Step-by-step explanation:

Answer:  LADB = 29

Step-by-step explanation:

The steps arranged in the correct order is Add 4 to both sides, Divide both sides of the equation by 3, Take the log of each side, Divide each side by log 2, Add 5 to each side of the equation and Use the Exponential Property and write in decimal form.

An equation is an expression that shows the relationship between two or more numbers and variables.

Given the equation 3(2 ^ (2t - 5)) - 4 = 10

Add 4 to both sides:

3(2 ^ (2t - 5)) - 4 + 4 = 10 + 4

3(2 ^ (2t - 5)) = 14

Divide both sides of the equation by 3:

[3(2 ^ (2t - 5))] / 3 = 14/3

2 ^ (2t - 5) = 14/3

Take the log of each side:

(2t - 5)log(2) = log(14/3)

Divide each side by log 2:

2t - 5 = log(14/3) / log(2)

Add 5 to each side of the equation:

2t = log(14/3) / log(2)

Use the Exponential Property and write in decimal form:

t = 1.11

The steps arranged in the correct order is Add 4 to both sides, Divide both sides of the equation by 3, Take the log of each side, Divide each side by log 2, Add 5 to each side of the equation and Use the Exponential Property and write in decimal form.

Answer:

see explanation

Step-by-step explanation:

using the identity

sin²x + cos²x = 1

consider left side

(cosA - sinA)²

= (cosA - sinA)(cosA - sinA) ← expand using FOIL

= cos²A - sinAcosA - sinAcosA + sin²A

= cos²A + sin²A - 2sinAcosA

= 1 - 2sinAcosA

What is circumference?

The circumference of the circle is the length of the curve traced out from the fixed point which is equidistant from the locus of the curve.

Given that:-

The circumference of the circular swimming pool will be:-

C  =  2 π r

C  =  2  x  π  x  7

C   =  44 ft

Therefore the distance she has walked around a swimming pool is 44 ft.

The equation for the number of arrangement from the number of guest is y = 12x + 2

The pattern is given as:

x     y

0     2

1     14

2    26

3     38

The above table represents a linear function;

Start by calculating the slope (m) using:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{14 - 2}{1 - 0}[/tex]

Evaluate

m = 12

The equation is then calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

So, we have:

y = 12(x - 0) + 2

Evaluate

y = 12x + 2

Hence, the equation for the number of arrangement from the number of guest is y = 12x + 2

The answer will be A number line going from 27 to 37. An open circle is at 32. Everything to the right of the circle is shaded.

The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than’, or < ‘less than’.

We have an expression of inequality:-

(-1/2)p < -16

p > 32 . . . . . . multiply by -2; this reverses the inequality symbol

The open circle will be at 32; the line will be shaded for higher values (to the right).

Hence the answer will be A number line going from 27 to 37. An open circle is at 32. Everything to the right of the circle is shaded.

Answer: A

Step-by-step explanation:

The area of the square is 10^2 = 100.

The area of the circle is (pi)(5^2) = 25pi.

So, the area of the region in the square but not in the circle is 100 - 25pi.

Thus, the desired probability is (100-25pi)/100, which is about 21.5%

Mode is what number occurs the most in data or in this question which number contains the most X's

Answer:

3 is the mode of the data set shown

Step-by-step explanation:

What is shown in the picture is called a data set. What we need to find is the mode. The mode, is the number shown in the data the most. Each x shown represents how many times the number below it shows in the data set. So, all we need to do is find the column with the most x's.

Through doing this, we can see that the column of 3, has the most x's (4 x's). Meaning that 3 is the mode of the data.

b = 10

b = 17

Step-by-step explanation:

Hello!

Usually, when you want two different integer solutions, you probably want the quadratic to be factorable.

So what we want to know is that b should be the sum of the factors in 16.

Factors of 16: 1, 2, 4, 8, 16

Factor pairs:

Factor Sums:

These are our possible b-values.

Check:

Let's try 17 first:

Now 10:

And finally, 8:

Since x = 4 is a repetitive integer, we cannot use 8 as a value for b.

Answer:

Answer:

Therefore, June gets £6

Step-by-step explanation:

Total amount = £20

Assume:

June's share = a

Sushil's share = b

Fiona's share = c

a = 2b -----------------------(1)

b = 3c -----------------------(2)

c = b ÷ 3 -------------------(3)

a + b + c = £20  --------(4)

Substitute equations (1) and (3) in equation (4)

2b + b + (b ÷ 3) = £20

10b ÷ 3 = £20

b = £20 * 3 ÷ 10 = £6

a = 2 * £6 = £12

c = £6 ÷ 3 = £3

Therefore, June gets £6
