Answer:
.82
41/50
Step-by-step explanation:
82%
Move the decimal 2 places to the left to change to decimal form
.82
Percent means out of 100
82/100
Divide by 2
41/50
Answer:
a) .82, b) 41/50
Step-by-step explanation:
a) The decimal form would be 0.82 - when writing a percentage as a decimal, we use 0.0-1.0 to represent 0% through 100%. Since it is 82%, it would translate to .82!
b) Since it is 82% out of 100%, we would write the fraction as 82/100. Additionally, you can divide it by 2 to get 41/50, thus reaching its simplest form!

Which are correct representations of the inequality -3(2x - 5) <5(2 - x)? Select two options.
Answer:
The third and fourth options.
Step-by-step explanation:
You simplify the inequality first...
-6x + 15 < 10 - 5x
-x < -5
x > 5
The first option is incorrect since it is less than.
The second option is basically -5x < 15; x > -3; that's incorrect.
The third option is basically -x < -5; x > 5; that is correct!
The fourth option is correct since it shows more than 5.
The fifth option is incorrect because it shows less than -5.

hi:) I need help with part 9(ii) ? Thanks :)!
Answer:
see explanation
Step-by-step explanation:
Given
2BD = 7BT , then
2(d - b ) = 7(t - b) ← distribute both sides
2d - 2b = 7t - 7b ( add 7b to both sides )
2d + 5b = 7t, thus
2[tex]\left[\begin{array}{ccc}10.5\\10\\\end{array}\right][/tex] + 5[tex]\left[\begin{array}{ccc}0\\3\\\end{array}\right][/tex] = 7t
[tex]\left[\begin{array}{ccc}21\\20\\\end{array}\right][/tex] + [tex]\left[\begin{array}{ccc}0\\15\\\end{array}\right][/tex] = 7t
[tex]\left[\begin{array}{ccc}21\\35\\\end{array}\right][/tex] = 7t , thus
t = [tex]\frac{1}{7}[/tex][tex]\left[\begin{array}{ccc}21\\35\\\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}3\\5\\\end{array}\right][/tex]
Hence T = (3, 5 )
Answer:
Please see the attached pictures for the full solution.
We reject x= -3 since x has to be between x=0 and x=10.5 since T lies on line BD.
We reject y= 1 since the y value has to be between 3 and 10 for T to lie on line BD.
Useful formula:
gradient=(y1-y2)/(x1-x2)
Further explanation:
1st picture, from line 12 to 13: cross multiply
line 14: expand
line 15: bring 9 over (or +9 on both sides)
line 16: ÷3 throughout
last picture: we have to show '(reject)' because whenever we introduce a square root, there must be a '±' sign.
linear inequality: solve -4x+2
Answer:
x≤-6
Step-by-step explanation:
-4x+2≥ 26
Subtract 2 from each side
-4x+2-2 ≥ 26 -2
-4x ≥ 24
Divide by -4 remembering to flip the inequality
-4x/-4 ≤-24/-4
x≤-6
Answer:
B. x ≤ -6
Step-by-step explanation:
-4x + 2 ≥ 26
Subtract 2 on both sides.
-4x ≥ 26 - 2
-4x ≥ 24
Divide -4 on both sides.
x ≤ 24/-4
x ≤ -6
Joshua is going to mow lawns during his summer break. The graph in the figure shows a linear relationship between the number of weeks he will be
mowing and the number of lawns he will mow. If he earns $25 for each lawn he mows, how much money will he earn after mowing lawns 5 weeks?
A. $125
B. $750
C. $1,500
D. $3,000
Answer:
$1,500
Step-by-step explanation:
We see on the graph that he mows 60 lawns in 5 weeks so if we multiply 60 by 25 because 25 is the amount of money he makes for each lawn he mows, we get 1,500 dollars.

Calculate the length of the unknown side of this right-angled triangle.
9 cm
17 cm
Answer:
14.4 cm
Step-by-step explanation:
Answer:
4√13
Step-by-step explanation:
Let's call the missing side length x
The given is a right triangle and in right triangle the square
length of hypotenuse is equal to square sum of other two side lengths
17^2 = 9^2 + x^2
289 = 81 + x^2 subtract 81 from both sides
208 = x^2
4√13 = x

Answer:
-47 > 1 - 8x > -63
-48 > -8x > -64 (subtract 1 from -47 and -63)
6 < x < 8 (divide inequality by -8; when you multiply/divide by a negative number you need to flip the sign)
Answer:
its wrong because when u moved the 8 to other side it would be positive. And u didnt switch sign for the 6
Step-by-step explanation:
-47 > 1-8x > -63
Seperate them into two inequalities
-47> 1-8x
Move 1 to the other side it will become -1
-47-1>-8x
-48>-8x
Divide -8 on both sides which will make the sign opposite because dividing with a negative number
6<x
1-8x>-63
Subtract 1 on both sides
-8x>-64
Divide -8 on both sides which will switch sign
x<8
Solve for x in the diagram.
Answer:
x = 15
Step-by-step explanation:
Using Pythagorean Theorem
=> [tex]c^2 = a^2+b^2[/tex]
Where c= x, a = 12, b = 9
=> [tex]x^2 = (12)^2+(9)^2[/tex]
=> [tex]x^2 = 144+81[/tex]
=> [tex]x^2 = 225[/tex]
Taking sqrt on both sides
=> x = 15

and distance of the last ramp is ______ feet (round to the nearest foot)
Answer:
The distance of the last ramp is 10 feet.
Step-by-step explanation:
From the options and the question, I assume that the height of the ramp is 6 feet. Pythagorean theorem states:
a² + b² = c²
where c is the hypotenuse, and a and b are the legs of the triangle. In this case:
6² + 8² = x²
√100 = x
10 ft = x

Answer:
10 crows and 5 ground hogs

Write an equation of the line passing through the point (7,3) that is parallel to the line 4x-7y=9
Answer:
y = -7/4x + 61/4
Step-by-step explanation:
Step 1: Write equation in slope-intercept form
-7y = 9 - 4x
y = 4/7x - 9/7
Step 2: Find slope of perpendicular line
Take the negative reciprocal of the 1st equation
m = -7/4
Step 3: Write out known variables
y = -7/4x + b
Step 4: Find b
3 = -7/4(7) + b
3 = -49/4 + b
b = 61/4
Step 4: Rewrite equation
y = -7/4x + 61/4
Does this table represent a function? why or why not?
Answer:
I think it's A but I could be wrong
Answer: B
Step-by-step explanation:
A graph or table is a function if it passes the vertical line test. That means, each x and only 1 y. One x cannot have more than 1 y because, that means it does not pass the veritcal line test. In the vertical line test, the vertival line only passes through 1 point, not 2. Since we know that this graph does not pass the vertical in test, we can eliminate C and D. We can eliminate A because 2 y-values can be the same as lone as there have different x. B fits the description of what we see on the table. Therefore, the answer is B.
Given the following function find f(-2)
Answer:
f(-2) = 1
Step-by-step explanation:
Simply plug in -2 for x in our given function:
f(-2) = (-2 - 3)/(2(-2) - 1)
f(-2) = -5/(-4 - 1)
f(-2) = -5/(-5)
f(-2) = 1
Answer:
1
Step-by-step explanation:
Plug x as -2 and solve.
(-2 - 3)/(2(-2) - 1)
-5/(-4 - 1)
-5/-5

For two months, Milan used the same landscaping maintenance company. The company had a fixed reservation rate per month, plus an hourly rate for the amount of time that is spent on landscaping work. Milan received two bills from the landscaping company. The first bill was $120.75 for 2.75 hours of
landscaping work and the second bill was $160.50 for 5.25 hours of landscaping work. Find the equation of the line that represents the landscaping company's fixed reservation rate and charge per hour. Round to the nearest cent, if necessary.
Answer:
The equation of the line that represents the landscaping company's fixed reservation rate and charge per hour is y=15.9x+77.025
Step-by-step explanation:
The first bill amount for 2.75 hours of landscaping work = $120.75
The second bill amount for 5.25 hours of landscaping work = $160.50
No we are supposed to find the equation of the line that represents the landscaping company's fixed reservation rate and charge per hour
So, we will us two point slope form to find the equation:
Formula : [tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex](x_1,y_1)=(2.75,120.75)\\(x_2,y_2)=(5.25,160.50)[/tex]
Substitute the values in the formula
[tex]y-120.75=\frac{160.50-120.75}{5.25-2.75}(x-2.75)\\y=15.9x+77.025[/tex]
Hence the equation of the line that represents the landscaping company's fixed reservation rate and charge per hour is y=15.9x+77.025

59. A car dealership has SUVs and sedans in a ratio of
5:9. How many sedans does the car dealership
have if there are 140 SUVs?
Answer:
The car dealership has 252 sedans.
Step-by-step explanation:
Number of SUVs = 140
Ratio of SUVs to sedans = 5:9
Sum of ratios = 5+9 = 14
Total number of cars = 14/5 × 140 = 392
Number of sedans = 9/14 × 392 = 252
