Step-by-step explanation:
All these questions can be solved remembering that the area of a triangle is the base*height/2
1) 9.8*3.6/2 = 17.64
2) 14*35/2 = 245
3) 8.4*6.9/2 = 28.98
4) For this one, it is important to realize that if a triangle contains 2 perpendicular lines, it is a right triangle, and therefore, those two lines must be the base and the height. So the answer is just 1.8*2.5/2 = 2.25
5)3.2*9.6/2 = 15.36
Answer:
first is 17.64cm second is 245m third is 28.98cm fourth is 15.36

write 7.16 x 10^-5 in standard notation
Answers
Answer:
So this is called scientific notation, you can write as
7.16e-5 not saying euler's number.
To put in standard you move the decimal point in the direction of the sign and that many times. So in this case the direction of the sign is - because -5 so we move the decimal to the left, in this case we do it 5 times. So we move it five times 0.000716 is what you get

hello
Thanh have 3,5 meters of fabric. i can say
3,5/1 for it.
and i can say 35/10
now he used three-fourths of a meter of fabric.
its equal to 3/4
now i have to remove 3/4 from 35/10.
35/10 - 3/4
denominators have to be same thats why im expanding them to 20.
35×2/10×2 = 70/20
3×5/4×5 = 15/20
now i can remove 15/20 from 70/20!
70/20 - 15/20 = 55/20
we cannot see 55/20 in the options.
thats why im dividing them with 5.
55÷5= 11 20÷5=4
the answer is 11/4
11/4 = 2and 3/4
so its option 2
good luck(:

Answer:
y = -x/2 -3
Step-by-step explanation:
So there are LOTS of ways you can choose to do this, but this is how i do it:
I like to move all the x to one side first, so:
2y = -x -6
Then we have to divide everything by 2 to get y on its own:
y = -x/2 -3
*you can divide first too if you want, i find that this keeps it nice and simple though

following expressions represents the total profit Heather will bring in?
Answers
Answer:
35t+25l +55d
Step-by-step explanation:
35t+25l +55d is the profit
t is the number of tops, l is the number of leggings and d is the number of dresses
Answer:
So A is there just to make you trick you, its not even related and doesn't have the numbers here. And same goes for D. So we have B and C left. C doesn't make any sense because you're multiplying everything by 105 and that is not even a number specified here. So that just leaves B and its also logical, you're multiplying it by the numbers specified. Therefore the answer is
B is answerA trader purchased 1,000 books at the rate of $5.40 per book and spent $200 towards transportation. If he wants to earn a profit of 12.5%, at what price should he sell each book? ( with explanation )
Answers
Answer:
$6,300
Step-by-step explanation:
Step 1
Find the Cost Price of the books
A trader purchased 1,000 books at the rate of $5.40 per book
This is calculated as:
If 1 book = $5.40
1000 books = ???
We cross multiply
1000 books × $5.40
= $5,400
He bought 1000 books for $5,400
His total cost price = Transportation + Cost of books
Transportation = $200
Cost price = $5,400 + $200
= $5,600
Step 2
Find the profit he made from the sale of the books
Percentage profit = Profit / Cost price × 100
Percentage profit = 12.5%
Cost price = $5,600
We have :
12.5 = Profit/ $5,600 × 100
12.5 = (100 × Profit)/ $5,600
Cross multiply
12.5 × $5,600 = 100 × Profit
Divide both sides by 100
(12.5 × $5,600) ÷ 100 = Profit
Profit = $700.
Step 3
Find the selling price
The Formula to calculate Selling Price is given as:
Selling price = Cost Price + Profit
Selling price = $5,600 + $700
Selling price = $6,300

A giant circular fair ride has a radius of 60m, with 12passenger pods spaced around the circumference at equal distances. How far is it directly from the sixth pod to the tenth pod?
Answers
Answer:
The distance between the 6th and 10th seat is approximately 126m
Step-by-step explanation:
First of all, we will need to calculate the circumference of the circular fair ride.
This is [tex]2\pi r= 2 \times \pi \times 60=377m[/tex]
hence the circumference of the circle is 377m
At this point, we will have to take note that the pods are equally spaced.
To get the distance between the sixth pod and the tenth pod, we will have to use the principle of fractions of a whole.
There are 12 seats in total, the distance between the 6th and tenth seat is 4 seats. Expressing this distance in terms of seats, as a fraction is 4/12 equally spaced seats.
This ratio can be related to the circumference of the circle as
[tex]\frac{4}{12} \times377=125.66m \approx 126m[/tex]
Therefore, the distance between the 6th and 10th seat is approximately 126m

If the mean of the data set is 84 points, find Haruka's final exam score in chemistry.
Final exam Score on a 100 -point scale
Astronomy 72
Biology 85

Chemistry ??
Answers
Answer:
Haruka's final exam score in chemistry is 87
Step-by-step explanation:
Given mean of data set = 84
given score
Astronomy 72
Biology 85
Physics 92
Chemistry ?
we have to find score of chemistry
let the score of chemistry be x
we know that mean is sum of data set divided by no of terms in data set
mean = sum of data set /no of terms in data set
number of terms in our problem is 4 (Astronomy,Biology,Physics,Chemistry)
sum of set
72+85+92+x = 249+ x
as mean is 84,
hence
84 = (249+ x)/4
=> 84*4 = 249 + x
=> 336 = 249 + x
=> 336 - 249 = x
=> x = 87
Thus, Haruka's final exam score in chemistry is 87.
