Answer:

1.5 as fraction it is  3/2 in simplest form

Step-by-step explanation:

The simplest form of the expression given is 3/2

A mathematical statement containing variables, numbers and connected by a mathematical operator is called an expression.

Given that, an expression  [tex]4\frac{1}{5}[/tex]  × [tex]\frac{5}{14}[/tex]

We are asked to simplify them,

[tex]4\frac{1}{5}[/tex]  × [tex]\frac{5}{14}[/tex]

= 21 / 5 × 5 / 14

= 21 / 14

= 3/2

Hence, the simplest form of the expression given is 3/2

Answer: 191.75 quarts.

Step-by-step explanation:

We know that:

1 quart = 4 cups.

Then:

1 cup = 1/4 quarts.

this means that 1 cup, is equal to 1/4 quarts.

Then 767 cups is equal to 767 times 1/4 quarts.

The change of units is simply:

767 cups = 767*( 1/4 quarts) = 191.75 quarts.

Answer: The one filled with wooden cubes.

Step-by-step explanation:

First, the box filled with spheres will have empty space, this is for how spheres are, so independent of the radius of the sphere, we will always have some empty space inside the box.

In the case of the cubes, this does not happen. Furthermore, the dimension of the box are 8cm by 8cm by 8cm, and the cubes have a sidelength of 1.6cm

We know that:

1.6cm*5 = 8cm

Then we can perfectly fill the box with the wooden cubes (such that there is no empty space like in the previous case).

Because this box has no empty space and is filled with the same material as the other box, we can conclude that this box will have a larger mass than the one filled with spheres.

And we know that:

density = mass/volume.

Both boxes have the same volume, but the box with cubes has a larger mass, then the box with cubes will have a larger density.

2x-5=4

2x=9

x=4.5

Answer:

v = 38

Step-by-step explanation:

A parallelogram is a quadrilateral in which both sides are the same. That means that 2v is equal to v + 38, and you can solve this. You would get that 2v = v + 38, which means that v = 38.

Answer:

This is the subtraction method

Y -3X = -10

(-Y -2x = -5)  -Y + 2X = 5

Y -3X = -10

-Y + 2X = 5

      -X = -5

X = 5  Now fill in the 5 for X and Y =  5

Answer:

x = 5, y = 5

or

(5, 5)

Step-by-step explanation:

they both equal y so they also equal each other.

3x - 10 = 2x - 5

3x - 2x = -5 + 10

x = 5

substitute x for 5

y = 3x - 10

y = 15 - 10

y = 5

edit, whops forgot to check

just plug the variables in with their values and see if it makes sense:

y = 2x - 5

5 = 2*5 - 5

5 = 10 - 5

5 = 5

since 5 does equal 5, the solution is correct.

Answer:

∠A = 62°

Step-by-step explanation:

∠ACB = 180 - 116 = 64°

∠A + ∠B + ∠C = 180°

(3x - 13) + (2x + 4) + 64 = 180°

3x + 2x - 13 + 4 + 64 = 180°

5x + 55 = 180°

5x = 180 - 55

5x = 125

x = 125/5

x = 25

∠A = 3x - 13

∠A = 3(25) - 13

∠A = 75 - 13

∠A = 62°

Answer:

It's 5, or to find it, 3x =15

Answer:

Tn = 8n - 2

Step-by-step explanation:

Given the arithmetic sequence

6, 14, 22, 30, 38

The nth term is expressed as;

Tn = a +(n-1)d

a is the first term = 6

d is the common difference = 14 - 6 = 22 - 14 = 8

Substitute into the formula;

Tn = 6 + (n-1)(8)

Tn = 6 + 8n-8

Tn = 8n - 2

Hence the nth term of the sequence is 8n-2

Step-by-step explanation:

First question already answered in other post.

Second Question:

Original price before discount and tax: $354

Discount: 15%

100% - 15% = 85% = 0.85

0.85 * $354 = $300.90

Tax: 7.8%

100% + 7.8% = 107.8% = 1.078

1.078 * $300.90 = $323.37

Answer:

-5

Step-by-step explanation:

To find the perpendicular line, first rearrange this into slope intercept form.

y= mx + b

2x - 10y = 100

-10y = -2x +100

y = 1/5x - 10

The slope of a perpendicular line has a slope that is the receipt I’ll of and opposite of this line. The slope here is 1/5 so flip it and you have 5/1. It will also be negative since that slope was positive.

1/5 —> 5/1 —> -5
