Answer:

The slope is 0.55

Step-by-step explanation:

Right Triangles

The string, the ground, and the height of the balloon form a right triangle where the trigonometric ratios are satisfied.

The image below shows the geometric construction. We are required to find the slope the string forms with the ground.

It can be found by using the tangent ratio:

[tex]\displaystyle \tan\theta=\frac{y}{x}[/tex]

Substituting y=30 and x=55

[tex]\displaystyle \tan\theta=\frac{30}{55}[/tex]

[tex]\displaystyle \tan\theta=0.55[/tex]

The slope is 0.55

Explanation:

Sort the values from smallest to largest: {2, 5, 6, 10, 10}

Now cross off the first and last values to get this smaller set: {5, 6, 10}

Repeat the process one more time and we get this: {6}

This shows 6 is the middle most item of the original sorted set above. Therefore, 6 is the median.

Answer:

5

Step-by-step explanation:

15/3 is the same as 5 since 5*3 is 15

Answer:

138.5°

Step-by-step explanation:

Since the peach pie is a circle, we have a total angle of 360°.

We need to determine what fraction of the total pie of 13 peaches is the 5 peaches contained in Joe's slice.

This is number of peaches in Joe's slice/total number of peaches in pie = 5/13. To find the angle Joe's slice measures, we multiply 5/13 by 360°.

So, 5/13 × 360°

= 0.3846 × 360°

= 138.46°

≅ 138.5° to the nearest tenth of a degree

Answer:

x = -6

Step-by-step explanation:

Answer:

x=-6

Step-by-step explanation:

14=-(x-8)

14=−x+8(Distribute)

flip equation:

−x+8=14

Subtract 8 from both sides

−x+8−8=14−8

−x=6

divide by -1 both sides

x=-6

Answer:

The answer is 8

Step-by-step explanation:

I need the good luck :)

let

brenda: b

will: 3b

b + 3b = 240

4b = 240

b = 60 lbs (BRENDA)

3b = will

3 (60) = will

180 = WILL

The solution is

The weight of Brenda = 60 pounds

The weight of Will = 180 pounds

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the weight of Brenda be = x

Let the weight of Will be = y

Now , Will weighs three times as much as Brenda

Substituting the values in the equation , we get

y = 3x   be equation (1)

And , the weight of Will + weight of Brenda = 240 pounds

So , x + y = 240   be equation (2)

Substituting the value of y from equation (1) in equation (2) , we get

x + 3x = 240

On simplifying the equation , we get

4x = 240

Divide by 4 on both sides of the equation , we get

x = 60 pounds

So , the weight of Brenda is 60 pounds

Substitute the value of x in equation (1) , we get

y = 3x

y = 3 x 60

y = 180 pounds

So , the weight of Will is 180 pounds

Hence , the weight of Brenda is 60 pounds and weight of Will is 180 pounds

Answer:

B: x=9

Step-by-step explanation:

You have to use the property of logarithms

that says ln A + ln B = ln AB.  So here we have

ln (3x - 5) = ln 11 + ln 2 = ln 22

Therefore 3x - 5 = 22, from which x = 9

5b=2f

Step-by-step explanation:

Priya uses [tex]7\dfrac{1}{2}[/tex] cups of floor to make 3 loaves of banana bread.

Andre will follow the same recipe. He will make b loaves of banana bread using f cups of flour.

To find the relation between b and f, the steps are as follows :

[tex]\dfrac{\text{cups of flour}}{\text{loaves of banana bread}}=\dfrac{7 \dfrac{1}{2}}{3}\\\\=\dfrac{\dfrac{15}{2}}{3}\\\\=\dfrac{15}{2}\times \dfrac{1}{3}\\\\=\dfrac{5}{2}[/tex]

It means,

[tex]\dfrac{f}{b}=\dfrac{5}{2}\\\\5b=2f[/tex]

So, the relationship between b and f is "5b=2f".

Answer:

b = -12

Step-by-step explanation:

First isolate b by subtracting 2 from both sides: b/4 = -3

then multiply both sides by 4 to find b: b = -12

Answer:

b= -12

Step-by-step explanation:

b/4 + 2 = -1

Subtract 2 from both sides

b/4 = -3

Multiply both sides by 4

b= -12

Answer:

4 bottles of Water

Step-by-step explanation:

First, we need to find how much each water costs. So, I created this equation below.

9/12=?

The answer to the equation is .75, or 75 cents.

So, we can now make yet another equation to find the amount to buy with 3 dollars.

3/.75=?

The answer to that equation is 4.

Thus, the answer is 4 bottles of water.
