[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:

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

x = 10,893 km

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.

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%

Answer:

135°

Step-by-step explanation:

total = 360°

360° = 90° + 135° + x°

x° = 360° - (90° + 135°) = 360° - 225°

x° = 135°

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°.

The greatest common factor of 8m, 36m³, and 12 is 4.

4(2m), 4(9m³), and 4(3).

The HCF is the largest value that divides all three of them.

The greatest common factor of 8m, 36m³, and 12 is; 4.

Greatest common factor, as the name implies, is greatest among all common factors among the quantities given.

We could factorize the quantities in smallest relative factors possible (the level of factors over which all quantities can form themselves), and collect as many common factors as we could.

Factorize the given numbers and identify all common factors. To get the GCF(Greatest common factor) multiply all common factors;

The Common factors are: 2 and 2, their product is 2 x 2=4, then

4(2m) =  2 x 2 x2 x m

4(9m³) =  2 x 2 x3 x3 x m x m x m

4(3) = 2 x 2 x3

Hence, the greatest common factor is 4.

Answer:

The lengths are 5, 12, and 13.

Step-by-step explanation:

Let x represent the shorter leg of the triangle. Since the other leg is 7 cm more, the longer leg is x+7. Since the length of the hypotenuse is 3 cm more than double that of the shorter leg, the hypotenuse is 2x+3.

The Pythagorean Theorem may be used to find the lengths.

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]  a, b are the short and long lengths and c is the hypotenuse

→ [tex]x^{2} + (x+7)^{2} = (2x+3)^{2}[/tex]

→ [tex]x^{2} + x^{2} + 14x + 49 = 4x^{2} + 12x + 9[/tex]

→ [tex]2x^{2} + 14x + 49 = 4x^{2} + 12x + 9[/tex]

→ [tex]2x^{2} - 2x - 40 = 0[/tex]

→ [tex]x^{2} - x - 20 = 0[/tex]

→ [tex](x-5)(x+4) = 0[/tex]

→ [tex]x = 5[/tex] (The length cannot be negative)

The shorter leg, x, is 5 cm. Since the longer leg is x+7, it is 12 cm. Since the length of the hypotenuse is 2x+3, the hypotenuse is 13 cm.

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

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

Answer:

1/2

Step-by-step explanation:

in point slope form (y-h) = slope(x-k)

The equation in the slope-intercept form will be y = x/2 + 7/2. Then the slope of the equation is 1/2.

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.

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
