Answer:
2 1/2 rolls
Step-by-step explanation:
rolls : walls = (1/2) : (1/10) = ? : (1/2) = 5/2 : 1/2 (multiply by 5, since 1/2 = 5/10)
It takes 5/2 rolls = 2 1/2 rolls to cover half the wall.
Answer:
[tex]2\frac{1}{2}[/tex] rolls of the wallpaper will cover half the wall
The correct option is (b) 2 1/2
Step-by-step explanation:
To determine the number of rolls of wallpaper that are needed to cover half (1/2) the wall,
From the question,
One-half of a roll of wallpaper covers 1/10th of a wall.
Hence, we are to determine the number of rolls of wallpaper that are needed to cover 5/10th of the wall. (NOTE: 5/10th of the wall = 1/2 the wall)
Now,
First, we will find the part of the wall that will be covered by one roll of the wallpaper
If one-half of the roll of wallpaper covers 1/10th of the wall.
Then, one roll (two halves) will cover 2 × 1/10th of the wall
= 1/5th of the wall
Hence one roll will cover 1/5th of the wall
Now, for the number of rolls that will cover half (1/2) the wall
If one roll of the wallpaper covers 1/5th of the wall
Then, [tex]x[/tex] rolls of the wallpaper will cover 1/2 of the wall
[tex]x =\frac{1/2 \times 1}{1/5}[/tex]
[tex]x =\frac{5}{2}[/tex]
[tex]x =2\frac{1}{2}[/tex]
Hence, [tex]2\frac{1}{2}[/tex] rolls of the wallpaper will cover half the wall

evaluate 207.3×0.04
Let's first just do the multiplication and ignore the decimal points.
2073 x 4 = 8292.
Now there are 3 decimal points we need to consider. So, that gives us an answer of 8.292

Answer: x=-7
Step-by-step explanation:
1) The angles of a triangle are equal to 180
2) Add your angles together and set them equal to 180 like this:
x+59+x+51+84=180
3) Combine like terms:
2x+ 194 =180
4) Subtract 195 from both sides:
2x+ 194 =180
- 194 -194
2x = -14
5) Divide by 2 on both sides
2x= -14
/2 /2
x= -7

Solve for x in simplest form. 4=4/3 (x−6)
Answer:
Solve for x in simplest form. 4=4/3 (x−6)
x=9
Step-by-step explanation:
Answer: x = 9
Step-by-step explanation: first you distribute the 4/3 to (x-6) by multiply 4/3 to x and to -6. Which will be 4=4/3x-24/3, then you simplify 24/3 which equal s 4=4/3x-8. Cancel the -8 by adding each side by 8, it'll be 4+8=4/3x-8+8. Which equals 12=4/3x. Then you divide each side by 4/3 to cancel the 4/3. 12/(4/3)=x & to divide a fraction you just need to cross multiply the number so it will be (12/1 x 3/4) = 36/4= 9 so x will be = 9.

I need help solving 8g+10=35+3g. Please help!!
Answer:
g = 5
Step-by-step explanation:
Step 1: Write out equation
8g + 10 = 35 + 3g
Step 2: Subtract 3g on both sides
5g + 10 = 35
Step 3: Subtract 10 on both sides
5g = 25
Step 4: Divide both sides by 5
g = 5

Answer:
I think the answer is E.
Step-by-step explanation:
-3 -4= -7 and that's less than nine.
if x was 3 it would be -7 + 3 = -4 which is still less than nine
if x was -11 it would be -7 -11 = -18 which is also lower than nine
if x was -3 it would be -7 -3 = -10 that's less than nine as well
Answer:
I only
Step-by-step explanation:
I) 3
9 > -3 - 4(3)
9 > -3 - 12
9 > -15
9 is great than -15 so the value of 3 works.
II). -11
9 > -3 - 4(-11)
9 > -3 +44
9 > 41
9 is actually less than 41 so the value of -11 does not work
III). -3
9 > -3 - 4(-3)
9 > -3 + 12
9 > 9
9 is equal to 9, not greater than so the value of 3 does not work

0.5 inches a month.
I believe you subtract 13 1/4 by 10 3/4 = 2 1/2.
Then you divide by 5.
Solve the two-step equation.Analyze the solution shown.
1. –|–x| = 7: given
2. |–x| = –7: multiplication property of equality
3. –x = 7 or –x = –7: definition of absolute value
4. x = –7 or x = 7: multiplication property of equality
5. Check: –|–(–7)| = 7, –7 ≠ 7
–|–7| = 7, 7 = 7
Negative times negative is positive.
Determine the flaws in the solution.
The multiplication property of equality in Step 2 should result in |x| = 7.
The definition of absolute value is applied incorrectly. There is no solution.
The reason in Step 4 should be the addition property of equality.
The multiplication property of equality in Step 4 should result in only x = 7.
In evaluating the solutions, the absolute value should be simplified first to get a positive value.
Answer:n evaluating the solutions, the absolute value should be simplified first to get a positive value.
The definition of absolute value is applied incorrectly. There is no solution.

The daily high temperatures, in degrees Celsius, for two weeks were recorded. The first week had a mean high temperature of 8 degrees Celsius and a mean absolute deviation (MAD) of 1 degree Celsius. Here is a list of the high temperatures, in degrees Celsius, for the second week. A. What is the mean temperature for the second week? B. What is the mean absolute deviation for the second week? C. Which week had greater variability in high temperature? Explain your reasoning. (When necessary, round all answers to the nearest hundredths place. Type all answers below.
Answer:
(A) The mean temperature for the second week is 4.86 degrees Celsius.
(B) The mean absolute deviation for the second week is 4.86 degrees Celsius.
(C) The second week had greater variability in high temperature.
Step-by-step explanation:
We are given that the daily high temperatures, in degrees Celsius, for two weeks were recorded. The first week had a mean high temperature of 8 degrees Celsius and a mean absolute deviation (MAD) of 1 degree Celsius.
Here is a list of the high temperatures, in degrees Celsius, for the second week;
5, 9, 7, 0, 3, 5, 5
(A) The mean temperature for the second week is given by;
Mean = [tex]\frac{\text{Sum of all data values}}{\text{Total number of values}}[/tex]
= [tex]\frac{5+9+7+0+3+5+5}{7}[/tex]
= [tex]\frac{34}{7}[/tex] = 4.86 degrees Celsius
(B) Mean absolute deviation for the second week is calculated as;
Firstly, subtracting mean from each data value;
| 5 - 4.86 | = 0.14
| 9 - 4.86 | = 4.14
| 7 - 4.86 | = 2.14
| 0 - 4.86 | = 4.86
| 3 - 4.86 | = 1.86
| 5 - 4.86 | = 0.14
| 5 - 4.86 | = 0.14
Now, we will find the mean of these deviations;
Mean absolute deviation = [tex]\frac{0.14+4.14 + 2.14+4.86+1.86+0.14+0.14}{7}[/tex]
= [tex]\frac{13.42}{7}[/tex] = 1.92 degrees Celsius
(C) The second week had greater variability in high temperature because it's mean absolute deviation is greater than that of first week. And also the mean absolute deviation tells us that on average how far the data values are from the mean.
X divided by 11 equals 10 divided by 12 what’s x
Answer:
x/11 = 10/12
x = 10*11/12= 55/6
Step-by-step explanation:
[tex] \huge \pink {\tt { \frac{x}{11} = \frac{10}{12}}} [/tex]
By cross multiplication, we get
12x = 110
or, x = 110/12 = 55/6

Faith lost 2 1/2 pounds in 10 days. If
Faith lost the same amount of pounds each
day, how much weight did Faith lose per
day?
Please help me
Answer:
1/4 pound
Step-by-step explanation:
2 1/2 divided by 10
=
1/4
or
5/2 divided by 10
=
1/4
Answer: 1/4 lbs
Step-by-step explanation:
To find weight lost each day, you have to divide total weight lost 2 1/2 lbs by total number of days 10.
(2 1/2) / 10 = 5/2 * 1/0 = 1/4 lbs lost each day
QUESTION 8 A motorboat leaves a harbor and travels at an average speed of 6 mph towards a small island. Two hours later, a cabin cruiser leaves the same harbor at an average speed of 12 mph toward the same island In how many hours after the cabin cruiser leaves the harbor will it be alongside the motorboat?
Answer:
2 hours
Step-by-step explanation:
Distance = rate × time
That is,
d=rt
Let
t = time (hours) cabin cruiser traveled
t + 2 = time (hours) motorboat traveled
motorboat = 6 mph
Cabin cruiser =12 mph
Motorboat distance
d=rt
d = 6(t + 2)
Cabin cruiser distance
d=rt
d = 12(t)
Equates the two distance
6(t + 2) = 12t
Open bracket
6t + 12 = 12t
12 = 12t - 6t
12 = 6t
Divide both sides by 6
t = 12 / 6
= 2
t = 2 hours
The cabin cruiser will be alongside the motorboat in 2 hours
ANSWER THIS QUESTION WITH WORKING PLEASE :>!!!
Step-by-step explanation:
y + 65°= 180° (Being co-interior angle)
y = 180° - 65°
y = 115°
Next we will find of the next co-interior angle which is A and D
(2x - 10)° + (3x + 20)° = 180° ( Same reason)
Now we will keep the like ones together.
2x° + 3x° - 10° + 20° = 180°
5x° + 10° = 180°
5x = 180° - 10°
5x = 170°
x = 170°/5
x = 34°
Now we need to find (2x - 10)° and (3x + 20)°
(2x - 10)°
=(2×34-10)°
=(68-10)°
=58°
(3x + 20)°
=(3×34-20)°
=(102-10)°
=92°
HELP!! -5/8 - (-4/3) = x What is x?
Answer:
x = [tex]\frac{17}{24}[/tex]
Step-by-step explanation:
Given
- [tex]\frac{5}{8}[/tex] - (- [tex]\frac{4}{3}[/tex] ) = x
Note that - (- [tex]\frac{4}{3}[/tex] ) = + [tex]\frac{4}{3}[/tex] , thus
- [tex]\frac{5}{8}[/tex] + [tex]\frac{4}{3}[/tex] = x
Multiply through by 24 ( the lcm of 8 and 3 ) to clear the fractions
- 15 + 32 = 24x
17 = 24x ( divide both sides by 24 )
[tex]\frac{17}{24}[/tex] = x
