If the ratio of y to x is equal to 3 and the sum of y and x is 80, what is value of y

Answer:

Ok

Step-by-step explanation:

Answer:

a = -3

b = -8

Step-by-step explanation:

Equation for a line is:

y-coordinate = (slope * x-coordinate) + y-intercept

For (3, -4): -4 = (-2 * 3) + y-intercept

y-intercept = 2

Equation for all points on this line is:

y = -2*x + 2

For (a, 8): 8 = (-2 * a) + 2

For (5, b): b = (-2 * 5) + 2

Answer:

The answers are, in order:

1. Isolate

2. substitute

3. variable

Notes:

The rabbit population in Central Park in 2005 is 192 rabbits.

To find the rabbit population in Central Park in 2005, we need to calculate the growth from 1995 to 2005.

From 1995 to 2005, there is a total of 10 years.

Using the growth rate of 8.5% per year, we can calculate the population in 2005:

Population in 2005 = 85 rabbits(1 + 0.085)¹⁰

Calculating this expression:

Population in 2005 = 85 rabbits(1.085)¹⁰

= 85 rabbits × 2.2609

= 192 rabbits

Therefore, the estimated rabbit population in Central Park in 2005 is 192 rabbits.

Step-by-step explanation:

since KLJ is a parallelogram, it can be split into 2 congruent triangles, as seen above. The angles remain the same, so we know angle KJL is also 25 degrees. Using the triangle angle sum theorem (all sides of a triangle add up to 180 degrees), we can determine the missing angle measure is 25 degrees. It would have been nice if the question told us JKLM was also a rhombus.

9514 1404 393

Answer:

  14 units

Step-by-step explanation:

The angle bisector divides the sides proportionally.

  BD/BA = CD/CA

  (x+4)/8 = (2x+1)/12

  3(x +4) = 2(2x +1) . . . . . multiply by 24 (the least common denominator)

  3x +12 = 4x +2 . . . . . . . eliminate parentheses using the distributive property

  12 = x +2 . . . . . . . subtract 3x

  10 = x . . . . . . . . . subtract 2

Then the length of BD is ...

  BD = x +4

  BD = 10 +4 . . . . substitute the value of x

  BD = 14

Answer:

a or b

Step-by-step explanation:

Answer:

Let the adjacent angles of the rhombus be 2x and 3x. We know that the sum of the measures of the adjacent angles is equal to 180°. AD = DC = 3 × 36° = 108°. Hence , the angles of the rhombus are 72° , 108° , 72° and 108°.

Step-by-step explanation:

Answer:

Let the adjacent angles of the rhombus be 2x and 3x.

we know that the sum of the measures of the adjacent angles is equal to 180°.

2x+3x=180

=5x=180

=x=180/5

=x=36°

Hence,AB =BC=2×36°=72°

AD=DC=3×36°=108°

Hence,The angles of the rhombus are 72°,108°, 72°and108°.

Answer:

10 pieces

Step-by-step explanation:

She gave herself 4 pieces, and each child 2 pieces. If she has 3 children, she gave them 6 pieces.

(3*2=6) and then you add with the amount she gave herself, (6+4) that would be 10.  She started with 10 pieces.

An equation would be:

x= 4+(2*3)

Answer:

[tex]y = \frac{2}{5} x + 3[/tex]

Step-by-step explanation:

2x - 5y = -15

Firstly, you will need to isolate the variable you are solving for, in this case, y.

2x - 2x - 5y = -15 - 2x

-5y = -15 - 2x

-5y/-5 = -15/-5 - 2x/-5

A negative divided or multiplied by a negative is positive.

[tex]y = 3 + \frac{2}{5} x[/tex]

Rearrange.

[tex]y = \frac{2}{5} x +3[/tex]

the series : 6/8 , -1/8 , 2/8 , -24/8 , -4/8 , 8/8

the ascending arrangement : -24/8 , -4/8 , -1/8 , 2/8 , 6/8 , 8/8

=

-3 , -1/2 , -1/8 , |1/4| , 3/4 , |-1|

Answer:

We conclude that the total amount accrued, principal plus interest,  from compound interest on an original principal of  $2500 at a rate of 5% per year compounded 6 times per year over 8 years is $3723.38.

Step-by-step explanation:

Given

Principle P = $2500

Interest rate r = 5% = 0.05

Time period t = 8 years

To determine

Accrue Amount A = ?

Using the compound interest equation

[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]

where:

A represents the Accrue Amount

P represents the Principal Amount

r represents the interest rate

t represents the time period in years

n represents the number of compounding periods per unit t

Important tip:

now substituting P = 2500, r = 0.05, t = 8 and n = 6 in the equation

[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]

[tex]A=2500\left(1+\frac{0.05}{6}\right)^{\left(6\right)\left(8\right)}[/tex]

[tex]\:A=2500\left(1+\frac{0.05}{6}\right)^{48}[/tex]

[tex]A=2500\times 1.48935[/tex]      ∵  [tex]\left(1+\frac{0.05}{6}\right)^{48\:\:}=1.48935[/tex]

[tex]A=\:3723.38[/tex] $

Therefore, we conclude that the total amount accrued, principal plus interest,  from compound interest on an original principal of  $2500 at a rate of 5% per year compounded 6 times per year over 8 years is $3723.38.

Answer:

$44.80

Step-by-step explanation:

Here' s  an equation to help you with percent problems:    part            %

                                                                                               -------    =    -----

                                                                                              whole         100

Because you want to find 12%, the % in the equation would be replaced with 12. The part would be x because that's what u need to find. The whole would be 40. Cross multiply to get 100x = 480. Divide 480 by 100 to get x = 4.80. Add 4.80 to 40.00 to get the final price. The final price is $44.80.
