Answer:

75ft long 60 ft wide

Step-by-step explanation:

one inch is 5 feet so for every foot you would x 5

15x5=75

12x5=60

The actual dimensions of Jamal's property are 75 feet long and 60 feet wide.

If Jamal's scale drawing is 15 inches long and 12 inches wide, and one inch on the drawing represents 5 feet in real life, we can calculate the actual dimensions of the property.

Length of the property:

15 inches on the drawing represents 15 * 5 = 75 feet in real life.

Width of the property:

12 inches on the drawing represents 12 * 5 = 60 feet in real life.

Therefore, the actual dimensions of Jamal's property are 75 feet long and 60 feet wide.

The measure of the angle R in the right-angle triangle will be 22.62°.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

The measure of the angle R is given by the sine rule. The sine of angle R is the ratio of the perpendicular to the hypotenuse. Then we have

sin R = 5 / 13

R = sin⁻¹(5/13)

R = 22.62°

The measure of the angle R in the right-angle triangle will be 22.62°.

The measure of angle R is 30 degrees.

To determine the measure of angle R, we can use the properties of special right triangles, specifically the 30-60-90 right triangle. In such a triangle, the angles are 30 degrees, 60 degrees, and 90 degrees, and the lengths of the sides opposite these angles are in the ratio 1:√3:2, respectively.

Given that side PR is the hypotenuse of the right triangle PQR and it is 2 units long, we can deduce that triangle PQR is a 30-60-90 triangle. The side QR, which is opposite the 30-degree angle at Q, is half the length of the hypotenuse. Since PR is 2 units, QR must be 1 unit.

The side PQ is opposite the 60-degree angle at P and is 3 times the length of QR. Since QR is 1 unit, PQ must be 3 units.

The angle R is opposite the side PQ, and since we have established that PQR is a 30-60-90 triangle, angle R must be the smallest angle, which is 30 degrees.

Therefore, the measure of angle R is 30 degrees.

Answer:

The length of each side of the cube is [tex]\frac{1}{8}\ m[/tex]

Step-by-step explanation:

we know that

The volume of a cube is equal to

[tex]V=LWH[/tex]

but remember that in a cube

Length, width and height have the same value

so

Let

b-----> the length side of the cube

[tex]L=W=H=b[/tex]

substitute in the formula

[tex]V=(b)(b)(b)=b^{3}[/tex]

In this problem we have

[tex]V=\frac{1}{512}\ m^{3}[/tex]

substitute and solve for b

[tex]b^{3}=\frac{1}{512}[/tex]

[tex]b=\sqrt[3]{\frac{1}{512}}\\ \\b=\frac{1}{8}\ m[/tex]

therefore

The length of each side of the cube is [tex]\frac{1}{8}\ m[/tex]

Answer:

[tex]\cos(\alpha +\beta)=\frac{2}{3}(1-\frac{\sqrt{5}}{5})[/tex]

Step-by-step explanation:

Let the hypotenuse of the smaller triangle be h units.

Then; from the Pythagoras Theorem.

[tex]h^2=4^2+2^2[/tex]

[tex]h^2=16+4[/tex]

[tex]h^2=20[/tex]

[tex]h=\sqrt{20}[/tex]

[tex]h=2\sqrt{5}[/tex]

From the smaller triangle;

[tex]\cos (\alpha)=\frac{4}{2\sqrt{5} }=\frac{2}{\sqrt{5} }[/tex] and [tex]\sin(\alpha)=\frac{2}{2\sqrt{5} }=\frac{1}{\sqrt{5} }[/tex]

From the second triangle, let the other other shorter leg of the second triangle be s units.

Then;

[tex]s^2+4^2=6^2[/tex]

[tex]s^2+16=36[/tex]

[tex]s^2=36-16[/tex]

[tex]s^2=20[/tex]

[tex]s=\sqrt{20}[/tex]

[tex]s=2\sqrt{5}[/tex]

[tex]\cos(\beta)=\frac{2\sqrt{5} }{6}=\frac{\sqrt{5} }{3}[/tex]

and

[tex]\sin(\beta)=\frac{4}{6}=\frac{2}{3}[/tex]

We now use the double angle property;

[tex]\cos(\alpha +\beta)=\cos(\alpha)\cos(\beta) -\sin(\alpha)\sin(\beta)[/tex]

we plug in the values to obtain;

[tex]\cos(\alpha +\beta)=\frac{2}{\sqrt{5} }\times \frac{\sqrt{5} }{3}-\frac{1}{\sqrt{5} }\times \frac{2}{3}[/tex]

[tex]\cos(\alpha +\beta)=\frac{2}{3}(1-\frac{\sqrt{5}}{5})[/tex]

Answer:

[tex]cos(\alpha + \beta)=cos(68.4\°) \approx 0.37[/tex]

Step-by-step explanation:

We know both legs, we can use the tangent trigonometric reason to find the angle.

[tex]tan\alpha =\frac{2}{4}\\ tan \alpha=\frac{1}{2}\\ \alpha=tan^{-1}(\frac{1}{2} )\\ \alpha \approx 26.6\°[/tex]

We know the hypothenuse and the opposite leg. We can use the sin trigonometric reason to find the angle

[tex]sin\beta =\frac{4}{6}\\ sin\beta=\frac{2}{3}\\ \beta=sin^{-1} (\frac{2}{3} )\\\beta= 41.8\°[/tex]

So, the sum of them is

[tex]\alpha + \beta = 26.6+41.8= 68.4\°[/tex]

Then,

[tex]cos(\alpha + \beta)=cos(68.4\°) \approx 0.37[/tex]

Therefore,

[tex]cos(\alpha + \beta)=cos(68.4\°) \approx 0.37[/tex]

Answer:

(3700)(1+.059/12)^4(1+.172/12)^8 is the corect answer -Apex

Step-by-step explanation:

Answer:

Option C is correct.

Step-by-step explanation:

Felipe transferred a balance of $3700 to a new credit.

The card had an introductory offer of 5.9% APR for the first 4 months and after that 17.2 % APR.

The card compounds interest monthly, that gives n = 12

So, the equation that represents Felipe's balance at the end of the year will be:

[tex]p(1+\frac{r}{n})^{a}\times (1+\frac{r}{n})^{b}[/tex]

Here a is the introductory rate number of months that is 4

And b is the rest of the standard months that is 8

So, the expression becomes:

Answer:

Step-by-step explanation:

Let x km/h be the speed of the current.

1. A tourist traveled on a motorboat against the current for 25 km (the current interfered), then it took him

[tex]\dfrac{25}{12-x}\ hours.[/tex]

2. Then he returned back on a raft (the speed of the current is the speed of the raft), then it took him

[tex]\dfrac{25}{x}\ hours.[/tex]

3. In the boat the tourist traveled for 10 hours less than on the raft, thus

[tex]\dfrac{25}{12-x}+10=\dfrac{25}{x}.[/tex]

Solve this equation:

[tex]25x+10x(12-x)=25(12-x),\\ \\25x+120x-10x^2=300-25x,\\ \\10x^2-170x+300=0,\\ \\x^2-17x+30=0,\\ \\D=(-17)^2-4\cdot 30=289-120=169,\\ \\x_{1,2}=\dfrac{-(-17)\pm\sqrt{169}}{2}=2,\ 15.[/tex]

The speed of the current cannot be greater than the speed of the boat, because then tourist was not able to travel against the current. Thus, the speed of the current is 2 km/h.

Answer:

The length is 65 cm and the width is 12 cm

Step-by-step explanation:

A = lw = 780

P = 2 (l+w) = 154

The length is 5 more than 5 times the width

l=5w+5

P = 2 (l+w) = 154

Divide each side by 2

2 /2 (l+w) = 154/2

l+w = 77

Substituting l = 5w+5

5w+5 +w = 77

6w+5 = 77

Subtract 5 from each side

6w +5-5 = 77-5

6w = 72

Divide each side by 6

6w/6 = 72/6

w = 12

Now lets find l

l = 5w+5

l = 5(12)+5

l = 60+5

l = 65

We could answer this either by checking each listed expression to see whether it is a factor of 9r^2-4r+1, or

We could take the coefficients of 9r^2-4r+1, determine the quantity b²-4ac (called the 'discriminant') and draw a conclusion based upon whether the discriminant is -, + or 0.

Let's use the 2nd approach.

Here, a = 9, b = -4 and c = 1.

Then the discriminant is b²2 - 4ac, or (-4)² - 4(9)(1), or 16 - 36.

Since 16 - 36 is negative, we conclude that this 9r^2 - 4r + 1 has NO REAL FACTORS.

Answer:

18/90 or you can say 18 over 90.

Step-by-step explanation:

So we have 18 out of the total of 90 photos.

So we know automatically the fraction is 18/90, we have 18 out of the rest of the 90 photos.  

The fraction of photos in the album that are black and white is calculated by dividing the number of black and white photos (18) by the total number of photos (90) which results in a fraction of 0.2 or 1/5.

To find what fraction of the photos are black and white, you'll start by considering all of the photos in the album. This is your total and it's 90 photos. Then, focus on the specific type of photos you're interested in, which are the black and white ones. There are 18 black and white photos. So to find the fraction of photos that are black and white, you would divide the number of black and white photos (18) by the total number of photos (90). This calculation would look something like this: 18 ÷ 90 = 0.2

So, the fraction of black-and-white photographs is 0.2 or, expressed as a common fraction, 1/5. This means that out of every 5 photos in the album, 1 of them is black and white.
