Answer 1

Find the volume of the sphere. Round your answer to the nearest tenth. Use 3.14 for n. A sphere has a diameter of 5.2 centimeters. The volume of the sphere is about cm?.​

we know that

the volume of the sphere is equal to

[tex]V=\frac{4}{3}\cdot\pi\cdot r^3[/tex]

In this problem we have

r=5.2/2=2.6 cm -----> the radius is half the diameter

pi=3.14

substitute the given values

[tex]\begin{gathered} V=\frac{4}{3}\cdot3.14\cdot2.6^3 \\ V=73.6\text{ cm\textasciicircum{}3} \end{gathered}[/tex]answer is 73.6 cubic centimeters

Jim's parents paid for the first three years of his college costs. When
he was a college senior, he was approved for an unsubsidized loan in the
amount of $15,200 at a 4.29% interest rate for 10 years.
a. If he chooses to make interest-only payments until the monthly loan
payments are due, for how long will he be making interest only
payments?

Answers

Jim can make interest-only payments until after 1 year and 6 months.

What is the interest-only payment?

The interest-only payment enables students to avoid interest capitalization during their school years and during the next six months after graduation.

The six-month period is called the grace period.

Non-capitalization of interest lowers the monthly repayments when payments become due after the grace period.

Amount of student loan = $15,200

Interest rate = 4.29%

Loan period = 10 years

Interest-only period = 1 year and 6 months

Amount of interest per month = $54.34 ($15,200 x 4.29% x 1/12)

Total interest during the interest-only period = $978.12 ($54.34 x 18)

Thus, the interest-only payments last for 18 months.

x+12% of x= 3.36 help

Answers

Answer:

x = 3

Step-by-step explanation:

x + .12x = 3.36  Combine like terms

1.12x = 3.36  Divide both sides of the equation by 1.12

x = 3

Answer:   x = 3

=======================================

Work Shown:

12% = 12/100 = 0.12

x + 12% of x = x + 0.12x = 1.12x = 3.36

1.12x = 3.36

x = 3.36/1.12

x = 3

---------------

Check:

12% of 3 = 0.12*3 = 0.36

x + 12% of x = 3 + 12% of 3 = 3 + 0.36 = 3.36

Or you could say 1.12x = 1.12*3 = 3.36

The answer is confirmed.

how could you use a graph of a proportional relationship to find any ratio in the the proportional relationship why does this work?

Answers

When the graph of a relationship shows a line that passes through the origin, then it is proportional.

How to illustrate the information?

If a connection's graph is a line that runs through its origin, it is proportional. If there isn't a line or ray that does this, the ratio isn't proportional. The equation for the proportionality constant is K = y/x.The equation that describes the slope of a straight line in relation to its origin is identical to this one.

When the graph of a proportional connection passes through the origin, any ratio in the proportional relationship can be found.

A relationship is proportional if its graph is a line or ray that passes through the origin. It is not proportional if the line or ray does not go through the origin.

The angle of elevation to the top of a building changes from 15​° to ​30° as an observer advances 140 feet toward the building. Find the height of the​ building, x, to the nearest foot.
pls explain

Answers

Answer:

70 ft

Step-by-step explanation:

To find the height of the building, we can use the trigonometric relationship between the angle of elevation, the distance from the object, and the height of the object.

In this case, we have a right triangle formed by the observer, the top of the building, and the base of the building. Therefore, we can use the tangent trigonometric ratio, since the height of the building is the opposite the angle of elevation, and the distance between the observer and the building is the side adjacent the angle.

[tex]\boxed{\begin{minipage}{7 cm}\underline{Tangent trigonometric ratio} \\\\$\sf \tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle.\\\end{minipage}}[/tex]

Let "x" be the height of the building.

Let "d" be the initial distance from the observer to the building.

The angle of elevation changes from 15° to 30° as the observer advances 140 feet toward the building.

(See the attachment for a visual representation).

Based on this information, we can set up the following equations:

[tex]\tan 15^{\circ}=\dfrac{x}{d}[/tex]

[tex]\tan 30^{\circ}=\dfrac{x}{d-140}[/tex]

Rearrange both equations to isolate d:

[tex]d=\dfrac{x}{\tan 15^{\circ}}[/tex]

[tex]d=\dfrac{x}{\tan 30^{\circ}}+140[/tex]

Solve this system of equations by the method of substitution.

[tex]\dfrac{x}{\tan 15^{\circ}}=\dfrac{x}{\tan 30^{\circ}}+140[/tex]

[tex]\dfrac{x}{\tan 15^{\circ}}-\dfrac{x}{\tan 30^{\circ}}=140[/tex]

[tex]\dfrac{x\tan 30^{\circ}-x \tan 15^{\circ}}{\tan 30^{\circ}\tan 15^{\circ}}=140[/tex]

[tex]\dfrac{x(\tan 30^{\circ}- \tan 15^{\circ})}{\tan 30^{\circ}\tan 15^{\circ}}=140[/tex]

[tex]x=\dfrac{140\tan 30^{\circ}\tan 15^{\circ}}{\tan 30^{\circ}- \tan 15^{\circ}}[/tex]

[tex]x=\dfrac{140\cdot \frac{\sqrt{3}}{3}(2-\sqrt{3})}{\frac{\sqrt{3}}{3}- (2-\sqrt{3})}[/tex]

[tex]x=\dfrac{\dfrac{140(2\sqrt{3}-3)}{3}}{\dfrac{4\sqrt{3}-6}{3}}[/tex]

[tex]x=\dfrac{140(2\sqrt{3}-3)}{2(2\sqrt{3}-3)}[/tex]

[tex]x=\dfrac{140}{2}[/tex]

[tex]x=70[/tex]

After solving the equation the value of x is 13/5.

What are equations?A mathematical equation is a formula that uses the equals sign to express the equality of two expressions. As in 3x + 5 = 15, for instance. Equations come in a variety of forms, including linear, quadratic, cubic, and others. The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.

So, we can see that both triangles are congruent under the SAS condition.

△ABC ≅ △ADEAB ≅ AD (Given)AC ≅ AE (Given)∠A = ∠A (Common angle)

Since both triangles are congruent, then we can conclude that side BC will be congruent to side DE under CPCT (Corresponding parts of congruent triangles).

Then, we can form the equation:

5x - 2 = 11

Now, solve the equation as follows:

5x - 2 = 115x = 11 + 25x = 13x = 13/5

Therefore, after solving the equation the value of x is 13/5.

So, the formula of the Pythagorean Theorem:

c² = a² + b²

Where a (AC) = 4 and b (CB) = 3 as the given figure is symmetric and so line CB will be equal to 3.

The distance between the point (-1,0) and (7,6) is 10.

Distance between the points:

Distance between two points is the length of the line segment that connects the two points in a plane.

d=√((x2 – x1)² + (y2 – y1)²).

Given,

(−1,0) and (7,6).

Here we need to find the distance between these points.

Apply the values on the formula , in order to solve it,

d = √(7 - (-1))² + (6 - 0)²

When we simplify it, then we get,

d = √(7 + 1)² + (6)²

d = √(8)² + 36

d = √64 + 36

Answers

96622 is the total number of employees in the company.

Let x be the total number of employees in the company

we are given that, 28600 employees comprise 29.6% of the company's total employees

Thus,

x * 29.6% = 28600

x * 296/1000 = 28600

x * 296 = 28600 * 1000

x * 296 =28600000

x = 28600000/296

[ where, h1, h2, h3... hn represents roots of that polynomial, and " a " is the stretch of curve]

And by that, we can sort out the roots of given polynomial that are :

x = -3, -2, 1 and 2

Since there are four roots, the least degree polynomial formed will have bi - quadratic polynomial.

And it will be represented as :

Mike decided to rent an airpod from from applerental.com. The website advertised an Airpod rental of $5 a week with a down payment of $10.

How much is the total cost if Mike rented the Airpod for 6 months? (hint: there are 4 weeks in a month)

Answers

If the website advertised an Airpod rental of $5 a week with a down payment of $10, then the total cost he paid if he rented the Airpod for 6 months is $130

The amount he paid for down payment = $10

The rent amount for the airpod for one week = $5

We know,

There are 4 weeks in a month

Number of weeks in 6 month = 6×4

= 24 weeks

The total amount her paid for if he rented the airpod for 6 months = The amount he paid for down payment + (The rent amount for the airpod for one week ×24)

= 10+5×24

= 10+120

= $130

create 2 equations.

x+y = 380

2.50x+5.80y = 1544

solve for x in the first equation and plug into the second equation.

x = 380-y

2.50(380-y) +5.80y = 1544

distribute and simplify.

950 + 3.3y = 1544

simplify

3.3y = 594

y = 180

plug y back into first equation and you get that there were 200 children.
