Answer:

Andre should stop at (-3 , 6.5)

Step-by-step explanation:

The change in x is from -15 to 25 which is 40 units. 40 x 3/10 = 12 which means Andre moves 12 units right starting from -15 so the x coordinate is -15+12 = -3

The change in y is from 2 to 17 which is 15 units. 15 x 3/10 = 4.5 which means Andre moves 4.5 units up starting from 2 so the y coordinate is 2+4.5 = 6.5.

Answer:

D. 37.5

Step-by-step explanation:

In order to calculate percent decrease you need to follow this formula:

((Starting value - Ending value) / Starting value) x 100

Now we plug the numbers into the formula and solve:

((8-5)/8) x 100

3/8 x 100

0.375 x 100

37.5%

Answer:The last one

Step-by-step explanation:

Answer:

i think its A .

Step-by-step explanation:

There is no perfect square factor of 30 thus it cannot be simplified thus, and option (D) will be correct.

The number system is a way to represent or express numbers.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given, √30

If we could make the perfect square factor of 30 then it will come out from the radical sign as,

√12 = √(4 × 3) = √(2² × 3) = 2√3

Therefore, the √30 cannot be simplified.

Hence "There is no perfect square factor of 30 thus it cannot be simplified".

Answer:

15^2 + 36^2 = c^2

225+1296 = c^2

sqrt(1521) = sqrt(c)

c = 39

1st Blank - 15

2nd Blank - 2

3rd Blank - 225

4th Blank - 1296

5th Blank - 1521

6th Blank  - c

7th Blank - 39

Step-by-step explanation:

Using the pythagorean theorem we know a^2+b^2=c^2 so by filling out a and b into the blanks we then know the sum of a and b squared is equal to c squared then to cancel out the exponent we use the radical then find c is equal to 39.

Answer:

1. 15^2 + 36^2=c^2

2. 225 + 1296=c^2

3. sqrt (15^2 36^2)=sqrt (c^2)

Here is an example of how to draw an isosceles trapezoid:

   _______

 /                 \

/_________\

In this trapezoid, the two parallel sides (the top and bottom sides) are of equal length, and the two non-parallel sides (the left and right sides) are also of equal length. The angles between the top and left sides and between the top and right sides are equal, as are the angles between the bottom and left sides and between the bottom and right sides.

An isosceles trapezoid is a type of trapezoid where the two non-parallel sides of the trapezoid are of equal length. This means that the trapezoid has a line of symmetry through its mid-point, which divides the trapezoid into two congruent triangles. The two parallel sides of an isosceles trapezoid are also referred to as bases, and the height of the trapezoid is the perpendicular distance between the two bases.

Because an isosceles trapezoid has two congruent triangles, the angles opposite these sides are also congruent. Therefore, an isosceles trapezoid has two pairs of congruent angles, with each pair containing one acute angle and one obtuse angle. The acute angles are located adjacent to the parallel sides, while the obtuse angles are located adjacent to the non-parallel sides.

Isosceles trapezoids have several interesting properties, including that the diagonals of an isosceles trapezoid are congruent, and that the diagonals bisect each other. Additionally, the length of each diagonal can be found using the Pythagorean theorem, and the area of an isosceles trapezoid can be determined using the formula:

Area = ((a + b) / 2) * h

Where "a" and "b" are the lengths of the two parallel sides (bases) and "h" is the height of the trapezoid.

PART B:

An isosceles trapezoid is a quadrilateral with two parallel sides (the bases) and two non-parallel sides of equal length. A parallelogram is also a quadrilateral with two pairs of parallel sides.

An isosceles trapezoid can be thought of as a special case of a parallelogram where one pair of opposite sides is shorter than the other pair. In fact, if you extend the non-parallel sides of an isosceles trapezoid until they intersect, you will get a parallelogram with the same base and height as the original trapezoid.

Conversely, if you take a parallelogram and draw a line segment parallel to one pair of opposite sides, you will get an isosceles trapezoid. This means that every isosceles trapezoid can be thought of as a parallelogram with a missing piece, and every parallelogram can be thought of as an isosceles trapezoid with extra pieces added on.

So, in summary, isosceles trapezoids and parallelograms are related in that isosceles trapezoids can be thought of as special cases of parallelograms, and parallelograms can be thought of as isosceles trapezoids with extra pieces added on.

PART C:

No, we cannot use the term "isosceles" to describe a rectangle because a rectangle, by definition, has four right angles and opposite sides that are parallel and congruent to each other. An isosceles trapezoid, on the other hand, has only one pair of parallel sides and two non-parallel sides that are congruent to each other.

The term "isosceles" is typically used to describe triangles or trapezoids where two sides are congruent to each other. In an isosceles triangle, two sides are equal in length, while in an isosceles trapezoid, two non-parallel sides are equal in length. However, in a rectangle, all four sides are equal in length, not just two.

Therefore, while we can describe a rectangle as having all sides congruent to each other, we cannot describe it as an isosceles rectangle because "isosceles" implies only two sides are congruent, which is not the case for a rectangle.

Step-by-step explanation:

Let's use X as the answer

3 feet is our starting position.

Every minute is 10 feet.

If we already have 3 feet then we know it has to be less than 5.

It can't be 4 since that would be 43.

Your Equation would be 3+10x=50

Our answer has to be 4.7 because

4.7*10=47

47+3=50

Your final equation would be:

Answer:

Well even though you dont need it now the answer is v = 42 squared

Step-by-step explanation:

I used g00g1e like a normal person would

0=(2/3)x +4

multiply by 3

0=2x +12

x =-6

(2/3)x +4 =0

2x +12 = 0

x =-6  = the x intercept

(2/3)x + 4 = kx +6

(2/3- k)x = 2

multiply by 3

(2-3k)x = 6

(2-3k)(-6) = 6

2-3k =-1

3k= 3

k = 1 makes the 2nd equation have the same x intercept = -6  or the point (-6,0)

Step-by-step explanation:

Finding the area of the canvas:

The canvas has sides measuring 3x - 3 and 4x + 1 inches. To find the area, we multiply the lengths of the sides. So, the area of the canvas is given by:

Area = (3x - 3) * (4x + 1)

= 12x^2 + x - 3

Therefore, the correct equation for the area of the canvas is A = 12x^2 + x - 3.

Finding the area of the circle created by the paint:

The rate at which the paint is spreading on the canvas is given by the function r(t) = 4t, where t represents time in minutes and r represents how far the paint has spread. The area of the circle created by the paint can be expressed as A[r(t)] = πr^2, where r(t) is the distance the paint has spread at time t.

Substituting the value of r(t) = 4t into the formula, we get:

A[r(t)] = π(4t)^2

= 16πt^2

Therefore, the area of the circle created by the paint is 16πt^2.

Determining if the circle will be at least 1300 in² in 5 minutes:

To check if the area of the circle will be at least 1300 in² in 5 minutes, we substitute t = 5 into the equation for the area:

A[r(5)] = 16π(5)^2

= 400π

Approximating the value of 400π, we get approximately, 1256.64.

Since 1256.64 is less than 1300, we can conclude that the area of the circle created by the paint after 5 minutes will not be at least 1300 in².
