Answer:

3x - y + 7 = 0

Step-by-step explanation:

The given point is , ( -4 , -5) and the slope is 3. The point slope form is ,

=> y - y₁ = m( x - x₁)

=> y - (-5) = 3 { x - (-4) }

=> y +5 = 3( x + 4 )

=> y + 5 = 3x + 12

=> 3x - y + 12 - 5 = 0

=> 3x - y +7 = 0

Step-by-step explanation:

The amount cheaper is the car washes Malcolm orders than the car washes Martha's order is $13.

The correct answer choice is option B.

Malcolm's gift card = $50.

Cost Malcolm's car wash per visit = $7

Martha's gift card = $180

Cost Martha's car wash per visit = Difference between gift card balance of first and second visit

= $180 - $160

= $20

How cheap is the car washes Malcolm orders than the car washes Martha's order = $20 - $7

= $13

Therefore, Malcolm's car wash is cheaper than Martha's car wash by $13

The weight of a 35.01-carat diamond in grams and ounces

Information given in the question include

1 carat = 0.2 gram,

1 carat = 3.086 grains,

1 ounce = 437.5 grains.

The conversion of the weight units using the given variables can bbe done as follows

1 carat = 0.2 gram

35.01-carat diamond = ?

cross multiplying gives

1 * ? = 35.01 * 0.2

? = 7.002gram

1 carat = 3.086 grains

35.01-carat diamond = ?

cross multiplying gives

1 * ? = 35.01 * 3.086

? = 108.041 grains

That is 35.01-carat diamond = 108.041 grains

1 ounce = 437.5 grains

? = 108.041 grains

cross multiplying gives

437.5 * ? = 108.041 * 1

? = 108.041 /437.5

The required length of the base of the triangular pane of glass is 22 inches.

We know that the formula for the area of a triangle is:

Area = 1/2 * base * height

We are given that the height of the triangular pane of glass is 32 inches and the area is 352 square inches. Substituting these values into the formula, we get:

352 = 1/2 * base * 32

Multiplying both sides by 2 and dividing by 32, we get:

base = 22

Therefore, the length of the base of the triangular pane of glass is 22 inches.

Answer:

6,25,250

Step-by-step explanation:

let initaial population be "x"

after increasing by 2%

x'=x+x*2%

x'=102x/100

x' is decreased by 2% and population reached 625000,so,

625000=102x/100-2%*102x/100

625000=102x/100-51x/2500

625000=2499x/2500

2499x=625000*2500

x=1562500000/2499

x=625250.1

complete population is only counted so,

x=625250

Step-by-step explanation:

Natalie will pay her parents $9 each week, and the initial amount she still owed was $180.

We can see that Natalie is reducing the amount she owes by $18 every two weeks.

Therefore, the amount she owes after 2 weeks is $180 - $18 = $162, after 4 weeks is $144, after 6 weeks is $126, and after 8 weeks is $108.

This means that after n weeks, the amount she still owes is:

$180 - $18n

Since she will pay the same amount each week, let's call the weekly payment P. After one week, she will owe:

$180 - P

After two weeks, she will owe:

($180 - P) - P = $180 - 2P

After four weeks, she will owe:

($180 - 2P) - P - P = $180 - 4P

After six weeks, she will owe:

($180 - 4P) - P - P = $180 - 6P

And after eight weeks, she will owe:

($180 - 6P) - P - P = $180 - 8P

We can set up an equation using the information we have:

$180 - 8P = $108

Solving for P, we get:

P = $9

Therefore, Natalie will pay her parents $9 each week, and the initial amount she still owed was $180.

The algorithm/abstract strategy to justify the fraction 3/5 involves interpreting it as a division, performing the division, and obtaining the decimal representation as the results.

To justify the fraction 3/5, we can use the concept of division and understand it as a ratio or proportion.

Algorithm/Abstract Strategy:

Start with the numerator, which is 3.

Identify the denominator, which is 5.

Interpret the fraction as a ratio or comparison between the numerator and denominator.

Understand that 3/5 represents a division where the numerator (3) is divided by the denominator (5).

Perform the division: 3 ÷ 5.

Simplify the division to its simplest form, if necessary.

The result of the division, in this case, is the decimal representation of the fraction.

If required, convert the decimal representation to a percentage or any other desired form.

For example, if we perform the division 3 ÷ 5, the result is 0.6.

So, 3/5 can be justified as the ratio or proportion where the numerator (3) is divided by the denominator (5) resulting in 0.6.

Answer:

Milan used \(\frac{3}{8}\) more yards of yellow fabric than green fabric.

Step-by-step explanation:

The goal is to subtract 1/4 from 5/8.

\(\frac{5}{8}-\frac{1}{4}\)          This is your original equation. To subtract, the fractions must

                 have common denominators (the same number on the bottom.

                  Therefore, you must find the LCM (least common multiple) of 4

                  and 8, which is 8. Convert 1/4 to 2/8 by multiplying the

                  numerator and denominator by 2.

\(\frac{5}{8}-\frac{2}{8}\)            Now, subtract the numerators. 5-2=3. Leave the denominator.

\(\frac{3}{8}\)

Answer:

\( \sqrt[3]{432 {x}^{5} } \\ \\ 432 = 6 \times 6 \times 6 \times 2 = {6}^{3} \times 2 \\ {x}^{5} = x \times x \times x \times x \times x = {x}^{3} \times {x}^{2} \\ \\ \sqrt[3]{432 {x}^{5} } = 6x \sqrt[3]{2 {x}^{2} } \)

The probability of randomly selecting a male student and female student are non-smokers is 0.6771

What is probability?

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

Probability = (Number of possible outcomes)/(Total number of outcomes)

According to the given question:

Number of male students are smokers = 61

Number of male students are non smokers = 549

Total number of male students = 610

Number of female students are smokers = 156

Number of female students are non smokers = 444

Total number of female students = 600

Probability that both are non smokers is given by

P (non-smoker males) x P (non-smoker females)

= \(\frac{549}{610} . \frac{444}{600}\)

= 0.915 x 0.74

= 0.6771

Therefore the probability that both male and female are non-smokers is 0.6771.
