Answer: 6396

Step-by-step explanation:

Delta math

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"

Answer:

Lower confidence boundary = 134.525

μ ≥ 134.525

Step-by-step explanation:

From the data:

Sample size, n = 153

Sample mean, xbar = 135.39

Standard deviation, s = 4.59

Zcritical at 99% = 2.33 (one sided)

Confidence interval :

Xbar ± standard Error

Standard Error = Zcritical * s/√n

Standard Error = 2.33 * 4.59/√153 = 0.865

Lower boundary:

Xbar - standard error

135.39 - 0.865 = 134.525

μ ≥ 134.525

We Can be 99% confidence that the true average ultimate tensile strength is atleast 134.525

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

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:

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]\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

Step-by-step explanation:

Answer:

37 sin 22 degrees = 12.53

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:

YESSSSS

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:

The missing side length is 24.98 units

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

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.
