Answer:

[tex]82,8m^2 = S.A[/tex]

Step-by-step explanation:

Area of a Rectangle: [tex]hb\:or\:wb = A[/tex]

Area of a Triangle: [tex]\frac{1}{2}hb; \frac{1}{2}bh, or\: \frac{hb}{2} = A[/tex]

Need to know

- Two small triangles

- Two big triangles

12m² = Rectangle

26,4m² EACH = Big Triangles

9m² EACH = Small Triangles

[tex]2[9] + 2[26,4] + 12 = 18 + 52,8 + 12 = 82,8[/tex]

So, the surface area of the rectangular pyramid is 82,8m².

* The answer is not 85,31 because this rectangular pyramid has two slant heights. If we ONLY had 9 as ONE SLANT HEIGHT, then the answer would have been 85,31, otherwise it is incorrect.

Answers

Answer:

PR = 20

Step-by-step explanation:

The perimeter is the sum of the 3 sides, thus

4z + z + 3 + 3z + 2 = 45 ← simplify left side

8z + 5 = 45 ( subtract 5 from both sides )

8z = 40 ( divide both sides by 8 )

z = 5

PR = 4z = 4 × 5 = 20

Answer:

40

Step-by-step explanation:

Using the triangle perimeter formula [P=2(l) + 2(w) / 2]:

45 = 2 (z + 3) + 2 (3z + 2) / 2

45 = 2z + 6 + 6z + 4 / 2

45 = 8z + 10 / 2

45 = 4z + 5

40 = 4z

z = 10

Answers

Answer:

$9.75 per hour

Step-by-step explanation:

243.75/25= 9.75

Hope this helps you out!

Answer:

Jeff is paid $9.75 for one hour of work.

Step-by-step explanation:

Jeff made last week = $243.75

He worked 25 hours for a week.

We have to calculate his pay per hour, so we divide his total pay by the time he worked.

total pay ÷ time he worked ( in hours)

pay per hour = 243.75 ÷ 25 = $9.75/hour

Jeff is paid $9.75 for one hour of work.

Marco took out an unsubsidized student loan for $20,000 which he will start paying in four years after he graduates if the interest rate is 4.2% what is the amount he will or once he graduates

Answers

Answer:

I'm going to assume that this is compound interest, as simple interest in this case would not make sense.

Let A be the final amount ( in this case, after 4 years). A = 20,000(1+0.042/12)^12*4. In this formula, I am assuming that the interest compounds 12 times a year, or every month. I am also assuming that he pays it off once he hits the 4-year mark.

If the assumptions are correct, he would be paying $23651.79 at the 4-year mark.

Step-by-step explanation:

Final answer:

Marco will owe approximately $23,521.93 on his unsubsidized student loan after graduation, calculated using the future value formula for a loan with compounded interest.

Explanation:

To calculate the amount Marco will owe after he graduates, we need to apply the formula for the future value of a loan when interest is compounded annually and no payments are made until after a certain period. Since Marco's unsubsidized student loan does not require payments while he is in school, the interest will be capitalized and added to the principal amount of the loan.

The formula for future value FV of a present value PV after n periods at an interest rate r is:

FV = PV * (1 + r)ⁿ

Where:

PV is the initial loan amount ($20,000)

r is the annual interest rate (4.2% or 0.042 as a decimal)

n is the number of periods (years in this case) before he starts repaying the loan (4 years)

Using the formula, we get:

FV = $20,000 * (1 + 0.042)⁴

FV = $20,000 * (1.042)⁴

F = $20,000 * 1.1760965435

FV = $23,521.93

Thus, Marco will owe approximately $23,521.93 once he graduates, before he starts making any payments on the loan.

Angle A is 5x-15. Angle B is 2x+21. Solve for x then find the measure for Angle B

Answers

To find the measure of Angle B, solve the equation 5x - 15 = 2x + 21, which gives x = 12. Then, substitute x back into the expression for Angle B to get 2(12) + 21 = 45°. Thus, Angle B measures 45°.

Solve for x and find the measure of Angle B

To solve for x and find the measure of Angle B, follow these steps:

Set the expressions for Angle A and Angle B equal to each other:
(5x - 15) = (2x + 21)Simplify the equation:
5x - 15 = 2x + 21Subtract 2x from both sides:
5x - 2x - 15 = 21Simplify further:
3x - 15 = 21Add 15 to both sides:
3x = 36Divide by 3:
x = 12

Now, substitute x back into the expression for Angle B:

Angle B = 2x + 21
= 2(12) + 21
= 24 + 21
= 45°

Therefore, the measure of Angle B is 45°.

For the 50 students in an art contest there will be 1 prize for 1st place, 1 prize for 2nd place, and 3 prizes for a honorable mention. What is the probability of winning a prize?

Answers

Final answer:

The problem involves calculating the probability of winning a prize in an art contest. The total prizes are 5 and the total students are 50. Therefore, the probability of winning a prize is 5/50 = 10%

Explanation:

The problem you're asking about is a classic question in the field of probability. In this case, we have 50 students entering an art contest. There are 1+1+3=5 prizes to be won. Therefore, the total number of ways of winning a prize is 5.

The total number of outcomes (which in this case is the total number of students) is 50. Thus, the probability of a student winning a prize can be calculated as the ratio of the number of ways of winning to the total number of outcomes. This gives us:

P(Winning a prize) = Number of ways of winning / Total number of outcomes = 5 / 50 = 0.1 or 10%.

So, each student has a 10% chance of winning a prize in the contest.

Find the value of x for which line a is parallel to line b

Answers

Answer:

20

Step-by-step explanation:

The question tells us that line a is parallel to line b (even if they don't seem to be in the image).

∠8 = ∠4 and ∠5 = ∠1 since line t crosses the parallel lines.

We are given ∠4 = 3x and ∠5 = 6x.

Since we know ∠8 = ∠4 , we can then say

∠8 = 3x and ∠5 = 6x

Since ∠8 and ∠5 are complementary and combined they form a flat angle of 180 degrees, we can say:

3x + 6x = 180

9x = 180

x = 20

Editor needs six cookies and 2 brownies for every 4 plates he makes for a bake sale cookies and brownies into the box to show how many editor needs for ten plates

Answers

Answer: 15 cookies and 5 brownies will be required.

Step-by-step explanation:

Given in the question is Eder needs 6 cookies and 2 brownies for 4 plates.

We have to calculate the cookies and brownies required for 10 plates.

Let's first calculate the cookies by unitary method.

⇒ 4 plates required cookies = 6 cookies

⇒  1 plate will require cookies = 6/4

⇒ 10 plates will require cookies = 6×10/4 = 15

Similarly we will calculate the brownies.

⇒ 4 plates required number of brownies = 2

⇒1 plate will require = 2/4 brownies

⇒10 plates will require = 2×10/4 = 5 brownies

⇒Therefore 15 cookies and 5 brownies will be required for 10 plates.

* Hopefully this helps:)

~ 234483279c20~

Final answer:

For 4 plates, an editor needs 1.5 cookies and 0.5 brownies. Thus, for ten plates, they will require 15 cookies and 5 brownies.

Explanation:

Let's start by determining the amount of cookies and brownies the editor needs for 4 plates. As per the given information, the editor needs 6 cookies and 2 brownies for every 4 plates. Therefore, for each plate, the editor will need to have 1.5 cookies (6/4 = 1.5) and 0.5 brownies (2/4 = 0.5).

Now, let's compute how much this would translate to if we have ten plates. Using the ratio we determined earlier, for ten plates the editor would need:

15 Cookies (1.5 cookies per plate * 10 plates)5 Brownies (0.5 brownies per plate * 10 plates)

This is the simplest way to figure out how many cookies and brownies are needed for a given number of plates, provided you know how much is needed per plate.

Ashley runs a hardware store. She has decided to apply a markdown of 15% to one item in order to draw customers into the store, and she will apply a markup of 10% to three different items, which she hopes the customers will purchase after purchasing the marked-down item. She has chosen four candidates for this process: a power drill with an initial price of $51.49, a ceiling fan with an initial price of $64.79, a miniature circular saw with an initial price of $45.99, and a screwdriver set with an initial price of $37.39. After applying the changes, the total cost of purchasing one of each item is $3.77 more than it was before applying the changes. Which item was marked down?

a.
power drill
b.
ceiling fan
c.
circular saw
d.
screwdriver set

Answers

Answer:

correct answer is option b.

Step-by-step explanation:

so Ashley has markdown one item by 15%

and mark up other items by 10% to get $3.77

assuming she marked ceiling fan mark down by 15%

if each  item is sold

  =  0.85 ×  $64.79 +1.1 × $51.49 +1.1 ×  $45.99 + 1.1 × $37.39

  = $203.4285

profit

= $203.4285 - $64.79 -$51.49 - $45.99 -$37.39

=$3.7685   ≅$3.77

hence ceiling fan price will be draw down by 15%

hence correct answer is option b.

The item that was marked down was the b. ceiling fan, from $64.79 to $55.07.

What are markdown and markup?

A markdown reduces the cost or price of an item by the percentage markdown.

A markup, on the other hand, increases the cost of the item.

Data and Calculations:

Markdown = 15%

Markup = 10%

Items                   Prices

Power drill          $51.49

Ceiling fan           64.79

Circular saw        45.99

Screwdriver set   37.39

Total price       $199.66

Increase in the price = $3.77

New price = $203.43 ($199.66 + $3.77)

Decision:

Most likely, Ashley will mark down the Ceiling fan to attract customers to purchase other items.

Therefore, the new prices after applying the changes will be:

Items                   Prices    Markup/down

Power drill          $51.49      $56.64 ($51.49 x 1.1)

Ceiling fan           64.79        55.07 ($64.79 x 0.85)

Circular saw        45.99       50.59 ($45.99 x 1.1)

Screwdriver set   37.39         41.13 ($37.39 x 1.1)

Total price       $199.66  $203.43

Comparison of new total price with old total price:

New total price = $203.43

Old total price = $199.66

Increase in cost = $3.77 ($203.43 - $199.66)

Thus, the item that was marked down was the b. ceiling fan.
