3. Jared has two ropes. Each rope is 9 inches long. How many inches of rope does he have in all?

Answers

the answer is super easy all you have todo is to add nine plus nine and then you will get your answer to save time the answer is 19.

The length of one rope = 9 in

Number of ropes Jared have = 2.

The total inches of rope does Jared have will be calculated as under -

We can add the length of two ropes as = 9 in + 9 in = 18 in

Or we can do it by other method as well.

The other method is by multiplying -

The total inches of rope does Jared have = The length of one rope × Number of ropes Jared have

The total inches of rope does Jared have = 9 in × 2 ropes = 18 in

Find the lengths of the sides of the right triangle?

Answers

You can guess from your knowledge of Pythagorean triples that the triangle is a 5-12-13 right triangle. Since one side is 7 less than the other, this guess is confirmed.

The lengths of the sides are:
2x = 12
2x -7 = 5

_____
You can use the Pythagorean theorem to write the relationship between the sides.
(2x)² +(2x -7)² = 13²
4x² +4x² -28x +49 = 169 . . . . . eliminate parentheses

What is the area of the rhombus shown below? A. 110.5 square units B. 129.2 square units C. 221 square units D. 15 square units

Answers

the answer is A. 110.5

The area of the rhombus is 110.5 square units if the lengths of the diagonal of a rhombus are 13 and 17 units option (A) 110.5 square units is correct.

What is a rhombus?

A rhombus is a two-dimensional shape having four parallel opposite pairs of straight, equal sides. This shape resembles a diamond and is what you'd find on a deck of cards to represent the diamond suit. Rhombuses can be encountered in a variety of common situations.

We have a rhombus shown in the picture with dimensions:

As we know,

The area of the rhombus is given by:

A =pq/2

p and q are the lengths of the diagonal of a rhombus.

p = MK = 13 units

q = JL = 17 units

Plug the values in the formula:

A = (13×17)/2

A = 221/2

A = 110.5 square units

Thus, the area of the rhombus is 110.5 square units if the lengths of the diagonal of a rhombus are 13 and 17 units option (A) 110.5 square units is correct.

Valdez Construction signed a note with a payment of $5,200 per quarter for 5 years.
Find the amount they must set aside today to satisfy this capital requirement in an account earning 8% compounded quarterly.

$30,506.32

$126,346.32

$51,054.38

$85,027.44

Answers

If P = Periodic payments done quarterly (that is, four time in a year) = $5,200, n = number of years (5), R = Annual interest rate = 8% = 0.08, and A = Amount to be set aside today, then

A = P [1-(1+R/4)^4n]/(R/4) = 5200 [1-(1+0.08/4)^4*5]/(0.08/4) = $85,027.45

Therefore, Valdez construction should set aside $85,027.44 now to satisfy the capital requirement.

Two friends bring hamburger meat to your cookout. One brings 2.7 pounds, and the other brings 3.54 pounds. How much hamburger meat do they bring?

Answers

Answer:
They bought 6.24 pounds of hamburger meat

Explanation:
We are given that:
The first friend brought 2.7 pounds of hamburger meat
The second friend brought 3.54 pounds of hamburger meat

The total amount of hamburger meat they both brought would be simply the summation of what they brought individually.

This means that:
Total amount brought = 2.7 + 3.54
Total amount brought = 6.24 pounds of hamburger meat

Find an equation of the line passing through the pair of points. Write the equation in the form Ax+ By=C. (3,2) and (5,8)

Answers

The equation of the line passing through points (3,2) and (5,8) in the form of Ax+By=C will be written as follows:
equation of the line is given by the formula:
a(x-x1)=y-y1
where a is the slope
a=(y-y1)/(x-x1)
thus using our values:
a=(8-2)/(5-3)=6/2=3
thus the equation of the line will be:
3(x-3)=y-2
simplifying the above and writing in the form of Ax+By=C we shall have:
3x-9=y-2
3x-y=-2+9
3x-y=7
thus 3x-y=7 is in the form of Ax+By=C where A=3, B=-1 and C=7

You earn $56 for washing 8 cars. How much do you earn for washing 5 cars?

Answers

You earn $56 for washing 8 cars.

First find out how much you earn washing one car. Divide 56 with 8

56/8 = 7

You earn $7 for washing 1 car.

Now find out how much you earn washing 5 cars.

7/1 (being $7 per 1 car)
5/5 (amount of cars washed)

7/1 x 5/5 = 35/5

For 5 cars, you earn $35.

$35 is your answer

hope this helps

Hello there!

$56 = 8 cars
$x = 5 cars

Now we can do cross multiply

8 * x = 5 * 56

8x = 280

Now we can divide both sides by 8

8x/8 = 280/8

x = 35

Thus,

You earned $35 for washing 5 cars!

the square in this figure has a side length of 14 inches. the radius of the quarter circle is 7 inches. what is the estimate area

Answers

The area of the shaded region is 42.14 square inches.

How the area of the shaded region is determined:

We are given a square with side lengths of 14 inches, and each corner of the square has a quarter circle with a radius of 7 inches. We need to find the area of the shaded region, which is the area of the square minus the area of the quarter circles.

To calculate the area of the figure, we need to consider both the square and the quarter circles.

1. Calculate the area of the square:

The square has a side length of 14 inches.

Area of the square = [tex]side^2[/tex] = [tex]14^2[/tex] = 196 square inches

2. Calculate the area of the quarter circles:

The quarter circle has a radius of 7 inches.

The area of a full circle is given by:

Area of the circle = [tex]\pi r^2[/tex]

Area of the quarter circle = 4/4 x [tex]\pi r^2[/tex]

= 1 x 3.14 x [tex]7^2[/tex]

= 153.86 square inches

Therefore, the area of the shaded region = Area of the square - Area of the quarter circles:

= 196 - 153.86

= 42.14 square inches

Complete Question:

The square in the figure has a side length of 14 inches. The radius of the each quarter circle is 7 inches. What is the area of the shaded region?

Given that tan^2 e= 3/8 what is the value of sec e? A. +√8/3 B.+ √11/8 C. 11/8 D. 8/3

Answers

ANSWER

[tex]{ \sec}(e) = \pm \: \sqrt{\frac{11}{8} } [/tex]

EXPLANATION

We use the Pythagorean Identity,

[tex] { \sec}^{2} (e) = 1 + { \tan}^{2} (e)[/tex]

It was given that,

[tex] { \tan}^{2} (e) = \frac{3}{8} [/tex]

We substitute the values into the identity to obtain,

[tex] { \sec}^{2} (e) = 1 + \frac{3}{8} [/tex]

[tex]{ \sec}^{2} (e) = \frac{11}{8} [/tex]

We take square root of both sides to get,

[tex]{ \sec}(e) = \pm \: \sqrt{\frac{11}{8} } [/tex]

Answer:

sec e = √(11/8) ⇒ answer B

Step-by-step explanation:

* Lets revise some identities in trigonometry

# sin²x + cos²x = 1

- Divide both sides by cos²x

∴ sin²x/cos²x + cos²x/cos²x = 1/cos²x

∵ sinx/cosx = tanx

∴ sin²x/cos²x = tan²x

∵ cos²x/cos²x = 1

∵ 1/cosx = secx

∴ 1/cos²x = sec²x

* Now lets write the new identity

# tan²x + 1 = sec²x

- Let x = e

∴ tan²e + 1 = sec²e

- Substitute the value of tan²e in the identity

∵ tan²e = 3/8

∴ 3/8 + 1 = sec²e

- Change the 1 to the fraction 8/8

∴ 3/8 + 8/8 = sec²e ⇒ add the fractions

∴ 11/8 = sec²e

- Take square root for the two sides to find sec e

∴ sec e = √(11/8)

∴ The answer is B

At 0°C, the volume of a gas is 22 liters. For each degree the temperature T (in degrees Celsius) increases, the volume V (in liters) of the gas increases by 225. Write an equation that represents the volume of the gas in terms of the temperature.

Answers

At [tex]T=0^{\circ}C[/tex], the volume of the gas is V=22 L.

At temperature [tex]T=1C[/tex], the volume of the gas is (22+225) L.

This means that if we increase the temperature by [tex]k[/tex] degrees:
[tex]T=k^{\circ}C[/tex]
the volume of the gas is
[tex]V=22 + 225 k [L][/tex] (1)

Since T=k, we can rewrite eq.(1) as
[tex]V= 22 + 225 T [L][/tex]
which gives the expression for the volume of the gas in liters, as a function of the temperature T in Celsius.

Answer:

V=2/25T+22

after 2 hours, there are 18 mg of medicine left

Answer:

[tex]A=50(0.6)^x[/tex]

18 mg of medicine will be left in the patient's system after two hours.

Step-by-step explanation:

Given,

The initial quantity of the medicine, P = 50 mg,

Also, it decreases every hour at a constant rate of 40%

That is, r = 40 %,

Thus, the quantity of the medicine after x hours,

[tex]A=P(1-\frac{r}{100})^r[/tex]

[tex]=50(1-\frac{40}{100})^x[/tex]

[tex]=50(1-0.4)^x[/tex]

[tex]=50(0.6)^x[/tex]

Which is the required exponential decay function that models this scenario.

The quantity of the medicine after 2 hours,

[tex]A=50(0.6)^2=18\text{ mg}[/tex]
