The perimeter of a rectangle with a length of 10 units which equation can be used to find the width of the rectangle
Answers
Answer:
2w + 20 = 55
Step-by-step explanation:
Here is the full question
The perimeter of a rectangle with a length of 10 units is 55 units. Which equation can be used to find the width, w, of the rectangle?
w + 10 = 55
w + 20 = 55
2w + 10 = 55
2w + 20 = 55
The perimeter of a rectangle's formula is = 2 ( length + breadth)
from the question ,
perimeter is 55 and length is 10
2(10 + w) = 55
20 + 2w = 55

Answer:

Step-by-step explanation:
what are the coordinates of A after reflecting across the line x = 3? (2, 3)
(3, 2) (3, 4) (3, -2)
Answers
Answer:
Here we can not see point A, so i will answer in a general way.
Let's suppose that point A is (a, b)
Now, if we do a reflection over a given line, the (perpendicular) distance between our original point to the line is the same as the distance between the reflected point and the line.
So for example if we have the point (x, y) and we do a reflection over the line x = k.
The distance between our point and the line is:
x - k
So the new point must be also at a distance of (x - k) from line x = k.
The only other point that meets this condition is (k - (x - k), y) = (2k - x, y)
Now remember that point A is (a, b)
And we do a reflection over x = 3
The distance between our point and the line is:
D = I(a - 3)I
Then the reflection will be:
(3 - (a - 3), b) = (6 - a, b)
Where (a, b) where the original coordinates of point A.

Harper bought 8.6 cm of fabric. She used 2.8 meters making a pilow . How many cm of fabric does she have left
Answers
Answer:
5.8 cm fabric is left
Step-by-step explanation:
Fabric bought = 8.6 cm
Used fabric to make pillow = 2.8 m
We need to find the amount of left fabric.
Left fabric = total fabric - used fabric
= 8.6 cm - 2.8 cm
= 5.8 cm
Hence, 5.8 cm fabric is left.

Write in slope intercept form.
15x − 4y = 11
Answers
Answer:
y = 15/4x - 11/4
Step-by-step explanation:
Slope-intercept form of the line 15x - 4y = 11 is y = (15/4)y + 11/4.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
We know the equation of a line in slope-intercept form is y = mx + b.
∴ 15x − 4y = 11 can be written as - 4y = - 15x + 11 ⇒ y = (15/4)y + 11/4.

Two cars leave town at the same time and travel in opposite directions. Speed of car A is 12 km/h more than car B. They are 312km apart after 4 hours. Find the speed of each car.
Answers
Answer:
Speed of car B is 33 km/h and speed of car A is [tex]45\,\,km/h[/tex]
Step-by-step explanation:
Let speed of car B be [tex]x[/tex] km/h
Speed of car A is 12 km/h more than car B.
Therefore,
Speed of car A = [tex](12+x)[/tex] km/h
Distance = Speed × Time
Distance travelled by car A in 4 hours = [tex]4(12+x)[/tex] km = [tex](48+4x)[/tex] km
Distance travelled by car B in 4 hours = [tex]4x[/tex] km
Also, cars A and B are 312km apart after 4 hours.
[tex]48+4x+4x=312\\48+8x=312\\8x=264\\\\x=\frac{264}{8}\\\\x=33\,\,km/h[/tex]
Speed of car B is 33 km/h and speed of car A is [tex]12+x=12+33=45\,\,km/h[/tex]

Satish's register shows a deposit on February 4 in the amount of $150.00, an atm withdrawal on February 5 in the amount of $180, and another deposit on February 7 in the amount of $225.56. What should Satish's balance in his register be? A. $610.82, B.$792.91, C.$910.82, or D.$947.14
Answers
Answer:
Balance = $195.56
Step-by-step explanation:
Credit:
Feb 4 deposit = $150.00
Feb 7 deposit = $225.56
Total credit = $375.56
Debit:
Feb 5 ATM withdrawal = $180
Total Debit = $180
Balance = credit - debit
= $375.56 - $180
= $195.56
Balance = $195.56
The answer is not included in the option. It is either the options are not correct or the values in the question are not correct. Please recheck
Satish's balance in his register would be $195.56
Equation
Equation is an expression used to show the relationship between two or more numbers and variables.
Credit:
Feb 4 deposit = $150.00
Feb 7 deposit = $225.56
Total credit = $150 + $225.56 = $375.56
Debit:
Feb 5 withdrawal = $180
Total Debit = $180
Balance = $375.56 - $180 = $195.56

Calculate the area and perimeter of the polygon.
Answers
Answer:
a) P = 24.2 units
b) A = 13.9 square units
Step-by-step explanation:
Perimeter = [tex]\sqrt{10}[/tex]+[tex]\sqrt{10}[/tex] + 4[tex]\sqrt{5}[/tex] + 4[tex]\sqrt{5}[/tex]
P = 2[tex]\sqrt{10}[/tex] + 8[tex]\sqrt{5}[/tex] which is approx 24.2 units
To find area you must find the height which can be done using the Pythagorean Theorem (we can do this for the small triangle on the left):
([tex]\sqrt{5}[/tex]²) + h² = ([tex]\sqrt{10}[/tex]²)
5 + h² = 10
h² = 5
h = [tex]\sqrt{5}[/tex]
A = bh
A = [tex]\sqrt{5}[/tex] (4 + [tex]\sqrt{5}[/tex])
A = 4[tex]\sqrt{5}[/tex] + 5 which is approx 13.9 square units
