Answer:

c=10

Step-by-step explanation:

pythagreom theroem

c (hypotenuse) = [tex]\sqrt{a^{2} +b^{2} }[/tex]

plug in values for a and b

c=[tex]\sqrt{6^{2} +8^{2} }[/tex]

c=[tex]\sqrt{36+64\\}[/tex]

c=[tex]\sqrt{100\\}[/tex]

c=10

Answer:

length of the hypotenuse = √100 = 10 ft

Step-by-step explanation:

This is a right triangle with leg lengths 6 and 8 ft.  We apply the Pythagorean Theorem a^2 + b^2 = c^2, as follows:

(6 ft)^2 + (8 ft)^2  = c^2

Then c^2 = 100, and c = length of the hypotenuse = √100 = 10 ft

Dado :

Miguel a cada 45 minutos

Nádia a cada 60 minutos

Número de horas que eles vão se ver no mesmo lugar:

Para fazer isso ;

Obtenha o menor múltiplo comum de 60 e 45

Múltiplos de:

45: 45, 90, 135, 180, 225.

60: 60, 120, 180, 240, 300.

O menor múltiplo comum de 45 e 60 é 180

° Assim, eles se verão no mesmo lugar após 180 minutos;

Número de horas = 180/60 = 3 horas

slope intercept y= 10x-82

Answer:

550 birds

Step-by-step explanation:

25% × 7 = 175%

100% + 175% = 275%

[tex]\frac{y}{200} :\frac{275}{100}[/tex]

y × 100 = 275 × 200

100y = 55000

100y ÷ 100 = 55000 ÷ 100

y = 550

Answer:

200*1.25ˣ

954

Step-by-step explanation:

let x= years

200*1.25ˣ = birds

plug in 7 for x

200*1.25⁷=953.6743164

round to 954

Given:

In the given cone,

Radius of the cone = 7.2 m

Slant height of the cone = 17 m

To find:

The surface area of the cone.

Solution:

The surface area of a cone is:

[tex]A=\pi rl+\pi r^2[/tex]

Where, r is the radius of the cone and l is the slant height of the cone.

Putting [tex]\pi=3.14,\ r=7.2,\ l=17[/tex] in the above formula, we get

[tex]A=(3.14)(7.2)(17)+(3.14)(7.2)^2[/tex]

[tex]A=384.336+162.7776[/tex]

[tex]A=547.1136[/tex]

[tex]A\approx 547.11[/tex]

Therefore, the surface area of the given cone is 547.11 square m.

Answer:

12.8

Step-by-step explanation:

Find the difference between 1.9 and 1.5 (Divide them)

You get 1.9 ÷ 1.5 = 1.26

Then multiply the answer with 8,

8 x 1.26 = 12.8 (Nearest tenth)

Answer:

Helen scores 10 points.

Step-by-step explanation:

We are given that for every 3 points Glenn scores, Helen scores 5 points. Glenn now scores 6 points and Helen's score is unknown. We can write this as a ratio.

Glenn - 3 : 5 - Helen

Glenn - 6 : ? - Helen

We can divide 6 by 3 to get the rate of change, which is 2. Then multiply 5 and 2 and we get 10! Helen scores 10 points for every 6 points Glenn scores. I hope this helps! :D

Answer:

The baseball was $8.79 without the shipping charge

Step-by-step explanation:

7% = 0.07

$9.45 * 0.07 = $0.6615

$9.45 - $%0.6615 = $8.7885

Hope this helps

Answer :

$8.7885 ($8.79) without shipping charge

Step by step Explanation :

I agree with the previous answer, you would find 7% of 9.45 first.

$9.45 * 0.07 = $0.6615

Then you would subtract because you want to find the cost of the baseball alone.  

$9.45 - $0.6615 = $8.7885

Answer:

416 ft

Step-by-step explanation:

We will start with the easiest shape.

10 x 4 x 4 = 160

We will put that to the side and continue.

we see that 20 feet is the whole height of the object but since there is the height of 4 feet on the bottom shape, we will take 4 from 20 to give us 16 feet for the top shape.

16 x 4 x 4 = 256

Now, we add the totals.

256 + 160 = 416

Answer:

416 ft

Step-by-step explanation:

We will start with the easiest shape.

10 x 4 x 4 = 160

We will put that to the side and continue.

we see that 20 feet is the whole height of the object but since there is the height of 4 feet on the bottom shape, we will take 4 from 20 to give us 16 feet for the top shape.

16 x 4 x 4 = 256

Now, we add the totals.

256 + 160 = 416

Answer:

19

Step-by-step explanation:

6×(6+14) = 5×(5+z)

120 = 25 + 5z

95 = 5z

z = 19

Answer:

Arc Length = 68.7

Step-by-step explanation:

The formula that is used to find the arc length:

s = (θ/360) * 2πr

(You would get the value of θ, by subtracting 57 from 360)

(You would get r by dividing 26 by 2)

Now we can solve this;

s = (303/360) 2π(13)

s = 0.842 * 2π(13)

s = 0.842 * 0.283(13)

s = 68.7

Hope this helps!
