Answer:
[tex]49a^2b^6[/tex]
Step-by-step explanation:
The given expression is:
[tex](7ab^3)^2[/tex]
Now, squaring the above expression, we get
=[tex](7)^2(a)^2(b^3)^2[/tex]
=[tex]49(a^2b^6)[/tex]
=[tex]49a^2b^6[/tex]
which is the required simplification of the given expression.
Thus, the correct simplification of the expression [tex](7ab^3)^2[/tex] is [tex]49a^2b^6[/tex].
Ye has his own business. He checks his sales receipts three times a day. One day, his afternoon sales eere $50 more than his morning sales, and his evening sales were three times his afternoon sales. If his total slaes for the day were $1,000, what were his evening sales?
Answer: Hence, his evening sales were $630.
Step-by-step explanation:
Let the sales in the morning be 'x'
Let the sales in afternoon be x+50
Let the sales in the evening be 3(x+50).
Total sales for the day = $1000
According to question, it becomes
[tex]x+x+50+3(x+50)=1000\\\\2x+50+3x+150=1000\\\\5x+200=1000\\\\5x=1000-200=800\\\\x=\dfrac{800}{5}\\\\x=160[/tex]
So, his evening sales would be
[tex]3(x+50)\\\\=3(160+50)\\\\=3\times 210\\\\=630[/tex]
Hence, his evening sales were $630.
Malik borrowed $8,000 to buy a new boat. He will pay off the loan after 4 years by paying back the principal plus 6.5% simple interest. How much will Malik pay back altogether?
A. $520 B. $2,080 C. $8,000 D. $10,080
Answer: D. $10,080
Step-by-step explanation:
The formula to find the simple interest is given by :-
[tex]S.I.=Prt[/tex], where P is principal amount , r is rate of interest ( in decimal ) and t is time period.
Given : Principal amount = $8,000
The rate of interest = 6.5% = 0.065
Time period= 4 years
Then , the simple interest will be :-
[tex]S.I.=8000\times0.065\times4=2080[/tex]
Hence, the amount which Malik pay back altogether = [tex]P+S.I.=8000+2080=\$10,080[/tex]

The perimeter of a rectangle is at most 80 inches. The length of the rectangle is 25 inches. The inequality 80-2w (is greater than or equal to) 50 , can be used to find w, the width of the rectangle in inches. Solve the inequality and interpret the solution.
How will the solution change if the width must be at least 10 inches and a whole number?
I know how to solve the equation, it is the second part I'm stumped on.
The width of the rectangle can be any number less than or equal to 15 inches. If the width also must be at least 10 inches and a whole number, then it can be any of the whole numbers between 10 and 15, inclusive.
Explanation:You're correct, the initial inequality does solve for w, the width of the rectangle. The inequality 80 - 2w ≥ 50 simplifies to 2w ≤ 30 and further simplified to w ≤ 15. This means that the width of the rectangle can be any number less than or equal to 15 inches.
For the second part of the question, if we also know that the width must be at least 10 inches and it must be a whole number, we can adjust the solution to be an integer number between 10 and 15, inclusive. So the possible values for width would be 10, 11, 12, 13, 14, or 15 inches in this case.

To solve the inequality 80 - 2w ≥ 50 for w, we need to isolate the variable w. If the width must be at least 10 inches and a whole number, then the solution changes.
Explanation:To solve the inequality 80 - 2w ≥ 50 for w, we need to isolate the variable w. We can do this by adding 2w to both sides of the inequality:
80 - 2w + 2w ≥ 50 + 2w
80 ≥ 50 + 2w
30 ≥ 2w
15 ≥ w
So, the width of the rectangle must be less than or equal to 15 inches.
If the width must be at least 10 inches and a whole number, then the solution changes. In this case, w can only take on whole number values from 10 to 15, inclusive. So, the width of the rectangle can be 10, 11, 12, 13, 14, or 15 inches.

The perpendicular bisector of side AB of ∆ABC intersects side AB at point D and BC at point E. If m∠CAB = 82° and m∠C = 68°, find m∠CAE.
Final answer:
The measure of ∠CAE is found by adding ∠CAB to half of ∠ABC. Since ∠ABC is 30° (calculated from the triangle angle sum), ∠ADE is 15°. Therefore, ∠CAE is 97°.
Explanation:
To find the measure of m∠CAE, let's use the information provided. Since DE is the perpendicular bisector of AB, we know that ∠ADE is a right angle (90°).
In ΔABC, the sum of the angles is 180°. We have m∠CAB = 82° and m∠C = 68°. To find m∠ABC, we subtract these from 180°:
180° - 82° - 68° = 30°
Since DE is the perpendicular bisector, ∠ADE is half of ∠ABC, thus:
∠ADE = 30° / 2 = 15°
Finally, we find m∠CAE by adding ∠CAB to ∠ADE:
m∠CAE = 82° + 15° = 97°
Final answer:
To find angle CAE, we use the properties of perpendicular bisectors and the given angles to determine that m∠CAE = 41°.
Explanation:
In triangle ABC, the perpendicular bisector of side AB intersects side AB at point D and side BC at point E. To find angle CAE, we need to use the properties of perpendicular bisectors and the given angles.
The perpendicular bisector of AB passes through the midpoint of AB, which is also equidistant from A and B. This means that CD is an angle bisector of angle CAB. Since the perpendicular bisector of AB is also perpendicular to AB, we have m∠CAD = m∠CAB/2 = 41°.
Since AC is a common side, triangles ACD and ACE share two congruent angles (m∠CAD and m∠CAE), making them similar. We can use the property of corresponding angles in similar triangles to find m∠CAE = m∠CAD = 41°.
Given the diagram, a supplement to ∠ABC could be:
∠BDC
∠DAB
∠ADC
∠BAC
Answer:
∠DAB
Step-by-step explanation:
A supplement to an angle is one that will sum to 180° with the given angle. ∠ABC is 110°; this means its supplement will be 180-110 = 70°.
The angle in the quadrilateral that is 70° is ∠DAB.

given tan theta =4/3 and sin theta =-4/5, find cos theta
Given tanθ = 4/3 and sin θ =-4/5, based on the Pythagorean identity the cos θ is 3/5.
How do we find the values of cos θ?The sine, cosine, and tangent of an angle are related by the Pythagorean identity sin²(θ) + cos²(θ) = 1.
This means we can solve for cosine given the sine value:
cos²(θ) = 1 - sin²(θ)
We know that sin(θ) = -4/5, so:
cos²θ) = 1 - (-4/5)²
cos²(θ) = 1 - 16/25
cos²(θ) = 9/25
Taking the square root of both sides,
we find that cos(θ) could be ±3/5.
However, we need to consider the quadrant in which theta is located. Since the tangent of theta is positive (4/3) and the sine of theta is negative (-4/5), theta must be in the fourth quadrant (where sine is negative and tangent is positive). In the fourth quadrant, cosine is positive.
Therefore, cos(theta) = 3/5.
