Perpendicular lines AB and CD Intersect at point E. If m<AED=×+20, wha is the value of x

vladimir1956 [14]

Answer:

x = 70°

Step-by-step explanation:

Itz given that AB & CD are perpendicular to each other and intersect at E . So , angle(AED) = 90°

But here the value of angle(AED) = 90°

So,

x + 20 = 90°

=> x = 90° - 20°

= 70°

The coordinate grid shows points A through K. What point is a solution to the system of inequalities? y ≤ −2x + 10 y > 1 over

vlabodo [156]

Answer:

A, C, D and K

Step-by-step explanation:

First, plot the solution set to the system of two inequalities.

The inequality $y\le -2x+10$ determines solid line and bottom shaded region under this line.

The inequality $y>\dfrac{1}{2}x-2$ determines dotted line and top shaded region under this line.

The intersection of these two regions is the solution set to the system of two inequalities.

Points A, C, D and K belong to this region.

What is the value of x to the power of 6 + y to the power of 2 when x=1 and y=11

siniylev [52]

Answer: 122

Step-by-step explanation: Substitute the values of x and y into the expression.

$x^6+y^2 \\ \text{ is like } \\ ( )^6 + ( )^2$

"Fill in the blanks" with the numbers given for x and y.

$(1)^6+(11)^2 = 1+121=122$

Find the volume of the cylinder in terms of pi.

Allushta [10]

Answer:

$\large\boxed{V=81\pi\ in^3}$

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

We have r = 3in and H = 9in. Substitue:

$V=\pi(3^2)(9)=\pi(9)(9)=81\pi\ in^3$
