The perimeter of a rectangular garden is 64 centimeters. The length of the garden is three times the width. Find the length
and the width

Answer:

Step-by-step explanation:

Let f and s represent the amounts invested in the fund and in stocks, respectively. The problem statement gives rise to two equations:

  f + s = 15000 . . . . . . . Susan invested a total of 15000

  0.11f + (-0.05)s = 850 . . . . . her total return was 850

These can be solved by any of a variety of methods. Using elimination, we can multiply the second equation by 20 and add it to the first:

  20(0.11f -0.05s) +(f + s) = 20(850) +15000

  3.2f = 32000 . . . . . . . . . simplify

  f = 10000

  s = 15000 -f = 5000

Susan invested $10,000 in the fund and $5,000 in stock.

Choice A

Step-by-step explanation:

From the right-angled triangle we have been given the following;

One angle - 33 degrees

The hypotenuse - 13 units

We are required to determine the length of the side, opposite the angle, marked x.

Using the Mnemonic; SOHCAHTOA

The sine of an angle is; (opposite side)/(hypotenuse)

Therefore;

sin 33 = x/13

x = 13 * sin 33

1. 10 in. to millimeters: 254.00 mm

2. 60 ft. to meters: 18.29 m

3. 4.5 in. to millimeters: 114.30 mm

4. 12 U.S. quarts to liters: 11.36 L

5. 25 feet per second to meters per second: 7.62 m/s

6. 100 miles to kilometers: 160.93 km

To convert inches to millimeters, we use the conversion factor 1 inch = 25.4 millimeters. Therefore, for 10 inches, the calculation is: [tex]\(10 \, in. \times 25.4 \, \frac{mm}{in.} = 254.00 \, mm.\)[/tex]

For the conversion from feet to meters, the conversion factor is 1 foot = 0.3048 meters. Thus, for 60 feet, the calculation is: [tex]\(60 \, ft. \times 0.3048 \, \frac{m}{ft.} = 18.29 \, m.\)[/tex]

Converting inches to millimeters again, using the same conversion factor, we get [tex]\(4.5 \, in. \times 25.4 \, \frac{mm}{in.} = 114.30 \, mm.\)[/tex]

Moving on to quarts to liters, 1 U.S. quart is approximately 0.94635 liters. For 12 quarts, the conversion is [tex]\(12 \, qts \times 0.94635 \, \frac{L}{qt} = 11.36 \, L.\)[/tex]

For the speed conversion from feet per second to meters per second, we use the conversion factor 1 ft/s = 0.3048 m/s. Thus,[tex]\(25 \, ft/s \times 0.3048 \, \frac{m}{ft} = 7.62 \, m/s.\)[/tex]

Finally, for miles to kilometers, the conversion factor is 1 mile = 1.60934 kilometers. Hence, [tex]\(100 \, miles \times 1.60934 \, \frac{km}{mile} = 160.93 \, km.\)[/tex]

Step-by-step explanation:

If we use 3.14 as pi, the areas of these circles are 415.265 square units (I recommend rounding up to 415.27 unless it says otherwise).

Step-by-step explanation:

To find the area of a circle, square the radius and multiply it by pi. To find the radius, we divide the diameter by 2 to get 11.5. Then, square 11.5 to get 132.25 and multiply by pi, or 3.14, to get 415.265, rounding up to 415.27 square units.

Answer:

AC = 18.1 cm

Step-by-step explanation:

Construct a line from point B perpendicular to the line AD and mark it as E on line AD. Now you have a right triangle ABE with AB = 16 cm and AE = AD - BC

so AE = 11 cm - 4 cm = 7 cm

You can find BE by using Pythagorean theorem

BE^2 = AB^2 - AE^2

BE^2 = 16^2 - 7^2

BE^2 = 256 - 49

BE^2 = 207

BE = 14.4 cm

Draw a line from A to C, you have a right triangle ACD with AD = 11cm and CD = BE = 14.4 cm

Using Pythagorean theorem

AC^2 = AD^2 + CD^2

AC^2 = 11^2 + 207

AC^2  = 121 + 207

AC^2 =  328

AC = 18.1 cm

Arc PR measures 90 degrees because it is a minor arc that intercepts central angle PQR, which measures 90 degrees.

The measure of arc PR is 90 degrees. This can be determined from the given diagram, which shows a circle with arc PR labeled. We also know that central angle PQR measures 90 degrees.

Minor arcs are arcs that intercept central angles less than 180 degrees. Major arcs are arcs that intercept central angles greater than or equal to 180 degrees.

Since arc PR intercepts central angle PQR, which measures 90 degrees, arc PR must be a minor arc. Minor arcs have the same measure as their central angles, so arc PR must also measure 90 degrees.

Here is an alternative way to think about it:

The entire circle can be divided into 360 degrees.

Arc PR is a portion of the circle, so it must have some measure.

Central angle PQR also divides the circle into two portions.

Since arc PR intercepts central angle PQR, it must have the same measure as central angle PQR, which is 90 degrees.

Therefore, the measure of arc PR is 90 degrees.

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

There are 5 total 6-packs of cola. 1 is cherry and the other is vanilla. 2 out of 5 are the flavors. This means you have a 2 in 5 chance of getting a cherry or vanilla cola.

Final answer:

The probability of randomly choosing a cherry cola or vanilla cola from all the cans available is 2/5, since there are 12 such cans out of a total of 30 cans.

Explanation:

To find the probability that a can of cola chosen at random will be either cherry cola or vanilla cola, we first need to count the total number of cans and then count the number of cherry and vanilla cola cans.

There are 2 six-packs of regular cola, which amounts to 12 cans. There is 1 six-pack each of diet cola, cherry cola, and vanilla cola, which adds up to 6 + 6 + 6 = 18 cans. In total, there are 12 + 18 = 30 cans of cola.

Out of these, there are 6 cans of cherry cola and 6 cans of vanilla cola, totalling 12 cans. Thus, the probability of choosing a cherry or vanilla cola is the number of cherry and vanilla cans divided by the total number of cans, which is 12/30.

When we simplify 12/30, we get 2/5. Therefore, the correct answer is B. 2/5.

Answer:

232 ft above sea level

Step-by-step explanation:

He started at -49 ft and then he was later 281 ft higher than that... so just do -49+281 or 281-49= 232

Reymonte started his hike 49 feet below sea level, or at an elevation of -49 feet. He then hiked up 281 feet. By adding these two numbers together, we find that Reymonte ended his hike at an elevation of 232 feet above sea level.

The subject of this question is Mathematics, and it's specifically related to the topic of integers. In the context of this question, elevation is used to indicate height relative to sea level, with negative indicating below sea level and positive above. Reymonte started at an elevation of -49 feet, or 49 feet below sea level. He then hiked up 281 feet.

To find his final elevation relative to sea level, we add the increase in elevation to his initial elevation. So, we add 281 feet to -49 feet:

-49 feet + 281 feet = 232 feet

So at the end of the hike, Reymonte was at an elevation of 232 feet above sea level.

Answer:

540 degrees

Step-by-step explanation:

We can find the sum of the interior angles by using the formula (n - 2) * 180.

n: represents the total number of angles in the polygon

We can determine that polygon contains 5 angles, which means you would substitute the n variable with. Then you would simply follow the order of operation (ex: parentheses first, multiplication next, etc.) to find our answer.

(5 - 2) * 180

Solve the contents inside the parentheses first, as mentioned above.

(5 - 2) * 180

(5 - 2) = 3

So, we are left with

3 * 180

Now you'd multiply 3 * 180 and the product of that represents the sum of the measures of the interior angles of the polygon.

3 * 180 = 540

In conclusion, the sum of the measures of the interior angles is 540 degrees.

No Real roots to this Quadratic Equation

Step-by-step explanation:

Our Quadratic equation is given as

[tex]x^2+5x+7=0[/tex]

In order to find that do we have the real roots of a quadratic equation , the Discriminant must be greater or equal to 0. The Discriminant is denoted by D and given by the formula

[tex]D= b^2-4ac[/tex]

Where b is the coefficient of the middle term containing x, a is the coefficient of the term containing [tex]x^{2}[/tex] and the c is the constant term.

Hence we have

a = 1 , b = 5 and c = 7

Calculate D

[tex]D=b^2-4ac\\D=5^2-4*1*7\\D=25-28\\D=-3[/tex]

Hence we see that the Discriminant (D) is less than 0, our answer is no real roots to this quadratic equation.
