What was the price for one notebook?

Answer:

Second one.

Step-by-step explanation:

A right triangle is a triangle with one right angle. A right angle can be shown with a box, we see that in 1, 3, and 4, there is a box, so that means 2 is not a right angle. We can also do out the math for number 2, so 67+67 = 134, and 180 - 134 is not 90.

Let me know if you have any questions.

Step-by-step explanation:

The angle is 40, because 180 - 140 = 40

And the reason for it is Adjacent angles

The measure of {x}, unknown angle is 40°.

The radian is the unit of angle in the International System of Units and is the standard unit of angular measure used in many areas of mathematics

Given is the image as shown in the figure.

We can write the measure of {x} as -

{x} = 180 - 140

{x} = 40°

Therefore, the measure of {x}, unknown angle is 40°.

Answer:

Step-by-step explanation:

First you have to calculate CB in order to use sin law to calculate ∠A

CB=[tex]\sqrt{18.4^{2} -13.2^{2} }[/tex]

CB=12.8(correct to nearest tenth)

After that, use sin law to calculate ∠A,

[tex]\frac{18.4}{sin90} =\frac{12.8}{sinA}[/tex]       or    [tex]\frac{sin90}{18.4} =\frac{sinA}{12.8}[/tex]

sinA=0.695...

A=44.079...

  =44.1(corrext to the nearest tenth)

Answer:

30.48 cm

Step-by-step explanation:

There are ~ 2.54 centimeters in 1 inch. If the ruler is 12 inches long, multiply 2.54 cm by 12:

12 inches x 2.54 cm = 30.48 cm.

Answer:

A)     [tex]m = \frac{1}{4}[/tex]

Step-by-step explanation:

Step(i):-

Given that the points are(-1,2) and (3,3)

Slope of the line

               [tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

Step(ii):-

Slope of the line

               [tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

             [tex]m = \frac{ 3-2}{3-(-1) }= \frac{1}{3+1} = \frac{1}{4}[/tex]

             [tex]m = \frac{1}{4}[/tex]

The line perpendicular to the line y=-3/4x+5 that includes the point (-3,-3) is y=-4/3x-7.

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

The given equation of a line is y=-3/4x+5 and the coordinate point is (-3, -3)

Here, slope of a line is -3/4.

The slope of a line perpendicular to given line is m1=-1/m2

Now, the slope of a line is -4/3

Substitute m= -4/3 and (x, y) =(-3, -3) in y=mx+c, we get

-3=-4/3 (-3)+c

c=-7

Substitute m= -4/3 and c=-7 in y=mx+c, we get

y=-4/3x-7

Therefore, the line perpendicular to the line y=-3/4x+5 that includes the point (-3,-3) is y=-4/3x-7.

Answer:

1.83

Step-by-step explanation:

1.78 + 5 cm

because it says she is taller so you add both

Height of Amy who is 5 cm taller than Jack is 1.83 meters.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Jack is 1.78 m tall and Amy is 5 cm taller than Jack.

Therefore, The sum of the height of Jack and 5 cm more is the height of

Amy.

Therefore,

178 cm + 5 cm = 183 cm is the height of Amy. (1m = 100 cm)

So, 183 cm is equal to 1,83 meters.

Step-by-step explanation:

The correct equation which represents the relationship in the table is,

⇒ p = m + 160.25

Where, m, the amount of money an employee has in the morning, and p, the amount of money an employee has later in the day after they receive their paycheck.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

This table represents the relationship between m, the amount of money an employee has in the morning, and p, the amount of money an employee has later in the day after they receive their paycheck.

Hence, By all options, we can check by substitute the given values.

So, By option 3;

The equation is,

⇒ p = m + 160.25

Substitute m = 200.25,

⇒ p = 200.25 + 160.25

⇒ p = 360.50

Thus, The correct equation which represents the relationship in the table is,

⇒ p = m + 160.25

Answer:

1 foot long

Step-by-step explanation:

If this fraction is closer to one it will be close to 16/16. And since 8 is half of 16, any fraction that is around 8/16 is closer to 1/2. 15 is closer 16 so this fraction is closer to one.

The side lengths of the squares is closer to 1 foot when rounded to the nearest foot length

There are basically two rules while rounding up numbers

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Non-zero digits are always significant

Zeros between non-zero digits are always significant

Leading zeros are never significant

Trailing zeros are only significant if the number contains a decimal point

Given data ,

Let the side lengths of the squares after rounding be represented as A

Now , the value of A is

The side lengths of the quilt with square shape be = 15/16 foot

Now , on rounding the value 15/16 , we get

A = 0.9375 feet

And , the value of A is much closer to 1 foot

Therefore , the value of A is 1 foot

Hence , the side lengths of the squares after rounding is 1 foot

Answer:

19.7 m

Step-by-step explanation:

Draw a circle to represent the ferris wheel with a 10.2 m radius. Draw a horizontal line through the circle center horizontal to the ground (at 13.1 m). Now draw a line from the center of the circle (ferris wheel) upward at 140 degrees until you reach the edge of the circle. Draw a line down from that point to the horizontal line at This is your right triangle to solve.

Hypotenuse is 10.2 m (radius of circle)

The angle of the triangle the supplementary angle of 140 degrees. 180-140=40 degrees

sin 40 degrees=rise /radius=rise/10.2

sin 40=0.6428=rise/10.2

rise=10.2(0.6428)

rise=6.6 m

13.1+6.6=19.7 m
