a rectangular field is 45 feet wide and is enclosed by 210 feet of fencing what is the area of the field in square feet

1 answer:

7 0

Find the length of the field first. To do this, write a formula for the perimeter, P, of the field: P = 210 ft = 2(45 ft) + 2L.

Then 2L = 210 - 90 = 120, and L = 60 (feet).

The area of the field is thus WL = (45 ft)(60 ft) = 2700 sq ft

Can someone give me the answer and how you work this? -5 - (-10) = ?

erastovalidia [21]

Answer:

Step-by-step explanation:

-5 - (-10)

Here we have to use sign of multiplication rule.

negative * negative = positive

that is, -(-) = +

We use this rule and simplify.

- (-10) = + 10

Therefore, -5 + 10

When we have different sign of the numbers, we have to subtract from greatest to least number, then put the largest number sign in the answer.

-5 + 10 = + 5

Hence, the answer is 5

Hope this is will help you.

Thank you.

Answer:

>180° (more than 180°)

Step-by-step explanation:

Angles are classified as ...

acute: < 90°
right: = 90°
obtuse: > 90°
straight/linear: = 180°
reflex: > 180°

It seems that we're looking at definitions:

obtuse : >90° :: reflex : >180°

Answer:

1.) $=\frac{\sqrt{3}}{3}$

2.) $42\sqrt{30}$

Step-by-step explanation:

1.) $\mathrm{Multiply\:by\:the\:conjugate}\:\frac{\sqrt{3}}{\sqrt{3}}$

2.) $\mathrm{Apply\:radical\:rule}:\quad \sqrt{a}\sqrt{b}=\sqrt{a\cdot b}$

$\sqrt{6}\sqrt{5}=\sqrt{6\cdot \:5}$

In one baseball season, Nolan hit twice the difference of the number of home runs Mrs. Davis hit and 6. Altogether, they hit 18

Alborosie

Answer:

Nolan hitted 8 home runs

Step-by-step explanation:

Let's call the number of home runs that Nolan hitted by N, and that Davis hitted by D.

So, we can write the following equations:

N = 2 * (D - 6)

N + D = 18

Now we can solve the system of equations, using the value of N from the first equation in the second one:

2 * (D - 6) + D = 18

2*D - 12 + D = 18

3*D = 30

D = 10

Now we find N:

N + D = 18

N + 10 = 18

N = 8

So we have that Nolan hitted 8 home runs.
