x = 50°

Step-by-step explanation:

triangles add to 180 degrees

180 = 110 + 20 + x

180 = 130 + x

-130

x = 50°

Answer:

50°

Explanation

Since we know that a triangle is made up of $180$ ° we can make an equation,

$x+110+20=180$

solve it and we get that

$x=50$ °

Ariel is filling a giant beach ball with air. The radius of the beach ball is 303030 cm. What is the volume of air that the beac

AVprozaik [17]

Answer:

The volume of air that the beach ball will hold is $36,000 \pi\ cm^{3}$

Step-by-step explanation:

we know that

The volume of a sphere ( a giant beach ball with air) is equal to

$V=\frac{4}{3}\pi r^{3}$

we have

$r=30\ cm$

$V=\frac{4}{3}\pi (30^{3})$

$V=36,000 \pi\ cm^{3}$

Solve the inequality and show your solution on a number line: 0.2x−2<7−8x

Allisa [31]

Answer:

$x< \frac{45}{41}$ or $x< 1.098$

The graph in the attached figure

Step-by-step explanation:

we have

$0.2x-2 < 7-8x$

Solve for x

Adds 2 both sides

$0.2x-2+2 < 7-8x+2$

$0.2x < 9-8x$

Adds 8x both sides

$0.2x+8x < 9-8x+8x$

$8.2x < 9$

Divide by 8.2 both sides

$x < 9/8.2$

Remember that

$8.2=82/10$

substitute

$x < 9/(82/10)$

$x< \frac{90}{82}$

Simplify

$x< \frac{45}{41}$ or $x< 1.098$

The solution is the interval ------> (-∞, 45/41)

All real numbers less than 45/41

In a number line , the solution is the shaded area at left of x=45/41 (open circle)

Helpppp I will give BRAINLY just please help

MAXImum [283]

Answer:

$\Huge\boxed{x=12}$

Step-by-step explanation:

Hello There!

The following angles are complementary angles

Complementary angles have a sum of 90

So to solve for the variable (x) we use this equation

90 = 35 + 4x + 7

step 1 combine like terms

35+7=42

now we have

90 = 4x + 42

step 2 subtract 42 from each side

90 - 42 = 48

42 - 42 cancels out

now we have

48 = 4x

step 3 divide each side by 4

4x/4 = x

48 / 4 = 12

we're left with x=12
