Answer:

the woodpecker was 7m above the ground

The height where the bird pecked is 7m above the ground.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, A woodpecker pecked at a 17 m wooden pole until it cracked and the upper part fell with the top hitting the ground 10 m from the foot of the pole.

Therefore, If the length of the pole that fell down is 10m then the length of the remaining pole is,

= (17 - 10)m.

= 7m.

So, The bird pecked away where the pole had cracked is 7m.

The number of different ways that 11 books can be arranged on a bookshelf is 39,916,800.

To determine the number of ways the 11 books can be arranged on a bookshelf, we can use the formula for permutation, which is given by:

P(n,r) = n!/(n-r)!

Where n is the total number of items and r is the number of items selected. In this case, we have 11 books and we want to arrange them all, so r = 11.

Therefore, the number of different ways the 11 books can be arranged on a bookshelf is:

P(11,11) = 11!/(11-11)! = 11! = 39,916,800.

This means that there are 39,916,800 different possible ways to arrange the 11 books on the bookshelf.

Answer:

5 and 6

Step-by-step explanation:

The square root of 25 is 5 and the square root of 36 is 6. 33 falls between those

Answer:

f(-3) = 6

Step-by-step explanation:

\(f(-3)=\frac{2}{3} (-3)+8=\frac{2(-3)}{3} +8=-\frac{6}{3}+8= -2+8=6\)

Hope this helps.

Answer:

f(x) = 6

Step-by-step explanation:

f(-3) means replace the x in f(x) with a -3, and replace every x in the equation with -3.

f(-3) = (2/3)x + 8

      = (2/3) (-3) + 8

      = (2 X -3)/3 + 8

      = -6/3   + 8

      = - 2 + 8

Answer:

24 m^2

Step-by-step explanation:

Given data

Length= 4 meters

Width= 2+4= 6 meters

We know that the expression for the area of a rectangle is given as

A= Lenght* Width

A= 4*6

A= 24m^2

Hence the area is 24 m^2

The area of the rectangular parking lot is 929.03 square meters.

Use the formula for the area of a rectangle to calculate the area of the rectangular parking lot, which is given as:

Area = length × width

We know that the parking lot is 67.5 ft wide and 148 ft long, the area can be calculated as follows:

Area = 67.5 ft × 148 f

t= 9990 sq. ft

However, the question asks for the area in square meters, so we need to convert square feet to square meters. 1 square foot is equal to 0.092903 square meters, so we can use this conversion factor to convert square feet to square meters.

Area in square meters = Area in square feet × 0.092903

= 9990 sq. ft × 0.092903

= 929.03 sq meters

Therefore, the area is 929.03 square meters.

Answer:

Step-by-step explanation:

The rate of decrease in volume of the snowball when its diameter is 12 cm is approximately 1.36 cm³/min.

When a spherical snowball is melting, it's diameter decreases at a rate of 0.3 cm/min. The rate of change of volume of a sphere is given by:dV/dt= (4π/3)r²(dr/dt)Since the diameter is given as 12 cm, the radius of the snowball is 6 cm.So the diameter is decreasing at a rate of 0.3 cm/min.

We are to find the rate of decrease in volume of the snowball when the diameter is 12 cm.The radius of the snowball is given by r = 6 cm, and the rate of change of its diameter is d = -0.3 cm/min.At this point, we need to calculate the rate of decrease in volume of the snowball when the diameter is 12 cm.

The rate of decrease in volume of the snowball is given bydV/dt = (4π/3)r²(dr/dt)dV/dt = (4π/3)(6 cm)²(-0.3 cm/min)≈ -1.36 cm³/minTherefore, the rate of decrease in volume of the snowball when the diameter is 12 cm is approximately -1.36 cm³/min.

The areas of the two triangles are 4 square millimeters and 8 square millimeters, and the area of the trapezoid is 12 square millimeters.

First we need to use the formula for the area of a triangle:

Area = 0.5 x base x height

The height of each triangle is 4 mm, and the bases are 2 mm and 4 mm. Therefore, the areas of the two triangles are:

Area of triangle 1 = 0.5 x 2 mm x 4 mm = 4 square millimeters

Area of triangle 2 = 0.5 x 4 mm x 4 mm = 8 square millimeters

To find the area of the trapezoid, we can add the areas of the two triangles together:

Area of trapezoid = Area of triangle 1 + Area of triangle 2

Area of trapezoid = 4 square millimeters + 8 square millimeters

Area of trapezoid = 12 square millimeters

Therefore, the areas of the two triangles are 4 square millimeters and 8 square millimeters, and the area of the trapezoid is 12 square millimeters.

To determine if there is a difference in the mean empathy score between men and women, we can perform a hypothesis test using the data provided. We will use the independent samples t-test since we have two independent groups (males and females) and want to compare their means.

The null hypothesis (H0) states that there is no difference in the mean empathy scores between men and women, while the alternative hypothesis (Ha) states that there is a difference.

Using the given data, we calculate the mean empathy scores for each group and compute the sample means, standard deviations, and sample sizes. With these values, we can use the T1-84 Plus calculator to perform the t-test and obtain the p-value.

If the p-value is less than the significance level (α = 0.05), we reject the null hypothesis and conclude that there is a significant difference in mean empathy scores between men and women. On the other hand, if the p-value is greater than 0.05, we fail to reject the null hypothesis and conclude that there is not enough evidence to support a difference.

By conducting an independent samples t-test and using the p-value method with the given data, we can determine if there is a significant difference in mean empathy scores between men and women.

Amari and Ethan planned an end of season soccer party to purchase 45 hotdogs in 30 individual bags of chips which person will receive the same amount of food what is the greatest number of people they can be without having any leftovers

The correct answer is 15 x + 50 = 300

Explanation:

In an equation, the different values show a specific mathematical relationship, and the equality represented by the symbol (=) is used to find an unknown value. In the case presented, the unknown value is the number of months Elizabeth can pay using her $300 gift certificate. This means the letter x in the equation represents the number of months.

Moreover, this x should be multiplied by the month membership or $15 considering Elizabeth will need to pay this fee each month and this should be added to the one-time fee of $50. This implies the first part of the equation is 15x + 50. Finally, this value should be equal to the total money in the certificate or 300. According to this, the equation is 15x + 50 = 300.

The number of yes votes would be 4,836.

Solution:

Given,

The ratio of yes votes to no votes is 5:6. So, assuming the actual values of yes votes and no votes be 5x and 6x respectively. We can frame an equation as follows,

5x + 6x = 10,640

=> 11x = 10,640

=> x = 967.27272727

So, the number of yes votes would come out to be,

5*967.272727 = 4836.3636

Since the answer can not be a fractional integer,

therefore, we will round it up to 4,836.
