Given:
The endpoints of line segment CD are C(-2,0) and D(4,9).
To find:
The midpoint of CD.
Solution:
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Using the midpoint formula, the midpoint of CD is
[tex]Midpoint=\left(\dfrac{-2+4}{2},\dfrac{0+9}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{2}{2},\dfrac{9}{2}\right)[/tex]
[tex]Midpoint=\left(1,4.5\right)[/tex]
Therefore, the midpoint of the line segment CD is (1,4.5).

Step-by-step explanation:
Daniel wants to order shirts on the internet. Shirts cost $20.00 and shipping on all orders is $10.99. Daniel has $50 to spend.
Answer:
Total cost: $30.99
Daniel will have $19.01 left to spend.
Answer:
Daniel can buy 1 shirt
Step-by-step explanation:
We can write an equation out of what they give us in the question.
Each shirt is $20, this can be represented as 20s.
All shipping on orders cost $10.99, this can be represented as 10.99s.
S represents how many shirts Daniel will buy.
The equation is written out like this:
[tex]20s + 10.99s \leq 50[/tex]
Combine like terms:
[tex]30.99s \leq 50\\[/tex]
Now solve
[tex]s \leq 1.6[/tex]
Therefore, if Daniel can only buy one shirt if he has only $50 to spend.
We can't have 2 shirts because that would exceed the $50 limit.
Hope this helps!!

The graph shows the number of cups of coffee Sherwin consumed in one day and the number of hours he slept that same night:
A scatter plot is shown. Data points are located at 1 and 9, 3 and 5, 5 and 6, 4 and 4, 2 and 7, and 6 and 4. A line of best fit crosses the y-axis at 10 and passes through the point 6 and 4.
How many hours will Sherwin most likely sleep if he consumes 9 cups of coffee?

What is the Slope of the segment With endpoints at (300, -2) (500, 6)?
Answer:
[tex]\frac{1}{25}[/tex]
Step-by-step explanation:
to find slope: [tex]m = \frac{y_2 - y_2}{x_2 - x_1}[/tex]
[tex]m = \frac{6 - (-2)}{500-300} = \frac{8}{200\\}\\m = \frac{1}{25}[/tex]
A ladder 17 m long reaches a window 8 m high on one side of the road. the ladder is then turned over to the opposite side of the road and is found to reach another window 15 m high. Find the width of the road.Please apply the pythgoras property .
Answer:
23 mStep-by-step explanation:
It is assumed the width of the street is the distance between the opposite buildings.
See the picture attached
It comprises of two parts:
x and yUsing Pythagorean theorem, lets find the value of x:
x² + 15² = 17²x² = 289 - 225x² = 64x = 8 mSame rule for y:
y² + 8² = 17²y² = 289 - 64y² = 225y = 15 mThe width of the street (road) is:

Question
1 A rectangular block of steel measures 4 cm x 2 cm x 1.5 cm. Its trass is 93.6g.
Calculate the density of steel.
b Steel is made almost entirely of iron atoms, but it is denser than iron.
Suggest a reason for this.
a
Answer:
[tex]d=7.8\ g/cm^3[/tex]
Step-by-step explanation:
Given that,
The dimensions of a rectangular block = 4 cm x 2 cm x 1.5 cm
Mass, m = 93.6 g
We need to find the density of steel. We know that the density of an object is equal to the mass divided by volume. So,
[tex]d=\dfrac{m}{V}\\\\d=\dfrac{93.6}{4\times 2\times 1.5}\\\\d=7.8\ g/cm^3[/tex]
So, the density of the steel is [tex]7.8\ g/cm^3[/tex].

Really confused, can someone help me?
First Answer:
x = 12
First Step-by-step explanation:
12 + x = -3(4 - x)
12 + x = -12 + 3x
- x - x

12 = -12 + 2x
+ 12 + 12
—————————
24 = 2x
24/2 = 2x/2
12 = x
Second Answer:
No solution
Second Step-by-step explanation:
2(x - 1/2) = 8 + 2x
2x - 1 = 8 + 2x

Write your answer as an integer or as a decimal rounded to the nearest tenth.
AB =
Answer:
AB ≈ 7.0
Step-by-step explanation:
Using the sine ratio in the right triangle
sin61° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{8}[/tex] ( multiply both sides by 8 )
8 × sin61° = AB , then
AB ≈ 7.0 ( to the nearest tenth )

There are 18 black socks and 12 navy socks in your drawer. The room is dark and you can't turn on the light. What is the least number of socks that you have to take you of the drawer to be certain that you have a pair of the same color? The solution is a number.
9514 1404 393
Answer:
3
Step-by-step explanation:
The largest number you can take without having a pair is the number of colors, 2. One more sock must match one already in hand.
You must take one more than the number of colors:
2 + 1 = 3
You must take 3 socks to be certain of a pair the same color.

2. Samuel used clay to make a diorama of the pyramids in Ancient Egypt. He made two triangular pyramids and three rectangular pyramids. How much clay did he use to create all the pyramids?
Answer:
[tex]124.16[/tex] cubic meter of clay will be used to create all the pyramids
Step-by-step explanation:
The remaining part of the question is given in the attached file
Solution
The total clay used is equal to the sum of volumes of two triangular and three rectangular pyramids.
For Rectangular Pyramid,
Volume of three rectangular pyramids
[tex]3 * \frac{BH}{3} = BH[/tex]
Substituting the given values in above equation, we get -
[tex]15.5 * 5 = 77.5[/tex] cubic centimeter
For triangular Pyramid,
Volume of two triangular pyramids
[tex]2 * \frac{BH}{3}\\2 * \frac{10 * 7}{3}[/tex]
[tex]46.67[/tex] cubic centimeter
Total clay used = Volume of 3 rectangular pyramid + volume of 2 triangular pyramid [tex]= 77.7 + 46.67 = 124.16[/tex] Cubic centimeter
Mr. Hayes has 11 straw bundles to use forr bedding in his horse stalls. What is the greatest number of stalls he can fill if each stall holds exactly 4 bundles
Answer:
2 stalls
Step-by-step explanation:
Mr. Hayes has 11 straw bundles to use forr bedding in his horse stalls. What is the greatest number of stalls he can fill if each stall holds exactly 4 bundles
1 stall = 4 bundles
4 bundles = 1 stall
11 bundles = x
Cross Multiply
4x = 11
x = 11/4
x = 2 3/4 stalls
The greatest number of stalls he can build is 2 stalls
Plea look at the photo of Parallelogram properties.
Question: Find the measurement indicated in each parallelogram.
Please explain it you can:)
Answer:
1. 45
2. 105
3. 95
4. 85
Step-by-step explanation:
For problems 1 and 4:
Consecutive angles are supplementary in a parallelogram, which means they equal 180.
180 - 135 = 45
180 - 95 = 85
For problems 2 and 3:
Opposite angles are congruent or equal each other in a parallelogram,
The sun of two numbers is 36. The larger number is 18 more than the smaller number. What are the numbers?
Answer:
Step-by-step explanation:
a+b=36
lets name the 2 numbers a,b
b=a+18
a+a+18=36
2a=36-18
2a=18
a=9
b=27
Answer:
the numbers are 9 and 27
Step-by-step explanation:
equation to the problem: x+y=36
one number (y) is 18 times greater than the other number (x): x+18=y
plug in the 2nd equation to the first equation (systems of equations):
x+(x+18)=36
solve the equation:
2x+18=36
*minus 18 on both sides*
2x=18
*divide the whole equation by 2 to get the value of just one x*
x=9
since variable x is the n smaller number, add 18 to 9 to get the 2nd number:
18+9= 27
y=27

Answer:
465 in²
Step-by-step explanation:
square area: A = lw
triangle area: A = [tex]\frac{1}{2}[/tex] lw (or base x height)
[tex]A_{square}[/tex] = (15)(15) = 225
[tex]A_{triangle}[/tex] = [tex]\frac{1}{2}[/tex] (8)(15) = 60
There is one square and 4 triangles so...
225 + 4(60) = 465 in²
The data to represent average test scores for a class of 16 students includes an outlier value of 78. If the mean, including the outlier of 78, equals 84, which statement is always true about the new data when the outlier is removed?
The mean would increase.
The mean would decrease.
The median would increase.
The median would decrease.
Answer:
Given that The data to represent average test scores for a class of 16 students includes an outlier value of 78.
We can find sum of all 16 test scores = 84(16) = 1344
Outlier found = 78
If outlier is removed new sum = 1344-78 = 1266
Number of entries without outlier = 15
New average = 1266/12 =84.4
We find that average of new data increases.
Also whenever we remove outlier std deviation also would be reduced.
Step-by-step explanation:
Answer:
The mean would decrease.
Step-by-step explanation:
Without the outlier, the mean decreases. The median stays the same with or without the outlier.
