Which decimal is equivalent to 2/9?
A. 2.2
B. 2.9
C. 22222
D. 0.2

Answer:

Question 1 = c) Medium: 88 ft²

Question 2 = d) 46.7 ft³

Step-by-step explanation:

Question 1

We would be solving this question by finding the surface area of the tent. The shape of the tent is a square based pyramid.

The surface area of a square based pyramid(tent) =

a² + 2ah

Where in the diagram,

a = base length = 4 ft

h = height of the pyramid (tent ) = 9ft

Surface area = 4² + 2 × 4 × 9

= 16 + 72

= 88ft²

Therefore, the size tarp should she purchase is Medium: 88 ft²

Question 2

For question 2, from the attached diagram, we can see that the diagram is a square based pyramid.

To calculate the amount of water that would fill the square based pyramid, we would have to find the Volume of the tent(square based pyramid).

The formula for the Volume of the tent(square based pyramid) = 1/3(a²h)

Where a = base edge

h = height of the pyramid.

From the diagram,

a = base edge => 4ft.

From the question,

h = height of the tent is given as how tall the tent is = 8.75ft.

Therefore, 1/3(a²h)

1/3 × (4ft)²× 8.75ft

= 46.67ft³

Approximately = 46.7ft³

Therefore, the amount of water it would it take to fill the tent, if the tent is 8.75 ft tall is 46.7ft³

Final answer:

The slope of line e, which is perpendicular to line d with a slope of -7/4, is 4/7.

Explanation:

The slope of line d is -7/4. To find the slope of a line perpendicular to d, we use the property that the product of the slopes of two perpendicular lines is -1. So, the slope of line e is the negative reciprocal of -7/4.

To find the negative reciprocal, we find the reciprocal by flipping the fraction and then negate it by changing the sign. Therefore, the slope of line e is 4/7.

Answer:

James has 20 more coins than Reggie

Step-by-step explanation:

Given:

Total number of coins with James and Reggie = 60

If James would agree to give 1/4 of his coins to Reggie, they would then have exactly the same number of coins

To find: number of coins with James and Reggie

Solution:

Let x denote number of coins with James and y denote number of coins with Reggie.

According to question,

[tex]x+y=60\\x-\frac{x}{4} =y+\frac{x}{4} \\x-y=\frac{2x}{4} \\x=2y[/tex]

Put [tex]x=2y[/tex] in [tex]x+y=60[/tex]

[tex]2y+y=60\\3y=60\\y=\frac{60}{3}=20\\ x=2y=2(20)=40[/tex]

So,

number of coins with James = 40

number of coins with Reggie = 20

James has 20 more coins than Reggie

Answer:

448 subscribers use more than 15 hours per week

Step-by-step explanation:

In this question, we shall be using the proportion of what was gotten from a survey to estimate the number of subscribers that use more than 15 hours per week

From the question, we can see that out of the 50 people surveyed, 28 use more than 15-hours per week based on data

The proportion that thus use 15-hours per week based on data is 28/50

Now to know the number of subscribers out of 800 that use more than 15-hours per week based on data we have ; 28/50 * 800 = 28 * 16 = 448 subscribers

Answer:

170

Step-by-step explanation:

The distance between 120 and -50 on a number line is equal to 170.

In Mathematics and Euclidean Geometry, a number line is a type of graph that is composed of a graduated straight line, which typically comprises both negative and positive numerical values that are located at equal intervals along its length.

This ultimately implies that, every number line would primarily increase in numerical value towards the right from zero (0) and decrease in numerical value towards the left from zero (0).

Based on the information provided above, we would determine the distance between the two numerical values 120 and -50 by using the number line as follows:

x = 120 - (-50)

x = 120 + 50

x = 170.

Answer: 0.6%

Step-by-step explanation:

We have a selection of 5 numbers, in those selection we have 3 combinations of 3 consecuitve numbers (because the numbers must be in correct order).

The first 3

The 3 in the middle

the last 3.

So a contestant has 3 combinations were he wins.

Now, the number of possible combinations of the 9 numbers given is:

For the first number we have 9 options.

For the second number we have 8 options (because we already selected one)

For the last number we have 7 options (because we already selected 2 numbers)

Then the number of possible combinations is

10*9*8 = 504

The probabilty of winning will be equal to the number of combinations that the contestant has (3) divided by the total number of combinations, this is:

p = 3/504 = 0.006 or 0.006*100% = 0.6%

[tex]\frac{dB}{dt}=4[/tex]

Step-by-step explanation:

Derivative indicates rate of change of dependent variable with respect to independent variables. It indicates the slope of a line that is tangent to the curve at the specific point.

Given:

Number of bees is modeled by the function [tex]B(x)=50\sqrt{k}+2x[/tex]

The daily high temperature is increasing at a rate of 2 °F per day when  the number of bees spotted is 100.

To find:

rate of change of number of bees when 100 bees are spotted

Solution:

[tex]B(x)=50\sqrt{k}+2x[/tex]

Differentiate with respect to t,

[tex]\frac{dB}{dt}=0+2(\frac{dx}{dt}) \\\frac{dB}{dt}=2(\frac{dx}{dt}) \\[/tex]

Put [tex](\frac{dx}{dt}) =2[/tex]

[tex]\frac{dB}{dt}=2(2)=4[/tex]

At x = 100, [tex]\frac{dB}{dt}=4[/tex]

The equation is rearranged so that \(y\) is expressed in terms of[tex]\(x\): y= 5x - 26[/tex]

To rearrange the given equation so that x is the independent variable, you need to solve for y. Here's how you can do it step by step:

1. Start with the given equation:

[tex]\[y + 6 = 5(x - 4)\][/tex]

2. Expand the right side of the equation:

[tex]\[y + 6 = 5x - 20\][/tex]

3. Move the constant term (6) to the right side by subtracting 6 from both sides:

[tex]\[y = 5x - 20 - 6\]\\y = 5x - 26\][/tex]

Now, the equation is rearranged so that \(y\) is expressed in terms of[tex]\(x\): y= 5x - 26[/tex]
