Answer:
No, they are not equal
Step-by-step explanation:
8 is twice as much as 4 but 9 is not twice as much as 5, therefore they are not equal and 9/5 is smaller than 8/4
May I have brainliest please? :)
Answer:
no they are not equal
Step-by-step explanation: They are not equal because 8/4 is an even number and 9/5 is an odd number

A t-shirt printing company charges a one-time setup fee, plus a charge to print each t-shirt. The math club had 75 t-shirts printed for a cost of $424. The science club had 50 t-shirts printed for a cost of $299. What is the cost of having 170 t-shirts printed? *
Answer:
$826.70
Step-by-step explanation:
If 75 t-shirts cost $ 424, it implies that the value of each shirt is $ 5.65 (424/75). Now, in the case of the 50 shirts, the total value is $ 299, with which the value of each unit is $ 5.98.
Thus, we can see that in an increase of 50% of the units (from 50 to 75), the discount is of the order of, as it arises from the following calculation:
5.98 = 100
5.65 = X
((5.65 x 100) / 5.98) = X
94.48 = X
Thus, since 100 - 94.48 is 5.52, the discount made for the 25 shirts is 0.22% each unit (5.52 / 25). Thus, in the case of printing 170 t-shirts, taking into account this tariff system, and taking as a base price that of 50 t-shirts at $ 299, a discount of 0.22% would be made on each of the 120 remaining t-shirts. Thus, 120 t-shirts at $ 717.6 (5.98 x 120) would be added to the initial $ 299, on which a 26.4% discount (0.22 x 120) would be applied, with which the final price would be $ 527.7 (717 x 0.736).
Thus, the total price of the shirts would be $ 826.7 (that is, adding the base price of $ 299 plus the price of the 120 extra shirts of $ 527.7).
indicate in standard form the equation of the line passing through the given points, in the equation box below. X(0, 6), Y(5, 6)
Answer:
0x + y = 6
Step-by-step explanation:
Equation of the Line
The equation of a line passing through points (x1,y1) and (x2,y2) can be written as follows:
[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
It can be later converted to any other form of the line. For example, the standard form is:
[tex]Ax + By = C[/tex]
Let's find the equation by using the given points (0,6) (5,6):
[tex]\displaystyle y-6=\frac{6-6}{5-0}(x-0)[/tex]
Operating:
[tex]\displaystyle y-6=\frac{0}{5-0}(x-0)[/tex]
y - 6 = 0
Or, equivalently:
0x + y = 6
This corresponds to a horizontal line

What is the axis of symmetry for the following equation?
y=4x2-8x+9
Answer:x=1
Step-by-step explanation:
The x of the top of the parabola is:
x=-(-8)/(2*4)=1
x=1
Using quadratic function concepts, it is found that the axis of symmetry for the function is x = 1.
The standard quadratic function is modeled by:
[tex]y = ax^2 + bx + c[/tex]
And has axis of symmetry given by:
[tex]x = -\frac{b}{2a}[/tex]
In this problem, the function is:
[tex]y = 4x^2 - 8x + 9[/tex]
The coefficients are:
[tex]a = 4, b = -8, c = 9[/tex]
Then, the axis of symmetry is:
[tex]x = -\frac{b}{2a} = -\frac{(-8)}(2(4)} = 1[/tex]

Convert the rate 25 miles per hour to feet per second
Answer:
36.67 feet / second
Step-by-step explanation:We will be using Dimensional Analysis to solve this question
We are given the rate: 25 miles / hour
Converting the Miles to feet:
We know that 1 mile = 5280 feet
So, we can say that [tex]\frac{5280 feet}{1 mile}[/tex] = 1
Multiplying the Given rate by 1:
[tex]\frac{25 miles}{Hour}[/tex] * 1
(multiplying by 1 will not change the actual value of the expression)
[tex]\frac{25 miles}{Hour}[/tex] * [tex]\frac{5280 feet}{1 mile}[/tex] (since 5280 feet/ 1 mile = 1)
here, the 'mile' will cancel out and we will get:
[tex]\frac{25 * 5280 feet }{Hour }[/tex]
[tex]\frac{132000 feet}{Hour}[/tex]
Converting the Hours to Seconds:
We know that 1 hour = 3600 seconds
So, we can say that:
[tex]\frac{1 Hour}{3600 seconds}[/tex] = 1
Multiplying the Rate by 1:
[tex]\frac{132000 feet}{1 Hour} * 1[/tex]
(multiplying by 1 will not change the actual value of the expression)
[tex]\frac{132000 feet}{1 Hour} * \frac{1 Hour}{3600 seconds}[/tex] (since 1 hour / 3600 seconds = 1)
Here, the 'Hour' in the numerator and the denominator will cancel out to make:
[tex]\frac{132000 feet}{3600 seconds}[/tex]
which can be simplified to:
[tex]\frac{36.67 feet}{second}[/tex]
Therefore, 25 mph can also be written as 36.67 feet per second

Answer:
$2,070,000
Step-by-step explanation:
The series of salaries has a first term of $40,000 and a common difference of $2,000. The sum of them is given by the formula ...
Sn = (2a1 +d(n -1))(n/2)
where a1 is the first term of the series, d is the common difference, and n is the number of terms.
In this problem, we have ...
a1 = 40,000; d = 2,000; n = 30
so the sum is ...
S30 = (2(40,000) +2,000(30 -1))(30/2) = (80,000 +58,000)(15)
S30 = 2,070,000
The teacher will earn $2,070,000 over 30 years on this salary schedule.

find the equation of the line shown
Answer:
y = x + 1
Step-by-step explanation:
find slope (y2-y1)/(x2-x1)
pick 2 points (0,1) and (1,2)
(2-1)/(1-0) = 1/1 = 1
Since (0,1) you know that y intercept is 1
the equation in slope intercept form: y = x + 1

2. The mean birth weight of a full term boy born in the US is 7.7 lbs, with standard deviation of 1.1 lbs. A. Find the probability that a boy born full term in the US weighs less than 7 lbs. B. Find the probability that the average weight of 25 baby boys born in a particular hospital have an average weight less than 7 lbs.
Answer:
A
The value is [tex]P( X < 7 ) =0.26226[/tex]
B
The value is [tex]P( X < 7 ) = 0.00073[/tex]
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 7.7 lbs[/tex]
The standard deviation is [tex]\sigma = 1.1 \ lbs[/tex]
The sample size is n = 25
Generally the probability that a boy born full term in the US weighs less than 7 lbs is mathematically represented as
[tex]P( X < 7 ) = P( \frac{X - \mu }{\sigma} < \frac{7 - 7.7 }{1.1 } )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
=> [tex]P( X < 7 ) = P(Z <- 0.6364 )[/tex]
From the z table the area under the normal curve to the left corresponding to -0.6364 is
[tex]P(Z <- 0.6364 ) =0.26226[/tex]
=> [tex]P( X < 7 ) =0.26226[/tex]
Generally the standard error of mean is mathematically represented as
[tex]\sigma_{x} = \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]\sigma_{x} = \frac{ 1.1 }{\sqrt{25} }[/tex]
=> [tex]\sigma_{x} = 0.22[/tex]
Generally the probability that the average weight of 25 baby boys born in a particular hospital have an average weight less than 7 lbs is mathematically represented as
[tex]P( \= X < 7 ) = P( \frac{\= X - \mu }{\sigma_{x}} < \frac{7 - 7.7 }{ 0.22 } )[/tex]
=> [tex]P( X < 7 ) = P(Z <- 3.1818 )[/tex]
From the z table the area under the normal curve to the left corresponding to -3.1818 is
=> [tex]P(Z <- 3.1818 ) = 0.00073[/tex]
=> [tex]P( X < 7 ) = 0.00073[/tex]

A garden is in the shape of a rectangle 90 m by 60 m.
Flowers are grown in 40% of the garden.
The rest of the garden is grass.
Work out the area of the garden that is grass.
Answer:
3240 sq meters
Step-by-step explanation:
Area of garden = 90*60= 5400 square meters.
Flowers grown on = 40%
So, grass grown on = (100 -40)% = 60%
60% of 5400 = 0.6*5400 = 3,240.
So, the area of the garden that is grass = 3,240 square meters
