The shaded rectangle shown below is a scale drawing of a rectangle whose area is 288 square feet. What is the scale factor of the drawing? (Note: Each square on the grid has a length of 1 unit.)
Answer:
2881
Step-by-step explanation:
Answer:
1 sq.unit = 9 sq.feet
Step-by-step explanation:
Length of shaded rectangle = 6 square on grid
We are given that Each square on the grid has a length of 1 unit.
So, Length of shaded rectangle = 6 units
Breadth of shaded rectangle = 4 square on grid = 4 units
Area of shaded rectangle = [tex]Length \times Breadth = 8 \times 4 = 32 units^2[/tex]
We are given that area of original square = 288 sq.feet
32 sq.unit = 288 sq.feet
1 sq.unit = [tex]\frac{288}{32} =9[/tex]
So, 1 sq.unit = 9 sq.feet
Hence Scale is 1 sq.unit = 9 sq.feet
Jordan will hike the trail shown at a rate of 4 mi/h. Write a linear equation to represent the distance Jordan still has to walk after x hours.What does the y-intercept of the equation
represent?
What we know:
Start of trail:
0 miles
End of trail:
25 miles
Answer:
Y=25-4x
Y means the distance Jordan still has to walk after x hours
Step-by-step explanation:
Answer:
y = 25 - 4*x
The y-intercept represents the total distance Jordan has to walk
Step-by-step explanation:
By Definition, speed = distance/time. We are interested in distance, then:
distance = speed*time
Calling x the hours of walking, and knowing that his speed is 4 mi/h, then:
distance = 4*x
The trail length is 25 miles, so if he walked 1 mile, 25 - 1 = 24 miles are left, in general:
y = 25 - 4*x
where y is the distance Jordan still has to walk.
The y-intercept is found replacing with x = 0, then:
y = 25 - 4*0
y = 25
which represents the total distance Jordan has to walk

Answer:
a. 276 vehicles
Step-by-step explanation:
7⁄10[13½] + 3⁄10[20] + 3v - 3 = [4][5280]
[tex] \frac{10323}{( \frac{7}{10})(13 \frac{1}{2}) + ( \frac{3}{10})(20) + 3} = v \\ \\ \frac{10323}{9 \frac{9}{20} + 6 + 3} = v \\ \\ \frac{10323}{9 \frac{9}{20} + 9} = v \\ \\ \frac{10323}{18 \frac{9}{20}} = v \\ \\ 559 \frac{21}{41} = v[/tex]
Now, we check to see which answer choice this quantity is closer to. Obviously, we will take 896 and 276:
-559 21⁄41 + 896 = 336 20⁄41
559 21⁄41 - 276 = 28221⁄41 → we take this number
* 559 21⁄41 is much more closer to 276 than it is to 896.

Find the length of segment CD with points C(2,2) and D (-1,8)
A. 8.1
B. 5.2
C. 4.3
D. 6.7
Answer:
D
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = C(2, 2) and (x₂, y₂ ) = D(- 1, 8)
CD = [tex]\sqrt{(-1-2)^2+(8-2)^2}[/tex]
= [tex]\sqrt{(-3)^2+6^2}[/tex]

How much does 8.20 X 10-3dm3 (1dm3 = 1L) sample of aluminum weigh in grams?
centimeters?
Answer:
8.20 grams ; 8.20 cm³
Step-by-step explanation:
At first convert it to m³ from dm³
we know,
1 dm³ =10⁻³ m³
∴ 8.20 X 10⁻³dm3 = 8.20 X 10⁻³ x 10⁻³ m³
=8.20 X 10⁻⁶ m³
m³ to gram :
1 m³ = 10⁶ grams
∴ 8.20 X 10⁻⁶ m³ = (8.20 X 10⁻⁶x10⁶) grams
= 8.20 grams
m³ to cm³ :
1m³ = 10⁶ cm³
∴8.20 X 10⁻⁶ m³ = (8.20 X 10⁻⁶ x 10⁶) cm³
=8.20 cm³
Note:
1 cm³ = 1 gram
Find the value of W and please show step by step working out
Answer:
w = 60
Step-by-step explanation:
Given
[tex]\frac{4w}{10}[/tex] + 28 = 52 ( subtract 28 from both sides )
[tex]\frac{4w}{10}[/tex] = 24
Multiply both sides by 10 to clear the fraction
4w = 240 ( divide both sides by 4 )
w = 60

Which equations represent the line that is perpendicular to the line 5x - 2y = -6 and passes through the point
(5, -4)? Select three options.
y=-2 X-2
2x +hoy = -10
L2x - 5y = -10
y+ 4 = _{(x - 5)
y- 4 = 5(x+5)
Answer
See below
Step-by-step explanation:
The given line has equation
[tex]5x - 2y = - 6[/tex]
The slope intercept form is
[tex]y = \frac{5}{2} x + 3[/tex]
The slope of this line is
[tex] m = \frac{5}{2} [/tex]
The line perpendicular to this line has slope
[tex] - \frac{2}{5} [/tex]
If this line passes through (5,-4), the point-slope form is
[tex]y + 4 = - \frac{2}{5} (x - 5)[/tex]
The slope-intercept form is
[tex]y = - \frac{2}{5} x- 2[/tex]
The standard form is
2x+5y=-10

Esther works for a marketing company. She earns $12 per hour, and she gets $50 travel allowance every month. Which linear equation could be used to find her monthly pay rate?
Answer:
y = 12x + 50
Step-by-step explanation:
Given,
The fixed amount of monthly allowance = $ 50,
Also, the earning per hour = $ 12,
If she works x hours in a month,
Then her total earning in x hours = 12x,
Also, total earning for a month ( say y ) = earning for x hours + fixed allowance
⇒ y = 12x + 50
Which is the required linear equation.
Answer:
y = 12x + 50

model the number 5.55 on the place value chart
Answer:
Here's what I get
Step-by-step explanation:
Each digit in a number has a place value, based on its distance from the decimal point.
The value of a digit is the digit multiplied by its place value.
The place value of a digit increases by a factor of 10 as we move left on the place value chart and decreases by a factor of 10 as we move right.
Numbers to the left of the decimal point increase in the order: ones, tens, hundreds, thousands, etc.
Numbers to the right of the decimal point decrease in the order: tenths, hundredths, thousandths, etc.
So, we put the digits of 5.55 on the chart according to their place value.

In mathematical operations, the direction can be from left to right or right to left, but in general, operations are performed according to the BODMAS/PEDMAS rule, which directs us from left to right.
Explanation:In mathematical operations, the direction can be either from left to right or right to left, this largely depends on the specific operation field. However, in general, mathematics operations follow the BODMAS/PEDMAS rule, and the operations are performed from left to right.
The rule simply states: Brackets, Orders (exponential, square roots, etc.), Division and Multiplication (from left to right), Addition and Subtraction (from left to right). If you have, for example, a problem like 3 + 4 * 2, you would first perform the multiplication (4*2 = 8), then add the answer to 3, for a total of 11.

Naoya read a book cover to cover in a single session, at a rate of 555555 pages per hour. After 444 hours, he had 350350350 pages left to read.
Let yyy represent the number of pages left to read after xxx hours.
Complete the equation for the relationship between the number of pages left and number of hours.
Answer:
[tex]y=-55x+570\\[/tex]
Step-by-step explanation:
Ah im too lazy to type out everything
The equation for the relationship between the number of pages left and number of hours is y = 555x - 555 * 444.
The relationship between the number of pages left to read (y) and the number of hours (x) can be represented by a linear equation.
Naoya reads at a rate of 555 pages per hour, which means he reads 555 pages in one hour. In 444 hours, he read 555 * 444 pages.
So, the equation for the relationship between the number of pages left and the number of hours is:
y = 555x - 555 * 444
In this equation:
- y represents the number of pages left to read.
- x represents the number of hours.
- 555x represents the number of pages he reads in x hours (555 pages per hour).
- 555 * 444 represents the total number of pages he read in 444 hours.
