Answer:
12000
plss mark brainliest
Step-by-step explanation:
8000÷2/3
Explanation:
x = full tank capacity
2/3 of x = (2/3)*x = 8000 which is the amount Ron states when its 2/3 full
To solve for x, we will multiply both sides by 3 and then divide both sides by 2 like so
(2/3)x = 8000
2x = 8000*3
2x = 24000
x = 24000/2
x = 12000 liters is the full capacity
Note that,
2/3 of 12000 = (2/3)*12000 = 8000
which confirms our answer.

Find the midpoint between two points on a coordinate plane whose coordinates are (5, 7) and (-3, 1).
A. (4,4)
B. 12,8)
C. (8,8)
D. (1.4)
Answer:
(1,4)
Step-by-step explanation:
To find the x coordinate of the midpoint, average the x coordinates of the endpoints
(5+-3)/2 = 2/2 =1
To find the y coordinate of the midpoint, average the y coordinates of the endpoints
(7+1)/2 = 8/2 =4

The population of a municipality before 2 years was 60,000 and the rate of annual growth of population is 2%. If the numbers of in-migrants and out-migrants at the end of 2 years were 750 and 410 respectively and 620 people died within this time interval, find the present population of the municipality.
Answer:
62,144
Step-by-step explanation:
60,000 x (1 + 2%)^2 : growth in 2 years
+ 750: in migrants
- 410: out migrants
- 620: died
Answer:
62,144
Step-by-step explanation:
[tex]60,000 \times (1 + 2\%)^{2} [/tex]
➡️ [tex] = 62,424[/tex]
In-migrants:
➡️ [tex]750 - 410 = 340[/tex]
now:
[tex]62,424 + 340 - 620[/tex]
➡️ [tex] = 62,144[/tex]
So, the present of the municipality is 62,144
Two rectangles are similar. The smaller has a length of 8 cm and an area of 40 cm.
If the width of the larger rectangle is 10 cm, find its area.
Answer:
160 cm²
Step-by-step explanation:
If the two rectangles are similar, that means they have equal scale factors. The smaller rectangle has length of 8 cm and area of 40 cm, which means the width is 5 cm.
The width of the larger rectangle is 10 cm, which is double the width of the smaller, similar rectangle. So, to find the length of the larger rectangle, multiply 8 x 2, which gives you 16 cm for the length, since the scale factor is 2.
Now, just find the area of the larger rectangle by doing length x width. 16cm x 10 cm = 160 cm²
Answer:
160 cm^2
Step-by-step explanation:
Our strategy is to find the length of the larger rectangle so we can find the area. To find the length, we will rely on the fact the two rectangles are "similar": their sides are in equal proportions, or have the same "ratio."
We know that the smaller rectangle has a width of 5 cm because, when we substitute area and length into
A = lw
we get
40 = 8w
w = 5
when we divide both sides by 8.
Because of equal proportions:
Width : length of the smaller rectangle = Width : length of the larger rectangle
We can write an equation
5 / 8 = 10 / x
Cross multiply
5x = 80
x = 16
So the larger rectangle has a length of 16 cm and a width of 10 cm (given)
meaning the area is
16 * 10 = 160 cm^2
-2/9n + 14 = 6
What is this question simplified?
-2/9 n= - 8
2n = 72
N=36
Jdbzjdjdndkdkjdd
Answer:
[tex]n = \frac{1}{36} [/tex]
Step-by-step explanation:
[tex] \frac{ - 2}{9n} + 14 = 6[/tex]
[tex] - \frac{ 2}{9n} + 14 = 6[/tex]
[tex] - \frac{2}{9n} = 6 - 14[/tex]
[tex] - \frac{2}{9n} = - 8[/tex]
[tex]2 = 72n[/tex]
[tex]n = \frac{1}{36} [/tex]

A and B are vertical angles. If m A = (4x + 8)° and m B = (2x + 28)°,
then find the value of x.
Answer:
x = 10
Step-by-step explanation:
By the Vertical Angles Theorem that states the vertical angles are congruent.
4x+8 = 2x + 28
-8 -8
-----------------------
4x = 2x + 20
-2x -2x
-------------------------
2x = 20
/2 /2
--------------------------
x = 10
Answer:
[tex](4x + 8) = (2x + 28) \\ \\ 4x + 8 = 2x + 28 \\ \\ 4x - 2x = 28 - 8 \\ \\ 2x = 20 \\ \\ x = \frac{20}{2} \\ \\ x = 10[/tex]
Vertical angel are always Equal ( = )
25 POINTS, I DONT UNDERSTANDDDDDD :C WHAT IS SO MISLEADING ABOUT THIS GRAPH???
Answer:
honestly, the graph look totally fine...
If one ere pressed to find something to complain about it, one could suggest that you do not know if this was the starting price of the stock or the ending price of the stock each day?... One could also argue that to be a bit more meaningful you might want to know the range of prices during each day...
look up what is called a candle stick graph.. each day looks like a candlestick... the top is the highest value each the bottom the lowest, and there is a line in the candle that shows the closing price

7. A kite in the shape of a square with a diagonal 32 cm and an isosceles triangle of base 8 cm and sides 6 cm each is to be made of three different shades as shown in Fig. 8.17. How much paper of each shade has been used in it?
Answer:
Step-by-step explanation:
diagonal = 32 cm
Area of square = [tex]\dfrac{d^{2}}{2}[/tex]
[tex]=\dfrac{32*32}{2}\\\\=512 \ cm^{2}[/tex]
Diagonal separate the square into two equal triangles.
Area of upper triangle that is shaded black = area of lower triangle = 512/2
= 256 cm²
Isosceles triangle:
a = 6 cm ; b = 6 cm c = 8cm
[tex]s = \dfrac{a+b+c}{2}\\\\=\dfrac{6+6+8}{2}\\\\=\dfrac{20}{2}\\\\=10\\\\s-a = 10 - 6 = 4 \ cm\\\\s-b = 10-6 = 4 \ cm\\\\c - c = 10 - 8 = 2 \ cm\\\\Area = \sqrt{s*(s-a)(s-b)(s-c)}\\\\=\sqrt{10*4*4*2}\\\\=\sqrt{2 * 2 * 4 * 4 * 5}\\\\=4*2\sqrt{5}\\\\=8\sqrt{5}\\\\=8*2.24\\\\=17.92 \ cm^{2}[/tex]
Area of black shade paper = 256 + 17.92 = 273.92 cm²
Area of white shade paper = 256 cm²
Area of the isosceles triangle = s(s-a)(s-b)(s-c)

Given that x = 2 and y = 3, how much
less is the value of 3x2 – 2y than the
value of 3y2 – 2x?
Answer:
17
Step-by-step explanation:
Evaluate the 2 expressions by substituting x = 2 , y = 3 into them
3x² - 2y
= 3(2)² - 2(3)
= 3(4) - 6
= 12 - 6
= 6
---------------------------
3y² - 2x
= 3(3)² - 2(2)
= 3(9) - 4
= 27 - 4
= 23
Then 23 - 6 = 17
Can someone help, I swear this is easy but I’m pretty sure I’m overthinking this and I’m going to have a breakdown!!!LOLZ
Hey there! I'm happy to help!
A translation is just when they are staying the same. You just move the figure along but it doesn't switch the way it is facing.
A reflection is when it is like going over a mirror. It's kind of like it rolls over. So if you are facing left on the ground and you roll over then you are facing the right. That's basically what a reflection is.
A rotation is pretty self explanatory, it's when you twist it sideways, upside down, etc. A rotation can also end up in the same position as a reflection. For example if you diagonally reflect something it is the same as a 180 degree rotation, and that might be what is stressing you out.
With your answers, I'm assuming each number has all three possible answers, so if one seems to have both, just see which answer you haven't used yet.
1) Rotation, Translation Reflection
2) Rotation, Reflection, Translation
3) Translation, Rotation, Reflection
4) Rotation, Reflection, Translation
5) Reflection, Rotation, Translation
6) Reflection, Rotation, Translation

Step-by-step explanation:
Find the largest prime factor of 18! + 19! + 20!
18! is common to each term in the sum:
18! + 19! + 20! = 18! (1 + 19 + 19×20) = 18!×400
The largest prime factor of 18! is of course 17.
Meanwhile,
400 = 16×25 = 2⁴×5²
so the largest prime factor of 18! + 19! + 20! is 17.
urgent help needed fast
Answer:
Below
Step-by-step explanation:
You can use this formula to find the sum of an arithmetic series
Sn = n / 2 (a1 + an)
You need to find the number of terms in each series before using the formula
Tn = a + (n - 1) d
a) 53 = 5 + (n - 1) 3
n = 17
Sn = 17 / 2 (5 + 53)
= 493
b) 98 = 7 + (n - 1) 7
n = 14
Sn = 14 / 2 (7 + 98)
= 735
c) -102 = 8 + (n - 1) -5
n = 23
Sn = 23 / 2 (8 + (-102))
= - 1081
d) 41/3 = 2/3 + (n - 1) 1
n = 14
Sn = 14 / 2 (2/3 + 41/3)
= 301 / 3 or 100 1/3
