Answer:

7.5

Step-by-step explanation:

Using similar triangles.

Answer:

ED=7.5

Step-by-step explanation:

ΔABC is similar to ΔDEB (they share ∠B, and ∠C=∠D and ∠A=∠E because corresponding angles), so their sides are in ratio:

ED/AC=BD/BC

We can see that BC is twice BD (marked), so we know BD/BC=0.5

ED/AC=BD/BC

ED/15=0.5

ED=7.5

The explicit formula for a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = - 1 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{-5}{-1}[/tex] = 5 , then

[tex]a_{n}[/tex] = - [tex]5^{n-1}[/tex]

13

Using the explicit formula for a geometric sequence

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = - 48 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{96}{-48}[/tex] = - 2 , then

a₁₀ = - 48 × [tex](-2)^{9}[/tex] = - 48 × - 512 = 24576

or,x^2-4x-2x+8+3x^2-9x-11x+33/x^2-4x-3x+12=(4x+13)/(x+1)

or,4x^2-4x-2x-9x-11x+8+33/x^2-7x+12=(4x+13)/(x+1)

or,4x^2-26x+41/x^2-7x+12=(4x+13)/(x+1)

or, (x+1)(4x^2-26x+41)=(4x+13)(x^2-7x+12)

or,4x^3-26x^2+41x+4x^2-26x+41=4x^3-28x^2+48x+13x^2-91x+156

or,7x^2-(35+23)x+115=0

or,7x^2-35x-23x+115=0

or,7x (x-5)-23 (x-5)=0

or, (x-5)(7x-23)=0

Either, Or,

or,x=0+5 or,7x=23

:x=5 :x=23/7

Hence,x=5 or 23/7

Answer:

24 gallons

Step-by-step explanation:

"Mia has filled 3/4 (three quarters) of the fish tank with water.  How many gallons has she put in the tank to fill it 3/4 full?  Let g be the number of gallons.  Then:

(3/4)(32 gallons) = number of gallons Mia put into the tank:  24 gallons

Answer:

h = 20 mm

Step-by-step explanation:

V = πr²h

3920π = π(14²)h = π196h

divide both sides of the equation by π196:

20 = h

Answer:almonds: 10.20

Cashews :12:40

Step-by-step explanation:

The cost per pound of almonds and cashews are 10.20 and 12:40, respectively

From the complete question, we have the following equations

6a + c = 73.6

4a + 3c = 78

Make c the subject in 6a + c = 73.6

c = 73.6 - 6a

Substitute c = 73.6 - 6a in 4a + 3c = 78

4a + 3(73.6 - 6a) = 78

Open the bracket

4a + 220.8 - 18a = 78

Evaluate the like terms

14a = 142.8

Divide by 14

a = 10.20

Substitute a = 10.20 in c = 73.6 - 6a

c = 73.6 - 6 * 10.2

Evaluate

c = 12.4

Hence, the cost per pound of almonds and cashews are 10.20 and 12:40, respectively

Law of sines

Step-by-step explanation:

i took the test

The law of sines can be used to calculate the side h. Hence, option B is correct.

The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.

For triangle FGH, angles F and G are known, as is the length of side h. The sin angle is the ratio of the perpendicular to the hypotenuse we can calculate one side by using the sine angle.

Hence, Hence, option B is correct.

Answer:

67

Step-by-step explanation:

There are 65 seats in row 20, option D is correct.

Given that number of seats in row 3 are 31.

Number of seats in row 6 are 37

We need to find the rate of increase, we can calculate the difference in the number of seats between row 6 and row 3 and divide it by the number of rows in between:

Rate of increase = (Number of seats in row 6 - Number of seats in row 3) / (6 - 3)

Rate of increase = (37 - 31) / (6 - 3)

Rate of increase = 2

So, the number of seats increases by 2 seats per row.

To find the number of seats in row 20, we can use the rate of increase:

Number of seats in row 20 = Number of seats in row 3 + (Rate of increase × (20 - 3))

Number of seats in row 20 = 31 + (2× (20 - 3))

= 31 + (2 × 17)

= 31 + 34

= 65

Therefore, there are 65 seats in row 20.
