(y+3):(y+5)=k:1

show that y=(5k-3)/(1-k)

hence y=(5k-2)/(1-k)

Answers

Answer 1

hi,

Express the ratios in fractional form, that is

= ( cross- multiply )

y + 3 = k(y + 5) ← distribute

y + 3 = ky + 5k ( subtract ky from both sides )

y - ky + 3 = 5k ( subtract 3 from both sides )

y - ky = 5k - 3 ← factor out y from each term on the left side

y(1 - k) = 5k - 3 ← divide both sides by (1 - k)

y = 5k- 3

____

1 - k

20. Marissa has a $50, $20, $10, $5, and $1 bill in
her wallet. She takes the bills out and
randomly line them up. What is the
probability that the first bill is greater than
$5?

Answers

Answer: I believe it would be 60% tell if I am wrong

Step-by-step explanation:

The probability of getting first bill is greater than $5 is 1/5 or 0.2

Probability:

The probability of any event is the mathematical possibility of that event.

Probability is always lies between 0 to 1

Sure event has probability 1 while impossible event probability 0

The formula for probability is

Probability = [tex]\frac{number of favorable event}{total number of event}[/tex]

How to find probability?

Here the total event is

S = {$1, $5, $10, $20, $50}

Total number of events = 5

The probability of find greater than $5 is

Probability = 1/5 = 0.2

Hence the final answer is 0.2

Mr. Herman's class is selling candy for a school fundraiser. The class has a goal of raising $500 by selling c
boxes of candy. For every box they sell, they make $2.75.
Write an equation that the students could solve to figure out
how many boxes of candy they need to sell.

Answers

500 = 2.75c


500 is your total, 2.75 represents the price of a singular box, and c is how many boxes sold.


Hope this helps!

Answer:

500=2.75c

Step-by-step explanation:

500= 2.75c

Isolate c by dividing 2.75 on each side

500/2.75 =181.818181818 which is about 181.8

So the students need to sell about 181.8 boxes of candy in order to reach their goal of $500.

The snail moves at a faster rate then the ant does

Answer:

the snail

Step-by-step explanation:

in order to find who is faster you have to find how many inches each one does in one sec

Ant= 45/15 which is 3 inches per sec.

snail=12/3 which is 4 inches per sec.

so from the above calculations we can see that according to the question given a snail crawls faster than an ant runs

What does m=

Answers

Answer:

m = -14.6

Step-by-step explanation:

Given Question:To find the value of m

Given Equation:-57 = 16 + 5m

Solution:

=> -57 = 16 + 5m

=> 16 + 5m = -57

(On subtracting -16 from both sides)

=> 16 + 5m - 16 = -57 - 16

(On Simplification)

=> 5m = - 73

(On dividing both sides with 5)

[tex] = > \frac{5m}{5} = \frac{ - 73}{5} [/tex]

(On Simplification)

=> m = -14.6

Hence, required value of m = -14.6 (Ans)

Answer:

_14.6

Step-by-step explanation:

-57 = 16 + 5m

-57 - 16 = 5m

-73 = 5m

B. m∠1 + m∠3 = 180° because they form a straight angle.
C. ∠3 ≅ ∠6 because they are alternate interior angles.
D. ∠1 and ∠6 are supplementary because ∠3 ≅ ∠6 and m∠1 + m∠3 = 180°.

The true statement are

2. <1 + <3 = 180 because form a straight angle.

3.  ∠3 ≅ ∠6 because they are alternate interior angles.

4. ∠1 and ∠6 are supplementary because ∠3 ≅ ∠6 and m∠1 + m∠3 = 180°.

What are parallel lines?

Two lines in a plane are said to be parallel if they do not intersect when extended infinitely in both directions.

Two lines cut by a transversal line are parallel if the corresponding angles so formed are equal. In general, the corresponding angles are in relative positions and lie along the same side of the transversal.Two lines cut by a transversal line are parallel if the alternate interior angles so formed are equal. In general, the pairs of the alternate interior are found in the inner side but lie on the opposite sides of the transversal.Two lines cut by a transversal line are parallel if the alternate exterior angles so formed are equal. In general, the pairs of alternate exterior angles are found on the outer side but lie opposite each other.

As, from the figure

1. <3 = <2 because of vertically opposite angle.

Hence, it is false

2. <1 + <3 = 180 because form a straight angle.

Hence, it is true.

3.  ∠3 ≅ ∠6 because they are alternate interior angles.

Hence, it is true.

4. ∠1 and ∠6 are supplementary because ∠3 ≅ ∠6 and m∠1 + m∠3 = 180°.

How much would you have to deposit today to have an accumulated amount 20,000 in 20 years if yearly interest is 4.75% compounded continuously?

Answers

The principal investment required to get a total amount of $20,000.00 from compound interest at a rate of 4.75% per year compounded 12 times per year over 20 years is $7,749.34

Given data

Principal =?

Final amount = $20,000

rate = 4.75%

Time = 20 years

First, convert R as a percent to r as a decimal

r = R/100

r = 4.75/100

r = 0.0475 per year,

Then, solve the equation for P

P = A / (1 + r/n)^(nt)

P = 20,000.00 / (1 + 0.0475/12)^(12)(20)

P = 20,000.00 / (1 + 0.003958333)^(240)

P = $7,749.34

The property taxes on a house were $600. What was the tax rate if the house was valued at $100,000? Follow the problem solving and round your answer to the nearest hundredth of a percent, if necessary.

Answers

Based on the information given the tax rate if the house was valued at $100,000 is 60%.

Let $600= x%

Let $100,000=100%

Let the tax rate=x

Proportion:

600/100,000=x/100

Hence,

x=600×100/100,000

x=60,000/100,000

x=60/100

x=0.6%×100

x=60%

Inconclusion  the tax rate if the house was valued at $100,000 is 60%.
