A) 4
B) 5
C) 7
D) 9
9514 1404 393
Answer:
C) 7
Step-by-step explanation:
We have ...
TS +SR = 19
SR +RQ = 13
Adding these two equations together, we have ...
TS +2·SR +RQ = 19 +13 = 32
We also have ...
TS +SR +RQ = 25
Subtracting this from the equation above, we have ...
(TS +2·SR +RQ) -(TS +SR +RQ) = 32 -25
SR = 7

Step-by-step explanation:
The midsegment AC is half the sum of the parallel bases, that is
AC = [tex]\frac{DF+EB}{2}[/tex] , then
x = [tex]\frac{13+9}{2}[/tex] = [tex]\frac{22}{2}[/tex] = 11 → D

Rotate triangle P 90° clockwise about the point (2, -1).
Please screenshot this and send me the answers cuz I really need help :(
Answer: (2,0), (2,1), and (6,1)
Step-by-step explanation: I just used the desmos graphing calculator to find the answer to your problem. I don't know any formulas to solve it so I just rotated the points by hand. I also made sure they were still equidistant from the point (2,-1) because if their distances from other points changed during the rotation, then the triangle would not be equal to the first triangle and the image would've been distorted.
I hope this helps! Have a nice day.

Step-by-step explanation:
the area of a circle is 81 pi m^2. what is the circumference, in meters? express your answer in terms of pi.
============================================================
Explanation:
The area 81pi square meters leads to the radius 9 meters
Use the formula A = pi*r^2 to see why this is the case. You plug in A = 81pi and solve for r to get r = 9.
-----------------
Once you know the radius, you can determine the circumference C
C = 2*pi*r
C = 2*pi*9
C = 2*9*pi
C = 18pi
The circumference is the perimeter, or distance, around the circle.
What is the value of x? (giving brainliest and thanks to all!)
Answer:
x = 12
Step-by-step explanation:
Given a line parallel to a side of the triangle and it intersects the other 2 sides then it divides those sides proportionally, that is
[tex]\frac{x}{24}[/tex] = [tex]\frac{5}{10}[/tex] ( cross- multiply )
10x = 120 ( divide both sides by 10 )
x = 12
Math question part 2 show work thanks Jim !!
Part (b)
The scale 1 cm = 2 m means we'll multiply whatever the cm distance is by 2 to get the meter distance in real life.
The shed is 3 cm by 3 cm on paper. It corresponds to 6 meters by 6 meters in real life.
----------
The cement pad is 6 meters by 10 meters in real life because it's originally 3 cm across and 5 cm vertical. We double each dimension as done before, and replace "cm" with "m".
----------
The hot tub is a circle so we don't get an exact measurement here. But we can determine a good estimate. It appears it's 2 cm across and 2 cm vertical. So that corresponds to 4 meters by 4 meters
=========================================
Part (c)
On paper, the distance is 4.5 cm since we count out 4 full squares plus half a square when going a horizontal distance from the cement pad to the pool.
Therefore, the distance in real life is 9 meters
1 cm = 2 m
4.5*(1 cm) = 4.5*(2 m)
4.5 cm = 9 m
==========================================
Part (d)
The flowerbed on paper has sides of 4 cm and 6 cm. Use the pythagorean theorem to find the hypotenuse is approximately 7.21 cm.
Double each dimension, and replace the 'cm' with 'm'
The side lengths of the actual flowerbed is 8 meters, 12 meters, 14.42 meters. That last value being approximate.
Add up the values to get the perimeter: 8+12+14.42 = 34.42
Answer: perimeter = 34.42 meters (approximate)

For two odd consecutive numbers, seven times the first number is 1 more than six times the greater number. What is the sum of those numbers?
9514 1404 393
Answer:
28
Step-by-step explanation:
Let x represent the even number between them. Then the desired sum is 2x.
The given relation is ...
7(x -1) = 1 +6(x +1)
x = 14 . . . . . . . add 7-6x
2x = 28 = sum of those numbers

Answer:
y = 3x + 1.
Step-by-step explanation:
The slope is 3 and the y-intercept is at y = 1.
Answer:
y = 3x + b
Step-by-step explanation:
Essentially the question is asking us to find the equation of the line in slope intercept form
Slope intercept form: y = mx + b
Where m = slope and y = y intercept
First let's find the slope
Slope = change in y over change in x
Looking at the line as y goes up 3 x goes up 1
hence slope (m) = 3/1 or just 3
Now let's find the y intercept
The y intercept is equal to the y value of the point where the line passes the y axis
The line passes the y axis at ( 0 , 1 ) and the y value of that point is 1
Hence, y intercept (.b ) = 1
Finally we substitute 3 for m and 1.for b in y = mx + b to get the equation of the line
We get y = 3x + 1.
What is the result when the number 82 is decreased by 8.6%? Round your answer to the nearest tenth.
Answer:
74.948
Step-by-step explanation:
Have a nice day
Answer:
74.948
Step-by-step explanation:
To decrease a number by a percentage, we can simply multiply the number by the reciprocal of the decrease.
To decrease 82 by 8.6 % , we can simply multiply 82 by 91.4%……..
82 x .914= 74.948
Rounded to nearest tenth……..74.9

David has a wooden board that is 6 feet long. How many pieces can be cut from the board if the length of each piece is 13 of a foot?
Answer:
We are dividing a slab of wood into equal pieces, so the obvious function would be to divide. And how long are the pieces going to be? 1/4 of a foot. so that gives us:
6 ÷ ¼.
Now, when we divide by a fraction, we flip the numerator and denominator and multiply, so the equation will look like:
6 * 4
Solve that, and you'll have your answer.
Step-by-step explanation:
Hope this answer helps you :)

Can anyone help with Qs 22-25 pls !!
Or the ones you are able to do
24) IN A PARALLELOGRAM OPPOSITE ANGLES ARE EQUAL
3y + 2 = 62
3y = 62 - 2
3y = 60
y = 60/3
y = 20°
ALSO IN A PARALLELOGRAM ADJACENT SIDES SUM IS 180°
62 + 5x + 3 = 180°
5x + 65 = 180
5x = 180 - 65
5x = 115
x = 115/5
x = 23°
so option c is correct
.
.
.
25) IN A PARALLELOGRAM THE SIDES OF SAME DIAGONAL ARE EQUAL
5x - 4 = 10x - 24
5x - 10x = -24 + 4
-5x = -20
x = 20/5
x = 4
4x + 14 = 3y + 9
4(4) + 14 = 3y + 9
16 + 14 = 3y + 9
30 = 3y + 9
3y = 30 - 9
3y = 21
y = 21/3
y = 7
.
.
.
so option b is correct

6. The word ‘COMMITTEE’ has 9 letters.
So it can be permuted in 9 ways, but we’ve got letters repeating there. To avoid the same arrangements happening again, we eliminate the repetitions.
M repeats twice. T Twice. E twice.
7. If it must be greater than 2000 , the first digit must either be 2 or 3 , which means you will have 2 choices. After that, there will be 3 choices for the second digit. Then there will be 2 choices for the third digit. Lastly there will be just 1 choice for the last digit.
The number of permutations becomes 2×3×2×1=12 .
Step-by-step explanation:
Answer:
#6The word has 9 letters with 2 Ms, 2Ts and 2Es
We need 2 Ts together, this reduces the number of positions by one.
The number of ways:
(9-1)!/2!2! = 8!/4 = 10080#7Digits 0, 1, 2, 3
Number should be greater than 2000, it means the number is:
2xxx ⇒ 3P3 = 3! = 6 waysor
3xxx ⇒ 3P3 = 3! = 6 waysTotal permutations:
2*6 = 12
