raises the price of a basketball from $16.80
to $18.90. What is the percent of change?
Answers
Answer:
12.5%
Step-by-step explanation:
% of change = the difference between the new price and the old price ÷ the old price × 100
=> % of change = (18.9 - 16.8) ÷ 16.8 × 100 = 12.5
=> The ans will be 12.5%
Find the 2nd of three consecutive positive even integers such that the product o the second and third integers is twenty more than ten times the first integer.
Answers
Answer:
10
Step-by-step explanation:
Let the three consecutive positive even integers be x-1, x and x+1
First = x-1
Second = x
Third = x+1
If the product of the second and third integers is twenty more than ten times the first integer, then;
x(x+1) = 20 + 10(x-1)
Open the bracket
x² + x = 20 + 10x - 10
x² + x = 10x + 10
x² + x - 10x - 10 = 0
x² - 9x - 10 = 0
x² -10x + x - 10 = 0
x(x-10)+ 1(x-10) = 0
(x+1)(x-10) = 0
x+1 = 0 and x-10 = 0
x = -1 and 10
Hence the 2nd of three consecutive positive even integers is 10

Create an equation that models the total number of calories Jonathan consumes,y,based on number of biscuits he eats,x,and the 6 packages of pemmican
Answers
An equation that models the considered calorie consumption by Jonathan is y = mx + 6k, where m is the number of calorie per buiscuit, and k is the number of calorie per package of pemmican.
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
We're specified that:
x = number of buiscuits Jonathan eastsy = number of calories Jonathan consumes6 = number of packages of pemmican that jonathan consumes.Let we take:
m = number of calories per buiscuit that Jonathan eats.
Then, for x buiscuits, it would be [tex]m \times x[/tex] calories, or in short [tex]mx[/tex] calories.
Let k = number of calories per package of pemmican, then:
for 6 packages of pemmican, it would be [tex]6 \times k[/tex] calories, or in short [tex]6k[/tex] calories.
Thus, total calories Jonathan consumes = y = calories from x buiscuits + calories from 6 packages of pemmican.
or, we get:
[tex]y = mx + 6k[/tex]
Thus, an equation that models the considered calorie consumption by Jonathan is y = mx + 6k, where m is the number of calorie per buiscuit, and k is the number of calorie per package of pemmican.

B.
The graph of his the graph of g vertically shifted up 7 units.
OC.
The graph of his the graph of ghorizontally shifted left 7 units.
The graph of his the graph of g vertically shifted down 7 units.
Answers
Answer:
Step-by-step explanation:
If the function is transformed to obtain the function , then a transformation that affects the x-variable has taken place.
Recall that a transformation that adds t units to the variable "x" represent graphically the horizontal displacement of the original function,"t" units to the left.
Therefore, the correct answer is:
"The graph of his the graph of g horizontally shifted left 7 units."
which agrees with option "B" in your given list.

Ali and Omar cycle around a cycle track.
Ali cycles each lap in 50 seconds.
Omar cycles each lap in 80 seconds.
Ali and Omar start cycling at the same time at the start line.
Work out how many laps they will each have cycled when they are next at the start line together
Answers
Answer and step-by-step explanation:
First, we will have to know at what time they will cross the line at the same time. So we can do the equation:
50 * 80 = 400
That means in 400 seconds they will be level again. Now, let's find Ali's amount of laps for 400 seconds, if it takes Ali 50 seconds for one lap. We can do:
400/50 = 8
This means it will take Ali 8 seconds to be leveled with Omar. Now Omar has the equation:
400/80 = 5
Because it takes him 80 seconds to take one lap. Therefore, it will take Ali 8 laps, and Omar 5 laps to be at the same starting line. Hope this helps!

y = 2x + 17
X – 9y = -17
Answers
Answer:
x = -8
y = 1
Step-by-step explanation:
y = 2x + 17
x – 9y = -17
y = 2x + 17
-9y = -x - 17 (Multiply by 2)
y = 2x + 17
-18y = -2x - 34
-17y = -17
y = 1
y = 2x + 17
1 = 2x + 17
2x = 1 - 17
2x = -16
x = -8

y = x + 9
D. x + 2y = 10
-4x - y = 2
Answers
Answer:
D
Step-by-step explanation:
X+2y=10
-4x-y=2
first, isolate x in first equation: x=10-2y
substitute value of x in first equation (10-2y) into second equation:
-4(10-2y)-y=2
-40+8y-y=2
7y=42
y=6
put value of y (6) into either equation to solve for x
x+2(6}=10
x+12=10
x=-2
x=-2, y=6
prove by inserting x and y values into either equation
-4x-y=2
-4(-2)-6=2
8-6=2
2=2
or
x+2y=10
-2+2(6)=10
-2+12=10
10=10
