"A rectangular room measures 3.8 meters in length and 4.9 meters in width. Jana multiplies both numbers together. Which expression would be best for her to use to check the reasonableness of her decimal multiplication?"
given that
the length is 3.8m long and,
width is 4.9m wide
The expression for the area is
Area= length * width
Area= 3.8*4.9
Area= 18.62 m^2
Therefore the expression best for her to use to check the reasonableness of her decimal multiplication is the area which is 18.62 m^2

Complete question :
The regular price of an item at a store is p dollars. The item is on sale for 20% off the regular price. Some of the expressions shown below represent the sale price, in dollars, of the item. Expression A: 0.2p Expression B: 0.8p Expression C:1 - 0.2p Expression D: p - 0.2p Expression E: p - 0.8p Which two expressions each represent the sale price of the item?
Answer:
Expression B: 0.8p ;
Expression D: p - 0.2p
Step-by-step explanation:
Given that:
Regular price = p dollars
Discount on price = 20%
Hence,
sale price = regular price - discounted price
Discounted price = 0.2 * p = 0.2p
Sale price = p - 0.2p
Or
Sale price = p - 0.2p = 0.8p

A recipe uses 4 cups of milk to make 12 servings. If the same amount of milk is used for each serving, how many servings can be made from three gallons? How many cups will you need to find the number of servings for?
Answer:
144 servings
Step-by-step explanation:
1 gallon = 16 cups
2 gallons = 32 cups
3 gallons = 48 cups
Using ratio
4 cups of milk : 12 servings
48 cups of milk : x servings
4 : 12 = 48 : x
4 / 12 = 48 / x
Cross product
4 * x = 12 * 48
4x = 576
x = 576 / 4
= 144
x = 144 servings
3 gallons of milk = 48 cups of milk = 144 servings

Examine the sequence of values below. 653, 1261, 1869, 2477, 3085, 3693 Which algebraic expression represents the nth value in this sequence?
Answer: [tex]a_{n}=653+(n-1)608[/tex]
Step-by-step explanation: This sequence of numbers is an arithmetic progression: a sequence of numbers in which the last number is the previous number plus a constant factor.
For example, the sequence:
653 1261 1869 2477 3085 3693
if you subtract each term with its previous number, the result will be 608:
1261 - 653 = 608
1869 - 1261 = 608
...
33693 - 3085 = 608
For a general arithmetic progression, the nth value is
[tex]a_{n}=a_{0}+(n-1)r[/tex]
where
[tex]a_{n}[/tex] is the wanted value
[tex]a_{0}[/tex] is the first value
n is number of terms or values
r is constant factor
For the sequence above, nth value is:
[tex]a_{n}=653+(n-1)608[/tex]
The algebraic expression for the nth value in this sequence is [tex]a_{n}=653+(n-1)608[/tex].

Answer:
Company B will charge less to move her items
Step-by-step explanation:
A. Expression that represents the rate each company charges
Let x = number of pounds moved
Company A = 230 + 3.40x
Company B = 270 + 2.80x
B. If Sheila has a total of 1,250 pounds of household items
Substitute x = 1,250
Company A = 230 + 3.40x
= 230 + 3.40(1,250)
= 230 + 4,250
= 4,480
Company A = $4,480
Company B = 270 + 2.80x
= 270 + 2.80(1,250)
= 270 + 3,500
= 3,770
Company B = $3,770
Company B will charge less to move her items

Which equation describes the line through the points (4,-3) and (5,0)
Answer:
y = 3x - 15
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, - 3) and (x₂, y₂ ) = (5, 0)
m = [tex]\frac{0+3}{5-4}[/tex] = 3 , thus
y = 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (5, 0 ), then
0 = 15 + c ⇒ c = 0 - 15 = - 15
y = 3x - 15 ← equation of line

On a map, 1 inch equals 20 miles. If two cities are 3 inches apart on the map, how far are they actually apart?
Answer: 60 miles
Step-by-step explanation: You multiply 3 by 20 because 1 inch is 20
Answer:
The cities are actually 60 miles apart.
Step-by-step explanation:
Take the scale factor 1 inch = 20 miles and multiply it by the number of inches given.
3 × 1 inch and 3 × 20 miles 3 × 20 = 60
3 inches represents 60 miles
Debra has a rectangular garden. The length is six less than twice the width. The perimeter of her garden is 90 meters. What is the width and the length of the garden?
Answer:
width = 17 meters
length = 28 meters
Step-by-step explanation:
Since we are told that the length is equal to 6 less than twice the width, and we know that the perimeter of a rectangle is calculated by adding all the sides together, then we can create the following formula to calculate both the length (l) and width (w).
l = 2w-6
l + l + w + w = 90 ... substitute l with its formula
(2w-6) + (2w-6) + w + w = 90 ... combine like terms
6w - 12 = 90 ... add 12 on both sides
6w = 102 ... divide both sides by 6
w = 17 meters
Now that we know the width we can plug it into the length formula and solve for the length
l = 2w - 6
l = 2(17) - 6
l = 34 - 6
l = 28 meters
