A diver in the Olympics dives off a platform 15 m above the water’s surface and descends to a depth of 5 m below the surface. How many meters are traveled by the diver during the dive ?

Answers

Let the water surface be 0.

He starts at 15 and gets to the water surface of 0 so he travels 15 meters.

He then goes 5 meters below the surface.

15 + 5 = 20 total meters.

Answer:

20m

Step-by-step explanation:

the diver starts on a platform 15m above the water surface, which we will call 0. if he goes from the platform to -5m under the water, then he would have traveled 20m.

A circle has a radius of 5 ft. What is the area​

Answers

Answer:

78.5 ft²

Step-by-step explanation:

The area of a circle is given by

Area = πr²

where r is the radius = given as 5 ft

π = 3.14

substituting the values into the equation, we get

Area

= πr²

= (3.14) (5²)

= 78.5 ft²

Answer:

Solution :

Here, we have given that the radius of circle is 5 ft.

So, finding the area of circle by substituting the values in the formula :

[tex]\longrightarrow{\pmb{\frak{Area_{(Circle)} = \pi{r}^{2} }}}[/tex]

[tex]\longrightarrow{\frak{Area_{(Circle)} = 3.14 \times {(5)}^{2}}}[/tex]

[tex]\longrightarrow{\frak{Area_{(Circle)} = \dfrac{314}{100} \times {(5 \times 5)}}}[/tex]

[tex]\longrightarrow{\frak{Area_{(Circle)} = \dfrac{314}{100} \times {(25)}}}[/tex]

[tex]\longrightarrow{\frak{Area_{(Circle)} = \dfrac{314}{100} \times 25}}[/tex]

[tex]\longrightarrow{\frak{Area_{(Circle)} = \dfrac{314 \times 25}{100}}}[/tex]

[tex]\longrightarrow{\frak{Area_{(Circle)} = \dfrac{7850}{100}}}[/tex]

[tex]\longrightarrow{\frak{Area_{(Circle)} = 78.50 \: {ft}^{2} }}[/tex]

[tex]\star \: {\underline{\boxed{\sf{\purple{Area_{(Circle)} = 78.50 \: {ft}^{2}}}}}}[/tex]

Hence, the area of circle is 70.50 ft².

Calculate the volume of the prism by first finding the total number of half-unit cubes that will fill it. There are 8 half-unit cubes in every unit cube.

Answers

Answer:

10 half unit cubes

Volume = 1 1/4 unit³

Step-by-step explanation:

Volume of rectangular prism = Length * width * height

From the dimensions given in the picture :

Volume = 1 * 1/2 * 2 1/2

Volume = 1 * 1/2 * 5/2

Volume = 5/4 unit³

Volume = 1 1/4 unit³

Number of half unit cube per unit³ = 8

Total number of half unit cubes that will fill it:

Number of half unit cube per unit³ * volume

8 * 5/4

= 40 /4

= 10

An artist is creating a structure for the bull by store in the shape of sphere the sculpture will be filled with it seem it and has a diameter of 24 inches use to approximate the volume of sculpture in cubic inches to the nearest hundredth

Answers

Answer:

[tex]V=7238.22\ \text{inches}^3[/tex]

Step-by-step explanation:

The diameter of a sphere, d = 24 inches

Radius, r = 12 inches

We need to find the volume of sculpture which is in the shape of sphere. The formula for the volume of a sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3\\\\V=\dfrac{4}{3}\pi \times (12)^3\\\\V=7238.22\ \text{inches}^3[/tex]

So, the volume of the sculpture is [tex]7238.22\ \text{inches}^3[/tex].

Mia invested $52,000 in an account paying an interest rate of 3.1% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest tenth of a year, for the value of the account to reach $62,100?

Answers

Answer:

about 6 years 3 months

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.1%/100 = 0.031 per year,

then, solving our equation

t = 10100 / ( 52000 × 0.031 ) = 6.2655

t = 6.2655 years

The time required to

accumulate simple interest of $ 10,100.00

from a principal of $ 52,000.00

at an interest rate of 3.1% per year

is 6.2655 years (about 6 years 3 months).

Step-by-step explanation:

[tex](-3x^{2}+6x-12)+(5x+9) = -3x^{2} + 6x - 12 + 5x + 9 = -3x^{2} + 11x - 3[/tex]

Answer:

see below

Step-by-step explanation:

Here are the simplified results of each polynomial combination.

(5x2 + 2x + 1) + (6x2 − 3x + 9)

= 5x2 + 2x + 1 + 6x2 − 3x + 9

= 5x2 + 6x2 + 2x − 3x + 1 + 9

= 11x2 − x + 10 (B)

(-3x2 + 6x − 12) + (5x + 9)

= -3x2 + 6x − 12 + 5x + 9

= -3x2 + 6x + 5x − 12 + 9

= -3x2 + 11x − 3 (A)

(8x + 16) − (3x2 − 3x − 15)

= 8x + 16 − 3x2 + 3x + 15

= -3x2 + 8x + 3x + 16 + 15

= -3x2 + 11x + 31 (D)

(5x2 + 23x − 7) − (x2 − 4x + 21)

= 5x2 + 23x − 7 − x2 + 4x − 21

= 5x2 − x2 + 23x + 4x − 7 − 21

= 4x2 + 27x − 28 (C)

Ludwig the cow has decided to build a rectangular fence around his part of a pasture because Gustav the goat thinks he is cool and can eat all the grass he wants, including the grass on Ludwig’s side of the pasture. Ludwig determines that the perimeter of the fence has to be greater than 132 yards. If Ludwig needs the width of the fence to be eight less than the length, determine, to the nearest whole yard, the smallest the length of the fence can be and still have a perimeter greater than 132 yards.

Answers

9514 1404 393

Answer:

  38 yards

Step-by-step explanation:

Let x represent the length and y the width, both in yards. Then the required relations are ...

  2(x+y) > 132 . . . . . . the perimeter is greater than 132 yards

  y = x - 8 . . . . . . . . . . width is 8 less than length

Substituting for y in the first equation gives ...

  2(x +(x -8)) > 132

  4x -16 > 132

  x -4 > 33

  x > 37

The smallest length the fence can be is 38 yards.

__

Check

At that length, the width is 30 yards, and the perimeter is 2(38+30) = 136 yards. If the length were 37 yards, the perimeter would be 132 yards, which is not greater than 132 yards.
