Answer:

C)  a = 10√3, b = 5√3, c = 15 , d = 5

Step-by-step explanation:

Here we use the ratio of 30, 60, 90 degree triangle.

The ratio of sides, 1:√3:2

2x = 10

x = 5

d = 5

b = 5√3

c = 5√3√3

c = 5*3 = 15

c = 15

a = 2(5√3)

a = 10√3

Therefore, a = 10√3, b = 5√3, c = 15 and d = 5

Answer:

The correct answer is C.

Step-by-step explanation:

From the [tex]60\degree[/tex] right angle triangle

[tex]\sin(60\degree)=\frac{b}{10}[/tex]

[tex]10\times \sin(60\degree)=b[/tex]

[tex]10\times \frac{\sqrt{3}}{2}=b[/tex]

[tex]5\sqrt{3}=b[/tex]

From the same [tex]60\degree[/tex] right angle triangle,

[tex]\cos(60\degree)=\frac{d}{10}[/tex]

[tex]10\times \cos(60\degree)=d[/tex]

[tex]10\times \frac{1}{2}=d[/tex]

[tex]5=d[/tex]

From the [tex]30\degree[/tex] right angle triangle

[tex]\sin(30\degree)=\frac{b}{a}[/tex]

[tex]\frac{1}{2}=\frac{5\sqrt{3}}{a}[/tex]

[tex]a=2\times 5\sqrt{3}[/tex]

[tex]a=10\sqrt{3}[/tex]

From the same [tex]30\degree[/tex] right angle triangle,

[tex]\cos(30\degree)=\frac{c}{a}[/tex]

[tex]\frac{\sqrt{3}}{2}=\frac{c}{10\sqrt{3}}[/tex]

[tex]10\sqrt{3} \times \frac{\sqrt{3}}{2}=c[/tex]

[tex]5 \times 3=c[/tex]

[tex]c=15[/tex]

the Answer would be 17.     Hope it helped ; )

Step-by-step explanation:

Answer: Correct answer is 1st option , 12.3

Step-by-step explanation:

We can find the value of x by calculating the tangent of the angle 39.

We know, that tangent of an angle in a triangle = Perpendicular/Base, corresponding to that angle.

So, tan 39 = 10/x

Again, we know that tan 39 = .81

So, .81 = 10/ x

or, x = 10/.81

or, x = 12.34

So value of x to the nearest tenth = 12.3

Option B is correct .i.e., 30 square centimeters

Step-by-step explanation:

We have to find area of ACDE.

From given figure ACDE is made up of two triangles ΔBCD &  ΔABE

So, Area of ACDE = Area of ΔBCD + Area of ΔABE

Area of traingle = [tex]\frac{1}{2}\times Base\times Height[/tex]

⇒ Area of ACDE =  [tex]\frac{1}{2}\times CD\times BF+\frac{1}{2}\times AB\times AE[/tex]

                            = [tex]\frac{1}{2}\times6\times2+\frac{1}{2}\times4\times12[/tex]

                            = [tex]6+2\times12[/tex]

                            = [tex]30\:cm^2[/tex]

Therefore, Option B is correct .i.e., 30 square centimeters

Answer:

l = (P -2w)/2

Step-by-step explanation:

When you're working any "solve for ..." problem, first you look to see where the variable of interest is and what is done to it.

If it is only found on one side of the equation, as here, then you're in luck. If it is only found in one term, as here, you have even better luck.

Identify all the terms on the side of the equation where the variable is located that do not contain the variable. Add their opposite to both sides of the equation. The result will be a term containing the variable, equated to a bunch of other stuff.

... P -2w = 2l . . . . . we added -2w to both sides of the equation

Now, we divide the equation by the coefficient of the variable.

... (P -2w)/2 = (2l)/2

... (P -2w)/2 = l . . . . . . simplify. This is the solution you're looking for

If you like, you can distribute the multiplication by (1/2) to get

... l = P/2 - w

a)7^-2=1/7^2=1/49

b) (8^4)^2/8^11=8^8/8^11=1/8^3=1/512.

To find the value of an expression without exponents, divide numbers and subtract the exponents for division, and when squaring, multiply the number by itself. Any number raised to the power of 2 is squared, and to the power of 3 is cubed.

To find the value of an expression without any exponents, you might need to use the rule: to divide two exponential numbers, divide the numbers out front and subtract the exponents. Here's an example:

If we have to find the value of 106 ÷ 103, you'll divide 10 by 10 (which is 1) and subtract the exponents (6 - 3), resulting in 103, which equals to 1000 when you remove the exponent.

In the context of squaring exponents, when you square a number like 52, it means 5 x 5, which equals 25. Squaring is also known as raising to the power of 2. Similar to this, any number raised to the power of 3 is said to be cubed.

These concepts are fundamental when calculating extreme values like $rac{4.81x10^4}{2.05x10^2}$, solving quadratics, and handling scientific notations.

Answer:

[tex]\frac{7}{10}[/tex]

Step-by-step explanation:

Carrie has 2 meters of ribbon. She cuts off pieces of ribbon that are 5/10 meter, 1/10 meter, and 7/10 meter

Lets add all the cut of pieces and subtract it from 2 meters

[tex]\frac{5}{10} +\frac{1}{10}+\frac{7}{10}=\frac{13}{10}[/tex]

Now we subtract 13/10 from 2 meters

[tex]2 - \frac{13}{10}[/tex]

To subtract , make the denominator same

[tex]\frac{2*10}{1*10} - \frac{13}{10}=\frac{20}{10} - \frac{13}{10}=\frac{7}{10}[/tex]

7/10 meter is the remaining piece of ribbon

After adding the lengths of the ribbon pieces Carrie cut (1.3 meters), the remaining ribbon length is calculated by subtracting this from the original length, leaving Carrie with 0.7 meters of ribbon.

Carrie starts with 2 meters of ribbon and cuts off pieces measuring 5/10 meter, 1/10 meter, and 7/10 meter. To find the length of the remaining ribbon, we need to add the lengths of the pieces she has cut and then subtract this total from the original length of the ribbon.

Therefore, the remaining piece of ribbon is 0.7 meters long.

r = -189

Step-by-step explanation:

-13 - 8 = r/9

- 21 = r/9

r = 9 * -21

r = -189

Answer:

r = -189

Step-by-step explanation:

-13= r/9 +8

To solve this equation, we will start by subtracting 8 from each side

These sorts of calculations are best done with a calculator that knows statistics.

a) The z-value of the limit ofv interest is (45,000 -35,551)/(5100) ≈ 1.8743. The empirical rule tells you between 16 and 2.5% of the distribution will lie above a limit that is between 1 and 2 standard deviations. So, our calculator value of 3% is approximately correct.

b) The standard deviation of the sample mean is reduced by a factor of √75 from that of the parent distribution for a sample size of 75. Then the z-value is ...

... (38,000 - 35,441)/(5100/√75) ≈ 2559/588.90 ≈ 4.345

Answer:

So, it is given to us that Jaden has 3 pound of beef in the first pot and 2 table spoons of chili powder.

(16 ounces = 1 pound)

(48 ounces = 3 pounds)

In he second bowl he uses the SAME amount of beef and 3 times as much chili powder.

Which means that he used 3 pounds of beef and 2*3 = 6 table spoons of chili powder in the second cup.

The question is asking you for the ratio between the two quantities in a cryptic manner.

so, it would end up being 3 pounds of beef every 6 table spoons of chili powder, which is nothing but Half (0.5 pounds of beef every tablespoon of chili powder).

1/2 pounds of beef every tablespoon of chili powder.

HOPE THIS HELPS!

Jaden used 0.5 pounds of beef for every tablespoon of chili powder in the second pot of chili when he tripled the amount of chili powder while keeping the amount of beef unchanged.

In the first pot of chili, Jaden effectively used 48 ounces of beef per 2 tablespoons of chili powder. This equates to 24 ounces of beef per tablespoon of chili powder. However, when Jaden tripled the amount of chili powder in the second pot, the ratio of beef to chili powder decreased since more chili powder is being used for the same amount of beef. Therefore, since he used three times as much chili powder in the second pot, this resulted in a ratio of 48 ounces of beef per 6 tablespoons of chili powder. That equates to 8 ounces of beef for every tablespoon of chili powder which are used in the second pot. Furthermore, since 1 pound equals 16 ounces, the number of pounds of beef used per tablespoon of chili powder in the second pot is 8/16, or 0.5 pounds.

I Say Answer Is 3.   X=5, Y=4

Step-by-step explanation:

A(x) = x(16 -x)

Area is the product of length and width. If the length is x, then the width will be half of the total perimeter less the two sides of length x, (32-2x)/2 = 16-x.

So, the area is ...

... A = length · width

... A(x) = x(16 -x)

_____

If you like, you can expand this to ...

... A(x) = -x² +16x

The area of a rectangular figure is calculated by multiplying the length and the width of the figure. So, the area as a function of x is: [tex]A(x) = x(16 - x)[/tex]

Given that:

[tex]P = 32[/tex] --- the perimeter of the fence

Represent

[tex]x \to[/tex] length

[tex]y \to[/tex] width

The perimeter of a rectangular fence is calculated as:

[tex]Perimeter = 2 \times (Length + Width)[/tex]

So, we have:

[tex]P= 2 \times (x+ y)[/tex]

[tex]32= 2 \times (x+ y)[/tex]

Divide both sides by 2

[tex]16= x+ y[/tex]

Make y the subject

[tex]y = 16 - x[/tex]

The area (A) of the fence is:

[tex]Area = Length \times Width[/tex]

So, we have:

[tex]A = x \times y[/tex]

Substitute [tex]y = 16 - x[/tex]

[tex]A = x \times (16 - x)[/tex]

[tex]A = x(16 - x)[/tex]

So, the area as a function of x is:

[tex]A(x) = x(16 - x)[/tex]

Explanation:

The question requires us to express the product of a decimal number and a power of ten in standard form. To find 35.6 times 10^-4 in standard form, we can use the rule of multiplying a decimal number by a power of ten. Multiplying by 10^-4 means we move the decimal point four places to the left.

So, 35.6 × 10^-4 becomes 0.00356. This is the number 35.6 shifted four decimal places to the left, as the exponent on the ten is negative, indicating division by ten for each unit of the exponent.
