The image of the arrow is missing, so i have attached it.
Answer:
A_t = 69.5 cm²
Step-by-step explanation:
In a second image attached, I have divided the arrow into triangle and rectangle.
From the second image,
A1 is area of triangle while A2 is area of rectangle
Area of triangle is; A1 = ½bh
Our triangle base is given as 9 cm.
To get the height, we will subtract the rectangle height of 8 cm from the total arrow height.
Thus; height of triangle; h = 11 - 8 = 3cm
Thus;
A1 = ½ × 9 × 3
A1 = 13.5 cm²
Formula for area of rectangle is;
A2 = length × breadth
A2 = 8 × 7
A2 = 56 cm²
Thus, total area of arrow is;
A_t = A1 + A2 = 13.5 + 56
A_t = 69.5 cm²
Answer:
£1690
Step-by-step explanation:
Amount invested by Brian = £1300
rate of simple interest = 10%
To find money Brian will have after three years
He will have amount invested in bank and interest earned in three years from that amount.
Simple interest for any principal amount p is given by
SI = P*R * T /100
where SI is simple interest earned
T is time period for which simple interest is earned
R is rate of interest
Substituting value of P , R and T we have
SI = 1300*10* 3 /100 = 390
Therefor interest earned will be £390
Total money with Brian after three years = principal amount invested + interest earned in 3 years
= £1300 + £390 = £1690
Answer:
It will be 1:5
Step-by-step explanation:
If you divide 18 by 9 and 90 by 9 then you get 2 and 10. Then if you divide 2 by 2 and 10 by 2 you get 1 and 5. So, 18 is to 90 as 1 is to 5.
There are 10 seats in ferris wheel of love.
One couple can fit in to one seat. That means 1 couple per seat.
Given, in each minute a seat passes by the entrance or exit stage. That means one couple can use the seat for one minute. That means 1 seat per minute.
The wheel starts functioning at 8 p.m for half an hour. In 1 hour there are 60 minutes. So half an hour means 
= 30 minutes.
So we have got 1 couple per seat and 1 seat per minute. If we multiply them we will get 1 couple per minute.
We have got in 1 minute there is 1 couple.
So in 30 minutes there are 
couples = 30 couples.
We have got the required answer here.
There are 30 couples who took a ride in the ferris wheel of love.
