This diagram of a rectangular city park was drawn using a scale of 1 centimeter to 20 meters
(In the diagram shown, assume each square on the grid is 1 centimeter in length.)
What is the area, in square meters, of the actual park?
What is the scale factor?
Answers
Answer:
Scale factor for the drawing from actual park = [tex]\frac{1}{20}[/tex]
Area of the actual park = 1200 cm²
Step-by-step explanation:
Length of the rectangular city park = 5 cm
Width of the rectangular park = 6 cm
Using scale factor 1 cm = 20 meters
Scale factor = [tex]\frac{\text{length of the park in drawing}}{\text{Actual length of park}}=\frac{1}{20}[/tex]
[tex]\frac{5}{\text{Actual length of park}}=\frac{1}{20}[/tex]
Actual length = 5 × 20 = 100 meters
Actual width = 6 × 20 = 120 meters
Area of the rectangular park = length × width
= 100 × 120
= 1200 square meters
Therefore, Scale factor from actual length to the length in drawing = 1 : 20
Area of the rectangular park = 1200 square feet

If an object is projected upward with an initial velocity of 48 ft per second from a height h of 64 ft, then its height t seconds after it is projected is defined by the equation f(t) = -16(t) with superscript (2) + 48t + 64. How many seconds after it is projected will it hit the ground?
Answers
Answer:
4 seconds
Step-by-step explanation:
Given that :
Height of a projected object is modeled by:
f(t) = - 16t² + 48t + 64
t = height
How many seconds after projection will it hit the ground ;
When the projectile hits the ground ; t = 0
f(t) = - 16t² + 48t + 64
f(t) = 0
- 16t² + 48t + 64 = 0
Divide through by - 16
t² - 3t - 4 = 0
t² - 4t + t - 4 =0
t(t - 4) +1(t - 4) = 0
(t +1) = 0 or (t - 4) = 0
t = - 1 or t = 4
t can't be negative ;
Hence, the projectile will hit the ground after 4 seconds

Volunteers at Sams school use some of the student councils savings for a special project.They buy 4 backpacks for $9 each and fill each backpack with paper and pens that cost $5.By how much did the student councils savings change because of this project?
Answers
Answer: The student councils savings change by $41.
Step-by-step explanation:
Number of backpacks = 4
Cost of each backpack = $9
Paper and pen costs = $5
Total spending = (Number of backpacks ) x (Cost of each backpack ) + (Cost of paper and pen)
= $ (4 x 9 +5)
= $ 41
Hence, the student councils savings change by $41.

Prove that:
[tex] \tan(165) = \sqrt{3} - 2[/tex]
Please solve this question.
Answers
Answer: see attachment
Step-by-step explanation:
Given: cos 330 = √3/2
Prove that tan (165) = √3 - 2
Step-by-step explanation:
cos330° = cos(360° - 30°) = cos(2π - 30°)
Using, cos(2π - x) = cosx, x < 90°
=> cos(2π - 30°)
=> cos(30°)
=> √3/2 , proved
(ii): tan(165°) = tan(180° - 15°) = tan(π - 15°)
Using, tan(π - x) = - tanx
=> tan(π - 15°)
=> - tan15°
=> - (-√3 + 2)
=> √3 - 2 proved
For tan15° :
Using, tan2x = 2tanx/(1 - tan²x)
tan30° = 2tan15°/(1 - tan²15°)
1/√3 = 2tan15° / (1 - tan²15°)
1 - a² = 2√3 a {a = tan15°}
Solving this we get, a = -√3±2
As a = tan15°, it can't be -ve, thus
a = tan15° = -√3 + 2

The real answer is 8/11
Step-by-step explanation:
The fractional value of 0.72 is 18/25.
What is Decimal?A decimal is a number with a whole and a fractional part. Decimal numbers are between integers and represent numerical value for whole plus some fraction of a whole.
A decimal number comprises two parts: a whole number component and a fractional component. The decimal place value system is the same as the whole number value system for the whole component of a decimal number.
Given:
We have the decimal number 0.72.
Now, we can remove the decimal and put the number of zeroes in the denominator.
So, 0.72
= 72/100
Now, simplifying the fraction as
= 36/ 50
= 18/25
Now put decimal point ahead of two number from the numerator.
So, 37/100 = 0.37
So, the decimal is 0.37.

Step-by-step explanation:
3x+2y=34 x is the first number, y is the second.
1/2x+2y=34 multiply each number by two to get rid of the integer by the variable x.
x+4y=68 solve for x.
x=68-4y add this into the first equation to solve for variable y.
3(68-4y)+2y=34 solve for y.
204-10y=34
-10y= -170
y=17
