Answer:

Step-by-step explanation:

a+b=58 and 4a-2b=28 is the system of equations

solving the first for a, a=58-b, using this value for b in second equation is

4(58-b)-2b=28

232-4b-2b=28

232-6b=28

-6b=-204

b=34, and since a=58-b

a=58-34

a=24

So the two numbers are 24 and 34

Perpendicular bisector theorem

Step-by-step explanation:

The illustration of the theorem is:

If point B is a perpendicular bisector of Line AC and the length of AC is 10cm

Then

[tex]AB + BC = 10[/tex]

Where

[tex]AB = BC[/tex] --- Perpendicular bisector

So, the equation becomes

[tex]AB + AB =10[/tex]

[tex]2AB =10[/tex]

[tex]AB = 5[/tex]

Recall: [tex]AB = BC[/tex]

[tex]AB = BC = 5[/tex]

A trapezoid consists of two triangles.

A trapezoid does indeed contain two triangles within its structure. A trapezoid is a quadrilateral with one pair of parallel sides.

The other two sides, known as the legs, are not parallel and meet at a point. These legs, along with the two parallel sides, form two triangles within the trapezoid.

One triangle is formed by connecting the two legs and one of the parallel sides. The other triangle is formed by connecting the two legs and the other parallel side.

So, a trapezoid consists of two triangles.

Answer:

32° and 116°

Step-by-step explanation:

An isosceles triangle has two equal angles and the other angle is found by subtracting the sum of the two equivalent angles from 180°.

Since, one of the angles are given in the problem, one of the angles is 32°.

To find the other angle, we subtract the two angles from 180°.

180° - 32° - 32°

116°

The other two angles are: 32° and 116°

Step-by-step explanation:

(f-g)(x) = f(x) - g(x)

or we can also do

(f-g)(x) = 5x - |x + 7|

f(2) = 5*2 = 10

g(2) = |2 + 7| = |9| = 9

(f-g)(2) = f(2) - g(2) = 1

Answer:

you will have an 18% chance of rolling a 2.

Step-by-step explanation:

18/100 = 18

The probability of spinning an even number is 39/10

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Here, we have,

to determine the probability of spinning an even number.

The missing bar chart is added as an attachment

The bar chart (see attachment) represents the graph that would be used to calculate the required probability

On the bar chart, we have the sample size of the even number

Even number = 18 + 21

Even number = 39

So, we have

P(Even) = Even/Total

By substitution. we have

P(Even) = 39/100

Hence, the probability is 39/100

Answer:

1.77 ft.^2

Step-by-step explanation:

What we know: diameter of circle is 1.5

What we need: the radius to find the area of a circle

What we can do: Divide 1.5 by two to get the radius(since the diameter is twice the radius : radius x 2 = diameter)

Math -->  1.5 divide by 2 = .75

What we need to know: Formula of finding Area of Circle is  A=(pie)r^2

Insert what we know: A=(pie).75^2

Work out problem(do radius to the second power first)#1:  .75^2 =  .5625(unrounded)

Work out problem(multiply number by pie))#2: .5625 multiplied by (pie) = 1.7671458676442586966352369030947‬

Round Answer to nearest hundredth: 1.77 ft.

Note: I use the pie sign for this problem. So I used : 3.1415926535897932384626433832795‬

I used a scientific calculator for the calculations.

^2 is added after the unit to show Area.

To the second power  is multiplying the number by itself. Example: 4^2 = 16 = 4 x 4
