Answer:

x=19

Step-by-step explanation:

Answer:

x = -10 ; y = -40

Step-by-step explanation:

Note:

y = 4x.

Plug in 4x for y in the first equation:

x + y = -50

x + (4x) = -50

Solve for x. First, simplify, then isolate the variable, x.

x + 4x = -50

5x = -50

Divide 5 from both sides of the equation.

(5x)/5 = (-50)/5

x  = -50/5

x = -10

Plug in -10 for x in one of the equations:

y = 4x

y = 4(-10)

y = -40

x = -10 ; y = -40 is your answer.

Answer:

  d  5,15,19​

Step-by-step explanation:

The sum of the shortest two sides must be longer than the longest side. That is only the case for selection D.

__

If the sum is equal to the longest side, the segment ends will meet, but the "triangle" will look like a line segment. Many authors do not allow such a thing to be called a triangle. Hence, 'b' is not an answer to this question.

(Some authors do allow such a triangle, in which case, there would be two answers here: B and D.)

Answer:

500

Step-by-step explanation:

20% of x = 100

Write 20% as a decimal - - > 0.2(x) = 100

Isolate and solve for x - - > x = 100/0.2

Therefore, x = 500

Answer:

500

Step-by-step explanation:

Let the no. be x

20% of x = [tex]\frac{20}{100} x[/tex]

And ,

[tex]\frac{20}{100} x = 100\\=> 20x = 10000\\ => x = \frac{10000}{20} = 500[/tex]

Answer:

y= -12x+63/4

Step-by-step explanation:

16x + 4/3 y = 21

4/3 y =21-16x

4y=3(21-16x)

4y=63-48x

y=63/4-48/4 x

y=-12x+63/4

Answer:

x = 7/3

Step-by-step explanation:

First, combine like terms:

7x + 2x - 2 + 14 = 33

(7x + 2x) + (14 - 2) = 33

9x + 12 = 33

Isolate the variable, note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 12 from both sides:

9x  + 12 (-12) =  33 (-12)

9x = 33 - 12

9x = 21

Next, divide 9 from both sides:

(9x)/9 = (21)/9

Simplify. Divide common factors:

x = (21/9)/(3/3) = 7/3

x = 7/3

-3.2(-5.6)(4)

= -3.2 - 5.6 x 4

= -3.2 - 22.4

= -25.6

Answer:

-10

Step-by-step explanation:

well you know that

[tex](-)(-)=(+)[/tex]

so we have

[tex]-21-(-11)\\\\=-21+11\\\\=-10[/tex]

Answer:

9y+3

Step-by-step explanation:

you add all the common numbers and you end up with:

9y^6+3+y^-5

then you put the y^-5 under the other numbers and make it positive so it becomes:

9y^6+3/y^5, then you subtract the exponents of y: 6-5, so that cancels out the y on the bottom making it:

9y+3

Answer:

1,2,5

Step-by-step explanation:

The first pattern has a difference of 5 while the second is 10 and become by multiplying 2 in pattern 1 so options (A),(B), and (E) will be correct.

A pattern is a specific arrangement of numbers or any term which will follow a specific code or hint.

The hint which is present in a given pattern hides in the pattern only.

For example 2,4,6,8 in this, the difference between any two-term is only 2 and this will be its specific pattern.

Another example is 2,4,16,256 in this pattern each term is the square of the previous term and this will become its specific pattern.

Given the two patterns.

In the first pattern, each term become by adding 5 so option (A) is correct.

In the second pattern, each term become by adding 10 so option (B) is correct.

The term in the second pattern becomes by multiplying 2 in pattern 1

For example 5× 2 = 10 and 10 × 2 = 20 so option (E) will be correct.

Hence "The first pattern has a difference of 5 while the second is 10 and become by multiplying 2 in pattern 1".

#SPJ2

Answer:

width=3

Step-by-step explanation:

area=length X width

length=4 X width

=>area=4 X width X width

=>area=(2 X width)^2

=>36=(2 X width)^2

=>6=2 X width

=>width=3

the area of a rectangle is length times width

A = L times W

A = 26. so 36 = L times W

The length is 4 times the width

L = 4W

Thus, we can switch L to 4W in the area equation

36 = 4W ×W = 4W²

36 ÷ 4

=√9

=3cm

Answer:

Step-by-step explanation:

The answer is A

The answer is 1.158505

Answer:

My answer to the question is 24.

Answer:

A= 29

B=34

C=117

Step-by-step explanation:

A triangle has three sides and a triangle always adds up to be 180

A + B + C = 180

B = A + 5

C = 4A + 1

Plug in.

A + A + 5 + 4A + 1 = 180

6A + 6 = 180

6A = 174

A = 29

Now since you found A, find the other two by plugging A in!

C = 4(29) + 1

C = 117

Plug in the B equation

B = 29 + 5

B=34

Check your answers

29 + 117 + 34 = 180

Answer:

88°

Step-by-step explanation:

Complementary angles have a sum of 90°, just do 90 - 2 and there's your answer.

Given :

A point ( 1 ,4 ,5 ).

To Find :

The projection of the point on the xy-plane .

Solution :

Now , to find projection of a point in a plane in a plane we need to replace the coordinate of that remaining axis which is not in the plane .

Here , the plane given is xy-plane . So , remaining axis is z .

So , we replace coordinate of z =0 .

Therefore ,  the projection of the point ( 1 ,4 ,5 ) on the xy-plane is ( 1 ,4 ,0 ) .

Hence , this is the required solution .

Answer:

a) perpendicular b) parallel c) perpendicular  d) neither

Step-by-step explanation:

Perpendicular means that the lines will intersect/cross and create a 90 degree angle

Parallel lines will never intersect/cross because they are going the same way.

Answer:

96

Step-by-step explanation:

Answer:

96

Step-by-step explanation:

95.85≅96, because 8>5.

Step-by-step explanation:

From the given gummi bear, the chance that Adam is selected for any draw is 1/3 as well as the chance he is not selected at any draw is 2/3.

a). The probability of Adam getting exactly three gummi bears = P(Adam gets selected at 3 draws and not selected at the remaining 9 draws)

= [tex]$ (\frac{1}{3})^3 (\frac{2}{3})^9 = \frac{2^9}{3^{12}} $[/tex]

Now, the 3 draws where Adam gets selected can be any 3 out of 12 draws in [tex]$ {\overset{12}C}_3 $[/tex] = 220

Thus, probability of Adam getting three gummi bears = [tex]$ 220 \times \frac{2^9}{3^{12}} $[/tex]

                                                                                                = 0.21186

b). Probability that Adam will get the three gummi bears given each person will received at the most 1 gummi bear

= P(of the remaining 9 draws after assigning one gummi bear to each one, Adam gets selected at 2 draws and not selected at 7 draws) = [tex]$ {\overset{9}C}_2 (\frac{1}{3})^2 (\frac{2}{3})^7 $[/tex]

                                                                                               = 0.23411

c). Let X = Number of the gummi bears which Adam will get. Then, X = number of draws out of 12 draws Adam gets selected and X ~ B(12, 1/3). So,  Adam will get gummi bears= mean of B(12, 1/3) = 12 x (1/3) = 4

d). Let Y = Number of the gummi bears that Adam will get, given each person will received at the most 1 gummi bear Then, Y = number of draws Adam gets selected in the remaining 9 draws and Y ~ B(9, 1/3). So, the expected number of bears that Adam gets given each person received at least 1 gummi bear

= 1 + mean of B(9, 1/3) = 4

e). When every one gets atleast one gummi bear, the new sample size will be 9 and so we can say that there is a reduction in variance.
