Answer: 38.31 inches

Step-by-step explanation:

We can think on the round lamp as a circle, then the inches of beads that she will need to go around the lamp is equal to the perimeter of the lamp.

The perimeter of a circle of diameter D, is:

Perimeter = pi*D

where pi = 3.14

In this case, we know that the diameter is 12.2 inches.

Replacing that in the above equation we get that the diameter of the lamp is:

Perimeter = 3.14*12.2 in = 38.31 in

Then Michelle needs 38.31 inches of the beads to go around the lamp.

Answer:

70.4metres

Step-by-step explanation:

Wheel Diameter = 0.7m

Wheel Radius; 0.7m / 2 = 0.35m

For one rotation of the wheel, the distance travelled = circumference of the wheel.

Circumference = 2 x pi x radius

= 2 × π × r

= 2 × π × 0.35

= 2.1991148575 m

Elaine tries to ride the unicycle and manages to go in a straight line for 32 full revolutions

Distance travelled with 32 full revolutions of the wheel = 32 x 2.1991148575 m =

Distance in meters = 70.37167544m

Approximately = 70.4m

Therefore, Elaine managed to cycle 70.4metres

True

Even though it landed on heads 8/10 times, ther's still a 50% chance that it will land on tails. It doesn't change the percentage of it landing on either side. So in that case, it is true.

Hope this helps!

The statement, A coin is flipped 10 times and lands on heads 8 times. The theoretical probability that the next coin flip will be heads is 50% is True.

The probability of an occurrence is a figure that represents how likely it is that the event will take place. In terms of percentage notation, it is expressed as a number between 0 and 1, or between 0% and 100%.

here, we have,

we know that,

The higher the likelihood, the more likely it is that the event will take place. A definite occurrence has a chance of 1 while an impossible event has a probability of 0.

we have,

When a coin is flipped the probability of getting a heads and a tail is 50%.

Hence, without the consideration of the flips and the result the theoretical probability that the next coin flip will be heads is 50%.

The statement, A coin is flipped 10 times and lands on heads 8 times. The theoretical probability that the next coin flip will be heads is 50% is True.

Answer:

95.04

Step-by-step explanation:

72.00 x 32%=23.04

23.04+72=95.04

Answer:

A and E.

Step-by-step explanation:

Using the math from 7th grade, 6 rooted is 36/9=4+10 is 14. Everything else you must multiply everything in parenthesis, by the outside number, then you add them. E is right because -15+35=20-6=14. Yw.

Answer:

y> -1

Step-by-step explanation:

2(5y-7) > -24

Then use the Distributive Property which then eqauls to this: 10y - 14 > -24

add 14 to both sides: 10y > -10

divide by 10: y> -1

Answer:

no

Step-by-step explanation:

Answer:

This system has no solutions

Step-by-step explanation:

y=2x-9,

y=-2x+15

by substitution:

2x - 9 = 2x + 15

2x - 2x = 15 + 9

0 ≠ 24

This system has no solutions

Given:

The area model.

To find:

The area as a sum and area as a product.

Solution:

The four terms of the area model are [tex]2x^2,10x, 3x, 15[/tex].

The area as a sum is the sum of all the terms of given area model.

Area as a sum = [tex]2x^2+10x+3x+15[/tex]

                        = [tex]2x^2+13x+15[/tex]

The area as a product is the factor form of sum of all the terms of given area model.

Area as a product = [tex]2x^2+10x+3x+15[/tex]

                        = [tex]2x(x+5)+3(x+5)[/tex]

                        = [tex](x+5)(2x+3)[/tex]

Therefore, the area as a sum is [tex]2x^2+13x+15[/tex] and the area as a product is [tex](x+5)(2x+3)[/tex].

Answer:

1 hour and 45 minutes

and 1 hour

Step-by-step explanation:

x= run

y= walk

5x+2.5y = distance

5x+2.5(1.5)=12.5

solve for x

5x=8.75

x=1.75

1.75 in hours is 1 hour and (60*.75)=45

1 hour and 45 minutes

" If the marathon race participant ran for 2 hours, how many hours did the participant walk?"

We use the same equation

5x+2.5y=distance

we'll assume that they till walked 12.5 miles

which means that

5(2)+2.5y=12.5

solve for y

2.5=2.5y

y=1

1 hour

Answer:

z = 15

Step-by-step explanation:

(I quit brainly because, they deleted 1000+ answers from my account....) however if I want to see answers than I think I have to answer some questions so I'll answer this one.

First we know that y would be 180.

Therefore CD=90

y-cd=90

90=5z+z

90=6z

90=6(15)

90=90

or

90=5z+z

90=6z

/6    /6

15 = z

z = 15

Diameters of potatoes:

Median is:

After one potato used the median becomes 5 cm.

Out of 6 potatoes left, the two in the middle should give 5 cm in average

This is 4 cm and 6 cm.

Renee must have used one of the 4 potatoes on the left: 2 cm, 3 cm or 4 cm

Answer:

Number is 4

Step-by-step explanation:

.03n = 1

n = 1/.03

.12 x (1/.03) = 4

It's alright, you're not stupif. It's just a little bit complicated if it's either your first time doing it or has been a while since you did it last.

r: 16 km. d: 32 km.

The Formula is: C = 2πr. Because it says below the rest of the data that we use 3 for pi, and since we have r, which is 16, the equation becomes C = 2(3)(16).

The answer becomes 96 Kilometers.

Answer:

85.2$

Step-by-step explanation:

Answer:

Step-by-step explanation:

Question #1

- Since it is an isosceles triangle, this means that the base angles have the same value.

- The angle sum is 180°

Solve

2x+35+35=180

2x+70=180

2x=110

x=55

Question #2

- Since it is given there is a right angle, this means the angle is 90°

- The angle sum is 180°

Solve

5x+5x+90=180

10x+90=180

10x=90

x=9

It asked to find m∠A, which is 5x. So 5x=5(9)=45°

Hope this helps!! :)

Answer:

0.088

22x4 is 88 and add the 2 zeros

Step-by-step explanation:

Answer:

0.088.

Step-by-step explanation:

0.22 * 0.4

Now 22 * 4 = 88 and

there are 3 numbers after the decimal points in 0.22 and 0.4 so there has to be 3 numbers after the decimal point in the answer, so it's:

0.088.

Answer: lol why so expensive.

Answer:

42

Step-by-step explanation:

Test worth = 50

To obtain a grade percent = 84%

Score to obtain = x

Using the expression :

84% of test worth = x

84/100 * 50 = x

0.84 * 50 = x

42 = x

Score to obtain = 42

Answer:

H:Median

Step-by-step explanation:

We know that Median means the middle, and we know that lines AB or in the middle of the page.

Answer:

b ≈ 25.7, C ≈ 24.2, A ≈ 119.8

Step-by-step explanation:

b² = a² + c² - 2ac·cos(B)

b² = 38² + 18² -2·38·18·cos(36°) ≈ 661.26475

b ≈ 25.715

sin(C)/c = sin(B)/b

C = arcsin(c/b·sin(B)) ≈ 24.29515°

∠A can be found as 180° - ∠B - ∠C

A = arcsin(a/b·sin(B)) ≈ 119.70485°
