Answer:

-4

Step-by-step explanation:

vertical opposite angles are equal

110=x+114

=-4+114

Answer:

-4 the answer is -4

x = 5 makes 2x≤ 10 true but not 2x < 10 because "≤" means less than or equal to, which means 2x would be the same as 10, so 10 ÷ 2 = 5, x = 5.

Answer:

Step-by-step explanation:

2x ≤ 10, when x = 5

2(5) ≤ 10

10 ≤ 10 (10 is less than OR equal to 10)

2x < 10, when x = 5

2(5) < 10

10 < 10 (10 is less than 10) - that is false

x = 5 does not makes 2x < 10 true because 10 can't be less than 10.

Answer:

16.2 = [tex]\frac{81}{5}[/tex] and 121 = [tex]\frac{121}{1}[/tex]

Step-by-step explanation:

16.2 can be simplified to its fraction form, which is [tex]\frac{81}{5}[/tex]

121 is already simplified since it is a whole number, but its fraction form would be [tex]\frac{121}{1}[/tex]

Answer:

Greater than for both i believe

Step-by-step explanation:

Answer:Yea both a greater than because if you do 2 x 5/2 it = 5 and 5 is a hole number 5/2 is not and 2 is a hole number but 5 is greater than 2.

Step-by-step explanation:

Answer:

Given that Elena is currently e years  old and Katie is k years old. Now, nine years ago, Katie was twice as old as Elena was.

So, k - 9 = 2(e - 9)

⇒ k - 2e + 9 = 0 .............. (1)

And, in four years, Elena will be as old as Katie is now.

So, k = e + 4

⇒ k - e - 4 = 0 ............... (2)

Therefore, the equations (1) and (2) matches the conditions. (Answer)

Answer:

74

Step-by-step explanation:

13 x 5 is 65. 65 + 9 is 74.

Answer:

74 Hours

Step-by-step explanation:

Knowing that Teresa worked for 13 hours each day for 5 days meaning

13 * 5 = 65.

Also known that the next day she working 9 hours.

Thus, 65 + 9 = 74

Hence, Teresa work 74 hour in all.

Step-by-step explanation:

The radius of cone = 9 cm

Step-by-step explanation:

Formula : Volume of a cone =  , where r= radius , h= height of the cone.

Given: Volume = 1,017.36 cubic centimeters

h = 12 centimeters

Substitute these values in formula , we get

Hence, the radius of cone = 9 cm

Answer:

Radius= 8.99 mm (9 mm)

Step-by-step explanation:

We use the formula for the volume of a cone which is

1/3 pi ×(radius)^2 *height

932.58 = (pi) × (11) ×(r^2/3)

Radius^2 = (932.58×3) / (11pi)

= 80.96m

Radius= 8.99mm

Answer:

volume= 1/3πr²h

932.58=1/3×3.14×r²×11

3×932.58=34.54×r² ×3

2,797.74 = 34.54×r²

34.54. 34.54

√r²= √81

r=9mm

Answer:

d 1/27

Step-by-step explanation:

Using the flip and multiply method:

      [tex]\sf \dfrac{1}{\dfrac{9}{3}}[/tex]

[tex]\sf \implies \dfrac19 \div 3[/tex]

[tex]\sf \implies \dfrac19 \div \dfrac31[/tex]

[tex]\sf \implies \dfrac{1 \times 1}{9 \times 3}[/tex]

[tex]\sf \implies \dfrac{1}{27}[/tex]

0The volume of fishtank A is 200 cubic feet, and the volume of fishtank B is 160 cubic feet. So fishtank A has a greater volume than Fishtank B.

Answer:

86.7

Step-by-step explanation:

L x W = 5.1 x 5.1 = 26.01
B x H ÷ 2 = 5.1 x 5.95÷2 = 15.1725
15.1725 x 4 = 60.69
60.69 + 26.01 = 86.7

The surface area of the  square pyramid is 92 square centimeters.

The given figure is a square pyramid.

We have to find the surface area.

Surface area = a² + 2a√(a²/4 + h²)

a is 5.1 cm and h is height which is 5.95 cm.

Surface area = 5.1² + 2(5.1)√(5.1²/4 + 5.95²)

=26.01 + 10.2 √(26.01 /4 +35.4025)

=26.01+10.2 √6.5025+35.4025

=26.01+10.2√41.905

=92 square centimeters.

Step-by-step explanation:

It is asking for 3 numbers greater than 0.39, with three in the tenth place (0.x000) that is less than 1. By adding a number in the thousandth place to 0.39, we automatically make it larger. Adding more digits will make it slightly larger, as long as it isn't a 0. All 4 answers I have provided are correct, however, I would just use the first 3 for your question.

Answer:

The answer is option C. 3

Step-by-step explanation:

Answer:

A: 1.5

B: A = n/1.5

C: This means every bowl you make, you would need 1.5 pounds of clay.

Step-by-step explanation:

A: The constant of proportionality is otherwise known as the slope. The formula for the slope is [tex]y_{2}[/tex]-[tex]y_{1}[/tex] / [tex]x_{2}[/tex]-[tex]x_{1}[/tex] (rise over run.) Lets plug the values in.

4.5-0 = 4.5

3-0 = 3

4.5/3 =1.5

B:

A = n/1.5

C:

The point (1,1.5) is representing the x value, the number of bowls, and the y value, the amount of clay in pounds.

This means every bowl you make, you would need 1.5 pounds of clay.

The equation for the Volume of a Sphere is:

V = [tex]\frac{4}{3}[/tex]πr²

You have been given the radius of 4.5 cm, so all you have to do is plug this information into the equation and solve!

V = [tex]\frac{4}{3}[/tex]π(4.5)²

       ↓

V = [tex]\frac{4}{3}[/tex]π × 20.25 or  V= [tex]\frac{4}{3}[/tex] × 20.25π

       ↓

V= 27π (plug this into your calculator to get your numerical value)

V≈ 84.82

X = 55°

Step-by-step explanation:

You can tell if a pair of angles, in this case, is 90° if you see the red box in the corner of the angle.

The pair of angles in the picture are complementary angles, which add up to 90°. Therefore, subtract 35 from 90 to find the value of X which is 55°.
