Answer:

900

Step-by-step explanation:

1.analyze problem

2. 30/13*390

3.900

Answer:

x = 29°, y = 61°

Step-by-step explanation:

x + 61 = 90

Because of the right angle symbol

x = 90 - 61

x = 29°

x + y = 90

Because vertically opposite angles are equal

29 + y = 90

y = 90 - 29

y = 61°

Answer: m<D = 30

Step-by-step explanation: In the third step of the problem, it says that E is next to itself and equals 90. However, this is not true. Angle BEA and angle CED are vertical angles and are both equal to 65°. This means that to find the measurement of angle D, subtract 65 and 85 from 180, which equals 30.

Answer:

= (y - 4x) (y - 7)

Step-by-step explanation:

y^2-4xy-7y+28x

--

factor out y from y^2 - 4x : y(y - 4x)

factor out 7 from 28x - 7y : 7(4x - y)

= y (y - 4x) + 7(4x - y)

7 (4x - y) + 7(y - 4x)

= y (y - 4x) - 7(y - 4x)

= (y - 4x) (y - 7)

Answer:

85 points

Step-by-step explanation:

His total points will be 235+x

Number of tests will be 4

(235+x)/4 = 80

multiply by 4

235+x= 4*80

235+x= 320

x=320-235

x= 85

He has to get 85 points to average 80

Answer:

942ft^2

Step-by-step explanation:

Use the equation (θ/360)*[tex]\pi[/tex][tex]r^{2}[/tex] to get the area of the shaded sector.

(120/360)*[tex]\pi[/tex]*[tex]30^{2}[/tex]

(1/3)*[tex]\pi[/tex]*900

≈942[tex]ft^{2}[/tex]

The area of the shaded region is 942 square ft if the radius of the circle is 30 ft option (G) is correct.

It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)

We have a circle shown in the picture.

The area of the shaded region:

[tex]\rm A = \dfrac{120}{360}\pi (30)^2[/tex]

A = 942.47 ≈ 942 square ft

Thus, the area of the shaded region is 942 square ft if the radius of the circle is 30 ft option (G) is correct.

Answer:

B

Step-by-step explanation:

The Law of Sines states that

sinA/a = sinB/b = sinC/c

We know A, a, and b. Given this, we can solve for B, and given that, we can solve for C and then c.

First, we solve for B.

sinA/a = sinB/b

sin(15°)/6 = sinB/8

sin(15°)/6 * 8 = sinB

arcsin(sin(15°)/6 * 8) = B ≈ 20.187

Note that there can be a second B value. We can check if there is a second B value by first subtracting the B value we got from 180.

180 - 20.187 = 159.813

Next, we can add that to our existing angle, A = 15°. If that is less than 180, then we do have a second solution. 159.813 + 15 = 174.813 < 180 so there does exist a second solution where B = 159.813

Next, we can solve for C.

We know that the angles in a triangle add to 180°, so A + B + C = 180. Therefore, for the first solution:

15 + 20.187 + C = 180

C = 180 - 15 - 20.187 = 144.813°

and for the second:

15 + 159.813 + C = 180

C = 180 - 15 - 159.813 = 5.187

Finally,

sinA/a = sinC/c

multiply both sides by c to no longer have it as a denominator

sinA * c / a = sinC

divide both sides by (sinA/a) to isolate c

for the first solution:

c = sinC*a/sinA = 13.35868 ≈ 13.36

and for the second:

c = sinC*a/sinA ≈ 2.10

Answer:

Number of the houses as x =35

Step-by-step explanation:

The number of houses is 1, 2, 3, ..., 49

By observation, the numbers of houses are in an A.P.

Hence

First-term, a = 1

Common difference, d = 1

Let us assume that the number of xth house can be expressed as below:

We know that sum of n terms in an A.P. is given by the formula Sₙ = n/2 [2a + (n - 1) d]

Sum of number of houses preceding xth house = Sₓ ₋ ₁

Sₓ ₋ ₁ = (x - 1) / 2 [2a + ((x - 1) - 1)d]

= (x - 1) / 2 [2 × 1 + ( x - 2) × 1]

= (x - 1) / 2 [2 + x - 2]

= [x (x - 1)] / 2 ---------- (1)

By the given information we know that, sum of number of houses following xth house = S₄₉ - Sₓ

S₄₉ - Sₓ = 49 / 2 [2 × 1 + (49 - 1) × 1] - x / 2 [2 × 1 + (x - 1) × 1]

= 49 / 2 [2 + 48] - x / 2 (2 + x - 1)

= (49 / 2) × 50 - (x / 2) (x + 1)

= 1225 - [x (x + 1)] / 2 ---------- (2)

It is given that these sums are equal, that is equation (1) = equation(2)

x (x - 1) / 2 = 1225 - x (x + 1) / 2

x² / 2 - x / 2 = 1225 - x² / 2 - x / 2

On solving further we get,

x² = 1225

x = ± 35

As the number of houses cannot be a negative number, we consider the number of houses as x = 35

35 is the correct answer

Step-by-step explanation:

Given that the houses in a row are numbered consecutively from 1 to 49. We need to show that there exists a value of x such that the sum of numbers of houses preceding the house numbered x is equal to sum of the number of houses following x. Making it more simple for you; sum of (1, 2, 3, 4.... upto x - 1) is equal to sum of (x + 1), (x + 2), (x + 3).... upto 49.

→ Sum of (x - 1) terms = Sum of (49 - x) terms

"x" is the number of houses required. The sum of houses are in AP where the value of a is 1 and d is also 1; where 'a' is first term and 'd' is common difference. We know that sum of nth term of an AP is given by: T(n) = a + (n - 1)d and upto nth term by S(n) = n/2 (2a + (n - 1)d). And also by T(n) = S(n) - S(n - 1).

As per given problem:

→ (x - 1)/2 (Sum of first and last term) = (49 - x)/2 (Sum of first and last term)

→ (x - 1)(Sum of first and last term) = (49 - x) (Sum of first and last term)

Where first term and last term in LHS is 1 and (x - 1) & in RHS is (x + 1) and 49. Substitute them.

→ (x - 1) (1 + (x - 1)) = (49 - x) ((x + 1) + 49)

→ (x - 1) (1 + x - 1) = (49 - x) (x + 1 + 49)

→ (x - 1) (x) = (49 - x) (x + 50)

→ x² - x = 49x + 2450 - x² - 50x

On solving we get,

→ 2x² - 2450 = 0

→ 2x² = 2450

→ x² = 1225

→ x = ± 35

The number of houses is a positive integer. So negative value neglected. We left with x = 35. Therefore, the value of x is 35.
