A line that is perpendicular to 3y=11-8x has slope m=
Step-by-step explanation:
for a perpendicular,
make x the subject.
8x=11-3y
x=11/8 +3/8
for a perpendicular, the gradient
x= -1/m
x= (-1/11/8) - (-1/3y/8)
x= 8/3y -8/11.
therefore the gradient (m) = 8/3y -8/11.
if f(x) = 6x - 4, which is f(x) when x=8 ?
A scale drawing of a living room is shown below 5.5 inches and 3 inches scale 1:30 what is the area of the actual living room? Round your answer to the nearest whole number
Answer:
14850 inches
Step-by-step explanation:
The complete question is...
A scale drawing of a living room is shown below:
A rectangle is shown. The length of the rectangle is labeled 5.5 inches. The width of the rectangle is labeled 3 inches. The scale is 1 to 30.
What is the area of the actual living room in square feet? Round your answer to the nearest whole number.
The ratio of the scale = 1:30
This means that the dimensions of the drawing has been reduced to 1/30 of the actual building's dimensions.
We first scale up the drawing to 30 times to get the dimensions of the actual building.
The length on the drawing = 5.5 inches
The real length of the actual building = 5.5 x 30 = 165 inches
The width of the drawing = 3 inches
The width of the actual building = 3 x 30 = 90 inches
The area of the actual building = length x width
==> 165 x 90 = 14850 inches

Stickers come in packs of 5. Max buys 12 packs. He gave his three friends some stickers. They each receive the same number. He has 27 stickers left. How many stickers did max give each of his friends?
Answer: 11 stickers each
Step-by-step explanation:
given data:
packs of stickers bought by mark = 12 ( 5 ) = 60 stickers
no of stickers left with mark = 27
= Total no of stickers – stickers remaining with mark
= 60 – 27
= 33 stickers
he gave his 3 friends equal number of stickers.
3x = 33
x = 11
number of stickers received by each friend is 11

Answer:
105 cm squared
Step-by-step explanation:
15×6 to get the rectangle =90
then we have a triangle left so you do 15- 9 for the base =6 and multiply that by hight (6×5=30) and since it's a triangle and not a square we have to divide that answer by 2 and we get 15. Add those together, we get 105. Hope that helped!
The area of the shape below is 105 cm².
What is the area of a Rectangle?The area of a rectangle is calculated by multiplying the length and width of the rectangle.
What is the area of a Triangle?
The area of a triangle is equal to half of the product of the triangle's base and height.
How to solve the problem?Cut the shape given into a triangle and a rectangle as given in the following figure. Then the area of the shape is the sum of the area of the triangle and the area of the rectangle. In the shape, we can clearly specify that the base of the triangle is (15-9) cm=6cm and the height is
(11-6)cm=5cm.
Thus,
The area of the rectangle in the figure is (6×15) cm²=90 cm², and
the area of the triangle in the figure is (1/2)(6×5) cm²=15 cm².
Hence, the area of the shape is 90+15 cm² = 105 cm².

The change in the amount of money that Noah's mother
has can be represented by the
expression Choose... The expression can be simplified to Choose... which
shows that Noah still owes Choose... to his mother.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Amount Noah borrowed from his mother = $17
Amount paid = $8
Change in the amount of money Noah's mother has :
Let initial amount her mother has = x
Hence, the amount she has after Noah paid $8 to her will be :
Initial amount - amount borrowed + amount paid
= x - $17 + $8.
The simplified amount = x - $9
The amount Noah still owes :
Total amount owed - amount paid
$17 - $8 = $9
The change in the amount of money that Noah's mother will be $ 9.
What is Algebra?Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.
Noah borrowed $17 from his mother. He then paid back $8 of the amount he owed.
Then the amount owed will be given as the difference between the initial amount and paid amount.

Malcom has $638.54 in his checking account he must maintain a $500 balance to avoid a fee he wrote a check for $159.50 today write and solve an inequality to solve for the least amount of money he needs to avoid a fee
Answer:
$20.96
Step-by-step explanation:
He has $638.54 in his account and writes a check for $159.50. The amount of money he needs to stay at or above $500 is denoted by x.
638.54 - 159.50 + x >= 500
After writing a check, Malcom has $479.04 left in his account, which is below his cutoff.
479.04 + x >= 500
He must add at least x amount of dollars to his account to avoid a fee.
x >= 20.96
In order to avoid a fee, Malcom must add a minimum of $20.96 to his account.

Step-by-step explanation:
In a similar rectangle , the ratio of lengths should be equal to ratio of widths.
Ratio of lengths =

Answer:
x = -7/9
Step-by-step explanation:
The usual recommendation is to clear fractions first. Here, you can do that by multiplying both sides of the equation by 6.
6(-1/2(3x -4) +3x) = 6(5/6)
-9x +12 +18x = 5 . . . . . . . . . simplify
9x = -7 . . . . . . . . . . . . . . . . . subtract 12
x = -7/9 . . . . . .divide by 9

Another way to do this is to eliminate parentheses first.

5 (t+3)=-3.5 solve for t
Answer:
t=-3.7
Step-by-step explanation:
5 (t+3)=-3.5
solving the bracket we have;
5t+15=-3.5
collect like terms
5t=-3.5-15
5t=-18.5
divide both sides by 5;
t=-3.7
The value of t in the given algebraic expression is; t = -2.3
We are given the equation;
5(t + 3) = 3.5
Using distributive property on the left hand side, we have;
5t + (5 × 3) = 3.5
5t + 15 = 3.5
Using subtractive property of equality, subtract 15 from both sides to get;
5t + 15 - 15 = 3.5 - 15
5t = -11.5
Divide both sides by 5 to get;
5t/5 = -11.5/5
t = -2.3

Nolan is driving to a concert and needs to pay for parking. There is an automatic fee of $8 just to enter the parking lot and when he leaves the lot he will have to pay an additional $3 for every hour he had his car in the lot. How much total money would Nolan have to pay for parking if he left his car in the lot for 6 hours? How much would Nolan have to pay if he left his car in the lot for t hours?
Answer:
i. $26
ii. $(8 + 3t)
Step-by-step explanation:
Given that: automatic fee is $8, and fee per hour is $3. Then;
i. If he left his car in the lot for 6 hours, amount to be paid can be calculated as thus;
since fee per hour is $3, then for 6 hours; the fee = 6 x $3
= $18
Total amount to be paid after 6 hours = automatic fee + $18
= $8 + $18
= $26
For parking his car for 6 hours, he would pay $26
ii. Amount paid for t hours = automatic fee + $ 3 x t
= $(8 + 3t)
Tavon has a gift card for $130 that loses $3 for each 30-day period it is not used. He has another gift card for $110 that loses $2.50 for each 30-day period it is not used. a. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal. b. What will the value of each card be when they have equal value? a. If x is the number of 30-day periods, then the equation can be used to find the number of 30-day periods until the values of the gift cards will be equal.
(Type an equation. Use integers or decimals for any numbers in the equation.)
Answer:
55
Step-by-step explanation:
The required solution is 40 and after 40days $10 left for each of the gift card.
It is required to find the solution.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. Equation, statement of equality between two expressions consisting of variables and/or numbers.
Given:
The first equation is 130 - 3x because you start with $130 and subtract 3 for each 30 day period.
The second equation is 110-2.50x
Set them equal to each other: 130 - 3x = 110 - 2.50x
Solve for x:
130 - 3x = 110 - 2.50x
130-110=3x-2.50x
20=0.50x
40 = x
After 30-40 day periods (1200 days), both cards should have equal value.
Card 1 after 40 periods,
=130 - 3(40) = $10 left
Card 2 after 40 periods
=110 - 2.5(40) = $10 left
Therefore, the required solution is 40 and after 40days $10 left for each of the gift card.
