grapes are sold for $3.20 per bag. if you have $12, how many bags of grapes can you buy?
Answer:
you can buy 4 bags of grapes with $12.
Step-by-step explanation:
Hope this helps :)
Answer:
Step-by-step explanation:
Since we know that one bag of grapes = $3.20, we can divide $12 by $3.20 to get how many bags of grapes you can buy.
12/3.2=3.75.
In the exact amount, you can buy 3.75 bags of grapes. Now you can't buy .75 of a bag. Rounding it, you would have approximiatly bought 4 bags. Reality, you would have bought 3 bags.

Answer:
The third one
Step-by-step explanation:
two angles in a triangle have measures of 62 degrees and 15 degrees. What is the measure of the third angle.
A.92 degrees
B.47 degrees
C.77 degrees
D.103 degrees
Answer:
the answer is 103
Step-by-step explanation:62°+15°=77° degrees
Then it is 180° - 77° degrees
180°-77°=103°
The measure of the third angle of a given triangle is 103°.
Given that the measure of two angles is 62° and 15°.
We need to find the measure of the third angle.
What is the angle sum property of a triangle?The angle sum property of a triangle states that the sum of interior angles of a triangle is 180°.
Let the measure of the third angle be x.
Now, 62°+15°+x=180°
⇒x=180°-77°
⇒x=103°
Therefore, the measure of the third angle is 103°.

Which of the following equations has a positive slope?
y= -x+0
y= x
y= -4
Answer: i say number 3
Step-by-step explanation:
because i pay attention in math class
The equation y = x has the positive slope.
What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.
Given three equations which are in the form of slope intercept form of the equation of a line.
Slope intercept form of a line is y = mx + d, where m is the value of the slope and d is the value of the y intercept.
y intercept is the y coordinate of the point on the line where it touches the Y axis. The x coordinate will be 0 there.
Equations given are
y = -x + 0 ⇒ Slope = -1
y = x ⇒ Slope = 1
y = -4 ⇒ Slope = 0
So y = x has the slope equal to 1 which is positive.
Hence the equation y = x has the positive slope.
