Express the ratio as a unit rate.
4.5 miles in 25 minutes
Answer:
10 mins
Step-by-step explanation:
This is a fraction equal to
25 minutes ÷ 2.5 4.5
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 2.5
25 minutes ÷ 2.5
2.5 4.5 ÷ 2.5
=
10 minutes
1 4.5
=
10 minutes
4.5
= 10 minutes per 4.5

Name the place value to which each number was rounded 16.932 to 20
Hi :)
Rounded to the tenth place value.
16 to 20
Rounding to the nearest whole number means converting a number to an approximate value that is easier to use and remember. The place value to which 16.932 was rounded is 17.
What do you mean by nearest whole number?Rounding to the nearest whole number means converting a number to an approximate value that is easier to use and remember. Usually, decimal numbers and fractions are rounded to the nearest whole number with the help of the appropriate rules.
To round 16.932 to the nearest whole number consider the tenths’ value of 16.932, which is 9 and equal or more than 5. Therefore, we have to round up the whole number part of 16.932, 16, increases by 1 to 17, and the decimal point and all digits (.932) are removed.
16.932 rounded to the nearest whole number = 17
Therefore, The table ahead contains starting numbers close to 16.932 rounded to the nearest basic counting number.
Hence, the place value to which 16.932 was rounded is 17.

how do i express x^2-3x into the form of (x-m)^2+n. I will give brainliest to correct answer
Step-by-step explanation:
let's simply do the multiplications and then compare with the original.
(x-m)² + n
right ?
or is it
[tex] {(x - m)}^{2 + n} [/tex]
let's go for the first.
x² - 2mx + m² + n = x² - 3x
-2mx + m² + n = -3x
fun there we see two things :
-2m = -3
m = 3/2
and
m² + n = 0
(3/2)² = -n
9/4 = -n
n = -9/4
so our transformed expression looks like
(x - 3/2)² - 9/4

Help please! Find the area of the shape below. (Show work)
9514 1404 393
Answer:
292 yd²
Step-by-step explanation:
We can find the area of the remaining L shape by subtracting the area of the 21×22 rectangle at lower left from the 26×29 overall rectangle.
shape area = (26 yd)(29 yd) -(21 yd)(22 yd) = 754 yd² -462 yd²
shape area = 292 yd²
__
Additional comment
The area of a rectangle is the product of its length and width.
There are many ways the area of this shape can be calculated. The area can be divided into two rectangles, two trapezoids, three rectangles, and other ways.
If you cut up the given shape into smaller pieces, you will generally need to know the widths of the arms of the L. One of those is shown as 7 yd. The other is 26-21 = 5 yd.
Using the method we did, we only needed the dimensions shown on the figure.

Pick a bin from each row. Subtract to find how many more bottles are in the bin from the top row than the bin from the bottom row
Bin A 15 bin B 12 bin C 13
Bin D 9 binE 7 bin F 8
How do you solve this problem
Answer:
Step-by-step explanation:
The number of Bins in the first row is 16 higher than in the second row.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given first and second rows are:-
Bin A 15 bin B 12 bin C 13
Bin D 9 binE 7 bin F 8
The total number of the bins first row = Bin A + bin B + bin C
The total number of the bins first row = 15 + 12 + 13 = 40
The total number of the bins in the second row = Bin D + Bin E + Bin F
The total number of bins in the second row = 9 + 7 + 8 = 24
Therefore, the number of Bins in the first row is 16 higher than in the second row.
