Evaluate the expression 90 = [(82 - 77).91
Answers
Answer:
See below.
Step-by-step explanation:
Since there is an equal sign, this is not an expression. It is an equation. If you evaluate the right side, you'll see that it is a false equation since both sides are not equal to each other. Also, there is a bracket missing.
90 is not equal to 4.55.
Maybe it is meant to be the following expression:
90 + [(82 - 77).91] = 90 + 5(0.91) = 90 + 4.55 = 4.55
Or maybe this one:
90 - [(82 - 77).91] = 90 - 5(0.91) = 90 - 4.55 = 85.45

39. Make Sense and Persevere A company
manufactures cell phone cases. The length
of a certain case must be within 0.25 mm of
125 mm, as shown (figure is not to scale). All
cases with lengths outside of this range are
removed from the inventory. How could you
use an absolute value inequality to represent
the lengths of all the cases that should be
removed? Explain.
Answers
An absolute value inequality is used to represent the situation given that
cases with values above and below the allowance are to be removed.
The absolute value inequality for the situation is; |x - 125| ≥ 0.25.Reason:
The given parameter are;
Length of a case x ≤ 125 + 0.25
Length of a case x ≥ 125 - 0.25
Required:
Represent the cases that are to be removed using absolute inequality.
Solution:
The given inequalities sign can be rearranged to give the cases to be
removed as follows;
x ≥ 125 + 0.25
∴ x - 125 ≥ 0.25...(1)
x ≤ 125 - 0.25
x - 125 ≤ -0.25
Multiplying both sides by (-1) gives;
-1×(x - 125) ≥ (-1) × -0.25 = 0.25
-(x - 125) ≥ 0.25...(2)
Therefore;
The given that a case with difference (x - 125) ≥ 0.25 or when (x - 125) is
negative -(x - 125) ≥ 0.25 should be removed, using absolute inequality, we
have;
|x - 125| = (x - 125) when x > 125
|x - 125| = -(x - 125) when x < 125, and (x - 125) is negative
Which gives; A case with length |x - 125| ≥ 0.25 should be removed.
The absolute value inequality that represents the lengths of all the cases
that should removed is therefore;
|x - 125| ≥ 0.25Learn more here:

Circle A has a circumference of 2 2/3m. Circle B has a diameter that is 1 1/2 times as long as Circle As diameter. What is the circumference of Circle B?
Answers
Step-by-step explanation:
the circumference of a circle is
c = 2×pi×r
with r being the radius.
the diameter of a circle is always twice its radius.
circle A
2 2/3 = 8/3 = 2×pi×r
4/3 = pi×r
r = 4/3 / pi = 4/(3×pi) = 0.424413182... m
the diameter is then : 0.848826363... m
the diameter of B is 1.5 times the diameter of A :
1.273239545... m
therefore, the radius of B is 0.636619772... m
and so, the circumference of B is
2×pi×0.636619772... = 4 m
of course, if we had considered that both diameter and circumference are in linear dependence (see the formula for the circumference), we could get the result much faster. if the diameter increases 1.5 times, then also the circumference increases 1.5 times :
2 2/3 = 8/3 × 1.5 = 8/3 × 3/2 = (8×3)/(3×2) = 8/2 = 4 m

Tia received $7.55 in change in quarters and dimes. There
were 38 coins in all. How many of each kind did she
receive?
Answers
Answer: 25 quarters and 13 dimes
Step 1: Setup Coin Value and Coin Total Equation:
Coin Value Equation → 0.1d + 0.25q = $7.55 where d = dimes and q = quarters
Coin Total Equation → d + q = 38
Step 2: Rearrange Coin Total Equation in terms of dimes (d)
d = 38 - q ← Revised Coin Total Equation
Step 3: Plug in our Revised Coin Total Equation for d into our Coin Value Equation:
0.1(38 - q) + 0.25q = $7.55
0.1(38) - 0.1(q) + 0.25q = $7.55
3.8 - 0.1q + 0.25q = $7.55
3.8 + (0.25 - 0.1)q = $7.55
3.8 + 0.15q = $7.55
Step 4: Subtract 3.8 from each side of the equation to isolate q
3.8 - 3.8 + 0.15q = $7.55 - 3.8
0.15q = 3.75
Step 5: Divide each side of the equation by 0.15 to isolate q
0.15q/0.15 = 3.75 /0.15
q = 25
Step 6: Using our value for q, Solve for d using our Coin Total Equation:
d + 25 = 38
Subtracting 25 from both sides, we get d + 25 - 25 = 38 - 25
d = 13
Summarizing our word problem, we see that 25 quarters and 13 dimes add up to $7.55

Answer:

Step-by-step explanation:
The equation is in vertex form, so you can tell that the vertex of the graph is (x, y) = (-4, -8). This suggests your table should have values that are symmetrical about x = -4. The attachment shows one possible table of values.
__
It is generally convenient to let a graphing calculator or spreadsheet compute a table of values for you.
Put each chosen value of x into the equation and do the arithmetic.
For x=-5, ...
y = 3(-5+4)² -8 = 3(-1)² -8 = 3 -8 = -5
Then (-5, -5) will be a point in your table. Recognizing the symmetry of the function, you know that (-3, -5) will also be a point in your table.

She collected the responses and calculated that the proportion for her university was 43%. Which one of the following statements about the z-test is correct?
It is not safe to use the z-test for p, since the sample is not a random sample from the entire population (or cannot be considered as one).
