which expression has the least value when x=100?
A.1/x
b.10/x
c.1-x
D 10-x​

Answers

Answer:

C

Step-by-step explanation:

C will have the least value with -99.

A would be 1/100, which is 0.01, which is small, but larger than -99.

B would be 10/100, which is 0.1, which is larger than A.

C is 1-100, which equals -99.

D is 10-100, which equals -90. -99 is smaller than -90.

Answer:

c) 1 - x

Step-by-step explanation:

x = 100

a) [tex]\frac{1}{x}[/tex] ⇒ [tex]\frac{1}{100}[/tex]

answer ⇒ 0.01

b) [tex]\frac{10}{x}[/tex] ⇒ [tex]\frac{10}{100}[/tex]

answer ⇒ 0.10

c) 1 - x ⇒ 1 - 100

answer ⇒ -99

d) 10 - x ⇒ 10 - 100

Given circle B below, find the value of x.

(3x + 10)
(2x - 17)

Answers

Answer: 44

Step-by-step explanation:

since the inscribed angle is half of true arc measure, (3x+10)= 2(2x-17).

when you work this out, you get 44 as x.

The value of x from the given figure is 44°. Therefore, option B is the correct answer.

What is relation between angle at the center and the angle at the circumference?

The angle subtended by an arc at the center is twice the angle subtended at the circumference . More simply, the angle at the center is double the angle at the circumference.

From the given figure,

Angle at circumference is (2x-17)° and angle at center is (3x+10)°.

Now, (3x+10)°=2(2x-17)°

3x+10=4x-34

4x-3x=10+34

x=44°

Therefore, option B is the correct answer.

Step-by-step explanation:

≥ means that it is greater than or equal to.

Any set that has all numbers over or equal to -5 would be correct, meaning that -5, -4.5, and -3 would be correct.

Hope this helps. Have a nice day.

Inequalities help us to compare two unequal expressions. The set of values makes the inequality n > -5 true is {-5, -4.5, -3}.

What are inequalities?

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.

It is mostly denoted by the symbol <, >, ≤, and ≥.

As we need to find the values that will satisfy the inequality n≥-5, therefore, we need values that are greater than or equal to -5.

Hence, the set of values makes the inequality n > -5 true is {-5, -4.5, -3}.

Answers

Answer:

D. 13,000

Step-by-step explanation:

If there are 1,000 m in 1 km, we can find the number of meters she hiked by multiplying 13 by 1,000:

13(1000)

= 13,000

So, Belle hiked 13,000 meters.

The measurement 345.58 cm² is the closest to the total surface area of the can in square centimeters.

The correct option is A.

What is a cylinder?

A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.

Given:

A can in the shape of a cylinder has a diameter of 10 centimeters and a height of 6 centimeters.

The surface area of the cylinder,

= 2π r h + 2π r²

= 2 (3.14)(5)(6) + 2 (3.14) (25)

= 345.4 square centimeters.

Therefore, 345.58 cm² is the closest value.

a system with no solutions

Answers

Answer:

[see below]

Step-by-step explanation:

A system of equations with no solution would show parallel  lines. We just have make a equation that is parallel to the original equation.

The slope of 2x + 8y = 12 is [tex]-\frac{1}{4}[/tex], and it's y-intercept is [tex]\frac{3}{2}[/tex].

Since parallel lines have the same slope but not the same y-intercept, I would use [tex]y=-\frac{1}{4}x+3[/tex].

Any equation that has -1/4 as the slope would work.  

When graphed together, they show as a system with no solution.

Answer: 120ft

Step-by-step explanation:

To work out the area of this composite shape you would have to work out the two shapes separately. The shape could be split into 2 rectangles.

The formula for the area of a rectangle is base x height.

So, to work out the area of the living room you have to do 15x7=105

Then to work out the area of the foyer, you would have to do 3x5=15

Because you want the area of both of the shapes together, you have to add the two areas of the rectangles together.

So 105+15=120

Answers

Answer:

$160

Step-by-step explanation:
