Answers
Answer:
( 9, -35 )
Step-by-step explanation:
We can figure out how far the midpoint is from point A and just add the same values to the midpoint's coordinates to get the location of point B.
From A to Midpoint in the X direction:
+ 6
From A to Midpoint in the Y direction:
-15
The coordinate of the midpoint is:
( 3, -20)
3 + 6 = 9
-15 + (-20) = -35
The coordinates of B are:
( 9, -35 )

Actual distance between two places is 130 miles. The scale of the map is
1 in:100 miles. What is the distance between these two places in the map?
Answers
Answer:
1.3 inches
Step-by-step explanation:
1. Determine what you already know in order to set up the equation:
1 inch = 100 miles
x inches = 130 miles
Solving for x
2. Set up the equation so both numerators are the same unit (In this case, both numerators are the mile values and both denominators are the inch values.)
[tex]\frac{100}{1}[/tex] = [tex]\frac{130}{x}[/tex]
3. Cross multiply (Multiply the first fraction's numerator by the second fraction's denominator, and vice versa. It doesn't matter which number is on which side of the = sign.)
100x = 130
4. Divide each side by 100 to isolate the variable.
x = 1.3
find the equation of straight line passing through the points (a,0) and (0,b). If the point (1,1) lies on the equation, prove that
1/a + 1/b =1
Answers
Answer:
do the following
Step-by-step explanation:
the question says that the line is passing thur the point 1,1 ... so when x = 1 so does y ... also when x= a.. then y=0 and when y=b then x =0 .. and this is a straight line... also 1/a + 1/b = 1
if you were to draw on a graph... this .. you would see that when b=2 then x=0 and also when a=2.. then y = 0 ....
and 1/2 + 1/2 =1
so that's the line.... draw in just roughly.... you'll see... then what is the equation of that line.. usually we would use the slope intercept formula for the equations.. there are more than one way to show the line.. is my point.. but.. if we use y = mx + b where m = -1 and b = 2 then...
y= - x+2
That answer got long.. sorry :/
Answer:
step by step
Step-by-step explanation:
Line passing (a,0) (0,b)
slope = (y2 - y1) / (x2 - x1) = - b/a
pass (0,b), y interception: b
Line: y = -b/a * x + b
pass(1,1) y=1, x=1
1 = -b/a + b
1/b = (-b/a) /b + b/b
1/b = -1/a + 1
1/a + 1/b = 1

The second angle of a triangle is 3 times as large as the first angle. The third angle is 30 degrees more than the first angle. Find the measure of the angles.
Answers
Answer:
30-60-90 degrees
Step-by-step explanation:
1st angle: x
2nd angle: 3x
3rd angle: x+30
Sum of all angles must be 180 degrees
x + 3x + x + 30 = 180
5x + 30 = 180
5x = 150
x = 30
The shaded region of the design shown is to be painted red. What is the area, in square units, of the shaded region? (Use = 3.14)
A 43.0
B 62.8
C 121.5
D 137.2
Answers
Answer:
A.43.0
Step-by-step explanation:
area of rectangle= l*w=10 units *20 units= 200 units^2
area of the 2 circles:
diameter= 20/2=10 units
r=d/2= 10/2=5 units
area of a circle= 3.14*r^2
=3.14*5*5
=78.5> the 2 circles are identical then they have the same area
area of the shaded region= area of the rectangle- 2*area of one circle
= 200- (2*78.5)
=200-157
=43.0
therefore the area of the shaded region is 43.0 units^2

Which fraction is equivalent to 0.8?
One-eighth

Answers
Answer:
Four-fifths (4/5)
hope it helps!
Answer:
Four-fifths
Step-by-step explanation:
To convert this decimal into a fraction remove the decimal and divide by 10, so the new fraction looks like 8/10. You do this because the eight is in the tenths place, so it literally translates to eight-tenths. However, fractions need to be in the simplest form so you divide both the numerator and denominator by 2 to get the final answer 4/5 or four-fifths.

D
В
Yes
No
Answers
Answer: No
Currently we don't have enough information to prove this quadrilateral is a parallelogram. One piece of information that would be useful would be if the other diagonal is bisected. If that's the case, then we have a parallelogram (we would first prove the triangles congruent and then use the corresponding congruent angles to set up the parallel lines). Unfortunately, we only know about one diagonal being bisected, but not both, so we don't have enough info.

Step 1: Define Equation
4x + 5 = 13x + 4 - x - 9
Step 2: Solve for x
Combine like terms: 4x + 5 = 12x - 5Subtract 4x on both sides: 5 = 8x - 5Isolate x term: 10 = 8xIsolate x: 5/4 = xRewrite: x = 5/4Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 4(5/4) + 5 = 13(5/4) + 4 - 5/4 - 9Multiply: 5 + 5 = 65/4 + 4 - 5/4 - 9Add: 10 = 81/4 - 5/4 - 9Subtract: 10 = 19 - 9Subtract: 10 = 10Here we see that 10 does indeed equal 10.
∴ x = 5/4 is the solution to the equation.
Which of these is parallel to y= 4x-2
y=5+4x
y=4-3x
y=4x+1
y=5-4x
y=4x-4
Answers
Answer:
y=4x+5(the first one)
y=4x+1
y=4x-4
Step-by-step explanation:
If the slope is the same, it is parallel
The equation for a linear equation is y=mx+b
mx is the slope
your original equation is y=4x-2, so the slope is 4.
To find which ones are parallel, you find the ones with the slope 4x(make sure it isn't -4x).

find x and y multiple choice
Answers
Answer:
x=30
y=4
Step-by-step explanation:
Since there is an equilateral triangle, those angles =60°, and all sides to that triangle are equal.
You can determine y by looking at the congruent lines on the second triangle. In this triangle, we see that two sides, one of which is a side to the equilateral triangle, are equal to 20. Because one of these sides is a side to the equilateral, we know that all sides of the equilateral triangle are equal to 20, so using simple algebra you can determine that y=4.
To solve for x is a little more difficult. In the equilateral triangle, we know that all angles =60°, therefore we can solve for two angles to use to solve for x. We can solve for the obtuse angle by subtracting 60 from 180=120. then we can solve for the next angle that is next to the equilateral triangle because these two make a right angle so 90-60=30. Now you add the angles you just solved for, subtract that sum from 180, and you get x.
120+30=150
180-150=30
x=30

A bricklayer can build a wall of a certain size in 5 hours. Another bricklayer can do the same job in 4 hours. If the bricklayers work together, how long would it take to do the job?
a. 9h
b. 2(2/9)h
c. 20h
d. 4(1/2)h
Answers
Answer:
b
Step-by-step explanation:
It will take [tex]\frac{20}{9}[/tex] hours as per linear equation to complete the wall.
What is a linear equation?A linear equation is an equation where the variable of the equation has the highest power of degree one.
Given, the 1st bricklayer build a complete wall of certain size in 5 hours.
Therefore, that bricklayer build [tex]\frac{1}{5}[/tex]th of the complete wall in 1 hour.
Similarly, the 2nd bricklayer build a complete wall of certain size in 4 hours.
Therefore, that bricklayer build [tex]\frac{1}{4}[/tex]th of the complete wall in 1 hour.
If they work together, in 1 hour they build a total of ([tex]\frac{1}{5}[/tex]+[tex]\frac{1}{4}[/tex])th = [tex]\frac{9}{20}[/tex] of the complete wall.
Hence, they will complete the wall in (1÷[tex]\frac{9}{20}[/tex]) hours = [tex]\frac{20}{9}[/tex] hours.
