Which lengths can be used, directly or indirectly, to calculate the volume of the hexagonal right pyramid? Select three options. XY and ST VU and TW XS and XW TX and WX VU and YZ
Answers
Answer:
XYand ST , VU and TW, TX and WX
Step-by-step explanation:
Volume of hexagonal right pyramid =[tex]\frac{1}{3}[/tex]×Area of base ×height
Area of base =[tex]\frac{1}{2}[/tex]×apothem ×perimeter
if we consider face TXY ,here height =ST and length XY
(b) consider face TVW, length VU and TW
(d) consider face TWX, length WX and TX
Hence lengths in options (a),(b),(d) can be used to find the volume of hexagonal right pyramid .

A. 23 square root 22b
B. 130 square root 22b
C. 3 square root b^2
D. 3 square root 22b
Answers
Given:
The expression is
[tex]13\sqrt {22b}-10\sqrt{22b}, b>0[/tex]
To find:
The equivalent expression.
Solution:
We have,
[tex]13\sqrt {22b}-10\sqrt{22b}[/tex]
Taking out common factors.
[tex]=(13-10)\sqrt {22b}[/tex]
[tex]=(3)\sqrt {22b}[/tex]
[tex]=3\sqrt {22b}[/tex]
The expression [tex]3\sqrt {22b}[/tex] is equivalent to the given expression.
Therefore, the correct option is D.

van purchased a DVD player on sale the original price was $171.50 the sale price was $149.37 what is the first step finding the percent markdown find the percent markdown
Answers
Answer:

Step-by-step explanation:
Given ;
Original price = 171.50
Sale price = 149.37
To find the % markdown :
Markdown = Purchase price - sale price
171.50 - 149.37 = 22.13
(Markdown / purchase price) * 100%
(22.13 / 171.50) * 100%
0.1290379 * 100%
= 12.90%

The first pack has a unit rate of $11.49/ 4 balls
=$2.8725
The second pack has a unit rate of $16.79/6balls
=$2.798 per ball
the third pack has a unit rate of $22.99/9balls

So, I would definitely go for the third pack since it has the least cost.
Lisa is buying a computer for $1,500. The sales tax rate is 8.5%. Which expression should be used to calculate t, the total cost for the computer including tax?
Answers
Answer:
t=$1627.5Step-by-step explanation:
Step one:
given data
price of computer= $1500
sales tax= 8.5%
Step two
Let us compute the amount in tax
tax= 8.5/100*1500
=0.085*1500
=$127.5
Let the total cost be t
hence
t=1500+0.085*1500
t=1500+127.5
t=$1627.5
Here are the marks of a student in four exams. 65 80 76 69 The student takes a fifth exam. His mean mark for the five exams is 70 Work out his mark in the fifth exam
Answers
Answer:
mark of the fifth exam = 60
Step-by-step explanation:
Mean = sum of all marks / number of exam
Mean = 70
Number of exam = 5
Let x =
Mean = sum of all marks / number of exam
70 = (65 + 80 + 76 + 69 + x) / 5
Cross product
70 × 5 = (290 + x)
350 = 290 + x
350 - 290 = x
x = 60
mark of the fifth exam = 60

The school is landscaping an area for a soccer field. If the
dimensions are 60 feet by 35 feet. What is the area of the soccer
field?
Answers
Answer: 2100 square feet
Step-by-step explanation: 60 x 35=2100
Answer:
2100 ft squared!
Step-by-step explanation:
The formula to find the area of a rectangle is L * W = A
Where A is the total area, and L and W are the dimensions.
Since we know what the dimensions of the rectangles are, we can replace L and W to find out the area. This will look like this: 60 * 35 = A
Now we just have to multiply 60 and 35 to find A. This will simplify to 2100, which means the total are of the rectangle, or in this case, the soccer field, is 2100 ft squared!

solve this inequality for x: -46 -8x >22.
Answers
Answer:
Step-by-step explanation:
The key to answering this is to know that the only time you'll change the direction of the sign is when you multiply or divide by a negative number.
-46 - 8x > 22
-8x > 22 + 46
-8x > 68
x < 68/-8 (we divided by -8 so the inequality changed direction)
x < -17/2
Step-by-step explanation:
-46 - 8x > 22: Original problem
-46 - 8x + 46 > 22 + 46: Bringing all the constants to one side of the inequality
-8x > 68: Simplification
x < 68/-8 : You have to flip the inequality symbol because you are dividing by
a negative number..
x< -8.5 : The answer!!!!!
Checking your answer....
-46 - 8x > 22 : Original problem
-46 - 8(-8.5) > 22 : Substitution
-46 + 68 > 22 : Simplification
22 > 22 : Answer check successful!!!
(22 is not greater than 22 but we know that the answer cannot be -8.5 because the inequality states that x is less -8.5. This process was only for the purpose of checking not for the purpose of proving)
Hope this helps!!!!
