susan bought a calculator for $120. She had to pay a sales tax of 10% on the price. How much change would she receive from $140?

Answer:  19 people will be represented by an angle 152 degrees.

Step-by-step explanation:

Set up a  proportional relationship to solve for this

[tex]\frac{360}{152} = \frac{45}{y}[/tex]        Cross multiply

360y = 6840   Divide both sides by 360

y =  19

Answer:

Ratios of corresponding sides are equal:

If ΔABC ~ ΔXYZ, the ratios below should be equal:

Ratios are different so the triangles are not similar

Answer:

Step-by-step explanation:

Hello,

1. Follow PEMDAS, for instance, which is Parentheses, Exponents, Mult., Div., and so on.

This will help you simplify on each side of the inequality sign.

2. Signs of inequalities will switch (> becomes <, and < becomes >) when dividing by a negative number on both sides of an inequality.

Try to work with this first. If you need more help, let me know.

Answer:

Step-by-step explanation:

The absolute value, as "distance from zero", is used to define the absolute difference between arbitrary real numbers, the standard metric on the real numbers. Complex numbers [ edit ] The absolute value of a complex number z {displaystyle z} is the distance r {displaystyle r} of z {displaystyle z} from the origin.

Answer: 81

Step-by-step explanation:

Answer: 24 square inches

Step-by-step explanation:

To get the whole area Multiply length x width

12 x 7 = 84

Now we get the area of the space in the rectangle

6 x 5 = 30 and multiply that by 2 since there are 2 spaces

in the rectangle.

30 x 2 = 60

84 - 60 = 24

Step-by-step explanation:

Answer:

It is 2

Step-by-step explanation:

The greatest common factor is 2 because 2×16=32

also works for 24 because 2×24=48

then yes it works again for 2×12=24

division is also very helpful

Answer:

Hannah = 20, Sal = 4

Step-by-step explanation:

Total number of sweets = 24

Ratio in which the sweets was shared;

Hannah : Sal = 5 : 1

Hannah gets:

Hannah = 5 / ( 5+1)  * 24 = 5/6  * 24 = 5 * 4 = 20

Sal gets:

Sal = 1 / ( 5+1)  * 24 = 1/6  * 24 = 1 * 4 = 4

Dave has 9 bottles of water

Step-by-step explanation:

12-3=9

Answer:

for simplifying these ratio

we have to first

find out GCF of all

which is 6

now divide each of them with 6

then we will get. 3:4:7

hope it will help

Answer:

3:4:7

Step-by-step explanation:

First find HCF

HCF:6

18/6=3

24/6=4

42/6=7

Therefore the simplified ratio of 18:24:42 is:

3:4:7

Answer:

[tex]266[/tex] [tex]\frac{2}{3}[/tex] [tex]yards[/tex]

Step-by-step explanation:

1. Approach

First, convert the dimensions of the room from feet to yards. Remember, the conversion rate between feet and yards is, [tex]3feet=1yard[/tex]. Next, find the area of the room by multiplying the length by the width.

2. Convert the unit of measurement

The measurement unit is given in feet, one must convert it into yards. The conversion rate between yards and feet is, [tex]3feet=1yard[/tex].

[tex]60feet=20yards\\\\40feet=13\frac{1}{3}yards[/tex]

3. Find the area of the room

Now multiply the length by the width to find the area of the room.

[tex]20yards*13\frac{1}{3}yrads\\\\= 20 * \frac{40}{3}\\\\=\frac{800}{3}\\\\= 266\frac{2}{3}_{.}yards^{2}[/tex]

Answer:

[tex]\boxed {\boxed {\sf a= 705.6 \ units^2 }}[/tex]

Step-by-step explanation:

Since we are given the central angle in radians, we should use this formula for the sector area:

[tex]a=\frac{1}{2}r^2 \theta[/tex]

where r is the radius and θ is the angle in radians.

The radius is 14 units and the angle is 7.2 radians.

[tex]r= 14 \ units \\\theta= 7.2[/tex]

Substitute the values into the formula.

[tex]a= \frac{1}{2} (14 \ units)^2 (7.2)[/tex]

Solve the exponent.

[tex]a=\frac{ 1}{2} (196 \ units^2)(7.2)[/tex]

[tex]a=\frac{ 1}{2}(1411.2 \ units^2)[/tex]

Multiply by 1/2 or divide by 2.

[tex]a= 705.6 \ units^2[/tex]

The area of the sector is 705.6 square units.

Answer:

Slope: -6 Y-intercept: -4

Step-by-step explanation:

You have to put the 4 on the same side as the expression so that y-6x-4=0 so the -6x is the slope and the -4 is the y-int because of y=mx+b
