Answer 1

Answer:

9 feet

Step-by-step explanation:

The given is 30-60-90 special triangle with the side lengths as follows

x-x√(3- and 2x

The side length that sees 90 degrees (hypotenuse) is 18 which means x = 9

then the side length that sees 30 degrees is 9 as well

Answer:

c=10

Step-by-step explanation:

pythagreom theroem

c (hypotenuse) = [tex]\sqrt{a^{2} +b^{2} }[/tex]

plug in values for a and b

c=[tex]\sqrt{6^{2} +8^{2} }[/tex]

c=[tex]\sqrt{36+64\\}[/tex]

c=[tex]\sqrt{100\\}[/tex]

c=10

Answer:

length of the hypotenuse = √100 = 10 ft

Step-by-step explanation:

This is a right triangle with leg lengths 6 and 8 ft.  We apply the Pythagorean Theorem a^2 + b^2 = c^2, as follows:

(6 ft)^2 + (8 ft)^2  = c^2

Then c^2 = 100, and c = length of the hypotenuse = √100 = 10 ft

find the surface area of each figure. round to the hundredths place

Answers

Given:

In the given cone,

Radius of the cone = 7.2 m

Slant height of the cone = 17 m

To find:

The surface area of the cone.

Solution:

The surface area of a cone is:

[tex]A=\pi rl+\pi r^2[/tex]

Where, r is the radius of the cone and l is the slant height of the cone.

Putting [tex]\pi=3.14,\ r=7.2,\ l=17[/tex] in the above formula, we get

[tex]A=(3.14)(7.2)(17)+(3.14)(7.2)^2[/tex]

[tex]A=384.336+162.7776[/tex]

[tex]A=547.1136[/tex]

[tex]A\approx 547.11[/tex]

Therefore, the surface area of the given cone is 547.11 square m.

Step-by-step explanation:

. Is (4,-3) a solution to the following system of equations?
X - y = 4
2x + y = 5
(Use elimination method)

Answers

Answer:

No. The correct solution is (3,-1)

Step-by-step explanation:

Since we are using elimination method, we can go ahead and see that we can cancel "-y" from the first equation and "+y" from the second equation.

Once  we do that, we go ahead add the like terms and get 3x = 9

Then, we divide by 3 on each side and get  x = 3

Now, we can take that value of x and plugin to any of the original 2 equations we started with.

Say we plugin x = 3 into the second equation.. it will turn to, 2(3) + y = 5

Then we solve for y.

2(3) + y = 5

6 + y = 5

6 - 1 = 5

y = -1

There, we found our x value and our y value, (3,-1)  :)

5) Find the value of x

Answers

Answer:

x = 28

Step-by-step explanation:

the angle shown is a right angle

right angle = 90°

•°• (x + 6) + 56 = 90

=> x + 62 = 90

=> x = 90 - 62

=> x = 28

Answer:

28

Step-by-step explanation:

5)

(x + 6)° + 56° = 90°

x + 6 + 56 = 90

x + 62 = 90

x = 90 - 62

x = 28

A jar contains 3 yellow and 7 green marbles. You randomly draw one marble from the jar then REPLACE it and randomly draw a second marble. Find the probability that you draw a yellow marble first and then a green marble.

Answers

3 yellow + 7 green = 10 total marbles.

The probability of picking a certain color is the number of that color over the total quantity.

Picking yellow would be 3 yellow / 10 total = 3/10

Picking green would be 7 green / 10 total = 7/10

To find the probability of doing both multiply the probability of each one by each other:

3/10 x 7/10 = 21/100

The answer would be 21/100

Answer: 7

Step-by-step explanation:

2x(3x-5) -3(x-3)2(2)(3(2)-5) -3(2-3)      First you substitute 2 for all the x's. The twos in  .                                      parentheses  represent multiplication.4(6-5) -3(2-3)               Second, you multiply 2 by 2, which equals 4,           .                                     and multiply 3 by 2, which equals 6. 4(1) -3(-1)                       Next, you solve the problems in the                          .                                      parentheses, which is 6 minus 5 is 1, and 2          .                                      minus 3 is -14-(-3)                              Next, you multiply 4 by 1, which is 4, and                .                                      multiply 3 by -1.4+3                                Since two negatives make a positive, the             .                                     equation changes to 4 plus 3.7                                     Finally, you add 4 plus 3 and get 7.

What is algebra?

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.

let the two pieces be x(longer) and y (shorter)

So,

x+y=31

and, 3x=4y

3x-4y=0

Solving both the equations:

x= 124/7 and y=93/7

Hence, the length of longer piece is 124/7.

Mean: The sum of all numbers divided by the amount of numbers.

Median: The number in the middle.

Mode: the number that is frequently used.

------------------------------------------------------------------------------------------------------

Mean: 1 + 4 + 8 + 3 + 4 + 5 + 2 + 2 + 2 + 5 = 36 ÷ 10 = 3.6

Median: 1, 4, 8, 3, 4, 5, 2, 2, 2, 5. since two numbers are in the middle, we need to add 3 + 4 ÷ 2 = 3.5

Mode: 1, 4, 8, 3, 4, 5, 2, 2, 2, 5. The mode is two because it is used the most.
