The circumference of the circle is given as 2[tex] \pi [/tex]r where [tex] \pi [/tex] is a constant whose value is equal to 22/7 and r is the radius of the circle
From the given problem, we have the circumference =37.7
2[tex] \pi [/tex]r = 37.7
2*22/7*r = 37.7
r = 37.7*7/(22*2)
r = 263.9/44
r = 5.99
r = 6cm
Radius = 6 centimeters (Rounded to nearest whole number)
30kx-6kx=8 solve for x
Answer:
1/3k
Step-by-step explanation:
30kx -6kx=8
We can operate the two terms in left because they are similar
24kx = 8
We divide by 8 both sides
3kx = 1
Finally, we divide by 3k both sides
x = [tex]\frac{1}{3k}[/tex]
Answer: x = 1/3k

Find the measure of the base angles in an isosceles triangle if the third angle measures 47° .... Show work please
Final answer:
Each base angle of the isosceles triangle measures 66.5°, found by subtracting the given angle from 180° and dividing the remainder by 2.
Explanation:
To find the measure of the base angles in an isosceles triangle when one angle measures 47°, we will use the fact that the sum of all angles in any triangle is always 180°.
Additionally, we know from geometry that in an isosceles triangle, the angles opposite the equal sides are equal. Applying these principles, we first subtract the given angle from the total sum of the angles:
180° (total angles in a triangle) - 47° (given angle) = 133°.
Now, since the remaining two angles are equal, we divide 133° by 2 to find the measure of each base angle:
133° ÷ 2 = 66.5°.
Thus, each base angle of the isosceles triangle measures 66.5°.

The density of glass is 2.6 g/cm3 and the density of lead is 11.3 g/cm3. Does this mean there are more particles of lead in 1 cm3 or that the lead particles are heavier than the glass particles? Give reasons for your answer.
A higher density means that lead is heavier than glass for the same volume, signifying that lead particles are both heavier and more numerous in a given volume than the glass particles.
Explanation:The density of a substance tells us how much mass is in a given volume, and it is expressed in g/cm³. Comparing the densities of glass (2.6 g/cm³) and lead (11.3 g/cm³), we can say that a given volume of lead is much heavier than the same volume of glass. This could mean either there are more lead particles or the lead particles are heavier. But from atomic physics, we know that individual lead atoms are indeed heavier than individual silica atoms (which make up glass). Therefore, the higher density of lead signifies that the lead particles are both more numerous and heavier in a given volume than the glass particles.

A construction company needs to remove 2 1/6 tons of dirt from a construction site. They can remove 7/8 tons of dirt each hour. What is the total number of hours it will take to remove the dirt?
It will take the construction company approximately 2 10/21 hours to remove the dirt.
Explanation:To find the number of hours it will take to remove the dirt, we need to divide the total amount of dirt by the amount of dirt that can be removed each hour. First, we need to convert the mixed number 2 1/6 tons to an improper fraction. 2 1/6 = 13/6 tons. Next, we divide 13/6 by 7/8 to find the number of hours:
13/6 ÷ 7/8 = 13/6 × 8/7 = 104/42 = 2 20/42 = 2 10/21
So, it will take the construction company approximately 2 10/21 hours to remove the dirt.
What is the value of y?
The value of [tex]y[/tex] in the given figure, using the rule of angle sum property and linear pair will be [tex]65\\[/tex].
According to angle sum property, the sum of all the sides of a triangle will be [tex]180^o[/tex].
A linear pair is defined as two neighboring angles that sum up to 180° or two angles which result in a line or a straight angle when combined, or it can be said that the sum of linear pair is supplementary.
In the given figure,
∠[tex]x + 130^o = 180^o \ \ \ (linear pair)\\\x = 50^o[/tex]
Now, In triangle ABC, using angle sum property:
[tex]A+B+C= 180^o\\50^o + y + y = 180^o\\50^o + 2y = 180^o\\2y = 130^o\\y = 65^o\\[/tex]
Thus, the value of [tex]y\\[/tex] in the given triangle is [tex]65^o\\[/tex].

the volume of a cylinder is 1,692.46 in cubed. if the radius becomes three times as large, what will be the cylinder's volume?
To find the new volume of the cylinder, multiply the original volume by 9.
Explanation:To find the new volume of the cylinder, we need to find the new radius first. Since the radius becomes three times as large, the new radius will be 3 times the original radius. Next, we substitute the new radius into the volume formula for a cylinder.
V = πr²h
Let's assume the original radius is 'r' and the original volume is 1,692.46 in³. Therefore:
1,692.46 = πr²h
The new radius will be 3r, so the new volume becomes:
V = π(3r)²h = 9πr²h
So, the new volume of the cylinder will be 9 times the original volume or 9 * 1,692.46 = 15,231.14 in³.

Tara has 2 bags of marbles. The first bag contains 6 red marbles,5 blue marbles and 4 green marbles.The second bag contains 3 red marbles,2 blue marbles, and 4 green marbles.Tara will randomly select 1 marble from each bag.What is the probability that Tara will select a blue marble from each bag?
Answer: Tara will have a 2/27 probability of choosing a blue marble from each bag
solution: First, we need to find the probability for the first bag using (p= number of outcomes/ total of outcomes), the number of outcomes is 5, and the total is 15, so our probability for bag 1 is 5/15.
Then, for the second bag, the number of outcomes is 2, and the total is 9, so the probability for the second bag is 2/9
To find the probability for both of the bags, we have to multiply them: 5/15 × 2/9= 10/135=2/27

ΔDEF rotates 90° clockwise about point A to create ΔD 'E 'F. Therefore, which equation must be true? m∠DEF = m∠D 'F 'E '
Final answer:
The equation m∠DEF = m∠D'F'E' must be true following a 90° clockwise rotation of ∆DEF, because rotations preserve angle measures.
Explanation:
When a geometric figure such as ∆DEF is rotated 90° clockwise about a point A, to create ∆D'E'F, corresponding angles in the two triangles will be equal. This is true because a rotation is a type of rigid motion, which preserves angle measures. The equation m∠DEF = m∠D'F'E' must be true because the angle at F in the original triangle ∆DEF becomes the angle at E' in the rotated triangle ∆D'E'F, given the preservation of angle measures through rotation.
Therefore, for such geometric transformations, it's crucial to understand that rotations do not alter the internal angles of the shape being transformed, which is consistent with the rules of plane geometry. This principle is useful in solving many problems that involve the rotation of figures within a plane.

mila wants to spend at least $20 on a classified ad in the newspaper. She has $12, how much does she need?
I need an equation with an inequality please:) thank you!
Mila needs at least $8 more to reach her goal of spending $20 on a classified ad. The inequality to represent this problem is x ≥ 8, where x is the amount of additional money she needs.
If Mila wants to spend at least $20 on a classified ad and currently has $12, we need to figure out how much more money she needs. We denote the amount of money she needs with the variable x. An inequality that represents this situation is:
12 + x ≥ 20
Subtracting 12 from both sides of the inequality to isolate x, we get:
x ≥ 20 - 12
x ≥ 8
So, Mila needs at least $8 more to have enough for the classified ad.

Josiah has two letters. The first weighs 2.9 ounces, and the second weighs 4.1 ounces. What is the total amount Josiah can expect to pay for postage?
$1.62
$1.64
$1.84
$2.04
Answer:
Total amount Josiah can expect to pay for postage is:
$ 1.84
Step-by-step explanation:
cost of mailing one letter in the country is:
f(x)=0.42 + 0.20[x-1]
The first weighs 2.9 ounces, and the second weighs 4.1 ounces.
Cost of mailing first letter=0.42+0.20(2.9-1)
=0.42+0.38
=$ 0.8
Cost of mailing second letter=0.42+0.20(4.1-1)
=0.42+0.62
=$ 1.04
total cost=$(0.8+1.04)
=$ 1.84
Hence, total amount Josiah can expect to pay for postage is:
$ 1.84
