What postulate are the triangles congruent by?

Answer:

The athlete's tangential velocity is 0.88 m/s.

Step-by-step explanation:

We have that the athlete completes 4 laps around a track with a radius of 25 meters in 12 minutes:

[tex] \omega = \frac{\theta}{t} [/tex]

Where:

ω: is the angular speed

θ: is the angular displacement

t: is the time = 12 min = 720 s

The angular displacement is:

[tex] \theta = 4 rev*\frac{2\pi rad}{1 rev} = 25.13 rad [/tex]

Now, the angular speed is:

[tex] \omega = \frac{\theta}{t} = \frac{25.13 rad}{720 s} = 0.035 rad/s [/tex]

Finally, the athlete's tangential velocity is:

[tex] v = \omega r = 0.035 rad/s*25 m = 0.88 m/s [/tex]

Therefore, the athlete's tangential velocity is 0.88 m/s.

Answer:

264  {feet}

below sea level

Step-by-step explanation:

Ascending means moving towards the surface.

So the submarine is 340 feet below sea level.

The submarine ascends 76 feet.

∴

340 − 76  =

264  below sea level.

Answer:

300 students

Step-by-step explanation:

There are two ways to solve this question.

60 is 20% of the total students

20÷100= 0.2

60÷0.2=300

Therefore there are 300 students

60 is 20% of the total students

60/20 = x/100

x= 60*100÷20

x= 6000÷20

x= 300

Therefore there are 300 students.

18x+3y=-21

slope -intercept form: y=mx+b

move 18x to the other side

sign changes from +18x to -18x

18x-18x+3y=-18x-21

3y=-18x-21

divide both sides by 3 to find slope-intercept form

3y/3=-18x/3-21/3

y=-6x-7

answer: y=-6x-7

Answer:

x= -1/6 y + -7/6

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Like terms are the ones with same variables.

2w + 5w - 6 + 4w = 2w + 5w + 4w - 6

                             = (2 + 5 + 4)w -6

                             = 11w - 6

The most simplified expression 2w + 5w - 6 + 4w is 11w - 6. So, the correct option is B.

To find the most simplified expression 2w+5w -6 +4w.

First we simplify the given expression:

2w + 5w - 6 + 4w

(2w + 5w) = 7w.

7w - 6 + 4w

(7w + 4w) = 11w.

11w - 6.

Therefore, the most simplified expression 2w+5w -6 +4w is 11w -6.

Answer:

y=x-2

a. 3=x-2

b. this isn't wrong??

c. 3=x-2

d. add 2 to both side so taht x is on its own so 5=x

e. yes

Answer:

C and E

Step-by-step explanation:

Im not entirely sure about A, because you are substituting so technically you changed it but the equation is still true (just as E says) but with more specific values.

B is not right because you can replace either y or x

D is not right because if you switch the equation to get the value of x you would make x= -3-2 which would be -5, not 5.

C.  4[tex]x^{2} \sqrt{3x}[/tex] is equivalent to the expression [tex]\sqrt{48x^{5} }[/tex] if x>0

An algebraic expression may be a blend of constants, coefficients, factors, and scientific operations. An algebraic expression can comprise of a number of terms or a few. Equivalent algebraic expressions are expressions that appear different but work the same way. If two algebraic expressions are equal, then on assigning the same value to the variables the two expressions will give the same value.At least two expressions are required to check for equality and You can substitute in nearly any value for the variable when trying to determine if two expressions are equivalent.

Expression:

[tex]\sqrt{48x^{5} }[/tex]  if x>0

= [tex]48^{1/2}(x^{5})^{1/2}[/tex]

= [tex]48^{1/2}x^{5/2}[/tex]

= (2×2×2×2×3[tex])^{1/2}x^{5/2}[/tex]

= 2×2×[tex]3^{1/2}[/tex]×[tex]x^{5/2}[/tex]

= 4[tex]\sqrt{3} x^{5/2}[/tex]

= [tex]4\sqrt{3}x^{2} x^{1/2}[/tex]

= [tex]4x^{2} \sqrt{3x}[/tex]

Therefore, [tex]\sqrt{48x^5}[/tex] = [tex]4x^{2} \sqrt{3x}[/tex] if x>0

Hence, 4[tex]x^{2} \sqrt{3x}[/tex] is equivalent to the expression  [tex]\sqrt{48x^{5} }[/tex] if x>0

Answer:

Arc SN = 65

Step-by-step explanation:

The relationship between these three is

RPQ = 1/2 (arc SN + arc QR)

70 = 1/2 (x + 75)                        Multiply by 2

140 = x + 75                              Subtract 75

x = 140 - 75

x = 65

Answer:

Wanye can only bowl 4 times.

Step-by-step explanation:

the expression for this equation is

20 = 4.25x + 1.90

subtract  1.90 from both sides

18.10 = 4.25x

See how many times 4.25 can go into 18.10

1.) 18.10 - 4.25 = 13.85

2.) 13.85 - 4.25 = 9.60

3.) 9.60 - 4.25 = 5.35

4.) 5.35 - 4.25 = 1.1

1.1 < 4.25 so you can't subtract it

the answer is 4 times

Answer:

2 hours: 27 miles, 3 hours: 40.5 miles, 3.5 hours: 47.25 miles

Step-by-step explanation:

1.) If a hiker hikes 9 miles in 2/3 of an hour, he will hike 4.5 (Half of 2/3 is 1/3 and half of 9 is 4.5) miles in 1/3 of an hour and 13.5 miles per hour. (1/3 times 3 gives us a whole and 4.5 times 3 is 13.5)

2.) 2 hours: 13.5 * 2 = 27 miles

3.) 3 hours: 13.5 * 3 = 40.5 miles

4.) 3.5 hours: 13.5 * 3.5 = 47.25 miles

9 miles in 2/3 of a hour.

in 1 hour = 9 X 3/2 = 18.2 miles

In 2 hrs = 27 miles

in 3 hrs = 54.6 miles

in 3.5 hrs = 63.7 miles

Answer:

David should pay £48 as deposit.

Step-by-step explanation:

Price of cooker = £320

Deposit price of Cooker = 15%

We need to find How much money does David pay as a deposit?​

For finding deposit money we will find:

15% of 320

Solving:

[tex]15\% \ of \ 320\\=15\% \times 320\\=\frac{15}{100}\times 320 \\=48[/tex]

So, David should pay £48 as deposit.

Answer:

y=4x-3

Step-by-step explanation:

Parallel lines will always have the same slope (the number that comes before x in an equation). So, we can plug in 4 to the equation.

y=4x+?

Let's say the ? is b. If we plug in the point (1,1) into y=4x+b, we get

1=4(1)+b

reduce

1=4+b

subtract 4 from both sides

-3=b

and now we can add b=-3 into the original answer, and we get y=4x-3!

Step-by-step explanation:

Total cups of chocolate available = 7 1/3 cups

each batch uses 2/3 of a cup of chocolate

To get the number of batches of muffin Jim can bake, we will use the equality postulate.

1 batch = 2/3 cup of a chocolate

x batch = 7 1/3 cups of chocolate

Cross multiply

2/3 x = 7 1/3

2/3 x = 22/3

cross multiply

2x * 3 = 3 * 22

6x = 66

x = 66/6

x = 11

Hence Jim can bake at most 11 batches of muffins

Answer:

The measure of angle X is 51°.

Step-by-step explanation:

The sum of all interior angles of a triangle is 180°.

For the △XYZ it is provided that

m∠Y = 55°

m∠Z = 74°

Compute the measure of angle X as follows:

m∠X + m∠Y + m∠Z = 180°

m∠X + 55° + 74° = 180°

m∠X = 51°

Thus, the measure of angle X is 51°.

Answer:

A

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°, thus

∠ A + ∠ B + ∠ C = 180°, so

95° + 35° + ∠ C = 180

130° + ∠ C = 180 ( subtract 130° from both sides )

∠ C = 50° → A
