Answer The Following About Estimating 321/6.

Answers

Answer 1

Answer:

A) 300/6. B) Underestimate.

Step-by-step explanation:

321/6 is 53.5

300/6 is 50

and 360/6 is 60.

50 is closer to 53.5 than 60 is so the closest aproximation would be 300/6

Answer 2
53.5 is the correct answer without being simplified, 53.5 is closer to 50 than it is to 60.

Answers

The probability of selecting a yellow marble is #of yellow marbles/total # of marbles= 6/30 or .2 or 20%

If there are 300 marbles in the bag, a good estimate for the total number of red marbles in the bag is 90.

9/30=.3 = the percentage of red marbles

You can use the acronym PEMDAS to help you remember the Order of Operations in Maths.

Here's what it stands for:-

P - Parentheses

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

According to PEMDAS, the first operation is:-

Option A) 19-4

note:-

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)

Answer:

12,000, 900, 210, 18       4376x3=13128

Step-by-step explanation:

In the 1st box, you put the product of 4,000 x 3 = 12,000

In the 2nd, you put the product of 300 x 3 = 900

In the 3rd, you put the product of 70 x 3 = 210

In the 4th, you put the product of 6 x 3 = 18

Then you add your answers

12,000 + 900 + 210 + 18 = 13,128

The required partial product of 4376 × 3 is 13128.

What is the partial product?

In mathematics, partial products are defined as multiplying each digit of one integer by each digit of another number while keeping each digit's place value.

Here,
4376 × 3 = [4000 + 300 + 70 + 6] × 3

Simplifying using the distribution of 3,
= 4000 × 3 + 300 × 3 + 70 × 3 + 6 × 3
= 12000 + 900 + 210 + 18
= 13128

Thus, the required partial product of 4376 × 3 is 13128.

I buy a bed which normally costs £270 on a scheme where the price of the bed is increased by 60% but I only pay back £18 a month.
How long will it take to fully purchase the bed?

Answers

Answer:

it would take 2 years or 24 months

Step-by-step explanation:

60 percent of 270 is 162 add that to 270 and you get 432 divide that by 18 because that's what you're paying every month and you get 24 which is the numbe rof months it will take you to pay the bed off.

To cross check we can multiply 18 and 24 and you get 432.

Answer:

=432

Step-by-step explanation:

270-60%=162

162+270=432

432÷18=24

Triangle RST is made of points R(-10, 5.6), S(0, 7) and T(-6, -34).

If it is reflected across the x-axis to form triangle R'S'T', enter the coordinates of S'.

Answers

Answer:

S'= (0,-7)

Step-by-step explanation:

When reflecting coordinates across the x-axis, you would flip the sign of the y number (x,y) -> (x,-y). So in this case (0,7) -> (0,-7)

Find an equivalent expression for -3(2x+5)-(x-1)

Answers

Answer:

-7x - 14

Step-by-step explanation:

By simplifying the expression:

-3(2x+5) - (x - 1)

-6x-15 -x + 1

-7x - 14

Answer:

-7x - 14

Step-by-step explanation:

You can use the distributive property to find an equivalent expression.

Distribute -3 to 2x + 5.

(-3 × 2x) + (-3 × 5) = -6x + (-15) = -6x - 15

Distribute -1 to x - 1. (It is -1 because there is always a 1 in front of things like x = 1x and (x + 1) = 1(x + 1). 1 times anything equals the number it is multiplied by. There is a - sign in front of the parenthesis, which makes the invisible 1 a -1.)

(-1 × x) + (-1 × -1) = -x + 1

You can simplify the expression.

(-6x - 15) + (-x + 1) = -7x - 15 + 1 = -7x - 14

If a square has an area of 100ft², what is the length of one of the sides.

Step-by-step explanation:

This is because the area of a square can be found through the formula side x side or [tex]side^{2}[/tex]. You can find the length of one side by finding the square root of the area. You would get both a positive and negative value for the square root but you want a positive value because a length cannot be negative.

A drawer contains 5 red socks, 9 white socks, and 6 blue socks. Without looking, you draw out a sock and then draw out a second sock without returning the first sock.
Find P(blue, then blue).
Your answer:

Answers

P = Number of favourable outcomes ÷ Sum of total outcomes

So, Probability of drawing a blue sock is

Number of blue socks ÷ Number of total socks

= 6 ÷ 20

= 3 ÷ 10

= 0.3

Now as we have drawn a sock already the total number of socks in the drawer are 19

So, the probability of drawing a blue sock now will be :

= 6 ÷ 19
