Find x.
A. 6/6
B. 24v3
C. 18
D.912

Answer:

36 m

Step-by-step explanation:

The area (A) of a square is calculated as

A = s² ( s is the side length )

Here A = 81 , then

s² = 81 ( take the square root of both sides )

s = [tex]\sqrt{81}[/tex] = 9

Perimeter = 4s = 4 × 9 = 36 m

Answer:

Step-by-step explanation:

Notice that both sides involve 7a - 2a, and both involve 4.  By the associative property the order in which the addends appear is immaterial; the left side therefore equals the right side.

Answer:

7a + 4 - 2a = 7a - 2a + 4

5a + 4 = 5a + 4

Step-by-step explanation:

7a + 4 - 2a = 7a - 2a + 4

​7a + 4 - 2a

Rearrange the terms.

7a - 2a + 4

Combine like terms.

5a + 4

The left side simplifies to 5a + 4.

7a - 2a + 4

5a + 4

The right side also simplifies to 5a + 4.

Answer:

[tex]m || n \\ (4x - 11) + (5x + 20) = 180 \\ 9x + 9 = 180 \\ 9(x + 1) = 180 \\ x + 1 = 20 \\ x = 19 \\ \\ then \\ (4x - 11) = (2y + 19) \\ (4 \times 19 - 11) = (2y + 19) \\ 65 = 2y + 19 \\ 2y = 46 \\ y = 23[/tex]

Answer:

6

Step-by-step explanation:

Answer:

Less than 14.

Step-by-step explanation:

Since we are multiplying 14 by 3/7, and 3/7 < 1, then 14 must be less than 14, because we're multiplying it by a fraction. Therefore, when we multiply by 3/7, we are essentially turning 14 into 3 parts out of 7 parts out of 14, or 6.

Answer:

-17 9/26 - > -17.35 , -17.3 with the mark over  ,- [tex]\sqrt{300}[/tex]   , 172/10

Step-by-step explanation:

Convert all of these into decimals

- [tex]\sqrt{300}[/tex]  -> -17.32

-17 9/26 - > -17.35

172/10 -> 17.2

-17.3 with the mark over 3 is  ->- 17.3333

Now arrange

-17 9/26 - > -17.35 , -17.3 with the mark over  ,- [tex]\sqrt{300}[/tex]   , 172/10

Answer: 50.8

Step-by-step explanation:

Answer:

A, [tex]\frac{5\sqrt{74}}{74}[/tex]

Step-by-step explanation:

Cosine of an angle is equal to the adjacent side of that angle over the hypotenuse of the triangle. Since the adjacent side is 5, and the hypotenuse is √74, the value is 5 / √74.

However, we can't have radicals (square roots) in the denominator, so we multiply the top and bottom by √74 so that the radical goes on the top.

Answer:

[tex]2x + 5y = 6z[/tex]

The slope of the graph of 2x + 5y = 6 is; -2/5.

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.

The slope of the line y = mx + c is calculated as follows:

m = Δy/Δx

To find the slope of the line of 2x + 5y = 6

Therefore, the slope of the line is;

2x + 5y = 6

5y = 5 - 2x

Now divide by 5

y = 1 - 2/5x

When we simplify it, then we get;

m = -2/5

Hence, the slope of the graph of 2x + 5y = 6 is; -2/5.

Answer:16 , 22

Step-by-step explanation:

Given

Chris is six-year older than his sister

The sum of their ages is 38

Suppose the age of Chris sister is x

So Chris age is [tex]x+6[/tex]

the sum is

[tex]\Rightarrow x+x+6=38\\\Rightarrow 2x+6=38\\\Rightarrow 2x=32\\\Rightarrow x=16[/tex]

Chris age [tex]16+6=22\ \text{years}[/tex]

Chris sister  Kennedy's age [tex]16\ \text{years}[/tex]

Answer:

C, or the y-intercept is (0, 70,000).

Step-by-step explanation:

The population is 20,000 from the start, so x is 0. The y-intercept is the y-value when the x is 0.

Answer:

x= 2[tex]\sqrt{6}[/tex]

Step-by-step explanation:

To solve this problem we first observe the Pythagoras equation. If a=x and b = 7 are the lengths of the legs of a right triangle and c= [tex]\sqrt{73}[/tex] is the length of the hypotenuse, then the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.

This relationship is represented by the formula:

a*a + b*b = c*c

[tex]x^{2}[/tex] + [tex]7^{2}[/tex] = [tex](\sqrt{73} )^2[/tex]

=> x= [tex]2\sqrt{6}[/tex]

Solution given.

Answer:

B

Step-by-step explanation:

The standard form of a circle equation is:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center and r is the radius.

We can plug in the given values to get:

(x - 1)^2 + (y - 2)^2 = 3^2

This is the sam as option B

Answer:

Water is leaving at 17500m^3 per minute

Step-by-step explanation:

Given

[tex]V(t)= 250(1600 - 80t + t^2)[/tex]

Required

The rate when time is 5 minutes

We have:

[tex]V(t)= 250(1600 - 80t + t^2)[/tex]

Open bracket

[tex]V(t)= 400000 - 20000t + 250t^2[/tex]

Differentiate

[tex]V'(t) = 0 - 20000 + 2*250t[/tex]

[tex]V'(t) = 0 - 20000 + 500t[/tex]

[tex]V'(t) = -20000 + 500t[/tex]

At 5 minutes, we have:

[tex]V'(5) = -20000 + 500*5[/tex]

[tex]V'(5) = -20000 + 2500[/tex]

[tex]V'(5) = -17500[/tex]

This means that water is leaving at 17500m^3 per minute

Answer:

y = 5√3

x = 10√3

Step-by-step explanation:

From the given sides

Adjacent = 15

Opposite = y

Hypotenuse = x

Angle of depression = 30degree

Using the SOH CAH TOA identity

tan theta = opp/adj

tan 30 = y/15

y = 15tan30

y = 15(1/√3)

y = 15√3/3

y = 5√3

Similarly

cos theta = adj/hyp

cos 30 = 15/x

x = 15/cos30

x = 15 /√3/2

x = 30/√3

x = 30√3/3

x = 10√3
