236462700.806 to the nearest cent

Answers

Answer:

236462700.81

Step-by-step explanation:

The nearest cent refers to the hundreds place, because 100 pennies (or cents) make 1 dollar. We look at the number to the right of the hundredths place and if it is less than 5 we round down, but if it is 5 or more we round up. Since 6 is more than five we round up, and are left with 236462700.81.

There are 312 calories in six ounces of a certain ice cream. How many calories are there in three pounds?

Answers

1 lb = 16 oz
312/6 = 52 cal/oz
16(3) = 48 oz
52(48) = 2496 calories

Answer:

2496 calorise

Step-by-step explanation:

3 pounds = 3 x 16 = 48 ounces

312 cal = 6 ounces, so the unit rate is ( 312 ÷ 6 = 52) 52 cal per ounce

52 x 48 ounces = 2,496

Winnie needs to spend $120 on two kinds of fancy cakes:
Chocolate Delight and Coffee Comfort. The Chocolate cake
sells at 12 dollars per slice and the Coffee cake sells at 10
dollars per slice.
If Winnie buys 5 slices of Chocolate cake, how many slices of
Coffee cake does she buy?
___slices

Answers

Answer:

Winnie needs to buy 6 slices of Coffee cake.

Step-by-step explanation:

12 * 5= $60 (chocolate cake)

120 - 60= 60

since we know the coffee cake costs $10(per slice) we do:

60/ $10= 6 slices of coffee cake.

How do you know whether an ecuation is an identity? How many solutions does an identity have? Explain

Choose the correct answer below

O, A. An equation is an identity w it can be rewitten as an equation of the form"variable = ruumiker, such as x=5 or y=3. Such an equation has an infinite

number of solutions because a variable can be any number

OB. An equation is an idersity it can be rewritten as an equation of the form "variable = number," such as x=5 or y=3. Such an equation has only one solution,

and the solution is called the identity of the variable

OC. An equation is an identity #it can be rewritten as 0-0. Such an equation has only one solution, 0, and that is the identity of the variable

OD. An equation is an identity if it can be rewritten as 0 =0. Such an equation has an infinite number of solutions because it reduces to a true statement

regardless of the value of the variable

Answers

Answer: D. An equation is an identity if it can be rewritten as 0 =0. Such an equation has an infinite number of solutions because it reduces to a true statement regardless of the value of the variable.

Step-by-step explanation:

For an identity equation ; The value on the right and left hand side of the equation are equal :

Left hand side = Right hand side

The solution to an identity solution is infinite because the equation holds true for every value substituted for the variable.

Hence, for every value substituted in for the variable in the equation, the equation is a true statement.

Anita guessed that there were 180 pieces of candy in a jar, they were actually 220 pieces of candy in the jar what was Anita's approximate percent error

Answers

Answer:

18%

Step-by-step explanation:

Solve by making 180/220 into a percentage:

First, simplify the fraction by both parts by 20. This will result in the fraction 9/11.

To make it a percentage, write it as a ratio:

9/11 = x/100

Multiply both sides by 100 and 11:

11x = 900

Divide both sides by 11:

x = 81.818181...

Subtract from 100 to find the error:

18.181818...

So about 18%

Answers

Answer:

x = 12

Step-by-step explanation:

Solve for x:

[tex] \longrightarrow [/tex] 5 (x - 6) = 2(x + 3)

Expand out terms of the left hand side:

[tex] \longrightarrow [/tex] 5x - 30 = 2(x + 3)

Expand out terms of the right hand side:

[tex] \longrightarrow [/tex] 5x - 30 = 2x + 6

Subtract 2x from both sides:

[tex] \longrightarrow [/tex] (5x - 2x) - 30 = (2x - 2x) + 6

5x - 2x = 3x:

[tex] \longrightarrow [/tex] 3x - 30 = (2x - 2x) + 6

2x - 2x = 0:

[tex] \longrightarrow [/tex] 3x - 30 = 6

Add 30 to both sides:

[tex] \longrightarrow [/tex] 3x + (30 - 30) = 30 + 6

30 - 30 = 0:

[tex] \longrightarrow [/tex] 3x = 6 + 30

6 + 30 = 36:

[tex] \longrightarrow [/tex] 3x = 36

Divide both sides of 3x = 36 by 3:

[tex] \longrightarrow [/tex] [tex] \sf \dfrac{3}{3}x = \dfrac{36}{3} [/tex]

[tex] \sf \dfrac{3}{3} = 1: [/tex]

[tex] \longrightarrow [/tex] [tex] \sf x = \dfrac{36}{3} [/tex]

[tex] \sf \dfrac{36}{3} = 12: [/tex]
