A football field measures 100m by 72m . A school marks a football field similar in shape to a full size football field but only 30m long . What is its width ?
Answers
Answer: 240 m
Step-by-step explanation:
Given
Football field measures [tex]100\ m\times 72\ m[/tex]
Another similar field of length
[tex]L=30\ m[/tex]
and width, say W is marked
So, their area must be the same
[tex]\Rightarrow 100\times 72=30\times W\\\\\Rightarrow W=\dfrac{7200}{30}=2540\ m[/tex]
The width of the football field is 41.7m
The football measures 100m by 72 m. The school football field is similar.
Similar rectanglesFor similar rectangles, the corresponding sides have common ratios. Therefore, let's establish the proportion as follows:
100 / w = 72 / 30cross multiply
3000 = 72w
divide both sides by 72
w = 3000 / 72
w = 41.6666666667
w = 41.7 m

It costs $32 per day to rent a medium-sized car, plus $0.25 for each mile driven over 150 miles. The equation that represents this situation is y = 0.25x + 32, where y represents the total cost of renting a car, and x represents the number of miles driven over 150 miles.
a.) What is the slope and what does it represent in the context of this problem?
b.) What is the y- intercept and what does it represent in the context of this problem?
Answers
Answer:
Read explanation
Step-by-step explanation:
A)The slope is the number before the X so 0.25, this represents the amount of money people have to pay for each mile driven over 150 miles.
B) The y-intercept is the number after the X so 32, this number represents the amount people have to pay rent the car before actually using it.

What is the probability of a face with less than 5 spots turning up when you toss a die?
answer correctly and please explain
Answers
Answer:
2/3
Step-by-step explanation:
Probability =
= No. of faces having less than 5 spots / Total no. of faces
= 4/6
=2/3
The probability of a face with less than 5 spots turning up when it tosses a die which has 6 total outcomes is 2/3 or 0.667.
What is probability of an event?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
The probability of a face with less than 5 spots turning up when a die is tossed has to be find out.
Here, in this die, it is known that,
The number of total outcome is 6 {1,2,3,4,5,6}The number of favorable outcome to be a face with less than 5 spots is 4 {1,2,3,4}.Thus, the probability of this event is,
[tex]P=\dfrac{4}{6}\\P=\dfrac{2}{3}\\P=0.667[/tex]
Thus, the probability of a face with less than 5 spots turning up when it tosses a die which has 6 total outcomes is 2/3 or 0.667.

A trapezoid , having a height of 14 cm , has an area
of 224 cm² . The big base measures 2 cm more than the
small base. What are the lengths of the two bases ?
it should be solved as a system
Answers
Answer:
17 cm and 15 cm.
Step-by-step explanation:
Area of a trapezoid = h/2(a + b) where h = height and a and b are the 2 bases.
so we have:
(14/2)(a + b) = 224 Distributing:
7a + 7b = 224 Dividing thru by 7:
a + b = 32
Also we have
a - b = 2 where a = longest base.
Adding the last 2 equations:
2a = 34
a = 17
So b = 17 - 2 = 15.

A teacher is planning a class trip to the aquarium. The aquarium requires 2 chaperones for every 15 students. The teacher plans accordingly and orders a total of 85 tickets. How many tickets are for chaperones, and how many are for students?
Answers
Answer:
75 student tickets and 10 chaperone tickets
Step-by-step explanation:
First find out how many groups there are total by dividing 85 by 1 group total of 17 (15 students 2 chaperones).
85 / 17 = 5
Since you now know there are five groups of 15 students and 2 chaperones all you have to do is multiply 5 time 15 students and 5 times 2 chaperones.
15 x 5 = 75 for students
5 x 2 = 10 for chaperones

Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
now apply the above rules to the given triangle
where we are given the angle of 30° and the Adj side of 27
y is the Hyp of this triangle and x is the Opp side of this triangle, now plug in the given values as follows
so use CAH Cos(30) = 27 / Hyp
Hyp = 27 / Cos(30)
Hyp = 27 / ([tex]\sqrt{3}[/tex] / 2)
Hyp = 27 * 2 / [tex]\sqrt{3}[/tex]
Hyp = 54 / [tex]\sqrt{3}[/tex]
y = 54 / [tex]\sqrt{3}[/tex]
use SOH, since we know the exact value for the Hyp from above
Sin(30) = Opp / ( 54 / [tex]\sqrt{3}[/tex] )
Sin(30) * 54 / [tex]\sqrt{3}[/tex] = Opp
1/2 * 54 / [tex]\sqrt{3}[/tex] = Opp
27 / [tex]\sqrt{3}[/tex] = Opp
x = 27 / [tex]\sqrt{3}[/tex]

There are 4 consecutive integers that have sum of 266 . Which integers are they?
Answers
Answer:
the four consecutive integers are 65 , 66 , 67 and 68 .
Step-by-step explanation:
you should let the first integer be x
so that would leave the 2nd as x + 1
The 3rd would be x + 2
and the 4rth would be x + 3
so X + X + 1 + X + 2 + X +3 =266
you can combine your like terms:
X+X+X+X= 4x
and 1+2+3=6
then you do simple algebra:
4x= 266-6
266-6= 260
4x=260
divide both sides by 4
260/4 is 65
x = 65
65 is your answer then you go up by 3 numbers.
