Step-by-step explanation:

r=3/2=(4.5)/3=3/2

it is geometric, so we will use this equation:

a(n)=a1*(r)^(n-1)

and we have a(1)=2 , r=3/2    

So  explicit formula:

a(n)=2*(3/2)^(n-1)

Answer:

The second option: 4 1/2 x = 22 1/2

Step-by-step explanation:

The whole volume is 22 1/2 so that is on one side of the equals sign but it must be by itself. Then the formula for volume is length x width x height.

so 22 1/2 = l x w x h

Two of these numbers are given. You multiply 3 x 1 1/2 to get 4 1/2 times the unknown value of x

Answer:

a)

[tex]a=23-z[/tex]

b)

First of all, I divided both sides by 2, simplified, and then subtracted z from both sides. Then, I got the final result for 'a'.

Step-by-step explanation:

a) Solving the equation

Given the expression

[tex]2\left(z+a\right)=46[/tex]

Divide both sides by 2

[tex]\frac{2\left(z+a\right)}{2}=\frac{46}{2}[/tex]

simplify

[tex]z+a=23[/tex]

subtract z from both sides

[tex]z+a-z=23-z[/tex]

[tex]a=23-z[/tex]

Thus, the value of a:

[tex]a=23-z[/tex]

b) Work Process

First of all, I divided both sides by 2, simplified, and then subtracted z from both sides. Then, I got the final result for 'a'.

Step-by-step explanation:

Answer:

There were 5 toppings on his pizza.

Step-by-step explanation:

From the information given, you can say that the total cost of the pizza would be equal to the cost of the 24-inch cheese pizza plus the result of multiplying the cost of each topping for the number of toppings, which can be expressed as:

c=17.50+2.35x, where:

c is the total cost

x is the number of toppings

Now, you can replace the total cost with $29.25 and solve for x:

29.25=17.50+2.35x

29.25-17.50=2.35x

11.75=2.35x

x=11.75/2.35

x=5

According to this, the answer is that there were 5 toppings on his pizza.

Answer:

$129

Step-by-step explanation:

First, we'll figure out how much Racquel earns per week by multiplying how much she gets per hour by the number of hours she works per week. We can solve 4x10.75 to find out how much money Racquel earns per week. We can solve that to find out that she earns $43 per week. Then, we can multiply that by 3 to find out how much she earns in 3 weeks. Once we solve 43x3 we will end up with an answer of $129 over the course of 3 weeks.

Step-by-step explanation:

Answer:

30 degrees

Step-by-step explanation:

Since a triangle's angle measures add up to 180, you need to set up an equation to find the missing side.

130+20+? = 180

150+?=180

180 minus 150 is 30 so the missing side is 30 degrees

Answer:

30 degrees

Step-by-step explanation:

All three angles in a triangle always add up to be 180 degrees.

Add 20 and 130 to get 150. Then, subtract 150 from 180 to get 30 degrees.

Answer:-8.75

Step-by-step explanation:

Answer:

C. -8.75

Step-by-step explanation:

Ultimately, you are dividing a negative number by a positive number which makes the answer negative.  The only way the answer can be positive if it's dividing by two negatives or two positives.  You can also assume that since the divider is greater than 1, it is usually less than the first number for this statement which makes your answer -8.75.

Answer:

  y = 5x +20

Step-by-step explanation:

We assume you want the total cost (y) of x months of membership at the dance club.

This will be the sum of the start-up fee (20) and the product of the monthly fee (5) and the number of months (x).

  y = 5x +20

Comparing this to the slope-intercept form of the equation of a line, we see ...

  y = mx + b

  m = 5

  b = 20

Answer:

(x, y) → (x + 8, y - 3)

Step-by-step explanation:

To find the rule of translation, we can find one point on both figures to calculate the change in the x-axis and y-axis.

Let's say we take the point D (0, -1).

(-1, 0) → (7, -3)

Change in x = 7-(-1)

                    = 7 + 1

                    = 8

Change in y = -3-0

                    = -3

Thus, the change is (x + 8, y - 3)

Answer:

6 * 42 = 6 * (20 + 22)

= (6 * 20) + (6 * 22) = 120 + 132 = 252

Step-by-step explanation:

Here, we want to multiply 6 by 42 using distributive property

In this case, we can have the distributive property as;

a * ( b + c) = ab + bc

Thus, we can represent 42 as (20 + 22)

so 6 * 42 becomes 6 * (20 + 22)

Using the distributive property, we have

(6 * 20) + (6 * 22)

= 120 + 132 = 252

Ounces of yogurt need for 10 ounces of blueberries is 8 ounce

Ratio of ounces of blueberries to ounces of yogurt = 4:5

Ounces of yogurt need for 10 ounces of blueberries

Ounces of yogurt need for 10 ounces of blueberries = 10[4 / 5]

Ounces of yogurt need for 10 ounces of blueberries = 2[4]

Ounces of yogurt need for 10 ounces of blueberries = 8 ounce

the 3rd angel is 120

the two exterior angels can be, 60 and 152
