3×10^9

Answer:

98%.

Step-by-step explanation:

The following data were obtained from the question:

Test 1 (T₁) = 83%

Test 2 (T₂) = 91%

Test 3 (T₃) = 88%

Test 4 (T₄) =?

AVERAGE = 90%

We can obtain the score of 4th test by doing the following:

AVERAGE = (T₁ + T₂ + T₃ + T₄) /4

90 = (83 + 91 + 88 + T₄) /4

90 = (262 + T₄) /4

Cross multiply

90 × 4 = 262 + T₄

360 = 262 + T₄

Collect like terms

360 – 262 = T₄

T₄ = 98%

Therefore, Sam need to score 98% in the 4th test in order to have an average score of 90%.

Answer:

slope = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 14, - 18) and (x₂, y₂ ) = (- 10, - 12) ← 2 ordered pairs from the table

m = [tex]\frac{-12+18}{-10+14}[/tex] = [tex]\frac{6}{4}[/tex] = [tex]\frac{3}{2}[/tex]

Answer:

The number series 1, 3, 5, 7, 9, . . . . , 59. Therefore, 900 is the sum of first 30 odd numbers.

The conjecture we can make is C. The sum is equal to the no. of terms squared.

According to the given question we have been asked What conjecture can you make about the sum of the first 33 positive odd natural numbers.

We know that the sum of first 'n' odd natural numbers is n².

So, the sum of first 33 odd natural numbers is (33)² which is = 1089.

Let us prove this by AP.

First term(a₁) is = 1.

common difference(d) = 2.

No. of terms (n) = 33.

∴ aₙ = a₁ + (n-1)d

aₙ = 1 + (33-1)2

aₙ = 1 + 32(2).

aₙ = 1 + 64.

aₙ = 65.

∴ S₃₃ = 33/2×[ 2(1) + (33-1)2].

S₃₃ = 33/2×[ 2 + 64].

S₃₃ = 33/2×66.

S₃₃ = 33×33.

S₃₃ = 1089.

Answer:

∠ A = 60°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{13}{15}[/tex] , thus

∠ A = [tex]sin^{-1}[/tex] ( [tex]\frac{13}{15}[/tex] ) ≈ 60°

------------------------------------------------

Using the cosine ratio in the right triangle

cosR = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{RT}{RS}[/tex] = [tex]\frac{8}{10}[/tex] , thus

∠ R = [tex]cos^{-1}[/tex] ( [tex]\frac{8}{10}[/tex] ) ≈ 36.9° ( to 1 dec. places )

Step-by-step explanation:

Answer:

First piece = a = 5 inches

Second piece = b = 10 inches

Third piece = c = 37 inches

Step-by-step explanation:

Let us represent:

First piece = a

Second piece = b

Third piece = c

52-inch piece of steel is cut into three pieces.

a + b + c = 52 inches

The second piece is twice as long as the first piece

= b = 2a

The third piece is two inches more than seven times the length of the first piece.

= c = 2 + 7(a)

Find the lengths of the pieces. The lengths of the first, the second, and the third pieces are in, in, and in respectively.

a + b + c = 52 inches

Substitute 2a for b

2 + 7a for c

a + 2a + 2 + 7a = 52

Collect like terms

10a = 52 - 2

10a = 50

a = 50/10

a = 5 inches.

b = 2a

b = (2 × 5)

b = 10 inches

c = 2 + 7a

= 2 + 7(5)

= 2 + 35

= 37 inches

Answer:

x = 12.48

Step-by-step explanation:

Simplifying

12(x + -13) = 13(12 + -1x)

Reorder the terms:

12(-13 + x) = 13(12 + -1x)

(-13 * 12 + x * 12) = 13(12 + -1x)

(-156 + 12x) = 13(12 + -1x)

-156 + 12x = (12 * 13 + -1x * 13)

-156 + 12x = (156 + -13x)

Solving

-156 + 12x = 156 + -13x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '13x' to each side of the equation.

-156 + 12x + 13x = 156 + -13x + 13x

Combine like terms: 12x + 13x = 25x

-156 + 25x = 156 + -13x + 13x

Combine like terms: -13x + 13x = 0

-156 + 25x = 156 + 0

-156 + 25x = 156

Add '156' to each side of the equation.

-156 + 156 + 25x = 156 + 156

Combine like terms: -156 + 156 = 0

0 + 25x = 156 + 156

25x = 156 + 156

Combine like terms: 156 + 156 = 312

25x = 312

Divide each side by '25'.

x = 12.48

Answer:

58

Step-by-step explanation:

Step-by-step explanation:

AD=DC

So angle A is equal to angle C

Let Angle A be x

And angle ABD is equal to 90 degree

So in triangle ADB

90+32+x=180 (angle sum property)

x=180-122

x=58

As angle A and angle C are equal

So angle C=58 degrees

Answer:

(i) From 0 to 50.

(ii) From 3 to 5.

(iii) From 3R to 5R, where R=3,4,5,...

Step-by-step explanation:

Let N be the number of players in a team.

As each team can have numbers of player ranging from 3 to 5, so

[tex]3\leqN\leq5\cdots(i)[/tex]

Let P be the points scored by one player in one round of the game.

As each player can score up to 10 points in each round of the game, so

[tex]0\leq P \leq 10\cdots(ii)[/tex]

(1) There are 5 members in the team formed by Elena.

So, points earned by 5 players in 1 round = 5P

From equation (ii), the range is

[tex]0\leq 5P \leq 50[/tex]

Hence, the points earned by Elena's team is ranging from 0 to 50.

(2) If each played misses 1 point, then,

Points earned by 1 player in 1 round = 10-1=9

Hence, points earned by 5 players in 1 round = 9x5=45.

(3) Let R (an integer) denoted the number of teams.

As there are at least 3 teams in the game, so

[tex]R\geq3\cdots(iii)[/tex]

As the number of players in one team is N, so

the number of players in R team is NR, where R=3,4,5,...

Now, from equation (i)

[tex]3R\leqNR\leq5R[/tex]

Hence, if there are at least 3 teams, then the number of players is ranging from 3R to 5R.

For R=3, the number of players in the game is ranging from 3x3=9 to 5x3=15.

Step-by-step explanation:

Giving the following information:

The expression 120+4x represents the cost of producing x items. The selling price is $5 for each item.

The net income formula:

y= (5 - 4)x - 120

(5-4)= contribution margin per unit sold (x)

120= fixed costs

To calculate the break-even point in units, we need to use the following formula:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 120 / 1

Break-even point in units= 120 units

Prove:

y= 1*120 - 120

y= 0

If the balance is growing exponentially the balance after 45.4 months will be $44,925.94.

Step-by-step explanation:

[tex]f(x)=700(1+0.096)^{x}[/tex]

Compute the value of f (x) for x = 45.4 as follows:

[tex]f(x)=700(1+0.096)^{x}[/tex]

       [tex]=700(1+0.096)^{45.4}\\\\=700\times (1.096)^{45.4}\\\\=700\times 64.1799181\\\\=44925.94267\\\\\approx 44925.94[/tex]

Thus, if the balance is growing exponentially the balance after 45.4 months will be $44,925.94.

The point of collision is θ = π/6.

A curve's polar equation is often stated with r as a function of θ and represented in polar coordinates.

The given equations are r = √3 + 2cosθ and r = 4cosθ.

The characters will collide at the intersection of these paths, the intersection of the two equations is given by:

√3 + 2cosθ = 4cosθ

4cosθ - 2cosθ = √3

2cosθ = √3

cosθ = √3/2

θ = cos⁻¹(√3/2)

θ = π/6

Hence, the point of collision is θ = π/6.
