Explanation:

Let r be the radius we want to find

The area of the full circle is A = pi*r^2

The unshaded portion is 60 degrees, so the unshaded portion must be 360-60 = 300 degrees.

The full area was pi*r^2, but we only want 300/360 of that full area.

So,

s = shaded area

s = (300/360)*(full circle area)

s = (300/360)*(pi*r^2)

s = 30pi

(300/360)*(pi*r^2) = 30pi

(300/360)*r^2 = 30

(5/6)*r^2 = 30

5r^2 = 30*6

5r^2 = 180

r^2 = 36

r = sqrt(36)

r = 6

The radius is 6 inches.

3 months = 90 days

90/2 = 45 days of new jokes

45 days x 3 jokes per day = 135 jokes

Answer:

A: 3/5 + 2/5 = 5/5

A: 3/5 + 1/5 = 4/5

B: 3/5 - 2/5 = 1/5

B: 3/5 - 1/5 = 2/5

C: 3/5 x 2/5 = 6/25

C: 3/5 x 1/5 = 3/25

C: 2/5 x 1/5 = 2/25

D: 1/2 + 1/4 = 3/4

D: 4/5 + 4/10 = 6/5

E: 4/6 ÷ 2/6 = 2

E: 1/6 ÷ 1/6 = 1

Step-by-step explanation:

Answer:

the (x, y) pair solution to the system is: (-2, -4)

That is x = -2 and y = -4

Step-by-step explanation:

I presume there is a variable y missing in the first equation, and in fact the system looks like:

(1/2) x + (3/2) y = - 7

- 3 x + 2 y = -2

In such case, we proceed to multiply both sides of tye first equation by 6

6 (1/2) x + 6 (3/2) y = - 42

3 x + 9 y = - 42  and we add term by term this equation to the second one, so as to cancel out the term in x:

3 x + 9 y = - 42

- 3 x + 2 y = -2

_____________

11 y = - 44

divide both sides by 11 to isolate y

y = -44 / 11 = -4

Then with the value y = -4, now we replace it in the second equation to solve for x:

- 3 x + 2 y = - 2

- 3 x + 2 (- 4) = -2

- 3 x - 8 = - 2

add 8 to both sides

- 3 x = 6

divide both sides by (-3) to isolate x

x = 6 / (-3) = - 2

Therefore the (x, y) pair solution to the system is: (-2, -4)

That is x = -2 and y = -4

Step-by-step explanation: 18 feet tall is the gateway arch . The angle of elevation from a park bench 778 feet from the base of the Gateway Arch in St

Answer/Step-by-step explanation:

Given:

m<6 = 40°

Required:

Measure of all the other numbered angles

Solution:

Since line a is parallel to line b, therefore:

✔️m<1 = 180° - m<6 (supplementary angles)

m<1 = 180° - 40° (substitution)

m<1 = 140°

✔️m<2 = m<6 (corresponding angles)

m<2 = 40° (substitution)

m<3 = 180° - m<6 (same side interior angles are supplementary)

m<3 = 180° - 40° (substitution)

m<3 = 140°

✔️m<4 = m<6 (alternate interior angle)

m<4 = 40°

✔️m<5 = 180° - m<6 (linear pair)

m<5 = 180° - 40°

m<5 = 140°

✔️m<7 = m<5 (vertical angles)

m<7 = 140°

✔️m<8 = m<6 (vertical angles)

m<8 = 40°

Answer:

D, C and A

Step-by-step explanation:

Had this test so i know the answer

The triangles ΔACB and ΔDFE are congruent if ∠F is 90°. Then the correct option is D.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

The ratio of the matching sides will remain constant if two triangles are comparable to one another.

Prove that the triangles ΔACB and ΔDFE are congruent.

AB = DE (Given)

BC = EF (Given)

∠ACB = ∠DFE = 90°

The triangles ΔACB and ΔDFE are congruent if ∠F is 90°. Then the correct option is D.

Answer:400

Step-by-step explanation:it didn’t say it gives away and souvenirs so the 6$ can be out the equation and 4000 divided by 10 is 400

The number of tickets that must be sold to break even is 1000 if at a local ballpark a team charges $10 per ticket the team must pay its players $4000.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is:

At a local ballpark, a team charges $10 per ticket. The team must pay its players $4000. It costs the owners $6 for each souvenir they give away.

How many tickets must be sold to break even.

Let x be the number of tickets.

Let y be the total cost

From the data given in the question we can frame the linear equation in two variables:

y = 6x + 4000

y = 10x

After solving the above two linear equations in two variables.

6x + 4000 = 10x

10x - 6x = 4000

4x = 4000

x = 1000

Thus, the number of tickets that must be sold to break even is 1000 if at a local ballpark a team charges $10 per ticket the team must pay its players $4000.

Answer:

42/2    (the second choice down)

Step-by-step explanation:

Step-by-step explanation:

in equation 1

y=4x+12

so now

eqs 2

2y=4+3x

then

-y=x+8

y= -x-8

so

-x-8=4x+12

-20=5x

-4=x

so

y= 4-8
