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
a cone has a radius of 5 m and a height of 3 m.What is the volume of the cone?
Answer:
78.54 [tex]m^3[/tex]
Step-by-step explanation:
Use the formula for the volume of a cone of circular base with radius "R" and height "H", using the given values for the radius R (5 meters), and the cone's height (3 meters)
[tex]Volume= \pi R^2 \frac{H}{3} \\Volume = \pi 5^2 \frac{3}{3} m^3 = 78.539816.... m^3[/tex]
And we round the answer to two decimals:
Volume = 78.54 [tex]m^3[/tex]

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

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.

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.

What is the slope of (5,3) and (5,-9)
The slope is the change in Y over the change in X.
A point is written as ( X,Y), where the first number is the X and the second number is the Y.
You have:
(5,3) and (5,-9)
The change in Y is -9 - 3 = -12
The change in X is 5-5 = 0
The slope becomes -12/0
Because you have a 0 on the bottom of the fraction the slope is undefined because you cannot divide by 0.
The slope is undefined.

2x+9=35
Hey!
---------------------------
Solution:
2x + 9 = 35
2x + 9 - 9 = 35 - 9
2x = 26
2x/2 = 26/2
x = 13
---------------------------
Answer:
x = 13
---------------------------
Hope This Helped! Good Luck!
Answer:
x = 13

Given
2x + 9 = 35 ( isolate 2x by subtracting 9 from both sides )
2x = 26 ( divide both sides by 2 )
x = 13
Norma's credit card has an APR of 16%, calculated on the previous monthly
balance, and a minimum payment of 2%, starting the month after the first
purchase. Her credit card record for the last 7 months is shown in the table
below.
Norma's credit card balance at the end of the 7th month is $1,487.22.
How to solveCalculate the interest for each month.
Interest = (Previous month's balance * APR) / 12
Calculate the new balance for each month.
New balance = Previous month's balance + Purchases + Interest - Payments
Here's the calculation for each month:
Month 1:
Interest: 0 (No interest on the first month)
Balance: $500 + $0 = $500
Month 2:
Interest: ($500 * 0.16) / 12 = $6.67
Balance: $500 + $200 + $6.67 - $10 = $696.67
Month 3:
Interest: ($696.67 * 0.16) / 12 = $9.29
Balance: $696.67 + $300 + $9.29 - $20 = $986.29
Month 4:
Interest: ($986.29 * 0.16) / 12 = $13.15
Balance: $986.29 + $100 + $13.15 - $20 = $1079.44
Month 5:
Interest: ($1079.44 * 0.16) / 12 = $14.39
Balance: $1079.44 + $150 + $14.39 - $10 = $1233.83
Month 6:
Interest: ($1233.83 * 0.16) / 12 = $16.45
Balance: $1233.83 + $0 + $16.45 - $15 = $1235.28
Month 7:
Interest: ($1235.28 * 0.16) / 12 = $16.47
After all the computations, taking into consideration the amount spent and paid earlier,
Norma's credit card balance at the end of the 7th month has amounted to $1,487.22.

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

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
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.
