Step-by-step explanation:
Aron charges an initial service fee of 10$ plus 15$ per hour , what is X?
Answer:
The linear function becomes:
y = 15x + 10
Here, 'x' is the number of hours, b=10 is the initial service fee i.e. $10, 15 is slope or rate of change, and 'y' is the cost.
Step-by-step explanation:
We know that the slope-intercept of a linear function is
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
Note: Slope is also termed as the 'rate of change'.
Given that Aron charges an initial service fee of 10$.
Thus, the y-intercept = b = 10
As the rate of change = 15$ per hour
so the slope = m = 15
Therefore, the linear function becomes:
[tex]y = mx+b[/tex]
y = 15x + 10
Here, 'x' is the number of hours, b=10 is the initial service fee i.e. $10, 15 is slope or rate of change, and 'y' is the cost.
For example, in one hour i.e. x = 1, the cost 'y' will be:
y = 15x + 10
y = 15(1) + 10
y = 25 + 10
y = $25
Therefore, in one hour (x=1), the cost will be: y = $25

A triangle formed by the sides 3.8cm ,3.7 cm, and 5cm is
By the Pythagoras theorem we know that the if the square of the longest side of the triangle is equal to the sum of the square of other two sides.
The triangle formed by the sides 3.8 cm ,3.7 cm, and 5 cm is acute angle triangle.
How to find the type of triangle?
By the Pythagoras theorem we know that the if the square of the longest side of the triangle is equal to the sum of the square of other two sides. Thus,
For a triangle to be right angle triangle,[tex]c^2=a^2+b^2[/tex]
By this law it is observed that,
For a triangle to be acute angle triangle,[tex]c^2<(a^2+b^2)[/tex]
For a triangle to be obtuse angle triangle,[tex]c^2>(a^2+b^2)[/tex]
The sides of the given triangle are 3.8 cm ,3.7 cm, and 5 cm.
Here the longest side is 5 cm. Thus check the type of triangle using above formula. Longest side,
[tex]c^2=5^2\\c^2=25[/tex]
Other two sides,
[tex]a^2+b^2=3.8^2+3.7^2\\a^2+b^2=14.44+13.69\\a^2+b^2=28.13[/tex]
Therefore,
[tex]25<28.13\\[/tex]
Hence the triangle formed by the sides 3.8 cm ,3.7 cm, and 5 cm is acute angle triangle.

Pete wants to mix 4 quarts of 20% orange juice concentrate with some 60% pineapple juice concentrate to get a 50% punch concentrate for a party. How much of the 60% pineapple juice concentrate should be used? please answer ASAP and explain thought process
Answer:
12 quartsStep-by-step explanation:
Let the amount of pineapple juice be x quarts, the concentration of juice is as following equation:
4*0.2 + x*0.6 = (4 + x)*0.50.8 + 0.6x = 2 + 0.5x0.6x - 0.5x = 2 - 0.80.1x = 1.2x = 128. Syairra needs to take an Uber to get to
the airport. The Uber charges $5.00 for
the first mile, and then $3.00 for each mile
after that. If the total charge is $62.00,
then how far was Syairra's taxi ride to the
airport?
Answer: 20 miles
Step-by-step explanation:
Since the Uber charges $5.00 for the first mile you have to subtract that from the total which is 62.
62.00 - 5.00 = 57.00
Then you keep subtracting 3.00 from 57.00 or you can divide 57 by 3 because 57 is how much money is left and the Uber charges 3 dollars for each mile after the first.
57.00 divided by 3.00 is 19
Then add 1 to 19 which equals 20 miles. You add 1 to 19 because 19 is the amount of miles she goes but that doesn’t include the 1st mile.

A set of stickers contains 4 hearts for every 6 stars. Which choice contains an equivalent ratio of hearts to stars? A. 6 hearts to 9 stars B. 8 hearts to 10 stars C. 1 heart to 3 stars D. 2 hearts to 4 stars
Answer:
6 hearts to 9 stars
Step-by-step explanation:
If a set of stickers contains 4 hearts for every 6 stars, this means that
4 hearts = 6stars
1 heart = x
Cross multiply
4x = 1*6
4x = 6
x = 6/4
x = 3/2
Number of hearts = 3/2 * 4 = 3*2 = 6
Number of stars = 3/2 * 6 = 3 * 3 = 9
Hence equivalent ratio of hearts to stars is 6 hearts to 9 stars
Answer:
6 to 9

Answer:
D) L+S=9 ; 6L+3S=9
Step-by-step explanation:
Given this information, we know that the total number of large and small Ubers must be 9, so we can eliminate choices A and C as the first part of the system of equations is L+S=9
Also, since the large Ubers can fit only 6 people per vehicle and the small Ubers can only fit 3 people per vehicle, then we can eliminate choice B as the second part of the system of equations is 6L+3S=39
Therefore, the only correct choice is D

1,3, and 4 are isometric because they preserve the size of the shape. 2 is not an isometry because the size of the shape changes.
Step-by-step explanation:
To find the translation in the first 2 questions, you would first choose a reference point on the original shape (like point S). Then, you count the number of units it moved in the x-direction (to the right 2) which is the x coordinate. Then, you count the number of spaces it moved in the y-direction (down 1) which corresponds to the y coordinate -1.

find an equation for line L
Explanation:
Line L is the horizontal line. Any point on this line has y coordinate y = 4, so the equation is simply y = 4.
You could say the equation is y = 0x+4, which shows the slope is 0. But I think y = 4 is the better answer.
