Let us represent the number of tickets bought with t, the number of drinks bought with d, and the number of bags of popcorn bought with b. The expression for total cost becomes,
6.5t + 5.5d + 6b
We know that two tickets were bought, so we may plug in 2 for t and get the final expression:
6.5(2) + 5.5d + 6b
13 + 5.5d + 6b
Answer:
Prime
Step-by-step explanation:
If we have a point on a pre-image, we can have it labelled as A(x,y)
Now, we can write this as the image
To write this as the image, we simply have to add a mark on the A
This mark is at the upper right
We have it as A’ (x,y)
The part added is called a prime
Answer:
Step-by-step explanation:
The monthly rents paid by the 10 people are
845, 875, 890,900,960, 965, 990, 1015, 1045, 1065.
The mean rent is determined by
Sum of rent paid/ total number of people that paid rent.
Mean = (845+875+890+900+960+965+990+1015+1045+1065) /10 = 9550/10 = 955
Median = (960+965)/2 =1925/2 = 962.5
Suppose that one of the people moves, her rent changes from 1065 to 915, the mean becomes
(845+875+890+900+ 915 + 960+965+990+1015+1045)/10 =9400/10 = 940
The median is (915 +960)/2 =1875/2 = 937.5
Therefore,
a) the mean decreases by
955 - 940 = 15
b) the median decreases by
962.5 - 937.5= 25
Answer:
640 cm²
Step-by-step explanation:
Given 2 similar figures with ratio of sides = a : b, then
ratio of areas = a² : b²
Here the ratio of sides = 5 : 20 = 1 : 4, thus
ratio of areas = 1² : 4² = 1 : 16
The area of ABCD is 16 times the area of EFGH, so
area = 40 × 16 = 640 cm²
Answer: choice B
Step-by-step explanation:
