How to solve this maths problem?
Pls help
Answer:
Step-by-step explanation:
(a) The length and breadth of the playground as measured by the surveyor are 20 m and 13 m respectively to nearest metre.
Since the actual length is x m and breadth is y m, then;
i. x ≥ 20 m or x ≤ 20 m
ii. y ≥ 13 m or y ≤ 13 m
(b) perimeter of the playground = 2 (length + breadth)
= 2 ( 20 + 13)
= 2 x 33
= 66 m
The range of values of the perimeter = 65.4 m < perimeter < 66.5 m
ii. area of the playground = length x breadth
= 20 x 13
= 260 [tex]m^{2}[/tex]
The range of values of the area = 259.4 [tex]m^{2}[/tex] < Area < 260.5 [tex]m^{2}[/tex]
simplify the answer as much as possible
Answer:
f(-5)=240
g(-7)=-33
Step-by-step explanation:
1) f(x)=3x^2 - 3x
f(-5)= 3×(-5)^2 - 3×(-5) = -15^2 + 15= 225 + 15=240
2) g(x)=5x + 2
g(-7)= 5×(-7) + 2= -35+2=-33

On a snowy winters eve two candles are lit at the exact same time. A 18-inch candle and a 21-inch candle are lit at the exact same time. The 18-inch candle burns 2 inches every hour. The 21-inch candle burns 3 inches every hour. Create a system of equations using the information
Answer:
y=21-3x and y=18-2x
Step-by-step explanation:
Ok, so we have candle A, which is 21 inches and burns 3 inches every hour. in slope-intercept form, the hours would be the x, the 21 is our y intercept. So the first equatio would be y=-3x+21 (negative slope, because the height of the candle is going down). Candle b, which is 18 inches, burns away 2 inches each hour. We can make -2 the slope (negative 2, since the candle is being burned away, not being added to), and the 18 our y intercept. So the two equations would be
y=21-3x
and
y=18-2x
hope this helps!
Find the curcumince of the circle. use 3.14 or 22/7.
Answer:
the circumference of this circle is approximately 25.12 cm with π as 3.14.
Step-by-step explanation:
circumference of a circle is technically a perimeter of a circle.
we find the circumference of a circle by using the following formula :
c = 2πr or c = πd
r represents the radius d represents the diameter
since 4 yds here is a radius, we use the left formula i placed above. then, we substitute the numbers in. pi represents 3.14 as said in your question. even if you use 22/7, you will still get around the same result.
c = 2πr
c = 2(3.14)4
c = 6.28(4)
c = 25.12 yds
therefore, the circumference of this circle is approximately 25.12 yds.

Answer:
Step-by-step explanation:
4 year Public University
Tuition and fees $ 8500
Room and board $ 6700
Books and supplies $1250
misc expenses $ 700
Total for 1 year
8500+6700+1250+700
= $ 17150
Total for 4 years 4* 17150 = $68600
4 year Private University
Tuition and fees $ 25100
Room and board $ 8000
Books and supplies $ 1300
misc expenses $ 750
Total for 1 year
25100+8000+1300+750
= $ 35150
Total for 4 years 4* 35150 = $ 140600
2 Year Community College
2 Year Community College
Tuition and fees $ 4400
Room and board $ 5000
Books and supplies $ 1100
misc expenses $ 800
Total for 1 year
4400+5000+1100+800
= $ 11300
Total for 2 years 2* 11300 = $ 22600
now given
kari will get $4500 in scholarships and grants yearly and $1500 yearly through work study program
so in total kari will get in financial aid = $6000 yearly
so in 2 years she will get total = 2*6000 = $12000 financial aid
kari's estimated cost per year = total fee of college for 1 year - total financial aid for 1 year
= $11300 - $ 6000 = $5300
Kari's estimated cost per year = $5300
then estimated cost for two years = 2* 5300 = $10600
given Kari's family will contribute $3000 yearly
so for two years Kari will get = 2*3000 = $6000 from family
If kari has 1 year to save for 1st year's contribution then
a) kari has $0 in savings
kari needs to save for year = estimated cos per year - contribution from family per year
= $5300 - $ 3000 = $2300
as kari has $0 savings so kari needs to save $2300 in 1 year
so kari needs to save an amount = 2300/12 = $191.666667 monthly
b) kari has $1000 in saving
then kari needs to save an amount for 1 year = estimated cost per year - contribution from family per year - kari's initial savings
Amount to be saved for 1 year = $5300 - $3000 - $1000
= $1300
so kari needs to save an amount of = 1300/12 = $108.3333333 monthly
c) Kari has $2000 in saving
then kari needs to save an amount for 1 year = estimated cost per year - contribution from family per year - kari's initial savings
Amount to be saved for 1 year = $5300 - $3000 - $2000
= $300
so kari needs to save an amount of = 300/12 = $25 monthly

Estimation on a scale drawing of a fence, 3.75 inches represent 24 feet . what. is the actual length of a second fence is 2.8 inches in the drawing?
The exact length of the second fence is __ feet.
Answer: 17.92 feet
Step-by-step explanation:
From the question, we are informed that the estimation on a scale drawing of a fence is that 3.75 inches = 24 feet.
Based on the above, 1 inch will be:
= 24/3.75
= 6.4 feet
Therefore, the actual length of a second fence that is 2.8 inches in the drawing will be:
= 6.4 × 2.8
= 17.92 feet

A piece of rural land sold ten years ago for 40000. The price for the same land this year is $800 more per acre, and it sold for 60000. What is the size of the piece of land in acres?
Answer: 25
Step-by-step explanation:
From the question, we are informed that the piece of rural land sold ten years ago for 40000 and that the price for the same land this year is $800 more per acre, and it sold for 60000.
The size of the piece of land in acres will then be:
40000 + 800x = 60000
800x = 60000 - 40000
800x = 20000
x = 20000/800
x = 25
The land is 25 acres
Answer: 25
Step-by-step explanation:
40000 + 800x = 60000800x = 60000 - 40000800x = 20000x = 20000/800x = 25
