Carrie is making a colorful beaded necklace. She has 3 times as many green beads
as red beads, and twice as many blue beads beads. If she has 150 beads
all together, how many of the beads are green?

Answers

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

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 .

What are linear expression ?

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.

1/2=12, 1=24, 3=72, 4=96, 6 1/2=156

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.

angle W and angle Y are supplementary. If
the measure of angle W = 5x + 20 and the measure of angle Y = 4x - 11, find the measure of angle W
and Y

Answers

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

Step-by-step explanation: in the picture.

Answer:

Angle W = 115° Angle Y = 65°

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

Reggie records the lengths of different fabrics he has.

Answers

1/8+1/4+3(1/2)+2(5/8)+4(3/4)=49/8
49/8-11/4=27/8

Reggie is left with [tex]\dfrac{27}{8}[/tex] yarns of fabric.

The total length of fabrics =  [tex]\dfrac{1}{8}+\dfrac{1}{4}+3\dfrac{1}{2}+2\dfrac{5}{8}+4\dfrac{3}{4}[/tex]

                                            =  [tex]\dfrac{1}{8}+\dfrac{1}{4}+\dfrac{7}{2}+\dfrac{21}{8}+\dfrac{19}{4}[/tex]

The LCM of 4 and 8 is 8.

So, the expressions will be simplified by adding all the terms with the same denominator.

                      = [tex]\dfrac{49}{8}[/tex]

The fabric used by Reggie = [tex]2\dfrac{3}{4}[/tex]

                                              = [tex]\dfrac{11}{4}[/tex]

The fabric left can be calculated by subtracting the total fabric he used from the total fabric he had.

Fabric left =[tex]\dfrac{49}{8} - \dfrac{11}{4}[/tex]

The LCM of 8 and 4 is 8

Fabric left = [tex]\dfrac{49}{8} - \dfrac{22}{8}[/tex]

                 =  [tex]\dfrac{27}{8}[/tex]

So, he is left with [tex]\dfrac{27}{8}[/tex] yarns of fabric.

Hi everyone, stay safe, I need help on this, it’s about Triangles.

Answers

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.

What is unit conversion?

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".
