i need help with this please

Answer:

19.0 cm

Step-by-step explanation:

a^2+b^2=c^2

1^2+b^2=19^2

1+b^2=361

(subtract one from both sides)

b^2=360

(now square root to get rid of the ^2)

[tex]\sqrt{b^2}[/tex]=[tex]\sqrt{360}[/tex]

b=18.97 rounded to the tenths place is 19.0

Answer:

The length of the other leg is 19 cm (rounded to the nearest tenth).

Step-by-step explanation:

In order to solve this, we need to know the Pythagoras theorem which states that...

[tex]c^{2} = a^{2} +b^{2}[/tex]  (Where c is the length of the hypotenuse and a and b are the lengths of the legs)

Now just substitute the values to find the length of the other leg, and we get...

[tex]c^{2} = a^{2} +b^{2}\\19^{2} = 1^{2} + b^{2} \\b^{2} = 19^{2} - 1^{2} \\b^{2} = 361 - 1\\b^{2} = 360\\b = \sqrt{360} \\[/tex]

b ≅ 19

Therefore the length of the other leg is around 19 cm.

Answer:

P(A) and P(B) = P(A) x P(B)

P(A) = number gray/total number of sections = 6/8 = 3/4

P(B) = number of reggae songs/total number of songs = 2/8 = 1/4

P(A) and P(B) = (3/4)(1/4) = 3/16

Step-by-step explanation:

Answer: 3/4 (0.75)

Step-by-step explanation:

6 out of 8 sections are green.

So there is a 6/8 probability that it will land on green.

6/8 = 3/4.

Answer:

(x+4)x

Step-by-step explanation:

The factor of the expression into an equivalent form x² + 4x would be;  x(x + 4)

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.

We need to factor the expression into an equivalent form x² + 4x

This expression could also be given by;

x² + 4x

Then factor out x we get;

x² + 4x =  x(x + 4)

Hence, the expression into an equivalent form x² + 4x would be; x(x + 4)

Answer:

3.50ft

Step-by-step explanation:

Given data

Volume= 180ft^3

The expression for the volume of a sphere is given as

Volume=4/3πr^3

substitute

180=4/3*3.142*r^3

180=12.568/3*r^3

180=4.189*r^3

r^3= 180/4.189

r^3= 42.969

cube root both sides

r= ∛ 42.969

r= 3.50ft

Hence the radius is 3.50ft

Answer:

Step-by-step explanation:

Given two angles: 47 and 90

Do 180 minus 47 + 90 to get the third angle

[tex]x = 180 - (47 +90)\\x = 180 - 137\\x = 43[/tex]

Answer:

x = 5

Step-by-step explanation:

Because the red-marked lines are parallel, we know that the ratios are the same

5x : 45 = 20 : 36

5x/45 = 20/36

5x * 36 = 20 * 45

5x * 4 = 20 * 5

5x * 1 = 5 * 5

x = 5

The Answer Is 2,592

This is because this is a geometric sequence, every number is multiplied by -6 to find the next number in the sequence.

Answer:

Slope is -2.8 so D

Step-by-step explanation:

I got -14/5 which converted is -2.8

Add up the same sides of both equations to eliminate x :

(x - 2y) + (-x + 3y) = 8 + (-5)

(x - x) + (-2y + 3y) = 8 - 5

y = 3

Then

x - 2y = x - 6 = 8   →   x = 14

Answer:

D. 17

Step-by-step explanation:

1.  Set up an equation  (2x + 5) + (3x + 10) = 100

2.    2x + 3x= 5x   and  5 + 10 = 15

3. The equation simplified  5x + 15 = 100

4. Move the 15 to the other side of the equation.   5x = 100 - 15

5.    5x = 85

6. Finally, divide   85/5

7. Our final answer is 17.

Answer:

  16π/17 radians ≈ 169.41°

Step-by-step explanation:

The arc length of the sector is the circumference of the cone:

  C = 2πr = 2π(4 cm) = 8π cm

The angle and arc length are related by ...

  s = rθ . . . . . θ in radians

  8π cm = (8.5 cm)θ

  θ = 8π/8.5 = 16π/17 . . . . radians

bii) The angle of the sector is 16π/17 radians ≈ 169.41°.

Answer:

169° (3sf)

Step-by-step explanation:

the area of a circle multiplied by the angle over 360 gives you ans.

x/360 × π × r²=34π -> ur ans frm part i

x × π(8.5²)=12240π

x × 72.25=12240

x=169.41°

Answer:

1. Subtraction property

2. Division property

Step-by-step explanation:

Question has missing details.

Kira's steps are:

[tex]\frac{7}{2} - 2x = \frac{11}{2}[/tex]

[tex]\frac{7}{2}- \frac{7}{2} - 2x = \frac{11}{2}- \frac{7}{2}[/tex]

[tex]- 2x \div -2= \frac{4}{2} \div -2[/tex]

[tex]x = -1[/tex]

Required

The properties used

For the first step, we have:

[tex]\frac{7}{2} - 2x = \frac{11}{2}[/tex]

To get to step 2, Kira subtracted [tex]\frac{7}{2}[/tex] from both sides.

i.e.

[tex]\frac{7}{2}- \frac{7}{2} - 2x = \frac{11}{2}- \frac{7}{2}[/tex]

This property is subtraction property

In the second step, where x is isolated.

[tex]- 2x \div -2= \frac{4}{2} \div -2[/tex]

Both sides of the equation were divided by -2  to give:

[tex]x = -1[/tex]

This property is division property
