Answer and Explanation:

To find : Explain why \frac{45}{100} is written as decimal with a 4 in the tenths place and a 5 in the hundredths place ?

Solution :

When we write fraction as decimal we place decimal according to number of zeros in the denominator.

As \frac{45}{100}=0.45

According to place value system,

Ones   |    Tenths        Hundredths

   0               4                    5

As first digit to the right of decimal point is basically tenths place and second digit to the right of decimal point is basically hundredths place.

So, When we write \frac{45}{100} in decimal form i.e. 0.45 then 4 in the tenths place and a 5 in the hundredths place.

What is the y-intercept of the line that is
DaniilM [7]

Answer:

The y-intercept of the line would be (C) 8

Step-by-step explanation:

The slope of the line with the equation y = -3x - 5 is -3. When figuring out a slope perpendicular to another line you would use the negative reciprocal of the slope which would lead to the slope of the line to be 1/3.

We know it passes through the point (-3,7), substituting x and y, we would then get our new equation, (7) = \frac{1}{3}( -3) + b.

Solve the equation by multiplying -3 with 1/3 and the product would be -1. Add negative one on both sides and you would get 8 = b.

Can anyone help me with the 7th and 8th question which I have taken a bad photo of?

<u>Question 7:

Define x :
</u>
Let the digit in the ones place be x.
The digit in the tens place is  x+2.

The sum of the digit and its reverse is 66

<u>Find x:</u>

10(x + 2) + x + 10x + (x + 2) = 66
10x  + 20 + x + 10x + x + 2 = 66
22x + 22 = 66
22x = 44
x = 2

<u>Find the number:</u>

The number in the ones place = x= 2
The number in the tens place = x = 2 + 2 = 4

Answer : The number is 42.

<u>Question 8:</u>

<u>Define x:</u>

Let the digit in the tens place be x.
The digit in the ones place is x+7.

The number  = 10x + x + 7 = 11x + 7

If the digit interchange,
the number = 10(x + 7) + x = 10x + 70 + x = 11x + 70

<u>Find x:
</u>
9(11x + 7) = 2(11x + 70)
99x + 63 = 22x + 140
99x - 22x = 140 - 63
77x = 77
x = 1

<u>Find the number:
</u>
x = 1
x + 7 = 1 + 7 = 8
So the number is 18

Answer: The number is 18.
