Answer:
8 cm
Step-by-step explanation:
You want the base of a triangle, given its height is 3 cm. From the base of 12 cm, the same triangle has a height of 2 cm.
AreaThe area of a triangle is given by the formula ...
A = 1/2bh
The area will be the same for any (base, height) pair of dimensions. The height is always measured perpendicular to the base. The base is generally one side of the triangle.
ApplicationHere, the longest side is labeled 12 cm, and the perpendicular distance to the opposite vertex (height) is labeled 2 cm. This means the triangle area is ...
A = (1/2)(12 cm)(2 cm) = 12 cm²
The distance perpendicular to the unknown side is shown as 3 cm. This gives you a clue that using the area of the triangle to find the unknown side is probably useful.
A = 1/2bh
12 cm² = 1/2(b)(3 cm)
8 cm = b . . . . . . . . . . . . multiply by 2/(3 cm)
The value that goes in the box is 8.

Find the volume of a cone with a height of 3.25 centimeters and
a diameter of 2.2 centimeters.
Answers
Answer:
As per Provided Information
Height of cone h is 3.25 cm
Diameter of cone is 2.2 cm
Radius = Diameter/2Radius = 2.2/2
Radius = 1.1 cm
We have been asked to determine the volume of the cone .
Using Formulae
[tex] \boxed{\bf \:Volume_{(Cone)} = \cfrac{1}{3} \pi {r}^{2}h}[/tex]
Substituting the given value and let's solve it
[tex]\sf\longrightarrow \: Volume_{(Cone)} = \cfrac{1}{3} \times 3.14 \times {1.1}^{2} \times 3.25 \\ \\ \\ \sf\longrightarrow \: Volume_{(Cone)} = \cfrac{1}{3} \times 3.14 \times 1.21 \times 3.25 \\ \\ \\ \sf\longrightarrow \: Volume_{(Cone)} = \cfrac{1}{3} \times 3.14 \times 3.9325 \\ \\ \\ \sf\longrightarrow \: Volume_{(Cone)} = \cfrac{1}{3} \times 12.34805 \\ \\ \\ \sf\longrightarrow \: Volume_{(Cone)} = \cfrac{12.34805}{3} \\ \\ \\ \sf\longrightarrow \: Volume_{(Cone)} = 4.11 {cm}^{3} [/tex]

Benjamin has 3 dimes and 4 nickels. What percent of a dollar does he have?
Answers
Answer:
50%
Step-by-step explanation:
Hope this helped
Maybe mark brainiest
Dime = 10 cents
Nickel = 5 cents
Total value of coins = 3(10) + 4(5) = 30 + 20 = 50
To find the percent, first create a fraction. The fraction will be the amount of money that Benjamin has over the total (one dollar).
50 / 100 = 5 / 10 = 0.5
0.5 x 100 = 50
50%
Answer: 50% of a dollar

(take 12 to 26)
so it will be 7(g-9)= 26-12
=> 7(g-9)= 14

Find a value for Y and give a reason for your answer
Answers
Step-by-step explanation:
inscribed angles subtended by the same arc are equal.
the central angle of a circle is twice any inscribed angle subtended by the same arc.
the first statement tells us that the 53° angle as well as y stay the same size no matter where on their arcs (between the 2 points connected to O) they would be. so, we don't need to bother with any line lengths.
the 2nd statement tells us that x = 2×53 = 106°. the 53° and x angles refer to the short arc on the right of the 2 points connected to O.
and y and x refer to the larger arc on the left of the 2 line connected to O. that means according to the second statement : 360-x (the big angle around O) = 2y
so,
360 - 106 = 2y
254 = 2y
y = 127°

1800 cm: 20 m in its simplest form is 9cm : 10 cm

Therefore, let's make the unit the same.
0.01 m = 1 cm
20m =

length = 2000 cm
Therefore, the ratio is as follows:
1800 cm : 2000 cm
