Step-by-step explanation:
The midpoint of any line segment is the average of the coordinates of the endpoints.
mp=((x2+x1)/2, (y2+y1)/2), in this case we have points (9,7) and (5,3) so

Box A contains 10 pens that are either red or blue in colour. Box B contains 23 pens that are also either red or blue in colour. The number of blue pens in Box B is twice the number of blue pens in Box A while the number of red pens in Box B is thrice the number of red pens in Box A. Write a pair of linear equations using b as the number of blue pens in Box A and r as the number of red pens in Box A.
Answer:
b + r = 10 - - (1)
2r + 3b = 23 - - (2)
Step-by-step explanation:
Number of Blue pens in box A = b
Number of red pens in box A = r
BOX A :
Contains 10 pens that are either red or blue
b + r = 10
BOX B:
Contains 23 pens that are either red or blue ;
Red pens in box B = 2 tines the number of red pens in box A
Blue pens in box B = 3 times the number of blue pens in box A
2r + 3b = 23

Answer:
Part A is no because after subtracting it is 6/10 and 6/10 is not equal to 1/2
Step-by-step explanation:
First you make the fraction's denominator equal
2/5 = 4/10
Camen's water bottle is 1 8/10
Jorge's water bottle is 2 4/10
1/2 = 5/10
Make the fractions into a improper fraction
Camen's is 18/10
Jorge's is 24/10
subtract it
24 - 18 = 6
So Part A is no because after subtracting it is 6/10 and 6/10 is not equal to 1/2

Find the sum of first term of the sequence 1,2,4,8,12
Answer:
The right solution is "18". A further explanation is given below.
Step-by-step explanation:
The given series is:
1,2,4,8,12
Here,
First term,
a₁ = 1
Second term,
a₂ = 2
Last term,
n = 12
Now,
The sum of the sequence will be:
⇒ [tex]S_n = \frac{n ( a 1 + a 2 ) }{2}[/tex]
On substituting the values, we get
⇒ [tex]=\frac{12(1+2)}{2}[/tex]
⇒ [tex]=\frac{12\times 3}{2}[/tex]
⇒ [tex]=\frac{36}{2}[/tex]
⇒ [tex]=18[/tex]

The correct expression will be ( x- 4 ). So option B is right.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The expression will be solved as:-
E = ( - √(x-4))²
The product of two minuses is positive and the product of the same square root numbers will be the number so the equation will become.
E = -√(x-4) x -√(x-4)
E = x - 4
Therefore the correct expression will be ( x- 4 ). So option B is right.

The area if a rectangular frame is 32 square inches. The perimeter of the frame is 24 inches. Which shows the correct dimensions of the frame?
Answer:
8 x 4
Step-by-step explanation:
Lets say the length is x and the width is y.
xy = 32
2x + 2y = 24
Rearranging the second equation, we get:
2x = 24 - 2y
/2 /2
x = 12 - y
substitute into the first equation
y(12 - y) = 32
12y - y^2 = 32
-32 -32
-y^2 +12y - 32 = 0
x -1 x -1
y^2 - 12y + 32 = 0
(y - 8)(y - 4) = 0
y = 8 or 4
substitute into x = 12 - y.
x = 12 - 8 = 4
x = 12 -4 = 8
so the correct dimensions are 4 x 8, as either x = 4 and y =8, or x = 8 and y = 4.

Evelyn answered 42 questions correctly on her multiple choice history final and earned a grade of 21%. How many total questions were on the final exam?
Answer:
200 questions
Step-by-step explanation:
Given data
Let the total questions be x
so that
21% of x= 42 questions
let us solve for x
21/100*x= 42
0.21*x= 42
0.21x= 42
Divide both sides by 0.21
x= 42/0.21
x= 200 questions
Hence the questions are 200 questions

Step-by-step explanation:
this is confusing b/c they are asking about two trains traveling at differnt speeds, but.. if you put the speeds together and make one train... imaginary.. ofc... traveling at the speed of both trains combined... when will it be 50 miles from the station?
maybe you can solve that? I'll solve it below.. but.. if you can.. try it now, on your own
below is my answer... don't look until you have solved yours :P
80+70= 150kph
when will this have traveled 50Km?
you may be able to see that it will take 1/3 of an hour to travel 50 km
so 60 minutes times 1/3 = 20 minutes :)
Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio. A (-5, 12) B (11, 0) 1 :3
Answer:
(7, 3)
Step-by-step explanation:
Using the midpoint formula
M(X, Y) = {(ax1+bx2/a+b), ay1+by2/a+b}
X = ax1+bx2/a+b
X = -5(1)+3(11)/1+3
X = -5+33/4
X = 28/4
X = 7
Y = ay1+by2/a+b
Y = 1(12)+3(0)/1+3
Y = 12/4
Y = 3
Hence the coordinate of P is at (7, 3)

You are making a scale model of your house. Your bedroom is 10'x8'. In your scale model, it will be the longer side of the bedroom will be 3 inches. How big will the shorter side be?
Answer:
2.4 inches
Step-by-step explanation:
Actual Dimension of bedroom = 10' * 8'
In the model ; longer side = 3 inches
Length of shorter side in the model ;
Longer side of actual bedroom = 10'
Scale factor * length = model length
Scale factor * 10 = 3
Scale factor = 3/10
Hence, length of shorter side :
Scale factor * actual length of shorter side
3/10 * 8
24 / 10
= 2.4 inches

calculate the size of angle AEF
Answer:
Accuate Angel 230 digre
Answer:
90 degrees
Step-by-step explanation:
The sum of the measures of interior angles in a quadrilateral is 360 degrees. A quadrilateral is any shape that has 4 sides. ABCD is a square, and squares have 4 sides, so the sum of the angles inside of the square will be equal to 360. A square has 4 angles, each with equal measure, so to find the measure of one angle, divide 360 by 4: 360/4=90. Each angle in a square measures 90 degrees.Triangle DEF is an equilateral. This means that each side is equal, but it also means that each angle will be equal too. The sum of the measure of interior angles in a triangle is 180 degrees, and a triangle has 3 angles, therefore you can find the measure of each angle in an equilateral by dividing 180 by 3: 180/3=60. Each angle in an equilateral triangle measures 60 degrees.The measure of a straight line is always 180 degrees. CDF is a straight line, and it is made up of 3 angles:-Angle CDA
-Angle ADE
-Angle EDF
Since the measure of CDF has to be 180 degrees, the measures of angles CDA, ADE, and EDF must add up to 180.Angle CDA is an angle of a square, so it is equal to 90 degreesAngle EDF is an angle of an equilateral triangle, so it is equal to 60 degrees.The angles must add up to 180, so 90+60+ADE=180You can subtract 90 and 60 from 180 to find the measure of ADE: 180-90-60=30The question tells us that triangle ADE is isosceles. There is a theorem called base angles theorem, and it states that if two sides of a triangle are equal in length, then the two angles opposite from them will be equal in measure. Using this theorem, we can find that the measure of angle ADE is equal to the measure of AED. We already found out that ADE is 30 degrees, so AED is also 30 degrees. But the angle we are looking for is AEF:AEF is made up of angles AED and DEF, so the measures of angles AED+DEF=AEF. DEF is part of the equilateral triangle, so we know it is 60 degrees. We already found that AED is 30 degrees, so add 30 and 60 degrees: 30+60=90. AEF is 90 degrees.Which of the following is true regarding the solutions to the logarithmic equation below?
