Answer:

42

Step-by-step explanation:

Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is

90−48=42

The length up the wall does the ladder reach is 2.59 meter

In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.

A right triangle or right-angled triangle, or more formally an orthogonal triangle, is a triangle in which one angle is a right angle or two sides are perpendicular.

Given,

Length of the ladder = 2.9 meter

Distance from base to wall = 1.3 meter

Draw the figure using the given data

Apply Pythagorean theorem

[tex]AB^{2}+BC^{2}= AC^{2}\\ AB^{2}=AC^{2}-AC^{2} \\ AB^{2}=2.9^{2}-1.3^{2}\\ AB^{2}=6.72\\ AB=\sqrt{6.72}[/tex]

AB=2.59 meter

Hence, the length up the wall does the ladder reach is 2.59 meter

Answer:

A. Multiply 3x−3y=1 by 2, and multiply −2x+4y=2 by 3.

Step-by-step explanation:

Given

[tex]3x - 3y = 1[/tex]

[tex]-2x+ 4y = 2[/tex]

Required

A good first step

A good first step is to eliminate x and this is done as follows:

Multiply [tex]3x - 3y = 1[/tex] by 2 (gotten from coefficient of x in the second equation)

Multiply [tex]-2x+ 4y = 2[/tex] by 3 (gotten from coefficient of x in the first equation)

This gives:

[tex]6x - 6y = 2[/tex]

[tex]-6x + 12y = 6[/tex]

Add both equations

[tex]6x - 6x - 6y + 12y = 2 + 6[/tex]

[tex]6y = 8[/tex]

[tex]y = \frac{4}{3}[/tex]

Hence (a), is true

Given:

Some boxes are fully colored.

Each fully colored ten block represents 1 whole.

The number of colored boxes will be divided into 11 equal part.

To find:

The number of squares need to be colored on each of the 10 blocks.

Step-by-step explanation:

From the given figure, it is clear that,

Number of colored box = 55

The number of colored box will be divided into 11.

[tex]\dfrac{55}{11}=5[/tex]

Therefore, 5 squares need to be colored on each of the 10 blocks.

Answer:

$3283.2

Step-by-step explanation:

Given data

Principal= $2700

Rate= 4%

Time= 5 years

Required

the final Amount A

The compound interest formula is

A=P(1+r)^t

Substitute

A=2700(1+0.04)^5

A=2700(1.04)^5

A=2700*1.216

A=$3283.2

Hence the balance in the account after 5 years is $3283.2

Answer:

3. is triangle (3 sides)

4. is pentagon (5 sides)

5. hexagon (6 sides)

Answer:

(a) [tex]Area = 154m^2[/tex]

(b) [tex]Remaining\ portion = 821m^2[/tex]

(c) [tex]Cost = 4105[/tex]

Step-by-step explanation:

Solving (a): The area of the flower bed

Given

[tex]r = 7m[/tex]

[tex]\pi = 22/7[/tex]

The area is:

[tex]Area = \pi r^2[/tex]

[tex]Area = 22/7 * 7^2[/tex]

[tex]Area = 154m^2[/tex]

Solving (b): The area of the remaining portion

Given

[tex]Length= 65m[/tex]

[tex]Width = 15m[/tex]

First, we calculate the field area

[tex]Area = Length * Width[/tex]

[tex]Area = 65m * 15m[/tex]

[tex]Area = 975m^2[/tex]

Subtract the area of the flower pot from the filed area to get the area of the remaining portion

[tex]Remaining\ portion = 975m^2-154m^2[/tex]

[tex]Remaining\ portion = 821m^2[/tex]

Solving (c): The cost of leveling the remaining field

Given

Rate = 5 per square meter

In (b) above, the area is 821m^2

So, the cost will be:

[tex]Cost = 821 * 5[/tex]

[tex]Cost = 4105[/tex]

Answer:

y ≈ 88.54207824°

Step-by-step explanation:

Law of Sines Formula:

[tex]\frac{sinA}{a} = \frac{sinB}{b}[/tex]

[tex]\frac{sin 51}{83} = \frac{sin 56}{y}\\y = \frac{sin 56 * 83}{sin 51}[/tex]

y ≈ 88.54207824°

Answer:

22 degrees

Step-by-step explanation:

Just do arccos(0.9272) on your calculator or just do 90 minus 68.

Answer:

sin 15° = 0.2588

Step-by-step explanation:

The half angle formula is:

[tex]\sin{(\frac{x}{2})} = \pm \sqrt{\frac{1 - \cos{x}}{2}}[/tex]

sin 15°

The double of 15º is 30º. First quadrant, so the sine is positive.

[tex]\sin{15} = sqrt{\frac{1 - \cos{30}}{2}}[/tex]

Since [tex]\cos{30} = 0.866[/tex]

[tex]\sin{15} = sqrt{\frac{1 - \cos{30}}{2}} = \sqrt{\frac{1 - 0.866}{2}} = 0.2588[/tex]

sin 15° = 0.2588

Answer:

10 carrots

Step-by-step explanation:

So we have 6:8 which is 3:4, meaning that something needs to be changed

Solve for x assuming that we have 6 cabbages

1/3=6/x

x=18

Now we have 6:18, which is 1:3 simplified

There are already 8 carrots so subtract 8

18-8=10
