Which one of these are polygons?
Answer:
f
Step-by-step explanation:
Answer: A, C (and F depending on the class)
Step-by-step explanation:
A polygon is a 2D shape with straight sides, with no curvature. B and E are curved, and D isn’t closed off. Depending on the class, the answer would also be F, but since it’s 3D, it’s a polyhedron.
Can someone explain how to do it aswell please and thank you
Answer:
B: 24ft^2
Step-by-step explanation:
Area of triangle = (base x height)/2
Step 1: form an equation
a = (12ft x 4ft)/2
Step 2: solve equation
a = 48ft^2 / 2
a = 24ft^2
*the base is the measurement for the bottom of a triangle while height is the measurement of the length from the bottom to the top of a triangle*
subtract 7 9/16 - 4 2/4
Answer:
3.0625 or 3 1/16
Step-by-step explanation:
So first Im just gonna subtract 7 - 4. (3)
So we multiply 9 by 4, and get 36.
Then we multiply 2 by 16, and get 32.
Next we give both terms new denominators -- 16 × 4 = 64.
Which yknow = 36/64 and 32/64.
Since our denominators match, we can subtract the numerators.
36 − 32 = 4 So it is 4/64..
Now we want to simplify so we divided by 2.
2/32 and 1/16
And we cant simplify It anymore because 2 is larger than 1.
So its 1/16th!! :D

Step-by-step explanation:
It's an overcast day in Hayward and you're waiting for AC Transit 97 Bus Line to show up. Your weather app says there's a 30% chance of rain that day. You know that if it rains, the probability that the bus runs late is 40%. If it doesn't rain, the probability that the bus runs late is only 15%. Use proper notation to state the probabilities. (a) What is the probability that it will rain and the bus will be late? (b) What is the probability that the bus will be late? (c) Given that the bus ran late, what was the probability that it was not raining?
Answer:
a
[tex]P(r n L) = 0.12[/tex]
b
[tex]P(L) = 0.225[/tex]
c
[tex]P(\= r | L) = 0.4667 [/tex]
Step-by-step explanation:
The chance that it will rain is [tex]P(r ) = 0.30 [/tex]
The chance that it does not rain is [tex]P(\= r ) = 1 - P(r ) [/tex]
[tex]P(\= r ) = 1 -0.30 [/tex]
[tex]P(\= r ) = 0.70 [/tex]
The probability that the bus run late if it rains is [tex]P(L | r) = 0.4[/tex]
The probability that the bus run late if it does not rain is [tex]P(L | \= r) = 0.15[/tex]
Generally the probability that it will rain and the bus will be late is mathematically represented as
[tex]P(r n L) = P(L | r) * P(r)[/tex]
=> [tex]P(r n L) = 0.4 * 0.30[/tex]
=> [tex]P(r n L) = 0.12[/tex]
Generally the probability that the bus will be late is mathematically represented as
[tex]P(L) = P(r) * P(L|r) + P(L | \= r) * P(\= r)[/tex]
=> [tex]P(L) = 0.30 * 0.4 +0.15*0.70[/tex]
=> [tex]P(L) = 0.225[/tex]
Generally given that the bus ran late, the probability that the bus it was not raining is mathematically represented as
[tex]P(\= r | L) = 1- P(r | L )[/tex]
Here [tex]P(r | L ) = \frac{P(r n L)}{P(L)}[/tex]
=> [tex]P(r | L ) = \frac{0.12}{0.225}[/tex]
=> [tex]P(r | L ) = 0.533 [/tex]
So
[tex]P(\= r | L) = 1- 0.533[/tex]
=> [tex]P(\= r | L) = 0.467 [/tex]
Inflation causes things to cost more, and for our money to buy less. Suppose inflation decreases the value of money by 1.1% each
year.
How much will $ 200 buy you in 14 years?
PLEASE HELP!!!
Answer: $171.31
Step-by-step explanation:
A = P(1 - r)ⁿ
Given: P = 200, r = 1.1% (.011), n = 14
A = 200(1 - .011)¹⁴
= 200(.989)¹⁴
= 171.308
Since we are talking about money, round to two decimal places.

The perimeter of the triangle below is 85 units. Find the length of side AC.
Write your answer without variables
Answer:
40 units
Step-by-step explanation:
Given:
Perimeter of ∆ABC = 85 units
AC = 4z
AB = 3z + 3
BC = z + 2
Required:
Numerical value of AC
SOLUTION:
Perimeter of ∆ = sum of all its sides
Perimeter of ∆ABC = AC + AB + BC
85 = 4z + (3z + 3) + (z + 2)
Use this equation to find the value of the variable, z
[tex] 85 = 4z + 3z + 3 + z + 2 [/tex]
Collect like terms
[tex] 85 = 8z + 5 [/tex]
Subtract 5 from both sides
[tex] 85 - 5 = 8z [/tex]
[tex] 80 = 8z [/tex]
Divide both sides by 8
[tex] 10 = z [/tex]
[tex] z = 10 [/tex]
AC = 4z
Plug in the value of x
AC = 4(10)
AC = 40 units

Math/Mechanics (please help! I have an exam tomorrow and desperately need practice!!!)
Answer:
Ta = 19.6 NTb = 12.74 NStep-by-step explanation:
Let A and B represent the angles that PA and PB make with the horizontal, respectively. Let Ta and Tb represent the tensions in PA and PB, respectively. Then for equilibrium, we have ...
Ta·cos(A) - Tb·cos(B) = 0 . . . . . horizontal equilibrium
Ta·sin(A) +Tb·sin(B) = T . . . . . . where T is the downward force exerted by P
__
The general solution of this pair of equations is ...
Ta = T·cos(B)/(sin(B)cos(A) +sin(A)cos(B)) . . . by Cramer's rule
which simplifies to
Ta = T·cos(B)/sin(A+B)
Tb = T·cos(A)/sin(A+B) . . . . by symmetry or Cramer's rule
If we call the position of the right angle point X, then the Pythagorean theorem tells us AX = 30 (3-4-5 triangle) and BX = 96 (5-12-13 triangle). Then the cable tensions are ...
Ta = T·(12/13)/(12/13·4/5 +3/5·5/13) = T·(20/21)
Ta = (2.1 kg)(9.8 m/s²)(20/21) = 19.6 N
Tb = T·(3/5)/(63/65) = T·(13/21)
Tb = (2.1 kg)(9.8 m/s²)(13/21) = 12.74 N
These tension values can be rounded to Ta = 20 N, Tb = 13 N.
_____
The weight of P is ...
F = Ma = (2.1 kg)(9.8 m/s²) = 20.58 N
Gregory is 4 times as old as his brother Nicholas. Their combined age
is 15. How old is each boy?
Answer:
Gregory is 11yrs old
Step-by-step explanation:
If you count down from 15 to 4 you get to the number 11 so if Gregory is 11 yrs then that means his brother is 7 yrs old.

C. 30
Answer: x=30
Step-by-step explanation:
Set them all equal to 180
so it would be 180=x+2x-1+3x+1
isolate x by adding or subtracting the 1
180=6x
x=30

what is the base 8 representation of the number 11100111
If the given number is in base 2, that means
11100111₂ = 2⁷ + 2⁶ + 2⁵ + 2² + 2 + 1
8 = 2³, and so we have
11100111₂ = 2 • (2³)² + (2³)² + 2² • 2³ + 2² + 2 + 1
11100111₂ = 3 • 8² + 4 • 8 + 7
11100111₂ = 347₈
Because 8 is the 3rd power of 2, we can also split up the given number into block of length up-to 3, then convert each block directly into base 8:
11 100 111
11₂ = 2 + 1 = 3
100₂ = 2² = 4
111₂ = 2² + 2 + 1 = 7
so again we get 347₈.

Scooter a cross-country skier skied at a rate of 10.82 miles per hour in 2.45 hours Des care covered 2.65 09 miles is this
correct explain why or why not
No, the estimate of 11 × 2 = 22 tells us that 2.6509 is too small and the decimal point is placed incorrectly. The product has four decimal places and should have been 26.5090, but a missing zero on the end caused the decimal to end up in the wrong position.
