help please i’m not sure what 17, 18, 19, and 20 are

Answers

Answer:

17. 25 [tex]in^2[/tex]

18. 53 [tex]m^2[/tex]

19. 21.6 [tex]cm^2[/tex]

20. 20.8 [tex]km^2[/tex]

Step-by-step explanation:

The area of a parallelogram is simply the base multiplied by the height.

17.

Base = 5 in

Height = 5 in

Area = Base * Height

Area = 5 * 5

Area = 25 [tex]in^2[/tex]

18.

Base = 10 m

Height = 5.3 m

Area = Base * Height

Area = 10 * 5.3

Area = 53 [tex]m^2[/tex]

19.

Base = 5.4 cm

Height = 4 cm

Area = Base * Height

Area = 5.4 * 4

Area = 21.6 [tex]cm^2[/tex]

20.

Base = 5.2 km

Height = 4 km

Area = Base * Height

Area = 5.2 * 4

Area = 20.8 [tex]km^2[/tex]

A student bought a calculator and a textbook for a course in algebra. He told his friend that the total cost was $115 (without tax) and that the calculator cost $20 more than four times the cost of the textbook. What was the cost of each item? Let x= the cost of a calculator and y= the cost of the textbook. The corresponding modeling system is {x+y=115x=4y+20. Solve the system by using the method of substitution.

Answers

Answer:

X=$96

Y=$19

Step-by-step explanation:

x=4y+20

X+Y=$115

4Y+20+Y=$115

5Y+20=$115

-20 -20

5Y=$95

/5 /5

Y=$19

X=4 x $19 + $20

X=$76+$20

X=$96

In linear equation, cost of calculator = $96 , cost of textbook = $19 is the cost of each item .

What are instances of linear equations?

Ax+By=C represents a two-variable linear equation in its standard form. A standard form linear equation is, for instance, 2x+3y=5.Finding both intercepts of an equation in this form is rather simple (x and y).When resolving systems of two linear equations, this form is also incredibly helpful.

let cost of calculator = x

cost of textbook = y

x=4y+20 .................(1)

X+Y= 115 .................(2)

put value of equation 1 in 2

4Y+20+Y= 115

5Y+20= 115

5Y = 115 - 20

5Y = 95

Y = 95/5

Y = 19

Put value of y in equation 1

X=4 x 19 + 20

X= 76+ 20

X= 96

cost of calculator = 96

cost of textbook = 19

Write the equation of the circle with the given information.
Center: (5, -13)
Radius: 11

Answers

Answer:

(x - 5)² + (y + 13)² = 121

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (5, - 13 ) and r = 11 , then

(x - 5)² + (y - (- 13))² = 11² , that is

(x - 5)² + (y + 13)² = 121

Students applying to law school must take the LSAT exam. Since competition for acceptance is stiff, many students take a course that is advertised to boost scores on the LSAT. The agency that teaches the course claims the course is an effective way to raise scores on the LSAT. To test this claim, a group of students are given the LSAT and their scores are recorded. They then attend the course for 5 wecks and retake the exam. Their scores are recorded again. The pre and post test scores are saved here (for Minitab 19) or here (for Minitab 18).
a. Are the samples independent or dependent? Explain.
b. What are the appropriate null and alternative hypotheses for testing the claim that the course is an effective way to raise scores on the LSAT?

Kaila wants to borrow $175,000 for her mortgage.Timberwolf Bank offers a 15-year mortgage at an APR of 4.5%.

Answers

Answer:

At the end of the mortgage, $ 293,125 will have been paid.

Step-by-step explanation:

Given that Kaila wants to borrow $ 175,000 for her mortgage, and Timberwolf Bank offers a 15-year mortgage at an APR of 4.5%, to determine the amount to be repaid after the end of the mortgage, the following calculation must be performed:

175,000 x (1 + 15 x 4.5 / 100) = X

175,000 x (1 + 67.5 / 100) = X

175,000 x (1 + 0.675) = X

175,000 x 1,675 = X

293.125 = X

Therefore, at the end of the mortgage, $ 293,125 will have been paid.

Answer:

A. 1 hour and 16 minutes

Step-by-step explanation:

There are 250 mL of D5W infusing at 33 gtt/min on IV tubing calibrated at 10 gtt/mL. Calculate the infusion time.

select "No IV pump"

volume = 250 mL

rate = 33 gtt/min

calibration = 10 gtt/mL

Actual formula:

250 /( 33 gtt/min

10x 60)= 1.26 Hours

0.26 x 60 = 16 minutes

So 1.26 Hours = 1 Hour & 16 minutes

find the value of x.

Answers

Answer:

x = 14.5

Step-by-step explanation:

This is a supplementary angle, meaning the sum of the angles is 180°.

We can find the value of x by combining like terms.

5x - 6 + 7x + 12 = 180.

5x and 7x are alike.

5x + 7x = 12x.

-6 + 12 = 6.

The final equation is 12x + 6 = 180.

We can solve this by subtracting 6 from 180.

180 - 6 = 174.

12x = 174

Lastly, we divide 174 by 12.

174 / 12 = 14.5

Therefore, x is equal to 14.5

Were the lessons for poetry in-depth? Did they make you think? Or were they just simple things like reading and writing a few poems and answering some questions on famous poems. Lessons about poetry always seem so short and brief. It never feels like kids are being taught in-depth poetry. Its always just the basics like some of the types of poetry written or why poetry is important. Teachers dont usually teach the emotional connection poetry has so when kids get up into high school English, they struggle when learning poetry. Some English teachers in high school expect emotional connections to the poems or in-depth poems but since kids aren't taught how to do that throughout Elementary and Middle school, they struggle and cant do it. Poetry should be taught more in school because there are so many things that poetry does for us, such as helping express emotions and feelings, strengthens overall mental health, and its even therapeutic for the writer and reader.
