Answer:

45 green beads

.

Step-by-step explanation:

Let the number of red beads be 'x'

Given that, Carrie has 3 times as many green beads as red beads

Number of green beads = 3 times number of red beads

Number of green beads = 3x

She 2 as many blue beads as green beads

Number of blue beads = 2 times the number of green beads

Number of blue beads = 2(3x) = 6x

She has 150 total

Therefore,

Number of red beads + Number of green beads + Number of blue beads = 150

x + 3x + 6x = 150

10x = 150

x = 15

Thus, number of green beads = 3x = 3(15) = 45

Thus there are 45 green beads

I hope this helps

The question requires finding total green beads she has

There are 45 green beads

let

number of red beads = x

number of green beads = 3x

number of blue beads = 2(3x)

Total beads = 150

Total beads = red beads + green beads + blue beads

150 = x + 3x + 2(3x)

150 = 4x + 6x

150 = 10x

divide both sides by 10

x = 150/10

x = 15

Therefore,

number of red beads = x

= 15 beads

number of green beads = 3x

= 3 × 15

= 45 beads

number of blue beads = 2(3x)

= 2(3 × 15)

= 2(45)

= 90

Answer:

1x a other b

Step-by-step explanation:

simple

The equivalent expression is 7x - 2(1.3x + 3.5) = 5.4x - 7 and non-equivalent expression is 8 - 4(-2.2x + 1.1) = 8.8x + 12.4 .

A linear expression only has one or two variables. No variables in a linear expression is raised to power greater than 1 or used as denominator of a fraction.

Now the given expressions are,

7x - 2(1.3x + 3.5) = 5.4x - 7   ....(i)

and,

8 - 4(-2.2x + 1.1) = 8.8x + 12.4     .....(ii)

Taking equation (i)

7x - 2(1.3x + 3.5) = 5.4x - 7

So, LHS = 7x - 2(1.3x + 3.5)

⇒  LHS = 7x - 2.6x + 7

or, LHS = 5.4x + 7

⇒ LHS = RHS

So these expressions are equivalent.

Taking equation (ii),

8 - 4(-2.2x + 1.1) = 8.8x + 12.4

So, LHS = 8 - 4(-2.2x + 1.1)

⇒ LHS = 8 - 8.8x - 4.4

⇒ LHS = -0.8x - 4.4

⇒ LHS ≠ RHS

So these expressions are not equivalent.

Thus, the equivalent expression is 7x - 2(1.3x + 3.5) = 5.4x - 7 and non-equivalent expression is 8 - 4(-2.2x + 1.1) = 8.8x + 12.4.

Answer: 270 inches squared

Answer: angle of w is 115 degrees and angle of y is 65 degrees.

Step-by-step explanation: in the picture.

Answer:

angle W and angle y are supplementary

that is angle W + angle Y = 180°

angle w = 5x + 20

angle y = 4x - 11

putting this value in above equation

we get

5x + 20 + 4x - 11 = 180

5x + 4x + 20 - 11 = 180.

9x + 9 = 180

9x = 180 - 9

9x = 171

x = 19

angle W= 5x + 20

= 5(19)+ 20

= 95 + 20

= 115°

angle y = 4x - 11

= 4(19) - 11

= 76 - 11

= 65

Answer:

below

Step-by-step explanation:

Each column represent the number of packages of pencils and the total number of pencils you would have.

So column 1 says 1/2 package of pencils and there are 24 pencils in that package so you have 12 pencils total not 24 like it says.

Column 2 says 1 package of pencils.  Since there are 24 pencils in a package, now you would have 24 pencils total.

Column 3 says 3 packages.  3 x 24 = 72 pencils total

Column 4 says 4 packages.  4 x 24 = 96 pencils total

Colum 5 says 6 1/2 packages.  6 x 24 = 144 and you know 1/2 of a package equals 12.  So 144 + 12 = 156 total pencils.

Answer: 582 miles per hour

Step-by-step explanation:

581.603 miles per hour

Round= 582

The speed of an airplane in miles per hour is 581.60 miles/hour.

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.

Given the speed of an airplane  = 260 m/sec

Since,

1 mile = 1.60934 kilometer

1 km = 1000 meter

So,

1 mile = 1609.34 meter

1 m = (1/1609.34) mile

And,

1 hour = 360 seconds

1 s = (1/360)hour

So,

260 m/sec = 260 (3600/1609.34) miles/hour

⇒ 581.60 miles/hour.

Hence "The speed of an airplane in miles per hour is 581.60 miles/hour".

Answer:

Elliot is incorrect

Step-by-step explanation:

Let's take an example: 2

Absolute value of 2 = |2| = 2

But the opposite of 2 = -(2) = -2

But 2 ≠ 2, so Elliott is incorrect.

The opposite of a number changes the sign from - to +, or + to -. Absolute value changes the sign of a number from - to + and keeps + as +.

-Chetan K

Answer:

No

Step-by-step explanation:

The absolute value of a number is the distance from 0. Distance is always positive, so the absolute value of a number is that number but positive. Thus, the absolute value of |2| is still 2. However, the opposite of a number is that number on the opposite side of 0. Therefore, the opposite of 2 is -2. To find the opposite of a number just flip the sign.

So, these are different because the absolute value is always positive while the opposite can be either sign.

Answer:

Right scalene triangle

Acute equilateral triangle

Step-by-step explanation:

For the first triangle, we will use the Converse of the Pythagorean Theorem:

If c² < a² + b², then it means that it is an acute triangle.

If c² = a² + b², then it means that it is a right triangle.

If c² > a² + b², then it means that it is an obtuse triangle.

For the first triangle, let c = 25 yd, a = 7 yd, and b = 24 yd

c² = a² + b²

25² = 7² + 24²

625 = 49 + 576

625 = 625 (True statement).

Therefore, the first triangle is a right triangle. At the same time, each angle have different measures, making it a scalene triangle.  Therefore, the first triangle is an example of a right scalene triangle.  

For the second triangle, since all sides are equal, it doesn't matter which side we label as a, b, or c.

Let's see which type of triangle it is according to its sides:

c² = a² + b²

32² = 32² + 32²

1024 < 2048  

Therefore, it is an acute triangle. At the same, the second triangle has equal sides, making it an equilateral triangle. Therefore, the second triangle is an example of an acute equilateral triangle.

Answer: 8 and 7

Step-by-step explanation:

8 multiplied by 7 equals 56

8+8+7+7 equals 30 which is the perimeter

:)

The dimensions of the rectangle whose perimeter is 30 meters and whose area is 56 square meters are 7 meters and 8 meters.

The area of a surface is the total space occupied by the two-dimensional cross-section.

The perimeter of an object is the total length of its boundary.

We are asked to find the dimensions of a rectangle whose perimeter is 30 meters and whose area is 56 square meters.

Let the length and breadth of the rectangle be l meters and b meters respectively.

We know that,

Perimeter of a rectangle = 2(length + breadth) = 2(l + b)

∴ 30 = 2(l + b)

or, 2(l + b) = 30

or, l + b = 15

or, b = 15 - l ...(i)

We know that,

Area of a rectangle = length*breadth = l*b

∴ 56 = l*b

or, l*b = 56

Substituting the value of b = 15 - l from (i) in the above equation, we get:

l(15 - l) = 56

or, 15l - l² = 56

or, l² - 15l + 56 = 0

or, l² - 8l - 7l + 56 = 0

or, l(l - 8) -7(l - 8) = 0

or, (l - 7)(l - 8) = 0

By zero-product law,

Either l - 7 = 0 ⇒ l = 7

Or, l - 8 = 0 ⇒ l = 8.

Substituting these values of l in (i),

b = 15 - l

∴ Either, b = 15 - 7 = 8

Or, b = 15 - 8 = 7.

In both cases, the dimensions of the rectangle are 7, and 8.

∴ The dimensions of the rectangle whose perimeter is 30 meters and whose area is 56 square meters are 7 meters and 8 meters.
