En 4 años, Jake será dos veces mayor que Jane. Actualmente, Él es tres veces mayor que Jane. ¿Cuántos años tendrá Jake en 5 años?

Answers

Answer 1

Answer:

17 años

Step-by-step explanation:

Deje que la edad de Jane sea x

Deja la edad de Jake por y

y = 3x ------- 1

y + 4 = 2 (x + 4)

y = 2x + 8 - 4

y = 2x + 4 ------- 2

x = y / 3 ------- 3

Sustituye 3 en 2

y = 2 (y / 3) + 4

Multiplicar por 3

3y = 2y + 12

3 años - 2 años = 12

y = 12

Pero y = 3x

Por eso;

x = 12/3

x = 4

Dentro de cinco años

Jake = 12 + 5 = 17años

okay so angle O is connected to arc GU. to find angle O you musit find Arc GU

if Arc GO is 48 degrees and arc OU is 107 degrees, then you add those together.

107 +48=155

a circle has a total of 360 degrees

so 360-155= 205

205 is arc GU

205 divided by 2 will give you angle O

O is 102.5 degrees

the lablel on a 1/2- pound bag of wildflower seeds states that it will cover an area of 375 square feet . based on this information, what is the number of square feet that 1 pound of wildflower seeds will cover.​

Answers

Answer: so a 1 and 1/2 bag will cover 375

1=2/2

1 and 1/2=2/2 and 1/2=3/2

so 3/2 pound covers 375

2/2 pounds covers x

3/2pound=375

multiply both sides by 2 to get rid of the fraciton

3pound=750

divide both sides by 3

1pound=250 square feet so the answer is c. 250 square feet

Torrie could buy 8 jars of peanut butter for 27.12 or 7 jars of peanut butter for 26.53 what is the difference in the unit rates of the jars of peanut butter?

Answers

Answer:

The difference in the unit rates of the jars of peanut butter is 0.4.

Step-by-step explanation:

In order to find the unit rates, you have to divide each price for the amount of units purchased with that price, which is:

27.12/8=3.39

26.53/7=3.79

Now, that you have the unit rate for each case, you have to subtract 3.39 from 3.79 to find the difference in the unit rates:

3.79-3.39=0.4

According to this, the answer is that the difference in the unit rates of the jars of peanut butter is 0.4.

They say.. use Pythagorean theorem formula.... what is it?  :)  you have to remember it.    I'll put it below in case you don't remember  

Step-by-step explanation:

[tex]C^{2}[/tex] = [tex]A^{2}[/tex] +[tex]B^{2}[/tex]

and I know, you're thinking..... what's the deal with all the letters... how do I add those up? :D .....  you are right... you can't add letters... the letters are just the variables... or places holders for numbers... you can put many different numbers into each of them but... the relationship.... which is made by the equal sign.. must hold true for any numbers you put in for the variables.... sooo.. like this.. for your particular answer

[tex]19^{2}[/tex] = [tex]10^{2}[/tex] + [tex]y^{2}[/tex]  

( notice I've put in a  " y " , where there is a B in the formula above but that's just a letter... again.. which is just a variable... the place holder for a number...  soooo..... )

361 = 100 + [tex]y^{2}[/tex]        ( subtract 100 from each side of the " = "  )

261 = [tex]y^{2}[/tex]                 ( to undo the square on the wye... square root both sides)[tex]\sqrt{261}[/tex] = y  

my calculator tells me that [tex]\sqrt{261}[/tex] = 16.15549442

they say round to the nearest 10th... soooo..

16.2  is  the answer  :)

Belinda bought a car one year ago.
The value of this car has decreased by 15% to $14025.
Calculate how much Belinda paid for the car.

Guys please help me with the homework it’s available for me during the day only.

Answers

Answer:

$16,500

Step-by-step explanation:

The computation of the amount that should be paid for the car is shown below:

Since the car would be purchased one year ago

And, the value of the car would be decreased by 15% to $14025

So the amount that should be paid is

= $14025 × 100 ÷ (100 - 0.15)

= $16,500

If you vertically stretch the exponential function f(x) = 2* by a factor of 4, what
is the equation of the new function?
A. g(x) = 4.2%
B. g(x) = 24
C. g(x) = . 2*
D. g(x) = 2 .4*

Answers

Answer:

A. g(x) = 4.2%

Step-by-step explanation:

If you vertically stretch the exponential function f(x) = 2* by a factor of 4, what

is the equation of the new function?

A. g(x) = 4.2%

B. g(x) = 24

C. g(x) = . 2*

D. g(x) = 2 .4*

im not sure

The vertical stretch of the transformation of the function is g ( x ) = 4 ( 2 )ˣ

How does the transformation of a function happen?

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = 2ˣ

Now , the vertical stretch of a factor of 4 is given by

The transformed function is g ( x )

g ( x ) = 4 f ( x )

On simplifying , we get

g ( x ) = 4 ( 2 )ˣ

Hence , the transformed function is g ( x ) = 4 ( 2 )ˣ

The product of two consecutive numbers is 72. Use a quadratic equation to find the two sets of numbers.

Answers

Given:

The product of two consecutive numbers is 72.

To find:

The two numbers by using the quadratic equation.

Solution:

Let the two consecutive numbers are x and (x+1).

The product of two consecutive numbers is 72.

[tex]x(x+1)=72[/tex]

[tex]x^2+x-72=0[/tex]

Splitting the middle term, we get

[tex]x^2+9x-8x-72=0[/tex]

[tex]x(x+9)-8(x+9)=0[/tex]

[tex](x+9)(x-8)=0[/tex]

Using zero product property, we get

[tex]x+9=0[/tex] and [tex]x-8=0[/tex]

[tex]x=-9[/tex] and [tex]x=8[/tex]

If [tex]x=-9[/tex], then

[tex]x+1=-9+1[/tex]

[tex]x+1=-8[/tex]

If [tex]x=8[/tex], then

[tex]x+1=8+1[/tex]

[tex]x+1=9[/tex]

Therefore, the two consecutive numbers are either 8,9 or -9,-8.

Answer:

  1. domain and range are all real numbers

  2. the relation is linear

Step-by-step explanation:

When the graph of a function is a straight line, the relation is linear. (That's what linear means.)

A linear relation is of degree 1, so has odd degree. Any odd-degree polynomial function has a domain and range of "all real numbers."

Answer:

1. Domain : all the real numbers

Range = all the real numbers

yes, this relation represents a linear function. (linear functions are always a straight line when graphed.)

The owner makes $2 in sales per customer

Note: The "Amount of sales" label of the question is phrased poorly. s could be better labeled "profit from sales" or at least "Amount made from sales", etc.

Step-by-step explanation:

If you logically think about how the answer (now that you know it) relates to the question, it should make simple sense.

i.e. if you consider the first column where $24 is made from 12 customers, and divide the $24 made by the 12 customers, you'll see that each customer spends $2.

Answer:

the owner makes 2 dollars in sales every week

Step-by-step explanation:

on the chart/graph it shows 6 new customers every week and if you want to see how much more money the owner makes off of each customer then...

subtract the first weeks number of customers from the second weeks to get the answer of 6 new customers per week as you can see on the chart/graph (this really isnt to important though)

then divide the total number of customers for 1 week by the profits made for that week to get an answer of 2 dollars for customers.
