Answer:
diameter-- last picture on right side
radius-second last picture on right side
πd=2πr
2r=d/2
Step-by-step explanation:
diameter is a line segment that goes through the center of a circle
this will match to the last image on the right side
radius is half of the diameter or from a point on the outer edge of the circle to the center
this will match to the second one on the right side
πd-- d=2*radius
2πr
2r=d/2
because radius is half of the diameter

Dalia is painting her room. After painting 1/10 of her room, Dalia has used 1/2 of a can of paint. Select all of the true statements.
1. each can of paint will cover 1/20 of Dalia's room
2. painting 1/2 of Dalia's room requires 10 cans of paint
3. Dalia's entire room requires 20 cans of paint
4. 3 cans of paint will cover 60% of Dalia's room
5. Dalia's entire room requires 5 cans of paint
THANK YOU WILL ADD BRAINLIEST FOR RIGHT ANSWER
Answer:
4. 3 cans of paint will cover 60% of Dalia's room
5. Dalia's entire room requires 5 cans of paint
Step-by-step explanation:
If Dalia has painted 1/10 of her room with 1/2 can of paint, then she will paint 2/10 of her room with 1 can of paint (since there are 2 halves in a whole).
2/10 = 1/5 ⇒ 1 can of paint covers 1/5 of the room.
Therefore, to paint the entire room, she will need 5 cans of paint.
60% of 5 cans of paint = 0.6 × 5 = 3
Therefore, 3 cans of paint will cover 60% of the room.
Steps to solve an equation are shown below. Which properly justifies step 4? Given: 2x + 9 = 4x + 15
Answer:
The answer is
→ No property
Step-by-step explanation:
Given equation: [tex]2x + 9 = 4x + 15[/tex]
What were supposed to do: Which properly justifies step 4.
Solve:
[tex]2x + 9 = 4x + 15[/tex]
Step 1: We must subtract 4x on both sides.
[tex]2x+9-4x=4x+15-4x[/tex]
[tex]= -2x+9=15[/tex]
Step 2: We must subtract 9 on both sides.
[tex]-2x+9-9=15-9[/tex]
[tex]= -2x=6[/tex]
Step 3: We must divide both sides by -2.
[tex]\frac{-2}{2} = \frac{6}{-2}[/tex]
[tex]= x = -3[/tex]
Result:
[tex]x=-3[/tex]
There is no Step 4.

01. Se tienen los angulos consecutivos AOB, BOC y COD. se cumple m& AOC=125° m
La diferencia entre los ángulos AOB y COD del sistema de tres ángulos consecutivos es igual a 25°.
La medida del ángulo BOC pertenenciente al sistema de tres ángulos consecutivos es igual a 20°.
Cómo analizar tres ángulos consecutivos
Por la geometría Euclídea conocemos que un conjunto de ángulos cuando comparten entre cada par de ángulos vecinos comparten el mismo vértice y la misma semirrecta.
De acuerdo con el enunciado, tenemos las siguientes condiciones:
∠AOB + ∠BOC = 125° (1)
∠BOC + ∠COD = 100° (2)
Por (1) y (2) tenemos las siguiente identidad:
∠AOB - 25° = ∠COD
∠AOB - ∠COD = 25°
La diferencia entre los ángulos AOB y COD del sistema de tres ángulos consecutivos es igual a 25°. [tex]\blacksquare[/tex]
En el segundo caso, tenemos el siguiente sistema:
∠AOB = ∠BOC + ∠COD (3)
∠AOB + ∠BOC - ∠COD = 40° (4)
Por (3) y (4) tenemos la siguiente identidad:
2 · ∠BOC = 40°
∠BOC = 20°

☆Explanation:
¤ We that area of a Rectangle = length × breadth
¤ Here, it is said to find the area of the given figure.
Now,
Area of first Rectangle = length × breadth
= 9 cm × 4 cm
= 36 cm²
Again,
Area of the second Rectangle = length × breadth
= 14 - 4 × 5
= 10 × 5
= 50 cm²
Finally,
Area of the figure = Area of first Rectangle + Area of second Rectangle.
= 36 cm² + 50 cm²
= 86 cm²

to fill Jasmine's bucket?
Hi!
Your answer is 8 1-quart containers.
There are 4 quarts in a gallon.
If there is a 2-gallon bucket, and she needs to fill it using 1-quart containers, we simply multiply the number of quarts in a gallon (4) by the number of gallons total (2).

The question is an illustration of conditional probability, and the value of the conditional probability P(A|B) is 0.38
How to determine the value of the probability expression?The question is incomplete, as the required parameters are not given.
So, I will give a general explanation.
The question is an illustration of conditional probability
What is a conditional probability?The conditional probability is used to determine the probability of an event, given that another independent event has already occurred.
The conditional probability is calculated using:
P(A|B) = n(A and B)/n(B)
Assume the following parameters
n(A and B) = 9
n(B) = 24
The equation to calculate the probability expression is represented as:
P(A|B) = n(A and B)/n(B)
Substitute the assumed values
P(A|B) = 9/24
Evaluate the expression
P(A|B) = 0.38
Hence, the value of the conditional probability P(A|B) is 0.38

Which of the following graphs best represents the solution to the pair of equations below? y = −2x + 2 y = 2x + 2 A coordinate plane is shown with two lines graphed. One line passes through the y axis at 2 and the x axis at 1. The other line passes through the y axis at negative 2 and the x axis at 1. The lines intersect at 1 comma 0. A coordinate plane is shown with two lines graphed. One line passes through the y axis at negative 2 and the x axis at 1. The other line passes through the y axis at 2 and the x axis at negative 1. The lines are parallel and do not intersect. A coordinate plane is shown with two lines graphed. One line passes through the y axis at 2 and the x axis at 1. The other line passes through the y axis at 2 and the x axis at negative 1. The lines intersect at 0 comma 2. A coordinate plane is shown with two lines graphed. One line passes through the y axis at 2 and the x axis at negative 1. The other line passes through the y axis at negative 2 and the x axis at negative 1. The lines intersect at negative 1 comma 0.
The lines are
i) y=-x+6
ii) y=2x-3
The solution of the system of equations is found by equalizing the 2 equations:
-x+6=2x-3
-2x-x=-6-3
-3x=-9
x=-9/(-3)=3
substitute x=3 in either i) or ii):
i) y=-3+6=3
ii) y=2(3)-3=6-3=3
(the result is the same, so checking one is enough)
This means that the point (3, 3) is a point which is in both lines, so a solution to the system.
In graphs, this means that the lines intersect at (3, 3) ONLY
Answer: The graph where the lines intersect at (3, 3)

How I got that answer:
The interval 0 < t < 30 has the midpoint of 15 since (0+30)/2 = 15
The interval 30 < t < 60 has the midpoint 45 because (30+60)/2 = 45
We add up the endpoints and then divide by 2 to get the midpoint.
Repeat this for each of the intervals mentioned.
From top to bottom, the midpoints are:
154575105Notice we add 30 to each midpoint to get the next one. This is directly due to the fact that each interval is 30 units wide (eg: 90-60 = 30).
Multiply each midpoint by the corresponding frequency for a given row.
15*7 = 10545*27 = 121575*12 = 900105*4 = 420Then add up those products.
105+1215+900+420 = 2640
Lastly, we divide this over the sum of the frequencies 7+27+12+4 = 50 to get 2640/50 = 52.8
The average time spent on homework is estimated to be about 52.8 minutes
Note that the majority of the the students (27) are in the 30 < t < 60 interval, so the mean of 52.8 fits this interval perfectly. It's closer to the right endpoint of the interval due to the fact the other 12+4 = 16 students are above this, and they make up the second most majority compared to the 27.
The reason why 52.8 is an estimate rather than the actual mean is because we are estimating each interval by picking out the midpoint each time. The midpoint is at the direct center, so it's the best guess we can do.
