Answer:

[tex]\overline{GB}[/tex] = 9

Step-by-step explanation:

The given parameters are;

The point of intersection of the perpendicular bisectors of the sides [tex]\overline{BC}[/tex], [tex]\overline{BA}[/tex], and [tex]\overline{CA}[/tex] intersect (meet) at point G

Let D represent the point of intersection of the perpendicular bisector from G to [tex]\overline{BC}[/tex], we have for ΔBGD and ΔCGD;

[tex]\overline{GD}[/tex] ≅ [tex]\overline{GD}[/tex] by reflexive property

∠GDB = ∠GDC = 90° given that [tex]\overline{GD}[/tex] is the perpendicular bisector of [tex]\overline{BC}[/tex]

Similarly, [tex]\overline{DB}[/tex] ≅ [tex]\overline{DC}[/tex], also given that  [tex]\overline{GD}[/tex] is the perpendicular bisector of [tex]\overline{BC}[/tex]

Therefore;

ΔBGD ≅ ΔCGD by Side-Angle-Side (SAS) rule of congruency

[tex]\overline{GB}[/tex] ≅ [tex]\overline{GC}[/tex]   by Congruent Parts of Congruent Triangles are Congruent, (CPCTC)

[tex]\overline{GB}[/tex] = [tex]\overline{GC}[/tex] = 9 by definition of congruency

∴ [tex]\overline{GB}[/tex] = 9.

Answer:

A, and D

Step-by-step explanation:

If you go through all the problems, just replace "b" with "(4)" into a calculator. For A and D, they both equaled 180.

The expression that has a value of 180 when b = 4 is D. 51b−24

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

87b - 179 + 957/87.

= 87(4) - 179 + 857/87.

= 348 - 179 + 9.85, will not be 180.

33b12, will not be 180 at b = 4.

b² + 120,  will not be 180 at b = 4.

51b - 24.

= 51(4) - 24.

= 204 - 24.

= 180.

11b + 187 - 1756/13.

= 11(4) + 197 - 135.07, will not be 180 at b = 4.

Answer: 1.67 feet in 1 second

Step-by-step explanation: To find out how far the penguin walked in 1 second, you’ll have to divide 10 by 6 or use the ratio 10 : 6 and divide. You should get a final answer or result of 1.67 feet in 1 second.

*Tip: If you want to make sure your answer is correct, simply multiply your answer times 6, and see if it equals to 10 or is near 10.

Answer:

5/3 ft

Step-by-step explanation:

10 ft = 6s

x ft = 1s

cross multiply

10ft × 1s = 6s × x

{divide both sides by The coefficient of x (6x) }

(10 ft × s) ÷ 6s= x

10 ft ÷ 6 = x

5/3 ft = x

x = 5/3 ft

Answer:

V=22/7×r^2×h

=22/7×(5.93/2)^2×10

=276.26cm

Step-by-step explanation:

Use the equation V=22/7×r^2×h

V=volume

r=radius

h=height

Substitute the values for r and h, then find the value for V

The volume of cylinder is 276.04 cm³.

The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it. The formula πr²h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder.

Given:

d= 5.93

h= 10cm

r= 5.93/2

Now, volume of cylinder

= πr²h

= 3.14 x 5.93/2 x 5.93/2 x 10

= 31.4 x 8.7912

= 276.04 cm³

Hence, the volume of cylinder is 276.04 cm³.

Answer:

George will swim 45 laps on Monday.

Step-by-step explanation:

The number is being increased by 9 each time, starting at 18 laps on Friday; it increases by 9 laps each day.

Answer:

45 laps on Monday; start at 18 and add 9 each time.

Step-by-step explanation:

The pattern is adding 9 each time. You can see that 18, 27, and 36 are all numbers that go up every time. They are all also multiples of 9. (9*2=18, 9*3=27, 9*4=36, etc.) So, if you add 9 to 36, it equals 45, so George swims 45 laps on Monday.

Answer:

It will take 135 minutes or 2 hours and 15 minutes

Step-by-step explanation:

What we need here is to get the total

amount in pounds of turkey to be cooked

each person eats 3/8 pound servings

Total pound per person would be 3/8 * 2 = 3/4 pound servings

From what we have, there are 15 people at the dinner,

The total pounds to cook will be

15 * 3/4 = 45/4 pounds

Per pound of turkey, it takes 12 minutes

For 45/4 pounds, it will take

45/4 * 12 = 135 minutes

Let us convert this to hours

That will be 2 hours and 15 minutes

Answer:

x <4

Step by step explanation:

Answer:

I think you are asking for the price Robert paid after the 30% off. There are two ways to do this. The first way is to find 30% of the full price and substract it from the full price or we could find 70% of the full price.

Lets make x the new price.

Step-by-step explanation:

First way:

x = 79.95 - (79.95 x 0.30)

x = 79.95 - 23.985

x = 55.965

(we round to the hundredth)

x = 55.97

Second way:

x = 79.95 x 0.70

x = 55.965

(we round to the hundredth)

x = 55.97

Answer:

$525.62

$13,244.64

Step-by-step explanation:

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

Where,

A = future value = ?

P = principal = $24,600

r = interest rate = 7.2% = 0.072

n = number of periods = 12

t = time = 6 years

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

= 24,600(1 + 0.072/12)^12*6

= 24,600(1 + 0.006)^72

= 24,600(1.006)^72

= 24,600(1.5384)

= 37,844.64

12 months × 6 years = 72 months

Each monthly payment = Total payment / number of months

= $37,844.64 / 72

= $525.62

Total amount of interest = Total payment - Principal payment

= $37,844.64 - $24,600

= $13,244.64

Answer:

[tex]13x^{2}[/tex]-20x+8

Step-by-step explanation:

Step 1: rearrange the equation

16x^2 - 3x^2 - 7x - 13x +8

Step 2: solve the equation

16x^2 - 3x^2 = 13x^2

-7x - 13x = -20x

(the +8 will stay the same)

so when we put it all together it gives us

13x^2 - 20x + 8
