I believe the answer is 28/40 which is reduced to 7/10.

It says large OR blue, so i added the total of large + blue, and its out of 40 total so i got 28/40. that reduces to 7/10.

What is the midpoint of line segment AB?

Answers

Answer:

( 3, 5.5 )

Step-by-step explanation:

Let,

( x1, y1 ) = ( 7, 3 )

Where,

x1 = 7

y1 = 3

Let,

( x2, y2 ) = ( - 1, 8 )

Where,

x2 = - 1

y2 = 8

Formula : -

Midpoint = ( x1 + x2 ) / 2, ( y1 + y2 ) / 2

Midpoint of AB

= ( - 1 + 7 ) / 2, ( 8 + 3 ) / 2

= 6 / 2, 11 / 2

= ( 3, 11 / 2 )

= ( 3, 5.5 )

The diagram shows a solid triangular prism. Height 6cm width 4cm length 10cm the prism is made from wood with a density of 0.8 g/cm3 work out the mass of this prism

Answers

Answer:

Step-by-step explanation:

The mass of the given triangular prism with a density of 0.8 g/cm³ is 96 grams.

What is the volume of a prism?

The volume of a prism is the total space occupied by it.

What is the density of a prism?

The density of a prism is the mass occupied by the 1 cubic unit volume of the prism. The formula for the density of a prism is:

Density = Mass/Volume

How do we solve the given question?

In the question, we are given a triangular prism of height 6cm, width 4cm, and length 10cm. Its density is given as 0.8 g/cm³.

We first find the volume of the prism.

The volume = Area of triangle*length = ((1/2)*6*4)*10 cm³ = 120 cm³.

Let the mass of the prism be m grams.

We know the density of the prism is given by the formula,

Density = Mass/Volume

or, 0.8 = m/120

or, m = 120*0.8

or, m = 96

∴ The mass of the given triangular prism with a density of 0.8 g/cm³ is 96 grams.

The volume of the larger sphere is _____π cubic inches greater than the volume of the smaller sphere.

Answers

Answer:

1332 will be the correct answer...

Step-by-step explanation:

first sphere:2304π

AB is parallel to ED.

AB = 8 cm

AC = 4.8cm

BC = 6.4cm

ED = 20 cm

Work out the length of BE.​

Answer:

BE = 22.4 cm

Step-by-step explanation:

Δ CAB and Δ CDE are similar , then ratios of corresponding sides are equal, that is

[tex]\frac{CB}{CE}[/tex] = [tex]\frac{AB}{DE}[/tex] , substitute values

[tex]\frac{6.4}{CE}[/tex] = [tex]\frac{8}{20}[/tex] ( cross- multiply )

Match the steps to factor a polynomial with four terms by grouping. Use grouping to factor 20a4 - 10a3 + 12a2 - 6a.

Answers

Answer:

Step-by-step explanation:

The first two factor as

10a^3 ( 2a - 1)

The second two factor as

6a (2a - 1)

When you put them together, the common factor is 2a - 1

(10a^3 - 6a) (2a - 1)   Can you factor any further? Yes. Try taking out 2a out of the first factor

2a(5a^2 - 3) Now what you have is

2a(5a^2 - 3)(2a - 1)     Don't go any further.

Answer:

2a(2a - 1)(5a^2 + 3)

Step-by-step explanation:

You can start by grouping the terms into two groups:

20a^4 - 10a^3 and 12a^2 - 6a

Next, you can factor them:

(20a^4 - 10a^3) + (12a^2 - 6a)

10a^3(2a - 1) + 6a(2a -1)

Now, you can factor out the expression 2a - 1 to get:

(2a - 1)(10a^3 + 6a)

In the second factor, the two terms have a GCF of 2a, so you can factor that out:

2a(2a - 1)(5a^2 + 3)

A triangle has angles measuring 25 degrees and 45 degrees. What is the measure of the triangle's third angle

Answers

Answer:

110°

Step-by-step explanation:

Let the third angle be x. All the angles in a triangle add up to 180°. From the previous statement, we can write the equation:

25° + 45° + x = 180°

70° + x = 180°

x = 110°

This graph shows time and distance traveled for two objects.

B. Object 2 travels 5/6 of a foot more per minute than object 1.

C. Object 1 travels 6/5 of a foot more per minute than object 2.

D. Object 1 travels 5/6 of a foot more per minute than object 2.

Answers

Object 1 travels 5/6 of a foot more per minute than object 2. Thus option (D) is the correct answer.

What is a graph?

"A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The points on the graph often represent the relationship between two or more things".

For the given situation,

The graph is plotted between time and distance.

The distance is represented as 'd'

The time is represented as 't'

The speed is represented as 's'

The formula for speed is given as speed = distance/time

Now consider object 1 :

Distance, d = 105 feet

Time, t = 70 minutes

Now consider object 2 :

Distance, d = 70 feet

Time, t = 105 minutes

Take the ratio of their speeds.

[tex]s1:s2 = \frac{105}{70}:\frac{70}{105}[/tex]

⇒ [tex]s1:s2 = \frac{3}{2}:\frac{2}{3}[/tex]

⇒ [tex]s1:s2= \frac{9:4}{5}[/tex]

Hence we can conclude that object 1 travels 5/6 of a foot more per minute than object 2. Thus option (D) is the correct answer.
