What is the area of the figure?

A figure can be broken into 2 rectangles. One rectangle has a base of 7 and one-half feet and a height of 3 feet. The other rectangle has a base of 11 and one-half feet and height of 3 feet.

Answers

Answer 1

Answer: 57 ft²

Step-by-step explanation:

Find the areas of the two individual rectangles and then add that up to find the area of the figure:

Rectangle A:                                                             Rectangle B:

= Length * Width                                                       = 11.5 * 3

= 7.5 * 3                                                                     = 34.5ft²

= 22.5 ft²

Area of figure:

= 22.5 + 34.5

= 57 ft²

Answer 2

Answer:

I am 99.9% sure it is 57 square feet.

Answers

Answer:

B, D, and E

Step-by-step explanation:

B. Five hundred thousand = 500,000/ three hundred = 300/ sixty-eight = 68.

D. 5 hundred thousands = 500,000/ 3 hundreds = 300/ 6 tens = 60/ 8 ones = 8.

E. 500,000 + 300 + 60 + 8 = 500,368.

A rectangular box without a top is have a volume of 12 cubic feet. Find the dimensions of
the box that will have minimum surface area.​

Answers

If the length, breadth and height of the box is denoted by a, b and h respectively, then V=a×b×h =32, and so h=32/ab. Now we have to maximize the surface area (lateral and the bottom) A = (2ah+2bh)+ab =2h(a+b)+ab = [64(a+b)/ab]+ab =64[(1/b)+(1/a)]+ab.

We treat A as a function of the variables and b and equating its partial derivatives with respect to a and b to 0. This gives {-64/(a^2)}+b=0, which means b=64/a^2. Since A(a,b) is symmetric in a and b, partial differentiation with respect to b gives a=64/b^2, ==>a=64[(a^2)/64}^2 =(a^4)/64. From this we get a=0 or a^3=64, which has the only real solution a=4. From the above relations or by symmetry, we get b=0 or b=4. For a=0 or b=0, the value of V is 0 and so are inadmissible. For a=4=b, we get h=32/ab =32/16 = 2.

Therefore the box has length and breadth as 4 ft each and a height of 2 ft.

?oz:1/3.   How many oz does it take to cover 1/3 of the box?

0.4:1/3.   0.4oz is needed to cover 1/3 of the box.

1/3*3=1.    0.4*3=1.2  *= multiplication

I believe the answer Is: 1.2oz is needed to cover 1 box. The information here should help you the diagram.

Noah needs 1.2 ounces of paint to cover 1 box.

Given that Noah is painting boxes that are all the same size, and I have used 2 ounces of paint to cover 1 2/3 boxes, to determine how many ounces of paint are needed to cover 1 box, the following calculation must be performed:

1.666 = 2 1 = X 2 / 1,666 = X 1.2 = X

Therefore, Noah needs 1.2 ounces of paint to cover 1 box.

What is the image of (-9,0) after a reflection over the x-axis?

Answers

Answer:

(-9, 0)

Step-by-step explanation:

When a point is reflected over the x-axis, the x-coordinate stays the same but the y-coordinate turns into its opposite. So, the x-coordinate would stay as -9. Because zero is neither negative nor positive, it doesn't have an opposite. So, the y-coordinate would still be 0.

When playing the roulette at a casino, you have exactly 1/35 chance of winning in each round if you play a single number. Your friend has rigged up some fireworks to be set off when you win. When you win, he sets off the fireworks every time. When you don't win, he accidentally sets off the fireworks 10% of the time. If you failed to see the outcome of a round, but you see the fireworks going off, then what is the probability that you actually won that round?

Answers

Answer:

0.2275 = 22.75% probability that you actually won that round

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Fireworks going off

Event B: You won

Probability of fireworks going off.

100% of 1/35 = 0.0286(when you win)

10% of 34/35 = 0.9714(you lost). So

[tex]P(A) = 0.0286 + 0.1*0.9714 = 0.12574[/tex]

Probability of you winning and fireworks going off:

100% of 1/35, so [tex]P(A \cap B) = 0.0286[/tex]

If you failed to see the outcome of a round, but you see the fireworks going off, then what is the probability that you actually won that round?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0286}{0.12574} = 0.2275[/tex]

0.2275 = 22.75% probability that you actually won that round

Answers

Answer:

Step-by-step explanation:

Now e have two figures

1 is ABCD and other is APQD ,

Now to find g and f,

Now the are both figure is ,

Area = length * width

Area ABCD = 39 cm^2

AB* BC = 39

(g+7) * ( f) = 39

Again,

Area APQD = AP*QD= 16 cm ^2

(g)*(f)=16

from here f =16/g  putt it in above equation we get ,

(g+7)*16/g = 39

16*g-39*g+96 =0

-23g +96 = 0

g = 96/23

g =3 cm

Now for f putt in one of the above equation ,

f =16/3

f =5.33 cm

Answer:

f = 3cm g = 6cm

Step-by-step explanation: to find f

Subtract the area of APQD from ABCD then divide by 7

f = (39 - 18)/7

f = 21/7

f = 3

To find g, divide the area of APQD by 3

18/3 = 6

We can do this because of the givens: ABCD is a rectangle, PQ is parallel to AD, so BC=AD=PQ
