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?
Answer:
Step-by-step explanation:
"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

I am really confused on how to do this.
Step-by-step explanation:
Ok, so in a standard equation, there can’t be any fractions, so you would have to multiply everything by 3, making the equation 3y+3=2(x-8) (p.s. don’t multiply the parentheses, leave the numbers in them alone for now). Then, you would go through with the equation process: 3y+3=2x-16. You move the 3 over to the right to make 3y=2x-19. Move the x to the left, -2x+3y=-19. But, there is a problem. The first term of this equation can’t be negative(yes, in standard form, x has to come first). So, you have to multiply everything by -1, resulting in the answer 2x-3y=19. I hope this helps!(The format for a standard form equation is: Ax+By=C).

A line passes through the point (8,-1) and has a slope of -3/2
Answer:
y = -3/2 x +11Step-by-step explanation:
[tex](8,-1) = (x_1,y_1)\\\\m = -\frac{3}{2}[/tex]
Substitute values into point-slope form
[tex]y-y_1=m(x-x_1)\\\\y -(-1)=-\frac{3}{2} (x -8)\\\\y+1 = -\frac{3}{2}x+12\\\\y = -\frac{3}{2}x +12-1\\\\y =-\frac{3}{2}x +11[/tex]
The equation of line passes through the point (8, -1) will be;
⇒ y = - 3/2x + 11
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (8, - 1).
And, The slope of the line is,
⇒ m = - 3/2
Now,
Since, The equation of line passes through the point (8, -1).
And, Slope of the line is,
⇒ m = - 3/2
Thus, The equation of line with slope - 3/2 is,
⇒ y - (-1) = - 3/2 (x - 8)
⇒ y + 1 = - 3/2 (x - 8)
⇒ y + 1 = - 3/2x + 12
⇒ y = - 3/2x + 12 - 1
⇒ y = - 3/2x + 11
Therefore, The equation of line passes through the point (8, -1) with slope - 3/2 is,
⇒ y = - 3/2x + 11

Alexa transports flowers for Rolling Rosie's Garden Center. On her last route, she earned $450.80. If Alexa earned $0.40 for every mile, how far did she drive?
Answer:
1127 miles
Step-by-step explanation:
Since on her last route, she earned $450.80. And she earned $0.4 for every mile.
The amount earned divided by the amount earned per mile would give us the value of distance covered.
Thus,
distance covered = [tex]\frac{450.80}{0.40}[/tex]
= 1127
Thus, the distance covered by Alexa on he last route is 1127 miles.

4x+2=4 if x satisfies the equation above, what is the value of 2x+1
Answer:
2
Step-by-step explanation:
4x + 2 =4 => 4x = 2 => x = 0,5
if x =0,5 => 2x + 1 = 0,5.2 + 1 = 2
The values of "2x+1" will be "2".
The expression,
→ [tex]4x+2=4[/tex]
By subtracting "2" from both sides, we get
→ [tex]4x+2-2=4-2[/tex]
→ [tex]4x=2[/tex]
→ [tex]x = \frac{2}{4}[/tex]
→ [tex]x = 0.5[/tex]
By putting the value of "x" in the expression "2x+1", we get
→ [tex]2x+1 = 2(0.5)+1[/tex]
→ [tex]= 1+1[/tex]
→ [tex]= 2[/tex]

The supplementary angle of 136° is
Answer:
i think it is 44
Step-by-step explanation:
I am sorry if it is wrong
Answer:
a 44 degree angle
Step-by-step explanation:
The supplement of a 136 degree angle would be a 44 degree angle because:
136 + 44 = 180.
136 + x = 180
136 - 136 + x = 180 - 136
x = 44
Miranda and Jean are planning a trip together. They want to drive, but they're not sure whose car to take. Jean's car uses 5/12 gallons of gasoline to travel 12 1/2 miles. Miranda's car can go 20 5/7 miles on 5/7 gallons of gasoline. Whose car is more fuel efficient, and what is the car’s fuel efficiency in miles per gallon?
Answer:
most fuel efficient is Jean's car....it gets 30 miles per gallon
Step-by-step explanation:
Jean's car :
(12 1/2) / (5/12) =
(25/2) / (5/12) =
25/2 * 12/5 =
150/5 =
30 miles per gallon
Miranda's car :
(20 5/7) / (5/7) =
(145/7) / (5/7) =
145/7 * 7/5 =
145/5 =
29 miles per gallon
the 4th term of an ap is equal to 3 times the first term and the 7th term exceeds twice the third term by 1 find the first term and the common difference
We're given
a₄ = 3a₁
a₇ = 2a₃ + 1
Since these numbers form an arithmetic progression, we have for some fixed constant d
a₂ = a₁ + d
a₃ = a₂ + d = a₁ + 2d
a₄ = a₃ + d = a₁ + 3d
and so on, up to
a₇ = a₁ + 6d
Rewrite the given equations in terms of a₁, then solve for a₁ and d :
a₁ + 3d = 3a₁
a₁ + 6d = 2 (a₁ + 2d) + 1
2a₁ - 3d = 0
a₁ - 2d = -1
(2a₁ - 3d) - 2 (a₁ - 2d) = 0 - 2 (-1)
2a₁ - 3d - 2a₁ + 4d = 0 + 2
d = 2
a₁ + 3d = 3a₁
3 (2) = 2a₁
a₁ = 3

The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Tristan and two of his friends purchased tickets to a school play. Tristan paid for all the tickets with a $50.00 bill and received $23.00 in change.
Then the cost of the ticket will be
Cost = ($50 - $23) / 2
Cost = $27
If Tristan used a coupon for 25% off. Then the original price for all tickets will be
Original cost = $27 / 0.75
Original cost = $36
Then the cost of each ticket will be
Cost of each ticket = $36 / 2
Cost of each ticket = $18
