what is the value of x?

Answers

Answer 1

Answer:

k=10

Step-by-step explanation:

The reason is that we should solve the following equation:

4k+5 + 6k+10 + (180-115) = 180

by doing some basic algebra we get:

10k = 100

thus: k=10

Matt wants to start zip line 16 feet high in one tree and end 10 feet high in the other tree is the difference in height sufficient to meet the slope constraint? Use specific numbers from the situation to justify or refute whether Matt’s design meets the slope constraint

Answers

There is no difference in height that is not sufficient to meet the slope constraint if Matt wants to start a zip line 16 feet high in one tree and end 10 feet high in the other tree is the difference in height sufficient to meet the slope constraint.

What is the slope?

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

We know the slope can be evaluated using:

[tex]\rm Slope = \frac{Change \ in \ y \ axis}{Change \ in \ x \ axis}[/tex]

Change in y-axis = difference in height

Change in y-axis = 16 - 10

= 10 feet

Change in x-axis = distance between tress

Since the data is not given.

So, the height difference is insufficient to keep the slope constraint.

Thus, there is no difference in height that is not sufficient to meet the slope constraint if Matt wants to start a zip line 16 feet high in one tree and end 10 feet high in the other tree is the difference in height sufficient to meet the slope constraint.

Steps:
Formula for the area of a triangle.
A = B*H/2

Formula for the area of a rectangle.
A = L*W

1. Break up the shape into 1 triangle and 1 rectangle.

2. The length of the rectangle is 8 ft and the width is 3 ft. Plug-in these values into the formula for the area of a rectangle.

A = 8 * 3
A = 24

3. The base of the triangle is 8 ft and the height is 4 ft. Plug-in these values into the formula for the area of a triangle.

A = (8 * 4) / 2
A = 32 / 2
A = 16

4. Now add the two areas together to find the amount of carpet needed.

24 + 16 = 40

Answer:

38 ft²

Step-by-step explanation:

You can take it as combination of two figures, a trapezoid and a triangle.

Trapezoid has bases 12 ft and 8 ft and height 3 ft

Its area is

A = 1/2(8 + 12)(3) = 30 ft²

Triangle has height 4 ft and base 4 ft,

Its area is

A = 1/2(4*4) = 8 ft²

Total area is

30 + 8 = 38 ft²

A quadrilateral has two angles that measure 222° and 81°. The other two angles are in a ratio of 6:13. What are the measures of those two angles?

Answers

[tex]\sf\huge\underline{\star Solution:-}[/tex]

[tex]\rightarrow[/tex] Ratio of two angles are 6:13.

So, let the one angle be [tex]\sf{6x}[/tex] and another be [tex]\sf{13x.}[/tex]

As we know that,

Sum of all interior angles of a quadrilateral = [tex]\sf\pink{360°.}[/tex]

So let's sum up the given angles,

[tex]\rightarrow[/tex] [tex]\sf{222°+81°+6x+13x \:=\: 360°}[/tex]

[tex]\rightarrow[/tex] [tex]\sf{303+19x \:=\: 360°}[/tex]

[tex]\rightarrow[/tex] [tex]\sf{19x \:=\: 360-303}[/tex]

[tex]\rightarrow[/tex] [tex]\sf{19x \:=\: 57}[/tex]

[tex]\rightarrow[/tex] [tex]\sf{x \:=\: \frac{19}{57}}[/tex]

[tex]\rightarrow[/tex] [tex]\sf{x \:=\: 3}[/tex]

Hence, [tex]\sf{x \:=\: 3}[/tex]

So, First angle [tex]\sf{= \:6x\: = \:6×3 \:=}[/tex] [tex]\sf\purple{18°.}[/tex]

Second angle [tex]\sf{= \:13x\: = \:13×3 \:=}[/tex] [tex]\sf\purple{39°.}[/tex]

Mya and Ashley are buying tickets to the art show. Adult
tickets cost $3 more than the student tickets. Mya buys 7
tickets and 6 adult tickets. Ashley buys 15 student tickets and
1 adult ticket. They both spend the same amount of money
on their tickets. What is the price of one adult ticket?

Answers

Answer:

Step-by-step explanation:

a: adult tickets

s: student tickets

Mya: 7s + 6(3+s)

Ashley: 15s + 1(3+s)

Mya: 7s + 6(3+s) –> 7s + 18 +6s –> 13s +18

Ashley: 15s + 1(3+s) –> 15s + 3 + s –> 16s +3

13s + 18 = 16s +3

15 = 3s, divide 3 from both sides so s = 5

so students tickets cost $5

since adult tickets cost $3 more than student tickets:

($3 + $5) = $8 for an adult ticket.

the answer is $8

Solve using the Elimination Method

6x - y = 7

Answers

Answer:

x=1,y=-1

Step-by-step explanation:

To use the elimination method, we make the coefficient of y the same:

But they are already the same just with different signs.

So we add the 2 equations to make equation 3:

5x + y = 4

+ + = +

6x - y = 7

11x = 11

Solve for x:

x = 1

Substitute the value of x into either equation 1 or 2 to find y:

I chose 1:

5(1)+y=4

5+y=4

y=4-5

y=-1

Our answer is x=1,y=-1

About 50 cane toads were introduced into Australia in 1935 to try to control the population of beetles that destroy sugar cane plants. By 2005, there were an estimated 100,000,000 cane toads in Australia. An exponential function that models the number of female cane toads in Australia t years after 1935 is given by f(t)=50(1.23)t .

a. Write a linear function p that models the number of cane toads in Australia t years after 1935. p(t)=_____
b. Describe the parameters in the exponential function, , in terms of the context of the problem. ____
c. Describe the parameters in the linear function, p , in terms of the context of the problem. ____
Question 4 d. Which model do you think is more appropriate to model the female cane toad population? Use the parameters of the functions to justify your reasoning. Linear or exponential?
Predict the population of female cane toads in Australia in 2000 based on each function. The linear function predicts that there would be ___ female cane toads in 2000. The exponential function predicts that there would be ___ female cane toads in 2000.

Answers

The linear function predicts that there would be 92857146 female cane toads in 2000 while the exponential function predicts that there would be 34898137 female cane toads in 2000.

Part A: The linear model of the number of cane toads

From the question, we have the following points

(t, f(t)) = (0,50) and (70, 100000000)

The linear function is then calculated as:

f(t) = [f(t2) - f(t1)]/[t2 - t1](t - t1) + f(t1)

This gives

f(t) = [100000000 - 50]/[70 - 0](t - 0) + 50

Evaluate

f(t) = 1428570.71t + 50

Hence, the linear function is f(t) = 1428570.71t + 50

Part B: The parameters in the exponential function

The exponential function is given as:

f(t) = 50(1.23)^t

So, the parameters are:

50 represents the initial value1.23 represents the ratet represents the number of years from 1935f(t) represents the number of cane toad in year t

Part C: The parameters in the linear function

The exponential function is calculated as:

f(t) = 1428570.71t + 50

So, the parameters are:

50 represents the initial value1428570.71 represents the ratet represents the number of years from 1935f(t) represents the number of cane toad in year t

Part D: The appropriate model

When the population of an entity is being model, it is best to use the exponential model, because the populations would grow exponentially for some time, and then stop growing at some point

Hence, the more appropriate model is the exponential model.

Part E: The number of female cane toads in 2000

The year 2000 is 65 years from 1935.

So, we have:

t = 65

For the exponential model, we have:

f(t) = 50(1.23)^t

The equation becomes

f(65) = 50(1.23)^65

Evaluate

f(65) = 34898137

For the linear function, we have:

f(t) = 1428570.71t + 50

The equation becomes

f(65) = 1428570.71 * 65 + 50

Evaluate

f(65) = 92857146

This means that. there would be 34898137 female cane toads in 2000 according to the exponential function.
