Answer:

(3, 15) and (4, 12)

Step-by-step explanation:

x2 - 7x+12 = 0 factors to (x - 4)(x - 3) = 0, and so x:  {3, 4}.

Since y= -3x + 24, y = 15 when x = 3 and y = 12 when x = 4.  The solutions are thus (3, 15) and (4, 12).  This is the third answer choice.

Answer:

see the explanation

Step-by-step explanation:

Y = –x2 + 4x + 12

y = –3x + 24

so

–x2 + 4x + 12 =  –3x + 24

x^2 -7x + 12 = 0

(x - 4)(x - 3) = 0

x - 4 =0; x =4

x - 3 = 0; x= 3

y = –3x + 24 = -3(3) + 24 = -9+24 = 15 (when x = 3)

y = –3x + 24 = -3(4) + 24 = -12+24 = 12 (when x = 4)

answer

(3, 15) and (4, 12)

Answer:

n = -15         and          m = -3

Step-by-step explanation:

To solve the given system of equation, we will follow the steps below:

n = 5m ----------------------------------------------------------------------------(1)

n = [tex]\frac{2}{3} m -13[/tex] ---------------------------------------------------------------------(2)

substitute for n= 5m in equation (2)

5m =  [tex]\frac{2}{3} m -13[/tex]

subtract [tex]\frac{2}{3} m[/tex] from both-side of the equation

5m -  [tex]\frac{2}{3} m[/tex]  = [tex]\frac{2}{3} m[/tex] -  [tex]\frac{2}{3} m -13[/tex]

At the right-hand side of the equation  [tex]\frac{2}{3} m[/tex]  will cancel-out leaving us with just -13

5m -  [tex]\frac{2}{3} m[/tex]  = -13

[tex]\frac{15m - 2m }{3}[/tex] = -13

[tex]\frac{13m}{3}[/tex] = -13

multiply both-side of the equation by 3

3 ×  [tex]\frac{13m}{3}[/tex] = -13 ×  3

At the left-hand side of the equation 3 will cancel-out 3 leaving is with just 13m

13m = -39

Divide both-side of the equation by 13

13m/13  = -39/13

m = -3

substitute m = -3 in  equation (1)

n = 5m

n = 5 (-3)

n = -15

Therefore, n = -15         and          m = -3

Answer:

51 gal

Step-by-step explanation:

Find the area of the wall you need to paint:

12 m * 80 m = 960 m^2

Use conversion rate to convert square meters to square feet (first, make the conversion rate into square meters instead of regular meters):

1 ft / 0.3048 m -> 1^2 ft / 0.3048^2 m^2

960 m^2 * (1 ft^2 / 0.3048^2 m^2)

Square meters cancel out, we are left with square feet:

960 * (1 ft^2 / 0.3048^2) = 10333.354 ft^2

Now, find how many gallons of paint by dividing by 200 square feet:

10333.354 ft^2 / 200 =~ 51.66 gal

Round up to the nearest whole number:

51.66 =~ 51 gal

The smallest whole number of gallons require to paint the wall is 52 gallons.

1 gallon of paint = 200 ft²

I foot = 0.3048 metres

Dimension of wall :

12 metre by 80 metre

Converting the dimension to feet :

12 meter / 0.3084 = 39.370078 feets

80 meter / 0.3084 = 262.46719 feets

Hence, the area of the wall in feet²:

Area = Length × width

Area of wall = 262.46719 × 39.370078 = 10333.3537427408 ft²

Let number of falloms required = x

Since,

1 gallon = 200 ft²

x gallons = 10093.516 ft²

Cross multiply :

200x = 10093.516

x = 10333.35374274082 / 200

x = 51.6667687137041 gallons

x = 52 gallons

Hence, the smallest number of gallons required to paint the wall is 52 gallons of paint

Answer:

the median is 80.5

Step-by-step explanation:

first we put them in order

75,76,77,79,80,81,85,86,90,91

the median is the middle number...however, in cases where there are an even number of numbers, ur gonna have 2 middle numbers....so u take the average of those 2 numbers...basically, u add them and divide by 2.

So we have 2 numbers in the middle.....we add them and divide by 2 to get the median.

(80 + 81) / 2 = 161/2 = 80.5 <== the median

Answer: d all others are 3d

Step-by-step explanation:

Answer:

D) None of the above

Step-by-step explanation:

This is because all of the shapes above are examples of 3D shapes. A 3D shape would have the dimensions of length and width and height. However a 2D shape would only have the dimensions of length and width.

An example of a 2D shape is a rectangle. as it consists of a length and a width, but does not have a height.

On the other hand a £D shape such as a cube would have a length, width and a height.

Step-by-step explanation:

you gotta take the "answer" so in this case its 3m with something to the power and the square root of 7, which is 2.6. Then you take 3m and add it to 2.6, which is 5.6m. Then you take 5.6 and take the to the 17th power and do that which is 5.2e+12. You simplify that and thats the answer. I'm pretty sure.

Answer:

1) Perimeter of the parallelogram = 32 cm

2) The angles of the rhombus include 53°, 53°, 127° and 127°.

3) The length of the median drawn to the smaller of the legs = 13 cm

4) The sides of the rectangle are 8 cm and 12 cm

1) Периметр параллелограмма = 32 см

2) Углы ромба включают 53 °, 53 °, 127 ° и 127 °.

3) Длина медианы обращена к меньшей из ног = 13 см.

4) стороны прямоугольника 8 см и 12 см

Step-by-step explanation:

English Translation

1) Find the perimeter of the parallelogram, the sides of which are 5 cm and 11 cm.

2) One of the angles of the rhombus is 53 °. Find the other angles of the rhombus.

3) The legs of a right triangle are 12 cm and 10 cm. Find the length of the median drawn to the smaller of the legs.

4) Find the sides of the rectangle if they are related as 2: 3, and the area of ​​the rectangle is 96 cm².

Solution

1) Find the perimeter of the parallelogram, the sides of which are 5 cm and 11 cm.

A parallelogram has each of its opposite sides to be equal in length.

Perimeter of a parallelogram = 2(l + b)

l = 11 cm

B = 5 cm

Perimeter = 2(11 + 5) = 32 cm

2) One of the angles of the rhombus is 53 °. Find the other angles of the rhombus.

A rhombus is a quadilateral with the sum of its internal angles equal to 360°. Also, opposite angles of a rhombus are equal in magnitude.

Let the unknown other complementary angle be x.

53° + 53° + x + x = 360°

2x + 106° = 360°

2x = 360° - 106° = 254°

x = (254°/2) = 127°

The angles of the rhombus include 53°, 53°, 127° and 127°.

3) The legs of a right triangle are 12 cm and 10 cm. Find the length of the median drawn to the smaller of the legs.

The median is the line drawn from the vertex opposite a triangle's side to the midpoint of that side.

The median described is drawn in the attached image to this question.

From the image, the small triangle is a right angled triangle, hence, the length of the median is given by Pythagoras theorem.

(Median)² = 12² + 5² = 169

median = 13 cm

4) Find the sides of the rectangle if they are related as 2: 3, and the area of ​​the rectangle is 96 cm².

Let the breadth and length of the rectangle be x and y respectively.

x:y = 2:3

(x/y) =(2/3)

x = (2y/3)

Area of a rectangle = length × breadth = x × y = xy = 96

x = (2y/3)

(2y/3) × y = 96

y² = (96×3/2) = 144

y = 12 cm

x = (2y/3) = (2×12/3) = 8 cm

Answer:

Set B i.e., 5 , 7 , 8 represent the side of acute angled triangle.

Step-by-step explanation:

Given: Set of numbers.

To find: Set that represent sides of an acute angled traingle.

We use the following result:

When given 3 triangle sides then to determine if the triangle is acute angled , right angled or obtuse angled.

First find Square all 3 sides, then Sum the squares of the 2 shortest sides and then Compare the sum to the square of the last side.

if sum > Square of last side ⇒ it is Acute Triangle

if sum = Square of last side ⇒ it is Right Triangle

if sum < Square of last side ⇒ it is Obtuse Triangle  

a). 4  , 5 , 7

4² = 16 ,  5² = 25 , 7² = 49

16 + 25 = 41

∵ 41 < 49

⇒ It is an Obtuse Traingle.

b). 5 , 7 , 8

5² = 25 , 7² = 49 , 8² = 64

25 + 49 = 74

∵ 74 > 64

⇒ It is an acute Triangle.

c). 6 , 7 , 10

6² = 36 , 7² = 49 , 10² = 100

36 + 49 = 85

∵ 85 < 100

⇒ It is an Obtuse Triangle.

d). 7 , 9 , 12

7² = 49 , 9² = 81 , 12² = 144

49 + 81 = 130

∵ 130 < 144

⇒ It is an Obtuse Triangle.

Therefore, Set B i.e., 5 , 7 , 8 represent the side of acute angled triangle.
