Answer:
7 min : 24 min
Step-by-step explanation:
Convert 2 hours into minutes (it's easier when the units are the same)
35 min : 120 min
Both have a high common factor of 5
Divide both sides by 5
35/5 : 120/5
7 min : 24 min

in what quadrant can you find the point (-5,4)
Answer:
Quadrant II
General Formulas and Concepts:
The top right square of the Cartesian Plane is the First Quadrant.
The top left square of the Cartesian Plane is the Second Quadrant.
The bottom left square of the Cartesian Plane is the Third Quadrant.
The bottom right square of the Cartesian Plane is the Fourth Quadrant.
Read the Cartesian Plane counterclockwise starting from the top right.
Step-by-step explanation:
Step 1: Define
(-5, 4)
x = -5
y = 4
Step 2: Find
We know since x = -5, our point is either going to be in Quadrant II or IIISince y is positive (4), it will go up, meaning that the point will be in Quadrant IIMary sells lemonade, and she sells 10 cents from ever cup she sells to charity. The cups of lemonade are 45 cents. One day she made $17.10. How much money did she to charity that day.
Answer:
$3.80
Step-by-step explanation:
Given that:
One cup of lemonade is sold at 45 cents.
Total money made = $17.10
Number of cups of lemonade sold can be found by dividing the total money made with the sale price of one cup of lemonade.
Number of cups of lemonade sold = [tex]\frac{\$18.10}{45\ cents} = \frac{\$18.10}{\$0.45} =38[/tex]
For each cup sold, 10 cents are donated.
Total money donated = 38 [tex]\times[/tex] 10 = 380 cents = $3.80
Therefore, the answer is:
Total money donated by Mary is $3.80

Si al triple del cuadrado de un número se le suma siete veces el mismo número se obtiene por resultado 10. ¿Cuál es ese número?
Answer:
The value of the number is either 1 or -10/3
Step-by-step explanation:
If the same number is added to triple the square of a number seven times, the result is 10. What is that number?
Let the number = x
Therefore, we have;
3·x² + 7·x = 10
Therefore, we have;
3·x² + 7·x - 10 = 0
Dividing by 3 gives;
x² + 7/3·x - 10/3 = 0
Factorizing gives;
(x - 1)·(x + 10/3) = 0
x = 1 or -10/3
The number is either 1 or -10/3.

Find the values of x and y.
A. x = 129, y = 51
B. x = 51, y = 129
C. x = 66, y = 17
D. x = 17, y = 66
Answer:
C
Step-by-step explanation:
129=2x-3
132=2x
x=66
129+3y=180
180-129=3y
51=3y
y=17
y=x^2-8 is linear or nonlinear
Answer:
Nonlinear.
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
We notice that if the line is linear, x will NOT go over a degree of 1.
x² is a quadratic function, and its slope is not proportional like a linear line.
I NEED THE ANSWER PLEASE
Answer:
Not a function because some x values have multiple y values
Step-by-step explanation:
The meaning of a function is that an x value can only have on y value. If we were to pass a vertical line through this graph, we would find that about 2 points would be hit every time. This tells us that the x values have multiple y values and it's not a function.
