A) 38°
B) 60°

D) 71°

Answers

Answer:

A: 38º

Step-by-step explanation:

Triangle JKL is an isosceles triangle as JK=KL:

That means ∠J=∠L=71ºThe sum of a triangle's interior angles is 180º, so ∠K=180º-∠J-∠L. We know ∠J=∠L=71º, so ∠K=180º-71º-71º=38

In training for a swim meet, Logan swam 750 meters in \large \frac {1}{3} 3 1 ​ of an hour. His swimming partner, Mila, swam \frac {2}{3} 3 2 ​ of Logan's distance in \frac {1}{4} 4 1 ​ of an hour. what is milas average speed

Answers

Answer:

2 km/hr

Step-by-step explanation:

Distance traveled by Logan = 750 m = 0.75 km = [tex]\frac{3}{4}\ km[/tex]

Time taken by Logan = [tex]\frac{1}{3}\ hours[/tex]

To calculate the speed using time and distance, following formula is used:

[tex]\text{Average Speed =} \dfrac{\text{Total Distance}}{\text{Total Time}}[/tex]

Speed of Logan :

[tex]\dfrac{\frac{3}{4}}{\frac{1}{3}}\\\Rightarrow \dfrac{9}4\ km/hr[/tex]

Distance traveled by Mila = [tex]\frac{2}{3}[/tex] of Logan's distance:

[tex]\frac{2}{3}\times \frac{3}{4} = \frac{1}{2}\ km[/tex]

Time taken by Mila = [tex]\frac{1}{4}\ hr[/tex]

As per formula above:

Average Speed of Mila is given as:

[tex]\dfrac{\frac{1}{2}}{\frac{1}{4}}\\\Rightarrow \dfrac{4}{2}\\\Rightarrow \bold{2 km/hr}[/tex]

Ellen wants to purchase a book that is regularly priced at $18. The book is discounted 15%. She also needs to pay a 6% sales tax on the discounted price.

What is the total amount Ellen will pay for the book?

Answers

Answer:

$16.22

Step-by-step explanation:

When 18 dollars is discounted by 15%, we first need to find what 15% of 18 is. 18 times .15 is 2.7, and 18-2.7 is 15.3.

Then, we need to find the sales tax, which applies to the discounted price. 15.3 times 0.06 is 0.918. Add that to 15.3 and you get 16.218, or about $16.22. Hope this helped! :D

Consider the polynomial function h(x) = -7x6 + 3x4 – 5x2.
What is the end behavior of the graph of h ?

Answers

Answer: As x -> ♾, h(x) -> -♾, and as x -> -♾,h(x) -> -♾

Step-by-step explanation:

The end behavior is x ----> ∞ then h(x) ----> -∞, and when x ----> -∞ then h(x) -----> -∞.

What is Function?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

h(x) = -7[tex]x^6[/tex] + 3 [tex]x^4[/tex]– 5x².

If we plot the Equation on the Graph we can see a parabolic Curve.

This Curve tells as x tends to ∞ the value of h(x) tends to -∞.

and, when x tends to -∞ the value of h(x) tends to -∞.

Hence, the end behavior is x ----> ∞ then h(x) ----> -∞.

and, when x ----> -∞ then h(x) -----> -∞.

You are going to make three shelves for your father and have one piece of lumber 20 feet long. Your plan is to make the top shelf half a foot shorter than the middle shelf and to have the bottom shelf half a foot shorter than twice the length of the top shelf. How long is each shelf? t= length of the top shelf t=m-1/2 m = length of middle shelf b = length of bottom shelf. B=2t-1/2 t+m+b=20

Answers

Answer:

The top shelf is 5 feet, the middle shelf is 5.5 feet and the bottom shelf is 9.5 feet

Step-by-step explanation:

Let t= length of the top shelf, m = length of middle shelf and b = length of bottom shelf.

Therefore:

t = m - 1/2; m = t  + 1/2

Also, b = 2t - 1/2

The total of the three shelves is 20 feet, therefore:

t + m + b = 20

Substituting:

t + t + 1/2 + 2t - 1/2 = 20

4t = 20

t = 20/4

t = 5 feet

m = t + 1/2 = 5 + 1/2 = 5.5 feet

b = 2t - 1/2 = 2(5) - 1/2 = 9.5 feet

The top shelf is 5 feet, the middle shelf is 5.5 feet and the bottom shelf is 9.5 feet

Answers

Answer:

Mr. Patio paid $312.00 for the three watches

Step-by-step explanation:

The price of one of the Casio G-Shock watches that  Mr. Patel bought his 3 friends for Christmas is $39.91.

For Mr. Patio to have bought this watch for each of his 3 friends, we have that the cost will be multiplied by three. He is spending three times the amount he would have spent if he is buying for only a single person.

Cost = 39.91 X 3 =$312.00

Mr. Patio paid $312.00 for the three watches

Given the system of equations presented here:

4x + y = 4
2x + 6y = 24

Which action creates an equivalent system that will eliminate one variable when they are combined?

Multiply the first equation by −4 to get −16x − 4y = −16.
Multiply the second equation by −4 to get −8x − 24y = −96.
Multiply the first equation by −2 to get −8x − 2y = −8.
Multiply the second equation by −2 to get −4x − 12y = −48.

Answers

Answer:

Multiply the second equation by −2 to get −4x − 12y = −48.

Step-by-step explanation:

Given:

4x + y = 4 (1)

2x + 6y = 24 (2)

Multiply the second equation by −2 to get −4x − 12y = −48.

4x + y = 4 (1)

−4x − 12y = −48 (3)

Variable x can be eliminated by adding the equations

4x + (-4x) + y + (-12y) = 4 + (-48)

4x - 4x + y - 12y = 4 - 48

0 - 11y = -44

-11y = -44

Divide both sides by -11

y = -44/-11

= 4

y = 4

Answer: Multiply the second equation by −2 to get −4x − 12y = −48.

The mean weight of the domesticated house cat is 9.2 pounds with a standard deviation of 3.4 pounds. If a cat has a z-score of -1.3 for its weight, how much does it weigh? Write your answer as a complete sentence.

Answers

Answer:

4.78 pounds

Step-by-step explanation:

We solve the above question using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean = 9.2 pound

σ is the population standard deviation = 3.4 pounds

z = 1.3

We are to find x

Hence,

-1.3 = x - 9.2/3.4

Cross Multiply

-1.3 × 3.4 = x - 9.2

-4.42 = x - 9.2

x = -4.42 + 9.2

x = 4.78 pounds.

Therefore the weight of the cat is 4.78 pounds
