Answer 1
if ya meant like [tex]\frac{1}{2}x=20[/tex]
multiply both sides by 2/1 to get x=40

if ya meant like [tex]\frac{1}{2x}=20[/tex]
multiply both sides by x and divide both sides by 20 to get [tex]x=\frac{1}{40}[/tex]

If trap is an isosceles trapezoid, what is the value of x

Answers

Answer:

Option E ⇒  x = 19

Step-by-step explanation:

See the attached figure.

TRAP is an isosceles trapezoid

The shown angles are supplementary angles

So, the sum of (5x+9) and (4x) is 180

So, 5x+9 + 4x = 180

solve for x

9x + 9 = 180

9x = 180-9 = 171

x = 171/9 = 19

The answer is option E

how long would it take for an egg dropped from a helicopter to fall 256 feet to the ground? d=16t^2

Answers

Well the position function is:

h(t)=-16t^2+256

It will hit the ground when h(t)=0

-16t^2+256=0  factor out -16

-16(t^2-16)=0  factor difference of squares...

-16(t+4)(t-4)=0, since t>0

If the area of a rectangle is 24a2b and the length is 8ab2, what would be the width of the rectangle, given that width is found by dividing area by length? Simplify the answer.

the quantity of 3 times a all over b
b over the quantity 3 times a
3 over the quantity a times b
3ab

Answers

Answer:

Option the quantity of [tex]3[/tex] times a all over b

Step-by-step explanation:

we know that

The area of rectangle is equal to

[tex]A=LW[/tex]

where

L is the length side of rectangle

W is the width side of rectangle

In this problem we have

[tex]A=24a^{2}b\ units^{2}[/tex]

[tex]L=8ab^{2}\ units[/tex]

Remember that

[tex]W=\frac{A}{L}[/tex]

substitute

[tex]W=\frac{24a^{2}b}{8ab^{2}}=\frac{3a}{b}\ units[/tex]

[tex]\sqrt{10000x^{64}}=100x^{32}[/tex]

Step-by-step explanation:

Given : Expression [tex]\sqrt{10000x^{64}}[/tex]

We have to write a simplified form of the given expression [tex]\sqrt{10000x^{64}}[/tex]

Consider the given expression [tex]\sqrt{10000x^{64}}[/tex]

In a rain forest, it typically rains 290 days out of the year. If it rains today, what is the probability that it will rain tomorrow?

a. 72%
b. 81%
c. 79%
d. 61%

Answers

Hey there!

Since we weren't given any probabilities based on the chance of rain after it rained the day before, we can assume the probability will stay the same. We can disregard "If it rains today...". 

If it rains 290 days out of the year (365 days), there will be a 290/365 chance of rain of a particular day. You can divide 290 by 365 to get a 79% chance.

6 over 15 multiplied by 2 over 14 is equal to 12 over 210

6 over 15 plus 2 over 15 is equal to 8 over 15

Answers

2+6+7 = 15 total cakes

6 pineapple so probability is 6/15

 then there would be 14 cakes

2 strawberry for a probability of 2/14

6/15 x 2/14 = 12/210

 the first answer is the right one

Answer:

[tex]\frac{12}{210}[/tex]

Step-by-step explanation:

Strawberry cakes = 2

Pineapple cakes = 6

Chocolate cakes = 7

Total cakes = 15

Now we are given that  Vincent selects a cake randomly without looking, and he will give a pineapple cake to the first child

So, probability of getting a pine apple cake in first draw = [tex]\frac{\text{No. of pineapple cakes}}{\text{Total no. of cakes}}[/tex]

                                                                                             = [tex]\frac{6}{15}[/tex]

Now total no. of remaining cakes = 15-1 =14

Now we are given that  Vincent selects a cake randomly without looking, and he will give a strawberry cake to the second child

So, So, probability of getting a strawberry cake in second draw= [tex]\frac{2}{14}[/tex]

So,  the probability that he will give a pineapple cake to the first child and then a strawberry cake to the second child =  [tex]\frac{6}{15} \times\frac{2}{14} [/tex]

                                                                           =  [tex]\frac{12}{210}[/tex]

Hence Option A is true.

The probability that he will give a pineapple cake to the first child and then a strawberry cake to the second child is [tex]\frac{12}{210}[/tex]

Answers

We have to convert feet to inches:
1 foot = 12 inches
1.7 feet = 1.7 * 12 = 20.4 in
The formula for the volume is:
V = l * w * h
and:  l = 19 in, w = 20.4 in,  h = 6 in.
V =  19 in * 20.4 in * 6 in = 2,325.6 in³

which of the following best describes a regular polygon when the sum of its interior angles is 1080 degrees A.) octagon B.) heptagon C.) hexagon D.) nonagon

Answers

a) octagon

1080= (n-2)180
1080/180=6

6=(n-2)
n=8
(This is the formula for finding the sum of interior angles in polygons. n represents the number of sides in the polygon)

Answer:

Option A is correct.

Step-by-step explanation:

Given: Sum of all the interior angles of a regular polygon = 1080°

To find: number of sides or name of polygon.

We know that Sum of all interior angle of a regular polygon is given by following formula,

Sum of all angles = ( n - 2 ) × 180° ,    where n = no of sides.

⇒ 1080° = ( n - 2 ) × 180°

n - 2 = 6

n = 6 + 2

n = 8

Name of regular polygon is Regular Octagon.

Therefore, Option A is correct.

Line A: 2x + 2y = 8 Line B: x + y = 4 Which statement is true about the solution to the set of equations? It is (8, 4). It is (4, 8). There is no solution. There are infinitely many solutions.

Answers

We want to check how many intersections line A and B have, that is, we want to check how many common solutions do these equations have:

i) 2x + 2y = 8

ii) x + y = 4

use equation ii) to write y in terms of x as : y=4-x, 

substitute y =4-x in equation i):

2x + 2y = 8
2x + 2(4-x) = 8
2x+8-2x=8
8=8

this is always true, which means the equations have infinitely many common solutions.


Answer: There are infinitely many solutions.

Find the outlier of the set of data: 24, 37, 33, 31, 28, 25, 33, 12

Answers

Outlier - A value that "lies outside" than most of the other values.

The outlier is therefore 12, because it is not in the general range of values, which is on average around 29.

Answer:

The outlier of the set is 12.

Step-by-step explanation:

Consider the provided set of data:

4, 37, 33, 31, 28, 25, 33, 12

The outlier is a kind of data which is abnormal distance from the other points.

Or the data that lies outside the other value in the provided set.

Now consider the data.

12 is lies outside the other values because the distance is abnormal.

The number 12 is not close to any of the other numbers.

Hence, the outlier of the set is 12.

explain the place value relationship when the same two digits are next to each other in a multidigit number

Answers

For example, the value of digit 3 in 5833

5833 = 5000 + 800 + 30 + 3

The digits 3 in 5833 has value of 30 and 3
One value is ten times the other

Another example, the value of digit 6 in 586645

586645 = 500000 + 80000 + 6000 + 600 + 40 + 5

The digits 6 in 586645 is 6000 and 600
One digit is 10 times the other

We can make a conclusion that the place value relationship when the same two digits are next to each other is one digit will always be 10 times the other digit.

You need to pump water out of a flooded basement, using two 50-gallon-per-minute (gpm) pumps. The basement has the dimensions shown and is flooded to a depth of 16 inches. How long will it take to pump the water out of the basement?

Answers

The two pumps working together would pump out water at a rate of 100 gallons per minute. To determine the time it takes to completely pump out the water from the basement, we need to determine the volume of the water in the basement. The dimensions of the basement is 40 feet by 50 feet (given elsewhere) while the depth of the water is said to be  16 inches. From these dimensions, we can calculate for the volume as follows:

V = length x width x depth
length = 50 feet
width = 40 feet
depth = 16 inches ( 1 foot / 12 inches ) = 1.33 feet

V = 50 x 40 x 1.33 = 2666.67 ft^3 = 19948.05 gal

Time = V / rate
Time = 19948.05 gal / 100 gal / min
Time = 199.48 min
