round to the nearest tenth

Answer:

the original price was $53.33

Step-by-step explanation:

$x ---- 100%

$40 ------- 75% (this is because 25% of it's just 75% of the actual price)

[tex]75\cdot x = 100\cdot 40\\\\75x = 4000\\\\x=53.33[/tex]

===============================================

Work Shown:

x = original price

25% = 25/100 = 0.25

25% of x = 0.25x = discount, or amount saved

final price = (original price) - (discount)

final price = (x) - (0.25x)

final price = 0.75x

0.75x = 40

x = 40/0.75

x = 53.333333

x = 53.33

The original price is $53.33

The discount, or amount saved, is 0.25*x = 0.25*53.33 = 13.3325 = 13.33 dollars.

This means the sale price is 53.33 - 13.33 = 40

We can also see this through computing 0.75*x = 0.75*53.33 = 39.9975 = 40, which matches with the given sale price.

Note how I'm rounding to the nearest penny when needed.

Answer:

9°

Explanation:

So, since the arrow is pointing to a RIGHT angle, you have to know the right angle's degree is 90° so set up an equation.

11x - 9 = 90

Now you solve it. Here's a step by step:

11x - 9 = 90

Add nine to nine and ninety. Since the nine in this equation is negative, it'll cancel it out. Now here's what you have left to solve:

11x = 99

Divide -11 from 11 and 99.

x = 9

If you feel like you're wrong, fill it in!

11(9) - 9 = 90

11 x 9 = 99

99 - 9 = 90

There you go!

A function is said to be be one-to-one ( injective) if every y-value has only one corresponding x-value. The given function is ,

[tex]\bf \implies f(x) = 2x^3-5\\\\\bf\implies y = 2x^3-5 [/tex]

Here I have made the graph of " Desoms Graphing calculator. "

Now ,on plotting its graph we see that every y-value has only one corresponding x-value . Hence , ihe given function is a injective function that is one to one function.

Answer:

Viktor will have $5,800 in his account after 5 years

Step-by-step explanation:

Compound Interest

It happens when interest in the next period is then earned on the principal sum plus previously accumulated interest.

The formula is:

[tex]\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}[/tex]

Where:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

Viktor deposits P=$4,300 in an account that earns r=6% interest compounded monthly. Since there are 12 months in a year, n=12. The interest rate is converted to decimal: r=6/100=0.06. The final amount in the account after t=5 years is:

[tex]\displaystyle A=\$4,300\left(1+{\frac {0.06}{12}}\right)^{12*5}[/tex]

[tex]\displaystyle A=\$4,300\left(1.005}\right)^{60}[/tex]

Calculating:

A = $5,800

Viktor will have $5,800 in his account after 5 years

Step-by-step explanation:

Answer:

x = 11,  CD = 74, DE = 74, and CE = 37

Step-by-step explanation:

9x-25 = 6x+8

3x - 25 = 8

3x = 33

x = 11

CD = 9x - 25 = 99 - 25 = 74

DE = 6x+8 = 66 + 8 = 74

CE = 10x - 73 = 110 - 73 = 37

Answer:

93 cm.

Step-by-step explanation:

Answer:

Since the Airbus A300 model airplane was made to scale, measuring 36 centimeters, while the real airplane measures 54 meters, to determine the scale ratio between both planes, the following calculation must be performed:

36cm = 0.36m

0.36 = 1

54 = X

54 x 1 / 0.36 = X

150 = X

Therefore, the scale ratio between the model and the real plane is 150:1.

Answer:

  d.  The triangles are not similar

Step-by-step explanation:

The angle between the given sides is the same, so we need to compare the side ratios. In ΔQRS, we have ...

  QR/RS = 4/15

In ΔVTU, we have ...

  VT/TU = 8/32 = 1/4 ≠ 4/15

The triangles are not similar because corresponding sides are not proportional.

Answer:

1. y = 4x - 4

2. y = x + 2

3. y = -2x - 4

4. y = -x + 2

Step-by-step explanation:

Slope-intercept form is y = mx+b. As we know, m is the slope and b is the y-intercept. We need to find the slope and y-intercept and put them in the equation. Slope is rise over run, so we just count up then over until we get to an intersection. For the y-intercept, we look where the line crosses the y-axis.

Answer:

vertical, transitive, definition

Step-by-step explanation:

1 and 3 are vertical, as their opposite of each other

transitive means like if a = b and a =c then b = c

and a congruent to b means measure of angle a = measure of angle b

Answer:

Francisca was supposed to divide by 1/3, instead of subtracting by 1/3.

Step-by-step explanation:

She was completing the equation correctly until she subtracted 1/3 instead of dividing both sides. It should have been 5 divided by 1/3 or 15/3 divided by 1/3.

Answer:

= 1.072727 games per day

Step-by-step explanation:

This is a fraction equal to

118 games ÷ 110 days

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 110

118 games ÷ 110

110 days ÷ 110

=

1.072727 games

1 day

=

1.072727 games

day

= 1.072727 games per day

41.803 is 42 rounded to the nearest whole number because when you go past .5 you round to the nearest highest number, but when your below .5 then you round to the nearest lowest number.

Answer: 41.803 rounded to the nearest whole number would be 42. Whenever you go over .5 you round to the nearest highest number. For example, 41.6 would also be rounded to 42.
