Please Find H And A

Answers

Answer 1

Answer:

h=12 + c=20

Step-by-step explanation:

a^2+b^2=c^2

9^2+h^2=15^2

15^2-9^2=h^2

225-81=h^2

144=h^2

[tex]\sqrt{144}[/tex] = h

12=h

a^2+b^2=c^2

16^2 + 12^2 = c^2

256+144=c^2

400=c^2

[tex]\sqrt{400}[/tex] = c

20=c

Solve for a.

a + (−5) = 12

Answers

Answer:

a = 17

Step-by-step explanation:

a + (-5) = 12

Open the bracket;

a - 5 = 12

Add 5 to both sides

a - 5 + 5 = 12 + 5

Therefore,

a = 17

Answer:

a=17

Step-by-step explanation:

any number plus a negative number is basically subtracting the absolute value of the negative number. so 12 + 5 = 17

Answer:

The height is 15 cm. The volume is 6000 cm³

Step-by-step explanation:

The base is square, so the sides are equal.

√400 = 20. This is the length and width of the cuboid.

The area of the base and the area of the top face are equal, so we subtract 2(400) from the total area to get the area of the remaining 4 faces.

2000 - 800 = 1200 cm²

Divide by 4 to get the area of an individual face.

1200/4 = 300 cm²

We found the width earlier: 20cm

We found the width earlier: 20cm300/20 = 15cm. This is the height.

To find Volume, multiply Area of the base times the height:

400cm²×15cm = 6000cm³

Coach Pettaway is buying basketball equipment for his team. He gets a
reduced rate if he buys 8 basketballs for every 3 jerseys. The reduced rate is $2.25
per basketball and $22.50 per jersey. The sales tax on each item is 6%. Coach
Pettaway has $400 in his budget to buy the basketballs and jerseys. What is the
greatest number of basketballs and jerseys he can buy at the reduced rate if the
ratio of basketballs to jerseys is 8:32 Show your work.

Answers

First, let’s all acknowledge that whoever comes up with problems like this WANTS kids to hate math...smh

I’m sure there is a prettier way to solve this, but here’s what I did:

8(2.25) + 3(22.50) =
18 + 67.50 = 85.50 per “set” of balls/jerseys
400/85.50 = 4.678 = number of “sets” he can buy. Round down to 4 so we have room for tax.

85.5 x 4 “sets”= $342
Tax on 342 is 0.06 x 342 = 20.52

$342 + 20.52 = $362.52 spent

Basketballs = 4 sets x 8 balls per set= 32
Jerseys = 4 sets x 3 jerseys per set= 12

32 basketballs, 12 jerseys, $362.52 spent

Answer:

43 Degrees

Step-by-step explanation:

(3x + 16) + (6x + 1) + (82) = 180 Degrees

180 - 82 = 98 Degrees

(3x + 16) + (6x + 1) = 9x + 17

9x + 17 = 98

98 - 17 = 81

81 / 9 = 9

x = 9

6(9) + 1 = 55 Degrees

3(9) + 16 = 43 Degrees

55 + 43 + 82 = 180 Degrees

Kelli is searching for a new daycare center for her child. At Lori's Local Daycare, there is a ratio of 2 caretakers for every 7 children. If there are 189 total children, then how many people are at the daycare facility?

Answers

Answer:

243 people

Step-by-step explanation:

Kelli is searching for a new daycare center for her child. At Lori's Local Daycare, there is a ratio of 2 caretakers for every 7 children. If there are 189 total children, then how many people are at the daycare facility?

The ratio is given as:

Caretakers : Children

2 : 7

= In fraction = 2/7

If there are 189 total children, then how many people are at the daycare facility?

Step 1

We calculate the number of caretakers is there are 189 children

7 children = 2 caretakeras

189 children = x

Cross Multiply

7x = 189 × 2

x = 189 × 2/7

x = 54 caretakers

Step 2

The total number of people at the daycare

= 189 children + 54 caretakers

= 243 people

A rectangular garden is 5m longer
than it is wide.
The area of the garden is 600m2
Calculate the width and length of the garden.​

Answers

Answer:

The width of the garden is 22.12 m and its length is 27.12 m

Step-by-step explanation:

Equations

Let x = width of the garden

The length is 5 m longer than the wide, thus:

x + 5 = length of the garden

The area of the rectangular garden is

A=x(x+5)=600

Operating:

[tex]x^2+5x-600=0[/tex]

Solving with the quadratic formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Where a=1 b=5 c=-600:

[tex]\displaystyle x=\frac{-5\pm \sqrt{5^2-4(1)(-600)}}{2(1)}[/tex]

Operating:

[tex]\displaystyle x=\frac{-5\pm \sqrt{25+2400}}{2}[/tex]

[tex]\displaystyle x=\frac{-5\pm \sqrt{2425}}{2}[/tex]

There are two solutions:

x = 22.12

x = -27.12

The negative solution is not valid because x is the width of the garden, thus

x = 22.12 m

And

y = 22.12 + 5 = 27.12 m

The width of the garden is 22.12 m and its length is 27.12 m

A coin purse contains d dimes and q quarters. There are 35 coins in the purse, and the total value of the coins is $5.60. Create the system of linear equations and use it to find how many dimes and quarters are in the purse.

Answers

Answer:

14 dimes, 21 quarters

Step-by-step explanation:

Represent dimes with d and quarters with q.

So: 35 coins means

[tex]d + q = 35[/tex]

1 dime = $0.10 and 1 quarter = $0.25. So, a value of $5.60 means

[tex]0.10d + 0.25q = 5.60[/tex]

So, the system of equations is:

[tex]d + q = 35[/tex]

[tex]0.10d + 0.25q = 5.60[/tex]

Make d the subject in [tex]d + q = 35[/tex]

[tex]d = 35 - q[/tex]

Substitute 35 - q for d in [tex]0.10d + 0.25q = 5.60[/tex]

[tex]0.10d + 0.25(35 - q) = 5.60[/tex]

Open bracket

[tex]0.10d + 8.75 - 0.25q = 5.60[/tex]

Collect Like Terms

[tex]0.10d - 0.25q = 5.60 - 8.75[/tex]

[tex]-0.15q = -3.15[/tex]

Solve for q

[tex]q = \frac{-3.15}{-0.15}[/tex]

[tex]q = 21[/tex]

Substitute 21 for q in [tex]d = 35 - q[/tex]

[tex]d = 35 - 21[/tex]

[tex]d = 14[/tex]

Please answer question quickly!here is the story: Some of the earliest lighthouses were simply hillside bonfires. Today, a lighthouse is commonly known as a type of tower that shines a large lamp out to the sea. The light helps to mark dangerous areas along a coast. A lighthouse also gives notice to a ship that land is near. Many lighthouses were constructed in the 17th century. The first lighthouse in the U.S. was built in 1716 in Boston Harbor. Nearly 1,000 lighthouses were built by 1900 in the U.S. After this point, many lighthouses were abandoned and became rundown as a result. In the U.S., the coast guard oversees the lenses and lamps of the countrys lighthouses. In more recent years, the destruction of lighthouses has been rising. Groups have formed in order to restore lighthouses. Often, these lighthouses are made into parks, museums, research centers, and even inns or hotels to stay at overnight.and here is the question: Groups that restore lighthouses would most likely agree with which of the following? A. Lighthouses should all be restored so they are the same size and shape. B. Lighthouses are an important part of history that should be preserved. C. Lighthouses are no longer useful with today's computerized technology. D. Lighthouses should be owned and operated by the national government. Heres the poem for the last assignment I posted.
