Which unit rate is the lowest price a.6oz of chocolate chips for $2.49

rotation of 90 degrees counterclockwise about the origin, point O, then a reflection across the x-axis reflection across the y-a

SpyIntel [72]

Answer:

The point O can be (x,y) or (-x,y) or (-x,-y) or ( x,-y) reason being that you haven't given point O lies in which quadrant.

Rotation through 90° counter clockwise

(x,y) = (-y,x)

(-x,y)=(-y,-x)

(-x,-y)=(y,-x)

(x,-y) =(y,x)

Then Reflection across X axis has taken place.

(-y,x) = (-y,-x)

(-y,-x)=(-y,x)

(y,-x)=(y,x)

(y,x)=(y,-x)

Then a reflection across the y-axis has taken place.

(-y,-x)=(y,-x)

(-y,x) = (y,x)

(y,x) =(-y,x)

(y,-x)=(-y,-x)

Then a translation a units to the right and b units up has taken place.

(y,-x)=(y+a,-x+b)

(y,x) =(y+a, x+b)

(-y,x) =(-y+a,x+b)

(-y,-x)=(-y+a,-x+b)

Then a rotation of 180 degrees counterclockwise about the origin has taken place.

(y+a,-x+b)=[-(y+a),-(-x+b)]

(y+a, x+b)=[- (y+a), -(x+b)]

(-y+a,x+b)=[-(-y+a),-(x+b)]

(-y+a,-x+b) =[-(-y+a),-(-x+b)]

Now Again a reflection across the Y axis has taken place.

[-(y+a),-(-x+b)]=[(y+a),-(-x+b)]

[-(y+a),-(x+b)]=[(y+a),-(-x+b)]

[-(-y+a),-(x+b)]=[(-y+a),-(x+b)]

[-(-y+a),-(-x+b)]=[(-y+a),-(-x+b)]

Totally depends on value of a and b on which quadrant these point lies.

Find the surface area of the cylinder use 3.14 for pi

elena55 [62]

Answer:

351.658 square in

Step-by-step explanation:

First find the circumference of the circle

C = 25.13

Find area of the circle

A = 50.27

Multiply the circumference by the height

25.13 × 10 = 251.3

Add 251.3 with 50.27 twice

251.13 + 50.27 + 50.27 ≈ 351.658

Therefore your answer is D) 351.658 square in

Lisa [10]

Answer:

B. 200 doses

Step-by-step explanation:

Given,

1 dose is required for 100 mg,

Since, 1 mg = 0.001 g,

⇒ 100 mg = 0.1 g

⇒ 1 dost is required for 0.1 g,

Thus, the ratio of doses and quantity ( in gram ) is $\frac{1}{0.1}=10$

Let x be the doses required for 20 grams,

So, the ratio of doses and quantity is $\frac{x}{20}$

$\implies \frac{x}{20}=10$

$\implies x=200$

Hence, 200 doses can be obtained from 20 grams of the drug.

Option 'B' is correct.

A rectangle has length represented as (R +5) and width represented as (R + 2).

svetlana [45]

Answer:

4(R + 5 + R + 2) [Option B]

Step-by-step explanation:

GIVEN :-

Length = R + 5
Width = R + 2

TO FIND :-

Perimeter of the rectangle

FORMULAE TO BE USED :-

For a rectangle with length 'l' and width 'w' , its perimeter = 4(l + w)

SOLUTION :-

Perimeter = $4(R + 5 + R+2)$

= $4(2R + 7)$

= $8R + 14$

Your Overall grade is calculated by adding 35% of your Minor grade to 65% *

max2010maxim [7]

Answer:

69%

Step-by-step explanation:

Overall grade = 0.35*minor grade + 0.65*major grade

major grade: 0.65*61 = 39.65

minor grade: 0.35*84 = 29.4

total: 39.65+29.4 = 69.05

Rounded = 69%
