4/1=4

Answer:

5 inches

Step-by-step explanation:

Since the length irl is 60 yards you should divide 60 by 3.

60/3=20

Then convert 1/4 to a decimal.

1/4=0.25

Finally multiply 20 and 0.25 to get the length of the park on the map.

20x0.25=5

your answer is Option F 5 inches

Answer:

C

Step-by-step explanation:

Let the length be l and width be w.

The perimeter will be 2 lengths + 2 widths = 2l+2w

2l+2w cannot be more than 100ft

[tex]21+2w \leq 100[/tex]

Also, the length has to be at least 10ft longer than the width.

[tex]l\geq w+10[/tex]

If we substitute w=20, l=30. 2l+2w can be equal to 100 but not over it.

If w=20 and l=30, 2w+2l = 40+60 = 100.

Hence the maximum length of the width of the fence is 20 ft. C

Step-by-step explanation:

50d^2 - 98e^2

Factor out 2.

2(25d^2 - 49e^2)

We now factor the difference of two perfect squares within the parentheses.

2(5d - 7e)(5d + 7e)

This is as far as we can factor.

Done!

The factor of the expression into an equivalent form 50d²- 98e² would be;  2(5d - 7e)(5d + 7e)

Factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

We are given that expression is given that 50d²- 98e².

We have to Factorise .

Factor out 2.

Answer:

You have to use the Pythagorean Theorem to find the other side, which will be your base in the Area formula (A=1/2bh). So the Pythagorean theorem would be 36^2 + b^2 = 60^2. This gives you 48 in for your base/missing side length. Then, you plug it into the area formula. So, A=1/2(48) (36). This gives you 864 in^2 for the area of your triangle.

Answer:

X=18

Step-by-step explanation:

you can find what the missing angle is by subtracting 92 from 180 since its a straight line. After putting in the missing angle you can easily solve for 2X which is 36 and then divide by 2 and get 18.

Answer:

x = 23

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

92° is an exterior angle of the triangle, then

2x + 46 = 92 ( subtract 46 from both sides )

2x = 46 ( divide both sides by 2 )

x = 23
