The blueprint's scale is
1 inch : 9 feet. If the gym's
area is 52 square inches on the
blueprint, what is the actual
square footage of the gym?
The area of the actual gym
is_square feet.
Answers
Answer:
4212 square feet.
Step-by-step explanation:
If the blueprint's scale is 1 inch : 9 feet.
Square both sides
(1in)² = (9ft)²
1in² = 81ft²
Given the gym's area as 52 square inches, hence;
52in² = x
Divide both expressions
1/52 = 81/x
x = 52 * 81
x = 4212ft²
Hence the area of the actual gym is 4212 square feet.

Step-by-step explanation:
According to the scenario, computation of the given data are s follows,
Cost of book = $x
Game cost = 3 × $x = $3x
So, we can calculate the total money spend by using following formula,
Total money spend = Cost of book + Game cost
By putting the value, we get
Total money spend = $x + $3x
= $4x
So, the total amount Danny spend is $4x.

Answers
Answer:
[tex] \displaystyle 53.6ft[/tex]
Step-by-step explanation:
refer the attachment
let the height be h
since we are given the adjacent side and want to figure out opposite side we'll use tan function
so our equation is
[tex] \displaystyle \tan( {15}^{ \circ} ) = \frac{h}{200} [/tex]
cross multiplication:
[tex] \displaystyle h = 200\tan( {15}^{ \circ} ) [/tex]
by using calculator we acquire:
[tex] \displaystyle h \approx 53.6ft[/tex]
hence,
about 53.6ft high in the tree ate monkeys
The figure above shows a store’s supply-demand graph for coffee makers. If the store sells $375 worth of coffee makers, which of the following is a valid possible price for them? a. $15 b. $25 c. $40 d. $55
Answers
b. $25
step-by-step explanation:
$375 / 15
25 coffee makers
$375 / 25
15 coffee makers
$375 / 40
9.375 coffee makers which makes no sense
$375 / 55
6.81818182 coffee makers which also makes no sense
coffee makers are usually over $20 so b makes the most sense here
The price of $25 is a valid possible price for coffee makers
What is a supply demand graph?A supply demand graph is a graph that shows the relationship between the supply and the demand of an item
The worth of the coffee is given as:
Worth = $375
The valid price of the coffee is calculated using:
Price = Worth/n
Where n represents the number of unit coffee
Make n the subject.
So, we have:
n = Worth/Price
This gives
n = 375/Price
When Price = 15, we have:
n = 375/15 = 25
When Price = 25, we have:
n = 375/25 = 15
When Price = 40, we have:
n = 375/40 = 9.375
When Price = 55, we have:
n = 375/55 = 6.818
Ignore the decimal results
So, we have
n = 375/15 = 25
n = 375/25 = 15
At a price of $25, the coffee maker sells less coffee than at a price of $15.
This means that they sell less to earn more
Hence, the price of $25 is a valid possible price for them

the first one. slope is 1/2 and y intercebt (b value) is positive 2.
Step-by-step explanation:
Answer:
y=1/2x+2
Step-by-step explanation:
This equation is linear because the graph is a straight line. Therefore, use the slope-intercept form y=mx+b to create the equation.
To find m (the slope), pick two points like (0,2) and (2,3). Find the change in y over the change in x: (y2-y1)/(x2-x1).
y2=3, y1=2, x2=2, x1=0
(3-2)/(2-0)= 1/2
This is the slope which means the equation is one of the first 2 options.
Next find b (the y-intercept) by finding the y value on the graph when x=0. When x=0, y=2. Therefore, b=2 and the final equation is y=1/2x+2

Answers
Answer:
There are 36 cards
Step-by-step explanation:
let blue be B and red be R
B:R =5:7
B/R = 5/7
there are 15 blue cards...
15/R = 5/7
make R subject of the formula...
R = (15×7)/5
R = 21
there are 21 red cards and 15 blue cards
Total number of cards = red cards + blue cards
= 21 + 15
= 36 cards
