This question is incomplete. Hereis the complete question:

Which of the following options have the same value as 65% of 20 ?

(A) 0.65⋅20 (B) 65/100 divided by 20 (C) 65/20 * 100 (D) 65 * 20

Answer:

The correct answer is option (A) 0.65⋅20

Step-by-step explanation:

In this case they are asking us for an expression that is equivalent to 65% of 20. They are not asking us what is the value of that operation.

When we do a percentage calculation we can do it in two ways.

Let's see each one of them:

. (65 * 20): 100 =

1300: 100 = 13

. 0.65. 20 = 13

As we can see both ways we get the same result.

Given this information we can say that the correct answer is option A.

Find the sum of the first 63 terms of –19, -13, -7 …

boyakko [2]

The Given Sequence is an Arithmetic Sequence with First term = -19

⇒ a = -19

Second term is -13

We know that Common difference is Difference of second term and first term.

⇒ Common Difference (d) = -13 + 19 = 6

We know that Sum of n terms is given by : $S_n = \frac{n}{2}(2a + (n - 1)d)$

Given n = 63 and we found a = -19 and d = 6

$\implies S_6_3 = \frac{63}{2}(2(-19) + (63 - 1)6)$

$\implies S_6_3 = \frac{63}{2}(-38 + (62)6)$

$\implies S_6_3 = \frac{63}{2}(-38 + 372)$

$\implies S_6_3 = \frac{63}{2}(334)$

$\implies S_6_3 = {63}(167) = 10521$

The Sum of First 63 terms is 10521

Greg has decreased his running time by 1/10 minute each of the last six weeks. Write an expression to represent the total change

Nastasia [14]

x is your starting running time. 1/10 of a minute is 6 seconds, so you can do x - 6(6). 6 times 6 = 36, so your answer is x - 36 seconds. 36 seconds.

Answer Please???? Finn is baking cakes for a party. The number of cups of sugar Finn needs is proportional to the number of cake

Natali [406]

Answer:

Hello there!

The answer to your question is :

C: Finn needs 6 cups of sugar for 4 cakes.

D: Finn needs 1 1/2 cups of sugar for 1 cake.

Step-by-step explanation:

The graph clearly shows ( sides cups of sugar) (bottom number of cakes)

For sugar you need 6 cups to make 4 cakes

For sugar on the second question you need 1 1/2 cups of sugar to make 1 cake

Multiply 1 1/2 times 6 then divide and your answer is 4. That's 4 cakes out of 6 cups of sugar out of the original cups of sugar ( 1 1/2)

This is the confirmed answer I took the quiz and got 100%

Hopes this helps you!
