If 25% of a number is 40, what is the missing number?

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

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

It's an inverse operation thing.

Answer: See explanation

Step-by-step explanation:

From the question, we are told to prove that prove d + (8d + 1) + 7 is equivalent to 8 + 9d.

= d + (8d + 1) + 7

First we need to open the bracket. This will be:

= d + (8d + 1) + 7

= d + 8d + 1 + 7

Collect like terms

= 9d + 8

= 8 + 9d

Therefore, we have proven that + (8d + 1) + 7 is equivalent to 8 + 9d.

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

Answer:

The greatest number of flowers that could be in a bouquet is 9 flowers.

Each bouquet would contain: 3 roses, 1 daise and 5 tulips

Step-by-step explanation:

Sandy has 27 roses, 9 daisies, and 45 tulips. She wants to arrange all the flowers in bouquets. Each bouquet has the same number of flowers and the same type of flower. What is the greatest number of flowers that could be in a bouquet?

We solve the above question using Greatest Common Factor method.

We find the factors of 27, 9 and 45

The greatest common factor is the highest factor common to these 3 number

Hence:

The factors of 9 are: 1, 3, 9

The factors of 27 are: 1, 3, 9, 27

The factors of 45 are: 1, 3, 5, 9, 15, 45

Then the greatest common factor is 9.

Therefore, the greatest number of flowers that could be in a bouquet is 9 flowers

Each bouquet would contain

For 27 roses = 27/9 bouquet = 3 roses

For 9 daisies = 9 daisies/9 bouquet = 1 daisies

For 45 tulips = 45 tulips/9 bouquet = 5 tulips

Answer:

y= 48 + 0.1x

x= miles driven

Step-by-step explanation:

We need to calculate the fixed and variable cost (per mile) of renting a car. To do that, we will use the high-low method:

Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)

Variable cost per unit= (65 - 58) / (170 - 100)

Variable cost per unit= $0.1 per mile

Fixed costs= Highest activity cost - (Variable cost per unit * HAU)

Fixed costs= 65 - (0.1*170)

Fixed costs= $48

Fixed costs= LAC - (Variable cost per unit* LAU)

Fixed costs= 58 - (0.1*100)

Fixed costs= $48

y= 48 + 0.1x

x= miles driven

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:

The length of YZ is 22.30mm.

Step-by-step explanation:

Basically we need to find the hypotenuse of the triangle, or the longest side.

The formula for finding the hypotenuse of a triangle is: c = √(a² + b²)

First we need to multiply 14.3 and 17.1 to the second power.

14.30 × 14.30 = 204.49

17.10 × 17.10 = 292.41

Now we add our two sums.

204.49 + 292.41 = 496.90

Now we need to find the square root of 496.90, which is 22.2912539.

Rounded to the nearest DP(Decimal point), it's 22.30
