<u>Answer:</u>

$\simeq 820 feet$

<u>Step-by-step explanation:</u>

He has asked me to move the finish line 0.25 km forward

Now,

we know that

1 km = 0.621371 mile

⇒ 0.25 km = $0.25 \times 0.621371$ mile

= $0.25 \times 0.621371 \times 1760 \times 3$ feet

(since 1760 yards = 1 mile and 3 feet = 1 yard)

= 820.20972 feet

$\simeq 820 feet$ . (Answer)

Last month,Margo bought a tree that grows 2.5cm each day.It was 5cm tall when she bought it and now it 65cm tall. Write a equati

Effectus [21]

Answer:

The equation to determine the number of days Margo has owned the plant is $5+2.5x=65$ .

Step-by-step explanation:

Given:

Actual length of the tree = 5 cm

Current length of the tree = 65 cm

Per day growth Rate of plant = 2.5 cm

Let number of days she owned the plant be 'x'

Now We can say that,

Current length of the tree is equal to sum of Actual length of the tree and Per day growth Rate of plant multiplied by number of days she owned the plant.

Farming the above sentence in equation form we get;

$5+2.5x=65$

Hence the equation to determine the number of days Margo has owned the plant is $5+2.5x=65$ .

The radius of this ball is 15 inches. Which equation gives the ball's surface area, in square inches?

lilavasa [31]

Best to look up the formula for the surface area of a sphere and then find it:

A = 4πr^2, where r is the radius of the sphere. Then,

A = 4π(15 in)^2 = 4(3.14)(225 in^2) = 2826 in^2 (answer)

This is represented by the formula given in the lower left.

Answer:

w = 9.82

x = 66.73

Step-by-step explanation:

By applying tangent rule in triangle ABD,

tan(81°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

6.31 = $\frac{62}{w}$

w = $\frac{62}{6.31}$

w = 9.82

Similarly,

tan(39°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

0.81 = $\frac{62}{(x+w)}$

0.81 = $\frac{62}{9.83+x}$

9.82 + x = $\frac{62}{0.81}$

x = 76.56 - 9.82

x = 66.74
