Out of 20 words, Janet spelled 10 of them correctly. What percent of the words did Janet spell correctly?

The fraction \frac{10}{20} represents the 10 words that Janet spelled correctly out of all the words she spelled.

To find out what percent of the words that Janet spelled correctly, we can turn \frac{10}{20} into a percent.

Before we turn it into a percent, we can reduce it by dividing both the numerator and denominator by the Greatest Common Factor of 10 and 20 using 10.

10 ÷ 10 = 1

20 ÷ 10 = 2

1 ÷ 2 = 0.5

0.5 × 100 = 50%

Therefore, Janet spelled 50% of the words correctly.

You can use guess and check, and first, 2500 * (107.5%)^20 would get us 10619.6277506, and then 19 would guess us an answer that is less than 10000, so 20 months = 1 2/3 years.

Matthew is training to participate in a half marathon. The table below shows the number of miles he runs in weeks 1 and 2. Week Number of Miles Run 1 12.5 2 13.5 Each week, Matthew increases the number of miles he runs in the previous week by the same percent. How many miles does Matthew run in week 3? Do not round your answer

Answer:

14.58 miles.

Step-by-step explanation:

Matthew is training to participate in a half marathon.

The distance covered by Matthew on the first day is 12.5 miles.

The distance covered by Matthew on the second day is 13.5 miles.

The distance increased on the second day is, 13.5-12.5=1 mile.

The percentage will be,

=\dfrac{1}{12.5}\times 100\%

=0.08\times 100\%

=8\%

Hence, each day he runs 8% more. So the distance covered by him on day 3 will be,

=13.5+\left(13.5\times \dfrac{8}{100}\right)

=13.5+1.08

=14.58 miles

Which system of equations below has no solution? A. y = 4x + 5 and y = 4x – 5 B. y = 4x + 5 and 2y = 8x + 10 C. y = 4x + 5 and y = 1/4 + 5 D. y = 4x + 5 and y = 8x + 10

Answer:

A.  y = 4x + 5 and y = 4x – 5

Step-by-step explanation:

If the system of equations have the same slope and different y-intercept, then it will have no solution.

From the given options, let's find the slope and y-intercept.

A. y = 4x  + 5 and y = 4x - 5

Slope = 4 and y-intercepts are 5 and -5

Here we have the same slope and different y-intercepts. So, this is systems of equations have no solution.

B. y = 4x + 5 and 2y = 8x + 10 => y = 4x + 5

Both are the same equations.

This system  has an infinite number of solutions.

The answer is A)  y = 4x + 5 and y = 4x – 5

Find A ∩ B if A = {3, 6, 9, 12} and B = {2, 4, 6, 8, 10, 12}.

Answer:

The set A ∩ B contain {6, 12}

Step-by-step explanation:

Given : set A = {3, 6, 9, 12} and set B = {2, 4, 6, 8, 10, 12}

We have to find A ∩ B

Consider the given sets

Set A = {3, 6, 9, 12}

and set B = {2, 4, 6, 8, 10, 12}

Since, A ∩ B  includes those elements that are both in set A and set B.

Thus, the common elements of A and B are 6 and 12

So , the set A ∩ B contain {6, 12}

One pound of grapes costs $1.55. Which equation correctly shows a pair of equivalent ratios that can be used to find the cost of 3.5 pounds of grapes?

Answer:

Given the statement: One pound of grapes costs $1.55.

Let x be be the cost of 3.5 pounds of grapes.

Equivalent ratios states that the  two ratios that express the same relationship between numbers.

Therefore, by equivalent ratio:

\frac{1 pound}{cost of 1 grapes} =\frac{3.5 pound}{cost of 3.5 grapes}

then, we have;

\frac{1}{1.55}=\frac{3.5}{x}

Cross multiply the above equation; we hve

x = 1.55 \times 3.5

x = 5.425

therefore, the cost of 3.5 pounds of grapes is, $5.425

WORTH 10 POINTS! Mara decides to plot her neighborhood on a coordinate plane. She plots her house at the point (0,0), her school is located at (0,8), the library at (3,8), and the softball field is at (3,0). One day she decides that after school she will run by the library to grab a book, and then head to softball practice and then back home. How far on the coordinate plane does she travel starting at home that morning? Leave your answer in units. A) 11 units B) 14 units C) 19 units D) 22 units

Answer:

Option: D is the correct answer.

D) 22 units.

Step-by-step explanation:

Her home is located at: (0,0)

School at (8,0)

Library at (3,8)

and softball field is located at (3,0) on the coordinate plane.

Now, that morning she starts from home then goes to school then after school she goes to Library and then after library she goes to softball field and returns back home.

Home→ school → Library → Softball field → Home.

This means that she covers the boundary of the rectangle that is formed by the location of the points.

This means in order to find the total distance she traveled we need to find the perimeter of the rectangle.

Length of One side of rectangle(a)= 8 units.

Length of the other side of rectangle(b) = 3 units.

Hence,

Perimeter of rectangle= 2(a+b)

                                    = 2(8+3)

                                   =2×11

                                   = 22 units.

Hence, the total distance she traveled is:

                       22 units.

Joanne bought 3 baseball cards for $160. If the first card was as expensive as the combined price of the second and the third cards, and the second card cost $20 more than the third card, what is the price of the first card?

Let b represent the third card
let (b+20) represent the second card
let (2b+20) represent the first card


(2b+20)+(b+20)+b=160
                   4b+40=160
                          4b=160-40
                          4b=120
                       4b/4=120/4
                             b=30

   2b+20 
= 2(30)+20
= 60+20
= 80

   b+20
= 30=20
= 60


Therefore, the first card was $80, the second card was $50 and the third card was $30.

What is the weight in grams of 3.36*10^23 molecules of copper sulfate

Answer:

The weight in grams of 3.36\times10^{23} molecules of copper sulfate is 89.023 g.

Step-by-step explanation:

Given :  Molecules of copper sulfate 3.36\times10^{23}

To find : What is the weight in grams of 3.36\times10^{23} molecules of copper sulfate?

Solution :

Molar mass of copper sulfate (CuSO_4)

Cu=63.5

S=32

O=16

CuSO_4=63.5+32+4\times16= 159.5 g

We know, that 1 mole = Avogadro number

1 mole = 6.02\times 10^{23} molecules

6.02\times10^{23}  molecule weigh = 159.5 g

1 molecule weigh = \frac{159.5}{6.02\times10^{23}} g

So, 3.36\times10^{23} molecule weigh = \frac{159.5\times3.36\times10^23}{6.02\times10^{23}} g

=\frac{159.5\times3.36}{6.02} g

=\frac{535.92}{6.02} g

=89.023 g

Therefore, The weight in grams of 3.36\times10^{23} molecules of copper sulfate is 89.023 g.

Nuts.com sells raw almonds for $10 per pound and roasted pistachios for $12 per pound. Christopher spends $70, before taxes and shipping, to purchase 6.3 total pounds of nuts

Answer:

Christopher bought 3.5 pounds of roasted pistachios and 2.8 pounds of raw almonds.

Step-by-step explanation:

From the information given, we can write the following equations:

A+P= 6.3 ①

10A+12P= 70 ②

To resolve them, we have to isolate one of the variables in the first equation and then replace that in the second equation:

A=6.3-P ③

10(6.3-P)+12P=70

63-10P+12P= 70

2P= 70-63

P= 7/2=3.5

Now, that we have found the quantity of roasted pistachios, we can replace that in equation number 3 to find the quantity of raw almonds:

A= 6.3-3.5= 2.8
