Mathematics
1 answer:
Juliette [100K]3 years ago
3 0

Answer:

Option (A) and Option (E)

Step-by-step explanation:

Length of a segment between two points (x_1,y_1) and (x_2,y_2) is given by,

Length = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}

Length of the segment between J(-8, 1) and K(-5, 5) will be,

JK = \sqrt{(-8+5)^2+(1-5)^2}

JK = \sqrt{9+16}

JK = 5 units

Length of segment between the points P(2, 8) and Q(7, 3) will be,

PQ = \sqrt{(2-7)^2+(8-3)^2}

PQ = \sqrt{25+25}

PQ = 5\sqrt{2} units

Length of segment between the points S(-3, -10) and T(3, -2) will be,

ST = \sqrt{(-3-3)^2+(-10+2)^2}

ST = \sqrt{36+64}

ST = 10 units

Therefore, Option (A) and Option (E) are the correct options.

What is the surface area of this composite solid?______________ square feet 242 319 363 517
jeka57 [31]

Answer:

<h2>The right answer is 415.4 cubic feet.</h2>

Step-by-step explanation:

As you can observe in the image attached, the composite figure is formed by a square prism and a pyramid on top.

We need to find the volum of each part separately.

<h3> Square prism.</h3>

V_{prims}=11 \times 11 \times 2=242 \ ft^{3}

<h3>Square pyramid.</h3>

First, we need to find the height of the pyramid. We already know the height of each triangular face of the pyramid, which divides equally the side.

Let's use Pythagorean's Theorem to find the height of the pyramid.

7^{2}=h^{2} +(5.5)^{2}\\  49-30.25=h^{2}\\ h=\sqrt{18.75} \approx 4.3

The height is 4.3 feet, approximately.

Now, we find the volume of the pyramid

V_{pyramid}=\frac{1}{3}(11 \times 11 \times 4.3) \approx 173.4ft^{3}

The sum of both figures represents the total volume of the composite figure

V_{total}=242+173.4=415.4ft^{3}

Therefore, the right answer is 415.4 cubic feet.

On a certain hot summer day, 673 people used the public swimming pool. The daily prices are 1.75 for children and 2.00 for adult
amid [387]

Answer:

Number of children = 386

Number of adults = 287

Step-by-step explanation:

Let

x = number of children

y = number of adults

x + y = 673 (1)

1.75x + 2y = 1249.50 (2)

From (1)

x = 673 - y

Substitute x = 673 - y into (2)

1.75x + 2y = 1249.50

1.75(673 - y) + 2y = 1249.50

1177.75 - 1.75y + 2y = 1249.50

- 1.75y + 2y = 1249.50 - 1177.75

0.25y = 71.75

y = 71.75/0.25

y = 287

Substitute y = 287 into (1)

x + y = 673

x + 287 = 673

x = 673 - 287

x = 386

Number of children = 386

Number of adults = 287

A plane ride lasted 6.4 hours. how many seconds did the plane ride last
ladessa [460]

1 * 60 * 60 = 3600 (seconds in 1 hour)

3600 * 6 = 21600 (seconds in 6 hours)

3600 * 0.4 = 1440 (seconds in 0.4 hour)

21600 + 1440 = 23040 (6 hours + 0.4 hours)

your answer is 23040
