Answers
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
=> 18 cm

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?
Answers
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.”

What is the area of the circle with the equation 2x2 + 2y2 = 8?
show work pls !!
Answers
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]

The multiply the are with the height. 10.5 times 11 equals 115.5 cubic meters.
If the diameter is 11, then what's the radius?
Answers
EXPLANATION: The radius of a circle is the distance from the center of the circle to any point on the circumference.
The easiest way to find the radius is by dividing the diameter in half
1/2 x 11 = 11/2 OR 5.5
ANSWER: the radius of the circle 11 cm in diameter would be 5.5 cm.
If 7 4/5 of the total came to 109,200, what is the total?
Answers
7 and 4/5 also equals 39/5.
39 is what we call a prime number so we can’t factor 109200 with it, so all we have left that we can do is divide.
109200/39=$2800
$2800 is 1/5 of the total, so just multiply that by 5 and you have your answer!
2800x5=$14,000.

How to calculate the surface area of a ramp?The surface area of a figure is the sum of all the area of its faces.
For the given diagram, it consists of 2 triangular faces and 3 rectangular faces
Surface area= (5 * 24) + 2(13*12) + 24 * 12
Surfacee area = 120 + 312 + 288
Surface area = 720 square inches

Answer:
50 m
Step-by-step explanation:
We find the perimeter by adding all the sides of our figure.
The initial figure has perimeter :
P = 2 + 5 + 1 + 3 + 3 + 1 + 5
P = 20 m
The dilated figure with the scale factor of 2.5 has perimeter:
P = (2 + 5 + 1 + 3 + 3 + 1 + 5 ) · 2.5
P = 20 * 2.5 = 50 m

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)
Answers
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?
