I think that 3 rolls is wrong and that 6 rolls is right. If you create a 15 by 15 square and draw two lines through the center that connect to the opposite corner, you'll be able to use the Pythagorean Theorem.

Perimeter: 15+15+15+15=60ft.

Length of Line from Corner to Corner:

(15)(15)+(15)(15)=C^2

225+225=C^2

Answer:

The measure of angle JKM is 108°

Step-by-step explanation:

step 1

Find the value of x

we know that

The sum of the interior angles of a triangle must be equal to 180 degrees

so

∠M+∠L+∠MKL=180°

substitute the given values

4x+5x+6x=180°

15x=180°

x=12°

step 2

Find the measure of angle JKM

we know that

Angles MKL and JKM are supplementary angles

so

∠MKL+∠JKM=180°

6x+∠JKM=180°

substitute the value of x

6(12)+∠JKM=180°

∠JKM=180°-72°=108°

Answer:

108

Step-by-step explanation:

We know sum of all the 3 angles in a triangle is equal to 180. We can set up an equation for the triangle KML using the information given:

[tex]4x+5x+6x=180\\15x=180\\x=\frac{180}{15}=12[/tex]

So measure of Angle MKL is 6x, or 6(12) = 72

Now, we know Angle JKM + Angle MKL = 180 (straight line). Thus,

Angle JKM + 72 = 180

Angle JKM = 180 - 72 = 108

Answer:

Step-by-step explanation:

Using the addition identity for sine

sin(x + y) = sinxcosy - cosxsiny

Consider the left side

cos²(45 - A) - sin²(45 - A)

cos²(45 - A) = 1 - sin²(45 - A), thus

1 - sin²(45 - A) - sin²(45 - A)

= 1 - 2sin²(45 - A) ← expand sin(45 - A)

= 1 - 2(sin45cosA - cos45sinA)²

= 1 - 2([tex]\frac{\sqrt{2} }{2}[/tex]cosA - [tex]\frac{\sqrt{2} }{2}[/tex]sinA)²

= 1 - 2([tex]\frac{1}{2}[/tex]cos²A - sinAcosA + [tex]\frac{1}{2}[/tex]sin²A)

= 1 - cos²A + 2sinAcosA - sin²A

= sin²A + 2sinAcosA - sin²A

= 2sinAcosA

= sin2A = right side ⇒ verified

By Using the addition identity for sine; sin(x + y) = sinx cosy - cosx siny.

It is proved that cos²(45 - A) - sin²(45 - A)= Sin2A.

We can use the fact that:

[tex]\sin(\theta ^\circ) = \cos(90 - \theta^\circ)[/tex]

To convert the sine to cosine (but the angles won't stay the same unless it's 45 degrees).

Using the addition identity for sine

sin(x + y) = sinx cosy - cosx siny

Now,

cos²(45 - A) - sin²(45 - A)

cos²(45 - A) = 1 - sin²(45 - A),

1 - sin²(45 - A) - sin²(45 - A)

= 1 - 2sin²(45 - A)  

Expand sin(45 - A)

= 1 - 2(sin45cosA - cos45sinA)²

= 1 - 2(√2/2 cosA - √2/2 sinA)²

= 1 - 2(1/2 cos²A - sinAcosA + 1/2 sin²A)

= 1 - cos²A + 2sinAcosA - sin²A

= sin²A + 2sinAcosA - sin²A

= 2sinAcosA

cos²(45 - A) - sin²(45 - A) = sin2A = right side

Hence, it is verified.

Answer: [tex]b=1[/tex]

Step-by-step explanation:

Given the equation [tex]-3(-8b+7)=3(2b-1)[/tex] you need to solve for the variable "b".

You need to apply Distributive property on both sides of the equation:

[tex]-3(-8b+7)=3(2b-1)\\\\24b-21=6b-3[/tex]

Now you need to add 21 to both sides of the equation:

[tex]24b-21+21=6b-3+21\\\\24b=6b+18[/tex]

Subtract [tex]6b[/tex] from both sides:

[tex]24b-6b=6b+18-6b\\\\18b=18[/tex]

And finally, you can divide both sides of the equation by 18:

[tex]\frac{18b}{18}=\frac{18}{18}\\\\b=1[/tex]

Answer:

b=1

Step-by-step explanation:

You first need to multiply -3 and -8b. That will be 24b. Then you multiply -3 times 7. That will be -21. On the other side, you will multiply 3 times 2b which will equal 6b. Then you multiply 3 by -1. You will get -3. So at this point, the equation should look like this, 24b-21=6b-3. Then add 21 to both sides. You will have this equation, 24b=6b+18. Then subtract 6b from both sides, 18b=18. Finally, divide 18 from both sides to get your final answer of b=1.

They're not equivalent.

[tex]|x|[/tex] (vertical bars) represents the absolute value of x. How it works is that it turns negative numbers positive but leaves 0 and positive numbers alone (hence it gets a number's distance from 0 on the number line).

[tex][x][/tex] (square brackets) usually represents the floor function, which returns the largest integer that is less than or equal to x. (The floor of x can also be written as [tex]\lfloor x \rfloor[/tex] --- it depends on what your textbook/source says).

To solve [tex]|x| - 3 = 7[/tex], you first transform it into the equivalent equation [tex]|x| = 10[/tex]. Then by definition of absolute value, there are only two solutions for the first equation: x = 10 or x = -10.

[x] = 10 has infinitely many solutions. For example, the floor of 10 is 10, so [tex][10] = 10[/tex], thus a solution for the second equation is x = 10

The floor of 10.1 is 10, so [tex][10.1] = 10[/tex], thus another solution for the second equation is x = 10.1.

The two equations do not have the same solution set (as x = 10.1 does not solve |x| - 3 = 7 but solves [x] = 10), so they're not equivalent.

ANSWER

[tex] \log_{4}(3x + 4) = 2[/tex]

EXPLANATION

Consider the equation:

[tex] \log_{4}(3x + 4) = 2[/tex]

When we rewrite this logarithmic equation in the exponential form, we obtain:

[tex]3x + 4= {4}^{2} [/tex]

Note that to write a logarithmic equation in exponential form, the base of the logarithm is still the base in the exponential form.

We now simplify the RHS.

[tex]3x + 4 = 16[/tex]

Group like terms

[tex]3x = 16 - 4[/tex]

This implies that

[tex]3x = 12[/tex]

Divide both sides by 3

[tex] \frac{3x}{3} = \frac{12}{3} [/tex]

Simplify to get;

[tex]x = 4[/tex]

Hence the equation that has x=4 as a solution is

[tex] \log_{4}(3x + 4) = 2[/tex]

Another way to do this is to substitute x=4 into each equation. The equation that is satisfied is the correct choice.

The correct answer option is D. He multiplied the divisor by 100 and dividend by 10.

Step-by-step explanation:

We are given that Miguel completed the division where initially he had to divide 754 by 0.52.

To make it easier, he multiplied both the divisor and the dividend by the same number to get rid of the decimal in the divisor.

If he multiplied the divisor by 100, he should have multiplied the dividend by 100 too. But instead, he mistakenly multiplied the divisor by 100 and dividend by 10.

Answer:

So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number. Proof: "The product of two rational numbers is rational."

Sum of two rational numbers is always a rational number is always true .

A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. For example, −3/7 is a rational number, as is every integer

According to the question

The sum of two rational numbers :

Case 1: Consider rational numbers with different denominator : [tex]\frac{4}{5} , \frac{2}{3}[/tex]

Sum of both rational numbers

=  [tex]\frac{4}{5} + \frac{2}{3}[/tex]

= [tex]\frac{12 + 10 }{15}[/tex]

= [tex]\frac{22}{15}[/tex]

Case 2:Consider rational numbers with same denominator : [tex]\frac{4}{5} , \frac{1}{5}[/tex]

= [tex]\frac{4}{5} + \frac{1}{5}[/tex]

= [tex]\frac{5}{5}[/tex]

= [tex]\frac{1}{1}[/tex]

= 1

Sum in both cases are rational numbers

Hence, Sum of two rational numbers is always a rational number is always true .

Step-by-step explanation:

Let x represent number of stereos.

We have been given that a salesman sold each stereo for $1500. He earned a commission of 16.5% on each stereo sold.

The amount of commission earned on each stereo would be 16.5% of 1500.

[tex]1500\times \frac{16.5}{100}=15\times 16.5=247.5[/tex]

The amount of commission earned on x stereos would be [tex]247.5x[/tex].

We are told his base salary is $33,170, so total salary of salesman would be [tex]247.5x+33,170[/tex].

We are also given that last year he earned $37,625. We can represent this information in an equation as:

[tex]247.5x+33,170=37,625[/tex]

[tex]247.5x+33,170-33,170=37,625-33,170[/tex]

[tex]247.5x=4455[/tex]

[tex]\frac{247.5x}{247.5}=\frac{4455}{247.5}[/tex]

[tex]x=18[/tex]

Therefore, the salesman sold 18 stereos last year.

Step-by-step explanation:

We have been given that Yvette earns 12% commission on any sales over $10,000. Last year Yvette made $30,000 in sales.

The amount on which Yvette will get commission would be [tex]\$30,000-\$10,000=\$20,000[/tex].

Since Yvette gets 12% commission, so amount earned as commission would be 12% of $20,000.

[tex]\text{Commission}=\$20,000\times \frac{12}{100}[/tex]

[tex]\text{Commission}=\$20,000\times 0.12[/tex]

[tex]\text{Commission}=\$2,400[/tex]

Yvette also gets a salary of $45,000, so Yvette's total earnings would be $45,000 plus $2,400.

[tex]\text{Yvette's total earnings}=\$45,000+\$2,400[/tex]

[tex]\text{Yvette's total earnings}=\$47,400[/tex]

Therefore, Yvette's earned $47,400 in salary plus commission.

Answer:

1.5 hours is the correct answer !

Step-by-step explanation:

Speed is the rate of distance over time.

The equations are:

The given parameters are:

[tex]\mathbf{(t_1,d_1) = (1:30pm,35miles)}[/tex]

[tex]\mathbf{(t_2,d_2) = (4:30pm,230miles)}[/tex]

So, the time difference is:

[tex]\mathbf{t=4:30pm - 1:30pm}[/tex]

[tex]\mathbf{t=3\ hours}[/tex]

The distance traveled is:

[tex]\mathbf{d = 230miles - 35miles}[/tex]

[tex]\mathbf{d = 195miles}[/tex]

Speed is calculated as:

[tex]\mathbf{Speed = \frac{Distance}{Time}}[/tex]

So, we have:

[tex]\mathbf{Speed = \frac{195\ miles}{3\ hours}}[/tex]

Multiply both sides by 3 hours

[tex]\mathbf{3\ hours \times Speed = 195\ miles}[/tex]

Divide both sides by Speed

[tex]\mathbf{3\ hours = \frac{195\ miles}{Speed}}[/tex]

Hence, the equations are:

[tex]\mathbf{Speed = \frac{195\ miles}{3\ hours}}[/tex]

[tex]\mathbf{3\ hours \times Speed = 195\ miles}[/tex]

[tex]\mathbf{3\ hours = \frac{195\ miles}{Speed}}[/tex]
