How many solutions does the following equation have?

Answer: $116,000

Step-by-step explanation:

Set up a ratio and then cross multiply and divide. See paper attached. (:

Final answer:

Ava's salary is calculated based on the given salary ratio of Paul to Ava (3:4). By dividing Paul's salary by 3, we find out how much one part of the ratio is worth and then multiply by 4 to find Ava's salary to be $116,000.

Explanation:

The question provided asks us to calculate Ava's salary based on the ratio of Paul to Ava's salaries which is 3:4. If Paul's salary is $87,000, we determine Ava's salary using the given ratio. Here is the step-by-step process:

Step 1: Understand the ratio, which tells us that for every 3 parts of Paul's salary, Ava gets 4 parts. This does not tell us the total amount, but how they share the total amount.

Step 2: Since Paul's salary is $87,000, and that represents 3 parts of the total, we divide $87,000 by 3 to find out what 1 part is: $87,000 / 3 = $29,000.

Step 3: Now that we know 1 part is $29,000, we can calculate Ava's salary which is 4 parts: $29,000 X 4 = $116,000.

Ava's salary is therefore $116,000.

[tex]p = (0.9801) ^ {30}[/tex]

Step-by-step explanation:

the probability of a jaywalker being hit is

[tex]P = \frac{1}{100} = 0.01[/tex].

So the probability of a jaywalker not being hit is:

[tex]P '= 1-0.01[/tex]

[tex]P '= 0.99[/tex]

As in this experiment the probability of each trial is independent then, the probability that it is not a jaywalker will not be hit if it makes a round trip is:

[tex]P '= (0.99) (0.99) = 0.9801[/tex]

[tex]P '= 0.9801[/tex]

If this experiment is repeated for 30 days then the probability that it is not a jaywalker will not be hit if it makes a round trip is:

[tex]p = (0.9801) ^ {30}[/tex]

Answer:

[tex]y=19.7*10^{3}[/tex]

Step-by-step explanation:

step 1

Find the slope

we know that

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

we have

[tex](-200,-4.03*10^{4}), (50,9.7*10^{3})[/tex]

convert to

[tex](-200,-40.3*10^{3}), (50,9.7*10^{3})[/tex]

substitute in the formula

[tex]m=\frac{9.7*10^{3}+40.3*10^{3}}{50+200}[/tex]

[tex]m=\frac{50*10^{3}}{250}[/tex]

[tex]m=200[/tex]

step 2

Find the equation of the line into point slope form

[tex]y-y1=m(x-x1)[/tex]

we have

[tex](x1,y1)=(50,9.7*10^{3})[/tex]

[tex]m=200[/tex]

substitute

[tex]y-9.7*10^{3}=200(x-50)[/tex] ----> equation of the line into point slope form

step 3

Find the value of y when x=100

substitute in the equation the value of x

[tex]y-9.7*10^{3}=200(100-50)[/tex]

[tex]y=200(50)+9.7*10^{3}[/tex]

[tex]y=19,700[/tex]

[tex]y=19.7*10^{3}[/tex]

Answer:

Step-by-step explanation:

We’ll I find it’s 6 dollars a day and their are 5 days that would be 30 but this went in for 8 weeks so it would be 30 x 8 which equal 240

Answer:

Required expression for amount spend on breakfast for 8 week is ( 6 × 5 ) × 8 and this amount is $ 240

Step-by-step explanation:

Given:

Amount spend on Breakfast using debit card = $6

Amount for breakfast spend for 5 mornings per week for past 8 weeks.

We need to write the multiplication expression for the given situation.

Amount spend on breakfast for a morning = $6

Amount spend on breakfast for 5 morning = 6 × 5

Amount spend on breakfast for 1 week = $ ( 6 × 5 )

Amount spend on breakfast for 8 week = ( 6 × 5 ) × 8

Required multiplication expression = ( 6 × 5 ) × 8

Answer of the multiplication = ( 6 × 5 ) × 8 = ( 30 ) × 8 = 240

Therefore, Required expression for amount spend on breakfast for 8 week is ( 6 × 5 ) × 8 and this amount is $ 240

Answer:

[tex]g(x)=-x^{2}-4[/tex]

Step-by-step explanation:

we know that

The function g(x) is a vertical parabola open downward with vertex at (0,-4)

The equation of a vertical parabola into vertex form is equal to

[tex]y=a(x-h)^{2}+k[/tex]

I assume that g(x) is a reflection of the function f(x) over the line y=-2

so

a=-1 ---> because in the function f(x) the value of a is equal to 1

therefore

[tex]g(x)=-x^{2}-4[/tex]

Answer:

(5y+3)(y-1)

Step-by-step explanation:

5y^2-2y-3

I don't know if you like trial factors or not... but we can try that way

notice we have 5y^2

that can be written as 5y * 1y

Notice at the end we have -3

that can be written as -3*1

So possible answers could be:

(5y-3)(1y+1)   =5y^2+5y-3y-3=5y^2+2y-3

So this was almost right.

If we just switch the signs the - and + there we will have got it

(5y+3)(1y-1)=5y^2-5y+3y-3=5y^2-2y-3 which is good

So the answer is (5y+3)(y-1)

To factor the quadratic equation 5y^2-2y-3 completely, find two numbers that multiply to -15 and add to -2, and use them to rewrite the middle term before factoring by grouping. The factors obtained are (5y - 3)(y + 1).

The given quadratic equation to factor completely is 5y^2-2y-3. To achieve this, we are finding two numbers that multiply to the product of the coefficient of y^2 (which is 5) and the constant term (which is -3), and at the same time add up to the coefficient of the y term (which is -2).

The required pair of numbers is -3 and -1, because (-3)*(1) = -3 (the product of coefficient of y^2 and the constant term) and (-3)+(1) = -2 (the coefficient of the y term).

We rewrite the middle term and then factor by grouping:

Answer:

c is the correct answer

Step-by-step explanation:

the way I study

1- Writing the system of equations:

The price of a cup of coffee is denoted by c while the price of a spaghetti is denoted by s

We are given that:

4 cups of coffee and 6 spaghetti cost $20.5

This means that:

4c + 6s = 20.5 ................> equation 1

We are also given that:

1 cup of coffee and 3 spaghetti cost $8.75

This means that:

c + 3s = 8.75 .................> equation 2

2- Solving the equations using substitution methods:

From equation 2:

c = 8.75 - 3s ................> I

Substitute with I in equation 1 and solve for s as follows:

4c + 6s = 20.5

4(8.75 - 3s) + 6s = 20.5

35 - 12s + 6s = 20.5

35 - 6s = 20.5

6s = 14.5

s = $2.41667

Substitute with s in I to get c:

c = 8.75 - 3s

c = 8.75 - 3(2.41667) = 1.4999 = $1.5

3- getting price for 1 cup of coffee and 1 spaghetti:

c + s = 1.5 + 2.41667 = $3.91667

Answer:

[tex]Z=2.49[/tex] and this Z-score is “unusual.”

Step-by-step explanation:

To calculate the Z score use the following formula

[tex]Z=\frac{x-\mu}{\sigma}[/tex]

Where

μ is the average

[tex]\sigma[/tex] is the standard deviation

x is the data to which we will calculate the z-score

In this case

[tex]\mu = 122.3\\\\\sigma= 18.5\\\\x =168.4[/tex]

So

[tex]Z=\frac{168.4-122.3}{18.5}[/tex]

[tex]Z=2.49[/tex]

A z-score is unusual if [tex]Z> 2[/tex] or [tex]Z < -2[/tex]

Finally

[tex]Z=2.49[/tex] and this Z-score is “unusual.”

Answer: 2.49 unusual

Answer:

the slope intercept form is: y = x+2

Step-by-step explanation:

The general form of point slope form is : y-y₁ = m(x-x₁)

The given equation is: y – 3 = (x – 1)

comparing we get,

m = 1

and solving the equation;

y-3 = x-1

Adding +3 on both sides

y = x-1+3

y=x+2

The general formula of slope-intercept form is : y = mx+b

where m is the slope and b is the y-intercept

so, y = x+2

where m =1 and b=2

so, the slope intercept form is: y = x+2

Answer:

x = 5 ± sqrt(35)

Step-by-step explanation:

X^2 - 10x+ 25 = 35.​

Factor the left hand side.  This is the difference of squares.  a^2 -2ab - b^2 = (a-b)^2  where a = x and b = 5

(x-5) ^2 = 35

Take the square root of each side

sqrt((x-5) ^2) =± sqrt(35)

x-5 = ± sqrt(35)

Add 5 to each side

x-5+5 = 5 ± sqrt(35)

x = 5 ± sqrt(35)

Answer: 72

Step-by-step explanation:

Rewriting input as fractions if necessary:

8/9, 7/8

For the denominators (9, 8) the least common multiple (LCM) is 72.

LCM(9, 8)

Therefore, the least common denominator (LCD) is 72.

Rewriting the original inputs as equivalent fractions with the LCD:

64/72, 63/72

Final answer:

To estimate the product -12 4/9 · 5 7/8, round each number to the nearest whole number and multiply. The estimated product is -72.

Explanation:

To estimate the product -12 4/9 · 5 7/8, we can round each number to the nearest whole number and then multiply.

Rounding -12 4/9 to the nearest whole number gives -12.

Rounding 5 7/8 to the nearest whole number gives 6.

Now, we can multiply -12 and 6: -12 · 6 = -72.

So, the estimated product is -72.

Squares 1 and 2 have the same area because they're both (a+b) on a side.

Each of these squares is covered by four identical right triangle tiles, legs a,b, hypotenuse c.  

In the first picture we see the uncovered part of the square, not covered by triangular tiles, is two squares, area [tex]a^2+b^2[/tex].

In the second picture the uncovered part of the square is a smaller square, area [tex]c^2[/tex].

We just moved the tiles around on the square, so the uncovered part is the same in both cases.  So

[tex]a^2 + b^2 = c^2[/tex]
