Kate and Nora each have a sum of money. The ratio of the amount of money Kate has to that of Nora is 3 : 5. After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9. Find the sum of money Kate had initially.

Answer:

Linda, Julie, Jenna, Karl

Step-by-step explanation:

Here, we want to list the students in order from lowest to highest

The key here is to have the scores in the same form, let us say decimals for ease of comparison

Jenna: 85% = 85/100 = 0.85

Linda’s= 32/40 = 80% = 0.8

Karl = 7/8 = 0.875

Julie = 0.83

So from lowest to highest, we have;

Linda, Julie, Jenna, Karl

Answer:

16

Step-by-step explanation:

To find 80% of 20, multiply .80 x 20

.80×20 = 16

This is how you multiply percentages--put the decimal point 2 places to the left, then multiply.  In this case, you're looking at 80%, so move the decimal point two places to the left

80.0 becomes .80

Then multiply that by the number you're trying to find the percentage of

Answer:

Area of rectangular garden = lxb = 10*5

                                             = 50 sq. inch

when area increases by six times

new area = 50*6 = 300 sq inches

now,

let x be increasement in both  length and width

(5+x) (10+x) = 300

50 + 5x + 10x + x² = 300

x² + 15x - 250 = 0

x²+ 25x-10x -250 = 0

x(x+25) - 10 (x+25) = 0

( x-10) (x+25) = 0

either x + 25 =0

x = -25 length can be negative

0r x-10 = 0

x = 10

so 10 inches is increase on both side

Answer:

$2,430

Step-by-step explanation:

Scale of the drawing = ⅓ in. to 1 ft

Measurement of the bathroom on paper = 3 in. by 3⅓ in.

Actual measurement of the bathroom:

3*3 = 9 ft

3⅓ * 3 = 10 ft

Area of the bathroom = 9*10 = 90 ft²

Let's find how many square tiles would cover 90 ft².

The side length of 1 tile is said to be ⅓ ft.

Therefore, the area of 1 tile would be ⅓*⅓ = ⅑ ft².

Number of tiles that would cover 90 ft² would be:

90/⅑ = 90*9

= 810 tiles

If 1 tile cost $3.00, therefore 810 tiles would cost:

810 * 3 = $2,430.

Answer:

xy+5

Step-by-step explanation:

Answer: xy + 5

Work: So, we are going to divide everything by two. So, in the current equation, it divides everything by two, including the current two, which cancels it. So, after all the division, we get the current answer; xy + 5

I hope this helps, and Happy Holidays! :)

Answer: 6 (z+13)

Step-by-step explanation:

Answer:

Step-by-step explanation:

10-z=6

We move all terms to the left:

10-z-(6)=0

We add all the numbers together, and all the variables

-1z+4=0

We move all terms containing z to the left, all other terms to the right

-z=-4

z=-4/-1

z=+4

Answer:

9.1 = a+4

Step-by-step explanation:

The right side has two different values, variable a, constant 4.

The left side has the constant 9.1.

If both sides are equal, then

a + 4 should equal 9.1

Answer:

9.1 = a+4

Answer:

Grant's weekly allowance is $20.

Step-by-step explanation:

We know that Grant ended with $15. We can say that Grant's weekly allowance is x.

x/2 + 5 = 15

Now to solve:

x/2 + 5 - 5 = 15 - 5 (subtract 5 from both sides to isolate the x/2)

x/2 = 10

x/2 * 2 = 10 * 2 (multiply both sides by 2 to isolate the x)

x = 20

Grant's weekly allowance is $20.

Answer:

x = 35

Step-by-step explanation:

we know that all triangles add up to 180

you first need to make an expression in which the angles equal 180

105 + 140 + x = 180

         145 + x = 180

subtract 145 from both sides

                  x = 35

Answer:

32.64 < 3.264

7.489 < 7.498

0.350 > 0.305

9.164  <  9.614

Step-by-step explanation:

The first digit to the right of decimal point is in the tenths place. The second digit to the right of decimal point is in the hundredths place. The third digit to the right of decimal point is in the thousandths place. The fourth digit to the right of decimal point is in the ten thousandths place and so on.
