Answer:
11/200
Step-by-step explanation:
5.5% = 5.5/100 = 0.055
0.055 1000
———- X ———
1 1000
=55/1000
=11/200
Answer: b) the tiles are not similar because both SP:SR is 5:4 and MJ:ML is 5:2
<u>Step-by-step explanation:</u>
We are given that the tiles are rectangular which implies that they both have a 90° angle.
In order to prove similarity, We need to show that the lengths and widths are proportional.
P Q R S
J K L M
a) PQ : QR JK : LM
w=4 L=5 w=2 w=2
↓
We need Length (not width)
b) SP : SR MJ : ML
L=5 w=4 L=5 w=2
5 : 4 5 : 2
When comparing length to width they do not have the same ratio so the rectangles are not similar.
c) PQ : QR JK : KL
w=4 L=5 w=2 L=5
4 : 5 2 : 5
When comparing width to length they do not have the same ratio so the rectangles are not similar.
d) SR : ML PQ : JK
w=4 w=2 w=4 w=2
↓ ↓
We need Length (not width)
Answer: 2(x-7)
Step-by-step explanation: 2x−14
2x−14
=2(x−7)
Answer:
c=9.20p
Step-by-step explanation:
cost is what you're solving for so that goes on the outside. each package costs 9.20 so you multiply however many packages by that number when finding the cost.
Answer:
(e) all the students who think that foreign language classes should be required for everyone
Step-by-step explanation:
Given that the faculty senate at a large university wanted to know what proportion of the students thought foreign language classes should be required for everyone.
Just the statistics department helped to collect data from a sample of 500 students.
Because of this we cannot say all stats students is the population. Similarly 500 students form the sample and not population. the students who responded to the email survey are the real sample out of 500.
So correct answer for the population of interest is
(e) all the students who think that foreign language classes should be required for everyone
