Answer:
V = 211.56 mm
Step-by-step explanation:
The volume of a pyramid :
V = 1/3(Lenght * width * height)
Length = 9mm
Width = 8.2 mm
Height = 8.6 mm
Hence, we have ;
V = 1/3(9 * 8.2 * 8.6)
V = 1/3 * 634.68
V = 211.56 mm

Step-by-step explanation:
s+1+2s-1+90=180 degree(being linear pair)
3s+90=180
3s=180-90
s=90/3
s=30 degree
Answer:
s = 30
Step-by-step explanation:
the total angle is a straight angle that's composed of a right angle and 2 unknown angles.
straight angle = 180°right angle = 90°
(s + 1) + 90 + (2s- 1) = 180
s + 2s + 90 + 1 - 1 = 180
3s = 180 - 90
3s = 90
s = 90/ 3
s = 30

A laptop has a listed price of $891.99 before tax. If the sales tax rate is 9.25%, find the total cost of the laptop with sales tax included.
Round your answer to the nearest cent, as necessary.
Please explain to me.
Answer:
$974.50
Step-by-step explanation:
The sales tax is 0.0925($891.99), or $82.51. We need only add this amount to the listed price ($891.99) to find the total cost with sales tax included:
$891.99
+ 82.51
--------------
$974.50
An alternative approach would be to multiply the listed price by 1.0925:
1.0925($891.99) = $974.50
Here the '1' refers to the listed price and the '0.0925' to the sales tax.

Answer:
[tex]\lim_{x \to \(-1} f(x)=-2[/tex]
Step-by-step explanation:
In order for a limit to exist in a piecewise function, both its right-side and left-side limits must be equal to each other:
So, if we plug in x=-1 for the left side limit, we get 2cos(πx) = 2cos(π(-1)) = 2cos(-π) = 2(-1) = -2Plugging in x=-1 for the right-side limit, we get 2/cos(πx) = 2/cos(π(-1)) = 2/cos(-π) = 2/(-1) = -2Since both the right-side and left-side limits are equal to each other, we can say that the limit of f(x) as x approaches -1 is -2, therefore the limit existsSee the attached graphCan you explain how you answered it thank you!
x=
y=
Answer:
x = 1.5 or 1 1/2
y = 8
Step-by-step explanation:
Solving for x:
2x + 1/2 y = 7
6x - 1/2y = 5
Add both equations:
2x + 1/2 y + 6x - 1/2y = 7 + 5
8x = 12
x = 1 1/2
Solving for y:
2x + 1/2y = 7
We know x, so lets input
2(1.5) + 1/2y = 7
3 + .5y = 7
0.5y = 4
y = 4*2
y = 8
Check with the other equation
6x - .5y = 5
6(1.5) - 0.5y = 5
9 - 0.5y = 5
0.5y = 9 - 5
0.5y = 4
y = 4 * 2
y = 8

Chen is playing a game that requires each player to spin an arrow to one of four colors, equally divided: green, orange, purple, or yellow.
Four players before Chen spun the arrow to purple, but Chen really wants her arrow to land on green. How is the probability of Chen’s spin affected by the spins of previous players?
Chen's probability of landing on purple is increased because the previous players all landed on green.
Chen's chances of landing on purple are not affected by the other players landing on green.
Chen's probability of landing on purple is decreased because the previous players all landed on green.
Answer:
1/4
Step-by-step explanation:
They are equally divided and there are a total 4 sections.
To find probability for yellow:
Numerator : how many yellows sections there are
Denominator : total sections there are
Therefore, the probability would be 1 in 4 chances.

A
104 square inches
B
120 square inches
C
136 square inches
D
168 square inches
Answer:
That's a Trapezium
Area =½( A + B)x H
A and B are the top and bottom of the shape.
H is the height.
Substituting...
Area = ½(13+17)8
=120 Square Inches
Answer:
B. 120 in.²
Step-by-step explanation:
13 × 8 = 104 in.²
17 - 13 = 4
4 × 8 = 32
32 ÷ 2 = 16
16 in.² + 104 in.²
120 in.²

Answer:
[tex]\lim_{x \to 3} g(x) = DNE[/tex]
Step-by-step explanation:
Observations:
As x approaches 3 from the left side, f(x) approaches -1.6 As x approaches 3 from the right side, f(x) approaches 1.6Conclusion:
Because the right and left-side limits are not equal to each other, the limit does not existTherefore, [tex]\lim_{x \to 3} g(x) = DNE[/tex]Answer:

What is the value of b in the equation 3b - 4 = 11?
Answer:
b = 5
Step-by-step explanation:
3b - 4 = 11
Add 4 to each side
3b - 4+4 = 11+4
3b = 15
Divide each side by 3
3b/3 = 15/3
b = 5
Answer:
b = 5
Step-by-step explanation:
3b - 4 = 11
3b - 4 + 4 = 11 + 4
3b = 15
3b ÷ 3 = 15 ÷ 3
b = 5

Leo is working part time as a server in a restaurant. He makes $8.14 for each hour he works, and on average earns an additional $300 per week in tips. Which function, f(x), can Leo use to model his average weekly salary in terms of the number of hours, x, he works?
Answer:
f(x) = 8.14x + 300
Step-by-step explanation:
The function of 8.14x + 300 can be used to model Leo's average weekly salary in terms of x.
What is a function?' A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.'
According to the given problem,
Amount Leo earns for each hour he works = $8.14
Amount Leo earns in x hours = $8.14x
Amount Leo earns as additional tip per week = $300
Therefore, the function of x is,
⇒ f(x) = 8.14x + 300
Hence, we can conclude, the function that can be used to model his weekly salary is 8.14x + 300

Drink sales for an afternoon at the school carnival were recorded in the table below.
What is the experimental probability that the next drink is a small coffee? Enter your
answer as a simplified fraction.
Given:
The table that represents the drink sales for an afternoon at the school carnival.
To find:
The experimental probability that the next drink is a small coffee.
Solution:
From the given table it is clear that,
The total number of drinks sold = 72+99+63+68+47+58
= 407
The number of small coffee sold = 63
Now, the experimental probability that the next drink is a small coffee is:
[tex]\text{Probability}=\dfrac{\text{Number of small coffee sold}}{\text{Total number of drinks sold}}[/tex]
[tex]\text{Probability}=\dfrac{63}{407}[/tex]
It cannot be simplified further.
Therefore, the experimental probability that the next drink is a small coffee is [tex]\dfrac{63}{407}[/tex].

Step-by-step explanation:
If you were to pick one day of the year at random, is it more likely that the day would be a Tuesday or that the day would fall during the month of January?
Answer and explain in your own words why you chose what you chose.
Answer: It's more likely it's a Tuesday
========================================================
Explanation:
The odds of it being a Tuesday is 1/7 since there's 1 day of the week that's Tuesday out of 7 total.
The odds of it being January is 1/12 because we have 1 month we want out of 12 total.
Now the question is: which fraction is larger?
For now, assume they are equal. We'll cross multiply like so
1/7 = 1/12
1*12 = 7*1
12 = 7
We get a false statement at the end, but we can fix things by replacing the equal sign with a greater than sign to get this new set of steps
1/7 > 1/12
1*12 > 7*1
12 > 7
which leads us to a true statement. Therefore, 1/7 is the larger fraction and the more likely event.
-----------------
Alternatively, you can use your calculator to find that:
1/7 = 0.143 approximately1/12 = 0.083 approximatelyThen for each decimal, move the decimal point 3 spots to the right. The values 0.143 and 0.083 become 143 and 83 respectively. We can see that 143 is larger, which means 0.143 is larger, and lastly 1/7 is larger. Think of it like a chain.
