After school one night, I had to stop at the local office supply store and pick up a few items. I bought 2 packages of page dividers. They each cost $3.79. I bought one package of Post-It Tabs that cost $6.79. Finally, I bought a large binder for $11.99. Sales tax was 7.5% and I paid with a 50 dollar bill. How much change did I receive?

Answer:

28.25in

Step-by-step explanation:

An example for #5 is y=-8x+2, and an answer for 6. is y=6x+9. The formula is y=mx+b so the b is the y-int/y and the m is the slope/x. The x is the variable(the one beside the m).

Usually HA congruence is used in right angle triangles .as One common 90° right angle is present if Hypotenuse and adjacent angle remains similar the triangles are similar.

Answer:

x=134

Step-by-step explanation:

As angles in a triangle add up to 180 degrees

also angles on a straight line add up to 180

so 180-(64+70)=46

and 180-46=134

Answer:

[tex]M = (3,5.5)[/tex]

Step-by-step explanation:

Given

[tex]A = (-1,8)[/tex]

[tex]B = (7,3)[/tex]

Required

Determine the midpoint

This is calculated as thus

[tex]M = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Where:

[tex](x_1,y_1) = (-1,8)[/tex]

[tex](x_2,y_2) = (7,3)[/tex]

So, we have:

[tex]M = (\frac{-1+7}{2},\frac{8+3}{2})[/tex]

[tex]M = (\frac{6}{2},\frac{11}{2})[/tex]

[tex]M = (3,5.5)[/tex]

Hence;

The midpoint is (3,5.5)

The perimeter of the trapezoid is 9 + √2 + √5 units. then the correct option is D.

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

The points are J(-7, 4), K(-4, 4), L(-2, 3), and M(-8, 3).

We know that distance between two points will be given as

[tex]\rm D= \sqrt{(x_2 - x_1 )^2 + (y_2 - y_1)^2}[/tex]

The distance between JK will be

[tex]JK = \sqrt{(-4+7)^2 + (0)^2 } = 3[/tex]

The distance between KL will be

[tex]KL = \sqrt{(-2+4)^2 + (3-4)^2 } = \sqrt5[/tex]

The distance between LM will be

[tex]LM = \sqrt{(-8+2)^2 + (0)^2 } = 6[/tex]

The distance between JK will be

[tex]MJ = \sqrt{(-7+8)^2 + (4-3)^2 } = \sqrt2[/tex]

Then the perimeter will be

Perimeter = JK + KL + LM + MJ

Perimeter = 3 + √5 + 6 + √2

Perimeter = 9 + √2 + √5

Answer:

21000

Step-by-step explanation:

You move the decimal point over that many times as the power of 10.

IT is found that [tex]2.1 \times 10^4[/tex] can be written in standard form as 21,000.

Since Scientific notations have some of the profits are Better readability due to compact representation

The value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.

To convert from scientific notation to standard form, we simply move the decimal point to the right by the number of places indicated by the exponent (4 in this case).

Starting with  [tex]2.1 \times 10^4[/tex] , we move the decimal point four places to the right to get 21,000.

Hence,   [tex]2.1 \times 10^4[/tex] in standard form is 21,000.

the area of the surface of this design is 31 in long

Answer:

392 inches²

Step-by-step explanation:

10 inches × 6 inches = 60 inches²

60 inches² × 2 = 120 inches²

----------------------------------------------------------------------------------------------------------

(6 inches + 4 inches) × 6 inches = 10 inches × 6 inches = 60 inches²

60 inches² × 2 = 120 inches²

----------------------------------------------------------------------------------------------------------

(10 inches × 6 inches) + (4 inches × 4 inches) = 60 inches² + 16 inches² = 76 inches²

76 inches² × 2 = 152 inches²

Enzo can only buy 21 kiwis from the store.

Step-by-step explanation:

We have to divide

But since it's going too be hard for me to show you the long division, I'm just going to use a multiplication trick!

Let's find what is 20x0.99 first, because I feel like this CAN be the answer.

20x0.99=19.8

So this is not the answer

Now, let's try 22x0.99

22x0.99=21.78

So this is also not the answer.

Now, let's try 21, I think only this one can be the answer.

21x0.99=20.79

So hence, 21 is the right answer. Enzo can buy 21 Kiwis

The distance from the person to the base of the cliff is 269.78 meters.

The height of the building from the base of the cliff is 829.37 meters

The situation forms right angle triangle.

The building is constructed on top the cliff that is 300 meters high.

Right angle triangle has one of its sides as 90 degrees. Therefore, the sides can be found using trigonometric ratios.

The height of the building from the cliff is 300m. let's find the hypotenuse side of the angle of elevation formed to the cliff.

Using sin rule,

300 / sin (72 - 63) = y / sin (180 - 162)

300 / sin 9 = y / sin 18

300 sin 18 = y sin 9

y = 300 sin 18 / sin 9

y = 92.7050983125 / 0.156

y = 594.230769231

Therefore, how far the person to the base of the cliff can be calculated as follows;

cos 63 = adjacent / hypotenuse

cos 63 = x / 594.2307

x = 594.2307 cos 63

x = 269.775092454

x = 269.78 meters

Therefore, the distance from the person to the base of the cliff is 269.78 meters.

height of the cliff  / 269.78 = tan 63

height of cliff = 269.78 tan 63

height of cliff = 529.37493165

height of cliff = 529.37

The height of the building = 300 + 529.37 = 829.37493165 = 829.37 meters

Answer:

y=-1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-(-1))/(-5-0)

m=(-1+1)/-5

m=0/-5

m=0

y-y1=m(x-x1)

y-(-1)=0(x-0)

y+1=0

y=0-1

y=-1

i think it should be -1.6

if you add 7 to 9 it'll be 16.

if you divide -10 by 16 it'll give you -16/10.

simplify it and you should get -8/5 or -1.6.
