Answer:

Yes

Step-by-step explanation:

if you think of a slope equation, for example y= 3x + 2, if you do the opposite reciprocal, you would get-1/3 because you flip it around, and you flip the sign.

Find the measure of acute angle of a right angle triangle when one angle is 60°

Pachacha [2.7K]

Answer:

30 degrees.

Step-by-step explanation:

Let the acute angle be x.

Then as the 2 acute angles in a right triangle sum to 90 degrees,

x = 90 - 60

= 30.

hodyreva [135]

Answer:

$16a^2b^4$

Step-by-step explanation:

<u>GCF= Greatest Common Factor</u>

Given a polynomial, the GCF is the largest polynomial that will divide evenly into that polynomial.

The polynomial is

$16a^4b^4 + 32a^3b^5 - 48a^2b^6$

First, we find the GCF of the coefficients:

16, 32, 48

Since 32 and 48 are multiples of 16, 16 is the GCF of the coefficients.

Now we select all the repeating variables with their smallest exponent:

$a^4, a^3, a^2.\ GCF= a^2$

$b^4, b^5, b^6.\ GCF=b^4$

The GCF of the polynomial is

$\boxed{16a^2b^4}$

Mrs. Child bakes pumpkin pies using a deep‐dish pie plate with a 9 inch diameter. If she cuts her pies into 12 equal slices and

andrew11 [14]

Answer: $4.71\ in.$

Step-by-step explanation:

Given

diameter of pie is $d=9\ inch$

radius $r=\frac{9}{2}=4.5\ inch$

If child divides pie into 12 equal parts then each part subtends an angle of

$=\frac{360^{\circ}}{12}=30^{\circ}$ at the center

and crust length of single piece is

$=\frac{30}{360}\times 2\pi r$

$=\frac{1}{12}\times 2\times \pi \times 4.5$

$=2.35\ in.$

For two slice length is $2\times 2.35=4.71\ in.$

Thus the total length of crust eaten is $=4.71\ in.$
