Step-by-step explanation:

1) the given octagon can be imagined as 8 triangles (see the attachment). In order to calculate the required area of the octagon, it is enough to calculate the area of one triangle then increase it 8 times:

2) area of one triangle is:

37*31/2 [in²].

Answer:

A = -81

B = 4/9

Step-by-step explanation:

An equation that has infinite solutions suggests that the left side equals the right side.

Expand brackets:

      [tex]\dfrac23(12-Ax)-4 = 9(6 x + B)[/tex]

[tex]\implies 4-\dfrac23Ax = 54x+9B[/tex]

Equate coefficients of x:

[tex]\implies -\dfrac23A=54[/tex]

[tex]\implies A=-81[/tex]

Equate constants:

[tex]\implies 4=9B[/tex]

[tex]\implies B=\dfrac49[/tex]

Answer:

Answer: OD 81007 in.2

Step-by-step explanation:

Use formula for area of circle, which is A = πr²

The radius is squared, so if the radius or a new circle is 6 times larger (multiplied by 6), the difference in area will be 36 times greater.  So the area is

225π(36) = 8,100π

Answer:

Question:

A circle has an area of 225[tex]\pi[/tex] square inches.  If the radius of the circle is multiplied by 6, then what is the area of the new circle?

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

area of a circle = [tex]\pi r^2[/tex]   (where r is the radius)

⇒ [tex]\pi r^2=225\pi[/tex] in²

If the radius is multiplied by 6, then r = 6r

⇒ area = [tex]\pi (6r)^2=36\pi r^2[/tex]

Therefore, if [tex]\pi r^2=225\pi[/tex]

then [tex]36\pi r^2 = 36 \times 225\pi =8100\pi[/tex]

Answer:

x = 2 and y = 3

Step-by-step explanation:

To find the x- intercept, let y = 0 in the equation and solve for x

3x + 2(0) = 6

3x + 0 = 6

3x = 6 ( divide both sides by 3 )

x = 2 ← x- intercept

To find the y- intercept, let x = 0 in the equation and solve for y

3(0) + 2y = 6

0 + 2y = 6

2y = 6 ( divide both sides by 2 )

y = 3 ← y- intercept

Answer:

total blocks are 20 and prisms are 28

Step-by-step explanation:

There are 20 blocks needed for tower A, and 43.75 blocks needed for tower B

From the tape diagrams, we have the following ratio

Prism : Pyramid = 4 : 1

From the table, we have:

Tower A = 16 prisms

So, the ratio becomes

16 : Pyramid = 4 : 1

Multiply the ratio on the right-side by 4

16 : Pyramid = 16 : 4

By comparison, we have:

Pyramid = 4

This means that, 4 pyramid blocks are needed for tower A

So, the total number of blocks needed is:

Total = Pyramid + Prism

This gives

Total = 4 + 16

Evaluate the sum

Total = 20

Hence, there are 20 blocks needed for tower A

For table B, we have:

Tower A = 35 prisms

So, the ratio becomes

35 : Pyramid = 4 : 1

Express as fractions

[tex]\frac{Pyramid}{35} = \frac 14[/tex]

Multiply through by 35

Pyramid = 8.75

This means that, 8.75 pyramid blocks are needed for tower B

So, the total number of blocks needed is:

Total = 8.75 + 35

Evaluate the sum

Total = 43.75

Hence, there are 43.75 blocks needed for tower B

Step-by-step explanation:

Answer:

(2) $1,699.50

Step-by-step explanation:

A(t) = P(1 + r/n)^nt

1500(1 + .025/12)^5*12

= $1699.50

$1,699.50 represents the value of an investment with a principal of $1500 with a nominal interest rate of 2.5% compounded monthly after 5 years.

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

Given that an investment with a principal of $1500 with a nominal interest rate of 2.5% compounded monthly after 5 years,

Amount = P(1+r/n)^nt

= 1500(1+0.25/12)^5*12

= $1699.50

Hence, $1,699.50 represents the value of an investment with a principal of $1500 with a nominal interest rate of 2.5% compounded monthly after 5 years.

Answer:

  yes; AB ⊥ BC

Step-by-step explanation:

If the triangle is to be a right triangle, the slopes of two sides must be opposite reciprocals. The slope is the ratio of rise to run.

  mAB = rise/run = -3/4

  mBC = rise/run = 4/3

These slopes, -3/4 and 4/3 are opposite reciprocals (their product is -1), so ...

  AB ⊥ BC . . . the triangle is a right triangle

Answer:

53

Step-by-step explanation:

It is either an alternate angle or an opposite angle of the 53 shown.

We know that angles on a straight line add up to 180, so:

53+x=180

x=180-53

x=127

We know that the indicated angle plus x would give 180, so:

?+x=180

?+127=180

?=180-127

?=53

Answer:

[tex]c=35r+10[/tex]

Step-by-step explanation:

We need to create a linear equation in the form: c = mr + b

(where m is the slope and b is the y-intercept)

Choose two ordered pairs from the table:  (2, 80) and (4, 150)

Let [tex](r_1,c_1)[/tex] = (2, 80)

Let [tex](r_2,c_2)[/tex] = (4, 150)

Calculate the rate of change (slope of linear equation) by dividing the change in c by the change in r:

[tex]\textsf{slope} \ m=\dfrac{c_2-c_1}{r_2-r_1}=\dfrac{150-80}{4-2}=35[/tex]

Now use point-slope form of linear equation to create final equation:

      [tex]c-c_1=m(r-r_1)[/tex]

[tex]\implies c-80=35(r-2)[/tex]

[tex]\implies c=35r+10[/tex]

Step-by-step explanation:

the total sugar bags to be distributed= x=48

the total rice bags to be distributed= y=72
each family can take a package containing= 1x +2y
as each family can have 2 rice bags thus we can estimate the total number of families that can benefit by diving total no of rice bags by 2 which will be = 72/2 =36

the rice can be divided into 36 families
while the sugar bags can be divided into 48 families
as these have to be divided into packages so there will be 36 packages
that can be distributed into 36 families.

  see "additional comment" regarding listing pairs

Step-by-step explanation:

There are a number of ways angles can be identified as congruent. In each case, the converse of the proposition is also true.

In these exercises, pairs of angles need to be examined to see which of these relations may apply.

__

Left

ABCD is a parallelogram, so the congruent angles are opposite angles and any that are vertical or corresponding:

  ∠BAC ≅ ∠BDC ≅ ∠EDF ≅ 110° (3 pairs)

  ∠ACD ≅ ∠ABD ≅ ∠BDE ≅ ∠CDF ≅ 70° (6 pairs)

Center

  ∠1 ≅ ∠4 ≅ 66° (1 pair) . . . . vertical angles

  ∠2 ≅ ∠3 ≅ ∠5 ≅ ∠6 ≅ 57° (6 pairs) . . . . marked with the same measure, and their vertical angles

Right

Assuming that lines appearing to go in the same direction actually do go in the same direction, the only pair of congruent angles in the figure is ...

  ∠2 ≅ ∠3

__

Left

Corresponding angles in congruent triangles are congruent. Here, the congruent triangles are ΔACD ≅ ΔCAB. So, the pairs of congruent angles are ...

  ∠ACD ≅ ∠CAB (30°)

  ∠CDA ≅ ∠ABC (90°)

  ∠DAC ≅ ∠BCA (60°)

Right

The corresponding angles and any vertical angles are congruent. This means all the odd-numbered angles in the figure are congruent, and all the even-numbered angles in the figure are congruent. The marked 72° angles show the "horizontal" segments are parallel by the converse of the corresponding angles theorem.

  ∠1 ≅ ∠3 ≅ ∠5 (72°) (3 pairs)

  ∠2 ≅ ∠4 ≅ ∠6 (108°) (3 pairs)

_____

Additional comment

The question asks you to list pairs of congruent angles. When 3 things are congruent, they can be arranged in 3 pairs:

  a ≅ b ≅ c   ⇒   (a≅b), (a≅c), (b≅c)

Similarly, when 4 things are congruent, they can be arranged in 6 pairs:

  a ≅ b ≅ c ≅ d   ⇒   (a≅b), (a≅c), (a≅d), (b≅c), (b≅d), (c≅d)

In the above, we have elected not to list all of the pairs, but to list the set of congruences from which pairs can be chosen.
