The area of a parallelogram is the base times the height so:

A=bh, in this case:

A=hx

x=A/h, we are told that A=120mm^2 and h=10mm so

x=120mm^2/10mm

x=12mm

Pepsi [2]

Answer:

x =  63°

y  = 45°

z = 72°

Step-by-step explanation:

<u>Points to remember</u>

1).  Opposite angles of a parallelogram are equal

2). Adjacent angles of a parallelogram are supplementary

3). Sum of angles of a triangle is 180°

<u>To find the measures of given angles</u>

ABCD is parallelogram.

m<C = m<C = x =  63°

Consider triangle  ABD

m<A + m< B + m<D = 180

x + 72 + y = 180

y = 180 - ( 72 + x) = 180 - 135

y  = 45°

Also y + z + m<C = 180

45 + z + 63 = 180

z = 180 - 108

z = 72°

Reaner Recycling collected 7/4 ton of aluminum last Saturday. If 7/8 ton of aluminum can be shredded each day, how many days wil
igor_vitrenko [27]

Answer:

2 days

Step-by-step explanation:

You would have to change 7/4 to have the same common denominator as 7/8, which is 8. 7/4 is equal to 14/8, or 1 6/8. Then you would subtract 1 6/8 by 7/8. What would be left would be 7/8. And of course, 7/8 minus 7/8 would be 0.

Hope this help you

(4x4 + 7x2 + 6x) - (x3 - 7x + 10)
stellarik [79]

Answer:

4x4 - x3 + 7x2 + 13x - 10

Step-by-step explanation:

(((4•(x4))+7x2)+6x)-(x3-7x+10)

((22x4 +  7x2) +  6x) -  (x3 - 7x + 10)

3.1    Find roots (zeroes) of :       F(x) = 4x4-x3+7x2+13x-10

Polynomial Roots Calculator is a set of methods aimed at finding values of  x  for which   F(x)=0  

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  x  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  4  and the Trailing Constant is  -10.  

of the Leading Coefficient :  1,2 ,4  

of the Trailing Constant :  1 ,2 ,5 ,10

Final result :

 4x4 - x3 + 7x2 + 13x - 10

hope this helps:)sorry if it doesnt

I NEED HELP ASAP write an equivalent unit rate to running 5/4 a mile in 9 minutes
svetlana [45]

Answer:

The unit rate is 0. 14 miles per minute.

Hence, option a is correct.

Step-by-step explanation:

Given

Running of 5/4 a mile in 9 minutes.

To determine

The unit rate = ?

Given that the running 5/4 a mile in 9 minutes.

i.e.

Miles covered in 9 minutes = 5/4 or 1.25 miles

Miles covered in 1 minute = 1.25/9

                                           = 0. 14 miles per minute

Therefore, we conclude that:

The unit rate is 0. 14 miles per minute.

Hence, option a is correct.
