Sean determines that the triangle shown in the diagram has angle measures of 40°, 40°, and 100°. Is Sean correct?
Answers
So the remaining 2 angles are equal 80
As all angles in a triangle are equal to 180
X+5 + x - 5 =80
Simplify
2x=80
X=40
Soo one of the angles are 40-5 which is (35)
And the other is 40+5 which is (45)
So sean is not correct
~sorry sean teehee
Answer:
Step-by-step explanation:
The two angles add to 80 degrees. Two remote angles always equal the exterior angle not connected to them.
That means that
x + 5 + x - 5 = 80
2x = 80
x = 40
The base angle is
40 + 40 + y = 180
80 + y = 180
y = 100
Note
You could do this much quicker by noticing that
80 + y = 189
y = 100
No he is not right
The given 2 angles are x + 5 which is 45 and x - 5 which is 35
All he got correct was the fact that the third angle is 100 degrees.

A supermarket marks down the price of a $3.00 loaf of bread by 20%. What is the discount and the new price of the loaf of bread?
Answers
Answer:
new price= $2.40
Step-by-step explanation:
20%= 20/100= 1/5
$3.00/5= 00.60
1/5 of the price is being subtracted from $3.00
$00.60 is 1/5
3.00-.60= 2.40
Answer:
The discount is 20% off (you only have to pay 80% of the original price)
The new price of the bread is $2.40 (60 cents off)
Step-by-step explanation:
Because 20 goes into 100, 5 times I did 3.00/5
3.00/5= 0.6
Subtract 0.60 from the 3 dollars and that's it!
3.00-0.60= 2.40

His mistake is that he does not open the bracket first. The value of the x is negative of 4.
What is a BODMAS rule?BODMAS rule means for the Bracket, Order, Division, Multiplication, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Andre tried to solve the equation 1/4 ( x + 12 ) = 2.
First, open the bracket, then we have
[tex]\dfrac{x}{4} + \dfrac{12}{4} = 2[/tex]
On simplifying, we have
[tex]\dfrac{x}{4 } + 3 = 2[/tex]
Subtract 3 from both sides, we have
[tex]\dfrac{x}{4} = -1[/tex]
Multiply the equation by 4, we have

A box contains 6 red marbles, 4 green marbles, 3 blue marbles, and 2 yellow marbles. If Greg chooses one marble at random 300 times, how many times would he expect the marble to be blue?
Answers
Answer:
[tex]60[/tex] times
Step-by-step explanation:
There are [tex]6+4+3+2=15[/tex] marbles in total. Out of those, [tex]3[/tex] are blue, so the probability of pulling a blue marble is [tex]\frac{3}{15}=\frac{1}{5}[/tex].
