A pack of 8 batteries costs £4.99
How much does each battery cost?
Give your answer to the nearest penny.​

Answers

Answer 1
A). 50 penny
B) This type of battery is cost effective.
Step-by-step explanation:
A) A pack of 8 batteries cost 3.99 pounds so one battery will cost = 3.99/8 = 0.499 pound
Since 1 pound = 100 penny
So 0.499 pound = 100×0.499 = 50 penny
B). A pack of 6 batteries of the same type costs 2.79 pounds
So one battery will cost = 2.79/6 = 0.465 pound or 47 penny
Now we say that type A batteries are costlier than B. Therefore B type batteries are of a better value.
Answer 2
4.99/8 = £0.62375
rounded = £0.62
1 battery costs £0.62

Use the figure and given angle to find the measure of each angle below (tell me how many degrees it is).

Answers

9514 1404 393

Answer:

  ∠6 = ∠4 = 84°

  ∠5 = ∠3 = 96°

Step-by-step explanation:

Angle 4 and the marked angle (84°) are corresponding angles, so are congruent. Angles 4 and 6 are vertical angles, so are congruent.

  ∠6 = ∠4 = 84°

Angle 3 and the marked angle are a linear pair, so angle 3 is the supplement of 84°:

  ∠3 = 180° -84° = 96°

Angle 3 and angle 5 are alternate interior angles, so are congruent.

  ∠5 = ∠3 = 96°

Vrite and simplify an expression to find he total cost of x pencils , 1 poster board , and (x + 1) notebooks.

Answers

Answer:

The expression to find the total cost of x pencils, 1 poster board, and (x + 1) notebooks will be:

[tex]C=xp+b+nx+n[/tex]

Step-by-step explanation:

Consider '[tex]x[/tex]' be the number of pencils which were bought

Consider '[tex]p[/tex]'  denotes the cost of [tex]1[/tex] pencil

Consider '[tex]b[/tex]'  denotes the cost of [tex]1[/tex] poster board

Consider '[tex]x+1[/tex]' be the number of notbooks which were bought

Consider '[tex]n[/tex]'  denotes the cost of [tex]1[/tex] notebook

As we have to find the total cost. Let 'C' denotes the total cost

so the expression becomes

[tex]C=xp+b+\left(x+1\right)n[/tex]

simplifying

[tex]C=xp+b+nx+n[/tex]

Therefore, the expression to find the total cost of x pencils, 1 poster board, and (x + 1) notebooks will be:

[tex]C=xp+b+nx+n[/tex]

Step-by-step explanation:

If you subsitute x in "2x" you get 34. If you subsitute x for "4x - 4" you get 64.

After subtracting 180 from 98 you get 82. Add up 34, 64, and 82 then you get 180.

What is Probability?

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.

Given:

Total marbles = 10

Blue marbles=2

Number of times= 40

So, the number of times would you expect to draw a blue marble

=2/10 *40

=80/10

=8

Hence, 8 times would you expect to draw a blue marble.

Who climbs at a faster rate? Make sure to explain your answer and how you know

Answers

Answer:

Start at -150, then add 3(-5), then add 122.2. -150 + 3(-5) + 122.2 = -45.3.

The answer is -45.3 feet depth. while minus sign shows the descend under the water with water surface as starting point.

Step-by-step explanation:

Initial depth of diver under the water =-150feet=−150feet

Diver descends 5 feet per minute for 3.5 minutes =3.5*(-5)=3.5∗(−5)

                                                                                =-17.5=−17.5

Note: minus sign shows that the diver is under the water.

Diver ascends =122.2feet=122.2feet

Now adding all the terms a below as a numerical expression.

Current Depth of Diver after he descends 5 feet for 3.5 minutes and ascend 122.2 feet after  =-150-17.5+122.2=−150−17.5+122.2

                           =45.3feet=45.3feet

By taking the initial depth of diver from which we add or subtract the changes made when he ascends or descends in the water to get the current depth.

What number belongs in the leftmost empty cell?


What number belongs in the rightmost cell?

Answers

Answer:

leftmost empty cell: ⅓

rightmost empty cell: 3

Step-by-step explanation:

✔️If 2 pounds grapes cost $6, then x pounds of grapes cost $1.

Thus;

2 : 6 = x : 1

2/6 = x/1

Multiply both sides by

²/6 × 1 = x/1 × 1

²/6 = x

¹/3 = x

x = ⅓

✔️If 2 pounds grapes cost $6, then 1 pound of grapes cost $x.

Thus;

2 : 6 = 1 : x

²/6 = ¹/x

Cross multiply

2x = 6

Divide both sides by 2

2x/2 = ⁶/2

x = 3
