Answers

Answer:

0.3440

Step-by-step explanation:

16 *0.215 = 80 = 160 = 32

80+160+32 = 3440

The solution of the product of the two numbers 1.6 and 0.215 will be 0.344.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the two numbers are 1.6 and 0.215. The solution of the numbers will be,

P = 1.6 x 0.215

P = 0.344

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

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]. However, this is only the probability of pulling a blue marble when [tex]1[/tex] marble is pulled at random.

Andre tried to solve the equation 1/4 ( x + 12 ) = 2. What was his mistake? Explain.

1/4x = -10
x = -40

Answers

Andre’s first mistake was that he didn’t distribute properly or at all. Instead of using the distributive property to get rid of the parenthesis, he moved the x to the 1/4 and subtracted 12 to the other side. Mistakes continue to occur from there so the equation solved would be:
1/4 (x+12)=2
1/4x+3=2
1/4x=-1
x=-4

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

[tex]x = -4[/tex]

More about the BODMAS rule link is given below.

Sean determines that the triangle shown in the diagram has angle measures of 40°, 40°, and 100°. Is Sean correct?

Answers

The bottom left angle is 180 -80=(100)

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.
