angle 1, thus:

m < 3 = m < 1 = 68º.

Angles 1, 2 and 3 form a ray, adding to 180º, meaning that the measure of angle 2 is obtained as follows:

m < 2 + 2 x 68 = 180

m < 2 = 44º.

The sum of the internal angles of a triangle is of 180º, hence the measure of angle 5 is given as follows:

44 + m < 5  + 35 = 180

m < 5 = 180 - 79

m < 5 = 101º.

Each exterior angle is supplementary with it's interior angle, having their measures adding to 180º, hence the measures of angles 4 and 7 are obtained as follows:

Step-by-step explanation:

Both teams can complete the search in a time period of 4 hours.

Distance is a measurement of how far apart two points or objects are from one another. Time is a unit used to describe how long it takes for an object to travel between two points. Speed is a unit used to describe how quickly or slowly an item or a point moves.  

Here we have

Two search-and-rescue teams leave base camp at the same time,
looking for a lost child.

The first team, on horseback, heads north at 3 mph,  

The second team, on foot, heads south at 2.5 mph.

Let both teams complete searching in 'x' mins

The distance traveled by 1st team in 'x' mins = 3 × x  

= 3x  m

The distance traveled by 2nd team in 'x' mins = 2.5 × x

Chen here tried to classify shapes from least specific to most specific. But the order is incorrect. The correct order is Quadrilateral, parallelogram, rhombus, square.

A quadrilateral is a shape having four sides. Any shapes with a four side is a quadrilateral. It can be an undetermined shape or a parallelogram, rectangle, rhombus or square. Parallelogram have four sides. Opposite sides are parallel and congruent. A rhombus, rectangle, square can all be considered a parallelogram.

A rhombus have four congruent sides and opposite sides are parallel. All squares are rhombi, but not all rhombi are squares. Square is the most specific shape. All sides of the square must be equal and all angles must be 90°.

We can say all squares are rhombus, all rhombi are parallelograms, all parallelograms are quadrilaterals.

Answer: 3 jackets and 5 sweaters

Step-by-step explanation:

j = jeans      s = sweaters

175 = 25j + 20s  ---- this will calculate the cost

8 = j + s ----- how much she bought

j = 8 - s; plug this into the cost

175 = 25(8-s) + 20s

175 = 200 - 25 + 20s; subtract 200 on both sides

-25 = -5s divide -5 to isolate the s

s = 5 Shelly bought 5 sweaters

now plug s = 5 in how much she bought

8 = j + 5

j = 3 Shelly bought 3 jackets

We are this cut into 32, that is, 32 centimeters long is cut into 2 pieces. So let's do that. First, we're going to cut this ore into 2 pieces, didn't say down the middle, so we're going to say this has a piece length of x, which means this piece is going to have a length of 32 minus x. So what we're going to do is we're going to take each 1 of these pieces. Let me get them in different colors here and we're going to make a square out of each 1 of those pieces so for the blue piece, we're going to have this square and for the green piece we're going to have a square. That'S a little bit longer and we want to know the function for the area. Well, let's see how for the area, then we're going to need to take sides squared, so we need to figure out what the sides are for each 1 of these squares. Well, since we're wrapping it around we're going to separate this into 4 separate pieces, so that's going to be x over 4 would be a length of that side. We'Re going to do the same thing here and get 32 minus x over 4. Wrapping that green around to get that particular length. So that means the area of this blue square is going to be x over 4 squared. The area of this green square is gonna, be 32 minus x over 4 squared. So our total area is going to be x over 4 squared plus 32 minus x over 4 squared. They now want us to minimize this. We have to simplify this. That'S gonna, be x, squared over 16 plus and that's going to be over 16 was 32 times. 32 poiokay 1024 minus 64 x plus x, squared all that's over 16 point, so it's going to end up being 2 x, squared minus 64 x plus 1024. Over 16 point. I want to make this a pretty polly. So im gonna make this x squared over 8 minus 4 x and then that's going to be 64 point. Well, we want to minimize the area i see here. We have a quadratic with a leading coefficient that is positive, so means we're going to have a parabola that opens down, so our vertex is going to be our minimum. We'Re going to look at that and say that our vertex is going to be negative b over 2 a when i look at this particular equation. I see that we have a coefficient of 1 eighth on my square term. That'S going to be my value of a and we have a negative 4 on our ex term. That'S going to be our value of b! So i'm going to substitute that here and get negative negative 4 over 2 times 18 point. So that's going to be 4 over 1. Fourth, which is going to be 116 point, so x is going to have a value of 116 point. What is going to be that area for we now need to take that 1 sixteenth and put it in place of x. So i'm going to do that in a of x. I winna get a of 116 point, so thats gonna be 1 eighth times 1. Sixteenth squared minus 4 times 1, sixteenth minus 64 point. So let's see what that's going to be. This should have been 16, not 116 point. So i'm going to go back and redo this with 16 point where's, my racer! Sorry about that gem! Reciprocal is mixed up. So that's gonna be 16 point. So let's see what that's going to be: that's going to be 1 over 8 times, 16 times 16 point. So that's going to be 32 point and then we're goin to have minus 64 minus 64 point something all right. So that should ave been a plus so were maximum area is going to be mum area.

Hence, the equation of the line is y=5.

Answer:

a = 3

Step-by-step explanation:

Since the line passes through the origin, we can find its equation using the two given points.

The slope of the line is:

m = (3 - 9) / (40 - a - 2a - 50) = -6 / (10 - 3a)

Using the point (2a+50, 9), we can find the y-intercept (b) of the line:

9 = m(2a+50) + b

b = 9 - m(2a+50)

b = 9 + (6/(3a-10))(2a+50)

So the equation of the line is:

y = (-6 / (3a-10))x + (9 + (6/(3a-10))(2a+50))

Since the line passes through the origin, the y-intercept (b) must be zero. Therefore:

0 = 9 + (6/(3a-10))(2a+50)

6(2a+50) = -9(3a-10)

12a + 300 = -27a + 90

a = 210/39

The vertex of the function is (x, y) = (-4, -14), so the vertex is at (x = -4, y = -14).

The equation can be written in vertex form by completing the square:

M(x) = x^2 + 8x - 10 = (x^2 + 8x) - 10 + (8/2)^2

= (x + 4)^2 - 14

The vertex of the function is (x, y) = (-4, -14), so the vertex is at (x = -4, y = -14).

To find the vertex of a quadratic function, you can use the formula:

Vertex = (x, y) = ( -b / 2a, f( -b / 2a) )

Where "a", "b", and "c" are the coefficients of the quadratic function in the standard form:

f(x) = ax^2 + bx + c

Note that the vertex of a quadratic function is either a minimum or maximum point, depending on the sign of the coefficient "a". If "a" is positive, the vertex represents the minimum point of the parabola. If "a" is negative, the vertex represents the maximum point of the parabola.

Step 1: Calculate the normal usage for the coming month. Since normal usage is one case of 12 cans per week and the coming month is expected to be very busy, requiring 50 percent more tomato juice than normal, the normal usage for the coming month can be calculated by multiplying 12 cans per week by 4 weeks, then multiplying that number by 1.5, which gives us a total of 72 cans.

Step 2: Calculate the desired ending inventory for the coming month. The desired ending inventory for the coming month is 18 cans.

Step 3: Calculate the quantity to order. To calculate the quantity to order, we need to subtract the quantity on hand (6 cans) and the desired ending inventory (18 cans) from the normal usage (72 cans). This gives us a total of 48 cans to order.

Step 4: Calculate the number of cases to order. To calculate the number of cases to order, divide the quantity to order (48 cans) by 12 cans per case, which gives us 4 cases.
