Answer:

1) 350

2) 195.83

Step-by-step explanation:

Tuition fee = $12, 000 per year.

30% of it's being paid off by the scholarship, so she'll have to pay:

[tex] = 12000 - ( \frac{30}{100} \times 12000) [/tex]

[tex] = 12000 - 3600[/tex]

[tex] = 8400[/tex]

She'll have to pay $ 8400 by herself, her savings.

If she's saving $ 8400 for two years, she's actually saving $ 8400 for 24 months!

for one month, it'll be

= 8400/ 24

= $ 350 per month

one year fee = $ 10, 700

uncle pays half of it, I.e., 10700/ 2

= $ 5, 350

he gets a grant for $ 3,000

so, the part of the fee he ain't paying

= 5,350 + 3000

= $ 8,350

So, he'll have to save:

= 10,700 - 8,350

= $ 2,350

that is per year,

for per month = 2350/ 12

= $ 195.83

Answer:

D) -2.14< root10 <|-2.8|

Step-by-step explanation:

the value for -2.14 is as plain as you can see, the negative version of 2.14.

The square root of 10 is 3.16227766.

The lines next to -2.8 is asking for the absolute value of -2.8, or the distance between that number and zero. The distance between -2.8 and 0 is positive 2.8, because distance can't be negative.

The 3 numbers taken from the explanations are -2.14, 3.16, and 2.8. Ranking them from least to greatest would give you -2.14, 2.8, 3.16, or -2.14< root10 <|-2.8|

Correct answer: [tex]b = \frac{2A}{h}[/tex], first option.

[tex]A=\frac{bh}{2}[/tex]

[tex]2*A=\frac{bh}{2}*2[/tex]  | multiply both sides by 2, 2's cancel out on the right.

[tex]2A=bh[/tex]

[tex]\frac{2A}{h} =\frac{bh}{h}[/tex]  | divide h on both sides, h's cancel out on the right

[tex]b = \frac{2A}{h}[/tex]

bye

Step-by-step explanation:

9. ⅔×½=⅓ ( the 2 in the numerator cancel out with the 2 in the denominator).

12. ⅓×¼=¹/(3×4) = ¹/12. (multiply the denominators 3 & 4)

15. ⁴/10×⅖= 4/25. (divide 2 in the numerator with the 10 in the denominator which gives the quoetiont 5) .

Answer:

72.55 ≤ x≤ 123.40

Step-by-step explanation:

c = 16.95x + 4.75,

We have to purchase a minimum of 4 games

Let x = 4

c (4) = 16.95(4) + 4.75

c(4) =67.8+4.75 = 72.55

This is the smallest amount we will spend

The most we will purchase is 7 games

Let x = 7

c (7) = 16.95(7) + 4.75

c(7) =118.65+4.75 = 123.40

This is the largest amount we will spend

The range is

72.55 ≤ x≤ 123.40

The point of intersection is the point where two or more functions meet.

The graphs of the hyperbola and ellipse have 0 point of intersection

The given parameters are:

[tex]\mathbf{3x^2 - 4y^2 + 4x - 8y + 4 = 0}[/tex]

[tex]\mathbf{3x^2 + y^2 + 4x - 3y + 4 = 0}[/tex]

To determine the points of intersection, we simply equate both equations.

So, we have:

[tex]\mathbf{3x^2 + y^2 + 4x - 3y + 4 = 3x^2 - 4y^2 + 4x - 8y + 4 }[/tex]

Cancel out the common terms

[tex]\mathbf{y^2 - 3y = - 4y^2 - 8y }[/tex]

Collect like terms

[tex]\mathbf{y^2 +4y^2= 3y - 8y }[/tex]

[tex]\mathbf{5y^2= - 5y }[/tex]

Divide through by 5

[tex]\mathbf{y^2= - y}[/tex]

Divide through by y

[tex]\mathbf{y= -1}[/tex]

The system of equation does not give room to calculate the x-coordinate at the x-axis.

Hence, the graphs of the hyperbola and ellipse have 0 point of intersection

B = L

Step-by-step explanation:

We can see that there are double lines between BC and LM, and a triple line curves at Angle B and Angle L.

We can conclude that:

A = K

B = L

C = M

C = K (NO)

BA = MK (NO)

M = C (YES)

BC = LM (YES)

B = L (YES)

It will take 19 years for the countdowns to reach $ 14,989.87

Given that Heather invest $ 3377 in a retirement account with a fixed annual interest rate of 8% compounded two times per year, to determine how long will it take for the countdowns to reach $ 14,989.87 the following calculation must be performed:

Initial value x (1 + interest rate / compounding times) ^ (years x compounding times) = Compound interest

Answer:

w=-13/4

w=2

Step-by-step explanation:

|8w+5|=21

Step by step solution :

STEP

1

:

Rearrange this Absolute Value Equation

Absolute value equalitiy entered

     |8w+5| = 21

STEP

2

:

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |8w+5|

For the Negative case we'll use -(8w+5)

For the Positive case we'll use (8w+5)

STEP

3

:

Solve the Negative Case

     -(8w+5) = 21

    Multiply

     -8w-5 = 21

    Rearrange and Add up

     -8w = 26

    Divide both sides by 8

     -w = (13/4)

    Multiply both sides by (-1)

     w = -(13/4)

    Which is the solution for the Negative Case

STEP

4

:

Solve the Positive Case

     (8w+5) = 21

    Rearrange and Add up

     8w = 16

    Divide both sides by 8

     w = 2

    Which is the solution for the Positive Case

STEP

5

:

Wrap up the solution

w=-13/4

w=2

A ratio will just be trying to find whole number versions of these decimals and then compare them side by side (always divide the larger number by the smaller number).

Therefore:

[tex]\frac{0.0000275}{0.000005}=5.5=\frac{5.5}{1}[/tex]

However, this isn't a proper ratio. Generally, ratios are whole numbers. Since it's 5.5, we can easily make this a whole number by multiplying it by 2. Keep in mind though, what we do to one number we do to the other! So:

[tex]\frac{2}{2}(\frac{5.5}{1})=\frac{2*5.5}{2*1}=\frac{11}{2}[/tex], technically this is a better format since it's whole numbers, but it gives you the ratio (11:2) which is a bit tougher to interpret than (5.5:1)

Therefore, the ratio we'll use is 5.5:1 for simplicity's sake:

From this ratio, we can see that the red tablet is 5.5x the size of the white tablet.
