Final answer:

The expression for the greater number is a + 8, which is found by adding the given difference of 8 to the lesser number a.

Explanation:

The student has given us an equation to work with: The difference between two numbers is 8, and the lesser number is known as a. To find the expression for the greater number, we simply need to add the difference to the lesser number. Therefore, the greater number can be expressed as a + 8.

Let's illustrate this with an example. If the lesser number, a, is 5, then to find the greater number, we add the difference of 8 to 5, giving us 13 as the greater number.

Square root helps to find the factor of a number which when multiplied by itself gives us the number. The value of √1.69 is √1.3.

Square root can be defined as the process of finding a number which is a factor of a number when multiplied by itself to get a number.

In order to evaluate the value of √1.69, we will convert decimal value 1.69 into a fraction, therefore, the fraction can be written as,

[tex]1.69 = \dfrac{169}{100}[/tex]

Now, using this equivalent value of 1.69, the evaluation can be written as,

[tex]\sqrt{1.69}\\\\= \sqrt{\dfrac{169}{100}}[/tex]

Further, using the exponential property the value can be written as,

[tex]= \sqrt{\dfrac{169}{100}}\\\\\\={\dfrac{\sqrt{169}}{\sqrt{100}}}\\\\\\=\dfrac{13}{10}\\\\=1.3[/tex]

Hence, the value of √1.69 is √1.3.

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]

Given tanθ = 4/3 and sin θ =-4/5, based on the Pythagorean identity the cos θ is  3/5.

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.

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.

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.

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.

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.

Final answer:

The number 9.125 x 10¹⁰ in standard form is 91,250,000,000.

Explanation:

The number 9.125 x 10¹⁰ in standard form is written as 91,250,000,000.

The documentation "E10" addresses increasing the number by 10 raised to the force of 10. For this situation, "E10" signifies we really want to increase 9.125 by 10¹⁰.

To work out this, we move the decimal guide 10 spots toward the right, bringing about an extremely huge number:

9.125 E10 = 9,125,000,000

In this way, 9.125 E10 in standard structure is 9,125,000,000.

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°.
