Answer:
0.4%
Step-by-step explanation:
Given that:
Number of people with mild allergic reaction = 28
Total number of people = 7000
To find:
Percentage of people who have a mild allergic reaction to the shampoo = ?
Solution:
First of all, let us understand how can we calculate percentage of a particular amount.
Percentage of a particular amount can be calculated by dividing the amount with the total amount and then multiplying it with 100.
Percentage of [tex]p[/tex] from [tex]q = \frac{p}q\times 100[/tex]
Here,
[tex]p = 28\\q =7000[/tex]
Therefore, the percentage of people who have mild allergic reaction:
[tex]\dfrac{28}{7000}\times 100\\\Rightarrow \dfrac{2800}{7000} \\\Rightarrow 0.4\%[/tex]

Which combination of measurements could form a triangle?
A - 5m, 12m, 18m
B - 12m, 32m, 45m
C - 16m, 55m, 72m
D - 18m, 22m, 36m
Answer:
D - 18mm, 22mm, 36mm
Step-by-step explanation:
The only way for a triangle to be made, the 2 smallest side lengths must be greater than the longest side length. So for A through C, the smallest sides diden't add up to the longest side, therefore D is the only correct answer.

Reese's car has a 12 gallon gas tank. Right now, his gas gauge reads 1/3 full. If he buys 3 gallons of gas, what will the new reading on the gas gauge be?
Answer:
The new reading on the gas gauge will be will be 7/12 full
Step-by-step explanation:
From the question
Reese's car has a 12 gallon gas tank. Right now, his gas gauge reads 1/3 full.
Hence, the quantity of gas in the tank is currently:
12 gallon × 1/3
= 4 gallons
If he buys 3 gallons of gas
Total amount of gas = 4 gallons + 3 gallons
= 7 gallons of gas
The new reading on the gas gauge will be:
4 gallons of gas = 1/3
7 gallons of gas = x
Cross Multiply
4 gallons × x = 7 gallons × 1/3
x = 7 gallons × 1/3/4
x = 7/3 ÷ 4
x = 7/3 × 1/4
x = 7/12
The new reading on the gas gauge will be will be 7/12 full

5)Trevon's school is selling tickets to the annual dance competition. On the first day of ticket sales
the school sold 5 senior citizen tickets and 8 student tickets for a total of $94. The school took in
$164 on the second day by selling 10 senior citizen tickets and 13 student tickets. Find the price
of a senior citizen ticket and the price of a student ticket
Answer:
$8 for student tickets and $4.40 for senior tickets
Step-by-step explanation:
10 (5x +8y=94)
5 (10x +13y=164)
50x+80y=940
- 50x +65y=820
80y-65y= 940-820
15y= 120/15
y=8
(y is the cost of student tickets)
5x+8y=94
5x+8(9)=94
5x+72=94-72
5x=22/5
x= 4.4
