Answer:

C, 290,837

Step-by-step explanation:

The 2 in his number is 10x the 2 in the number 328,907

This means you need to move the number to the left once, hence it being in the hundred thousands.

290,837 is the final answer.

Answer:

The answer is B.

Answer:

37 ft²

Step-by-step explanation:

The figure is composed of a triangle and a square

Therefore, area of the figure = area of the triangle + area of the square

= ½bh + s²

Where,

b = 1.5 + 4 + 1.5 = 7 ft

h = 6 ft

s = 4 ft

Plug in the values into the equation

Area of the figure = ½*7*6 + 4²

= 21 + 16

= 37 ft²

Answer:

D. Sarah does not have convincing statistical evidence to conclude that the population mean number of days for the plants to produce fruit is different from 87 days.

Step-by-step explanation:

The population mean, μ is given as 87

This population value is used to state the Null hypothesis ;

H0 : μ = 87

The alternative hypothesis is the opposite of the Null ; and hence, claims that the mean is different from the population mean, μ ≠ 87

H1: μ ≠ 87

The Decison level :

When Pvalue < α ; We reject the Null otherwise we fail to reject the null

The given p and α value :

P-value = 0.0752

α = 0.05

0.075 > 0.05 ; Hence ;

Pvalue > α ; We fail to reject the Null

We can thus conclude that there is not enough evidence to conclude that the population mean number of days for the plants to produce fruit is different from 87 days.

The value of f(4) is 3 if the graph of the function is shown in the picture, the answer is 3.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The graph of the function is shown in the picture.

From the graph the value of f(4) can be evaluated as follows:

y = f(x)

Plug x = 4

y = f(4)

From the graph:

Draw a vertical line from point 3 on the x-axis and when it cuts the curve draw a horizontal line when the line cuts the y-axis note the point.

y = f(4) = 3

Thus, the value of f(4) is 3 if the graph of the function is shown in the picture, the answer is 3.

Answer:

(0, -5) and (-16, -17)

Step-by-step explanation:

You can plug in the points into the function to test them.

(0, -5)

3(0) - 4(-5) - 8 = 12

20 - 8 = 12

12 = 12

(8, 2)

3(8) - 4(2) - 8 = 12

24 - 8 - 8 = 12

8 ≠ 12

(-16, -17)

3(-16) - 4(-17) - 8 = 12

-48 + 68 - 8 = 12

12 = 12

3(-1) - 4(-8) - 8 = 12

-3 + 32 - 8 = 12

21 ≠ 12

3(-40) - 4(-34) - 8 = 12

-120 + 136 - 8 = 12

8 ≠ 12

QN = 142°

A semicircle will always be equal to 180°, and we have two measures for semicircle QO.

Answer:

A

Step-by-step explanation:

Well B is strange. You might get them to make one complementary angle, but that has nothing to do with the Triangle sum theorem.

C is true. He is getting similar triangles, but that does not prove the Triangle sum theorem.  So -- don't choose C

D is just taking up space so you get 4 choices.

The answer should be A but the problem is the tips of the angles should all come to the same place. I think it does mean A, but it is a bit awkwardly worded.

Answer:

5,250 cm²

Step-by-step explanation:

Surface area of triangular prism = bh + (s1 + s2 + s3)L

Where ,

b = 24 cm

h = 35 cm

s1 = 37 cm

s2 = 37 cm

s3 = 24 cm

L = 45 cm

Plug in the values

Surface area = 24*35 + (37 + 37 + 24)45

= 840 + 4,410

= 5,250 cm²

Answer:

Step-by-step explanation:

The equivalent expression is,

⇒ 4a²b²c³ ∛b

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ ∛64a⁶b⁷c⁹

Now, We can simplify the expression as;

⇒ ∛64a⁶b⁷c⁹

⇒ ∛64a⁶b⁷c⁹

⇒ ∛4³ (a²)³ (b²)³ (b) (c³)³

⇒ 4a²b²c³ ∛b

Thus, The equivalent expression is,

⇒ 4a²b²c³ ∛b

Answer:12

Step-by-step explanation: I multiplied 3 times 4

The Lateral Surface Area of cone is 12  π  ft³

The lateral area of a cone is defined as the area covered by the curved surface of the cone. It is also called lateral surface area (LSA) or curved surface area (CSA) of a cone. A cone is a 3-D object which tapers smoothly from the flat circular base to a point. In other words, it is a shape formed by a set of line segments coming from the base that connects to a common point

example:

Find the lateral area of a cone having base radius of 21 units and height of 20 units. (Use π = 22/7)

Solution: Given that r = 21 units and h = 20 units

Thus, slant height of the cone, l = √(r2 + h2) = √(212 + 202) = √(441 + 400) = √841 = 29 units

We know, the lateral area of the cone = πrL

Lateral area of a cone = (22/7) × 21 × 29

= 22 × 3 × 29

= 1914 units2

Answer: The lateral surface area of the given cone is 1914 units2

Given:

l= 4 ft

r= 3 ft

Lateral area = πrl

Lateral area = π * 3 * 4

Lateral area = 12 π  ft³
