C) two solutions
D) infinitely many solutions
Answer:
A) no solution
Step-by-step explanation:
These lines are parallel. Which means that they will never intersect, and since the solution to a system of equations is the point or points of intersection, this means there would be no solution to this system.

large area: small area = 100:25 = 4:1
Step-by-step explanation:
Mid-Segment of a triangle is always parallel to the third side, and the length of the midsegment is half the length of the third side.
(x₁,y₁) (x₂,y₂) (x₃,y₃): A(-10,30), B(30,50, C(-40,20)
XY = 1/2 AC , YZ = 1/2 AB , ZX = 1/2 BC
X (10,40) , Y (-5,35) , Z (-25,25) : X(x'₁,y'₁), Y(x'₂,y'₂), Z(x'₃,y'₃)
area of triangle by 3 vertices: (x₁,y₁) (x₂,y₂) (x₃,y₃) is
a = abs[x₁(y₂-y₃)+x₂(y₃-y₁)+x₃(y₁-y₂)] / 2 ... this is just a common formula for any triangle
a = abs(-10*30 + 30*-10 + -40*-20) / 2 = 100
a' = abs(10*10 + -5*-15 + -25*5) / 2 = 25
a/a' = 100/25 = 4/1

What is 7/8 divided by 2/8
Answer:
7/8 ÷ 2/8 = 3 1/2
Step-by-step explanation:
When we divide two fractions, such as 7/8 ÷ 2/8, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.
The quotient obtained from the division of given fractions is 7/2.
Given that, 7/8 divided by 2/8.
Dividing fractions is nothing but multiplying the fractions by reversing one of the two fraction numbers or by writing the reciprocal of one of the fractions. By reciprocal we mean, that if a fraction is given as a/b, then the reciprocal of it will b/a.
Here, 7/8 ÷ 2/8
= 7/8 × 8/2
= 7/2
Therefore, the quotient obtained from the division of given fractions is 7/2.

3. Physics students were modeling the height of a ball once it was dropped from the roof of a 25 story
building. The students found that the height in feet, h, of the ball above the ground as a function of the
number of seconds, i, since it was dropped was given by h(t)= 300 - 1612.
From what height was the ball dropped?
To the nearest tenth of a second, determine the time at
which the ball hits the ground. Provide evidence from a
table to support your answer or solve this algebraically
if you recall how to.
It will take 4.3 seconds for the ball to hit the ground
Given the eqation of the height at which the object dropped expressed as
h(t) = 300 - 16t²
The object will hit the ground at when h(t) = 0
Substitute h(t) = 0 into the expression to have;
0 = 300 - 16t²
16t² = 300
t² = 300/16
t² = 18.75
t = 4.33sec
This shows that it will take 4.3 seconds for the ball to hit the ground

2. Which is the BEST definition of a line's x-intercept?
The x-intercept of a line is where the line crosses the y-axis.
The x-intercept of a line is where the line crosses the vertical axis.
The x-intercept of a line is where the line crosses the horizontal axis.
The x-intercept of a line is where the line crosses the origin.
Answer: The best definition is the third option. Hope this helps! Brainliest?
What is the length of BC?
Enter your answer in the box.
(Box) Units
Angle A and B are shown to be the same which means the 2 sides are the same. Using the 2 sides solve for x.
2x -24 = x-2
Add 24 to both sides
2x = x + 22
Subtract x from both sides:
X = 22
Bc = x , so BC = 22
Enter the equation of the line in slope-intercept form.
Slope is -3, and (4,3) is on the line.
The equation of the line is y =
The slope intercept formula y= mx+b .
y= mx+b
We already know the slope which is -3 and plugin 4 for x and 3 for y. Here we are trying to find the y-intercept which is b.
3= -3(4)+b
3= -12+b

for a field trip the school bought 47 sandwiches for $4.60 each and 39 bags of chips for $1.25 each.How much did the school spend in all?
Answer: To get to your final sum you will have to calculate the sum of both items: the sandwiches and the chips. Then you will get the total sum of all what they spend.
Step 1:
Sum of one sandwich= 4.60 dollar
sum of 47 sandwiches= 47×4.60 =216.2dollars
Step 2:
Sum of one chip=1.25 dollar
sum of 39 bags of chips=39×1.25= 48.75dollars
step 3: sum up the sum of sandwiches and that of the chips
216.2 + 48.75 =264.95dollars

A tractor can plant a field at a rate of 2.5 acres per 5 minutes. If a mammoth farm measuring 4 square miles needs planting, how long will it take in hours to plant the field? There are 640 acres in a square mile. Determine your answer to the nearest hour. If the tractor can run 8 hours a day, what is the minimum number of days it will take to plant the farm?
The time taken by the tractor to plant the field with an area of 4 square miles is nearly 85 hours.
The minimum number of days taken by the tractor when working 8 hours a day is 11 days.
What is the area?The area is the total surface occupied within the boundary of the figure.
How to solve the question?In the question, we are given that a tractor can plant a field at a rate of 2.5 acres per 5 minutes.
We are asked the time taken by the tractor to plant a field having an area of 4 square miles.
First, we convert the area of the field from sq. miles to acres using the conversion rate, 1 square mile = 640 acres,
Thus, the area of the field = 4 sq. miles = 4*640 acres = 2560 acres.
Time taken to plant 2.5 acres is given to be 5 minutes.
Thus, the time taken to plan 1 acre = 5/2.5 = 2 minutes.
Thus, the time taken to plant the field having an area of 2560 acres = 2560*2 minutes = 5120 minutes = 85.33 hours = 85 hours and 20 minutes.
Thus, the time taken by the tractor to plant the field with an area of 4 square miles is nearly 85 hours.
The time for which the tractor can run daily is 8 hours.
Thus, the number of days taken by the tractor to plant the field = 85.33/8 = 10.66625, or 11 days.
Thus, the minimum number of days taken by the tractor when working 8 hours a day is 11 days.

Answer:
CD = 30.43; LK = 14.08
Step-by-step explanation:
Problem 12.
Let's first find BD. Triangle ADB is a right triangle with hypotenuse AB. By definition of sine ( or by theorem, they're equivalent) [tex]{BD \over 20} = sin 54.[/tex], hence BD= 16.18. Jump on the other side now. Triangle BDC is a right triangle with sides BD and CD. By definition of tangent [tex] {{16.18} \over CD} = tan 28 [/tex], thus CD= 30.43.
Problem 13
Assuming the 72° is angle JLK
As usual, triangle MJL is a right triangle with sides MJ and LJ. By definition of tangent [tex] {{JL} \over 14} = tan 51 [/tex]. Follows that JL = 14.81. Now, similarly, trinagle JLK is a right triangle, with hypotenuse JL. From the definition of sine, as before,[tex]{KL \over 14.81} = sin 72.[/tex]. Solving for the only unknown value, you find LK = 14.08.
