Good morning ☕️

Answer:

Step-by-step explanation:

Let our number be “ xy ”

the tens digit is four less than the units digit means y-4=x

Seven times the tens digit plus five times the units digit is equal to 56 means

7x+5y=56

now we have to solve the system:

y-4=x  (1)

7x+5y=56  (2)

(1) ⇒ y=4+x

Then we substitute y by 4+x into the second equation like this:

7x+5(x+4)=56

⇔ 7x+5(x+4)=56

⇔ 12x+20=56

⇔ x = 3

now using equation (1) we get : y=3+4 = 7

:)

Answer:

96-8k = 3k+63

96 - 11k = 63      

(you get -11 by bringing the +3k to the other side which changes the sign to -3k ;   -8k-3k = 11k)

-11k = 63 - 96

-11k = -33

k = -33/-11

k= 3

Final answer:

In the expression 4(5 + x), the factors are 4 and (5 + x), which can be determined by understanding the distributive property of multiplication over addition.

Explanation:

The question asks, "What are the factors in the expression 4(5 + x)?" To understand this, we need to realize that a factor is something multiplied by another thing that results in a given expression. In this case, the factors of the expression 4(5 + x) are 4 and (5 + x). This is evident from the distributive property of multiplication over addition, which essentially breaks down the expression into its multiplied components. For instance, multiplying 4 by each term inside the parentheses (5 and x) would result in the same expression, 4×5 + 4*x, which shows that 4 and (5 + x) are indeed the factors of the given expression.

Explanation:

Using a calculator,

3/8 = 0.375

The decimal stops and does not go on forever. So it is terminating.

-------

One way to be able to tell that it terminates is to look at the denominator 8, which factors to 2*2*2 or 2^3. The prime factor 2 indicates that the decimal will terminate. The rule is that if the denominator is factored into 2's or 5's only, then the decimal will terminate.

Examples:

1/5 = 0.2,   4/10 = 0.4,   5/8 = 0.625

Some non-examples would be

1/3 = 0.333333...

5/6 = 0.83333....

2/7 = 0.285714...

Each denominator of these non-terminating fractions do not have solely 2's or 5's as part of the factorizations.

Answer:

The number of cows in farmhouse shelter is 16

The number of chickens in farmhouse shelter is 2   .

Step-by-step explanation:

Total number of animals in farmhouse shelters = 18

Total number of legs of both animals = 68 legs

Let The number of cows = C

Let The number of chickens = c

∵  the number of legs does each cow has = 4

And, The number of legs does each chicken has = 2

According to question

∵Total number of animals in farmhouse shelters = 18

i.e number of cows + number of chickens = 18

Or, C + c = 18                       .....1

Again

∵ Total number of legs of both animals = 68 legs

i.e  number of cows × number of legs does each cow has + number of chickens × number of legs does each chicken has = 68

Or, C × 4 + c × 2 = 68

i.e 4 C + 2 c = 68                     ........2

Solving eq 1 and eq 2 , we get

(4 C + 2 c ) - 2 × (C + c) = 68 - 2 × 18

Or, (4 C - 2 C) + (2 c - 2 c) = 68 - 36

Or, 2 C + 0 = 32

∴  C = [tex]\dfrac{32}{2}[/tex]

i.e C = 16

So, The number of cows in farmhouse shelter = C = 16

Again

Put the value of C into eq 1

∵ C + c = 18

Or, c = 18 - C

Or, c = 18 - 16

i.e c = 2

So, The number of chickens in farmhouse shelter = c = 2

Hence, The number of cows in farmhouse shelter is 16 and The number of chickens in farmhouse shelter is 2   . Answer

Step-by-step explanation:

Range = highest value - lowest value

The highest value from the data set given = 1

The lowest value = -4

Therefore :

Range = 1 - (-4)

Range = 1 + 4

Range = 5

Answer:

3 quarters and 7 pennies

Step-by-step explanation:

You can write equations, but you can also use the trial and error method.

Guess 1:

1 quarter = 25 cents

82 - 25 = 57

57 pennies = 57 cents

25 cents + 57 cents = 82 cents

57 - 1 = 56

He has 56 more pennies than quarters, so this is not the answer.

Guess 2:

2 quarters = 50 cents

82 - 50 = 32

32 pennies = 32 cents

50 cents + 32 cents = 82 cents

32 - 2 = 30

He has 30 more pennies than quarters, so this is not the answer.

Guess 2:

3 quarters = 75 cents

82 - 75 = 7

7 pennies = 7 cents

75 cents + 7 cents = 82 cents

7 - 3 = 4

He has 4 more pennies than quarters, so this is the answer.

Answer: 3 quarters and 7 pennies

The boy has 3 quarters and 7 pennies.

To solve this problem, we can set up a system of equations. Let's say that the number of quarters the boy has is q. Since he has 4 more pennies than quarters, the number of pennies he has is q + 4. We know that 1 quarter is equal to 25 cents and 1 penny is equal to 1 cent. So, the total value of the coins can be expressed as 25q + (q + 4) = 82.

Simplifying the equation, we have 25q + q + 4 = 82.

Combining like terms, we get 26q + 4 = 82.

Subtracting 4 from both sides, we have 26q = 78.

Dividing both sides by 26, we find that q = 3. Therefore, the boy has 3 quarters and 3 + 4 = 7 pennies.

The price will increase 8024 dollars.

The price of next model will be $67,024.

Step-by-step explanation:

Given,

Cost of current model = $59,000

Increase in new model = 13.6% of cost of current model

Amount of increase = [tex]\frac{13.6}{100}*59000[/tex]

Amount of increase = 0.136 * 59000

Amount of increase = $8024

The price will increase 8024 dollars.

Cost of next model = Cost of current model + Amount of increase

Cost of next model = 59000 + 8024 = $67,024

The price of next model will be $67,024.

Debra needs 126 cups of fertilizer for her garden.

To solve this problem, we need to follow these steps:

1. Calculate the area of Debra's rectangular garden.

2. Convert the area from square yards to square feet.

3. Determine the total amount of fertilizer needed in cups.

Let's start:

1. Calculate the area of the rectangular garden:

  Length = 9 1/3 yards

  Width = 12 yards

  Area = Length × Width

       = (9 1/3) × 12

  First, let's convert 9 1/3 to an improper fraction:

[tex]\( 9 \frac{1}{3} = \frac{(9 \times 3) + 1}{3} = \frac{27 + 1}{3} = \frac{28}{3} \)[/tex]

  Now, multiply the fractions:

  Area = [tex]\( \frac{28}{3} \times 12 \)[/tex]

       = [tex]\( \frac{28 \times 12}{3} \)[/tex]

       = [tex]\( \frac{336}{3} \)[/tex]

       = 112 square yards

2. Convert the area from square yards to square feet:

  1 square yard = 9 square feet

  Area in square feet = 112 square yards × 9

                      = 1008 square feet

3. Determine the total amount of fertilizer needed in cups:

  Given that 1/8 cup of fertilizer is needed per square foot.

  Total cups of fertilizer = Area in square feet × (1/8)

                           = 1008 × (1/8)

                           = 126 cups

So, Debra needs 126 cups of fertilizer for her garden.

To find the median of Gary's monthly car sales, we arrange the numbers in ascending order and find the average of the two middle numbers since there's an even number of observations. The median number of cars sold is 10.5.

The subject of this question is Mathematics and it pertains to the concept of calculating the median in statistics. Gary's monthly car sales in ascending order were: 5, 9, 10, 11, 12, 14. When calculating the median of a set of numbers, we first put the numbers in order from least to greatest. If there is an odd number of observations, the median is the middle number. If there is an even number of observations, the median is the average of the two middle numbers.

In this case, Gary's sales were an even number of months, so we find the average of the two middle numbers (10 and 11). To calculate the average, we add the two numbers together and then divide by 2: (10+11)/2 = 10.5. So, the median number of cars Gary sold per month is 10.5.

y = -x - 1 is the equation of the line that passes through (2,-3) and is perpendicular to y = x - 5

Solution:

Given that we have to write the equation of the line that passes through (2,-3) and is perpendicular to y = x - 5

The equation of line in slope intercept form is given as:

y = mx + c ------ eqn 1

Where, "m" is the slope of line and "c" is the y intercept

Given equation of line is:

y = x - 5

On comparing the above equation with eqn 1,

m = 1

We know that,

Product of slope of line and slope of line perpendicular to given line is equal to -1

Therefore,

[tex]1 \times \text{ slope of line perpendicular to given line } = -1\\[/tex]

Slope of line perpendicular to given line = -1

Now we have to find the equation of line with slope -1 and passing through (2, -3)

Substitute m = -1 and (x, y) = (2, -3) in eqn 1

-3 = -1(2) + c

-3 = -2 + c

c = -3 + 2

c = -1

Substitute m = -1 and c = - 1 in eqn 1

y = -x - 1

Thus the equation of line is found

Answer:

[tex]\frac{7}{12}[/tex]  of an hour is remaining for Mariko's social studies class

Step-by-step explanation:

Given:

Total duration of Mariko's social studies class = 5/6 of an hour.

Only 3/12 of an hour has passed.

To Find:

Fraction of an hour remains for Mariko's social studies class =?

Solution:

Converting into minutes

5/6 of an hour =  [tex]\frac{5}{6} \times (60)[/tex]

=>[tex]\frac{300}{6}[/tex]

=>50 minutes

So the total duration of  Mariko's social studies = 50 minutes

If  3/12 of an hour passes means

Converting into  minutes

=>[tex]\frac{3}{12} \times 60[/tex]

=>[tex]\frac{180}{12}[/tex]

=>[tex]\frac{180}{12}[/tex]

=> 15 minutes

15 minutes has passed

Remaining time left is

50 minutes - 15 minutes = 35 minutes left

Now converting into 35 minutes into hours we get

=> [tex]\frac{35}{60}[/tex]

=>[tex]\frac{7}{12}[/tex]

Subtracting the time passed from the total class time gives us the remaining time. The calculation involves simplifying the time passed fraction and finding a common denominator to subtract fractions. In the end, we find that 7/12 of an hour remains for Mariko's social studies class.

This is a question about subtracting fractions to calculate remaining time. Mariko's social studies class lasts 5/6 of an hour and 3/12 of an hour has passed. To find out how much time remains, you need to subtract the time that has passed from the total class time.

First, you simplify the fraction of the time that has passed. 3/12 simplifies to 1/4, since 3 and 12 are both divisible by 3.

Then, you subtract 1/4 from 5/6 to calculate the time remaining. To do this, you need to find a common denominator, which is 12 in this case.

Converting 5/6 and 1/4 into twelfths gives you the fractions 10/12 and 3/12 respectively.

Then, subtract 3/12 from 10/12 which is 7/12.

So, the answer is 7/12 of an hour remains for Mariko's social studies class.
