The classrooms in the Oakhurst School District are painted every summer. Seven gallons of paint are needed to paint 3 classrooms. How many more gallons are need to paint the 129 classrooms at North High School than the 48 classrooms at Edgewater Elementary?
Answer:
189 gallons
Step-by-step explanation:
7 gallons for 3 classrooms, so 7/3 for 1 classroom
multiply 7/3 * 129 to get 301 gallons at North High School
multiply 7/3 * 48 to get 112 gallons at Edgewater Elementary
301 - 112 = 189 gallons more at North High School than at Edgewater Elementary
The more gallons should be 189 gallons
The calculation is as follows:
7 gallons for 3 classrooms, so 7 by 3 for 1 classroom
Now
we have to multiply 7 by 3 with 129 so that 301 gallons at North High School could come
Now
multiply 7 by 3 with 48 to get 112 gallons at Edgewater Elementary
Now
= 301 - 112
= 189 gallons more

Is y=x+3.75 proportional
Answer:
NO
Step-by-step explanation:
if we plug in 1 = x, we get 4.75 = y. If this is proportional, then y/x will be the same in each scenario.
Let's plug in 2 = x to get y = 5.75. 5.75/2 = 2.875 DOES NOT EQUAL 4.75/1 = 4.75.
That means that the relationship is NOT proportional.
The easier way to tell is to see that there is a number being added, so it can't be a proportional relationship.
Hope this helps and pls do mark me brainliest if you can:)
Answer: No
Step-by-step explanation:
The equal y=x+3.75 is expressed in slope intercept form meaning it doesn't fit the proportional equation which is y=kx and k is the slope.
Because of the y-intercept of the line it makes it not proportional .

As OP bisects ∠AOR, ∠AOP = ∠POR = 55°
So, ∠AOR = ∠AOP + ∠POR = 55° + 55° = 110°
As OS bisects ∠ROB, ∠ROS = ∠SOB = x
As total angle on a line is 180°,
110° + x + x = 180°
=> 2x = 70
=> x = 35°
∠POS = ∠POR + ∠ROS = 55° + x = 55° + 35°
=> ∠POS = 90°

1.5x + 4.5y = 18. Where does the graph intersect the y-axis?
Answer:
4
Step-by-step explanation:
Substitute x for 0 and solve.
1.5(0)+4.5y=18
4.5y=18
y=4
For the equation, 1.5x + 4.5y = 18 at x = 0 the graph will intersect at 4 of y -the axis.
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that the equation is 1.5x + 4.5y = 18. For the value of y substitute x for 0 and solve.
1.5x + 4.5y = 18
1.5(0)+4.5y=18
4.5y=18
y=4
The value of y is equal to 4 means that the graph will intersect the y-axis at 4.

Answer:
The first missionStep-by-step explanation:
The depth readings are
The first mission: - 2 3/4 fathomsThe second mission: - 2 5/8 fathomsComparing the readings
- 2 3/4 = - 2 6/8 and - 2 5/8Absolute values compared

Can someone help me!! what is the smallest positive counterclockwise roation if the point is rotated at 272 degrees clockwise
Given:
The point is rotated at 272 degrees clockwise.
To find:
The smallest positive counterclockwise rotation for the given clockwise rotation.
Step-by-step explanation:
Clockwise rotation = 272°
We need to subtract the given clockwise rotation from 360° to get the smallest positive counterclockwise rotation, because one complete circle is 360°.
Counterclockwise rotation = 360° - Clockwise rotation
= 360° - 272°
= 88°
Therefore, the smallest positive counterclockwise rotation is 88°.
Which statements below are TRUE about perpendicular lines? I. Perpendicular lines intersect II. Perpendicular lines create right angles III. Perpendicular lines are collinear IV. Perpendicular lines never intersect V. Perpendicular lines are coplanar
Answer:
Step-by-step explanation:
Two lines are perpendicular to each other if they both intersects and the two lines are inclined at angle 90°
Since they are inclined at 90° to each other, hence they create right angles.
The lines can also lines on the same plane to form a right angles. This are called coplanar lines.
From the above explanation, the following are true;
I) Perpendicular lines intersect
II) Perpendicular lines create right angles
V) Perpendicular lines are coplanar
They are not collinear because they can't lie on the same straight line. Collinear lines are known to lie on the same straight line.
Hana rents a car for a day. Her car rental company charges $50 per day and $0.40 per mile. Peter rents a car from a different company that charges $70 per day and $0.30 per mile. How many miles do they have to drive before Hana and Peter pay the same price for the rental for the same number of miles?
50 + .4x = 70 + .3x
.4x = .3x + 20
.1x = 20
x = 200
Let x be the number of miles.
They have to drive 200 miles.
They will drive 200 miles before paying same amount.
Let the number of miles that they will drive together and pay the same amount be represented by x.
Since Hana's car rental company charges $50 per day and then $0.40 per mile, this can be represented as:
= 50 + (0.40 × x)
= 50 + 0.40x
Since Peter rents a car from a different company that charges $70 per day and then $0.30 per mile, this will be:
= 70 + (0.30 × x)
= 70 + 0.30x
Then we will equate both Hana's and Peter's equation together and this will be:
50 + 0.40x = 70 + 0.30x
Collect like terms
0.40x - 0.30x = 70 - 50
0.1x = 20
x = 20/0.1
x = 200
In conclusion, they will drive 200 miles before paying thesame amount
