NEED ASAP!!Find The Surface Area Of The Pyramid.

Answers

Answer 1

A ≈ 473.63

Step-by-step explanation: To find the surface area for a pyramid, we can use this formula: [tex]A=lw+l\sqrt{(\frac{w}{2})^2 } +h^2+w\sqrt{(\frac{l}{y} } )^2+h^2[/tex]

Solution: [tex]10\times10+10\times\sqrt{(\frac{10}{2} } )^2+18^2+10\times\sqrt{(\frac{10}{2} } )^2+18^2=423.63[/tex]

On a coordinate plane, the orange K is shifted to form the purple K, reflected across the x-axis to form the green k, and rotated to form the black k. Which image is a reflection of the orange letter K in Quadrant I?

Answers

Answer:

the green kin quadrant IV

Step-by-step explanation:

i took the quiz and got it right

Point k is reflected across the y-axis to create point k'.

What is reflection?

A reflection in mathematics is a mapping from a Euclidean space to itself that is an isometry with a set of fixed points known as the hyperplane, also known as the axis or plane of reflection.

The mirror image of a figure in the axis or plane of reflection is the image produced by a reflection.

From the graph, we can see that point k has a negative x-coordinate, so option A is wrong. Also, point K is located in quadrant II, not in quadrant IV

Point K is not reflected across the x-axis to create K'. For reflection across the x-axis to occur, the point (x,y) across the x-axis will change to (x, -y).

Point K is reflected across the y-axis to create point K'. We can see from the graph that the reflection of the point (x,y) across the y-axis is the point (-x, y)

Staples sells boxes of pens for ($10) and rubber bands for ($24). Leona ordered a total of 24 cartons for $210. How many boxes of each did Leona order? Hint: Let P = Pens.

Answers

Answer:

Leona ordered 19 boxes of pens and 5 rubber bands

Step-by-step explanation:

Let there are p pen and b rubber bands.

ATQ,

p+b = 24 ...(1)

and

10p+4b = 210 ...(2)

Multiply equation (1) by 10.

10p+10b = 240 ...(3)

Subtract equation (2) from (3).

10p+10b-(10p+4b ) = 240-210

6b = 30

b = 5

Put the value of b in equation (1).

p+5 = 24

p = 19

Hence, Leona ordered 19 boxes of pens and 5 rubber bands.

Yasmin arived home from play practice began 20 minutes after the final bell and lasted for a half hour. When did school end.

Answers

Answer:

the school ended at 3:20pm

Step-by-step explanation:

Since Yasmin arrived home from play practice at 4:25 p.m.

The walk home took 15 minutes.

And, The practice starts 20 minutes after the final bell and lasted for a half hour.

Now Total time taken in all activities would be

= 15 + 20 + 30

= 65 minutes

Now deduct 1 hour and 5 minutes from 4:25 pm

i.e.

1 hour prior to 4:25 pm i.e. 3:25 pm

And, 5 minutes prior 3:25 pm i.e. 3:20 pm

So, the school ended at 3:20pm

Part C: How many more dollars does Collins earn doing yard work for 5 hours than working as a dog walker for 5 hours? Show your work. (3 points)

Answers

Answer:

See below.

Step-by-step explanation:

Part A:

For Dog walking, he earns $30 for 5 hours of work.

He earns $36 for 6 hours of work.

$30/5 hours = $6/hour

$36/6 hours = $6/hour

He earns $6/hour dog walking.

For 8 hours, he earns 8 hours * $6/hour = $48

To earn $66, he works 66/6 = 11 hours.

5 30

6 36

8 48

11 66

Part B:

He earns $7/hour for yard work, so multiply the number of hours by 7 to find the money he earns.

Table for yard work

Hours     Money

5             $35

6             $42

8             $56

Part C:

For 5 hours, he earns $35 for yard work and $30 as a dog walker.

$35 - $30 = $5

Step-by-step explanation:

The slope is the rise over the run. 2 simple coordinates I can see is (6,2) and (7,4). I usually like to visualize it instead of actually solving it mathematically. So, we can start at (6,2). The point (6,2) goes up 2 and 1 to the right in order to get (7,4.) So since the slope is rise over run ( y/x) it would be 2/1 because we went 2 up the y axis and 1 to the right of the x axis. So 2/1 is 2. Therefore, 2 is the answer.  I'm sorry if my explaining isn't the best... I hope this helps though!!

To prepare for a party, Jada poured 0.45 liter of juice into each of several cups. Altogether she poured 9 liters of juice into the cups.

Answers

Answer: 20 cups

Step-by-step explanation:

Question would like to know the number of cups that Jada poured juice into.

If each cup got 0.45 litres, the number of cups that Jada poured drinks into would be the total amount of juice poured divided by the quantity per cup:

= Total juice poured / Quantity per cup

= 9 litres/ 0.45 litres per cup

= 20 cups

Step-by-step explanation:

i just did this one lol

The system of equations that describes the problem situation is y=250+0.12x and y=475+0.08x. The correct option is D.

What are Percentages?

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given that The first store will pay her a weekly salary of $250 plus a commission of 12% of her sales. Therefore, the equation can be written as,

Total earning = Weekly salary + 12% of weekly sales

y = 250 + 0.12x

Also, The second store will pay her a weekly salary of $475 plus an 8% commission. Therefore, the equation can be written as,

Total earning = Weekly salary + 8% of weekly sales

y = 475 + 0.08x

Hence, the system of equations that describes the problem situation is y=250+0.12x and y=475+0.08x.
