Answers

Answer:

44.2545

Step-by-step explanation:

you can find the third angle by taking 180-(90+55)=a

a=35

use law of sines

Sin(angle)/(opposite side of angle)=Sin(another angle)/(opposite side of another angle)

so, sin(a)/A=sin(b)/B

sin(35)/33=sin(55)/x

x=sin(55)/(sin(35)/33)

x=44.2545

Step-by-step explanation:

if a - b = 4 and a² - b² =12, what is the value of a + b?.

help.​

Answers

Answer:

a² - b² = ± 32

Step-by-step explanation:

⇒ a + b = 4

⇒ a = 4 - b   ... ( 1 )

Substituting this in another equation we get,

⇒ ab = -12

⇒ ( 4 - b ) ( b ) = -12

⇒ 4b - b² = -12

⇒ b² - 4b - 12 = 0

⇒ b² - 6b + 2b - 12 = 0

⇒ b ( b - 6 ) + 2 ( b - 6 ) = 0

⇒ ( b + 2 ) ( b - 6 ) = 0

⇒ b = -2, 6

Case 1: If b = -2

⇒ a = 4 - b

⇒ 4 - ( -2 ) = 4 + 2 = 6

Case 2: If b = 6

⇒ a = 4 - b = 4 - 6 = -2

Hence the numbers are 6 and -2.

⇒ a² - b² = ?

Case 1: a = 6 and b = -2

⇒ ( 6 )² - ( -2 )²

⇒ 36 - 4 = 32

Case 2: a = -2, b = 6

⇒ ( -2 )² - ( 6 )²

⇒ 4 - 36 = -32

Hence the answer for a² - b² can be ± 32 depending on the values of a and b.

hope it help a little bit.

Find another point in the pattern that passes through the points (0, 2) and (2, 16)

Answers

9514 1404 393

Answer:

  (4, 30)

Step-by-step explanation:

The two points in the pattern that are given here differ by 2 in their x-value and by 14 in their y-value. Another point can be found by adding 2 more to x and 14 more to y:

  (2, 16) +(2, 14) = (4, 30)

(Y2-Y1)/ (X2-X1) = slope

What is the slope-intercept form?

y= Mx+b. M= slope B= y-int.

(10-2) / (6-4) = 8/2

Slope=4

A tower is topped by a right circular cone with a diameter of 24 feet and a height of 36 feet. The space inside the cone is used for housing electronic equipment.
361

Answers

Answer:

the answer is (5426)

Step-by-step explanation:

i got the answer online

The space inside the cone is 5426 cubic feet

What is the volume of a cone?

The formula for the volume of a cone is V = ( 1 / 3 ) πr²h.  

Given data ,

Diameter of cone = 24 ft

Radius of cone = ( Diameter of cone / 2 ) = 12 ft

Height of cone = 36 ft

Space inside the cone = Volume of cone

Volume of Cone = ( 1 / 3 ) πr²h

                           = ( 1 / 3 ) x ( 22 / 7 ) x 12 x 12 x 36

                           = ( 22 / 7 ) x 48 x 36

                           = ( 22 / 7 ) x 1728

                           ≈ 5426 cubic feet

Hence , the space inside the cone is 5426 cubic feet

Jackson School is doing a fundraiser selling magazine subscriptions. The magazine publisher will pay the school a starting bonus of $500 and then $4 for each subscription sold. At the end of the fundraiser, the school is paid a total of $1360. How many subscriptions did they sell?

Answers

Answer: 215 subscriptions

Step-by-step explanation:

First, remove the starting bonus of $500 to find out the amount that was acquired from subscription sales:

= 1,360 - 500

= $860

The school is paid $4 for every subscription and they made $860 from this. The total number of subscription was therefore:

= 860 / 4

= 215 subscriptions
