B. Ronit has 32 bananas. She started with 12 bananas. She bought 4 bunches of the same number (x) . How many bananas were in each bunch?

Step-by-step explanation:

This one is right because if you were to actually solve this problem the equation would be the exact same

She has 32 bananas (=32)

She started with 12 (12+)

and she bought 4 more bunches, but we don't know how many are in each bunch, which would be X

12+4x =32

What is the measure of angle x?

Answers

Answer:

x = 60°

Step-by-step explanation:

We know that ∠H is 30° and we know that ∠J is 90° thanks to the red box. The sum of the angles of a triangle is 180°, so we can use this to solve for x.

x + 30 + 90 = 180

x + 120 = 180

x = 60

Therefore, it is 60°.

Now the population of bacteria is two to the fourth power times two to the sixth power. Expressed as a power, how many bacteria is on the petri dish after 150 minutes?

Answers

Answer: 2¹⁰ bacteria

Step-by-step explanation:

There were originally 2⁴ bacteria in the dish.

After 150 minutes this number doubled 6 times which means it increased by 2⁶.

The number of bacteria will become:

= 2⁴ * 2⁶

= 2⁴⁺⁶

= 2¹⁰ bacteria

Answers:

(a) Yes this sequence is arithmetic.(b) The common difference is d = -3

=================================================

Explanation:

This sequence is arithmetic because we're adding -3 to each term. This is the same as subtracting 3 from each term.

-13 + (-3) = -13 - 3 = -16

-16 + (-3) = -16 - 3 = -19

-19 + (-3) = -19 - 3 = -22

and so on. The term we add on each time is the common difference. It describes how the terms are spaced out, and how to generate each new term. The negative common difference is due to the sequence terms decreasing. An arithmetic sequence and a linear function are closely related ideas.

What is the volume of the following triangular pyramid?

Answers

Answer:

The volume of the triangular  pyramid

         V = 566.66 in³

Step-by-step explanation:

Step(i):-

The volume of the triangular  pyramid

            [tex]= \frac{1}{3} X base area X height[/tex]

Base area  = Area of the triangle

             [tex]A= \frac{1}{2} X base X height[/tex]

 Given the base of the triangle  (b) = 17in

  Given Height of the triangle (h ) =10 in

    [tex]A= \frac{1}{2}( 17 ) (10) = 85[/tex]

The base area of the pyramid ( A) = 85 in²

Step(ii):-

Given the height of the pyramid  (h) = 20in

The volume of the triangular  pyramid

            [tex]= \frac{1}{3} X base area X height[/tex]

The volume of the triangular  pyramid

         = [tex]= \frac{1}{3}( 85)(20) = 566.66[/tex]

Final answer:-

The volume of the triangular  pyramid

         V = 566.66 in³

v + f - e = 2

Step 2: Solve for e

Subtract v on both sides:                    f - e = 2 - vSubtract f on both sides:                     -e = 2 - v - fDivide -1 on both sides:                       e = -2 + v + f

An economy package of cups has 960 green cups. If the green cups are 40% of the total package, how many cups are in the package?

Answers

Answer: 2400 cups

Step-by-step explanation:

total # of cups = x

# of green cups = 960

% of green cups of total = 40%

# green cups/# of total cups = % of green cups/% of total cups

960/x = 4/10

9600 = 4x

2400 = x
