What was Miguel's mistake if any?
Answers
Answer:
Step-by-step explanation:
According to my answer, he shound have computed 2^3 which is 8 and suibstract that from four getting four, then multiplying it by tow to get eight so it should be 4 so Miguel made no mistakes.Since he was doing the order of operations for each step of the equation.
Answer:
C. Miguel incorrectly multiplied before dividing in step 3.
Step-by-step explanation:
32 ÷ 2(2³ - 4)
Solving parenthesis and exponent.
32 ÷ 2(8 - 4)
32 ÷ 2(4)
The division is first, then multiplication.
32/2 (4)
16(4)
= 64

check each option
1st one: obtuse triangle
osbuse means that the triangle has an angle more than 90 degrees
remember that all angles add to 180
90 is one
90+D+F=180
D+F=90
so those 2 mystery angles both have to be less than 90 so therefor none of them can be obtuse
not 1st option
2nd: angle at D is acute
acute means less than 90
so we remember that
D+F=90
no angle can be 0 so let's say F is a very small number like 0.0001
then D would be 89.9999
still less than 90, it is acute
this 2nd optin is right
3rd: angle at F is obtuse
wrong, from 1st one, no obtuse angles
3rd option is wrong
4th: right triangle
duh, a right triangle has a right angle in it
90 degrees is a right angle
yes
4th optin is right
5th: D is obtuse
naw, fam. no obtuse angles here
the right answers are 2nd and 4th or

cost/amount is constant
1235/95=x/285
cross multiply or time both sides by (95 times 283)

divide oth sies by 95
3705=x
the cost is $3705

To make this process simpler, we can start off my translating both values into decimals.
In order to change a percentage into a decimal, you can either divide the percentage by 100, or (my personal shortcut) just shift the decimal point over two places to the left.
10% = 0.1
Now, onto the fraction.
To change
3 / 8 = 0.375
Now, we can reattach the whole number to get our entire decimal:
2.375
From here, we can multiply these two values to get our answer:
0.1 * 2.275 = 0.2375
which is the decimal form of our answer. In order to find the fractional form, we must simply put all of the numbers to the left of the decimal point as the numerator of a fraction, with a multiple of 10 with as many zeros as there are numbers to the left of the decimal point as the denominator.
0.2375 =
And we can reduce this fraction heavily by dividing out like terms. For the sake of time, I will eliminate this step to tell you that the finished reduction shows us a fraction of
So there you have it.
10% of 2
