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

Answer:

80 pages

Step-by-step explanation:

Divide 60 by 3 to get 20 because this is how many pages he can read in 1/4 hour. Then multiply that by 4 to get 80, which is how many pages he can read in a full hour.

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).

2 x 4 = 8

Answer:

4.9 ft

Step-by-step explanation:

Area of square = side squared

S² = A

Sub in 24 for A, then take square root of each side to find S.

S² = 24

S = sqrt (24)

= sqrt (4×6) - factorize

= 2(sqrt (6)) ft

≈ 4.9 ft

☆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

Answer: $573.50

Step-by-step explanation:

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)

Answer:

Step-by-step explanation:

The motion of a certain mass in a spring is described by:

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°.

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°

La medida del ángulo BOC pertenenciente al sistema de tres ángulos consecutivos es igual a 20°. [tex]\blacksquare[/tex]

Answer:

To find the unit rate, divide the numerator and denominator of the given rate by the denominator of the given rate. So in this case, divide the numerator and denominator of 70/5 by 5, to get 14/1, or 14 students per class, which is the unit rate.

Also, what are unit rates? A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.

The question is an illustration of conditional probability, and the value of the conditional probability P(A|B) is 0.38

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

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

Answer:

25

Step-by-step explanation:

The formula for the Pythagorean Theorem is:

[tex]\sqrt{a^2+b^2}=c[/tex]

Now,

A=7

B=24

7x7=49

24x24=576

Add,

576+49=625

Last,

Take the square root of 625

The square root of 625 is 25

c=25

To Check if the hypotenuse is correct:

[tex]a^2+b^2=c^2[/tex]

[tex]7^2+24^2=25^2[/tex]

7x7=49

24x24=576

25x25=625

49+576=625

625=625,

Therefore the hypotenuse is 25.

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.

====================================================

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:

Notice 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.

Then 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.
