A magazine costs $3 and a book cost $7 if you want to spend exactly $45 on reading this month and you need to buy eight magazines how many books can you buy write an equation in standard form modeling the situation then see how many books you can buy let em represent the number of magazines you buy and B represents the number of books you buy.
Answers
Answer:
m = 8 and b = 3 OR m = 15 and b = 0
Step-by-step explanation:
Note that the conditions on this problem could be contradictory (they are likely not, but could be)
let m be the number of magazines bought
let b be the number of books, then
3m is the cost of the magazines bought and
7b is the cost of the books bought, since $45 exactly must be spent then
3m + 7b = 45
Let us assume m = 8 and see what happens
3(8)+7b = 45
24+7b=45
7b=21
b=3, this meets the requirements and results in an integer (whole) number of books, if b had ended up as a fraction, then m=8 would have to be wrong and we would have tried m=9 , then 10, 11, 12, up to 15 if necessary until we got a whole number of books. Notice that 15 magazines and 0 books also works
The area of a rectangular outdoor stage has been extended on one side. The entire new area in square meters can be written as 216+12x. Factor the expression to find the dimensions of the extended stage.
PLZ HELP
Answers
Answer:
Dimension of the extended stage is; length = 6 m and width = 2x m
Step-by-step explanation:
Area of the rectangular outdoor = length x width
New area = area of the outdoor + area of the extended stage
= 216 + 12x
= 6(36 + 2x)
New area = 6 (36 + 2x)
So that;
The dimension of the rectangular outdoor = 36 x 6
i.e length = 36 m and width = 6 m
So that the dimension of the extended stage = length x width
= (6 x 2x) m
i.e length = 6 m and width = 2x m
The radius of the Ferris wheel is 125ft. Which is the circumference of the Ferris wheel, rounded to the nearest foot?
Answers
Answer: 786 ft
Step-by-step explanation:
The Ferris wheel is circular in shape so this can be treated as a circle.
If the radius is 125 ft, the circumference can be calculated with the formula:
= 2 * π * radius
= 2 * 22/7 * 125
= 785.71 ft
= 786 ft

a map is drawn in the scale of 1:500000. the area of a pond on the actual ground is 100km^2. find the area on the map in square centimetres that represents the pond
Answers
Answer:
2 000 000 [tex]cm^{2}[/tex]
Step-by-step explanation:
100 [tex]km^{2}[/tex] = 1 000 000 000 000 [tex]cm^{2}[/tex]
the scale of 1:500000 means that 1 cm in the map represents 500000 cm in reality
So on the map this pond's area would be
[tex]\frac{1 000 000 000 000}{500000}[/tex] = 2 000 000 [tex]cm^{2}[/tex]

x=11 please correct me if i'm wrong. I hope I helped.
Step-by-step explanation:
2x-5=8
add 2 to both sides
so the 2 on the left cancels out, and now on the right it is 6
now add 5 to both sides, so x is by its self and on the right of the equation sign it is 11
so x=11

Joquan's brother earns a 2.5% commission on the amount he sells.
Last week, he sold $9,900 worth of shoes, thus his commission will be calculated as follows:
2.5% of $9,900 = 2.5 *$9,900 / 100 = $247.50
His commission was $247.50

Try to find the area of the brown spots, which filled in as green, would make one big rectangle.
1. Take the whole area of the rectangle (use the area of the brown rectangle around the green, and the area of the brown triangle towards the top left).
The area for the brown rectangle
A = b*h becomes A = 2*3 = 6 ft^2
Area for brown triangle (upper-left) is found by the length of the whole figure shown. The whole length is 12ft at the bottom; at the top, we know 6ft and 2ft. Therefore, the missing measurement there is 12ft - (6ft + 2ft) = 4ft
Area for the triangle (I will include some trigonometry; don’t be afraid to use it!:)
Find the long side of the triangle:
Pythagorean Theorem: a^2 + b^2 = c^2
which becomes:
3^2 + 4^2 = c^2
9 + 16 = c^2
c^2 = 25
sqrt(c^2) = sqrt(25)
c = 5
Next,
I know there are easier formulas and processes for the following, but they will work.
S (semiperimeter)= 1/2(a+b+c)
Counting up the sides of the triangle, then dividing by two will give you your semiperimeter.
Then,
A= sqrt [(S)(S-a)(S-b)(S-c)] = 6
I believe that the S value and a value are the same because that brown triangle made earlier is a 3-4-5 triangle (the sides).
Finally, now that we know the area of the brown rectangle and the brown triangle, we can subtract them from the big rectangle!
1. The big rectangle: A= b*h becomes A = 12*5 = 60 ft^2
2. Take the 60 ft^2 and set up the following:
60 ft^2 - (6ft^2+6ft^2) = 60ft^2 - 12ft^2 = 48ft^2, as the final answer.

Rectangle HYGT has a perimeter of 170 inches. If the length is 10x - 7
and the width is 6x + 12, how wide is the rectangle?
Answers
Answer:
The wide of the rectangle = 42 inches
The length of the rectangle = 43 inches
Step-by-step explanation:
Step(i):-
Given that the length of the rectangle = 10x-7
Given that the width of the rectangle = 6x +12
The perimeter of the rectangle = 2(length + width)
Given that the perimeter of the rectangle = 170
Step(ii):-
2(length + width) = 170
length + width = 85
10x-7 +6x +12 =85
16x +5 = 85
16x = 85-5 = 80
x = [tex]\frac{80}{16}[/tex]
x = 5
Final answer:-
The length of the rectangle = 10(5)-7 = 50-7 = 43
The wide of the rectangle = 6x +12 = 6(5) + 12 = 30+12 =42
The perimeter is the sum of its all sides. The rectangle is 42 inches wide.
What is the perimeter of the rectangle?The perimeter is the sum of its all sides. The perimeter of the rectangle is twice the sum of its length and its width.
[tex]\rm \text{Perimeter of rectanle}=2(Length +Breadth)[/tex]
As it is given to us that the length of the rectangle is (10x-7), while the width of the rectangle is (6x+12). Also, the perimeter of the rectangle is 170 inches. Therefore, using the formula of the perimeter of the rectangle we will get,
[tex]\rm Perimeter=2(Length +Breadth)\\\\170=2[(10x-7)+(6x+12)]\\\\170=2{10x-7+6x+12}\\\\170=2(16x+5)\\\\170=32x+10\\\\32x=160\\\\x=\dfrac{160}{32} = 5[/tex]
Now, substitute the value of x,
The width of the rectangle = 6x + 12 = 6(5)+12 = 30+12 = 42 inches.
Thus, the width of the rectangle is 42 inches.

equation to find original price if sale price of $429 is a 34% discount
Answers
Answer:
The original price is $650
Step-by-step explanation:
There's an actual algebra method for this, but this is my method because I find it way easier to remember.
Since the most you can discount out of an item is 100% (well, it's considered free then) let's subtract 100 - 34, which is 66.
Now, turn it into a decimal because it makes the numbers easier- 0.66.
Since when you're finding the discount of an original price, you multiply the original price by the discount- instead for finding the original price for a discounted item we divide $429 by 0.66 instead, since when you divide a number by another number that's under 1 the quotient is a larger number.
So, 429 ÷ 0.66 = 650.
Therefore, the original price of the $429 sale price for a 34% discount is $650.
