The net of a square pyramid is shown below:
Answer:
A. 16 in²Step-by-step explanation:
Total surface area is the sum of areas:
S = 2² + 4*(1/2)*2*3 = 16 in²Correct choice is A
Answer:
Required Answer :-Surface Area = (2)² + 4 × ½ × 2 × 3
Surface Area = 4 + 4 × ½ × 2 × 3
Surface Area = 4 + 2 × 2 × 3
Surface Area = 4 + 12
Surface Area = 16 in²
Decide if the sequence is arithmetic, geomtric, or neither. After you determine the type of sequence find the term given below. 2, 8, 32, 128 . . . Find a subscript 10 space
Answer:
Geometric sequence
[tex]a_{10} = 524288[/tex]
Step-by-step explanation:
Given
[tex]a: 2,8,32,128...[/tex]
Solving (1): The type of sequence
To check for arithmetic sequence:
[tex]d = a_2 - a_1[/tex] --- common difference
[tex]d = 8 - 2 = 6[/tex]
[tex]d =a_3 - a_2[/tex]
[tex]d =32-8=24[/tex]
Both values of d are not the same; Hence, the sequence is not arithmetic
To check for geometric sequence:
[tex]r = \frac{a_2}{a_1}[/tex] --- common ratio
[tex]r = \frac{8}{2}=4[/tex]
[tex]r = \frac{a_3}{a_2}[/tex]
[tex]r = \frac{32}{8} = 4[/tex]
[tex]r = \frac{a_4}{a_3}[/tex]
[tex]r = \frac{128}{32} = 4[/tex]
All values of r are the same.
Hence, it is a geometric sequence
Solving (2): Find [tex]a_{10[/tex]
For a geometric sequence;
[tex]a_n = a_1 * r^{n-1[/tex]
[tex]a_{10} = 2 * 4^{10-1[/tex]
[tex]a_{10} = 2 * 4^9[/tex]
[tex]a_{10} = 524288[/tex]

Jenny walked 2 miles on Monday and 1 miles on Tuesday. How many 3 8 7 8 miles did she walk on Monday and Tuesday all together?
Correct Question is:
Jenny walked 2 3/8 miles on Monday and 1 7/8 miles on Tuesday. How many miles did she walk on Monday and Tuesday all together? What number model would you use?
a. 2 3/8 - 1 7/8
b. 2 3/8 + 1 7/8
c. 23/8 + 17/8
d. none of these
Answer:
b. 2 3/8 + 1 7/8
Step-by-step explanation:
As the sum of both Monday and Tuesday miles are required therefore both fractions will be added up as mentioned in option B of the question.
remaining are wrong as both fractions cannot be subtracted, and option c is wrong because 2 (3/8) is not equals to 23/8 and 1 (7/8) is not equals to 17/8.

Find the slope of the line that contains the
point (4, −9) and has a y intercept of 2.
Answer:
m = -¹¹/₄Step-by-step explanation:
The equation of a line with slope of m and y-intercept of b is: y = mx + b
b = 2 and line contains the point (4, -9), so:
-9 = m×4 + 2 {subtract 2 from both sides}
-11 = 4m {divide booth sides by 4
m = -¹¹/₄

( 2 4/5 * 1 3/10) * 1 1/2
Answer:
( 2 4/5 * 1 3/10) * 1 1/2 = 5 23/50
Step-by-step explanation:
( 2 4/5 * 1 3/10) * 1 1/2 = 14/5 x 13/10 x 3/2 = 546/100 = 5 46/100 = 5 23/50

Have a great day! Can u mark me as brainlist? :)
Happy to help, and I get why you didn't get it
You could always ask g.o.o.g.l.e lol
-2.1 - 1 1/2 = 0.6
-2.1 - 0.6 = -1 1/2

An urn contains: 2 yellow balls, 1 red ball and 3 green balls.
We draw a ball:
What is the probability of getting:
1) a yellow ball:
2) a red ball:
3) a green ball:
4) a red ball or a green ball?
Answer:
Step-by-step explanation:
2 yellow balls
1 red ball
3 green balls
So in total there are 6 balls all together
1) 2/6 = 1/3
2) 1/6
3) 3/6 = 1/2
4) 3+1 = 4 4/6 = 2/3
Answer:
My big green balls is the answer because there big and large and can probably get in the way.
The answer is green also its just a joke.

Johnny is designing a playground model for a school project. the design below will be the foundation of his model. what is the area of the model John design? use 3.14 for p.
Answer:
586.17
Step-by-step explanation:
Area of triangle = 1/2 x base x height
[tex] = \frac{1}{2} \times 18 \times 7 \\ = \frac{1}{2} \times 126 \\ = 63 {cm}^{2} [/tex]
Area of Rectangle = Length x Width
[tex] = 22 \times 18 \\ = 396 {cm}^{2} [/tex]
Area of Semicircle =
[tex] \frac{1}{2} \pi {r}^{2} \\ = \frac{1}{2} (3.14)(9) {}^{2} \\ = 127.17cm {}^{2} [/tex]
Total Area = Area of Triangle + Area of Rectangle + Area of Semicircle
[tex] = 63 + 396 + 127.17 \\ = 586.17cm {}^{2} [/tex]

Determine the correlation coefficient (r) for the linear relationship below.
Answer:
X Values
∑ = 53.5
Mean = 10.7
∑(X - Mx)2 = SSx = 151.086
Y Values
∑ = 6.9
Mean = 1.38
∑(Y - My)2 = SSy = 3.788
X and Y Combined
N = 5
∑(X - Mx)(Y - My) = 23.711
R Calculation
r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))
r = 23.711 / √((151.086)(3.788)) = 0.9911
So r= 0.9911 or 99.11%
Pls help I don't understand
Answer:
Positive
Step-by-step explanation:
x is being multiplied by -27. To solve the equation, we need to divide both sides by -27. The number on the right side is -35. -35 will be divided by -27. The division of a negative number by a negative number gives a positive number, so the answer will be positive.
