whats 41.803 rounded to the nearest whole number
Answers
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.

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.

A model is made of an Airbus A300 aeroplane.
The length of the model is 36 cm.
The length of the real aeroplane is 54 m.
Answers
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.

What is the surface area?
Answers
Area of triangle = 1/2 base x height
= (1/2 15) x 20
= 7.5 x 20
= 150 m square
Then we are gonna multiply the area of the triangle by 2 because there are two triangles making up this object.
= 150 m square x 2
= 300 square
Then we are gonna find the area of the rectangles
Area of rectangle 1 = length x width
= 7 x 25
= 175 m square
Area of rectangle 2 = 7 x 20
= 140 m square
Area of rectangle 3 = 15 x 7
= 105 m square
Then your gonna add all the area of the rectangles.
= 175 + 140 + 105= 420 m square
Then we are gonna add both the area of the triangles and the area of the rectangles and that would conclude the surface area.
300 m square + 400 m square = 700 m square
Therefore the surface area is 700 m square

Answers
Answer:

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

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.

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

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:
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!

what is the original price when the discount is 25% and the sale price is $40
Answers
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.
Viktor deposits $4,300 in an account that
carns 6% interest compounded monthly.
How much is in the account after five years?
Answers
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
