Answer 1

Answer:

a) 5  b) 1  c) 0  d) -4

Explanation:

a) 10[(1/2+1/4) + 2(1/8)] ÷ 2

Ok, there's a lot going on. You will want to follow PEMDAS, the acronym of the Order of Operations. It stands for Parentheses, Exponents, Multiplication/Division, and Addition/Subtraction. The M/D can be switched depending on what comes first from left to right, and same goes for A/S.

First, start off by doing everything in the brackets.

Let's add 1/2 and 1/4. To add fractions, they have to have a common denominator. I'm making 1/2 into 2/4 but multiplying the top and bottom by 2. Now it is 2/4 + 1/4 so we can add to get 3/4.

The other thing inside the brackets is 2(1/8). We can just multiply straight across and get 2/8. This can be simplified to 1/4.

Now, we add 3/4 and 1/4. The denominators are already the same, so we can just add them together to get 4/4 or 1.

Rewriting the equation, we now have 10(1)÷2

10•1 = 10

10 ÷ 2 = 5

The answer to question a is 5.

b) √(0.6)² + (0.8)²

First, we need to square both terms. Squaring is the same as multiplying the number by itself.

0.6 • 0.6 = 0.36

0.8 • 0.8 = 0.64

Add them together: 0.36 + 0.64 = 1

√1 = 1

The answer to question b is 1.

c) (1/5 - 3/5) • √6•3/2 + (√36 ÷ √5²)

Let's start with the first bit: (1/5 - 3/5)

The denominators are the same, so just subtract and you get -2/5

The second bit now: [tex]\sqrt{6 *\frac{3}{2} }[/tex]

Multiply across and you get 18/2, which can be simplified to 9

√9 = 3

The third section: ([tex]\sqrt{36}[/tex]÷ [tex]\sqrt{5^{2} }[/tex])

The square root of 36 = 6 (because 6•6=36, so it's right)

The square root and the square cancel each other out, so the second part is 5.

6 ÷ 5 = 1.2

Now put it all together: -2/5 • 3 + 1.2

I'm making the 1.2 into a fraction so it is the same as the fraction: 1.2 = 6/5

We now have -2/5 • 3 + 6/5

First we multiply -2/5 and 3 across:

-2/5 • 3 = -6/5

Now we add -6/5 and 6/5 across:

-6/5 + 6/5 = 0

d) [-1.5 + √0.25 - (-0.75)] • 2^4

Doing the brackets first:

The square root of 0.25 = 0.5 (because 0.5 • 0.5 = 0.25)

-1.5 + 0.5 - -0.75

-1 + 0.75 (subtracting a negative make a positive)

-0.25

-0.25 • 2^4

2^4 = 16 (this is saying 2•2•2•2 which is 16)

-.25 • 16 = -4

A scientist mixes water (containing no salt) with a solution that contains 20% salt. She wants to obtain 140 ounces of a mixture that is 5% salt. How many ounces of water and how many ounces of the 20% salt solution should she use?

Answers

Let x represent ounces of water.
Ounces of 30% salt solution required = 140 - x

(Percentage of salt solution)(ounces of 30% solution required) = (5% salt solution needed)(extra salt solution needed)

(20/100)(140-x) = (5/100)*140
(1/5)(140-x) = (1/20)*140
28-1/5x = 7
Multiply both sides of the equation by 5 to isolate x:
5*(28-1/5x = 7)*5
140-x = 35
-x = 35 - 140
-x = -105
x = 105

Ounces of salt solution = 140 - 105 = 35

Therefore, 105 ounces of water is required and 35 ounces of salt solution is required

C. 6kg to 7kg
D. 15kg to 18kg
E. 5kg to 6kg

Answers

Answer:

C. 6kg to 7kg(is the old one)

Solving steps:

Answer:

60 : 72 = 5 : 6

Solution:

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 60 and 72 is 12

Divide both terms by the GCF, 12:

60 ÷ 12 = 5

72 ÷ 12 = 6

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 120 and 144 is 24

Divide both terms by the GCF, 24:

120 ÷ 24 = 5

144 ÷ 24 = 6

The ratio 120 : 144 can be reduced to lowest terms by dividing both terms by the GCF = 24 :

120 : 144 = 5 : 6

Therefore:

120 : 144 = 5 : 6

A) The ratio 60 : 72 can be reduced to lowest terms by dividing both terms by the GCF = 12 :

60 : 72 = 5 : 6

Therefore:

60 : 72 = 5 : 6

Answer:

30 : 36 = 5 : 6

b) Solution:

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 30 and 36 is 6

Divide both terms by the GCF, 6:

30 ÷ 6 = 5

36 ÷ 6 = 6

The ratio 30 : 36 can be reduced to lowest terms by dividing both terms by the GCF = 6 :

30 : 36 = 5 : 6

Therefore:

30 : 36 = 5 : 6

Answer:

6 : 7 = 6 : 7

c) Solution:

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 6 and 7 is 1

Divide both terms by the GCF, 1:

6 ÷ 1 = 6

7 ÷ 1 = 7

The ratio 6 : 7 cannot be reduced further by dividing both terms by the GCF = 1 :

This ratio is already in lowest terms.

Therefore:

6 : 7 = 6 : 7

Answer:

15 : 18 = 5 : 6

d) Solution:

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 15 and 18 is 3

Divide both terms by the GCF, 3:

15 ÷ 3 = 5

18 ÷ 3 = 6

The ratio 15 : 18 can be reduced to lowest terms by dividing both terms by the GCF = 3 :

15 : 18 = 5 : 6

Therefore:

15 : 18 = 5 : 6

Answer:

5 : 6 = 5 : 6

e) Solution:

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 5 and 6 is 1

Divide both terms by the GCF, 1:

5 ÷ 1 = 5

6 ÷ 1 = 6

The ratio 5 : 6 cannot be reduced further by dividing both terms by the GCF = 1 :

This ratio is already in lowest terms.

Therefore:

5 : 6 = 5 : 6

ASpoon is sold at a loss of 47%. If it was sold at 200
Calculate the Cost Price

Answers

Answer:

377.36(2decimal places)

Step-by-step explanation:

Solution

First write down all known info about problem

Loss(L) percent:47%

Selling price(SP):200

Cost Price is unknown but CP percent equals 100%(basic percent b'cos it represents the basic cost of the item)

When at a loss, the CP is higher than the SP so subtract the L% from the CP% to get the SP percent...

∴SP% equals CP%-L%

100%-47%:53% ∴SP%:53%

We can simply cross multiply now by saying,

If 53% equals 200

∴100% equals a variable(x)

Cross multiplying,we get:

53x equals (200×100) so dividing both sides by 53,

x equals 377.36(2 decimal places)

Therefore, the CP is 377.36

Graphing an interger function and finding its range for a given domain

Answers

For the function and given domain, the range is  {-9,-1,5,7}.

Linear Function

A linear function can be represented by a line. The standard form for this equation is: [tex]y=ax+b[/tex], for example, y=2x+7.

Domain and Range

The domain of a function is the set of input values for which the function is real and defined. On the other words, when you define the domain, you are indicating for which values x the function is real and defined.

While the domain is related to the values ​​of x, the range is related to the possible values ​​of y that the function can have.

The equation of this exercise, 2x+1,  is a linear equation because it presents the form: ax+b. Thus, you already know that your graph will be a line.

Find values of y for given domain:

For this, you should replace -5,-1, 2,3 for x in the equation 2x+1.

For x=-5,  [tex]y=2*(-5)+1=-10+1=-9[/tex]

For x=-1, [tex]y=2*(-1)+1=-2+1=-1[/tex]

For x=2, [tex]y=2*(2)+1=4+1=5[/tex]

For x=3, [tex]y=2*(3)+1=6+1=7[/tex]

Therefore, the range is {-9,-1,5,7}

Plot the graph

From the  values x of domain and the values of  y calculated previously, plot the points and draw the line. See the image attached.
