1/20 written as a decimal

Answers

divide 1 by 20.
1÷20= 0.05
so 1/20 written as a decimal is 0.05

First multiply the top and bottom of the fraction by 5 so it is out of 100.
Now that you have 5/100 you can easily change the numerator into a decimal

What are the solutions of 3(x – 4)(2x - 3) = 0? Check all that apply.

Answers

Answer:

x=4 x = 3/2

Step-by-step explanation:

3(x – 4)(2x - 3) = 0

We can use the zero product property

x-4 =0 2x-3=0

Solve each equation

x-4 =0 2x-3=0

x=4 2x=3

x =3/2

Jack bought a pizza and a drink for $2.65. if the pizza costs a penny more than 3 times the cost of the drink, how much did each cost?

Answers

To get the answer we can prepare equation. Lets assume x its drink.
Finally we get the equation
3x+x+0.01=2.65
4x+0.01=2.65 /-0.01
4x=2.64 /:4
x=0.66 - cost of drink
3x+1 ---- 3*0.66+0.01=1.99 - cost of pizza

66 cents for drink. and 1.99 for the pizza. hope thus helped

Sandra writes (4 times 30)+(4 times 2) and says the quotient for 128 divided by 4 is 8. is she correct? Explain

Answers

Sandra's statement is incorrect because she equated the expression (4 times 30) + (4 times 2) with the quotient of 128 divided by 4, which are two different values.

We have,

No, Sandra is notcorrect in her statement.

Let's break down the given expression and evaluate the quotient separately.

First, let's simplify the expression (4 times 30) + (4 times 2):

(4 x 30) + (4 x 2) = 120 + 8 = 128

Now, let's evaluate the quotient for 128 divided by 4:

128 divided by 4 = 32

So, the correctquotient for 128 divided by 4 is 32, not 8.

Thus,

Sandra's statement is incorrect because she equated the expression (4 times 30) + (4 times 2) with the quotient of 128 divided by 4, which are two different values.
