Answer:
14 applesStep-by-step explanation:
Let
Number of apples = aNumber of students = sAccording to question we have equations
a = 3s + 2a = 4s - 2Find the number of students by substitution
3s + 2 = 4s - 24s - 3s = 2 + 2s = 4Find the number of apples
a = 3*4 + 2 = 12 + 2 = 14Answer:
14 apples
Step-by-step explanation:
Let x = number of students
Let y = total number of apples
Create a system of equations with the given information.
Equation 1
If she gave each student 3 apples, she would have 2 apples left:
⇒ y - 3x = 2
Equation 2
If she gave each students 4 apples each she would be 2 short:
⇒ y - 4x = -2
Rewrite Equation 1 to make y the subject:
⇒ y = 2 + 3x
Substitute this into Equation 2 and solve for x:
⇒ (2 + 3x) - 4x = -2
⇒ 2 + 3x - 4x = -2
⇒ 2 - x = -2
⇒ -x = -4
⇒ x = 4
Substitute the found value of x into the rewritten Equation 1 and solve for y:
⇒ y = 2 + 3(4)
⇒ y = 2 + 12
⇒ y = 14
Therefore, Mrs Reyes had 14 apples.

Scoopers ice cream shop sells one scoop of ice cream for $1.60. They sell three scoops for $4.80. How much money is needed to buy two scoops of ice cream?
Answer:
$3.20
Step-by-step explanation:
1.60 x 2 = $3.20
You need $3.20 to buy 2 scoops of ice cream.
Answer:
Step-by-step explanation:
Since the cost of one ice cream scoop is $1.60, you would either have to add $1.60 two times, or multiply 1.60x2.
$1.60+$1.60 or 1.60x2=$3.20.
Therefore, the answer to the question would be “$3.20 would be needed to buy two scoops of ice cream.”

Answer:
100 cm square?
Step-by-step explanation:
1 meter square = 100 cm square
Answer:
10,000 cm²
Step-by-step explanation:
m² to cm² conversion
1 m x 1 m = 1 m²But we know : [1 m = 100 cm]100 cm x 100 cm = 10,000 cm²Therefore, 1 m² = 10,000 cm²So, the surface area of the prism in cm² is 10,000 cm²
Mr. Blue's first year salary is $30,000 and it doubles each year. What is the explicit
rule for the sequence in simplified form? what is the recursive rule?
The explicit rule for the sequence in simplified form is y = 30000(2)^n
How to write the exponential functionThe standard exponential equation is expressed as:
y = ab^n
Given the following parameters
a is the initial values = 30,000
If the amount doubles each year then b = 2
Substitute the parameters
y = 30000(2)^n
Hence the explicit rule for the sequence in simplified form is y = 30000(2)^n
Learn more on explicit rule here: https://brainly.com/question/2059043
Answer: Explicit Rule: a_n=30,000 • 2^n-1 Recursive Rule: a_n = 2a_n-1; a_1 =30,000
Step-by-step explanation: the Explicit Rule for a geometric sequence is a_n = r • a_n -1 and the Recursive Rule is a_n = a_1 • a_n-1
a_1 is the first term and r is the common ration. In this case, the first term is 30,000 as stated in the question and the common ration is 2 since it doubles each time. So substitute those numbers into the formulas and that’s what you’ll get! Hope this helps! God bless you all!!
John goes to a restaurant and has a bill of $32.57 He uses a 10% coupon on the cost of the meal. The taxis 8%. He leaves a tip of 18% on the amount before the coupon or tax is applied. How much does he spend.
$37.52
I know it seems close, but the coupon doesn't do much when you repay a total of 18% before the coupon.

Send a voluntary on-line questionnaire to all Florida high school students.
Randomly select 2,500 high school students in the state of Florida.
Select all students in 20 schools, selected through random sampling.
Select all students in all Miami high schools.
Using sampling concepts, it is found that these following sample is biased.
Select all students in all Miami high schools.
What is sampling?It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.
In this problem, the only sample that does not englobe all of Florida is the one containing only students from Miami, hence the biased sample is:

what is the approximate value of x when f(x) = g(x)
Answer:
I'm a little confused by this question:
Lines and things that are linear are relatively boring in mathematics. What if my function f(x) = g'(x). I’m going to ask the same question in a different way.
What is an approximate value of g'(1.1)?
So I know L(x)=f(a)+f′(a)(x−a)
If I substitute items in, I get g′(x)+g′′(x)(x−x).
Since x−x=0 I always am going to end up with L(x)=g′(x)
I don't think this can be the right answer since I know the whole point is to use the 2nd derivative, but if you get 0 for (x−a), then the whole part ends up being 0. What am I missing here?
I'm completely lost here because these are the followup question after the one above:
Now things are interesting. Suppose g(1) = 0 and g'(1) = 1.
Use linear approximation to approximate the value of g(1.1). The answer to #2 and #3 gives us a slope of a tangent line and a value of a function, which we can use.
Use your previous answers to approximate the value of g(1.2). Somehow, this second derivative has caused an adjustment to our approximation.
What did using the second derivative do to the approximation?
Do you believe the approximation is better or worse than our original?

Find each real root.
Answer:
Step-by-step explanation:
I'm assuming the 7 is the question number.
The cube root is -2. There is only 1 real root.
You could find it this way. ∛(-8) = ∛-2 * - 2 * - 2
The rule for cube roots when the number has 3 roots that are the same is to take one outside the ∛ sign and discard the other 2.
-2 ∛1 The cube root of one is one.

What is the area of the circle with the equation 2x2 + 2y2 = 8?
show work pls !!
Answer:
4pi
Step-by-step explanation:
Divide through by two to get
x^2 + y^2 = 4 4 = radius squared radius = 2
area = pi r^2 = 4 pi
Answer: 4π
Step-by-step explanation:
Under the assumption that those are exponents, and your equation is:
[tex]2x^2+2y^2=8[/tex]
You first must turn this circle equation into standard form. The standard form for the equation of a circle is as follows:
[tex](x-a)^2+(y-b)^2=r^2[/tex]
For your case, the constants 'a' and 'b' are clearly zero. We have an annoying coefficient of 2 which can be cancelled by dividing both sides by 2:
[tex]x^2+y^2=4[/tex]
If you'd like, we can write this in the following way:
[tex](x-0)^2+(y-0)^2=2^2[/tex]
So, our circle is centered at the origin (0, 0) and has a radius of 2 units. The area of a circle is given by the formula:
[tex]A=\pi r^2[/tex]
[tex]A=\pi (2^2)=4\pi[/tex]

Answer:
1) 40 m; 2) 18 cm
Step-by-step explanation:
1) Length = 10 m
Breadth = 4 m
Perimeter of a rectangle
= length (l) × breadth (b)
= 10 × 4
= 40 m
2) Side 1 = 6 cm
Side 2 = 8 cm
Side 3 = 4 cm
Perimeter of a triangle
= Side 1 + Side 2 + Side 3
= 6 + 8 + 4
= 18 cm
_______
Hope it helps ⚜
Answer:
1. 28m
2. 18 cm
Step-by-step explanation:
Perimeter of rectangle = 2× (length + breadth )
=> 2 ( 10 + 4 )
=> 2 ( 14 )
=> 28 m
Perimeter of triangle = side a + side b + side c
=> 6cm + 8cm + 4cm
