Answer:

Check bolded below

Step-by-step explanation:

1)radius = 10 in (given), diameter = 2*radius = 2(10 in) = 20 in

formula for circumference => 2πr => 2π(10)

circumference = 20π in

2)diameter = 12 ft (given), radius = 1/2*diameter = 1/2(12 ft) = 6 ft

formula for circumference => 2πr => 2π(6)

circumference = 12π ft

3)radius = 3 m (given), diameter = 2*radius = 2(3 m) = 6 m

formula for circumference => 2πr => 2π(3)

circumference = 6π m

4)diameter = 18 cm (given), radius = 1/2*diameter = 1/2(18 cm) = 9 cm

formula for circumference => 2πr => 2π(9)

circumference = 18π cm

1.

radius = 10 in

diameter = 10 × 2 = 20 in

formula = π × d

circumference = π × 20 = 62.83 in

2.

radius = 12 ÷ 2 = 6 ft

diameter = 12 ft

formula = π × d

circumference = π × 12 = 37.70 ft

3.

radius = 3 m

diameter = 3 × 2 = 6 m

formula = π × d

circumference = π × 6 = 18.85 m

4.

radius = 18 ÷ 2 = 9 cm

diameter = 18 cm

formula = π × d

circumference = π × 18 = 56.55 cm

Answer:

  5/12

Step-by-step explanation:

Since Pedro had 1/3 of the book remaining at the end of the day, he had read a total of 2/3 of the book. If n represents the amount read at night, you have ...

  1/4 + n = 2/3

  3 +12n = 8 . . . . . multiply by 12

  12n = 5 . . . . . . . .subtract 3

  n = 5/12 . . . . . .  divide by 12

Pedro read 5/12 of the book at night.

_____

Since Pedro reads only a fraction of the book, it is not a "mixed number."

__

The solution is equivalent to finding the difference ...

  2/3 - 1/4

  = 8/12 - 3/12 = 5/12

Answer:

314,880

Step-by-step explanation:

If the population decreases by 1.6% per year, this means the population is 98.4% of the population of the previous year. What this means is we can multiply the current population, 320,000, by 98.4/100, as 98.4/100 is equivalent to 98.4%. This gets us 314,880.

Answer:

314880

Step-by-step explanation:

Answer:

a.The diagonals are congruent.

d. Opposite angles are congruent.

Step-by-step explanation:

From the above question, we are told that:

All the sides of a quadrilateral measure 5 cm.

This means this quadrilateral is a square.

The properties of a square states that:

1) Opposite sides of a square are equal each other or congruent.

2) Opposite angles are equal each other or congruent

3) Consecutive angles of a square are supplementary angles which means that they add up to 180.

4) A square has two diagonals and they are congruent or equal to one another.

Therefore, the correct options are options a and d

Answer:

One possible solution be -

Mrs. Cho is brings type A cans = 10

Mrs. Cho is brings type B cans =  3

Step-by-step explanation:

Let us assume

Mrs. Cho is brings type A cans = x

Mrs. Cho is brings type B cans = y

As given,

For a type A can, she gets 5 cents and For type B can, she gets 10 cents

As we have x Type A cans and y Type B cans

And she has redeemed  no more than 95 cents

⇒5x + 10y ≤ 95           .......(1)

Also given,

She has redeemed at least 11 cans

⇒ x + y ≥ 11           ........(2)

∴ we get

x + y ≥ 11  

5x + 10y ≤ 95

By applying graphical method , we get

The equations become

5x + 10y = 95       .......(1)

x + y = 11              ........(2)

Table for equation (1) -

x                   y

0                    9.5

19                    0

Table for equation (2) -

x               y

0              11

11              0

The two lines intersect at point (3, 8)

So the possible combinations are in the shaded portion which is covered by both the lines.

One possible combination is ( 10, 3) which lies in the shaded region.

So,

Mrs. Cho is brings type A cans = x = 10

Mrs. Cho is brings type B cans = y = 3

Answer:

1: b. YZ, see "geometric mean theorem" in Wikipedia

2: a. sin Y = 7.4/10.9 ≈ 0.68,  sine = opposite/hypotenuse

3: c. tan P = 8.5/16 ≈ 0.53, tangent=opposite/adjacent

4: a. AC = 11.7, sine = opposite/hypotenuse, sin(43) = 8/AC

5. KM = 10.68 use Pythagorean Theorem

measure of angle M = 35 degrees, use definition of tangent

measure of angle K = 55 degrees,  M and K are complementary angle

The term that completes the equation is YZ.

Option D is the correct answer.

We have,

From the figure,

∆WXY and ∆XYZ

∠WXY = ∠XZY = 90

∠ZYX = ∠XYW (common angle)

∆WXY ≅ ∆XYZ

And,

∆WXY and ∆WXZ

∠WXY = ∠WZX = 90

∠YWX = ∠XWZ (common angle)

∆WXY ≅ ∆WXZ

Now,

From (1) and (2),

∆XYZ ≅ ∆WXZ

This means,

The corresponding sides are proportional.

We can write as,

YZ/XZ = XZ/ZW

XZ² = WZ x YZ

Thus,

The term that completes the equation is YZ.

Answer:

x=16

Step-by-step explanation:

27/45=(2x+7)/(4x+1)

cross multiply

27(4x+1)=45(2x+7)

108x+27=90x+315

108x-90x=315-27

18x=288

x=288/18

x=16

Looking at the image, The triangle shown below are similar. The value for  x is 16.

Note that in the triangle given, the shapes are similar. Therefore:

27/45 = 2x + 7/  4x + 1

3/5 = 2x + 7/  4x + 1

So:

3 (4x + 1) = 5 (2x + 7)

12x + 3 = 10x + 35

12x - 10x = 35-3

2x = 32

x = 32/ 2

x = 16

Therefore, the value of x is 16.

Answer:

Step-by-step explanation:

example

we are given: slope = 5, y-intercept = 9

y=mx+b

we just plug it in

y=5x+9

Answer:

Y intercept : ( 0 , 25 )

Step-by-step explanation:

Answer:

Step-by-step explanation:

We need to convert function to slope-intrcept form y=mx+b, where:

-0.4x + 0.05y - 1.25 = 0         {multiply both sides by 20}

-8x + y - 25 = 0                    {add (8x+25) to both sides}

y = 8x + 25     ⇒   b = 25

Therefore y-intercept of the line is (0, 25)
