The length of a rectangle is 3x-4 and the width is x. The perimeter is 72 feet. What is the measure of the length?

Answers

Answer 1
Answer : The length is 26ft

First, you would have to set an equation to find the value of x. To find this equation you would multiply both expressions for length and width by two. You would get the expression (6x-8) for length and the expression (2x) for width. You would then add these and make them equal to the perimeter, 72. You would get the equation 8x-8=72. Solving this equation would give you x=10. You just plug this value of x into the expression for length, which gives you the answer 26 ft.

If the radius of a circle is 9 cm, what is the area of the circle?
The diameter of the circle is 100 cm what is the circumference of the circle? (Use = 3.14.)

Answers

Step-by-step explanation:

the formula for the area of a circle is

πr²

plug 9 in for r (radius) to get

3.14 (81) = 254.34 cm² as our area

the circumference is equal to πd , with π being pi and d being diameter.

the circumference is then 3.14(100) = 314cm

7p-5=6p+8 what is the answer to that

Answers

Answer:

p=13

Step-by-step explanation:

Answer:
P=13

Explanation:
First you move one of the p to combine with the other p. I choose the 6p to be the moving. Since 6p is a positive number, you subtract it when you move it. 7p-6p= 1p
Next you move the constants which are -5 and 8. Since we already move the ps to the left side, we should move the constants to the right side. Since -5 is a negative number, we need to add it when we move it. 5 + 8 =13
So p equals to 13

What is the equation of the line that passes through the point (1, 3) and is perpendicular to the line 2x+3y=15?

Answers

The equation of the line that passes through the point(1, 3) and is perpendicular to the line 2x + 3y = 15 is y = 3 / 2x + 3 / 2.

How to find the equation of a line perpendicular to another?

The line passing through (1, 3) is perpendicular to the equation 2x+3y=15.

Therefore,

y = mx + b

where

m = slopeb = y-intercept

Hence,

3y = -2x + 15

y = -2 / 3 x + 5

For line to be perpendicular it must follow the following rules;

m₁m₂ = -1

m₁(-2 / 3) = -1

-2m₁ = -3

m₁ = 3 / 2

Therefore, the equation can be found as follows:

3 = 3 / 2(1) + b

3 = 3 / 2 + b

b = 3 - 3 / 2

b = 6 - 3 / 2

b = 3 / 2

Hence,

y = 3 / 2x + 3 / 2

Solve the inequality. Graph the solution.
2n > 20

Pls show Yhur work

Answers

Answer:

n > 10 is the inequality solved, but there is no way to graph this equation.

Step-by-step explanation:

Key skills: Inequalities, Division

1) You are given the inequality 2n > 20

2) To solve for n, you have to divide by 2 on both sides.

3) 2n/2 > 20/2

4) 2n/2 = n

5) 20/2 = 10

6) The inequality is n> 10

There is no way to graph this as it has no x or y values in it (coordinate graphing requires x or y in the inequality)

The solution to the inequality is n > 10

To solve the inequality 2n > 20, we need to isolate n by dividing both sides of the inequality by 2:

2n/2 > 20/2

n > 10

The solution to the inequality is n > 10, indicating that n must be greater than 10 for the inequality to hold true.

To graph the solution, we represent the solution on a number line. We start by marking a point at 10, and then shade the region to the right of 10 to indicate all values greater than 10.

Graphically, it would be represented as an open circle at 10 with a shaded line extending to the right.

This represents the solution n > 10.

the area of a triangle is 30cmsquare find the base if the altitude exceeds the base by 7 cm​

Answers

Answer:

5 cm

Step-by-step explanation:

Area= 1/2 base×altitude

let base be x cm hence altitude = x+7 cm

30 = 1/2 (x) (x+7)

60= x^2 + 7x

x = 5 or - 12

but measurements can't be in negative form hence -12 is discarded. Thus x= 5 cm

x= base hence base = 5cm

Answer:

base = 5 cm

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the altitude )

let base be b then h = b + 7

Given A = 30, then

[tex]\frac{1}{2}[/tex]b(b + 7) = 30 ( multiply both sides by 2 to clear the fraction )

b(b + 7) = 60 ← distribute left side

b² + 7 = 60 ( subtract 60 from both sides )

b² + 7 - 60 = 0 ← in standard form

(b + 12)(b - 5) = 0 ← in factored form

Equate each factor to zero and solve for b

b + 12 = 0 ⇒ b = - 12

b - 5 = 0 ⇒ b = 5

However, b > 0, thus b = 5

That is the base is 5 cm

In a certain breed of cattle, the length of gestation has a mean of 284 days and a standard deviation is 5.5 days. One length of gestation had a z-score of -1.70. Which of the following sentences best interprets the z-score?
A. The length of this gestation period was longer than the mean length of gestation periods by 1.7 days.
B. The length of this gestation period was shorter than the mean like the gestation periods by 1.7 days.
C. The length of this gestation period was longer than the mean length of gestation periods by 1.7 standard deviations.
D. The length of this gestation period was shorter than the mean length of gestation periods by 1.7 standard deviations.

Answers

Answer:

The statement that best interprets the z-score is;

D. The length of the gestation period was shorter than the mean length of gestation period by 1.7 standard deviations

Step-by-step explanation:

The given parameters are;

The length of the gestation period of the cattle breed = 284 days

The standard deviation = 5.5 days

The z-score of one length of gestation period was z = -1.70

The formula for finding the z-score, z is presented as follows

[tex]Z=\dfrac{x-\mu }{\sigma }[/tex]

Where;

x = The observed value for the gestation period

μ = The sample mean length for the gestation period = 284

σ = The gestation period standard deviation = 5.5

When Z = -1.70, we have;

[tex]-1.70 =\dfrac{x-\mu }{\sigma }[/tex]

∴ x - μ = -1.7 × σ

∴ x is shorter than μ by 1.7×σ

Therefore, the length of the gestation period, x, was shorter than the mean length of gestation period, μ, by 1.7 standard deviations, σ.

Answer:

D. The length of the gestation period was shorter than the mean length of gestation period by 1.7 standard deviations

Use the graph shown. State the number of real zeros of the function.

Answers

Answer:

Option B

Step-by-step explanation:

Zeros of a function are defined by the values of x at y = 0,

In other words, x-intercepts of a function graph are the zeros of the function.

Real zeros means graph should intersect or touch the x-axis.

If it is imaginary, the graph will have no x-intercept.

From the graph attached,

There are 3 points where the graph intersects the x-axis.

Therefore, the function will have 3 real zeros.

Option B is the answer.
