1/2 × (30×4) × 39 + (30×30)

= 60 × 39 + 900

= 2340 + 900

= 3240

Answer:

x = 39

Step-by-step explanation:

all triangles have angle measures that add up to 180°.

This means that to find what x is, you add 102 and 39, and then subtract that from 180, so

180-(102+39) = x

180-141=x

39=x

Answer:

x° = 39°

Step-by-step explanation:

According to the angle sum property of triangles, the 3 angles in a triangle will sum up to 180°.

102° + 39° + x° = 180°

141° + x° = 180°

x° = 180° - 141°

x° = 39°

1In unit 10 circles homework 9 standard form of a circle in all things' algebra, the center is (0,-2) and radius is 8 units.

The equation of the circle is the equation which is used to represent the circle in the algebraic equation form, with the value of center point in the coordinate plane and measure of radius.

The standard form of the equation of the circle can be given as,

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Here (h,k) is the center of the circle and (r) is the radius of the circle.

For the first problem,

[tex]x^2+(y+2)^2=64[/tex]

Rewrite the equation to make it the equation of circle as,

[tex](x-0)^2+(y-(-2))^2=8^2[/tex]

Compare it with equation of circle, we get center at (0,-2) and radius of 8 units. Similarly, the center and radius for each of the equation can be found out.

Thus, in unit 10 circles homework 9 standard form of a circle in all things' algebra, the center is (0,-2) and radius is 8 units.

Answer:

6×pi ft

Step-by-step explanation:

the area of a circle is

pi × r²

with r being the radius of the circle.

so,

9×pi = r² × pi

9 = r²

r = 3 ft

the circumference of a circle is

2×pi× r

that means in our case it is

2×pi×3 = 6×pi ft

Answer:

The probability that a student from this class eats breakfast but does not floss their teeth is .11 (11%).

Step-by-step explanation:

Let's start by making a two-way table (you can also make a tree diagram).

Let's make the total number of students = 100. Now, fill out the table using the given probabilities from the question.

We are given that 57% of students eat breakfast in the morning, so the total in the "Eats breakfast" column is 57.

80% of the students floss their teeth, so the total in the "Flosses teeth" row is 80.

We can fill out the rest of the table using simple algebra and the fact that the probabilities must add up to 1.

I've attached a table that I created showing what the two-way table should look like when filled out completely.

Now, we want to find the probability that a student eats breakfast but does not floss their teeth.

We can look at the column "Eats breakfast" and the row "Does not floss teeth" and see that 11 (out of 100) students eat breakfast without flossing their teeth.

Therefore, the probability that a student from this class eats breakfast without flossing their teeth is .11.

Answer:

x = 19/2

Step-by-step explanation:

1) Distribute

-8x-24=-10x-5

2) Add 24 to both sides

-8x-24+24=-10x-5+24

3) Simplify

- Add the numbers

-8x = -10x - 5 + 24

- Add the numbers

-8x = -10x+19

4) Add 10x to both sides

-8x+10x=-10x+19+10x

5) Simplify

- Combine like terms

2x = -10x+19+10x

-Combine like terms

2x=19

6) Divide both sides by the same factor

2x/2 = 19/2

7) Simplify

- Cancel terms that are in both the numerator and denominator

x = 19/2

Answer:

what is intercept: intercept simply means a point on the y axis through which a slope passes and also in the equation you were given y = mx + c I mean y = 2x -2 the c is the intercept meaning -2 .

so wherever that straight line meets with with y axis the number at that very point is your intercept.

the y intercept for the first one is -2

and it's "less than" since it's a negative number.

The division is one of the four fundamental arithmetic operations. The rent of the flat for each month will be Rs. 30,000.

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that the rent of the flat for one year is Rs. 3,60,000. Since a year has 12 months. Therefore, the rent for each month will be,

[tex]\rm \text{Rent for one month} = \dfrac{Rs.\ 3,60,000}{12} = Rs.\ 30,000[/tex]

The equation can be used to solve for the measure of angle abc is sinx = 2.4/10.3

The identity is used to find the measure of sides and acute angles of a right triangle

From the diagram shown, <ABC is the reference abgle hence;

Opposite side = 2,4cm

Hypotenuse .=10.3cm

According to the identity

sin x = opp/hyp

sinx = 2.4/10.3
sinx = 0.233

x =  13.47 degrees

Hence the equation can be used to solve for the measure of angle abc is sinx = 2.4/10.3

Answer:

False.

Step-by-step explanation:

What is the question if you have the solution already?

I guess its a true/false question. In that case it's false because:

-x + 10 = 2x + 4

-x -2x + 10 = 4

-x - 2x = 4 - 10

-3x = -6

x = - 6 / -3

x = 2

Answer:

False.

This equation has only one solution, and it is x = 2.

Step-by-step explanation:

-x + 10 = 2x + 4

Subtract 2x from both sides.

-3x + 10 = 4

Subtract 10 from both sides.

-3x = -6

Divide both sides by -3.

x = 2

False.
