$1,242
$2,285
$1,116
$1,899
$1,649
$1,423 and $1,242 -again.....what is the range of the prices shown above?

Answers

Answer 1
Answer: So,

The range will simply be the absolute value of the difference between the highest and lowest price.

The highest price is $2285.

The lowest price is $1116.

The absolute value of the difference between these two prices is:

|2285 - 1116| = 1169

The range of the prices for the gold phone is $1169.

A right triangle has the leg lengths of 3X and 40 and a hypotenuse of length 5X. How long are the sides?

Answers

Answer:

Hypotenuse = 10 units

Step-by-step explanation:

According to the Pythagoras theorem:

{hyp}^(2) = {(one \: leg) }^(2) + {(other \: leg)}^(2) \n \therefore \: {(5x)}^(2) = {(3x)}^(2) + {40}^(2) \n \therefore \: {25x}^(2) = {9x}^(2) + 1600 \n \therefore \: {25x}^(2) - {9x}^(2)= 1600 \n \therefore \: {16x}^(2)= 1600 \n \therefore \: {x}^(2)= (1600)/(16) \n \therefore \: {x}^(2)= 100 \n \therefore \: {x}= 10 \n

Hence, length of hypotenuse = 10 units.

1. Maritza is baking cookies to bring to school and share with her friends on her birthday. The recipe requires eggs for every cups of sugar. To have enough cookies for all of her friends, Maritza determined she would needeggs. If her mom bought cups of sugar, does Maritza have enough sugar to make the cookies? Why or why not?

Answers

Answer:

Maritza has not enough sugar to make the cookies.

Step-by-step explanation:

Missing data

The recipe requires 3 eggs for every 2 cups of sugar.

Maritza determined she would need 12 eggs.  

Her mom bought 6 cups of sugar.

Writing data as a proportion gives

(3 eggs)/(2 cups of sugar) = (12 eggs)/(x cups of sugar)

Omitting units

3/2 = 12/x

Multiplying by x in both sides

3/2 *x = 12

Dividing by 3 and multiplying by 2 on both sides

x = 12*2/3

x = 8 cups of sugar

So, 6 cups are not enough.
first we need to know how many kids how much eggs and sugar to answer this sorry

How do you convert 0.65 into a fraction

Answers

so its 0.65 so make that 65. then make it 65 over 100 then find 65 and 100's gcf (greatest common factor) then divide until its fully reduced
0.65 is just like 65/100, all you gotta to do is turn 0.65 to a reg. number over a 100,hope that wasn't too confusing.

-1/8/-5/4=the numerator of the first value will be multiplied by the denominator of the second i.e 1*4 and similarly 8 will be multiplied by 5like this -1/8 * -4/5this will give 1/10 or 0.1 which is actually the right answe
