In the figure below, C is between A and D, and B is the midpoint of AC. If BC= 3 and BD=10, find AD.
The line segment AD measures 13 units.
What is a line segment?
A line segment in geometry has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a line that links two places. The difference between a line and a line segment is that a line has no endpoints and can go on forever in either direction.
A line segment AD is given.
Four points A, B, C and D are placed.
It is given that measurement of BC = 3 units.
Also, measurement of BD = 10 units.
Since, B is the midpoint of AC, so -
AB = BC
So, the measurement of AB = 3 units
The measurement of CD can be found as -
CD = BD - BC
CD = 10 - 3
CD = 7 units
So the measurement for line segment AD is -
AD = AB + BC + CD
AD = 3 + 3 + 7
AD = 13 units
Therefore, the measurement value is 13 units.

Shade one more square to make a
pattern with rotational symmetry order 2.
Answer:
shade the square that is 1 above the bottom right
To make a pattern with rotational symmetry order 2 we need to shade the square that is 1 above the bottom right.
What is rotational symmetry?The rotational symmetry of a shape explains that when an object is rotated on its own axis, the shape of the object looks the same. Many geometrical shapes appear to be symmetrical when they are rotated 180 degrees or with some angles, clockwise or anticlockwise.
Given is a figure of square box, of 5x5, we need to complete the shaded part so, that the resulting figure will be rotational symmetric,
Since, the figure needs to be rotational symmetric, that means, the figure will be same no matter how many times we rotated it,
If we shade the one square which is the last box of the fourth line, then it will be a figure which is rotational symmetric.
Hence, to make a pattern with rotational symmetry order 2 we need to shade the square that is 1 above the bottom right.

What is the GCF of 52/65?
Answer:
The greatest Common factor of 52/65 is 13!
Step-by-step explanation:
Hope this helps :)
Pls make brainliest :p
And have an amazing day <3
Answer:
13
Step-by-step explanation:
The GCF of numbers can be found by first finding the prime factors of the numbers.
52 = 2^2 * 13
65 = 5 * 13
The GCF is the product of common factors with lower exponent.
The only common factor is 13.
GCF = 13
To reduce the fraction, divide the numerator and the denominator by the GCF.
(52/13) / (65/13) = 4/5

I couldn't do 19.) and 20.) for you because there are weird symbols that I believe you mistakenly input. But I'm sure you now get the gist of how to solve such problems. Peace <3
Step-by-step explanation:
All you really have to do for all of the problems is substitute your value of "x" for the function.
17.) f(x) = 8x - 7; f(x) =17
17 = 8x -7 ---- substitute 17 for f(x), add 7 on both sides
24 = 8x ------ divide 8 on both sides
x = 3
18.) g(x) = -4x + 7; g(x) = 27
27 = -4x + 7 substitute 27 for g(x), subtract 7 on both sides
20 = -4x
x = -5

Joel runs the same distance
every day. Last week he ran
28 miles in 4 days. Find the
constant of proportionality
that relates the number of
miles, y, to the number
of days, x?
The constant of proportionality that relates the number of miles y, to the number of days x is [tex]\frac{1}{7}[/tex] .
What is proportionality?
In general, the word "proportion" is used to describe a part, share, or amount that is compared to an entire. Two ratios or fractions being equal is expressed by an equation or a statement. An analysis of two numbers in terms of their proportion. A ratio is said to be directly proportional to another if two sets of supplied numbers are increasing or decreasing in the same ratio. With the "::" or "=" symbol, proportions are indicated.
Here if the days are increasing then distance also increased . Then days directly proportional to the distance .
=> Number of days ∝ Total distance
=> x∝y
To remove proportion we hate to add constant K.
=> x= ky
Here if he runs 28 miles in 4 days. x=4, y=28.
=> 4 = k*28
=> k = 4/28
=> k = [tex]\frac{1}{7}[/tex]
the equation is x = [tex]\frac{1}{7}[/tex]y
Hence the constant of proportionality that relates the number of miles y, to the number of days x is [tex]\frac{1}{7}[/tex] .

how much does carl earn per hour?show your work .
Answer:
Step-by-step explanation:
From the table showing in the diagram, Let's pick the data in the first row:
Time = 3 hours
Money earned = $45
The amount of money Carl earns per hour is calculated as:
3 hours = $45
1 hour = ?
Cross Multiply
1 hour x $45 / 3 hours
= $15
Let's confirm our answer using the data in the last column
Time = 10 hours
Money earned = $150
The amount of money Carl earns per hour is calculated as:
10 hours = $150
1 hour = ?
Cross Multiply
1 hour x $150 / 10 hours
= $15
Therefore, the amount of money Carl earns per hour is $15
Answer:
he earns 15 dollars per hour. 45/3 is 15

in each bouquet of flowers, there are 6 roses and 10 white carnations. complete the table to find how many roses and carnations there are in 2 bouquets of flowers.
Answer:
in two bouquets of flowers there would be, 12 roses and 20 white carnations.
Step-by-step explanation:
In each bouquet there are 6 roses and 10 white carnations, if there's 2 bouquets of flowers that means that there 2 x 6 and 2 x 10.
2 x 6 (or 6 + 6) = 12
2 x 10 (or 10 + 10) = 20
so in two bouquets there are 12 roses and 20 white carnations.
because in a single bouquet there are 6 roses and 10 white carnations so just double it!

Find the measure of each angle.
ZUVW and ZXYZ are complementary angles, mZUVW= (x - 10), and mZXYZ= ( 4X – 10),
Answer:
<ZUVW = 12 degrees
<ZXYZ = 78 degrees
Step-by-step explanation:
x - 10 + 4x - 10 = 90
5x -20 = 90
5x = 90 + 20
x = 110/5
x = 22
mZUVW = 22 - 10 = 12 degrees
mZXYZ = 4(22) - 10
= 78

Answer:
[tex]Their \: sum \: is -334[/tex]
[tex]x + x+1 + x+2 + x+3 = -334[/tex]
[tex]4x + 6 = -334[/tex]
[tex]4x = -340[/tex]
[tex]x = -85 [/tex]
Step-by-step explanation:
[tex]Thanks!!!!![/tex]
Answer:
the first number is x (x ∈ Z)
=> four consecutive integers are x, x + 1, x +2, x + 3
because the sum of them = -334, we have:
x + (x + 1) + (x + 2) + (x + 3) = -334
⇔ 4x + 6 = -334
⇔ 4x = -334 - 6 = -340
⇔ x = -340/4
⇔ x = -85
=> 4 consecutive integers are -85; -84; -83; -82
