Evan loves to compete in triathlons. At his most recent race, he finished in 189 minutes. That is 10% less time than his previous race took. What was Evan's finishing time at the previous race?

Answers

Answer 1

Answer:

x = 210 minutes

Step-by-step explanation:

We can say that the previous race's finishing time was x and it was equal to 100% or 1.

We know that the current race's finishing time which is 189 minutes is 10% less than previous one's finishing time, so current race's finishing time can be said to be equal to 90% or 0.9.

Using the ratio and proportion, we can calculate the x to be,

1 : x

0.9 : 189

0.9 : 1  =  189 : x

0.9 * x = 1 * 189

x = 189 / 0.9

x = 210 minutes

Anna and Jason have summer jobs stuffing envelopes for two different companies. Anna earns $14 for every 400 envelopes she finishes. Jason earns $9 for every 300 envelopes he finishes. I need someone to solve this but represent it on a table instead of a graph.

Answers

Answer:

Q1:  20,000 envelopes

Q2: Savings = $700

Step-by-step explanation:

Let the number of envelopes stuffed by each be "x"

We can create 2 equations, each for Anna and Jason, equate them and find our answer.

For Anna:

$14 for 400, so

14/400 = $0.035 PER ENVELOPE

Savings for Anna is  0.035x

For Jason:

Already has 100 (fixed)

Gets $9 for 300 envelopes, so

9/300 = $0.03 PER ENVELOPE

Savings for Jason is  100 + 0.03x

We equate and solve for x:

So, For both their savings to be equal, they need to stuff 20,000 envelopes

Their savings would be:

0.035x

or 100 + 0.03x

We can plug in x = 20,000 in any one equation, the answer would be same.

So,

0.035(20,000) = $700

savings = $700

Step-by-step explanation:

equation: y = x - 6 + x^2

(6,0) (7,1) (8,4) (9,9)

I figured this out by looking at the point (6,0). To get 0 (y), you have to subtract 6. Knowing this, I subtracted 6 from the rest of the coordinates, leaving me with numbers that are able to be squared to get y. This led me to the equation x - 6 + x^2.

Wilmer went up a hill for x minutes at a speed of y kilometers per minutes. Then he went down the same path at a speed of z kilometers per minute, and it took him w minutes to do it. Write an equation that relates x, y, z, and w. (The wording for this question really confuses me. And I do not understand which variable to put on it's own.) PLEASE ANSWER

Answers

Answer:

[tex]xy=wz[/tex]

Step-by-step explanation:

Given that:

Speed of Wilmer up the hill = [tex]y[/tex] km/min

Time taken up the hill = [tex]x[/tex] minutes

Speed of Wilmer down the hill = [tex]z[/tex]  km/min

Time taken up the hill = [tex]w[/tex] minutes

Distance can be calculated by multiplying the Speed with Time i.e.

The formula for distance is given as:

[tex]Distance = Speed \times Time[/tex]

Distance up the hill = [tex]y\times x =xy\ kilometers[/tex]

Distance down the hill = [tex]z\times w =wz\ kilometers[/tex]

It is well known that, the distance up the hill and down the hill will be same.

Putting both the values equal, we get:

Step-by-step explanation:

This how you but this decimals and fractions from least to greatest. I hope this helps

First, you want to get all you options to be decimals.
146/25 is 5.84. 5 17/20 as an improper fraction is 117/20 because 20 times 5 is 100 and then add 17. 117/20 is 5.85.

Apples: $(2x) per pound
Grapes: $(6x - 5) per pound
Oranges: $(x + 2) per pound
A shopper purchases one pound each of
apples, grapes, and oranges and spends
$10.50. How much is spent on each type
of fruit?

Answers

Answer:

x= 1.5 $

Step-by-step explanation:

Hi there,

This is a tough question. Let us find out how to tackle it.

From the problem, we see that we 'll have to find x to figure out how much each type is. The only real number of money we get is 10.50$ - the amount the shopper spent. Let's divide this money into respective parts:

He bought 1 pound of apple => the cost of all the apple he bought is 1 ( pound) × (2x) ($ per pound) = 2x $

Do the same with Grapes and Oranges, we can easily see that he spent 6x-5 $ on grapes, x+2 $ on oranges.

The total amount he spent 10.50$ is now equal to (2x) + (6x-5) + (x+2).

Next we can change this equation, just so we find x easier:

10.50$ = (2x) + (6x-5) + (x+2)

10.50$ = 2x + 6x + x + 2 - 5

10.50$= 9x - 3

13.50$= 9x

x= 1.50 $

Thus, we can now calculate the price of each type. Apples are 3$ per pound, grapes are 4$ per pound, oranges are 3.50$ per pound.

HOPE YOU'LL LEARM WITH JOY AND GOOD GRADE

Answer:

Shopper spend on Apples $3 , on Grapes $4  and  on Oranges $3.5

Step-by-step explanation:

We are given:

Apples: $(2x) per pound

Grapes: $(6x - 5) per pound

Oranges: $(x + 2) per pound

A shopper purchases one pound each of  apples, grapes, and oranges and spends  $10.50.

It can be written as: [tex]2x+6x-5+x+2=10.50[/tex]

We need to find how much the shopper spend on each fruit.

Solution:

Now, we need to find value of x by solving equation

[tex]2x+6x-5+x+2=10.50[/tex]

Solving:

[tex]2x+6x+x+2-5=10.50\\9x-3=10.50\\9x=10.50+3\\9x=13.5\\x=\frac{13.5}{9}\\x=1.5[/tex]

The value of x is: x=1.5

Now finding cost of one pound each fruit by putting x=1.5

Apples: $(2x) per pound  

$2x= 2(1.5) = $3

Grapes: $(6x - 5) per pound

$(6x-5) = (6(1.5)-5)= $4

Oranges: $(x + 2) per pound

$(x+2)=(1.5+2)=$3.5

So, shopper spend on apples $3, on Grapes $4 and on Oranges $3.5.

49
1
2
inches long?

Answers

9514 1404 393

Answer:

  6

Step-by-step explanation:

We estimate the number as 49/8 ≈ 6. We can check to see if this is too many by finding the chain required for 6 bracelets:

  6 × 8 1/4 = 6×8 +6×1/4 = 48 +6/4 = 49 1/2

Sue can make 6 bracelets.

_____

You can also divide the total length of chain by the amount per bracelet:

  (49 1/2)/(8 1/4) = (99/2)/(33/4)

  = (99/2)(4/33) = (99/33)(4/2)

  = (3)(2) = 6

Answer:

 6

Step-by-step explanation:

We estimate the number as 49/8 ≈ 6. We can check to see if this is too many by finding the chain required for 6 bracelets:

 6 × 8 1/4 = 6×8 +6×1/4 = 48 +6/4 = 49 1/2

Sue can make 6 bracelets.

_____

You can also divide the total length of chain by the amount per bracelet:

 (49 1/2)/(8 1/4) = (99/2)/(33/4)

 = (99/2)(4/33) = (99/33)(4/2)

 = (3)(2) = 6

if you shift the reciprocal parent function, f(x)=1/x, right 4 units, what is the equation of the new function​

Answers

Answer: I think it is f(x)=1/(x-4)

Step-by-step explanation:

By taking f(x), and applying a left or right and/or up or down transformations to it, the function could be written using the equation f(x-h)+k.

Doing so will make the graph of the function move h units to the left or right. (Positive or negative) (make sure the operation before the h is subtraction when determining the sign of h)

Also, when finding k (up and down) (positive or negative) apply this function.

f(x)=(x-h)+k

As a result, plug in your right 4 units as h, and since you are not needing to move up or down k would be 0. So, f(x)=1/(x-(4))+0 or simplified, f(x)=1/(x-4)

F(x)=1/x-4
