16) A: decimal form

17) A: 0.44

18) A: 24 ÷ 27

1) 1.7 ÷ 8.5

We need to change them to whole numbers by shifting the decimal points one place to the right to get; (17/85)

2) 50 ÷ 0.1

Shift decimal one place to the right to get;

500/1

Quotient = 500

3) 0.86 ÷ 0.02

The dividend is usually the numerator. Let us shift both numerator and denominator by two decimal places to the right to get; 86 ÷ 2

Thus, new dividend = 86

4) 6.9 ÷ 0.3

Move decimal points one place to the right to get;

69 ÷ 3 = 23

5) 75.64 ÷ 0.61

Move decimal points two places to the right to get;

7564 ÷ 61

Numerator written as a factor of denominator gives;

(124 × 61)/61

Quotient = 124

6) 7.26 ÷ 0.22

Move decimal points two places to the right to get;

726/22

Numerator written as a factor of denominator gives;

(33 × 22)/22 = 33

7) 5.12 ÷ 0.10

Move decimal points two places to the right to get;

512/10 = 51.2

8) A 0.75 m pink ribbon was cut into 0.25 m strips. Thus;

Number of pieces = 0.75/0.25

Move both decimals 2 places to the right to get;

75/25 = 3 pieces

9) A bottle contains 27.5 ounces

You take 1.65 ounces for each dose.

Number of doses per bottle = 27.5/1.65

Move decimal points two places to the right; 2750/165

Number of doses per bottle = 16.67 doses

10) She earned Php256.25 for gardening.

She worked 20.5 hours the month.

Amount earned per hour = 256.25/20.5

move decimal places two points to the right to get;

Amount earned per hour = Php 12.5

11) 5.26 times 10

move decimal place two points to the right to get;

(526 × 1/100) × 10 = 52.6

12) 59 ÷ 7

Nearest multiple of 7 to 59 is 8.

Thus, 59 ÷ 7 = 8³/₇

⇒ 8.43

13) The one that gives a quotient of 6.78 is;

61 ÷ 9

14) How many 7 does 86 have?

This is; 86 ÷ 7

Nearest multiple of 7 to 86 is 84 which is 12 × 7

Thus, there are 12 numbers of 7 in 86.

15) Remainder if you divide 59 by 9

Nearest multiple of 9 to 59 is 54 which is 9 × 6.

Remainder = 59 - 54 = 5

16) When divisor is bigger than the dividend, it means the denominator is bigger than the numerator and so the quotient is an improper fraction which is a decimal.

17) 4 ÷ 9 = 0.444

Approximating to one decimal place = 0.4

18) The correct mathematical sentence with never ending decimal is;

24 ÷ 27

If the expression inside the absolute value bars which is -6 .Simplifying the expression |−6 + (−3)| (−3) + 8 ÷ 2 is: 9.

What is the expression?

Let simplify the given expression step by step:

|-6 + (-3)| = |-9| = 9

First calculate the expression inside the absolute value bars which is -6 + (-3) = -9. Then  take the absolute value of -9, which is 9.

(-3) + 8 ÷ 2 = (-3) + 4 = 1

We follow the order of operations (PEMDAS/BODMAS).

First perform the division:

8 ÷ 2 = 4

Add -3 to 4 which gives us 1.

Simplified expression :

9 * 1 = 9

Solve the following system of equations.
y = 2x + 1
y = x2 – 5x + 7

Answers

The solution of the system of equation is (6, 13) and (1, 3).

How to solve system of equation?

The system of equation can be solved using substitution method. Therefore, let's solve the system of equation by substitution method.

y = 2x + 1

y = x² - 5x + 7

substitute the value of y in equation(ii)

2x + 1 =  x² - 5x + 7

x² - 5x + 7 - 2x  - 1 = 0

x² - 7x + 6 = 0

x² - x - 6x + 6 = 0

x(x - 1) - 6(x - 1) = 0

(x - 6)(x - 1) = 0

x = 6 and x = 1

Hence,

when x = 6

y = 2(6) + 1

y = 12 + 1 = 13

when x = 1

y = 2(1) + 1

y = 3

Step-by-step explanation:

AB:BD is split into a total of 3+4=7 parts.

AC:CD is split into a total of 3+2=5 parts.

So, if the two ratios are put on a number line together with the points A, B, C, and D, the number line would be split into a total of 35 parts (the LCM of 7 and 5).

AB would be (3/7)*35=15.

CD would be (2/5)*35=14

BC would be 35-(15+14)=6

So, the ratio is 15:6:14.

If Y varies directly as x and y= 49 when x= 40, find y if x =34

Answers

Answer:

y = 41.65

Step-by-step explanation:

Given y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 49 when x = 40

49 = 40k ( divide both sides by 40 )

[tex]\frac{49}{40}[/tex] = k = 1.225

y = 1.225x ← equation of variation

When x = 34 , then

y = 1.225 × 34 = 41.65

I have invested for a loan of Php 5,000, and I need to repay in one lump sum at the end of one year. What annual interest rate corresponds to a lump-sum payment of Php 5,425?​

Answers

Based on the information given, it can be deduced that the annual interest rate will be 8.5%.

Principal = 5000

Interest = 5425 - 5000 = 425

Time = 1 year

Rate = Unknown.

Simple Interest = PRT / 100

425 = (5000 × R × 1)/100

42500 = 5000R.

R = 42500/5000

R = 8.5%

Which fraction is the same as 3.375?

Answers

Answer: 27/8 or 3 3/8

Step-by-step explanation:

Write 3.375 as 3.375/1

then you take the numerator 3.375 and multiply it by 1000. Multiplying is to make 3.375 a whole number. Whatever you do to the numerator, you have to do to the denominator. So, we take 1x1000 aswell. Then our fraction would be 3375/1000.  

   Then, we would find the greatest common factor. The greatest common factor, or GCF, is the greatest factor that divides two numbers. To find the GCF of two numbers: List the prime factors of each number. The GCF is 125. Then you divid 125 by the fraction, (which means that you divid the number by both the numerator and denominator) and you get the answer, which is 27/8.

  If the question is asking you to turn the fraction into a mixed number, you would have to find out how many times 8 going into 27. It goes in 3 times.  That is ur whole number. Then do 8x3 to get 24. take 27 and subtract 24 to get 3. that 3 is your numerator. The denominator stays the same.  ur final answer as a mixed number is 3 3/8.

b. Use the linear function to predict how many deer will be in the park in 3 years.
c. In how many years will there be 5,325 deer left in Sharon Woods Park?

Answers

The linear equation used to represent this situation is y = -75x + 6000

A linear equation is in the form:

y = mx + b;

where y, x are variable, m is the slope of the line and b is the y intercept.

Let y represent the amount of deer present in x years. There are 6000 deer presently, hence a = 6000. Also 75 more deer die than are born each year. Hence m = -75.

The linear equation is given by:

y = -75x + 6000

In 3 years:

y = -75(3) + 6000

y = 5775

For there to be 5325 deer:

5325 = -75x + 6000
