Arianna's little brother loves playing with bouncy balls. For his birthday, Arianna buys him 3 bouncy balls for $0.65 each. She hands the cashier a five-dollar bill. How much change should Arianna receive?
Answer:
Arianna should receive $3.05 in change.
Step-by-step explanation:
In order to find the answer, you have to find the cost of the three balls by multiplying the cost per ball for the number of balls and then, you have to subtract this amount from five to find the change Arianna should receive:
$0.65*3=$1.95
$5-$1.95=$3.05
According to this, the answer is that Arianna should receive $3.05 in change.

Combine
8x+12=28
Isolate
8x=16
Isolate
x=2
Substitute
4(2+3)=20
4*2=8
Now find each side

Answer:
The coordinates of point B are: (29,-15)
Option D is correct option.
Step-by-step explanation:
Endpoint of diameter of a circle = A(5,7)
Centre of circle = P(17,-4)
We need to find coordinates of other endpoint of diameter of a circle i.e. B
The formula used is: [tex]Midpoint=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]
We are given coordinates of centre (midpoint) P(17,-4)
and A (5,7) x₁=5, y₁=7
We need to find Point B i.e. (x₂,y₂)
Putting values and finding point B
[tex]Midpoint=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})\\(17,-4)=(\frac{5+x_2}{2}, \frac{7+y_2}{2})\\We\:can\:write:\\17=\frac{5+x_2}{2}\:and\: -4=\frac{7+y_2}{2}\\17\times 2=5+x_2\:and\: -4\times 2=7+y_2\\34=5+x_2\:and\: -8=7+y_2\\34-5=x_2\:and\: -8-7=y_2\\x_2=29\:and\: y_2=-15[/tex]
so, we get: x₂ = 29 ,y₂ = -15
The coordinates of point B are: (29,-15)
Option D is correct option.

Answer:
A scale factor of 4in to 5in should be used
Step-by-step explanation:
Given
[tex]Original\ Measurement = 4.5\ in[/tex]
[tex]Scale\ Measurement = 3.6\ in[/tex]
Required
Determine the scale to use
The scale to use can be represented as:
[tex]Scale = Scale\ Measurement : Original\ Measurement[/tex]
This gives:
[tex]Scale = 3.6\ in : 4.5\ in[/tex]
Divide by 0.9
[tex]Scale = \frac{3.6}{0.9}\ in : \frac{4.5}{0..9}\ in[/tex]
[tex]Scale = \frac{3.6}{0.9} : \frac{4.5}{0.9}[/tex]
[tex]Scale = 4 : 5[/tex]
Every summer, Ronald makes cranberry-pear jam with the fruit he collects from his garden. Last summer, he used 3 cups of cranberries and 5 cups of pears to make his jam. This summer, Ronald decided to make an even larger batch using 5 cups of cranberries and 8 cups of pears. Which batch of jam tasted more like cranberries?
Answer:
The batch of jam from this summer
Step-by-step explanation:
Every summer, Ronald makes cranberry-pear jam with the fruit he collects from his garden.
For last summer
Last summer, he used 3 cups of cranberries and 5 cups of pears to make his jam.
Hence,
5 cup of pears = 3 cups of cranberries
1 cup of pears = x
Cross Multiply
5x = 3
x = 3/5
x = 0.6
1 cup of pears = 0.6 cup of cranberries
For this summer
This summer, Ronald decided to make an even larger batch using 5 cups of cranberries and 8 cups of pears.
Hence,
8 cup of pears = 5 cups of cranberries
1 cup of pears = x
Cross Multiply
8x = 5
x = 5/8
x = 0.625
1 cup of pears = 0.625 cup of cranberries
From the above calculation we can see that the quantity of cranberries to 1 cup of pears from this summer is higher than that of last summer
Therefore, the batch of jam that tasted more like cranberries is the batch of jam from this summer
Answer:
This summer’s batch jam tasted more like cranberries.

Expression is a set of numbers, variables, and mathematical operations. The standard form of the expression (-7x+5)-(2x²–8x+6) is -2x²+x-1.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
As the expression is given to us (-7x + 5) - (2x² – 8x + 6), in order to simplify the problem we need to open the brackets. therefore, the expression can be solved as,
[tex](-7x + 5) - (2x^2 - 8x + 6)\\\\= -7x + 5 - 2x^2 + 8x - 6\\\\ = -2x^2+8x-7x-6+5\\\\=-2x^2 + x - 1[/tex]
Hence, the standard form of the expression (-7x+5)-(2x²–8x+6) is -2x²+x-1.
