A zoo keeper was in charge of determining the population of meerkats at the zoo. He observed the meerkats and noted 8 of them and the special markings are on their face. The next day he went back out and observed the meerkats again. Out of the 20 that he saw, 4 of them were the same meerkats that he saw yesterday. How many meerkats can he assume are living at the zoo?
Answer:
16
Step-by-step explanation:
The zoo-keeper saw 8 special meerkats the day before and then only saw 4 special meerkats out of 20 the day after so 4 - 20 = 16.

one platter has 6 veggie wraps, 12 turkey wraps and costs 64.50 another platter has 8 veggie wraps 8 turkey wraps and costs $56
Which system of equations represents the situation if x represents the cost of a veggie wrap and y represents the cost of a turkey wrap?
A.12x + 6y = 568x + 8y = 64.50
B.6x + 12y = 64.508x + 8y = 56
C.x + 2y = 64.50x + y = 56
D.6x = 64.508y = 56
Answer: $3.25
Step-by-step explanation: The computation of the cost of a veggie wrap is shown below:
Let us assume the veggie strap be x
And the turkey wrap be y
Now the equations are
6x + 12y = $64.50
x + 2y = $10.75
8x + 8y = $56
x + y = 7
Now
x + 2y = $10.75
x + y = $7
y = $3.75
So x = $7 - 3.75
= $3.25
So, the correct option is option (B).
To understand the calculations, check below.
Linear simultaneous equation:Simultaneous linear equations are the system of two linear equations in two or three variables that are solved together to find a common solution. The simultaneous linear equation is represented as follows:
[tex]a_1x+b_1y=c_1\\a_2x+b_2y=c_2[/tex]
It is given that,
[tex]x[/tex] represents the cost of a veggie wrap and [tex]y[/tex] represents the cost of a turkey wrap.
Now, using the first part of the given question we get,
[tex]6x+12y=64.50...(1)[/tex]
Again in the second part of the given question is 8 veggies wraps 8 turkey wraps and costs $56 then we get the equation as,
[tex]8x+8y=56...(2)[/tex]
Then from equations (1) and (2) we get the equation as,
[tex]6x+12y=64.50\\8x+8y=56[/tex]

Answer:
y-intercept= 3/5
slope= - (2/5)
Step-by-step explanation:
To do this problem you have to convert standard form into slope-intercept
2x+5y=3---> y= - (2/5)x+3/5
From this, we could refer to the slope-intercept notation...
y=mx+b
m=slope
b=y-intercept
So...
Looking at this we get
y-intercept= 3/5
slope= - (2/5)

A tank can hold a maximum of 400 gallons of water. The volume of water when pumping water into the tank can be determined by the function f (m) = 12.5m + 25 where m is the number of minutes that the pump is running and f(m) is the volume of gallons of water in the tank. If the tank must maintain a minimum of 25 gallons of water, which inequality represents the domain of this situation?
(Hint: The variable f(m) is like "y" and m is like "x")
0 < m < 400
30 < m < 400
25 < m < 400
0 < m < 30
Inequalities help us to compare two unequal expressions. The inequality that represents the domain of this situation is 0<m<30.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
Given that the volume of the tank should be between 400 gallons of water to 25 gallons of water. While the function of the volume of the water is given as,
f(m) = 12.5m + 25,
Now to know the value of m for which the volume of water in the tank is 400 gallons.
[tex]f(m) = 12.5m + 25\\\\400=12.5+25\\\\375=12.5m\\\\m = 30[/tex]
Also, the value of m for which the volume of the water in the tank is 25 gallons is,
[tex]f(m) = 12.5m + 25\\\\25=12.5+25\\\\0=12.5m\\\\m = 0[/tex]
Hence, the inequality that represents the domain of this situation is 0<m<30.

Answer:
16
Step-by-step explanation:
To divide fractions we can use reciprocals and the rule keep, change flip.
First, we make 4 into the fraction 4/1.
Next, we make this a multiplication problem.
Then, we flip 1/4 to 4/1.
4/1 times 4/1 is 16/1, or 16.

Which are equivalent ratios to 2:3?
Check all that are true.
10:16
8:12
6:9
9:12
4:6
Answer:
8:12 6:9 4:6
Step-by-step explanation:
Divide each ratio by 2:3 and check if both numbers on either side of : are the same
For example:
8:12 divided by 2:3 = 4:4
Answer:
8:12, 6:9, and 4:6
Step-by-step explanation:
Equivalent ratios are any ratios that represent the same when they are simplified. All the ratios above simplify to 2:3. When the 8 and 12 of 8:12 are both divided by 4, the result is 2:3. When the 6 and 9 in 6:9 are both divided by 3, the result is 2:3. When the 4 and 6 in 4:6 are both divided by 2, the result is 2:3. The ratios 10:16 and 9:12 cannot be simplified to 2:3, and therefore are not correct answers.
