If a perimetre of a rectangle is 38 cm and length is 12.5 cm What is the Area?
Answer:
81.25 cm^2
Step-by-step explanation:
perimeter = 2(l + w)
2(12.5 + w) = 38
12.5 + w = 38/2
w = 19 - 12.5
w = 6.5
Area = lw = 12.5 x 6.5 = 81.25
Answer:
81.25 cm²
Step-by-step explanation:
What is the area?The area is the total space taken up by a flat (2-D) surface or shape. The area is always measured in square units.
To solve for the perimeter of a rectangle, the expression is:
(Let p = perimeter, l = length, w = width)
(l × 2) + (w × 2) = pTo solve for the width of a rectangle when given the perimeter, we can use this expression:
(p - [l × 2]) ÷ 2 = wInserting 38 in for 'p' and 12.5 for 'l':
(38 - [12.5 × 2]) ÷ 2 = 6.5To check our work, we can use the expression to solve for the perimeter:
(6.5 × 2) + (12.5 × 2) = 38Because the perimeter matches up with 38, we know the width of the rectangle is 6.5cm.
To solve for the area of a rectangle, we use this expression:
(Let a = area)
l × w = aInserting 12.5 in for 'l' and 6.5 in for 'w':
12.5 × 6.5 = 81.25Therefore, the area of the rectangle is 81.25 cm².

In the given triangle, the measure of angle C is 32°
Calculating the measure of anglesFrom the question, we are to determine the value of angle C.
Let half of ∠IAB = a
and half of ∠IBA = b
Then,
a + b + 106° = 180° (Sum of angles in a triangle)
a + b = 74°
Also,
2a + 2b + ∠C = 180° (Sum of angles in a triangle)
2(a + b) + ∠C = 180°
2(74°) + ∠C = 180°
148° + ∠C = 180°
Subtract 148° from both sides
148° - 148° + ∠C = 180° - 148°
∠C = 32°
Hence, the measure of C is 32°

Find the value of x
Answer:
x = 18 !
Step-by-step explanation:
We can see that ∠CHD is equal to ∠GHF as they are vertically opposite angles. We can also see that the angles next to ∠CHD should all add up to 90° as it is a right angle!
This means that we have to add 32 and 32 then minus that from 90...
32 + 32 = 6490 - 64 = 26As the angle is the same we are now left with...
x + 8 = 26We just have to solve this by taking away 8 from both sides!
x + 8 - 8 = x26 - 8 = 18x = 18Hope this helps, have a lovely day! :)
Answer:
The answer is 18°, but please read the explanation so you can solve this problem in the future.
Step-by-step explanation:
To find the angle of x, we have to look at the angles in the first quadrant (in which the lines C and D are) first. To begin, a right angle is 90°. We see that there are two angles of 32° within the right angle (90°). Let's find the sum of 32 and 32.
32 + 32 = 64
Now, we can subtract 64° from 90° to find the angle of CD.
90 - 64 = 26
The angle between C and D is 26°.
If we look below at lines G and F, we can see that they are directly across from lines C and D, so they have the same angles. The arrow pointing to the angle of GF, which we know is 26°, says that x + 8° = 26°. To find x, let's subtract 8 from 26.
26 - 8 = 18
x = 18°

There is an equal amount of yellow, blue, green, and red marbles in a bag of 32 marbles. If Ed draws 4 marbles out of the bag with replacement, predict how many of the 4 marbles drawn should be blue.
1
4
8
32
Answer:
There are 32 marbles in the bag, and 1/4 of them are blue, so there are 32 * 1/4 = 8 blue marbles in the bag.
When Ed draws 4 marbles out of the bag with replacement, the probability of getting a blue marble on any given draw is 1/4.
The number of blue marbles Ed is expected to draw can be found by multiplying the probability of drawing a blue marble on each draw (1/4) by the number of draws (4):
Expected number of blue marbles = (1/4) * 4 = 1
Therefore, Ed is expected to draw 1 blue marble out of the 4 marbles drawn.
1) 1
Reasoning:
There are 4 different colors of marbles and 32 total marbles. 32/4 is 8, so there will be 8 of each at the start.
Because Ed picks 4 marbles, and there are 4 colors, we will divide 4 by 4 (4/4) and get 1.

How would the length of a circle change if:
a) the radius is increased 2 times
b) the radius is decreased 3 times
c) the diameter is increased 6 times?
Answer:
a) If the radius of a circle is increased 2 times, the length of the circle (circumference) will increase by a factor of 2π or approximately 6.28 times. This is because the formula for the circumference of a circle is C = 2πr, where r is the radius. If the radius is doubled, then the circumference will also be doubled.
b) If the radius of a circle is decreased 3 times, the length of the circle (circumference) will decrease by a factor of 6π or approximately 18.85 times. This is because the formula for the circumference of a circle is C = 2πr, where r is the radius. If the radius is divided by 3, then the circumference will also be divided by 3 and multiplied by 2π.
c) If the diameter of a circle is increased 6 times, the length of the circle (circumference) will increase by a factor of 6π or approximately 18.85 times. This is because the formula for the circumference of a circle is C = πd, where d is the diameter. If the diameter is multiplied by 6, then the circumference will also be multiplied by 6π
Step-by-step explanation:
pls Mark me As a brainlist
a) length of the circle increased by 2 times.
b) length of the circle decreased by 3 times.
c) length of the circle increased by 6 times.
Length of a circle that is the circumference of the circle is given by the formula = 2πr ( let's say C)
a) Given that the radius of the circle is increased by two times.
R = 2r
Required length of the circle = 2πR = 2π(2r) = 2×2πr = 2C
Hence, the length of the circle will be increased by 2 times.
b) Given that the radius is decreased by 3 times.
R= r/3
Required length of the circle = 2πR = 2π(r/3) = (2πr)/3 = C/3
Hence, the length of circle will be decreased by 3 times.
c) Given that the diameter of the circle is increased by 6 times.
D = 6d = 6×2r = 12r
Required length of the circle = πD= π×12r = 6(2πr) = 6C
Hence, the required length of circle will be increased by 6 times.

How to maximize the demand?The quadratic function representing the demand is given as follows:
y = -10x² + 60x + 180.
The vertex of a quadratic function is the point on the graph where the function reaches its maximum or minimum value. For a quadratic function in standard form y = ax² + bx + c, the x-coordinate of the vertex is given by:
x = -b / (2a)
The coefficients of the quadratic function in this problem are given as follows:
