Answer:

a) $420 b) $399

Step-by-step explanation:

a) $600 = 100%

$60 = 10%

$60 times 3 gives 30% = $180

$600 - $180 = $420

b) $420 = 100%

$42 = 10%

$21 = 5%

this means, they profitted by $21.

so $420 - $21 = $399

therefore, $399 is the cost price

Answer:

87/100

Step-by-step explanation:

Answer:

It already is

Step-by-step explanation:

In order to write 0.87 as a fraction in simplest form is very simple. 0.87 is in the hundredths place, so the denominator will be 100 and the numerator will be 87. 87/100 is our new fraction, however it is already in simplest form.

Given:

A salesperson is paid $10 per week plus $8 per sale.

This week, the salesperson wants to earn at least $250.

To find:

The inequality represents the number of sales, s, the salesperson must make in order to meet that goal.

Solution:

Let s be the number of sales.

Fixed earnings = $10 per week

Earning on 1 sale = $8

Earnings on s sales = $8s

Total earnings = Fixed earnings + Additional earnings of sale

[tex]\text{Total earnings}=10+8s[/tex]

This week, the salesperson wants to earn at least $250. It means, total earning must be greater than or equal to 250.

[tex]10+8s\geq 250[/tex]

[tex]8s\geq 250-10[/tex]

[tex]8s\geq 240[/tex]

Divide both sides by 8.

[tex]s\geq 30[/tex]

Therefore, the inequality [tex]s\geq 30[/tex] represents the number of sales, s, the salesperson must make in order to meet that goal.

Answer:

1/24

Step-by-step explanation:

We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 11 by 8, and get 88.Then we multiply 7 by 12, and get 84.

Next we give both terms new denominators -- 12 × 8 = 96.

So now our fractions look like this:

88 /96 -84 /96

Step 2

Since our denominators match, we can subtract the numerators.

88 − 84 = 4

So the answer is:

4 /96

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:            

4 /96 ÷ 2 =2 /48

Let's try dividing by 2 again...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

2 /48 ÷ 2 =1 /24

Let's try dividing by 2 again...

No good. 2 is larger than 1. So we're done reducing.                                    There you have it! The final answer is:

11 /12 -7 /8=1 /24

Answer: a. 1734    b. 477000

Step-by-step explanation:

We know that,

Distributive property : a(b+c)  = ab+ac

a. 17 x 102

=  17 (100+2)

= 17 x 100 + 17 x 2  [Distributive property ]

= 1700+34

= 1734

b. 477×1035 -477×35​

= 477 (1035-35)  [Distributive property ]

= 477 (1000)

= 477000

Answer:

g(-3) = [tex]\frac{17}{4}[/tex]

g(2) = -3

g(5) = [tex]-\frac{7}{4}[/tex]

Step-by-step explanation:

Let us solve the question

∵ g(x) = [tex]-\frac{3}{4}[/tex] x + 2, x ≠ 2

→ That means we can use it for any value os x except 2

∵ g(x) = -3, x = 2

→ That means we will use it only if x = 2

We want to find g(-3)

∵ x = -3 ⇒ ≠ 2

∴ We will use g(x) = [tex]-\frac{3}{4}[/tex] x + 2

→ Substitute x by -3

∵ g(-3) =  [tex]-\frac{3}{4}[/tex] (-3) + 2

∴ g(-3) =  [tex]\frac{9}{4}[/tex]  + 2

∴ g(-3) = [tex]\frac{17}{4}[/tex]

We want to find g(2)

∵ x = 2

∴ We will use g(x) = -3

→ This is a constant function which means g(2) equal to -3

∴ g(2) = -3

We want to find g(5)

∵ x = 5 ⇒ ≠ 2

∴ We will use g(x) = [tex]-\frac{3}{4}[/tex] x + 2

→ Substitute x by 5

∵ g(5) =  [tex]-\frac{3}{4}[/tex] (5) + 2

∴ g(5) =  [tex]-\frac{15}{4}[/tex]  + 2

∴ g(5) = [tex]-\frac{7}{4}[/tex]

Answer:

We conclude that:

Step-by-step explanation:

From the given function g(x)

g(x) =   -1   if -2 < x ≤ -1

           0   if  -1 < x ≤ 0

            1    if  0 < x ≤ 1

            2   if  1 < x ≤ 2

When x = -1, then the correct value of g(-1) will be:

g(-1) = -1

The reason is that the output value of -1 includes the value of x = -1 in the interval, as  -1  if -2 < x ≤ -1 .

When x = -0.25, then the correct value of g(-0.25) will be:

g(-0.25) = 0

The reason is that the output value of 0 includes the value of x = -0.25 in the interval, as  0   if  -1 < x ≤ 0

When x = 2, then the correct value of g(2) will be:

g(2) = 2

The reason is that the output value of 2 includes the value of x = 2 in the interval, as 2   if  1 < x ≤ 2.

Therefore we conclude that:

Answer:

-7/8y²+3

Step-by-step explanation:

It seems like we are just combining like terms here. Like terms have the same variable raised to the same power. We have three terms here: two of them are y² terms and one is just a 3, so we can combine those two like terms and then just add 3.

5/8y²-3/2y²= -7/8y²

Now we just plop the three on the end and we're done!

The answer is C

Step-by-step explanation:

The roots are −1.87938524, 0.34729635, 1.53208888, −1.87938524, 0.34729635, and  1.53208888. That's 6 roots, which is C.

According to the Fundamental Theorem of Algebra, 6 roots exist for the polynomial function.

Fundamental Theorem of Algebra states that every polynomial equation of degree n with complex number coefficients has n roots, or solutions, in the complex numbers. The roots can have a multiplicity greater than zero.

Given polynomial function

[tex]f(x)=(x^{3}-3x+1 )^{2}[/tex]

It has [tex](x^{3} )^{2}[/tex] term in the given polynomial

The fundamental theorem of algebra guarantees that a polynomial equation has the same number of roots as its degree.

= 3 × 2

= 6

So, 6 roots exist for the polynomial function.

Answer:

x=-2500

Step-by-step explanation:

[tex]\sqrt{-4x} =100\\\\(\sqrt{-4x})^2=100^2\\\\-4x=10,000\\\\x=-\frac{10000}{4}\\\\x=-2500[/tex]

The given can be solved by simplifying the equation to make x the subject

of the equation.

Reasons:

The equation is; √(-4·x) = 100

The above equation can be expressed as follows;

By squaring both sides, we get;

[tex]\displaystyle \mathbf{ \left(-4 \cdot x \right)^{\frac{1}{2} \times 2 }} = 100^2[/tex]

Which gives;

[tex]\displaystyle \left(-4 \cdot x \right)^{\frac{1}{2} \times 2 } = \left(-4 \cdot x \right)^{1 }= -4 \cdot x = 100^2[/tex]

[tex]\displaystyle -4 \cdot x = 100^2 = 100 \times 100 = \mathbf{10,000}[/tex]

[tex]\displaystyle -4 \cdot x = 10,000[/tex]
