Find (4.2) x (1.6) by drawing an area diagram or using another method. Show your reasoning. Pleae answer this I really need help. PLZ
Answers
Answer:
the answer is 6.72
Step-by-step explanation:
Instead of a diagram you can do 4.2 times 1.6 and after you finishes doing that You put the decimal 2 times and you should get 6.72
The answer is 6.72
What is area diagram method?The length and width of a rectangle are defined by the factors being multiplied in an area model, which is a rectangular diagram used in mathematics to solve multiplication problems. Therefore, the area of the rectangle is the product. Subsequently, it is known as the "Region model for augmentation".
Given (4.2) x (1.6)
by area drawing method make an rectangle of 4.2 and 1.6 units and make perpendicular lines at distance of 4 units and 1 units on length and breadth, the rest distance will be 0.6 and 0.2 units, now we have four different rectangles as shown in image now find area of each rectangle and add all the areas.
area of rectangle 1 = 4 x 1 = 4
area of rectangle 2 = 1 x 0.2 = 0.2
area of rectangle 3 = 4 x 0.6 = 2.4
area of rectangle 4 = 0.2 x 0.6 = 0.12
total area = 4 + 0.2 + 2.4 + 0.12
total area = 6.72
Hence (4.2) x (1.6) = 6.72

How many pounds are in 6 tons, 200 pounds
Answers
Answer:
there are 12000 pounds in 6 tons
There are 12,200 pounds in 6 tons, 200 pounds .
To convert tons to pounds, we need to multiply the number of tons by the conversion factor of 2,000 pounds per ton .
A ton, also referred to as a short ton, is a unit of weight equal to 2,000 pounds .
Given that there are 6 tons and 200 pounds, we can calculate the total weight in pounds as follows :
6 tons * 2,000 pounds/ton + 200 pounds = 12,000 pounds + 200 pounds = 12,200 pounds .
Therefore, there are 12,200 pounds in 6 tons, 200 pounds .

LCD = 24
Equivalent Fractions with the LCD
1 1/2 = 36/24
3/8 = 9/24
5/6 = 20/24
3 = 72/24
Solution:
Rewriting input as fractions if necessary:
3/2, 3/8, 5/6, 3/1
For the denominators (2, 8, 6, 1) the least common multiple (LCM) is 24.
LCM(2, 8, 6, 1)
Therefore, the least common denominator (LCD) is 24.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
1 1/2 = 3/2 × 12/12 = 36/24
3/8 = 3/8 × 3/3 = 9/24
5/6 = 5/6 × 4/4 = 20/24
3 = 3/1 × 24/24 = 72/24

Answer:
Is B
Step-by-step explanation:
It's B because you use cups with the tablespoons to find the answer. 2 is cups, and it's on the numerator, and 1.5 is cups. It would have to be a numerator since you would only use denominators to plug in the value of tablespoons in the equation. v would be the denominator with 1.5 as the numerator since we are trying to find v with 1.5, so 1.5 has to be in the same fraction.

16. Hanna has a bag of 23 marbles. 5 marbles are red, 6 marbles are blue, and the rest
are pink. Abby takes out two pink marbles without replacing them. What is the
probability that the next marble he draws will be blue?
A. 10/21
B. 4/21
C. 2/7
D. 6/23
Answers
Answer:
C. 2/7
Step-by-step explanation:
When two pink marbles are taken without replacement then the total number of marbles in the bag are reduced to 21 marbles. So the blue marble, which are currently in total 6 marbles, is taken out of the total of 21 marbles. The calculation of which is done as below:
Probability of Next Marble to be blue
= Blue Marble / Total Marbles in the bag
= 6 / 21
= 2 / 7
Hence, the correct option is C. 2/7
