on the left side of the triangle, it says 12 cm, for the right side of the triangle, it says 17 cm, below the triangle, it says 12 cm. find the area of the triangle and answer the question in square cm.
Answer:
The area of this triangle is 72 cm².
Step-by-step explanation:
We know all 3 lengths of this triangle (12, 12, 17), but all we need to answer this question is sides a and b (12, and 12).
The formula to find the area of a triangle is A = bh/2. Substitute b and h for 12 and 12 respectively.
A = (12 * 12)/2
A = 144/2
A = 72 cm²
The area of the triangle is 72 cm².

Which method can be used to find the volume of a cone?1. The volume of a cone is; [tex]V = \mathbf{\frac{1}{3} \cdot \pi \cdot r^2 \cdot h}[/tex]
Therefore;
[tex]Volume \ of \ the \ cone \approx \frac{1}{3} \times3.14 \times 7^2 \times 14 \approx \mathbf{718 \, u^3}[/tex]
718 u³ is equivalent to S
2. Diameter of the cone, d = 24
Therefore;
Radius of the cone = 12
[tex]Volume \ of \ the \ cone \approx \frac{1}{3} \times3.14 \times 12^2 \times 28 \approx \mathbf{4220.2\, u^3}[/tex]
4220.2 u³ is equivalent to E
3. d = 11, and h = 12
Therefore;
r = 5.5
[tex]Volume \ of \ the \ cone \approx \frac{1}{3} \times 3.14 \times 5.5^2 \times 12\approx \mathbf{379.9\, u^3}[/tex]
379.9 u³ is equivalent to T
4. r = 3.2, and h = 10
Therefore;
[tex]Volume \ of \ the \ cone \approx \frac{1}{3} \times 3.14 \times 3.2^2 \times 10\approx \mathbf{107.2\, u^3}[/tex]
107.2 u³ is equivalent to G
5. r = 9, h = 15
[tex]Volume \ of \ the \ cone \approx \frac{1}{3} \times 3.14 \times 9^2 \times 15\approx \mathbf{1271.7\, u^3}[/tex]
1,271.7 u³ is equivalent to D
6. d = 4, and h = 6
Therefore;
r = 2
[tex]Volume \ of \ the \ cone \approx \frac{1}{3} \times 3.14 \times 2^2 \times 6\approx \mathbf{25.1 \, u^3}[/tex]
25.1 u³ is equivalent to A
7. r = 1.5, and h = 3
Therefore;
[tex]Volume \ of \ the \ cone \approx \frac{1}{3} \times 3.14 \times 1.5^2 \times 3\approx \mathbf{7.1\, u^3}[/tex]
7.1 u³ is equivalent to E
8. d = 30, and h = 34
Therefore;
r = 15
[tex]Volume \ of \ the \ cone \approx \frac{1}{3} \times 3.14 \times 15^2 \times 34\approx \mathbf{8,007\, u^3}[/tex]
8,007 u³ is equivalent to I
9. r = 5, and h = 8
[tex]Volume \ of \ the \ cone \approx \frac{1}{3} \times 3.14 \times 5^2 \times 8\approx \mathbf{209.3\, u^3}[/tex]
209.3 u³ is equivalent to H

(4)^5*(4)^-2
Answer:
64
Step-by-step explanation:
4^5 is 1024
(4)^-2 is 0.0625 or 1/16
So 1/16 * 1024 is 64
Answer:64
Step-by-step explanation:
4^5 is 4 multiplied by itself 5 times.
so: 4^5 = 1024
(4)^-2 = 1/16 or 0.0625
1024 * 0.0625 = 64

An aquarium is on sale for $59.50. If this price represents a 15% discount from the original price, what is the original price to the nearest cent?
Answer: The original price is $70.00
Step-by-step explanation:
The problem states that $59.50 is the discounted price, this means that it is not the 100% price of the aquarium. Since 15% is the discount, the remaining price is equivalent to 85% of the original price, which amount to $59.50.
100% - 15% = 85%
100% - 15% = $59.50
To get original price, we must divide the discounted price by its corresponding percentage.
$59.50 / 85% = original price
$59.50 / 0.85 = $70
To check, we must get the 15% equivalent amount from the original price.
$70 x 15% = $10.50 discount value
$70 - $10.50 = $59.50 discounted price
I hope it helps you
According to a Niclsen survey, 92% of consumers around the world say that they trust recommendations from
friends and family most, above all other forms of advertising. Suppose we took random samples of n = 100
consumers from this population and computed the proportion of consumers in each sample who trust
recommendations from friends and family most.
What will be the shape of the sampling distribution of the proportions of consumers who trust
recommendations from friends and family most?
Choose 1 answer:
Skewed to the left
©
Skewed to the right
Approximately normal
Uniform
Answer:
what grade?
Step-by-step explanation:
The shape of the sampling distribution of the proportions of consumers will be skewed to the left. Hence, option A is correct.
What is Probability?Probability is calculated as the proportion of favorable events to all potential scenarios of an event. The proportion of positive results, or x, for an experiment with 'n' outcomes can be expressed.
As per the given information in the question,
Proportion = 92% = 0.92
Sample size, n = 100
As,
np = (100)(0.92) = 92
Use the equation given below,
n(1 - p)
= 100(1 - 0.92)
= 100 - 92
= 8
n(1 - p) = r < 10
When sampling distribution have fewer than 10 expected failure per sample, distribution of sample is left skewed.

Answthe answer is A 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 = 9/2
Step-by-step explanation:
see how the dominator is 2 just like the question 9/2 so u add all the numerators which is one and get 9/ now add the denominator /2 that gives you 9/2
Whats the least common demominator of 12,11,and 5
Answer: 660
Step-by-step explanation: To find the LCM or least common denominator, you have to find the prime numbers that all the numbers share. In this example, these numbers would be 2, 3, 5, and 11. However, 2 appears twice, therefore, when multiplying you must do 2*2*3*5*11 to get 660. hope that helps!
What’s the rate of change of this table?
Answer:
the average rate of change would 2
Step-by-step explanation:
to find the ARC you need two points (3,6) and (5,10) and to know how to find the ARC. it is quite easy if you use the equation (y2 - y1)/(x2 - x1). now you know what the equation to solve for ARC so you can place the points in:
(y2 - y1)/(x2 - x1)
(10 - 6) / (5 - 3)
(4) / (2) = 2
so the ARC would equal 2
