what is 9.45 rounded to the nearest whole number?
Answer:
[tex]\Huge \boxed{\mathrm{9}}[/tex]
[tex]\rule[225]{225}{2}[/tex]
Step-by-step explanation:
9.45
To round up to nearest whole number, we have to see the tenth place.
If the value of the tenth place is greater or equal to 5, then we round up the number to 10. If the value of the tenth place is less than 5, the we round up the number to 9.
The value of the tenth place is 4, which is less than 5, we will round up the number to 9.
[tex]\rule[225]{225}{2}[/tex]
9.45 rounded to the nearest whole number is 9.
Given that a decimal number 9.45 we need to round it to the nearest whole number,
To round a decimal number to the nearest whole number, you need to look at the digit immediately to the right of the decimal point.
In the case of 9.45, the digit to the right of the decimal point is 4. If this digit is less than 5, you simply remove all the digits after the decimal point and keep the whole number as it is.
However, if the digit to the right of the decimal point is 5 or greater, you increase the whole number by 1.
To round 9.45 to the nearest whole number, we examine the decimal part of the number, which is 0.45.
If the decimal part is less than 0.5, we round down to the nearest whole number. In this case, since 0.45 is less than 0.5, we round down.
Therefore, 9.45 rounded to the nearest whole number is 9.

Answer:
135°
Step-by-step explanation:
total = 360°
360° = 90° + 135° + x°
x° = 360° - (90° + 135°) = 360° - 225°
x° = 135°
A bank is offering a simple interest rate of 5% — that is, the bank will pay a fixed 5% of an initial investment as interest each year. By contrast, a stockbroker is offering a 4% interest rate compounded annually: 4% of the total value of the investment at the end of the year. If $1000 is invested in the bank and $1000 is invested with the stockbroker, after 4 years, what will be the total value of the two investments combined? Round to the nearest dollar.

Alex is drawing rectangles with different areas on a centimetre grid he can draw 3 different rectangles with an area of 12cmsquared a) How many different rectangles could alex draw with an area of 11cmsquared? B)Give a reason for ur anwser
Answer:
Alex can only draw a rectangle with an area of 11 cm²
The reason for the answer is that 11 is a prime number
Step-by-step explanation:
We are told that Alex is drawing rectangles with different areas on a centimeter grid, and he can draw 3 different rectangles with an area of 12 cm²
We have the minimum grid length of centimeters = 1 cm, since we assume that only integers can be used.
That is to say:
12 = 1 x 12
12 = 2 x 6
12 = 3 x 4
These are the 3 different rectangles with an area of 12 cm²
Now we have to find how many rectangles Alex could draw with an area of 11 cm²
11 = 1 x 11
Therefore, only one factorization is possible. Which means that you can only draw a rectangle with an area of 11 cm²
The reason for the answer is that 11 is a prime number, which means only the common factor of 1 and the number itself, that is, 11.
Which situation involves a change modeled by a positive number but an end result modeled by a negative number? A.Leo enters an elevator on the second floor and goes down four floors. B. A plane, flying at an altitude of 300 feet, descends 50 feet. C. Irene is scuba diving at –30 feet. She swims 10 feet toward the surface to watch a school of fish. D. April owes her brother $5. On Friday, she gets $10 for her allowance.
The positive number but a negative result would be :
C. Irene is scuba diving at –30 feet. She swims 10 feet toward the surface to watch a school of fish.
The positive value is she swam 10 feet up to the surface, but she is still below the surface, which would be a negative result.
The situation that would involve a change that is from a positive number but ended in a negative number is option C.
This option tells us that at the negative number she was 30 feet below the surface of the water, while at positive number she was 10 feet up the water surface.

PLEASE HELP ... how many students are in each van? And how many students are in each bus ?
Answer:
7 students in each van and 52 students in each bus.
Step-by-step explanation:
v = no of students in van, b = no of student in bus
High school A ⇒ 3v + 6b = 333 ---------- Equation (1)
High school B ⇒ 11v + 6b = 389 ------------ Equation (2)
Solve equation (1) & (2) simultaneously :
11v + 6b = 389
3v + 6b = 333
----------------------- MINUS
8v + 0 = 56
v = 56 / 8
v = 7
Put v = 7 into Equation (1) to get b:
3v + 6b = 333
3 (7) + 6b = 333
21 + 6b = 333
6b = 312
b = 312 / 6
b = 52
So there are 7 students in each van and 52 students in each bus.

Hear is a rectangle 7 cm 3 cm the squre has the same peremeter as the rectangle what is the side length of this squre ______7cm_______ l l l l 3 cm l _______________l
Answer:
5 cm
Step-by-step explanation:
The rectangle has a length (l) of 7 cm and a width (w) of 3 cm. Therefore, the perimeter of the rectangle is:
Perimeter of rectangle = 2(l + w) = 2(7 + 3) = 2(10) = 20 cm
Since the rectangle and the square has the same perimeter, Therefore, the perimeter of the square is:
Perimeter of square = 2(l + w). But the length and width of a square are the same (i.e l = w). Therefore:
Perimeter of square = 4l
20 = 4l
l = 20 / 4 = 5 cm
Each side of the square has a length of 5 cm

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The linear equation is given below.
y - 4 = 1/2 (x - 1)
Convert the equation into a slope-intercept form. Then we have
y - 4 = 1/2 (x - 1)
y - 4 = x/2 - 1/2
y = x/2 - 1/2 + 4
y = x/2 + 7/2
The equation in the slope-intercept form will be y = x/2 + 7/2. Then the slope of the equation is 1/2.

Scores of an IQ test have a bell-shaped distribution with a mean of 100 and a standard deviation of 20. Use the empirical rule to determine the followinWhat percentage of people has an IQ score greater than 120?
Answer:
Percentage of people with IQ greater than 120 is 84.134%
Step-by-step explanation:
First thing we do here is to calculate the
z-score
Mathematically;
z-score = (x-mean)/SD
here, x = 120, mean = 100 while SD = standard deviation = 20
z-score = (120-100)/20 = 20/20 = 1
The probability we want to calculate is;
P(x > 120) or P(z >1)
we proceed to use the standard score table to get this;
From the standard score table ;
P(z >1) = 0.84134
which is in percentage = 84.134%

noRatio of three angles of a triangle is 1 : 2 : 3. Find the angles.
Answer:
30⁰ , 60⁰ , 90⁰
Step-by-step explanation:
Let the angles x , 2x , 3x
By angle sum property:
x + 2x + 3x = 180⁰
6x = 180⁰
x = 30⁰
Angles are : 30⁰ , 60⁰ , 90⁰
Let one angle be x, the second 2x and the third 3x.
x + 2x + 3x = 180 degrees (angle sum property of a triangle)
6x = 180 degrees
x = 180/6
x = 30 degrees
So one angle is 30°, the second is 60°, and the third is 90°.

Need help ASAP please and thank you
Answer:
Step-by-step explanation:
The only angle we are given directly inside that triangle is angle R, 87 degrees. We can use the fact that the exterior angle at T is 92, so the interior angle is 180 - 92 = 88. Now we can find angle S: 180 - 87 - 88 = 5. So angle S = 5 degrees. The Law of Sines can be used now to find the length of SR:
[tex]\frac{sin5}{950} =\frac{sin88}{x}[/tex]
Cross multiply to get
x sin5 = 950 sin88 and
[tex]x=\frac{950sin88}{sin5}[/tex] so

Terry bought some gum and some candy. The number of packs of chewing gum was one more than the number of mints. The number of mints was three times the number of chocolate bars. If gum cost 6 cents a pack, mints cost 3 cents each, and chocolate bars cost 10 cents each, how many of each confection did he get for 80 cents?
Answer:
Hi!!
Step-by-step explanation:
7 = chewing gum
6 = mints
2 = chocolate
Answer:
number of packs of chewing gum is 7
number of mints is 6
number of chocolate bars is 2
Step-by-step explanation:
number of packs of chewing gum → x, cost 6¢
number of mints → y = x-1 =3z, cost 3¢
number of chocolate bars → z = y/3 = (x-1)/3, cost 10¢
put in equation 6x + 3y +10z = 80 plug in term of x
6x +3(x-1) +10((x-1)/3) =80 multiply each side by 3
18x +9(x-1) +10(x-1) =240 distribute
18x+9x-9+10x-10 =240 combine like terms
37x-19 = 240 add 19 in each side
37x =259
x = 7
plug into y = x-1 = 7-1 = 6 so y=6
and z = y/3 =6/3 =2 so z = 2
