Step by Step Solution

System of Linear Equations entered :

 [1]           x+4y=0

 [2]           16y-4x

Equations Simplified or Rearranged :

  [1]    x + 4y = 0

B.) 1020 mi ^2

Since the next largest city is Anchorage, Alaska you would just subtract Juneau's land area from Anchorage's land area.

B

Step-by-step explanation:

Fristly we will apply BODMAS rule .i.e Brackets of Divison Multiplication Addition and then Substraction.

So first we will solve (5+3)^2 which is equal to 64.

Then we will solve 3^3 which is equal to 27.

now 27 times 2 is 54.

At last 64 - 54 comes out to be 10.

m<11 = 100 m <12 = 80

Step-by-step explanation:

m <5 = 100°

m <5 = m <11 ( alternate exterior angles)

•°• m <11 = 100

<11 & <12 are supplementary

•°•m <11 + m <12 = 180

= m <100+m <12 = 180

= m <12 = 180- 100

Answer:

275/9

Step-by-step explanation:

9/10x + 4/5 = 28.3

leave out the decimal sign in 28.3 and then turn it into a fraction.

9/10x + 4/5 = 283/10

Multiply them by 10

9/10x • 10 = 9x

4/5 • 10 = 8

283/10 • 10 = 283

9x + 8 = 283

Separate the x from the non x

9x = 283 - 8

= 275

9x = 275

275/9 = x

The solution to the equation 9/10 x+4/5=28.3 is x = 275/9, Option B is correct.

Two or more expressions with an Equal sign is called as Equation.

The given equation is 9/10 x+4/5=28.3

Nine by ten times of x plus four by five equal to twenty eight point three

x is the variable in the equation

We have to solve for x

Subtract 4/5 from both sides

9/10x = 28.3 - 4/5

9/10x= 28.3 -0.8

9/10x=27.5

9x=27.5×10

9x=275

Divide both sides by 9

x=275/9

Hence, the solution to the equation 9/10 x+4/5=28.3 is x = 275/9, Option B is correct.

The perimeter of the floor in the scale is 46 inches

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference.

The length of the actual floor is 22 feet and the length in scale is 11 cm. This means the scale factor is 2 feet is 1 inches

Therefore the the width of the floor in scale = 24/2 = 12 feet

Perimeter = 2( l+w)

therefore the perimeter of the floor in the new scale = 2(11+12)

= 2× 23

= 46 inches

therefore the floor in the scale drawing is 46 inches

Answer:

m<1=31 degrees and m<2=106 degrees

Step-by-step explanation:

To find m<1 you have to do m<2 first. Use the 74 degrees from m<4 and subtract that from 180. 180-74=106. With that information you can find m<1. Take 106 from m<2 and 43 from m<3 and subtract that from 180. 180-106-43=31.

Answer:

m<1=31 & m<2=106

Answer: [tex]\frac{11\pi}{96}[/tex]

Step-by-step explanation:

See attached images.

see image

basically, you have to find the side lengths using the distance between points formula

[tex]\sqrt{|y_2-y_1|^2+|x_2-x_1|^2[/tex]

then you need the law of sines to find one of the angles

solving for the angle that formula is;
[tex]Y (gamma ) = cos^-1(\frac{a^2+b^ 2-c^2}{2ab})[/tex]

Y, or gamma, is the angle opposite C.

then i plugged it into the formula area = 1/2 a * b * sin (C)

Step-by-step explanation:

Answer:

There are 56 oranges in the basket, since the ratio of apples to oranges is 9:7. To calculate this, you can use the proportion method. First, set up a proportion using the ratio of apples to oranges (9:7):

9/7 = x/128

Then, solve for x.

x = (9/7) * 128

x = 112

Answer:

72 and 56

Step-by-step explanation:

Ratio of apples in the basket = 9x

Ratio of oranges in the basket = 7x

Total fruits in the basket = 128

So, Apples + Oranges = Total fruit

9x + 7x = 128

16x = 128

x = 128 ÷ 16

x = 8

∴ So, number of apples = 9x --> 9*8 = 72 apples

number of oranges = 7x --> 7*8 = 56 oranges

Answer:

Step-by-step explanation:

From the diagram, and knowing that the measure of a straight line, we know that the angle right above the 45 degree angle, is 180-45, because a straight line has a measure of 180 degrees. That gives us 135 degrees. We know that a triangle has a total measure of 180 degrees, like a straight line. Now, we can combine the 2 angles we do know, and subtract that from 180. Ok, lets do it. 135+22=157. Now we subtract to find the final angle in the triangle. 180-157=23. Therefore, the angles in our triangle are 135, 22, and 23. We can check our work by adding all these angles together, and if they add to 180, we know it is correct. And they do. Now, using the same rule as before, we can subtract the final angle, next to the x, by 180, to get x. 180-23=157.

Therefore, we know x = 157.

Answer:

assuming the value x = 1/3 and y = 1/4

so if you use both value in an addition equation, you'll get this equation :

[tex] \frac{1}{3} + \frac{1}{4} [/tex]

which then you can simplify by making both fraction have the same value :

[tex] \frac{1}{3} \times \frac{4}{4} + \frac{1}{4} \times \frac{3}{3} [/tex]

[tex] \frac{4}{12} + \frac{3}{12} [/tex]

therefore you get the answer :

[tex] \frac{7}{12} [/tex]

So this equation shows that the denominator 3 and 4 are related to 12.

The denominators 3 and 4 are related to 12 in a multiplication equation, you can express it as 1/3 * 1/4 = 1/12

The denominators 3 and 4 are related to 12 in a multiplication equation, you can express it as:

1/3 * 1/4 = 1/12

In this equation, the product of 3 and 4 (which is 12) represents how the denominators 3 and 4 combine to give the common denominator of 12. In fractions, when you need to find a common denominator to add or subtract fractions with different denominators, you can use this multiplication relationship. For example, if you have fractions with denominators 3 and 4, you can convert them to fractions with a common denominator of 12 by multiplying both the numerator and the denominator of each fraction by the appropriate factor to get:

1/3 = (1 * 4) / (3 * 4) = 4/12

1/4 = (1 * 3) / (4 * 3) = 3/12

Now both fractions have a common denominator of 12, and you can easily add or subtract them.
