Answer:

Area is  220 cm²

Step-by-step explanation:

Firstly divide the polygon into  rectangle and triangle

For rectangle  area

 Area = A  =  L × W = 11 × 18 = 198 cm²

For triangle

Area =  A =  1/2 bh = 1/2 × (15-11) × (18-7) = 1/2 × 4 ×11 = 44/2 = 22 cm²

Add them

     198 + 22 = 220cm²

Answer:

4. m<3 = 120

5. m<4 = 13

6. m<2 = 70

7. m<1 = 115

Step-by-step explanation:

4. m<3 = 120, this is because it is the same as m<1 due to vertical (congruent) angles

5. m<4 = 13, this is because it is the same as m<2 due to vertical (congruent) angles

6. m<2 = 70, this is because m<2 and m<3 are supplementary (adding up to 180) so we would subtract 180 - 110 (aka m<3) = 70 (aka m<2)

7. m<1 = 115, this is because m<1 and m<4 are supplementary (adding up to 180) so we would subtract 180 - 65 (aka m<4) = 115 (aka m<1)

Answer:

5. a) 2.140 + 1.725 = 3.865

b) 29.99 + 1.42 = 31.41

c) 6.157 - 1.009 = 5.148

6) 7.4 - 0.0022 = 7.2978 ✅

7.39 - 0.0012 = 7.3888

7. 140minutes / 2 hours and 20 minutes

Answer: B) The coordinate of L is (3,-2).

Step-by-step explanation:

Given that L is the midpoint of JK, we can apply the following equation to obtain the coordinates of point L:

L=(5+1/2, 3-7/2)

As a result of resolving this, we obtain

L=(6/2, -4/2)

L=(3,-2)

Therefore the answer is (3,-2)

Answer:

  ln(125) ≈ 4.828314

Step-by-step explanation:

The relevant log relation is ...

  log(a^b) = b·log(a)

__

This means your expression is equivalent to ...

  3·ln(5) = ln(5^3) = ln(125) ≈ 4.828314

__

The "exact" answer is ln(125).

Answer:

90% is close to 75

Step-by-step explanation:

90% of a number would be 3 times 30% of a number. As a result we can assume 90% of the number would be around 3(25) or 75

Using statistical concepts, it is found that the variance for this data set is of 22 oz squared.

From the second bullet point, the variance can also be interpreted as the sum of squared deviations divided by the sample size.

In this problem, the sum of squared deviations is 220 and the sample size is 10, hence, the variance for this data set is of 22 oz squared.

The solution to the system of equations will be (x, y) = (10,20).

In a mathematical equation, two expressions—which may or may not include variables or integers—are declared to be equal. The main motivations for the development of mathematics have been attempts to methodically address the underlying issues with equations.

It is given that, the equations are y=2x and y=3x-10.

Y=2x. . . . (1)

Y=3x-10. . . . (2)

put the value of y in 1 eq in 2 eq in order to find the value of x.

y= 3x - 10

2x = 3x - 10

x = 10

Put the value of x in 1 eq in order to get the value of y,

y = 2x

y = 2 × 10

y = 20

Pair formed

(x , y) = (10,20)

Thus, the solution to the system of equations will be (x, y) = (10,20).

Step-by-step explanation:

Y-intercept

-4x + 3y = -30

-4(0) + 3y = -30

3y = -30

y = -10

(0, -10)

X-intercept

-4x + 3y = -30

-4x + 3(0) = -30

-4x = -30

x = 15/2

x = 7.5

Answer:

Area = 142.5 square inches

Step-by-step explanation:

So your shape is kind of a little house. The bottom part is a rectangle 9 × 9.5. The area of the rectangle is

Area = length×width

= 9 × 9.5

= 85.5

The "roof" of the little house is a triangle. The area of a triangle is 1/2×base×height

Now, the base of the "roof" is the same as the floor of the house, 9.5 inches.

The height of the whole thing is 21 inches. If we take away the rectangle's wall-height, we'll get the height of the "roof".

Roof height= 21 - 9

= 12 inches

Area_roof

=1/2 × base × height

=1/2 × 9.5 × 12

= 57 square inches

Total area is bottom plus roof (the rectangle and the triangle)

Total Area

= 85.5 + 57

= 142.5 sq in

Answer:

(Choice A) 2(3d+3) & (Choice C) (3d+3)+(3d+3)

Step-by-step explanation:

[tex]4D + 6 + 2D = 6D + 6 = 2(3D + 3)[/tex] <--- A is correct

[tex]4D + 6 + 2D = 6D + 6 = 6(D +1)[/tex] < --- B is NOT correct

[tex]4D + 6 + 2D = 6D + 6 = 3d + 3d + 3 + 3 = (3d + 3)+(3d +3)[/tex] by associative and commutative properties

   so C is correct

A and C are both correct.

Answer:

Choices A and C

Step-by-step explanation:

Start by simplifying the original expression.

4d+6+2d

Combine like terms

6d+6

Now, we can check each expression to see if it is equivalent to 6d+6

Choice A:

2(3d+3)

Distribute the 2

2(3d)+2(3)

6d+6 --> It is equivalent!

Choice B:

6(d+6)

Distribute the 6

6(d)+6(6)

6d+36 --> No, it is not equivalent

Choice C

(3d+3)+(3d+3)

The parentheses aren't necessary so we can take them out.

3d+3+3d+3

Combine like terms

6d+6 --> It is equivalent!

Answer:

letter A that's the answer

the other person is wrong the answer is C
