Answer:

∠ BAC = 28.5°

Step-by-step explanation:

∠ AOB = 180° - 57° = 123° ( straight angle )

OA and OB are congruent ( radii of the circle ) , then Δ AOB is isosceles with base angles congruent, that is

∠ BAC = ∠ ABO , then

∠ BAC = [tex]\frac{180-123}{2}[/tex] = [tex]\frac{57}{2}[/tex] = 28.5°

OLA WILL RUN 2 MILES THIS IS CORRECT OR RIGHT I THINK

A fraction is a way to describe a part of a whole. The total distance of the route Ola will run is 3(5/8) miles.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

A mixed fraction is a fraction that contains a whole number and a fraction whose denominator is greater than the numerator.

Given the distance from the house to the park is 1(1/4) miles, while the distance from the park to the house is 2(3/8) miles, therefore, the total distance which the ola will travel can be written as,

[tex]\rm Distance = 1\dfrac14 + 2\dfrac38\\\\Distance = \dfrac{(4 \times1)+1}4 + \dfrac{(8 \times 2)+3}{8}\\\\Distance = \dfrac54 + \dfrac{19}{8}\\\\Distance = \dfrac{5\times 2}{4 \times 2} + \dfrac{19}{8}\\\\Distance = \dfrac{10}{8} + \dfrac{19}{8}[/tex]

[tex]\rm Distance = \dfrac{10+19}{8}\\\\Distance = \dfrac{29}{8} = 3\dfrac{5}{8}\ miles[/tex]

Hence, the total distance of the route Ola will run is 3(5/8) miles.

Answer:

5.2

Step-by-step explanation:

[tex]\frac{17}{13} = \frac{x}{4}[/tex]

To solve for x, we want to isolate x. To do this, we need to multiply both sides by 4.

[tex](\frac{4}{1})(\frac{17}{13}) = x[/tex]

Multiply the numerators and the denominators separately.

4 • 17 = 68

1 • 13 = 13

[tex]\frac{68}{13} = x[/tex]

Divide.

68 ÷ 13 = 5.23

Round to the nearest tenth.

5.2

Hope this helps!

Answer:

5.2

Step-by-step explanation:

Note the equal sign. This means that these two fractions are proportional. First, find common denominators. Note that what you do to the denominator, you do to the numerator:

[tex]4 * 13 * (\frac{17}{13}) = (\frac{x}{4}) * 4 * 13\\\\4 * 17 = x * 13\\\\68 = x * 13[/tex]

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 13 from both sides:

[tex]68 = x * 13\\\\(68)/13 = (x * 13)/13\\x = 68/13\\x = 5.2[/tex](rounded to the nearest tenth).

5.2 is your answer.

Answer:

answer is unidentified 50/0

Step-by-step explanation:

Answer:

Step-by-step explanation:

the area of the squared is 5 * 5 = 25

the area of the triangle is 1/2*base*height = 1/2*2*5= 5

the area of the circle is  [tex]\pi[/tex][tex]r^{2}[/tex] = [tex]\pi[/tex][tex]2.5^{2}[/tex] = 19.625

now add the pieces up for the total

25+5+19.625 = 49.625 [tex]in^{2}[/tex]

:)

First, find the area of the semi-circle.

A= pi*radius squared

Find your radius. The diameter is 5, half of that is 2.5

Input into the formula

A= pi*2.5^2

  =3.14*6.25

  =19.625 in^2

You can round that to about 19.6 inches.

Find the area of the square

A=s^2

 = 5^2

 = 25 in^2

Find the area of the triangle.

A= b*h/2

 = 2*5/2

 = 10/2

 = 5 in^2

Add it all up.

19.6+ 25 + 5= 49.6

∴ 49.6 in²

Solution:

We have,

[tex]\log_{(x-2)}(x^2-4x-6)=\dfrac{4}{5}[/tex]

According to property of logarithm,

[tex]\log_ax=b\Leftrightarrow x=a^b[/tex]

Using the property of logarithm, we get

Step-by-step explanation:

Answer:

Width of the rectangle = 6.325 units

Length of the rectangle = 12.65 units

Side length of the square the 6.325 units.

Step-by-step explanation:

The length of a rectangle is twice the width. The area of the rectangle is 80 square units.

The area of the rectangle = Length × Width

Length = 2W

80 square units = 2W × W

80 = 2W²

W² = 80/2

W² = 40

W = √40

Width of the rectangle = 6.3245553203 units

Approximately = 6.325 units

Length = 2 × Width

= 2 × 6.325

= 12.65 units

• Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each​ square?

We you divide a rectangle into 2 squares,

The length is divided into two.

Hence, the length of the rectangle = 12.65 units

12.65 units ÷ 2 = 6.325 units.

Hence, the side length of the square the 6.325 units.

The length and width of the rectangle are 13.26 units and 6.63 units if the length of a rectangle is twice the width.

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is given that:

The length of a rectangle is twice the width. The area of rectangle 88 is square units.

As we know:

The area of the rectangle = Length×Width

L = 2W

88  = 2W × W

88 = 2W²

W² = 44

W = √44 = 6.63 units

L = 2 × Width

= 2×6.63

= 13.26 units

Thus, the length and width of the rectangle are 13.26 units and 6.63 units if the length of a rectangle is twice the width.

Step-by-step explanation:

Given the table:

Month              f(x) = Number of imports    g(x) = Number of exports

January (1)                3                                                1

February (2)             4                                                3

March (3)                  5                                                5

April (4)                     6                                                7

From the table, it is clear that:

Number of imports = number of month + 2

so

also

Number of exports  = 2(number of month) + 1

so

Therefore, the number of imports equals the number of months plus one. i.e., which is a linear function.

If we compare it with the slope-intercept form of the line

Then,

slope = m = 1

y-intercept = 2

Also number of exports equals is also a linear function.

i.e.  

Here,

slope = m = 2

y-intercept = -1

If there is some point that is equal in both the function then it can be said that they are intersecting.
