Explain how you know 21 over 30 is greater than 2 over 3

1 answer:

4 0

<span>So we need to explain how we know 21/30 is greater than 2/3. Well lets expand 2/3 by multiplying the numerator and the denumerator by 10. That way we get 20 / 30. Since 21/30 has 1/30 more than 20/30 we can clearly see that 21/30 is greater than 20/30 or 2/3.</span>

Nathan has $40 in a savings account. The interest rate is 5% per year and is not

fgiga [73]

Money with Nathan in his savings account = $40

Rate of interest per annum = 5%

We know that :

$\color{hotpink}\tt \: simple \: interest \color{plum}= \frac{principal \times rate \times time}{100}$

In this case :

Principal = $40

Rate = 5%

Time = 1 year

Simple interest he will earn in 1 year :

$=\tt \frac{40 \times 5 \times 1}{100}$

$= \tt \frac{200}{100}$

$\color{plum} =\tt\$ \: 2$

Amount = Principal + Interest

Amount Nathan has to pay at the end of one year :

$= \tt40 + 2$

$\color{plum} =\tt \$42$

Thus, at the end of 1 year Nathan has to pay $42.

Therefore, simple interest Nathan will earn in 1 year = $2

All of the coats in a clothing store were on sale for 30% off the original price. Carlotta paid $41.30 for a coat after the disc

Yakvenalex [24]

(original price) -0.30*(original price) = $41.30
(original price)*0.7 = $41.30
(original price) = $41.30/0.70 = $59.00

The coat's original price was $59.00.

Which is the graph of y = 5log(x+3)

Maurinko [17]

Answer:

We are given a equation as:

5log(x+3)=5

We are asked to find a graph that is used to solve the above equation.

We can write the given equation as:

we will divide both side of the equation by 5 to obtain:

log(x+3)=1

Now we have to determine which graph represents the function:

y=log(x+3)

since we know that when x=-2.

y=log(-2+3)=log(1)=0

Hence, the graph should pass through (-2,0).

Hence, the graph that satisfies this is attached to the answer.
