Answer:

140 inches

Step-by-step explanation:

Find the area of the square.

4 + 10 = 14 (Length)

11 + 4 = 15 (Breadth/Width)

Area = 14 x 15 = 210 inches

Find the area of the 2 unshaded squares in the square.

Area of square at the top = 4 x 4 = 16 inches

Area of square at the bottom = 6 x 9 = 54 inches

Add the 2 squares of the area together.

16 + 54 = 70 inches

Now deduct the area of the huge box by the area of the 2 unshaded squares.

210 - 70 = 140 inches

Answer:

No.

Step-by-step explanation:

53 + 35 = 88, add 18 = 106.

Answer:

no

Step-by-step explanation:

18x18 + 35 x35 = 53x53

324 + 1225 = 2809

1549 =\ 2809

Answer:

86%

Step-by-step explanation:

28 were placed on suspension

200 are total (including that 28)

not placed on suspension are the rest, so 200-28=172

172 out of 200 = 86% not placed on suspension

Answer:

86% Pls consider marking brainliest if correct.

Step-by-step explanation:

Okie lets see

In all : 200

Removed : 28

To find percentage : 200-28/200

200 - 28 = 172

172/200 = (172/2)/(200/2)

I did this because 200 is 100x2, and because percentage is over 100

172/2 = 86

200/2 = 100

86/100 = 0.86 = 86%

Answer:

96º

Step-by-step explanation:

The sum of a triangle's angles is 180. We can find t by subtracting 58 and 38 from 180. 180-58-38=84. x and t and supplementary angles, so x is 180-t which is 180-84=96º.

Answer:

a = 4

Step-by-step explanation:

a = 4

If a = 4, then both lines have the same slope and different y-intercepts. That makes both lines parallel. Since the lines never intersect, there is no solution.

Answer:

x can not equal zero, as it would cause division by zero.

Step-by-step explanation:

First, let's make one equation out of them and see what we get.  Because both of them have y on the left, we can say that the two right sides are equal, giving us:

4x - 9 = ax + 6

If we solve for a, we get:

ax + 6 = 4x - 9

ax = 4x - 15

a = 4 - 15 / x

With that arrangement we can see clearly that x can not be equal to zero, as it would give us division by zero.

Answer:

C, D

Step-by-step explanation:

In a triangle, the length of any side must be least than the sum of the lengths of the other 2 sides.

That means

3x < 19 + 6

3x < 25

x < 25/3

x < 8 1/3

Step-by-step explanation:

Opposite angles are equal in a parallelogram. Therefore 2 angles are 112°. Angles in a parallelogram or any quadrilateral are equal to 360°. To find the remaining sides: 360-(112×2) and divide your answer by 2.

Answer:

[tex]\huge\boxed{\sf x = 16}[/tex]

Step-by-step explanation:

Using Pythagoras Theorem since it is a right angled triangle.

Where,

Base = 12

Perpendicular = x

Hypotenuse = 20

[tex](Hypotenuse)^2=(Base)^2+(Perpendicular)^2[/tex]

[tex](20)^2=(12)^2+x^2\\\\400 = 144 + x^2\\\\Subtract \ 144 \ to \ both \ sides\\\\400-144=x^2\\\\256 =x^2\\\\Take\ Sq. \ root\ on \ both \ sides\\\\\sqrt{256} =x^2\\\\16 = x\\\\x = 16\\\\\rule[225]{225}{2}[/tex]

Answer: MN = 8.5

Step-by-step explanation:

Form it into a right triangle with MN being the hypotenuse (side opposite the right angle)

To make this a right triangle, plot a point at (8,-2) and connect the sides. The lengths of the legs that form the right angle are both 6 units. Use the Pythagorean theorem to solve for length of MN. a^2+b^2=c^2. (a and b are the legs that form the right angle and c is the hypotenuse)

6^2+6^2=c^2

36+36=c^2

72= c^2

8.48528137 = c.

Question says to round to nearest tenth of a unit

8.5 = c (line MN)

Answer:

4y^{2}+3y  

Step-by-step explanation:

First you need to distribute the values.  

(4y+3)(2y) Using the "Rainbow Method" to multiply the polynomials  

You Should get  

8y^{2}+6y  

Since this is the area of the rectangle and we need to find the area of the shaded region you need to dived 8y^{2}+6y in half because the shaded region is half of the rectangle.  

8y^{2}+6y/2  

Doing this you will get  

4y^{2}+3y

9514 1404 393

Answer:

  yes

Step-by-step explanation:

The side lengths of the triangle are 5, 12, and 5+8 = 13. We can check to see if they satisfy the Pythagorean theorem, which would indicate a right triangle.

  5² + 12² = 25 +144 = 169 = 13²

These sides do satisfy the relationship between sides for a right triangle, so angle A is a right angle. That is the case when segment AB is a tangent to the circle.

  Yes, AB is a tangent.

Answer:

A

Step-by-step explanation:

Area of the unshaded region = 95/360  * 3.14 * (5*√2)^2

Area of the unshaded region = 95/360 * 3.14 * 50

Area of the unshaded region = 41.43

Area of the entire circle = pi r^2

Area of the entire circle = 3.14 * (5√2)^2

Area of the entire circle = 157

Area of the shaded part = The whole circle's area - the unshaded part

Area of the shaded part = 157 - 41.42

Area of the shaded part = 115.57

Answer:

D. 60, 60, 60

Step-by-step explanation:

In an equilateral triangle, all sides are equal and equal to 180 when added together. because 60×3 is equal to 180, D is the right answer. I hope this helps you!

The angle measurements found in an equilateral triangle are 60°, 60°, 60°

An equilateral triangle is an angle that has equal angles and equal sides. It implies that all the sides of the angle contain the same length.

We can also say that an equilateral triangle is also equiangular since it has equal angles. If we recall, we know that the sum of angles in a triangle is 180°.

For a triangle with equal sides, it implies that each length will possess;

= 180°/3

= 60° each.
