Answer:

∠ V = 130°

Step-by-step explanation:

In a parallelogram opposite angles are congruent and consecutive angles are supplementary.

∠ S and ∠ V are not opposite angles, they are consecutive, then

∠ S + ∠ V = 180°

50° + ∠ V = 180° ( subtract 50° from both sides )

∠ V = 130°

Hey There! Allow me to explain how to solve this (I will not say the answer bc I also don't know but here is how you can find it). As you see the shape is a Cyclinder & the formula for it is V=Bh or V=πr2h. You might wanna start with solving the problems (8x - 4) & (11x + 12) Use the order of PEMDAS (Parrenthesis, Exponets, Multiplication, Division, Addition, Subtraction.) to solve is so if solving (8x - 4) And if x = 8 than first begin with mutiliplying 8 x 8 (Because it says 8x and x = 8 which means we are multiplying) than subtract that with 4 (Which will be 64 - 4). Than for (11x + 12) you will wanna do 11 x 8 which is 88 added by 12 which that will be 100. Than use the formula (V=Bh or V=πr2h) And you should have you're answer! I hoped this help and sorry for not finding the answer but atleast I explained to you on how to solve it! <3

Write the equation in standard form of the line that
passes through the point (4, -2) and has a slope of -1/2.

Answers

Answer:

x+2y=0

Step-by-step explanation:

y-y1=m(x-x1)

y-(-2)=-1/2(x-4)

y+2=-1/2x+4/2

y+2=-1/2x+2

y-(-1/2x)=2-2

y+1/2x=0

1/2x+y=0

2(1/2x+y)=2(0)

x+2y=0

A shipping container will be used to transport several 100-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 27500 kilograms. Other shipments weighing 6800 kilograms have already been loaded into the container. Write and solve an inequality which can be used to determine xxx, the number of 100-kilogram crates that can be loaded into the shipping container.

Answers

Answer:

x ≤ 207 crates

Step-by-step explanation:

Greatest weight of the container = 27,500 kilograms

Weight of other shipment = 6,800 kilograms

Weight of a crate = 100 kilograms

Number of 100-kilogram crates that can be loaded into the shipping container = x

The inequality is

27,500 ≤ 6800 + 100x

27,500 - 6800 ≤ 100x

20,700 ≤ 100x

x ≤ 20,700 / 100

x ≤ 207 crates

Each person gets 45,000

Answer:

$90,000;$135,000;$225,000

Step-by-step explanation:

In this question we have to find the share of each person

First we have to find the sum of all the ratios,

[tex]2 + 3 + 5 \\ = 10[/tex]

Then we have to represent their share as a fraction and then multiply it by the total value,

The share of first person:-

[tex] \frac{2}{10} \times 450000 \\ = 2 \times 45000 \\ = 90000[/tex]

So the first person share is $90,000

The share of second person:-

[tex] \frac{3}{10} \times 450000 \\ = 3 \times 45000 \\ = 135000[/tex]

So the second person share is $135,000

The share of third person:-

[tex] = 450000 - (135000 + 90000) \\ = 450000 - 225000 \\ = 225000[/tex]

So the third person share is $225,000

Answers

a. y=-2.5x+50

b. slope=-2.5. y-intercept=50

Answer:

slope is -2.5

y-intercept is (0,50)

slope y-intercept is y= -2.5x + 50

Step-by-step explanation:

to find the slope you use rise/run the rise is 5 and the run is -2 which is 5/-2 or -2.5

the y-intercept is where the line hits a perfect point on the y-axis which would be at 50 in your case

y=mx+b

m= slope and b= y-intercept

why is m the slope? because the slope is the unknown variable

Answers

Answer:

b. y = x + 4

Step-by-step explanation:

So we know at x = 0, or the middle black line, the red line is touching 4 so y = 4. 4 is the y intercept so the equation should say "+ 4"

Then, we can see that when the red line increases up by 1 value, it also increases 1 value to the right so that would be 1/1 which equals to 1x.

Therefore the correct answer is y = x + 4

Answer:

x=40

Step-by-step explanation:

x + 320 = 360

-320 -320

x = 40

Answer:

x=40

Step-by-step explanation:

So, since the figure has 4 sides, we know that the sum of the interior angles is 360. To check: (n-2)*180=(4-2)*180=28180=360.

That means x equals 360 minus the sum of the other three angles.

100+120+100=320

360-320=40

x=40 degrees

The people needed medicine, but there were no roads, and the harsh weather made it impossible for a plane to reach them. The only way to get medicine to Nome was by dogsled. Twenty teams of dogs, each with a handler, or musher, braved dangerous conditions to bring the medicine from Nenana, Alaska, along the Iditarod Trail to Nome.The first team to set out was led by a dog named Togo. Togo was a small, black and white husky who had spent most of his life pulling sleds. When he was a puppy, his owner, Leonhard Seppala, never thought he would be a good sled dog. Togo was smaller than most dogs on the team. He was ill when he was very young, and at six months old, he was given away to be a house pet. Togo did not last long as a pet. He escaped several times to return to the sled dog kennels. He ran after the team every day on their training runs, and eventually, he was given a chance to run in harness. He had found his purpose.Togo was a natural leader, and he was the dog Leonhard Seppala trusted the most. During the run from Nenana, he led his team through life-threatening situations. One night, when the darkness and snow made it impossible for Seppala to see where they were going, and they were in grave danger from the below-zero temperatures, Togo courageously led the team across a frozen lake, avoiding the broken areas of ice. He navigated to the rest stop, saving his team from freezing in the blizzard. Togo's team brought the medicine almost 200 miles, crossing a mountain with an elevation of more than 5,000 feet and swimming through ice floes on the other side. They reached their drop-off point and passed the medicine to the next team. After the drop-off, Togo rested for a while before taking off with some of the other dogs on his team to chase reindeer. It was like a small vacation after his hard work.The last team to carry the medicine was led by another dog, Balto. Balto's team made it to Nome in the nick of time. The medicine saved the town, and Balto was hailed as a hero dog. A statue of him was built and displayed for all to admire. Even though Togo faced greater danger and ran farther than Balto, most people honored only Balto. Togo was truly an unsung hero with the heart of a lion. Today, the dogsled journey to save Nome is remembered as the Great Race of Mercy, and every year, a dogsled race along the Iditarod Trail is run to remember the courageous and determined dogs who saved the people of Nome.Which information would disprove the author's point that Togo was an unsung hero? The winner's plaque for the Iditarod has a picture of Togo and the words Miracle" on it. The statue of Balto is large and impressive and appears with a powerful poem of thanksgiving. The most popular dog names in Alaska are Balto, Leonhard, Mercy, Nome, and Nenana. Every year at the beginning of the Iditarod race, the crowd chants Balto! Balto!" loudly.
