HELP NOW DUE AT 11:55!!!! 30 POINTS!!!

A shark is swimming 10 feet below sea level and then swims up reaching 3 feet below sea level. What was its change in depth?

Answer:

C (16,-4)

Step-by-step explanation:

16+3*-4=4

16+(-12)=4

16-12=4

4=4

2*16+5*-4=12

32+(-20)=12

32-20=12

12=12

Step-by-step explanation:

Answer:

[tex]B = 50.5^\circ[/tex]

Step-by-step explanation:

Given

[tex]AB = 11[/tex]

[tex]BC = 7[/tex]

See attachment

Required

Determine [tex]\angle ABC[/tex]

[tex]\angle ABC[/tex] implies that we calculate the angle at B.

Given that:

[tex]AB = 11[/tex] --- Hypotenuse

[tex]BC = 7[/tex] --- Adjacent of B

We apply cosine formula

[tex]\cos(B) = \frac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos(B) = \frac{BC}{AB}[/tex]

[tex]\cos(B) = \frac{7}{11}[/tex]

[tex]\cos(B) = 0.6364[/tex]

Take arccos of both sides

[tex]B = cos^{-1}(0.6364)[/tex]

[tex]B = 50.5^\circ[/tex]

Answer:

b+.17

Step-by-step explanation:

Answer:

[tex]x=21.6[/tex]

Step-by-step explanation:

Use the Pythagorean theorem to solve this problem. The Pythagorean theorem states the following,

[tex]a^2 + b^c = c^2[/tex]

Where (a) and (b) are the legs or the sides adjacent to the right angle, and (c) is the hypotenuse or the side opposite the right angle.

Use the Pythagorean theorem in the right triangle with legs (15) and (18),

[tex](15)^2+(18)^2=c^2\\\\225 + 324=c^2\\\\549=c^2\\\\\sqrt{549}=c[/tex]

Use the Pythagorean theorem again in the right triangle with the legs (18) and (x)

[tex](x)^2+(18)^2=c^2\\\\\sqrt{x^2+324}=c[/tex]

Use the Pythagorean theorem one final time in the larger triangle,

[tex](\sqrt{x^2+324})^2+(\sqrt{549})^2=(x+15)^2\\[/tex]

Simplify, remember that anything to the power (2) is equal to the base (number under the exponent) times itself,

[tex]x^2+324+549=x^2+30x+225[/tex]

[tex]x^2+873=x^2+30x+225[/tex]

Inverse operations,

[tex]x^2+873=x^2+30x+225\\-x^2\\\\873=30x+225\\-225\\\\648=30x\\/30\\\\\frac{648}{30}=x\\\\21.6=x[/tex]

Answer:

y = -3/11x + 4/11

Step-by-step explanation:

y2 - y1/ x2 - x1

-1 - 2/ 5 - (-6)

-3 / 11

y = -3/11x + b

-1 = -3/11(5) + b

-1 = -15/11 + b

4/11 = b

Answer:

The expression that represents the approximate area of the circle in square inches is;

9.42 times 3

Step-by-step explanation:

From the question, we have;

The shape of the figure which Kyra is finding the area for = A circle;

The number of equal pieces Kyra cuts the shape into = 8 equal sectors

The shape the sectors are arranged into = A parallelogram

The base of the parallelogram = 9.42 inches

The height of the parallelogram = 3 inches

Therefore, the area of the approximate parallelogram formed ≈  The area of the circle

The area of a parallelogram = The base × The height

∴ The area of the approximate parallelogram formed = 9.42 × 3 ≈ The area of the circle

The approximate area of the circle = 9.42 × 3 square inches.

Answer:

I love algebra anyways  

the ans is in the picture with the steps  

(hope it helps can i plz have brainlist :D hehe)

Step-by-step explanation:

Answer:

Angle 1: 40

Angle 2: 40

Step-by-step explanation:

A triangle's angles will ALWAYS add up to 180 degrees total, therefore you can subtract 100 from 180 to find what the measure of A and B are combined.

180 - 100 = 80

So now we know Angles A and B add to 80 degrees, but individually, each is half of that, so both are 40 degrees.

Answer:

I am not sure but

Step-by-step explanation:

try to use to website https://www.symbolab.com/solver/pre-algebra-calculator

you can chose what your learning and it gives you the right answer. make sure you put the numbers in correctly. if you don't it will mess every thing up for that problem. That one reason I have a B in math cuz i use that site for my math. and it shows you how to do it with steps

please give me a heart if the site really helps you guys :)

Answer:

4/21

Step-by-step explanation:

Answer:

63 degrees

Step-by-step explanation:

Since this is an isosceles triangle, the two bottom angles must be equal, while the top angle (in the way this specific triangle is oriented) must be different. Therefore, angle CDB is 63 degrees.

Answer:

∠CDB = 63°

Step-by-step explanation:

∠CBD and ∠CDB opposite side lengths are congruent (indicated by the little markings)

Because their opposite sides are congruent they are too congruent

So ∠CBD = ∠CDB

because ∠CBD = 63° ∠CDB also equal 63°

Answer:

1331 in^3

Step-by-step explanation:

Well a cube is all identical So followiung the volume for a cube formula

s^3 or in this case 11^3, its 1331.

It might be 0.432 because add all the mornings numbers, 19,2,6,16.

19+2+6+16 = 43.

How many Freshman? 19 so 19/43 and then you divide 19 and 43

19/43 and you get 0.4418604651 about and it looks to be close to 0.432.

[tex]\sqrt{53\\}[/tex]

Step-by-step explanation:

Use the distance equation ([tex]\sqrt{(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2} = D[/tex]and plug in the values for the distance D

√((-5-2)^2 + (-4 - (-2))^2) = √53
