Answer:
[tex]y=\frac{1}{13} x+\frac{32}{13}.[/tex]
Step-by-step explanation:
1. the midpoint of the side AC is:
[tex]D:(\frac{3-2}{2};\frac{4+1}{2})=(0.5;2.5).[/tex]
2. if the coordinates of the points B and D are (7;3) and (0.5;2.5) respectively, then it is possible to make up the required equation of the median BD:
[tex]\frac{x-7}{7-0.5}=\frac{y-3}{3-2.5}; \ \frac{x-7}{13}=\frac{y-3}{1}[/tex]
or
[tex]y=\frac{1}{13} x+\frac{32}{13}[/tex]

could you help me with this? I am very bad at math i need help
Answer:
10) 7 meters
11) 10 yards
12) 452.16 inches²
13) 235.5 meters²
14) 22608 centimeters²
15) 4220.16 centimeters²
16) 1177.5 centimeters²
17) 141.3 millimeters²
Step-by-step explanation:
10) The volume of a rectangular prism is calculated by multiplying the height, width, and length of the shape. In this question, we have the volume, the width, and height, but not the length. To find it, we can divide the width and height from the volume.
First, divide the width.
[tex]\frac{210}{5}[/tex] = 42
Next, the height.
[tex]\frac{42}{6}[/tex] = 7
The length of the shape is 7 meters.
----------------------------------------------------------------------------------------------------------------
11) For this question, we can do the same thing. Take the volume, then divide the length and width from it.
[tex]\frac{360}{6}[/tex] = 60
[tex]\frac{60}{6}[/tex] = 10
The height is 10 yards.
----------------------------------------------------------------------------------------------------------------
12) We have to find the volume of a cylinder. The formula for this is [tex]V=\pi r^2h[/tex]. We will use 3.14 for pi. The radius is 4 in and the height is 9 in. We can plug our values into the equation and solve.
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](4²)(9)
V = 3.14(4²)(9)
V = 50.24(9)
V = 452.16
The volume is 452.16 inches².
----------------------------------------------------------------------------------------------------------------
13) We will use the same formula for this. Our radius is 5 m and the height is 3 m. Plug the values in and solve.
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](5²)(3)
V = 3.14(5²)(3)
V = 78.5(3)
V = 235.5
The volume of this cylinder is 235.5 meters².
----------------------------------------------------------------------------------------------------------------
14) The radius of this cylinder is 15 cm. The height is 32 cm. Put these numbers into our formula.
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](15²)(32)
V = 3.14(15²)(32)
V = 708.5(32)
V = 22608
The volume of this cylinder is 22608 centimeters².
----------------------------------------------------------------------------------------------------------------
15) The next cylinder has a radius of 8 cm and a height of 21 cm.
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](8²)(21)
V = 3.14(8²)(21)
V = 200.96(21)
V = 4220.16
The cylinder has a volume of 4220.16 centimeters².
----------------------------------------------------------------------------------------------------------------
16) This cylinder has a radius of 5 cm and a height of 15 cm.
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](5²)(15)
V = 3.14(5²)(15)
V = 78.5(15)
V = 1177.5
The volume is 1177.5 centimeters².
----------------------------------------------------------------------------------------------------------------
17) The dimensions of this cylinder are 3 mm and 15 mm.
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](3²)(15)
V = 3.14(3²)(15)
V = 9.42(15)
V = 141.3
The volume is 141.3 millimeters².
----------------------------------------------------------------------------------------------------------------

what is the value of a when we rewrite 8^x as a^-x/9
Answer:
[tex]a = \frac{1}{134217728}[/tex]
Step-by-step explanation:
Given
[tex]8^x = a^{-x/9}[/tex]
Required
Find a
Take log of both sides
[tex]log(8^x) = log(a^{-x/9})[/tex]
Apply law of logarithm
[tex]x\ log(8) = (-x/9) log(a)[/tex]
Divide both sides by a
[tex]log(8) = -\frac{1}{9} log(a)[/tex]
Multiply both sides by -9
[tex]-9\ log(8) = log(a)[/tex]
Apply law of logarithm
[tex]log(8^{-9}) = log(a)[/tex]
Cancel out log
[tex]8^{-9} = a[/tex]
Rewrite as:
[tex]a = 8^{-9}[/tex]
Apply law of indices
[tex]a = \frac{1}{8^9}[/tex]
[tex]a = \frac{1}{134217728}[/tex]

Find the length of each trapezoid.
Answer:
EF = 27
Step-by-step explanation:
(x + 34)/2 = 2x - 13
x+ 34 = 4x - 26
3x = 60
x = 20
EF = 2(20) -13 = 27
Answer:
11. EF = 27
Step-by-step explanation:
11.
Median of a trapezoid:
2x - 13 = 20 + x + 14
2
2(2x - 13) = 20 + x + 14
4x - 26 = 34 + x
4x - x = 34 + 26
3x = 60
x = 20
EF = 2x - 13
EF = 2(20) - 13
EF = 40 - 13
EF = 27
What is the value of x? Please explain how you got to this answer so I can answer similar questions.

Helppppp plsssssssssssssssssssssss thanks シ
Step-by-step explanation:
False. the number is the x coordinate
True. the x-axis is horizontal
False. 0,0 is called the origin.
The zeroes of the function are
-2 and 0
0 and 4
-2, 0, and 4
1. x=-2, x=0
So, the equation in factored form would be x(x+2)=0.
2. x=0, x=4
So, the equation in factored form would be x(x-4)=0.
3. x=-2, x=0, x=4
So, the equation in factored form would be x(x+2)(x-4)=0.

someone please help me answer this correctly
Answer:
13 units is the answer.
Step-by-step explanation:
points (8,-4) and (3,8)
We can rewrite the Pythagorean theorem as,
[tex]d=\sqrt{(x_2 - x_1)^2+(y_2-y_1)^2} \\\\d= \sqrt{(3-8)^2 + (8-(-4))^2} \\\\d=\sqrt{(-5)^2 + (12)^2} \\\\d=\sqrt{25 + 144} \\\\d=\sqrt{169} \\\\d=13\\\\[/tex]
∴ distance between 2 points (8,-4) and (3,8) = 13 units.
equation on
1) 3x + 4 = 2x + 6
2) 4x - 9 = 2x + 1
3) 4x - 3 = x + 6
4) 5m - 2 = 16 - 4m
1.) 7x = 8x
2.) -5x = 3x
3.) 1x = 6x
4.) 3m = 12m
. Kemone bought 3 pounds of hamburger for $2.56 per pound and a box of cereal for $3.95. How can you calculate how much she spent? *
Answer:
Step-by-step explanation:
you multiply 2.56 by 3 and add 3.95 an equation would look like y=(3×2.56)+3.95
Choose 3 values for x that would make this inequality true. X - 4<20

100
Answer:
x<24
x<22
x<23
Step-by-step explanation:
X - 4<20
move 4 and add it to 20
x<24

7. The following numerical ordered sequence of numbers has a mean of 13 and a median of 14. 4. a. 8. 10. 13.b. 16. 18. 20:21 Gven this information, the values of a ondo must be:
Answer:
a = 9
b = 19
Step-by-step explanation:
DO B FIRST
The mean is the average of all the terms (numbers) in the sequence
To find the average you find the sum of the terms and divided the sum by the number of terms there are.
The mean times the number of terms equals the sum of all the terms subtract the terms that you know from the sum to get A
a = 17(10)-7-12-15-17-19-20-22-24-25
a = 170-161
a = 9
The median is found by taking the average of the two middle terms
Our middle terms are 17 and B
the median times 2 equals the sum of the two terms and then subtract the term you know from the sum
b = 18(2)-17
b = 36-17
b = 19

A football stadium holds 5000 people.
On a match day z of the stadium is full.
40% of the children are girls.
The ratio of adults to children is 2:3
How many of the children attending are boys?
Can someone plz help me with this
Answer:
1000 children
Step-by-step explanation:
Find the total units of adults and children = 2 + 3 = 5
5 units = 5000
1 unit = 5000 ÷ 5 = 1000
100% ÷ 5 units = 20% each unit
3 units = 20% x 3 = 60%
Since we all know that 60% of the people are children and 40% of the children are girls...
60 - 40 = 20%
20% = 1000
