What is the approximate volume of the cone?
Use 3.14 for π.
A 1206 cm³
B 2170 cm³
C 3260 cm³
C 6510 cm³
Answers
Answer:
A. 1206 cm³
Step-by-step explanation:
We have a cone and are asked to find the approximate volume of it.
Keep in mind we are using π for 3.14
The forumla of a cone is V = πr²[tex]\frac{h}{3}[/tex]
We know the radius = 12
and the height = 8
Substitute :
V = π12²[tex]\frac{8}{3}[/tex]
Since these are multiplied with each other, we can first start off with multiplying the fraction, including with factoring 12²:
V = [tex]\frac{2^4*3^2*8\pi }{3}[/tex]
Cancel the common factor - 3 :
V = [tex]2^4 * 8 * 3\pi[/tex]
Multiply 8 and 3π :
V = [tex]2^4 * 24\pi[/tex]
Solve the exponent :
V = [tex]16 * 24\pi[/tex]
Multiply :
V = [tex]384\pi[/tex]
Multiply for the final answer :
1205.76 cm³
which can be rounded up to
A. 1206 cm³

90 - 43 = x
Step-by-step explanation:
Answer: 47
Step-by-step explanation:
Dude just subtract 43 from 90, since you are given a 90 degree angle.
But if you need the equation: 43+x-7=90
add 43 and (-7) which gives us 36
new equation is now: 36+x=90
move the 36 to the other side
x=54
now plug it in x(54)-7=47
A bakery buys a large bag of sugar that has 34 cups. They use 10 cups to make some cookies. They use the rest of the bag to make 144 giant muffins. Their customers want to know how much sugar is in each muffin.
Answers
Answer:
there would be 1 ÷ 6 sugar in each month
Step-by-step explanation:
The computation of the customers that want to know the sugar in each muffin is shown below
Here we assume the sugar in each muffin be x
Now there is 30 cups and 10 cups should be used for making some cookies
And, the rest would be use for making 144 gaint muffins
So, the equation that should be used is
10 + 144x = 34
144x = 24
x = 1 ÷ 6
So there would be 1 ÷ 6 sugar in each month

Answers
Answer:
[tex]\overline {DC}[/tex] = 7
[tex]\overline {BD}[/tex] = √35
[tex]\overline {AB}[/tex] = 2·√15
Step-by-step explanation:
Please find attached the drawing of right triangle ABC created with MS Visio
Let 'x' represent [tex]\overline {BD}[/tex] let 'y' represent [tex]\overline {DC}[/tex], and let 'z' represent [tex]\overline {AB}[/tex], we get;
5² + x² = z²...(1)
x² + y² = (2·√21)² = 84
x² + y² = 84...(2)
84 + z² = (5 + y)²...(3)
From equation (1), we have;
x² = z² - 5²...(4)
From equation (2), and equation (4), we have;
x² + y² = 84 = (z² - 5²) + y² = 84
∴ z² = 84 - y² + 5² = 109 - y²
z² = 109 - y²...(5)
From equation (3), and equation (5), we have;
84 + z² = (5 + y)² = 84 + (109 - y²) = (5 + y)²
84 + (109 - y²) = (5 + y)²
(5 + y)² - (84 + (109 - y²)) = 0
2·y² + 10·y - 168 = 0
y² + 5·y - 84 = 0
y = (-5 ± √(5² - 4 × 1 × (-84)))/(2 × 1)
y = 7, or y = -12
We note that 'y' is a natural number, therefore, the correct option of the two options is y = 7
y = [tex]\overline {DC}[/tex] = 7
From equation (2), we have;
x² + y² = 84
x² = 84 - y² = 84 - 7² = 35
x = √35
x = [tex]\overline {BD}[/tex] = √35
z² = 109 - y²
∴ z² = 109 - 7² = 60
z = √60 = 2·√15
z = 2·√15
z = [tex]\overline {AB}[/tex] = 2·√15.

<D = 137 degrees
Step-by-step explanation:
From the given diagram, the sum of the adjacent sides of the trapezoid is 180degrees. Hence;
<A +<B = 180
85 + <B = 180
<B = 180 - 85
<B = 95degrees
Similarly
<C + <D =180
43 + <D = 180
<D = 180 - 43
<D = 137 degrees

Explain how to use a number line to find the sum 7 + −2.
Answers
Step-by-step explanation:
start at 7 on the number line. move to the left (because the value is negative) 2 jumps. you will land on 5.
Answer: 5
Step-by-step explanation:
Usually you would just do 7+-2 which is also 7-2 which equals 5 but since it's a number line you do this
You would locate 7 on the number line and do the same for -2
Once done, you would take the distance 2 is from 0 and push 7 there(basically moving it to 5) and that would be how you would use a number line to find the sum of 7 + -2
Now if the 2 was positive, this would be different and you would add the distance making it 9 but since it's negative you push it towards 0 which makes it 5
I hope this helps!

Ten points! Teresa's family is thinking about buying a family pass to a gym. The pass is $120 for a family of 6. Individual passes are $25 each. How much money can Teresa's family save by purchasing a family pass instead of 6 individual passes?
Answers
Answer: If Teresa‘s family bought individual passes it would be $150 so then if you subtract it would be $30. Teres’s family saved 30 dollars.
Step-by-step explanation:
They can save $30
Step-by-step explanation:
If the family pass is $120 and individual passes are $25 dollars.
6 people times $25 dollars = $150
Family pass: $125
$150-$125=$30

Tangents C B and C B intersect at point C outside of the circle. A line is drawn to connect points C and O. We are given that angle AOB is a central angle of circle O and that angle ACB is a circumscribed angle of circle O. We see that AO ≅ BO because . We also know that AC ≅ BC since . Using the reflexive property, we see that . Therefore, we conclude that △ACO is congruent to △BCO by the .
Answers
Answer:
all radii of the same circle are congruent
tangents to a circle that intersect are congruent
side CO is congruent to side CO
SSS congruency theorem
Step-by-step explanation:
The triangle △ACO ≅ △BCO are congruent to each other by SAS postulate.
Given: ∠AOB is a central angle and ∠ACB is a circumscribed angle.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
We know that the radius and the tangent are perpendicular to each other.
Then the angle ∠CAO and angle ∠CBO are of 90°.
We know that the tangent of the circle drawn from the point outside the circle will be 2, and these tangent are of equal length.
In triangle △ACO ≅ △BCO, we have
CO = CO (Common side)
∠CAO = ∠CBO = 90°
OA = OB (Radius)
Thus, the triangle △ACO ≅ △BCO are congruent to each other by SAS postulate.

Juana is measuring two pyramids whose base are isosceles right triangles. The second pyramid has the same height, but has 9 times the volume. What is the side length of its base
Answers
9514 1404 393
Answer:
3 times the smaller triangle base
Step-by-step explanation:
The volume is proportional to the height and to the area of the base.
If the height is unchanged, the larger pyramid must have a triangular base with an area that is 9 times the smaller base area.
Since the bases are similar, the area ratio is the square of the side length ratio. The side lengths of the larger base triangle must be √9 = 3 times the side lengths of the smaller base triangle.
