In △CDE , CD=10 , DE=7 , and m∠E=62∘ . What is m∠D to the nearest tenth of a degree?

Answer:

The answer is 5.

Step-by-step explanation:

Multiplicative rate of change can be described as the rate change based on a original amount or point.

If we look at the given points for the function f(x) = 2.5x, we can see that the x coordinates increase by one while the y coordinate is increasing by 5 times it's value for the previous point.

So we can say that the multiplicative rate of change is 5 for the function f(x) = 2.5x.

I hope this answer helps.

Answer:

25

Step-by-step explanation:

from the information given, we know that rps + qpr = qps.

so, (8x+7)+(9x+16) = 40.

simplify to get 17x + 23 = 40.

17x = 17.

x = 1.

plug in: 9+16 = 25.

Answer:

4 meters. 

Step-by-step explanation:

Benjamin has walked two legs of a right triangle, so you can connect her two movements with a line if you were sketching the situation.. The displacement is the objects overall change in position in relation to its origin, so in your case, Benjamin's apartment. While the total distance adds up regardless of her position. 

So, the total distance Benjamin walked is 10m + 6m = 16m 

Her displacement can be found by your best friends, the Pythagorean Theorem: 10m ^2 + 6m ^2 = delta x^2 (or displacement squared).. giving you a displacement of 11.66, or 12 m.

The difference between the distance she walked and her displacement is 4 meters.

Step-by-step explanation:

Test to determine if a function y=f(x) is even, odd or neither: Replace x with -x and compare the result to f(x). If f(-x) = f(x), the function is even. If f(-x) = - f(x), the function is odd.

Answer:

-pi

Step-by-step explanation:

as x equals zero, g(x) = -3.14 = -pi

Your answer would be the second option, -π.

This is because as x approaches 0, cos(x + π) approaches cos(π) = -1. On top, x + π as x approaches 0 will tend to π, so you end up with π/-1. This simplifies to -π.

I hope this helps! Let me know if you have any questions :)

Final answer:

The best estimate for the frog population, calculated using the mark-recapture method where 30 frogs were initially tagged and later 12 tagged frogs were found in a sample of 520, is approximately 208 frogs.

Explanation:

The question involves estimating the total population of frogs in a wetland area based on a mark-recapture study. The calculation is based on a proportion set up by the initial number of tagged frogs to the total initial tagging, compared with the number of tagged frogs found in a later sample to the size of that sample. This is a classic example of a capture-recapture method used in ecology for estimating population sizes.

The initial number of tagged frogs is 30, and later, from a sample of 520 frogs, 12 are found to be tagged. To estimate the total population (N), we set up the proportion as follows:

30 tagged frogs / N total population = 12 tagged frogs / 520 sample size

Now we cross-multiply and solve for N:

30N = 12 × 520

N = (12 × 520) / 30

N = 6240 / 30

N = 208

Therefore, the best estimate for the total frog population is approximately 208 frogs, rounded to the nearest whole number.

Answer:

(n -7)(4n + 8) = 0

Step-by-step explanation:

(a -b)² = a² - 2ab + b²

(2n - 5)² = 81

(2n)² - 2*2n*5 + 5² = 81

4n² - 20n + 25 = 81

4n² - 20n + 25 - 81 = 0

4n² - 20n - 56 = 0

4n² - 28n + 8n - 8*7 = 0

4n*(n -7) + 8*(n - 7) = 0

(n -7)(4n + 8) = 0

Using synthetic division suffices to answer your question:

Step-by-step explanation:

Synthetic division is the process by one reduces a large polynomial in your case [tex]x^3-7x-6[/tex] by a binomial in your case [tex](x+1)[/tex].

To do so one does the following:

[tex]\begin{array}{cccccc}-1|& 1&0&-7&-6\\ & &-1&1&6 \\& 1&-1&-6&0 \end{array}[/tex]

Since we divided by a linear binomial it reduces the power by one which produces the following quadratic:

[tex](x^2-x-6)[/tex]

Which can be factored in the following, and I will provide the complete factorization as well:

[tex]p(x)=(x+1)(x-3)(x+2)[/tex]

Answer:

38.5

Step-by-step explanation:

The perimeter is found by

P = 2( l+w)

We know the width is 23, we are looking for the length

P = 2 (23+l)

The perimeter is 123

123= 2 (23+l)

Divide each side by 2

123/2 = 23+l

61.5 = 23+l

Subtract 23 from each side

61.5 -23 = l

38.5 = l

The length of AB = 38.5

Rylee's total spending was $39.42 for clothing (including tax), $25 for gas, and $18.80 for groceries (after applying a 20% discount). Summing these up, her total expenditure for all purchases was $83.22.

This is a question involving basic arithmetic and percentage operations. In total, Rylee made three different purchases. She shopped for clothing costing $36.50 and paid 8% tax on it, which amounts to $36.50 * 0.08 = $2.92. Therefore, her total expenditure at the clothing store was $36.50 + $2.92 = $39.42. She then spent $25 to refuel her car.

Lastly, she bought groceries worth $23.50, but had a 20% discount coupon so she only paid 80% of the price, which is $23.50 * 0.80 = $18.80. If we add these expenditures together, we can find that Rylee's total spending was $39.42 (clothing) + $25 (gas) + $18.80 (groceries) = $83.22.

3. As the line nears closer to y = 0, Mrs. Washington is getting closer to her house. As such, the line represents miles driven per minute, representing speed. As the slope of the line becomes steeper, as it does during section B of the commute, Mrs. Washington is driving one mile per minute, or 60 miles per hour. As she drives through section C, she only drove 1 mile after 4 minutes, or 15 miles per hour.

4. She lives 20 miles from her office.

Step-by-step explanation:

1. You can find the slope for section B of the commute by taking two points in section B and using them to find the slope.

I will take (10, 13) and (14, 9) as my points.

You can use [tex]\frac{y2-y1}{x2-x1}[/tex] to find the slope:

[tex]\frac{13-9}{10-14} \\\\\frac{4}{-4}[/tex]

The slope for section b is -1.

2. You can find the slope for section C using the same method.

I will use the points (16, 7) and (20, 6):

[tex]\frac{7-6}{16-20} \\\\\frac{1}{-4}[/tex]

The slope for section c is -1/4.

3. As the line nears closer to y = 0, Mrs. Washington is getting closer to her house. As such, the line represents miles driven per minute, representing speed. As the slope of the line becomes steeper, as it does during section B of the commute, Mrs. Washington is driving one mile per minute, or 60 miles per hour. As she drives through section C, she only drove 1 mile after 4 minutes, or 15 miles per hour.

Answer:

So starting with what we already know, £100 was paid in all, all 100 seats were taken. Adults pay £3.50, Children pay $0.85 and the Pensioners pay $1.00. I basicaly started off by trying it so all adults, children and pensioners are the exact same number. 33 adult tickets would cost them £115.50. Crossing that suggestion out; I tried again, but this time, with 3 adults, 50 children and the 47 that were left, i put as pensioners. So, now there is 100 people and this is kind of working out:

3 adults= £10.50, 50 children= £42.50, 47 pensioners= £47.00 Total £100

Step-by-step explanation:

As per the given data number of adults [tex]=3[/tex] , number of children [tex]= 50[/tex] and number of pensioner [tex]= 47[/tex].

" Number is defined as the count of the given quantity."

According to the question,

Total number of seats [tex]=100[/tex]

Total amount of full seats [tex]= \£100[/tex]

Price of adult ticket [tex]= \£ 3.50[/tex]

Price of children ticket [tex]= \£ .85[/tex]

Price of adult ticket [tex]= \£ 1[/tex]

[tex]'x'[/tex]represents the number of adults

[tex]'y'[/tex] reprsents the number of children

[tex]'z'[/tex] represents the number of pensioner

As per given condition we have,

[tex]x + y + z = 100\\\\\£3.50x + \£0.85y + \£1z = \£ 100[/tex]

Using trial and error method we get,

[tex]x = 3 ,\\\\y= 50\\\\z= 47[/tex]

For total number of  tickets

[tex]3 + 50 + 47 = 100[/tex]

Left hand side = Right hand side

Substitute in left hand side of total cost we get,

[tex]\£3.50(3) + \£0.85(50) + \£1(47) \\\\= \£10.50 + \£42.50 + \£47[/tex]

[tex]= \£ 100[/tex]

= Right hand side

Hence, as per the given data number of adults [tex]=3[/tex] , number of children [tex]= 50[/tex] and number of pensioner [tex]= 47[/tex].

Answer: 119

Step-by-step explanation: got it right

In the given figure, measure of angle A is 61°, measure of angle B is 119° and measure of angle C is 62°.

From the given triangle triangle, exterior angle to the angle C is 118°.

We know that, sum of two adjacent angles is 180°.

Here, ∠C+118°=180°

∠C=180°-118°

∠C=62°

By using exterior angle theorem of triangle, we get

∠A+57°=118°

∠A=118°-57°

∠A=61°

So, ∠A+∠B=180° (Adjacent angles)

61°+∠B=180°

∠B=180°-61°

∠B=119°

Therefore, in the given figure, measure of angle A is 61°, measure of angle B is 119° and measure of angle C is 62°.
