a) choosing a vowel from the set {a, e, i, o, u}

b) choosing an odd number from the set {2,4,6,8,9}

c) choosing a consonant from the set {b, c, d, e, f}

d) choosing an even number from the set {1,3,5,7,9}

Plz hurry. AND NO LINKS PLZ

Answers

Answer: c) choosing a consonant from the set {b, c, d, e, f}

Step-by-step explanation:

Since all of the choice sets have 5 values each, a 0.8 chance = 80% = [tex]\frac{4}{5}[/tex].

So find the set with 4 values that meet the criteria.

A: 5/5 = 1 = 100%

B: 1/5 = 0.2 = 20%

C: 4/5 = 0.8 = 80%

D: 0/5 = 0 = 0%

the answer is C: choosing a consonant from the set {b, c, d, e, f}

In the figure shown, line AB is parallel to line CD.

Part A: What is the measure of angle x? Show your work. (5 points)

Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)

Answers

Answer:

Part A

x is 46°

Part B

Alternate angles are angles that are in relatively opposite locations relative to a transversal

Step-by-step explanation:

Part A

∠DRP = 110° (Given)

∠QPA = 64° (Given)

∠QPR =

Given that AB is parallel to CD, we have;

∠DRP is congruent to ∠APR (Alternate angles to a transversal RP of parallel lines AB and CD)

Therefore, ∠APR = 115°

∠APR = ∠QPA + ∠QPR (Angle addition postulate)

∴ 115° = 64° + ∠QPR

∠QPR = 110° - 64° = 46°

x = 46°

Part B.

Given that AB is parallel to CD, the lines common (that intersects) both lines are the transversal lines

The angles formed between the parallel lines and the transversal lines have special relationships based on their position with respect to each other

In the question, the angle 110° given between CD and the transversal RP, is found to at an alternate position to the angle ∠APR between the same transversal RP and AB and given that alternate angles are always equal, angle ∠APR is therefore also equal to 110°.

X would equal 46 degrees

We need to use the formula :-

2 (l + b) × h ---> For Lateral surface area

2(30+30) h = 7200

2×60×h = 7200

120 × h = 7200

h = 7200/120

h = 60 cm

Now, volume = l×b×h

= 30×30×60

= 54000 cm³ is the required answer.

Answers

Answer:

A) ≈ 6.93

B) ≈ 0.02

Step-by-step explanation:

Formula : a² + b² = c²

2.4² + 6.5² = c²

5.76 + 42.25 = c²

c = √48.01

c ≈ 6.93

Formula = c² - a² = b²

1/3² - 1/4² = b²

1/9 - 1/16 = b²

b = √7/144

b ≈ 0.02

-Chetan K

Answer:

Data:

P = 6.5 cm

B = 2.4 cm

H = ?

▪ [tex]H^{2} = P^{2} + B^{2}[/tex]

=> [tex]H^{2} = 6.5^{2} cm+ 2.4^{2}[/tex] cm

=> [tex]H^{2}[/tex] = 48.01 cm

=> H = [tex]\sqrt{48.01}[/tex] cm

=> H = 6.92 cm

Ans: the length of the hypotenuse is 6.92 cm.

Data:

P = [tex]\frac{1}{4}[/tex]

H = [tex]\frac{1}{3}[/tex]

B = ?

▪ [tex]H^{2} = P^{2} + B^{2}[/tex]

=> [tex]\frac{1}{3}^{2}[/tex] cm = [tex]\frac{1}{4}^{2}[/tex] cm+ [tex]B^{2}[/tex]

=> 0.11 cm = 0.06 cm + [tex]B^{2}[/tex]

=> [tex]B^{2}[/tex] = 0.11 cm - 0.06 cm

=> B = [tex]\sqrt{0.05}[/tex] cm

=> B = [tex]\frac{11}{50} [/tex] cm

Ans: the length of the other side is [tex]\frac{11}{50} [/tex] cm.

Answers

Answer: 10 inches

Step-by-step explanation:

If the two triangles are similar, that means their sides are proportional to each other.

JK = 15JL = 15 + 6 = 21JM = 14

The proportion would look like this:

[tex]\frac{JK}{JL} =\frac{JN}{JM}\\[/tex]

Substitute in the values:

[tex]\frac{15}{21} =\frac{JN}{14}[/tex]

Cross-multiply and solve for JN:

[tex]21*JN=15*14\\JN=\frac{15*14}{21} =\frac{210}{21} =10[/tex]

Answer:

10 inches

Step-by-step explanation:

JM=14<JL=21

And you know that JN=X<JK=15

You also know that JM=14>JN=x

KL=6 so NM=4

JM= (14) - NM (4)= 10

A realtor earns 3% commissions on any house sale she makes. If she sells a house for $125000 how much commission is she going to earn? Answer ASAP please for good explanation

Answers

Answer:

$3750

Step-by-step explanation:

It's simple, just find the 3%of $125000

IF YOU SATISFIED WITH THE ANSWER, DON'T FORGET TO MAKE ME A BRAINLISTS.

The answer is 3750

Whenever you have a percentage it will simplify to that out off 100 so if you have 50% it will be equivalent to 50/100 which is equal to .50. So that will be the same with 3% it will be 3/100 and that will make it .03. Than you will multiply it with how much the house sold for which is 125000. So .03*125000 is 3750.
