Christi alters a skirt. She cuts 7 inches off the bottom of the skirt and then adds a 5-inch ruffle to the skirt's remaining bottom edge. Which expression best represents the final length of the skirt?

Answer:

A. is correct

Step-by-step explanation:

sqrt3*sqrt12 can be rewritten as √3·√12, which can be extended to

√3·√3·√4.

Note that √4 = 2 and that (√3)^2 = 3,

so the final result is 2*3, or 6 (a rational number).

A. is correct:  √3 and √12 are both irrational, but their product is rational.

Answer:

a) Side lengths

= GH = 5 units

HI = 6 units

GI = 7.81 units

b) Angle measures

Angle G = 39.81°

Angle H = 90°

Angle I = 50.2°

Step-by-step explanation:

The coordinates of the vertices of △GHI are G(−7,2), H(−2,2), and I(−2,8). Find the side lengths to the nearest hundredth and the angle measures to the nearest degree.

Step 1

We find the side lengths using the coordinates formula

= √(x2 - x1)² + (y2 - y1)²

When we are given vertices (x1, y1) and (x2 , y2)

Coordinates of the vertices of △GHI are G(−7,2), H(−2,2), and I(−2,8).

For side length

GH = G(−7,2), H(−2,2)

= √(-2 - (-7))² + (2 - 2)²

= √(-2 + 7)² + (0)²

= √5²

= √25

= 5 units

For side length HI

HI = H(−2,2), and I(−2,8)

= √(-2 -(-2))² + (8 - 2)²

= √(0)² + (6)²

= √36

= 6 units

For side length GI

G(−7,2), I(−2,8)

= √(-2 -(-7))² + (8 - 2)²

= √(5)² + (6)²

= √25 + 36

= √61

= 7.81 units

Step 2

Angle measures

We find this using Cosine rules

Angle a = arc cos (b² + c² - a²/2bc)

Hence:

Finding

Angle G = arc cos (6² + 7.81² - 5² / 2 × 6 × 7.81)

= 39.81°

Angle H = arc cos (5² + 6² - 7.81² / 2 × 5 × 6)

= 90°

Angle I = arc cos (5² + 7.81² - 5² / 2 × 5 × 7.81)

= 50.2°

Answer:

GH = 5, HI = 6, GI ≈ 7.81

m∠H = 90°, m∠G ≈ 50°, m∠I ≈ 40°

Answer:

29 degrees

Step-by-step explanation:

alternate interior angles are equal

The measure of angle LMQ in the parallelogram LMNQ is 29 degrees

From the diagram, we have the following parameters

Also, from the diagram, angles MQN and LMQ are alternate interior angles

This means that, both angles are congruent

So, we have:

[tex]\angle LMQ = \angle MQN[/tex]

This gives

[tex]\angle LMQ = 29^o[/tex]

Hence, the measure of angle LMQ in the parallelogram LMNQ is 29 degrees

Step-by-step explanation:

Answer: The height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.

Step-by-step explanation:

Let x= height of each fir tree, y = height of each pine tree.

As per given, we have

x+y = 21          (i)

4x=y+24        (ii)

From (ii),

[tex]4x-y=24[/tex]            (iii)

Add (i) and (iii), we get

[tex]5x=45\\\\\Rightarrow\ x=\dfrac{45}{5}\\\\\Rightarrow\ x=9[/tex]

Put value of x in (i), we get

[tex]9+y=21\Rightarrow y=12[/tex]

Hence, the height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.

Answer:

Each fir tree is  9  meters tall and each pine tree is  12  meters tall.

Answer:

17.75

Step-by-step explanation:

43.5 divided by 2 is 21.75

21.75 minus 4 equals 17.75

You're basically just using reverse operations to get back to the original number.

Answer:

Divide both sides by 3.

(x+2)^2=16

Square root both sides.

x+2= ± 4  (plus OR minus, can be either so we have to include both)

Minus 2 from both sides.

x=-2 ± 4

Add and minus the 4 to -2.

x = -2-4 = -6 and x=-2+4 = 2

Answer: x = -6, x = 2

Step-by-step explanation:

3(x+2)^2 = 48

(X+2)^2 = 16 —> divide both sides by 3.

(X+2) = 4 or -4 —> take square root. Remember plus or minus!

X + 2 = 4 —> make (x+2) equal to 4.

X = 2 <— solution.

X + 2 = -4 —> make (x+2) equal to -4.

X = -6 <— solution.

Month since April                                   Number of Ants

          0                                                         10,000

           1                                                         30,000

          2                                                         90,000

          3                                                        270,000

          4                                                         810,000

Every month, the ant population triples so the multiply the previous population by 3 to find out the new population.

0 months from April = 10,000 * 1 = 10,000 ants

1 month from April = 10,000 * 3 = 30,000 ants

2 months from April = 30,000 * 3 = 90,000 ants

3 months from April = 90,000 * 3 = 270,000 ants

4 months from April = 270,000 * 3 = 810,000

Answer:

First, you have to set 5x equal to (3x+10). They are vertical angles and therefore congruent.

5x = 3x+10              The variable should only be on one side of the equation,

5x - 3x = 10             Therefore subtract 3x from both sides

2x = 10                     Divide by 2 on both sides.

x = 5

We're not done yet, since we've found the x-value we have to solve for ∠GEC.

∠GEC = 3x+10 = 3(5)+10 = 15+10 = 25°

∠GEC and ∠FEG form a right angle. This means that the sum of the two angles is 90°

90° = 25° + x            In this case, we're using "x" to solve for ∠FEG

90-25 = x                  We subtract 25 from both sides to get the variable by itself.

65° = x

∠FEG = 65°            The Answer is B

area of circle =  π r²

π r²= 49 π

r²= 49             r= √49                  r= 7

circumference of circle = 2 π r

                                       = 2×7 × π

                                       = 14 π

The circumference of a circle is 14π.

A circle is a two-dimensional figure with a radius and circumference of πr.

The area of a circle is πr².

We have,

Area of a circle = 49π in².

Area of a circle = πr²

Now,

πr² = 49π

r² = 49

r = 7

Now,

Circumference of a circle.

= 2πr

= 2π x 7

= 14π

Thus,

The circumference of a circle is 14π.

younger sibling = 29 years

older sibling = 35 years

Step-by-step explanation:

Let

x = younger sibling

y = older sibling

x + y = 64 (1)

The older sibling was born 6 years before their young sibling

x = y - 6 (2)

Substitute x = y - 6 into (1)

x + y = 64

y - 6 + y = 64

2y = 64 + 6

2y = 70

y = 70/2

y = 35 years

Substitute y = 35 into (2)

x = y - 6

x = 35 - 6

x = 29 years
