Answer:

  (x, y) = (5, 0)

Step-by-step explanation:

Maybe you're trying to solve the system ...

It is convenient to add the two equations to eliminate the y-variable.

  (3x +8y) +(2x -8y) = (15) +(10)

  5x = 25 . . . . . . simplify

  x = 5 . . . . . . . . divide by 5

Substituting into the first equation, we have ...

  3(5) +8y = 15

  8y = 0 . . . . . . . subtract 15

  y = 0 . . . . . . . . divide by 8

The solution to the pair of equations we think you want to solve is ...

  (x, y) = (5, 0)

Answer:

The ANOVA table and the solution are attached below

Answer:

B

Step-by-step explanation:

Since the equation is all positive, the curve should concave towards the 4th quadrant.

Answer:

Denote B(x, y), we have:

-10 + x = 2 x (-16) => x = -22

  8 + y = 2 x 6 => y = 4

=> B(-22, 4)

Answer:

20 kernels

21 Berries

Step-by-step explanation:

Belinay is making garlands of popcorn kernels and berries to feed the wildlife. The diagram shows the ratio of popcorn kernels to berries Belinay uses on the garlands

Kernels 4

Berries 3

Kernerls : Berries :: 4 : 3

in Garland  A  - Berries = 15

if berries  = 3  then  Kernel  = 4

=> if berries  = 1  then  Kernel  = 4/3

=> if berries  = 15  then  Kernel  = 15 * 4/3  = 20

Kernels in Garland A = 20

in Garland B  -  Kernel = 28

if Kernel = 4  Then Berries = 3

=> if Kernel = 1  Then Berries = 3/4

=> if Kernel = 28  Then Berries = 18 * 3/4 = 21

Beriies in Garland B = 21

Garland         Kernels             Berries

A                     20                   15

B                      28                   21

Answer:

Garland         Kernels             Berries

A                     20                   15

B                      28                   21

Answer:

A

Step-by-step explanation:

The name of the point represented by V is an orthocenter. Option A

A triangle's point of concurrency is its orthocenter. It is the location where the triangle's three altitudes come together.

A line segment drawn perpendicular from a triangle's vertex to the other side or its extension represents the triangle's altitude.

Usually, the letter "H" is used to indicate the orthocenter. It is a crucial point in triangle geometry and has a variety of characteristics and connections to other triangle points like the circumcenter and centroid.

Answer:

  about 76.2°

Step-by-step explanation:

The geometry can be modeled by a right triangle with the given dimensions being the side opposite the angle (height = 33,500 ft) and the side adjacent to the angle (8,200 ft). The fact that you know these two sides suggests the inverse of the tangent function may be useful.

  Tan = Opposite/Adjacent

  tan(angle) = (33,500/8,200)

  angle = arctan (335/82) ≈ 76.246°

The angle of elevation is about 76.2°.

Answer:

74 and 27

Step-by-step explanation:

let x and y be the numbers

x + y =101........eqn 1

x - y = 47.......eqn 2

solve simultaneously

from equation 2, make x the subject

x= 47 + y........eqn 3

put eqn 3 into eqn 1

(47+y) + y = 101

47 + 2y = 101

       2y= 101 - 47

       2y=54

         y= 54/2

         y= 27

put y=27 into eqn 3

x = 47 + 27

x = 74

Answer:

Continue the pattern 24 more times by multiplying 24 terms with 3 subtracted per term

24x3=72

subtract 72 to find the term

8-72=-64

Should be -64 but we will still continue the pattern to double check

8,5,2,-1,-4,-7,-10,-13,-16,-19,-22,-25,-28,-31,-34,-37,-40,-43,-46,-49,-52,-55,-58,-61,-64

-64 is the 25th term

Answer:

The circumference of the​ circle is [tex]C=56.55 \:m[/tex].

Eugene confused the radius with the diameter to find the circumference of the circle.

Step-by-step explanation:

The circumference of a circle is the distance around the outside of the circle.

The circumference of a circle is found using this formula:

[tex]\begin{matrix} C=\pi \cdot d\\or\\ \, C=2\pi \cdot r \end{matrix}[/tex]

From the information given the diameter of the circle is 18 m. Therefore, the circumference of the​ circle is

[tex]C=\pi \cdot d\\\\C=3.14 \cdot 18 \approx 56.55 \:m[/tex]

Eugene used the wrong formula to find the circumference of a circle.

[tex]C=2\cdot(3.14)\cdot 18=113.04 \:m[/tex]

He confused the radius with the diameter.

Answer:

V^2 - 11/8

Step-by-step explanation:

8(V^2 - x) =11

V^2 = 11/ 8 + X

X= V^2 - 11/8

Answer:

x= - [tex]\frac{11}{8}[/tex]+[tex]\sqrt{2[/tex]

Step-by-step explanation:

Distribute the 8, which becomes.... 8[tex]\sqrt{2}[/tex] - 8x = 11

Move the numbers to one side.... -8x= 11-8[tex]\sqrt{2}[/tex]

Divide by -8.......- [tex]\frac{11}{8}[/tex]+[tex]\sqrt{2[/tex]

Answer:

The claim is not true

Step-by-step explanation:

We are given that A local retailer claims that the mean waiting time is less than 8 minutes.

[tex]H_0:\mu=8[/tex]

[tex]H_a:\mu<8[/tex]

A random sample of 20 waiting times has a mean of 6.3 minutes with a standard deviation of 2.1 minutes.

[tex]\bar{x}=6.3[/tex]

s = 2.1

n = 20

Since n <30 and population standard deviation is unknown

So,we will use t test

So,[tex]t=\frac{x-\mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t=\frac{6.3-8}{\frac{2.1}{\sqrt{20}}}[/tex]

t=-3.62

α = 0.01

Degree of freedom = df=n-1=20-1=19

[tex]t_{df,\frac{\alpha}{2}}=t_{19,\frac{0.01}{2}}=2.861[/tex]

t calculated < t critical

So, we failed to reject null hypothesis

Hence the claim is not true

Answer: Equilateral, isosceles and scalene.

Step-by-step explanation:

Answer:13°

Step-by-step explanation:

a + b + x=180 sum of angles in a =180°

85° is alternate to a

Therefore a=85°

98° and b are supplementary angles

98+b=180

b=180-98

b=82°

Recall that

a + b + x=180

85+82+x=180

167 + x=180

Collect like terms

x=180-167

x=13°

Answer:

8 is the side length of the greater square.  100=x^2+(x-2)^2

Step-by-step explanation:

64+36=100

8 squared plus 6 squared equals 10 squared

8 is 2 more than 6

100=x^2 +y^2

x-y=2

100=x^2+(x-2)^2

Answer:

-66

Step-by-step explanation:

There will be $66 left after the $12 spent on lunch. 66 + -66 = 0

The number could be -66 combined with the amount left in the account to make zero.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
