Answer:
a. The area of a triangle is given by the formula A = (1/2)bh, where b is the base and h is the height. We know that A = 46cm^2 and b = 23cm. Substituting these values into the formula, we get:
46cm^2 = (1/2)(23cm)(h)
Simplifying, we get:
46cm^2 = 11.5cm*h
Dividing both sides by 11.5cm, we get:
h = 4cm
Therefore, the missing side of the right triangle is 4cm.
b. Using the same formula, we can find the height of the triangle:
120cm^2 = (1/2)(40cm)(h)
Simplifying, we get:
120cm^2 = 20cm*h
Dividing both sides by 20cm, we get:
h = 6cm
Therefore, the missing side of the right triangle is 6cm.
c. Again, using the same formula, we can find the height of the triangle:
12m^2 = (1/2)(20m)(h)
Simplifying, we get:
12m^2 = 10m*h
Dividing both sides by 10m, we get:
h = 1.2m
Therefore, the missing side of the right triangle is 1.2m.

the total number of spikes in the antlers of three male elks is 32. the oldest elk has four times as many spikes as the youngest elk. the second oldest elk has eight spikes more than the youngest elk. how many spikes does each elk have in their antler?
Answer as an X equation and find the X
Answer:
the oldest elk=4(x)
second oldest elk=x+8
youngest elk=x
total spikes=32
4x+x+8+x=32
6x+8=32
6x=32-8
6x/6=24/6
x=4.
the oldest elk =4(4)=16
Step-by-step explanation:
the youngest elk=4
the second oldest elk=4+8=12
16+4+12=32

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.

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.

The cost that will maximize the demand, considering the quadratic function, is given as follows:
$3.
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:
a = -10, b = 60.
The x-coordinate is the price that maximizes the demand, hence it is obtained as follows:
x = -60/(2 x (-20))
x = 3.

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°
