Find the Perimeter of each figure. Show your Solution.
(Note: No Solution considered wrong)
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

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:
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

The surface area of the figure is 720 square inches
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
Hence the surface area of the figure is 720 square inches

Find the y-intercept and the slope of the line.
Y=-4x-3
Slope:-
-4
y-intercept:-
(0,-3)
Solution:-The equation of this line is written in Slope-Intercept Form, which looks like so:-y=mx+bIn this formula, m stands for the slope of the line, and b stands for the y-intercept.Please remember that the slope is the line's rise (the amount of units we move up, or "rise" divided by its run (the amount of units we move left or right, and the y-intercept is the point where the line intersects the y-axis. (0, b)Also, please notice that m is the coefficient of x, and b is the constant.Therefore, the slope of the line is equivalent to -4, and the y-intercept is (0, -3).Hope it helps.
Do comment if you have any query.
Answer:
Slope: 4; y-intercept: -3
Explanation:
To find the slope of the line, we will look at the number in front of x.
That number is -4. Hence, the slope is -4
Now, the y-intercept is the constant.
The constant is -3.
Hence, the y-intercept is -3.

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.

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.”
