Answer:

[tex]BAC = 276[/tex]

Step-by-step explanation:

Given

See attachment

Required

Find BAC

The sum of [tex]angles\ at\ a\ point[/tex] is 360.

So:

[tex]7n + 12 + 13n - 16 + 6n = 360[/tex]

Collect like terms

[tex]7n + 13n + 6n = 360 + 16 - 12[/tex]

[tex]26n = 364[/tex]

Solve for n

[tex]n = 364/26[/tex]

[tex]n = 14[/tex]

From the circle:

[tex]BAC = 7n + 12 + 13n - 16[/tex]

Substitute 14 for n

[tex]BAC = 7*14 + 12 + 13*14 - 16[/tex]

[tex]BAC = 276[/tex]

Answer:

B. 1 1/4+5 5/6=7 1/12

Step-by-step explanation:

Gretchen rode her snowmobile 1 1/4 miles to a snowmobile trail. She rode on the trail for 5 5/6 miles and then rode back home. Which addition sentence shows how many miles Gretchen rode in all?

This is calculated as:

1 1/4 miles + 5 5/6 miles

1 + 5 + ( 1/4 + 5/6)

Lowest common denominator = 12

6 + ( 3 + 10/12)

6 + 13/12

6 + 1 1/12

7 1/12

Step-by-step explanation:

The Titanic could stay afloat with four of its 16 watertight compartments flooded, more than anyone could imagine on a ship of its size. ... As the ice bumped along its starboard side, it punched holes in the ship's steel plates, flooding six compartments. In a little over two hours, the Titanic filled with water and sank.

Answer:

630 is the LCM

Step-by-step explanation:

Prime factorization of the numbers:

30 = 2 × 3 × 5

90 = 2 × 3 × 3 × 5

315 = 3 × 3 × 5 × 7

LCM(30, 90, 315)

= 2 × 3 × 3 × 5 × 7

= 630

hope this helps :)

Answer:B

Step-by-step explanation: y=x+2

Answer:

Is dis a question...??????

Answer:

(x - 3)² = -9

Solution:

Subtract seven from both sides. After you do that, simplify, then divide both sides by -4.

Also, quadractic bit of it is x = 3i + 3, x = -3i + 3.

Answer:

x=3+3i, 3-3i

Step-by-step explanation:

-4(x-3)²+7=43

(x-3)(x-3)= x²-6x+9

-4(x²-6x+9)+7=43

-4x²+24x-36+7=43

-4x²+24x-29=43

-4x²+24x-72=0

-x²+6x-18=0

Quadratic formula: -b+√(b²-4ac)  / 2a

-(-6)+√((-6)²-4(1)(18))   /  2(1)

6+√(36-72)   /2

6+√(-36)   / 2

x=6+6i   / 2

x=3+3i, 3-3i

Answer:

Step-by-step explanation:

Your first two answers are incorrect. Radius = 5 km

Height = 12 km

volume of cone = πr²h/3 = π5²⋅12 = 300π km³

300π ≈ 942 km³

Answer and Step-by-step explanation:

The correct answer choice would be to grind the solvent into smaller pieces.

When the solid is in smaller pieces, it would take less time for the dissolver to dissolve the smaller bits, since the pieces are smaller and take up less volume for the dissolver to go through.

With a bigger solid, the dissolver would just chip away at the solid before eventually dissolving the solid, although this could take some time.

Answer:

Scale factor = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Formula for the scale factor is,

Scale factor = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the original}}[/tex]

                    = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the bridge}}[/tex]

                    = [tex]\frac{\text{Width of the model}}{\text{Width of the bridge}}[/tex]

                    = [tex]\frac{7}{35}[/tex]

                    = [tex]\frac{1}{5}[/tex]

Therefore, scale factor of the model to the real bridge = [tex]\frac{1}{5}[/tex]

Answer:

1-r

Step-by-step explanation:

decay meaning decrease. r stays the same and 1 + r increases but 1 - r decreases so 1 - r

Answer:

you have to subtract those two numbers

Answer:

Step-by-step explanation:

B = 22 × 3 × 52?—or is it supposed to be

B = 2² × 3 × 5² ?

A = 2² × 3 × 5

B = 2² × 3 × 5²

GCF = 2² × 3 × 5 = 60

A = 2² × 3 × 5

B = 22 × 3 × 52 = 2³ × 3 × 5 × 11 × 13

GCF = 2² × 3 × 5 = 60

Answer:

where are the answers???

Step-by-step explanation:

Answer:

36

Step-by-step explanation:

We are dealing with imaginary numbers, which works differently than a normal problem.

Let's combine (9i) and (i^2) and create a multiplication problem,

9ii^2 * 4i

Multiply the constants :

[tex]36i^2ii[/tex]

We see 4 i's in this problem, add them all together :

[tex]36i^4[/tex]

4 i's are equal to 1, now multiply the constant :

[tex]36 * 1[/tex]

Answer:

2700

Step-by-step explanation:

Given data

Time= 3 years

Principal= 30000

Rate= 3%

The simple interest formula is given as

SI=PR/100

substitute

SI= 30000*3*3/100

SI= 270000/100

SI= 2700

Hence the Interest is 2700

MARK ME BRAINLIEST! :D

Answer:

162°

Step-by-step explanation:

To convert from radian to degree measure

degree measure = radian measure × [tex]\frac{180}{\pi }[/tex] , then

degree = [tex]\frac{9\pi }{10}[/tex] × [tex]\frac{180}{\pi }[/tex] ( cancel π and 10/ 180 to simplify )

            = 9 × 18

           = 162°
