Answers

Solution:

To find the area of a composite shape, we need to break the composite shape into smaller "known" shapes.

⇒ Area of composite figure = Area of quarter circle + Area of all rectangles...

Step-1: Find the radius of the quarter circle

Radius of quarter circle = (8 + 4 + 4) - (9)Radius of quarter circle = (16) - (9)Radius of quarter circle = 7 meters

Step-2: Find the area of the quarter circle (Q)

Area of circle = πr²Area of quarter-circle = πr²/4Area of quarter-circle = (3.14)(7²)/4Area of quarter-circle = (0.785)(49)Area of quarter-circle = 38.465 m²

Step-3: Find the area of rectangle₁ (L)

Area of rectangle = LBArea of rectangle₁ = (21)(8)Area of rectangle₁ = 168 m²

Step-4: Find the area of rectangle₂ (M)

Area of rectangle = LBArea of rectangle₂ = (4 + 4)(21 - 18)Area of rectangle₂ = (8)(3)Area of rectangle₂ = 24 m²

Step-5: Find the area of rectangle₃ (S)

Area of rectangle = LBArea of rectangle₃ = (4)(8)Area of rectangle₃ = 32 m²

Step-6: Find the area of the composite figure.

Area of composite figure = Area of quarter circle + Area of all rectangles...Area of composite figure = 38.465 + (168 + 24 + 32)Area of composite figure = 262.465 m²

The sum of three consecutive numbers is 45. What are the three numbers? Write an equation and solve

Answers

Answer:

14 + 15 + 16 = 45 . Let the three consecutive integers be x, x+1 and x+2. Therefore the numbers would be 14, 15 & 16. answer: 14, 15 and 16.

Step-by-step explanation:

Call n the first integer so you get:

[tex]n + ( n + 1 ) + ( n + 2 ) = 45[/tex]

[tex]3 n + 3 = 45[/tex]

[tex]3 n = 42[/tex]

[tex]n = 14[/tex]

The integers are: 14 , 15 , 16

A home furnishing store sells 6 chairs for $900. Martin buys 2 such chairs for her new home. How much did she spend on the purchase?

Answers

$300 if it is $900 for 6 chairs

if it is $900 each(expensive chairs), it would be $1800

Answer:

$300

Step-by-step explanation:

It would be $300 dollars for 2 chairs because $900 dollars divided by 6 = 150 so each chair is $150. Since we are buying 2 chairs it would be 150 time 2 which equals 300. So she spent $300 on her purchase.

Select all correct answers.

It is an obtuse triangle.

The third angle measures 70°.

Two sides have the same length.

The third angle measures 110°.

It is an acute triangle.

All sides have different lengths.

Answers

Two sides have the same length
The third angle measures 70°
It is an acute triangle.
i know that because eat triangle is 180°, so
if we subtract 40° and 70° from 180°, we get
70°, meaning the three angles in the
triangle are 40°, 70°, and 70°. Because all of
the angles are under 90°, we know that it is
an acute triangle.

Simple-r Answer:

-The third angle measures 70°
-Two Sides have the same length
-It is an acute triangle

Answers

Rounding Decimals When Dividing. You can divide decimals by whole numbers and use zero placeholders to find the most accurate quotient.

What is inequality?

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

The sample of the red candies in the bag:

Red: 2 1 4 2 1 2 1 0 1 3 3 1

Total = 21 red candies in the bags.

There are only 3 green candies in the 1-pound bag.

So, 21 > 3.

Therefore, the number of red candies in the bag is greater.

find the areas of the trapezoid

Answers

Answer:

Formula for the area of a trapezoid;

A = 1/2 (b1 + b2) x h

Where b1 represents base one, and b2 is base two. And H displays as the height.

First, we must figure out our bases and then our height.

If we look at the trapezoid, we can see the bottom base(which will be our base 1) is 4. Our upper base is 2, which we will consider our base 2.

Our height is 4, because the distance between our bases is 4.

So now we plug these values into our formula;

A = 1/2 (b1 + b2) x h

A = 1/2 (4 + 2) x 4

Now solve:-

A = 1/2(6) x 4

A = 6/2 x 4

A = 3 x 4

A = 12

Answer:

48 inches

Step-by-step explanation:

It is going by 2 so when you look at the lines inside the shape going up and down you see 4 lines. 4 times 2=8( because it is going by 2). Then you see the lines in the shape going horizontal it states 2 lines is equal to 2 so then you do 2 times 2=4(because it is going by two). You then do 8 times 4=32 and 8 times 2=16 32+16=48. I go to RSM too so trust me this is correct.

Answers

-3x + 7 = -1
-3x = -8
x = 8/3

In order to solve for x, you must isolate the variable. Because -1 and 7 are like terms, use inverse operations to subtract 7 from both sides. Then, divide both sides by -3. This should get you x = 8/3, which can’t be reduced any more (unless you convert to decimal, which is about 2.666666…) Feel free to comment any questions you have! Always happy to help :)
