4. Find the volume of the figure. The base is a square.
5. Find the volume of the figure. Leave the answer in the terms of pi

Answers

Answer:

A) 283500 ft³

B) 1057.26 π in³

Step-by-step explanation:

A) Volume of square based pyramid

= 1/3 × Area of the base × height

= 1/3 × (90 ft)² × 105 ft

= 283500 ft³

B) This figure is a composite figure

Step 1

Find the volume of the cone

=1/3 πr²h

r = radius = 8.5 in

h = height = 10 in

= 1/3 × π × (8.5 in)² × 10 in

= 240.83333333 π in³

≈ 240.83 π in³

Step 2

Find the volume of the cylinder

= πr²h

= r = radius = 8.5 in

h = height = 11.3 in

= π × (8.5 in)² × 11.3 in

= 816.425 π in³

≈ 816.43π in³

Volume of the figure = (240.83 π + 816.43 π) in³

= 1057.26 π in³

The fifth term of an arithmetic sequence is 96. Which rule could define the sequence?

Answers

Answer:

a+4d = 96

Step-by-step explanation:

Given:  fifth term of an arithmetic sequence is 96

This means,  a+4d = 96

Where, a is the first term in the series and d is the common difference,

Since, the terms is 5th therefore we can say that

a+4d = 96

a = 96-4d

Carlos earns $11 per hour at his job. Let z represent the number of hours he worked in May. Let y represent

the number of hours he worked in June. Which expressions represent the amount of money, in dollars, Carlos

earned in May and June? Select all correct answers.

Answers

Answer: 11z + 11y

Step-by-step explanation:

Carlos earns his pay by the hour. That means that to find the cash made in a given month, the formula is:

= Carlos payment per hour * Number of hours worked in a month

In May he worked z hours:

He earns $11 per hour and works z hours, expression for earnings for the month is:

= 11 * z

= 11z

In June he worked y hours:

= 11 * y

= 11y

The total he earned in both May and June is:

= 11z + 11y

The expressions represent the amount of money, in dollars, Carlos  earned in May and June is 11z + 11y.

Given that,

Carlos earns $11 per hour at his job. Let z represent the number of hours he worked in May. Let y represent  the number of hours he worked in June.

Based on the above information, the calculation is as follows:

For May it is 11z

For June it is 11y

So, total it should be

11z + 11y

Charles road his bike due west 17 miles, then turned due south and rode another 13 miles. About how far was he from his starting point?
a
17.5 mi
b
21.4 mi
c
13.6 mi
d
10.9 mi

Answers

Answer:

21.4 miles (Answer A)

Step-by-step explanation:

17 miles west and then 13 miles south can be represented by a triangle whose leg lengths are 17 miles and 13 miles respectively.  We use the Pythagorean Theorem to find the length of the hypotenuse of this triangle; the hypotenuse length is the straight line distance between starting and end points:

d = √(13² + 17²) miles, or d = 21.4 miles

2(2x - 3) + 6 = 4x How many solutions does the equation have? A. no solutions B. one solution C. two solutions D. infinitely many solutions

Answers

Answer:

D. infinitely many solutions

Step-by-step explanation:

to find how many solutions the equation have, we can solve it

here's the given equation:

2(2x-3)+6=4x

our goal is to isolate the variable onto one side

do the distributive property shown in the equation (multiply both 2x and -3 by 2)

4x-6+6=4x

combine like terms (add -6 and 6)

4x=4x

subtract 4x from both sides, as we still have the variable on both sides

0=0

0 is always equal to 0; that's an identity

if we get to a point in an equation where we get an identity as the answer (ex. 3=3 or in this case, 0=0), the answer is all real numbers, or infinitely many solutions

Answer:

D. Infinitely many solutions.

Step-by-step explanation:

Borox is loading a freight elevator with 12 boxes: 4 small, 5 medium, and 3 large. A small box and medium box together weigh 20 pounds; a medium box and a large box together weigh 28 pounds, and a large box with a small box weighs 24 pounds. What is the total weight of the 12 boxes?

Answers

Answer:

140 pounds

Step-by-step explanation:

let s == small box

m = medium box

= large box

the following 3 equations can be derived from the question

s + m = 20 equation 1

m + l = 28  equation 2

l + s = 24  equation 3

make m the subject of the formula in equation 1 and 2

m = 20 - s  equation 4

m = 28 - l  equation 5

equate equation 4 and 5

20 - s = 28 - l

l - s = 8  equation 6

solve equation 3 and 6 using simultaneous equation

l + s = 24  equation 3

l - s = 8  equation 6

subtract equation 6 from 3

2s = 16

s = 8

substitute for s in equation 1

8 + m = 20

m = 12

substitute for m in equation 2

12 + l = 28

l = 16

total weight = (4 x 8) + (5 x 12) + (16 x 3) = 140 pounds


Function 2
+ 4x + 1
Function _
has the larger maximum.
(Put 1 or 2 in the blank space)

Answers

Answer:

Function 2 has larger max value.

Step-by-step explanation:

We know that the graph of Function 1 has the maximum value of 1 at x = 4 by looking at the graph.

But since we don't know what the maximum value of Function 2 is (Because Function 2 isn't given as a graph but rather an equation.) which means that we have to find the maximum value of Function 2.

[tex] \large{f(x) = - {x}^{2} + 4x + 1}[/tex]

It is not necessary to find x-value for a function because we want to know which function has larger maximum value. We will be using the formula below.

[tex] \large \boxed{y = \frac{4ac - {b}^{2} }{4a} }[/tex]

As you may know, a max-min value is indeed y-value. From Function 2, we know the value of a, b and c from standard form y = ax²+bx+c

Substitute our a, b and c in the formula.

[tex] \large{y = \frac{4( - 1)(1) - {(4)}^{2} }{4( - 1)} } \\ \large{y = \frac{ - 4 - 16}{ - 4} } \\ \large{y = \frac{ - 20}{ - 4} = 5}[/tex]

Since our maximum value or y-value is 5 for Function 2. Since we also know that Function 1 has 1 as maximum value and Function 2 has 5 as maximum value. Therefore, Function 2 has larger maximum value.
