The diameter is 1 unit

Step-by-step explanation:

The circumference is 3.14 units

C = pi * d

Using 3.14 for pi

3.14 = 3.14 d

Divide each side by 3.14

3.14/3.14 = 3.14 d/ 3.14

1 =d

Answer: $550.00

Step-by-step explanation: Equation: I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 2%/100 = 0.02 per year,

then, solving our equation

I = 5500 × 0.02 × 5 = 550

I = $ 550.00

The simple interest accumulated

on a principal of $ 5,500.00

at a rate of 2% per year

for 5 years is $ 550.00.

Hope this helped! ;)

Answer:

Thus, the ratio of the central angles is 4 : 9.

Step-by-step explanation:

Area, A = 12 π square units

radius, R = 6 units

radius, r = 4 units

Area of sector is given by

[tex]A=\frac{\theta }{360}\times \pi r^{2}[/tex]

For first sector

[tex]12\pi=\frac{\theta }{360}\times \pi \times 6^{2}\\\\\theta = 120^{o}[/tex]

For second sector

[tex]12\pi=\frac{\theta' }{360}\times \pi \times 4^{2}\\\\\theta' = 270^{o}[/tex]

So, the ratio is

[tex]\frac{\theta}{\theta'}=\frac{120}{270} =4 : 9[/tex]

Answer:

4 : 9

Step-by-step explanation:

Given:

Two sectors, each has an area of 12pi, but with radii r1=6 and r2=4 units.

Find ratio of central angles.

Solution:

Let A = central angle

Area of a sector = pi r^2 (A/360)

Since both sectors have the same area,

pi r1^2 (A1/360) = pi r2^2 (A2/360)

simplifying

A1 r1^2 = A2 r2^2

Therefore

A1 : A2  = r2^2 : r1^2 = 4^2 : 6^2 = 4 : 9

Answer:

18 Caramel Centers

Step-by-step explanation:

Solution

So first off, we can group 2 and 3 toghether to make one "packet" with 5 candies in it. Now, we can divide 5 by 30 and get 6. Now we know how many packets/candies there are. After that, we can multiply 6 with 3 to get 18 caramel centers.

Verification:

2 x 6 = 12

3 x 6 = 18

12 + 18 = 30 ✅

============================================

Explanations:

Part (a)

The area of a triangle formula is A = 0.5*b*h where b and h are the base and height. You could use 1/2 in place of the 0.5

We're focused on the blue shaded triangle, which is the "floor" so to speak of this pyramid. To find the floor area, we will use b = 6 and h = 5.2 and we get

A = 0.5*b*h = 0.5*6*5.2 = 15.6

For this problem, all areas are in square inches as denoted by the [tex]\text{in}^2[/tex]

If you're curious where the b = 6 came from, it's because all sides of the equilateral triangle are the same length.

Note: The base and height of a triangle are always perpendicular.

----------------------

Part (b)

Focus on any single non-shaded triangle. Let's say we focus on the upper triangle. We have b = 6 and h = 4. It then leads to the area A = 12 sq in. This is the area of one lateral face.

------------------------

Part (c)

The instructions state that the lateral faces are congruent triangles, aka they are identical triangles. So that means we have three copies of the same area we found back in part (b), which was 12. Therefore, the lateral surface area is 3*12 = 36 square inches. As your teacher mentions, we do not include the shaded triangle as part of this result (that will happen in part d below).

------------------------

Part (d)

We add the results of parts (a) and (c) together to get the full surface area. This is the total area of the flat net, and it corresponds directly to the full surface area because we fold up the 2D figure to get the 3D one.

The total surface area is 15.6+36 = 51.6 in^2

--------------------------

Side note: Another name for "triangular pyramid" is "tetrahedron". The "tetra" means "four", and "hedron" means "face".

Step-by-step explanation:

ok please mark mr brainlist

Answer:

3%

Step-by-step explanation:

Interest rat is calculated by using the equation A = P(1 + r)^n

A is the amount after interest. Here, it is 1635.30

P is the principal, or base, amount. Here, it is 1422

r is the rate at which there is interest. It is what we need to find out.

n is the amount of years interest is calculated for. Here, it is 5

Now that we have everything, we calculate:

1635.30 = 1422(1 + r)^5

Now we have to get r on one side of the equation by itself:

Divide both sides by 1422:

1635.30/1422 = (1 + r)^5

5√(1655.30/1422) = 1 + r

5√(1.16406469) - 1 = r

Now r is on one side of the equation.

The 5th root of 1.16406469 is 1.03084987

1.03084987 - 1 = 0.0308, so it is 3%

The 5√ is the 5th root of the numbers

Or it's 2.835 percent I don't know

Answer:

The answer is three

Step-by-step explanation:

$11.50/10 = $1.15 per pound

$19.50/15 = $1.30 per pound

$1.15 * 20= $23

$1.30 * 20 =$26

$26- $23 = $3

answer: $3

Answer: You would spend $3 less at store A with 23 and Store B with 26

Step-by-step explanation: Store B: 15 pounds / 19.50 = $1.3*20 =$26

Store A: 10pounds =11.50*2=$23

Step-by-step explanation:

The probability that a person who walks by Tanisha has a pet- 0.8

The probability that a person who walks by Tanisha does not have a pet- 0.2

Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Probability of Event = Favorable Outcomes/Total Outcomes = X/n

Part A. The probability that a person who walks by Tanisha has a pet can be calculated by dividing the number of people who have a pet by the total number of people who walk by her. In this case, 16 out of 20 people have a pet, so the probability is:

P(having a pet) = 16/20 = 4/5 = 0.8

So, the probability that a person who walks by Tanisha has a pet is 0.8 or 80%.

Part B. The probability that a person who walks by Tanisha does not have a pet can be calculated by subtracting the probability of having a pet from 1. That is:

P(not having a pet) = 1 - P(having a pet)

P(not having a pet) = 1 - 0.8

P(not having a pet) = 0.2

So, the probability that a person who walks by Tanisha does not have a pet is 0.2 or 20%.
