Marcus and his dad were going camping. When they went into the garage to get their tent they noticed it was ripped. Marcus’s dad said he could fix the tent. He would buy some new material to cover the one rectangular side that ripped.

Answer:

[tex]c=\sqrt{130}\\[/tex]

Step-by-step explanation:

When we solve for this we should always remember this formula [tex]a^2+b^2=c^2[/tex] and since we already know a and b we can plug that in to find out what c could be but we won't actually solve it.

[tex]a^2+b^2=c^2\\7^2+9^2=c^2\\49+81=c^2\\130=c^2\\\sqrt{c^2}=\sqrt{130}\\c=\sqrt{130}[/tex]

So c would equal whatever the square root of 130 is.

Answer:

Answer:

The 80% confidence interval = (41.8, 44.4)

Step-by-step explanation:

From the above question, the random number of samples is 27, this sample size is below 30, hence it is small.

To solve for this, we have use t score instead of confidence interval.

Degrees of freedom = 27 - 1 = 26

t score for 80% confidence interval = 1.315

The 80% confidence interval = Mean ± t score × standard deviation/√n

Mean = 43.1 bushels

Standard deviation = 5.31

Hence,

43.1 ± 1.315 × 5.31/√27

43.1 ± 1.3438116191

Hence:

43.1 - 1.3438116191

= 41.756188381

≈ 41.8

43.1 + 1.3438116191

= 44.443811619

Approximately ≈ 44.4

Therefore, the 80% confidence interval = (41.8, 44.4)

Answer:

The average motorcycle would weigh 32 kilograms.

Step-by-step explanation:

1 kilogram = 1000 grams

so, to find how many kilograms a motorcycle is, we just need to divide the amount of grams by 1000

32,000 / 1000 = 32 kg

Option {C} : a reflection over the y - axis followed by another reflection over the y - axis is the correct alternative of the given ones.

Given is a Rectangle ABCD as shown on the coordinate grid.

In order to map the rectangle ABCD onto itself, we will reflect it over the y − axis followed by another reflection over the same y − axis.

Therefore, option {C} : a reflection over the y - axis followed by another reflection over the y - axis is the correct alternative of the given ones.

Answer:

Lisa borrowed $8,500

Step-by-step explanation:

Simple Interest

Occurs when the interest is calculated on the original principal of a loan only.

Unlike compound interest where the interest earned in the compounding periods is added to the old principal, simple interest only considers the principal to calculate the interest.

The interest earned is calculated as follows:

I=Prt

Where:

I = Interest

P = initial principal balance

r = interest rate

t = time

Lisa took out a loan for t=5 months and was charged simple interest at an annual rate of r=4.8% = 0.048. She paid interest for I=$170.

We need to convert the time to years (there are 12 months per year):

t = 5 /12 years.

The formula must be solved for P:

[tex]\displaystyle P=\frac{I}{rt}[/tex]

Substituting:

[tex]\displaystyle P=\frac{170}{0.048*5/12}[/tex]

[tex]\displaystyle P=\frac{170}{0.02}=8,500[/tex]

Option D: 5√5 is the correct answer.

Step-by-step explanation:

Given that:

√20 + √45

These can also be written in simplified form;

√5*4 + √5*9

We will take square root of 4 and 9.

The square root of 4 and 9 is,

√4 = 2

√9 = 3

Thus,

2√5 + 3√5

Adding the roots,

5√5

Hence,

Option D: 5√5 is the correct answer.

Answer:

1 ft away from the motion detector.

Step-by-step explanation:

To calculate Xavier's distance we can assume that the motion detector would be represented as 0ft. Now we simply need to create the arithmetic expression for every step/action that Xavier performed. Finally, we would solve the expression to calculate Xavier's total distance from the motion detector.

5ft + (0.5ft * 4) + (-2ft * 3)

5ft + 2ft - 6ft

1ft

Finally, we can see that Xavier is 1 ft away from the motion detector.

Answer:

7.2 + 0.8w

Step-by-step explanation:

combine like terms. Like terms have same variable with same power.

2.2w and (-1.4w) are like terms & 4.8 and 2.4 are like terms.

4.8 + 2.2w - 1.4w + 2.4 = 4.8 + 2.4 + 2.2w - 1.4w

                                      = 7.2 + 0.8w

Answer:

7.2+0.8w

Step-by-step explanation:

4.8+2.2w-1.4w+2.4

4.8+2.4=7.2   2.2w-1.4w=0.8w

Answer:

[tex]B = (x+4,y-2)[/tex]

Step-by-step explanation:

Let the current position be A:

[tex]A = (x,y)[/tex]

Required

Determine the new position

First, you move 4 units to the right.

This is represented as [tex]x + a[/tex]

Where a is the number of units to the right

In this case:

[tex]a = 4[/tex]

So, we have: [tex]x + 4[/tex]

Then you move 2 units downwards

This is represented as [tex]y - b[/tex]

Where b is the number of units downwards.

In this case:

[tex]b = 2[/tex]

So, we have: [tex]y - 2[/tex]

So, the new position (B) is:

[tex]B = (x+4,y-2)[/tex]

Answer:

68°

Step-by-step explanation:

Every figure must sum 180°(Sides-2) degrees

Example: For a triangle (3 sides) 180°(3-2) => 180°(1) =>180°

In this case: 5 sides 180°(5-2) => 540°

So all the angles (5) must sum 540°

Mathematically expressed as:

[tex](119)+(z)+(2z)+(70)+(2z)+(11)=540\\119+z+2z+70+2z+11=540\\200+5z=540\\5z=540-200\\5z=340\\z=\frac{340}{5}\\z=68'[/tex]

Lets see changing every Z by 68...

119+68+2(68)+70+2(68)+11

119+68+136+70+136+11=540°
