The character in our video multiplied the original value for black paint by 5 to get the new value for black paint. So, she also multiplied the original value for green paint by 5 to get the new value for green paint. There are multiplicative relationships, relationships related to multiplication, in a ratio table. To get from values for green and black in one ratio to values for green and black in another ratio, we can multiply both the initial values by the same number. For example, to get from the ratio 3:2 to the ratio 6:4, we multiply both the 3 and 2 by 2. And to get from the ratio 3:2 to the ratio 15:10, we multiply both the 3 and 2 by 5.

Sometimes, there are also relationships related to addition, called additive relationships, in a ratio table. To get from one value for green to another value for green, we can add 3. To get from one value for black to another value for black, we can add 2. When using the multiplicative relationship to find equivalent ratios, we can multiply both columns by the same number. But when using the additive relationship, we cannot add the same number to both columns.

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 30 inches, and the length of the base is 10 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.

Answers

Perimeter = 78.7 inches
Step-by-step explanation:
From the given question, applying the Pythagoras theorem to one of the congruent triangles formed, we have;
= +
= +
=841 + 81
= 922
hyp =
= 30.3645
The perimeter of the triangle can be determined as;
perimeter = + +
= 30.3645 + 18 + 30.3645
= 78.729
The perimeter of the triangle = 78.7 inches

The perimeter of the triangle is 70.82 inches.

Given as :

The length of the altitude is 30 inches, and

The length of the base is 10 inches

What is right triangle?

Right triangle is defined as a triangle which one angle is a right angle or two sides are perpendicular.

Let, perpendicular = 30 and base = 5

According to Pythagoras theorem,

A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

perpendicular² + base² = hypotenuse²

Substitute the values,

30² + 5² =  hypotenuse²

900 + 25 =  hypotenuse² or

hypotenuse² = 925

hypotenuse = √925

hypotenuse = 30.41

The perimeter of the triangle can be determined as:

Perimeter of the triangle = l₁ + l₂ + l₃

Perimeter of the triangle = 30.41+ 10 + 30.41

Perimeter of the triangle = 70.82

Hence, the perimeter of the triangle is 70.82 inches.

Ed is building a model of a house with a flat roof, as shown in the diagram. There is a chimney through the roof. Ed will cover the roof with square tiles.

If the area of each tile is 1 square inch, how many tiles will he need?

Answers

Answer:

Step-by-step explanation:

3x4

You will need to find the area first so 50in x 40in =2,000in

Then find the area the chimney takes up. 4in x 3in = 12in

2,000in - 12in =1,988 tiles for the roof.

60 + 45 = 105 therefore the area is 105

Answer:

105 square meters

Area= a + b/2 • h

Area= 15 + 6/2 • 10

Area= 21/2 • 10

Avi's pet hamster Chubby loves to run in his hamster wheel. During one "race", Avi counts 1000 rotations of the wheel. She wants to know how far Chubby ran, so she measures the diameter of the wheel and finds that it is 20 cm. How far did Chubby run

Answers

Answer:

i think its 200 m

Step-by-step explanation:

because 20 times 1000 rotations is 20000 cm so when u convert it to meter it is 200 meter if it is km it is 0.2 km

Distance ran by Avi's pet hamster chubby is 6280 cm.

The diameter of hamster wheel = 20 cm
Now the circumference of hamster wheel is given by :-

where d ⇒ the diameter of the hamster wheel.

During one race, the number of rotations of the wheel = 100
Therefore, the distance run by chubby is given by :-
Distance ran by chubby is equal to the number of rotations of the wheel times Circumference of the wheel.
framing in equation form we get;

D⇒ Distance ran by Chubby.

It stretches southward across the largest and northernmost state in the United States, ending at a remote ice-free seaport village nearly 800 miles from where it begins. It is massive in size and extremely complicated to operate. The steel pipe crosses windswept plains and endless miles of delicate tundra that tops the frozen ground. It weaves through crooked canyons, climbs sheer mountains, plunges over rocky crags, makes its way through thick forests, and passes over or under hundreds of rivers and streams. The pipe is 4 feet in diameter, and up to 2 million barrels (or 84 million gallons) of crude oil can be pumped through it daily. Resting on H-shaped steel racks called "bents," long sections of the pipeline follow a zigzag course high above the frozen earth. Other long sections drop out of sight beneath spongy or rocky ground and return to the surface later on. The pattern of the pipeline's up-and-down route is often determined by the harsh demands of the arctic and subarctic climate, the tortuous lay of the land, and the varied compositions of soil, rock, or permafrost (permanently frozen ground). A little more than half of the pipeline is elevated above the ground. The remainder is buried anywhere from 3 to 12 feet, depending largely upon the type of terrain and the properties of the soil. One of the largest in the world, the pipeline cost approximately $8 billion and is by far the biggest and most expensive construction project ever undertaken by private industry. In fact, no single business could raise that much money, so eight major oil companies formed a consortium in order to share the costs. Each company controls oil rights to a particular share of land in the oil fields and paid into the pipeline-construction fund according to the size of its holdings. Today, despite enormous problems of climate, supply shortages, equipment breakdowns, labor disagreements, treacherous terrain, a certain amount of mismanagement, and even theft, the Alaska pipeline has been completed and is operating.Which phrase in the first paragraph mean Supported by?
