3 Units8 Units9 Units13 Units21 UnitsWhat Is The Area Of The Figure Insquare Units.

Answers

Answer 1

Answer:

Area = 132 Square units

Step-by-step explanation:

Looking at the diagram, the top horizontal chord distance that's missing is calculated as;

21 - (9 + 3) = 9 units

Total distance of top horizontal chord = 9 + 3 = 12 units

Now, formula for area of trapezium is;

Area = ½(a + b)h

Where h is height = 8 units

The parallel sides are a & B.

In this case; a = 12 units

b = 21 units

Thus;

Area = ½(12 + 21)8

Area = 4 × 33

Area = 132 Square units

consider the figure shown below. Match the angles given in the first column with their equivalent degree Measure given in the first row

Answers

Answer:

∠3 = 115°

∠8 = 75°

∠6 = 105°

∠11 = 115°

∠9 = 65°

∠4 = 65°

Step-by-step explanation:

∠3 = 180 - 65 =115° because they are supplementary

∠8 = 75° because it is vertical to 75°

∠6 = 180 - 75 = 105° because they are supplementary

∠11 = 115° because it is corresponding to ∠3

∠9 = 65° because it is corresponding to ∠1

∠4 = 65° because it is vertical to 65°

Applying the definition of special angle pairs, the given angles and their respective equivalent degree measures are:

m<3 = 115°m<8 = 75°m<11 = 115°m<9 = 65°m<4 = 75°

Given the following:

m<1 = 65°m<5 = 75°

Thus:

<3 and <1 are supplementary angles, therefore,

m<3 = 180° - 65°

m<3 = 115°

<8 and <5 are vertical angles, therefore,

m<8 = 75°

<6 and <8 are supplementary angles, therefore,

m<6 = 180° - 75°

m<6 = 105°

<11 and <3 are corresponding angles, therefore,

m<11 = 115°

<9 and <1 are corresponding angles, therefore,

m<9 = 65°

<4 and <2 are vertical angles, therefore,

m<4 = 75°

What would the graph of
Х/4.8 < 1.25 look like?

Answers

Answer:

Step-by-step explanation:

x/4.8 < 1.25                             Multiply both sides by 4.8

4.8 x /  4.8 < 1.25*4/8

x < 6

What this means is that every every number less than 6 is a solution to this inequality.

Graph 32 (shown below is a red area. The important thing to note is that the boundary at 6 is dotted which means it is not included in the solution.

What you want is more closely related to a number line and sort of looks like this

Explanation

The top line is the actual number line or the graph

o------- is the way it is made.

The second line are the number divisions of the number line

The third line shows which way the inequality goes and that it is open at 6. Open means that you can get close to 6 but you can't touch 6.

The width of the rectangle
is one-fourth of its length.
If the perimeter is 40 cm,
find the dimensions of the
rectangle.
4w = L
2L + 2w = 40

Answers

Answer:

84cm^2

Step-by-step explanation:

P=2l+2w

We are given,

P=40cm

l=2w+2

Plug these into the first formula and solve for the dimensions,

length and width, of the rectangle:

40=2(2w+2)+2w              Simplify

40=4w+4+2w

40=6w+4

36=6w

6=w OR the width is 6cm, therefore,

the length is

l=2(6)+2

l=14cm

To calculate the area of a rectangle, A=lw,

plug the length,14cm, and the width, 6cm, into this formula

A=(14)(6)

A=84cm2 OR the area of the rectangle is 84cm^2

Step-by-step explanation:

This is a question of experimental probability, in which the probability from the previous outcomes is the probability for the next outcome.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Select all expressions that are equivalent to 6(7a + 9b).
(1 Point)
3(14a + 18b)
2(11a + 13b)
42a + 9b
42a + 546

Answers

Answer:

6(7a + 9b) = 3(14a + 18b)

Step-by-step explanation:

We need to find the equivalent expression for the given expression i.e. 6(7a + 9b).

We can use the distributive property here such that,

a(b+c) = ab + ac

We have, a = 6, b = 7 and c = 9

6(7a + 9b) = 6(7a) + 6(9b)

= 42a + 54b

or taking 3 common from the above expression.

= 3(14a+18b)

Hence, the correct option is (a).
