Is a 78 degree angle a right,straight,obtuse or acute angle

Answers

Answer 1
Answer: Acute. 90 degrees is a right angle, 180 degrees is a straight angle, obtuse angles are greater than 90 degrees, while acute are less than 90 degrees.
Answer 2
Answer: Acute because it is less than 90o which is a right angle and obtuse is larger than 90o so there for it is acute angle which is less than 90o

Brady buys 3 gallons of fertilizer for his lawn. after he finishes spraying the lawn he has 1 quart of fertilizer left over. how many quarts of fertilizer did Brady spray on the lawn?

Answers

Answer: Brady sprayed 11 quarts of fertilizer

Step-by-step explanation:

Given : Brady buys 3 gallons of fertilizer for his lawn.

Since 1 gallon = 4 quarts

Then, 3 gallons = 4*3=12\ \text{ quarts}

After he finishes spraying the lawn he has 1 quart of fertilizer left over.

Then, the number of quarts of fertilizer Brady sprayed on the lawn

= Quarts of fertilizer bought - Quarts of fertilizer left

=12-1=11 quarts

Hence, Brady sprayed 11 quarts of fertilizer .

Answer:

x^2-6x+7

Step-by-step explanation:

You can use synthetic division since you are dividing by a linear factor with leading coefficient 1.  (You can also do synthetic division when dividing by a linear factor whose leading coefficient is not 1 but it is a bit trickier.)

So since we are dividing by x-2, 2 goes on the outside.

(If we were dividing by x+2, -2 would go on the outside.)

Now the thing that goes on top inside is the dividend, the numerator which is 1x^3-8x^2+19x-14. If you were missing any terms you would have to place a zero but we aren't. All exponents between 3 and 0 (inclusive meaning to include the 3 and the constant term) on variable x is accounted for.  

2|  1   -8    19     -14

 |       2    -12      14

  -----------------------------

     1  -6     7       0

So the remainder is 0 and the quotient is x^2-6x+7.

What is the volume of the right rectangular prism?

The volume of a right rectangular prism (V) = l × w × h,

where

“l” is the base length

“w” is the base width

“h” is the height of the prism

Given,

Height of prism = 15mm

The Base area of prism = 49^2mm

As we know the formula of base area = lw

which equals to lw = 49^2mm

now, the volume of the right rectangular prism is = lwh

                                                                              =49*15 mm^3

                                                                              = 735mm^3

Answer:

735 mm³

Step-by-step explanation:

refer to attached picture

volume = lwh  

given: area of base = lw = 49 mm²

hence formula can be re-written

volume = (area of base) x h

= 49 x 15

= 735 mm³

What are 2 numbers that when multiplied together you get 360 and when added together you get -96

Answers

x + y = -96;
x * y = 360;

t^(2) + 96t + 720 = 0;
Δ = 96^(2) - 4 * 720 = 6336 => sqrt(Δ) = 79.6;
=> x = ( - b +  sqrt(Δ) ) / 2a => x = ( -96 + 79.6 ) / 2 ≈ - 8.2;
=> y =  ( - b -  sqrt(Δ) ) / 2a => x = ( -96 - 79.6 ) / 2 ≈ - 87.8;

A box has a length of 15 in., a width of 7 in., and a height of 9 in. If Tara plans to cover the box with wrapping paper, how much wrapping paper will she need?

Answers

We have to calculate the area of the box.

area (box)=2(lenght x width) + 2(lenght x height) +2(width x height)

area (box)=2(15 in x 7 in) + 2(15 in x 9 in) + 2(7 in x 9 in)=
=2(105 in²)+2(135 in²)+2(63 in³)=210 in²+270 in²+126 in²=606 in².

Answer: she need 606 in² of wrapping paper.
