Answer:

120.4ft

Step-by-step explanation:

Find the diagram in the attachment.

The triangle shown is a right angled triangle with the side DE as the hypotenuse, EF is adjacent side while DF is the opposite side.

To get DE, we will use the SOH CAH TOA trigonometry identity

Using CAH which is defined as:

Cos(theta) = Adjacent/Hypotenuse

Cos 79°= 23/Hypotenuse

Hypotenuse = 23/cos79°

Hypotenuse = 23/0.191

Hypotenuse = 120.4feet

DE = 120.4feet (to nearest tenth)

Answer:

Step-by-step explanation:

The triangle DEF is right angle triangle

The missing  F

F=90 E=79 = 11

E=79 EF= 23

Find the Length of DE to the nearest tenth of a foot

Answer:

HA < CH because MHA is a right triangle and CAH is an acute triangle which means that it is smaller

Step-by-step explanation:

Answer:

HM > CH

Step-by-step explanation:

In ∆ HAM,

m<HAM=90°

and, in ∆ CHK

m<HKC= 73°

angle HAM > angle HKC

Therefore, side opposite to angle HAM > side opposite to angle HKC

Given:

∠1 = 2x+6 ans ∠2= -x+24

To find the values of ∠1 and ∠2.

Formula:

The values of the vertical angles are always equal.

Here,

∠1 and ∠2 are vertical angles.

So, by this condition,

∠1=∠2

or,[tex]2x+6 = -x+24[/tex]

or, [tex]2x+x = 24-6[/tex] [ Taking all the variables in one side and all the constant in other side]

or, [tex]3x = 18\\[/tex]

or, [tex]x = \frac{18}{3}[/tex]

or, [tex]x = 6[/tex]

So,

∠1 = [tex]2(6)+6 = 18^\circ[/tex]

∠2 =[tex]-6+24 = 18^\circ[/tex]

Hence,

The values of ∠1 and ∠2 are 18°.

Answer: 165.6

Step-by-step explanation:

The formula for finding the interior angle of a polygon is

= (2n - 4) x right angle

= (2n - 4)90 ,or

(n - 2)180

Now since the sum total of the interior angle of the 25 sided regular polygon = 4140 using the formula above,

Therefore, the value of each of the interior angle will be

= 4140/25

= 165.6

Final answer:

Each interior angle of a regular 25-sided polygon, with sum of the interior angles at 4140 degrees, measures 165.6 degrees.

Explanation:

The sum of the measures of a regular 25-sided polygon is 4140 degrees. To find the measure of each interior angle of a regular polygon, we use the formula:

(n - 2) × 180° = Sum of interior angles,

where n is the number of sides in the polygon. Since we are given that the sum of the interior angles is 4140 degrees for a 25-sided polygon, we can plug in the values into our formula:

(25 - 2) × 180° = 4140 degrees,

which simplifies to:

23 × 180° = 4140 degrees.

This confirms the given sum of the interior angles. To find the measure of one interior angle, we divide the sum by the number of angles:

4140 degrees ÷ 25 = 165.6 degrees.

So the measure of each interior angle in a regular 25-sided polygon is 165.6 degrees.

Answer:

55, 125 and 125

Step-by-step explanation:

In this question, we are asked to find the other 3 angles in an intersection.

Please check attachment for what the diagram of the intersection might look like.

The intersection consists simply of 4 angles meeting at a point with the 2 angles on each side vertically opposite to the angles on the other side.

since one of the angles is 55, and we are having a straight line, the other angle would be 180-55 = 125.[ sum of angles on a straight line is 180]

These two angles are vertically opposite, this means that the other three angles are 55,125 and 125.

Answer:

The degree of freedom for the test is 27.

Step-by-step explanation:

The experiment performed by the researcher is to determine the number of time the rat touches the specific object compared to a different object.

The parameter under study is the mean number of times the rat touches the specific object.

The hypothesis for the test is defined as:

H₀: The mean number of times the rat touches the specific object is not more than that for a different object, i.e. μ ≤ μ₀.

Hₐ: The mean number of times the rat touches the specific object is more than that for a different object, i.e. μ > μ₀.

A t-test for single mean is performed.

The information provided is:

α = 0.05

t = 2.842

n = 28

The degrees of freedom for a single mean t-test is:

df = (n - 1)

   = 28 - 1

   = 27

Thus, the degree of freedom for the test is 27.

Answer:

The ratio is 3:1

Step-by-step explanation:

Let

x --->number of neck less sold via the shop website

y --->number of neck less sold in a high street shop

we know that

To find out the ratio of online sales to shop sales, simply divided the number of neck less sold via the shop website by the number of neck less sold in a high street shop

so

[tex]ratio=\frac{x}{y}[/tex]

we have

[tex]x+y=240[/tex] ----> equation A

[tex]x=180[/tex] ---> given value

substitute the value of x in the equation A

[tex]180+y=240[/tex]

solve for y

[tex]y=240-180=60[/tex]

Find the ratio

[tex]ratio=\frac{180}{60}[/tex]

[tex]ratio=\frac{3}{1}[/tex]

To multiply monomials, you multiply the coefficients and add the exponents of like variables. The product of -9n^3 and n^3 is -9n^6.

The question is about multiplying two monomials in mathematics. In this case, the two monomials are -9n^3 and n^3. To multiply monomials, you multiply the numerical coefficients and add the exponents of like variables. Here, the coefficient is -9 and the exponent 3 for the first monomial and 1 and 3 for the second monomial. When you multiply -9 by 1, you get -9. When you add the exponents 3 and 3, you get 6. So, the product of those two monomials in standard form is -9n^6.

The applicable rules of logarithms are ...

  log(ab) = log(a)+log(b)

  log(a^b) = b·log(a)

Final answer:

To expand the expression In 2a³/b⁴, you apply logarithm properties to obtain In 2 + 3 In a - 4 In b, which separates the factors into individual log terms.

Explanation:

The question asks us to expand the logarithmic expression In 2a³/b⁴ using logarithm properties. The correct expansion of this expression is given by the sum of the logarithms of the numerator's factors minus the sum of the logarithms of the denominator's factors. Applying the properties of logarithms (product to sum and quotient to difference), we obtain the expansion as follows:

In 2a³/b⁴ = In 2 + In a³ - In b⁴

The logarithm of a power (such as In a³ and In b⁴) can be brought down as a coefficient:

In 2 + 3 In a - 4 In b

Thus, the correct expansion is In 2 + 3 In a - 4 In b.

Answer: $9

Step-by-step explanation: If Wendy wants to own a total of 12 necklaces, that means Wendy wants to buy 9 more necklaces, since she already owns 3. We know that each necklace is a dollar.

So if Wendy buys 9 necklaces for a dollar each, then the total price will be $9 for Wendy to own a total of 12 necklaces.

( 9 x 1 = 9)

Wendy has 3 necklaces, and she needs a total of 12. So 12 - 3 is 9. She'll need to buy 9 more necklaces.

If each necklace cost $1, that means for 9 necklaces she will spend $9.

1 × 9 = 9

That means $9 has to be spent, in order to own 12 necklaces.

Final answer:

To find out how many pizzas Charlie can make in one hour, divide the total number of pizzas he can make by the total number of hours he spends making them. Charlie can make 25 pizzas in one hour.

Explanation:

To find out how many pizzas Charlie can make in one hour, we need to divide the total number of pizzas he can make (125) by the total number of hours he spends making them (5).
