Please can someone help??!!!

===========================================================

Explanation:

Consider triangle ABC. The vertex points are at A,B,C. These represent the three cities in which the three different daughters live. Constructing the circumcenter will produce a circle such that all three points A,B,C are on that circle. Let's say that D is the center of that circle.

This means that AD, BD, CD are all radii of this same circle. Radii of the same circle are the same length, which is why point D is equally distant from A,B,C. If the mother lives at point D, then she will travel the same distance to visit any three of her daughters. See the note below.

To construct the circumcenter, we form perpendicular bisectors to segments AB, BC and AC. Technically you only need two of them. All three of these perpendicular bisectors intersect at point D.

Note: Keep in mind that roads aren't completely straight, so that means we'll have to factor in the curvature of each road. But to keep things simple, we assume each road is a straight line segment.

Answer:

18°

Step-by-step explanation:

A ski slope is 320 yards long with a vertical drop of 100 yards. Find the

angle of elevation of the ski run. Round to the nearest degree.

The formula for angle of elevation is given as:

sin θ =Opposite/ Hypotenuse

Opposite = Vertical drop = 100 yards

Hypotenuse = Ski slope = 320 yards.

Angle of elevation =

sin θ = 100/320

sin θ = 0.3125

θ = arc sin(0.3125)

= 18.209956864°

Approximately = 18°

Answer

9 - 2x

Step-by-step explanation:

since there is no equal symbol in this equation, you can only simplify it.

[tex]20-2x-11[/tex]

first combine like terms:

[tex](20-11)-2x[/tex]

then subtract 11 from 20, this will give you 20-2x-11 in its simplest form.

[tex]9 - 2x\\[/tex]

Apply the distributive property. 5 (2x) +5 (−3y) + 5 ⋅ 4

Multiply 2 by 5

10x + 5 ( − 3y ) + 5 ⋅ 4

Multiply  −3 by 5     10x − 15y + 5 ⋅ 4

Multiply  5 by 4

Answer: 10x −15y + 20

Tip: The sign   "⋅"  means multiply

Answer:

A=73

Step-by-step explanation:

sum of interior angles is (n-2)*180

5 sides, so (5-2)*180 = 3x180=540

sum of current interior angles (118+96+115+104)=433

subtract 540-433=107

This is NOT "A", this is your final interior measurement.

To get "A", take 180-107=73

A=73 degrees

Answer:

Range = 5 - 29

Step-by-step explanation:

a + b > c

a+c > b

c+b > a  

so

17+ 12 > c  ,,,,,,,,,,,,,,,,,,,,,,,,,,,, so it should be lesser than 17+12 which is 29

17 +c > 12    ,,,,,,,,,,,,,,,,,,,,,,,,, and it should be greater than 17- 12 = 5  

c+12 > 17 ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, same here,  it should be greater than 17- 12 = 5  

So the range is ,

17 + 12

to

17-12

whcih is -   (5 to 29)

Answer:

6.48 dollars total,

Step-by-step explanation:

First, you would want to multiply the amount of money per pound, by the amount of pounds. 1.60 multiplied by 4 1/2 or 4.5, would equal to 7.2 dollars. In order to find 10% of 7.2, your would need to multiply 7.2 by 0.10, which would give you 0.72. Then you would subtract 7.2 by 0.72 to get 6.48. So your answer would be 6.48 dollars. Hoped this helped.

Answer:

16

Step-by-step explanation:

There are 2 different ways to solve this

1) The bigger triangle is 4 times bigger than the smaller one

5 x 4 = 20

3 x 4 = 12

From this method you can see they all connect so you take the smaller triangles value of 4 and multiply it by 4

4 x 4 = 16

2) Pythagorean theorem and reorganizing the formula so that the a value is found

[tex]a = \sqrt{c^{2} -b^{2} }[/tex]

Answer:

1. D) 0.113

2 C) 11

Step-by-step explanation:

1. #males that chose super strength/total males

  [tex]\frac{25}{222}[/tex]= 0.113

2. the relative frequency can be converted to a percent which is 11.3%

   given that a percent is out of 100, the expected number would be 11

Answer:

13.64

Step-by-step explanation:

it's because it's basically the same size as 12.3 but a bit bigger. it cant be 18.2 because that would be too big and it cant be 6.4 cause its too small and so is 10.79.

Answer:

1/2 yard of ribbon

Step-by-step explanation:

Janice used 1/3 yard of ribbon to tie a package and 1/6 yard of ribbon to tie a bow. How many yards of ribbon did Janice use?

The number of yards that Janice used is calculated as:

1/3 yard + 1/6 yard

Lowest Common Denominator = 6

2 + 1/6

= 3/6

= 1/2 yard of ribbon

Janice used 1/2 yard of ribbon

Step-by-step explanation:

Answer: Gavin gets $99

Step-by-step explanation:

Step 1

LET amount  gotten by Jim be =x

amount  gotten by Gavin be = 3x

amount  gotten by Henry  be = 2  x 3x = 6x

Such that the total amount shared by the three of them can  be expressed as

x+ 3x + 6x = 330

Step 2

x+ 3x + 6x = 330

10x= 330

x= 330/10

x = 33

Jim gets $33

Gavin gets 3x= 3x 33= $99

Henry gets 6x= 6x 33= $198

Answer:

2.08secs

Step-by-step explanation:

Given the equation modeled by the height as h=-121t^2 +504t

The velocity of the object at the max height is zero, hence;

v = dh/dt = 0

dh/dt = -2(121)t + 504

dh/dt = -242t + 504

0 = -242t + 504

242t = 504

t = 504/242

t = 2.08secs

Hence the projectile reaches its maximum height after 2.08secs

Answer:

[tex]HE=17[/tex] units.

Step-by-step explanation:

In a triangle, centroid is the intersecting point of the medians.

Centroid divides each of the medians in ratio [tex]2:1[/tex]

So,

[tex]\frac{DH}{HE}=\frac{2}{1} \\\\\frac{DH}{HE}+1=\frac{2}{1}+1\\\\ \frac{DH+HE}{HE} =3\\\\\frac{DE}{HE}=3[/tex]

Put [tex]DE=51[/tex] units

[tex]\frac{51}{HE}=3\\\\HE=\frac{51}{3}[/tex]

[tex]HE=17[/tex] units.
