Subtracting 3 xy2 from 8 xy2 gives the same result as the expression
Reset 3xy^2 - xy^2
-7xy^2 - 2xy^2
7xy^2 - 2xy^2
Answer:
7xy^2 - 2xy^2
Step-by-step explanation:
Subtracting 3xy² from 8xy² is 8xy² - 3xy² = 5xy²
And 7xy^2 - 2xy^2= 5xy²

Please Help! A bag contains four green marbles and five yellow marbles. You randomly select three marbles. What is the probability that all three marbles are green when (a) you replace each marble before selecting the next marble, and (b) you do not replace each marble before selecting the next marble? Write each probability as a decimal rounded to the nearest thousandth. Then compare the probabilities.
Answer:
A. 0.088
B. 0.048
C. 1.83 times
Step-by-step explanation:
From the question given above, the following data were obtained:
Green (G) = 4
Yellow (Y) = 5
Total = 4 + 5 = 9
A. Determination of the probability of selecting three green marbles with replacement.
Green (G) = 4
Yellow (Y) = 5
Total = 9
P(1st G) = 4/9
P(2nd G) = 4/9
P(3rd G) = 4/9
P(all G) = P(1st G) × P(2nd G) × P(3rd G)
P(all G) = 4/9 × 4/9 × 4/9
P(all G) = 64/729
P(all G) = 0.088
B. Determination of the probability of selecting three green marbles without replacement.
Green (G) = 4
Yellow (Y) = 5
Total = 9
P(1st G) = 4/9
P(2nd G) = 3/8
P(3rd G) = 2/7
P(all G) = P(1st G) × P(2nd G) × P(3rd G)
P(all G) = 4/9 × 3/8 × 2/7
P(all G) = 24/504
P(all G) = 0.048
C. Comparing probability of replacement and without replacement.
P(all G with replacement) = A = 0.088
P(all G without replacement) = B = 0.048
A/B = 0.088/0.048
A/B = 1.83
Cross multiply
A = 1.83 × B
Thus,
P(all G with replacement) = 1.83 × P(all G without replacement)

Given:
In triangle [tex]ABC,m\angle A=138^\circ,c=19,a=29[/tex].
To find:
The [tex]m\angle C[/tex].
Solution:
According to the law of sines:
[tex]\dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]
Taking [tex]\dfrac{\sin A}{a}=\dfrac{\sin C}{c}[/tex], we get
[tex]\dfrac{\sin 138^\circ}{29}=\dfrac{\sin C}{19}[/tex]
[tex]\dfrac{0.66913}{29}\times 19=\sin C[/tex]
[tex]0.4383959=\sin C[/tex]
Taking sin inverse on both sides, we get
[tex]\sin{-1}0.4383959=C[/tex]
[tex]26.001577^\circ=C[/tex]
[tex]C\approx 26^\circ[/tex]
Therefore, the correct option is b.

A packing box measures 36 centimeters by 14 centimeters by 20 centimeters. What is the volume of the box?
Answer:
1000
Step-by-step explanation:
first you times 36 by 14 witch equals 54. Then do 54 x 20 = 1000 the 4 is gone because of the zero. So your answer should be 1000
Beau´s aquarium has 12 fish.Five of the fish are guppies. Which equation can be used to be determine the number of other fish in his aquirium
Answer:
12 = 5 + x
Step-by-step explanation:
Total fish in the aquarium = 12
Number of guppies fish = 5
Number of other fishes = x
Total fish in the aquarium = Number of guppies fish + Number of other fishes
12 = 5 + x
Subtract 5 from both sides
12 - 5 = 5 + x - 5
7 = x
x = 7
Number of other fishes = x = 7
Alec keeps his pens, pencils, and erasers in a plastic box that is shaped like a rectangular prism. Alec's box is 25 centimeters long, 6 centimeters wide, and 4 centimeters tall. What is the volume of Alec's plastic box?
Answer:
624 square centimeters
Step-by-step explanation:
You must do 25x6x4 to get the volume. So you must multiply the length, height and width to get the volume.

=> B) The amount of popcorn that fits in a particular container.
Explanation:=> The amount of space that a substance or object occupies, or that is enclosed within a container is known as volume. The first & third option measures the surface area while the fourth option measures the distance covered. Thus, the second option (b) is the correct answer.
[tex] \infty \infty \infty [/tex]
Answer:
B. The amount of popcorn that fits in a particular container.
Step-by-step explanation:
Volume is the amount of space that is inside a three dimensional shape. In other words we need a box/container that has empty space in it. That space is the volume. Knowing this we can start eliminating answer. First we can eliminate answer D. This answer makes no sense when comparing it to what is needed for volume. Answer D has to do with distance. Then we can eliminate answer C. This answer does can not work because it says "square inches". This means that it is either the area of a two dimensional shape or it could be the outside of a three dimensional shape. Answer A. is like answer C. It is the outside of a shape and not the inside. That leaves us with answer B. Answer B says "that fits in a particular container". From this we can see that they are fitting something inside a container. These are the key words for volume.

A rental car agency charges $220.00 per week plus $0.25 per mile to rent a car. How many miles can you travel in one week for $400.00?
The number of miles you can travel in one week for $400.00 is (Type a whole number.)
Plz help
Answer:
The number of miles you can travel in one week for $400.00 is 720 miles
Step-by-step explanation:
220 +0.25m = 400
0.25m = 180
m= 180/0.25
m= 720

Find the value of c that makes x2 + 6x + c a perfect square. Then write the trinomial as a perfect square.
Hi there!
[tex]\large\boxed{c = 9, (x +3)^2}[/tex]
To find the value of c, we can say:
ax² + bx + c
(b/2)² = c
Therefore:
(6/2)² = 3² = 9
Rewrite the trinomial:
x² + 6x + 9
To write as a binomial, take the square root of c:
√9 = 3
Thus:
(x + 3)² = x² + 6x + 9

find the length of side x in simplest radical form with a rational denominator
Answer:
x = √(10)/2
Step-by-step explanation:
Here, we want to get the measure of the side marked x
what we have is an isosceles right triangle since the two acute angles of the right triangle are 45 degrees each
Hence, the other last side will measure x too
Mathematically, according to Pythagoras’; the square of the hypotenuse equals the sum of the squares of the two other sides
Thus;
x^2 + x^2 = (√5)^2
2x^2 = 5
x^2 = 5/2
x = √(5/2)
x = √5/√2
Rationalizing the denominator;
x = (√2 * √5)/(√2 * √2)
x = √10/2
