Answer:

[tex]\sqrt{54}[/tex] and [tex]\sqrt{120}[/tex]

Step-by-step explanation:

If a number 'x' is a perfect square, then [tex]\sqrt{x}[/tex] is rational.

25, 36 and 81 are perfect squares, but 54 and 120 aren't, so the irrational values are [tex]\sqrt{54}[/tex] and [tex]\sqrt{120}[/tex]

Answer:

Square root of 54 and square root of 120

Answer:

  21.6 years

Step-by-step explanation:

The first statement tells you the account balance can be modeled by ...

  A = 440(2)^(t/8) . . . . . where t is in years

We want to find t when A = 2860

  2860 = 440(2^(t/8))

  6.5 = 2^(t/8) . . . . . . . . . . divide by 440

  log(6.5) = (t/8)log(2) . . . . take logarithms

  t = 8·log(6.5)/log(2) ≈ 21.604 . . . . . . divide by the coefficient of t; evaluate

It would take about 21.6 years for the value to reach $2,860.

Answer:

The missing side length is 24.98 units

Step-by-step explanation:

Given

The attached right-triangle

Required

The length of the missing length

Let the missing length be x.

Apply Pythagoras theorem

[tex]Hyp^2 = Opp^2 + Adj^2[/tex]

This gives

[tex]43^2 = 35^2 + x^2[/tex]

[tex]1849 = 1225 + x^2[/tex]

Collect like terms

[tex]x^2 = 1849 - 1225[/tex]

[tex]x^2 = 624[/tex]

Take square roots of both sides

[tex]x = \sqrt{624[/tex]

[tex]x = 24.98[/tex] --- approximated

Step-by-step explanation:

Answer:

area of a trapezoidal base  of each prism with heights  6 and 8 units are 4 square units and 3 square units respectively

Step-by-step explanation:

Let us first be aware of formula of volume for any regular geometrical figure.

Fundamental formula for  volume for any regular geometrical figure is.

volume = area of cross section of object*  height of object (A)

In the problem stated area of cross section of object will be  area of a trapezoidal base.

Given in the question is

Volume of both the trapezoidal prisms = 24 cubic units

*************************************************************************************

For prism with height 6 unit

Substituting the value of height and volume in formula for trapezoidal prisms

24 = 6 * area of a trapezoidal base

=> area of a trapezoidal base = 24/6 = 4 square units

*************************************************************************************

For prism with height 8 unit

Substituting the value of height and volume in formula for trapezoidal prisms

24 = 8 * area of a trapezoidal base

=> area of a trapezoidal base = 24/8 = 3 square units

*************************************************************************************

Therefore area of a trapezoidal base  of each prism with heights  6 and 8 units are 4 square units and 3 square units respectively.

Answer:

56m²

Step-by-step explanation:

separate shape into 2 shapes (i did 1 rectangle at top and 1 square at bottom.

find area separately so for rectangle, it would be 4x10 = 40m²

square = 4x4 = 16m²

then add together areas

16 + 40 = 56m²

Answer:

The total area is 56m²

Step-by-step explanation:

First divide the figure into two different parts; now we have a square and a rectangle. The square has a height of 4 and width of 4 so multiply both numbers to get your area. The rectangle has a height of 4 and an unknown width, with the information we have we know the width of the rectangle has at least 3m² on one side and 3m² on the other. Where we divided the figures we   see the bottom width of the square is 4 which is the missing length to complete the rectangles width. Add 3 plus 3 plus 4 and you have your width. Since now we know that the width of the rectangle is 10 we can use the formula to get the area: 10 times 4 equals 40 the area of the rectangle is 40m².

Area of square: 16m²

Area of rectangle: 40m²

Add the areas of both shapes and that makes the area of the shape previously shown.

The total area is 56m²

Answer:

[tex]f + e + d = 360^o[/tex]

Step-by-step explanation:

The question is incomplete, as what is required is not stated and the triangle is not given.

So, I will solve generally.

The proof is as follows (see attachment for triangle)

From the attachment, we have:

[tex]a + f = 180[/tex]

[tex]b + e = 180[/tex]

[tex]c + d = 180[/tex]

Make f, e and d the subject

[tex]f = 180 - a[/tex]

[tex]e = 180 - b[/tex]

[tex]d = 180 - c[/tex]

Add up the equations

[tex]f + e + d = 180 -a + 180 - b + 180- c[/tex]

Collect like terms

[tex]f + e + d = 180 + 180+ 180-a- b - c[/tex]

[tex]f + e + d = 540-a- b - c[/tex]

We have:

[tex]f + e + d = 540-(a+ b + c)[/tex]

[tex]a + b + c \to 180[/tex] --- angles in a triangle

So, we have:

[tex]f + e + d = 540-180[/tex]

[tex]f + e + d = 360^o[/tex] --- proved

Answer:

37 sin 22 degrees = 12.53

use Pythagorean theorem

  28,728.15 g

Step-by-step explanation:

(11.5 gal) × (3.785 L/gal) × (1000 mL/L) × (0.66 g/mL) = 28,728.15 g

That's 28,700 g rounded to 3 significant figures.

Answer:

i think it would be $80 (brainliest??)

Step-by-step explanation:

jane had a total of $200 BEFORE she spent on 2 games

1. $40

2. $40

3. $40

4. $40

5.$40

2 games = $80

3 games = $120 (money she had left)

You can add the four distances to get the total distance.

9+72+9+11.8= 101.8 total kilometers

***If you are looking for an average run per day, you would then take the total of 101.8 and divide it by 3 days (which would be 33.9 average kilometers run in 3 days).

im not sure if u mean "11.8"

Find the actual Dimensions of the triangle.

Multiply the size of the triangle on paper by 1.5 feet per inch:

Width = 5 x 1.5 = 7.5 feet.

Height= 7 x 1.5 =10.5 feet

Area of a triangle is 1/2 x base x height:

Area = 1/2 x 7.5 x 10.5 = 39.375 square feet.

Answer: 39.375 square feet.

The area of the actual banner is 39.375 feet²

Scaling is used to increase or decrease the size of a figure so as to create an image.

Given that 1 inch on the drawing Is equivalent to 1.5 feet on the actual banner, hence:

Base = 5 in * 1.5 feet per in = 7.5 feet

Height = 7 in * 1.5 feet per in = 10.5 feet

Area of the actual banner = (1/2) * 7.5 * 10.5 = 39.375 feet²

The area of the actual banner is 39.375 feet²

Step-by-step explanation:

to find the mean sum all observation and divide by the number of observations.

Step-by-step explanation:

Answer:

x = 29

Step-by-step explanation:

Given:

m<PQS = 107°

m<RQS = 49°

m<PQR = (2x)°

Required:

Value of x

Solution:

m<RQS + m<PQR = m<PQS (angle addition postulate)

Plug in the values

49 + 2x = 107

Subtract 49 from each side

2x = 107 - 49

2x = 58

Divide both sides by 2

x = 58/2

x = 29

Answer:

42.5 units²

Step-by-step explanation:

Total height of rectangle = 3.5 + 2 = 5.5 units

Total area (without triangles removed) = 5.5 x 9.0 = 49.5 units²

The measurements and area of the triangles removed are equal to those on the diagram, so calculate the area of the triangles and subtract them from the total area.

Left: (0.5)(2)(2) = 2 units²

Right: (0.5)(5)(2) = 5 units²

Area: 49.5 - 2 - 5 = 42.5 units²
