Answer:
457 pesos
Step-by-step explanation:
From the above question, we are told that:
David bought 23 pens and 15 pencils.
Each pen = 14 pesos
Each pencil = 9 pesos
The amount of money David spent in total =
(23 × 14 pesos) + (15 × 9 pesos)
= 322 pesos + 135 pesos
= 457 pesos
Therefore, David spent in total 457 pesos

A regular octagon with side length a cm can be made by cutting off
the four corners of a square board. How long should the sides of the
board be?
Answer:
one side = [tex]\frac{a\sqrt{2}}{2}[/tex]
Step-by-step explanation:
if you draw an octagon on a piece of paper, you can draw a square around it, you should be able to see a diagram of this attached, ignore the 6.
Let's say TP = a
since it's a regular octagon, TP = HT
and using the Pythagoras Theorem, we know a² + b² = c² and thus:
√(AT² + HA²) = HT
and since AT = HA which we will call x, the equation becomes:
√(2x²) = HT = a
rearrange the equation to solve for x and you get:
2x² = a²
x² = [tex]\frac{a^{2} }{2}[/tex]
x = [tex]\frac{a}{\sqrt{2}}[/tex]
which, if you rationalise the denominator, you get:
x = [tex]\frac{a\sqrt{2}}{2}[/tex]
A car motercycle leaves at noon from the same location, heading in the same direction. The average speed of the car is 30mph slower than twice the speed of the motorcycle.
Answer:
speed of motorcycle = 40 mph
speed of car = 50 mph
Step-by-step explanation:
Here is the complete question
A car and a motorcycle leave at noon from the same location, heading in the same direction. The average speed of the car is 30 mph slower than twice the speed of the motorcycle. In two hours, the car is 20 miles ahead of the motorcycle. Find the speed of both the car and the motorcycle, in miles per hour.
Speed = distance / time
This question would be solved using simultaneous equation
let m = average speed of the motorcycle
c = average speed of the car
c = 2m - 30 equation 1
20 =(c - m) x 2 equation 2
insert equation 1 into equation 2 and divide through by 2
10 = (2m - 30) - m
solve for m
m = 40 mph
substitute for m in equation 1
2(40) - 20 = 50 mph

Answer:
Andre scored 14 points
Step-by-step explanation:
D = A - 9
N = 2D = 10
2D = 10
D = 5
5 = A - 9

Which inequality represents the domain of the exponential piece?
A) x ≥ -1
B) x > 1
C) x > 3
D) x ≤ -2
Answer:
Step-by-step explanation:
The exponential piece is to the left, and starts at -2. So all its x values are less than or equal to -2

Convert 2 3/5 cups to pints.
Answer:
Decimal Form: 1.3
Exact Form: 13/10
Mixed Number Form: 1 3/10
Step-by-step explanation:
1 pint = 2 cups
Convert the mixed fraction into an improper fraction. 2 3/5 = 13/5 cups
You divide 13/5 by 2, since there are 2 cups in one pint, and you are trying to get pints. 13/5 divided by 2:
Decimal Form: 1.3
Exact Form: 13/10
Mixed Number Form: 1 3/10

given m||n,find the value of x
Answer:
8x+5 + 2x+5 = 180
10x+10=180
10x =170 = x = 17
Step-by-step explanation:
Answer:
answer: x = 17 Hope this helps!
2 x 17 + 5 = 39 8 x 17 + 5 = 141
Straight angles are 180 degrees
39 + 141 = 180
So x = 17

HELP I HAVE FSA GIVE ME SOME TIPSSS
Answer:
Plan ahead for medical expenses.
Spend your money.
Save your receipts.
Use your FSA to pay expenses your health plan doesn't cover.
Use your FSA to reach health plan financial milestones.
Know what your FSA covers.
Know your FSA balance.
Step-by-step explanation:
Answer:
Okay so I just took the FSA and my biggest tip is to just relax and don't overthink. Another tip that is kinda weird is to chew gum/mint. They normally hand it out to you but stopped for coronavirus. It helps you focus and it helps calm you. Make sure you double check your answers and if you don't know a question go back over it and re read it. Also pay attention to other questions because sometimes a question from the same passage helps you with a previous one. You're going to do well and good luck!

I need help please. Find 4 solutions of the equation (sin x)^2 = 1/4 for x between 0 and 360. Please show how you found it if not u will be reported.
Step-by-step explanation:
(sinx)²=1/4sinx=√1/4sinx =1/2sinx=sin30°x=30°hope it helps.
Answer:
x = 30, 150, 210, 330 degrees.
Step-by-step explanation:
(sin x)^2 = 1/4
sin x = +/- √1/4
sin x = +/- /2
In the first quadrant x = angle whose sine is 1/2 = 30 degrees.
There is also a solution in the other 3 quadrants.
In second quadrant where sine = 1/2 , x = 180-30 = 150 degrees,
In 3rd and 4th where sine x = -1/2 the angles are 210 and 330 degrees.
The dot plot shows the heights of the players on two basketball teams.
Which statement is best supported by these data?
